    The extended transnasal approach, a recent surgical advancements for the ventral skull base, allows excellent midline access to and visibility of the anterior cranial fossa, which was previously thought to be approachable only via a transcranial route. The extended transnasal approach allows early decompression of the optic canals, obviates the need for brain retraction, and reduces neurovascular manipulation. Between 2004 and 2007, 11 consecutive patients underwent transnasal resection of anterior cranial fossa meningiomas--4 olfactory groove (OGM) and 7 tuberculum sellae (TSM) meningiomas. Age at surgery, sex, symptoms, and imaging studies were reviewed. Tumor size and tumor extension were estimated, and the anteroposterior, vertical, and horizontal diameters were measred on MR images. Medical records, surgical complications, and outcomes of the patients were collected. A gross-total removal of the lesion was achieved in 10 patients (91%), and in 1 patient with a TSM only a near-total (> 90%) resection was possible. Four patients with preoperative visual function defect had a complete recovery, whereas 3 patients experienced a transient worsening of vision, fully recovered within few days. In 3 patients (2 with TSMs and 1 with an OGM), a postoperative CSF leak occurred, requiring a endoscopic surgery for skull base defect repair. Another patient (a case involving a TSM) developed transient diabetes insipidus. The operative time ranged from 6 to 10 hours in the OGM group and from 4.5 to 9 hours in the TSM group. The mean duration of the hospital stay was 13.5 and 10 days in the OGM and TSM groups, respectively. Six patients (3 with OGMs and 3 with TSMs) required a blood transfusion. Surgery-related death occurred in 1 patient with TSM, in whom the tumor was successfully removed. The technique offers a minimally invasive route to the midline anterior skull base, allowing the surgeon to avoid using brain retraction and reducing manipulation of the large vessels and

    Objectives The objectives of the study were to (1) study the anatomical variations of the tensor fold and its anatomic relation with transverse crest, supratubal recess, and anterior epitympanic space and (2) explore the most appropriate endoscopic surgical approach to each type of the tensor fold variants. Study Design Cadaver dissection study. Setting Temporal bone dissection laboratory. Subjects and Methods Twenty-eight human temporal bones (26 preserved and 2 fresh) were dissected through an endoscopic transcanal approach between September 2016 and June 2017. The anatomical variations of the tensor fold, transverse crest, supratubal recess, and anterior epitympanic space were studied before and after removing ossicles. Results Three different tensor fold orientations were observed: vertical (type A, 11/28, 39.3%) with attachment to the transverse crest, oblique (type B, 13/28, 46.4%) with attachment to the anterior tegmen tympani, and horizontal (type C, 4/28, 14.3%) with attachment to the tensor tympani canal. The tensor fold was a complete membrane in 20 of 28 (71.4%) specimens, preventing direct ventilation between the supratubal recess and anterior epitympanic space. We identified 3 surgical endoscopic approaches, which allowed visualization of the tensor fold without removing the ossicles. Conclusions The orientation of the tensor fold is the determining structure that dictates the conformation and limits of the epitympanic space. We propose a classification of the tensor fold based on 3 anatomical variants. We also describe 3 different minimally invasive endoscopic approaches to identify the orientation of the tensor fold while maintaining ossicular chain continuity.

    Endoscopic third ventriculostomy (ETV) is a safe and effective treatment for hydrocephalus. An entry point located 4 cm anterior to the coronal suture, 3 cm anterior to Kocher point, and approximately 9 cm from the pupil at the midpupillary line has been used successfully for the last 20 years in our center. We aimed to evaluate this alternative anterior entry point routinely used for ETV, with or without concurrent endoscopic biopsy. Patients undergoing this proposed entry point were examined to evaluate its safety and efficacy. Factors such as patients' age, sex, hydrocephalus etiology, tumor location and pathology, and complication rate were examined through regression analyses to evaluate their impact on tumor biopsy and ETV success rates, and the need for subsequent ventricular shunting. A total of 131 patients were included in the study. ETV was successful in 125 (95.4%) patients. Of these, 26 (19.8%) patients required a biopsy, which was successful in 21 (80.8%) cases. A complication was observed in 10 (7.6%) patients, with a trend toward complications occurring after ETV failure. There was no association between ETV success rate and patients' age (P = 0.5) or sex (P = 0.99). The anterior entry point is a safe and effective method for ETV, especially when considering concurrent ventricular tumor biopsy. This entry point may be considered as a more minimally invasive procedure when using rigid endoscopy and may also eliminate the need for a flexible scope. Copyright © 2017 Elsevier Inc.

    The purpose of this retrospective study is to determine the pattern of cerebrospinal fluid (CSF) rhinorrhoea presenting to our tertiary referral centre in Kuala Lumpur and to assess the clinical outcomes of endonasal endoscopic surgery for repair of anterior skull base fistulas. Sixteen patients were treated between 1998 and 2004. The aetiology of the condition was spontaneous in seven and acquired in nine patients. In the acquired category, three patients had accidental trauma and this was iatrogenic in six patients (five post pituitary surgery), with one post endoscopic sinus surgery (ESS). Imaging included computed tomography (CT) scan and magnetic resonance imaging (MRI). Endoscopic repair is less suited for defects in the frontal sinuses with prominent lateral extension and defects greater than 1.5 cm in diameter involving the skull base. Fascia lata, middle turbinate mucosa, nasal perichondrium and ear fat ('bath plug') were the preferred repair materials in the anterior skull base, whereas fascia lata, cartilage and abdominal fat obliteration was preferentially used in the sphenoid leak repair. Intrathecal sodium flourescein helped to confirm the site of CSF fistula in 81.3 per cent of the patients. Ninety per cent of the patients who underwent 'bath plug' repair were successful. The overall success rate for a primary endoscopic procedure was 87.5 per cent, although in two cases a second endoscopic procedure was required for closure. In the majority of cases endoscopic repair was successful, and this avoids many of the complications associated with craniotomy, particularly in a young population. Therefore it is our preferred option, but an alternative procedure should be utilized should this prove necessary.

    The conventional method for preventing web formation after anterior glottic web surgery is keel insertion. However, this presents risks of airway compromise and granulation tissue formation, which could necessitate tracheotomy in addition to a secondary procedure for keel removal. We introduce a novel, 1-stage endoscopic laser anterior commissurotomy for preventing anterior glottic web re-formation. Twenty patients with glottic webs involving the anterior commissure were studied. The lesions were removed by transoral carbon dioxide laser microsurgery. In all patients, the anterior glottic web was vaporized along with the inner perichondrium of the thyroid cartilage over the anterior commissure area, creating a raw vertical break "alley" between the anterior vocal folds that measured between 0.3 and 0.5 cm in width and between 0.8 and 2 cm in length. The preoperative and postoperative vocal folds and voice quality were evaluated by videostrobolaryngoscopy and voice recordings. All 20 patients had anterior glottic webs ranging from 11% to 64% of the length from the anterior commissure to the vocal process. None of the patients developed restenosis at the anterior commissure of a severity similar to that of the initial lesion during follow-up (mean, 13 months; range, 3 to 44 months).All patients except 1 reported satisfaction with their voice improvement. Outcome analysis revealed that partial re-formation of the web was noted in 4 patients. One-stage, endoscopic laser anterior commissurotomy was effective and relatively safe for removing glottic webs, for preventing anterior glottic web re-formation, and for improving vocal fold performance among our patients.

    Full Text Available Objective: To explore the effect of advanced blood pressure control with nifedipine delayedrelease tablets on the blood pressure in patients underwent nasal endoscope surgery and its feasibility. Methods: A total of 80 patients who were admitted in ENT department from June, 2012 to June, 2015 for nasal endoscope surgery were included in the study and randomized into the observation group and the control group with 40 cases in each group. The patients in the observation group were given nifedipine delayed-release tablets for advanced blood pressure control before operation, and were given routine blood pressure control during operation; while the patients in the control group were only given blood pressure control during operation. The changes of blood pressure, mean central arterial pressure, and heart rate before anesthesia (T0, after intubation (T1, during operation (T2, extubation when waking (T3, 30 min after extubation (T4, and 3 h after back to wards (T5 in the two groups were compared. The intraoperative situation and the surgical field quality in the two groups were compared. Results: SBP, DBP, and MAP levels at T1-5 in the two groups were significantly lower than those at T0. SBP, DBP, and MAP levels at T2 were significantly lower than those at other timing points, and were gradually recovered after operation, but were significantly lower than those at T0. The effect taking time of blood pressure reducing, intraoperative nitroglycerin dosage, and postoperative wound surface exudation amount in the observation group were significantly less than those in the control group. The surgical field quality scores in the observation group were significantly superior to those in the control group. Conclusions: Advanced blood pressure control with nifedipine delayed-release tablets can stabilize the blood pressure during the perioperative period in patients underwent nasal endoscope surgery, and enhance the surgical field qualities.

    Nonoperative management for patients with rectal cancer who have achieved a clinical complete response after chemoradiotherapy is becoming increasingly important in recent years. However, the definition of and modality used for patients with clinical complete response differ greatly between institutions, and the role of endoscopic assessment as a nonoperative approach has not been fully investigated. This study aimed to investigate the ability of endoscopic assessments to predict pathological regression of rectal cancer after chemoradiotherapy and the applicability of these assessments for the watchful waiting approach. This was a retrospective comparative study. This study was conducted at a single referral hospital. A total of 198 patients with rectal cancer underwent preoperative endoscopic assessments after chemoradiotherapy. Of them, 186 patients underwent radical surgery with lymph node dissection. The histopathological findings of resected tissues were compared with the preoperative endoscopic findings. Twelve patients refused radical surgery and chose watchful waiting; their outcomes were compared with the outcomes of patients who underwent radical surgery. The endoscopic criteria correlated well with tumor regression grading. The sensitivity and specificity for a pathological complete response were 65.0% to 87.1% and 39.1% to 78.3%. However, endoscopic assessment could not fully discriminate pathological complete responses, and the outcomes of patients who underwent watchful waiting were considerably poorer than the patients who underwent radical surgery. Eventually, 41.7% of the patients who underwent watchful waiting experienced uncontrollable local failure, and many of these occurrences were observed more than 3 years after chemoradiotherapy. The number of the patients treated with the watchful waiting strategy was limited, and the selection was not randomized. Although endoscopic assessment after chemoradiotherapy correlated with pathological response

    Full Text Available Background The current study aimed to evaluate the postural control in patients underwent anterior cruciate ligament reconstruction pre and post wearing functional knee brace. Methods Eighteen athletes undergone unilateral anterior cruciate ligament reconstruction included in the study. They had unilateral anterior cruciate ligament reconstruction at least six months before session test. Postural control was assessed pre and post wearing custom-fit functional knee brace using a posturographic platform prokin 254. The balance tests included: 1 standing on prokin platform with eyes open/closed on anterior cruciate ligament reconstruction limb, 2 standing on prokin platform with eyes open/closed on both limbs. The standard deviation (SD of body sway along the anteroposterior (AP and mediolateral (ML axis, mean velocity of center of pressure (COP along AP/ ML axis and the area ellipse (measured in 2 mm were calculated. Results Results of the paired T-test revealed a significant effect on selected postural control variables for the brace conditions especially in low challengeable conditions (double leg, eyes open test situations (P < 0.05. But in high challengeable conditions this effect was not significant. Conclusions Functional knee brace improved postural control in the simple balancing task in the subjects with anterior cruciate ligament reconstruction. But this improvement in more difficult balancing task was limited.

    The objective of this study was to review the endoscopic anatomy of the anterior skull base, defining the pitfalls of endoscopic endonasal approaches to this region. Recently, these approaches are gaining popularity among neurosurgeons, and the details of the endoscopic anatomy and approaches are highlighted from the neurosurgeons' point of view, correlated with demonstrative cases. Twelve fresh adult cadavers were studied (n = 12). We used Karl Storz 0 and 30 degrees, 4 mm, 18- and 30-cm rod lens rigid endoscope in our dissections. After preparation of the cadaveric specimens, we approached the anterior skull base by the extended endoscopic endonasal approach. After resection of the superior portion of the nasal septum, bilateral middle and superior turbinates, and bilateral anterior and posterior ethmoidal cells, we could obtain full exposure of the anterior skull base. The distance between optic canal and the posterior ethmoidal artery ranged from 8 to 16 mm (mean, 11.08 mm), and the distance between posterior ethmoidal artery and the anterior ethmoidal artery ranged from 10 to 17 mm (mean, 13 mm). After resecting the anterior skull base bony structure and the dura between the 2 medial orbital walls, we could visualize the olfactory nerves, interhemispheric sulcus, and gyri recti. With dissecting the interhemispheric sulcus, we could expose the first (A1) and second (A2) segments of the anterior cerebral artery, anterior communicating artery, and Heubner arteries. This study showed that extended endoscopic endonasal approaches are sufficient in providing wide exposure of the bony structures, and the extradural and intradural components of the anterior skull base and the neighboring structures providing more controlled manipulation of pathologic lesions. These approaches need specific skill and learning curve to achieve more minimally invasive interventions and less postoperative complications.

    Full Text Available Introduction: Quality of life can be defined as the expression of aconceptual model that tries to represent patient’s perspectivesand his/her level of satisfaction expressed by numbers. Theobjective of this study is to evaluate the parameters of quality oflife of 23 patients who underwent surgery for anterior cruciateligament reconstruction. Methods: We adopted SF-36, a generichealth-related evaluation questionnaire, to obtain informationregarding several aspects of patients’ health conditions, and theLysholm questionnaire, specific to evaluate the symptoms andfunction of the knee. The questionnaires were applied at two stagesof the treatment: pre- and postoperatively (after the rehabilitationprogram. Results: Before surgery, the Lysholm questionnairepresented the following results: excellent in 4% of the cases, goodin 22%, fair in 22%, and poor in 52%. After surgery (Lysholm e SF-36 the correlation level was approximately 44% (p = 0.041.Discussion: The correlation between the Lysholm and the SF-36questionnaires showed the following: the lower the level of pain,the higher the Lysholm score. The high scores presented by theLysholm questionnaire are directly proportional to physical andemotional aspects, and to functional capacity. Conclusion:Analysis of both questionnaires, as well as of their correlation,showed some improvement in patients´ quality of life. We werealso able to demonstrate the importance and usefulness of applyingthe two questionnaires at three different moments: before, duringand after physiotherapeutic intervention.

    Aneurysms of the anterior pontine segment of the anterior-inferior cerebellar artery (AICA) are uncommon. Their treatment is challenging because critical neurovascular structures are adjacent to it and the available surgical corridors are narrow and deep. Although endoscopic endonasal approaches are accepted for treating midline skull base lesions, their role in the treatment vascular lesions remains undefined. The present study is aimed to assess the anatomic feasibility of the endoscopic endonasal transclival (EET) approach for treating anterior pontine AICA aneurysms and compare it with the subtemporal anterior transpetrosal (SAT) approach. Twelve cadaveric specimens were prepared for surgical simulation. The AICAs were exposed using both EET and SAT approaches. Surgical window area and the length of the exposed artery were measured. The distance from the origin of the artery to the clip applied for proximal control was measured. The number of AICA perforators exposed and the anatomic features of each AICA were recorded. The EET approach provided a wider surgical window area compared with the SAT (P AICA perforators were visualized using the EET approach (P AICA, an aneurysm clip could be applied closer to the origin of AICA using EET (0.2 ± 0.42 mm) compared with SAT (6.26 ± 3.4 mm) (P AICA aneurysms using the EET approach is feasible. Compared with SAT, the EET approach provides advantages in surgical window area, ensuring proximal control before aneurysm dissection, visualization of perforating branches, and better proximal control.

    2014-06-01

    Conclusion: To the best of our knowledge, ours is the only case of a dermoid cyst anchored to the anterior optic chiasma, which was visually confirmed under endoscopic observation. After surgery, the patient presented a transient impairment of the visual field, which was not evident at four month follow-up. It will contribute to a similar case, in which surgeons hesitate to make an incision in the optic chiasm. A subtotal excision should be considered in cases of dermoid cysts anchored to the anterior optic chiasm, because all the previously reported cases of suprasellar dermoid cysts are young people or those who have a relatively long life expectancy.

    Studies describing the efficacy of TPED on shortness of recovery and improvement of postoperative quality of life are limited, especially regarding gender something that has never been reported before in the literature. The purpose of this study is to evaluate possible differences of the health-related quality of life in patients who underwent TPED for LDH in accordance with sex. Seventy-six patients diagnosed and treated with TPED for LDH with 1 year follow-up were selected and divided into two groups of equal number depending on sex. Their quality of life was evaluated by using the SF-36 before the operation, six weeks, three, six and twelve months postoperatively. A statistical analysis was conducted, in order to compare the 8 scaled scores of the SF-36 combining each time two chronological phases in the total of patients, in each group and between groups. Fifty-two (68.4%) patients were ≤63 years old, while the rest 24 (31,4%) were >63 years old (mean ±SD = 56,5 ±12,1 years). Apart from the PF domain, the scores were higher in every visit for the two groups, but the change between groups was not significant. Women had a significantly higher increase of PF score in 3 months after TPED and in the interval 6 weeks-3 months comparing with men. However, in the intervals 3 months-6 months and 3 months-12 months men presented significantly higher increase compared to women. Statistically significant improvement of the quality of life for both men and women was observed. Generally, there was no significant difference between the two groups. As regards to the physical functioning, it appears to be a significant difference which is counterpoised over time. 2. TPED for LDH does not present major differences in the improvement of quality of life regarding gender.

    2014-04-01

    Full Text Available [english] Background: A tremendous number of free flaps have been developed in the past. As the surgical result depends not only on a successful flap transfer but also on the harvest, this paper details the procedures for undertaking the first total endoscopic harvest of a serratus fascia flap for free flap transplantation to the lower leg. Patient and methods: In September 2012 we performed the first total endoscopic serratus anterior fascia free flap harvest. The incision of 2.5 cm length was made 10 cm in front of anterior muscle border of the latissimus dorsi at level with the midthorax. After insertion of a flexible laparoscopic single port system we started CO gas insufflation. We used this setting to meticulously prepare a neo cavity between atissimus dorsi and M. serratus anterior. The vessels were dissected and the thoraco-dorsal nerve was separated. With a second auxiliary incision we used a clamp to support the raising of the fascia flap from the underlying muscle. Finally we clipped the vessels to the latissimus dorsi muscle and the flap vessels at the Arteria and Vena axillaris. The flap was extracted via the 2.5 cm incision.Results: We were able to perform a total endoscopic harvest of a serratus fascia flap for free flap reconstruction of soft tissues. With this new operative technique we were able to avoid a long skin incision, which in our view lowers the morbidity at the harvest area.Conclusion: We describe a new method for the total endoscopic harvest of the serratus fascia flap for free flap transfer. The flap was harvested within reasonable time and following surgery leaves the patient with minimal donor site morbidity compared to the open technique.

    Full Text Available Introduction: The supraorbital keyhole approach for anterior cranial base lesions has been increasingly used in clinical practice. Anatomical studies focusing on the endoscopic anatomy via this approach are few, although the microscopic anatomy has been well studied. The aim of this study is to describe the anatomical features and surgical exposure provided by the endoscopic supraorbital keyhole approach using quantitative measurements. Materials and Methods: Nine formalin-fixed human cadavers from the inventory of the Anatomy department were used. A total of 18 supraorbital keyhole cranitomies were conducted. The distances between the target anatomical structures and the dura mater at the craniotomy site, and the distances between deep anatomical structures were measured with purpose-designed hooks. Results: The distance between the dura mater and optic canal was measured as 69.5 ± 6.7 mm (62-83 mm; optic chiasm as 76.2 ± 5.4 mm (67-86 mm; anterior communicating artery as 82.6 ± 6.1 mm (71-93 mm; internal carotid artery (ICA bifurcation as 74.7 ± 6.0 mm (66-84 mm and the basilar tip as 94.9 ± 7.0 mm (87-111 mm. The mean diameter of the optic canal was 7.4 ± 1.3 mm (6-11 mm, whereas the mean diameter of diaphragma sellae was measured as 8.4 ± 1.1 mm (7-10 mm. Conclusions: The results of this study showed that the anterior anda medial aspects of the anterior cranial fossa can be visualized properly. Dissection of the ipsilateral arteries of Circle of Willis can be performed easily using an endoscopic supraorbital keyhole approach.

    This work is a retrospective analysis to investigate the critical risk factor for the therapeutic effect of endoscopic keel placement on anterior glottic web. Altogether, 36 patients with anterior glottic web undergoing endoscopic lysis and silicone keel placement were enrolled. Their voice qualities were evaluated using the voice handicap index-10 (VHI-10) questionnaire, and improved significantly 3 months after surgery (21.53 ± 3.89 vs 9.81 ± 6.68, P web recurrence during the at least 1-year follow-up. Therefore, patients were classified according to the Cohen classification or web thickness, and the recurrence rates were compared. The distribution of recurrence rates for Cohen type 1 ~ 4 were 28.6, 16.7, 33.3, and 40%, respectively. The difference was not statistically significant (P = 0.461). When classified by web thickness, only 2 of 27 (7.41%) thin type cases relapsed whereas 8 of 9 (88.9%) cases in the thick group reformed webs (P web thickness rather than the Cohen grades. Endoscopic lysis and keel placement is only effective for cases with thin glottic webs. Patients with thick webs should be treated by other means.

    Although the pepsinogen I/II (PGI/II) ratio after Helicobacter pylori eradication is recovered at short-term follow-up, long-term follow-up studies of PGI/II are rare. A total of 773 patients with gastric cancer who underwent endoscopic resection and pepsinogen and H. pylori tests were enrolled. H. pylori was eradicated in these patients. Endoscopic and pepsinogen tests were performed every year. A low PGI/II ratio was defined as ≤3. The PGI/II ratio was higher in non-infected patients (n=275, 4.99) than infected patients (n=498, 3.53). After H. pylori eradication, the PGI/II ratio increased to 5.81 and 5.63 after 1 and 2 years (each ppylori eradication group became similar to that of the H. pylori-negative group at 3 (4.48 vs. 4.34), 4 (4.88 vs. 4.34), and 5 years (4.89 vs. 4.23). The adjusted odds ratios for a lower PG I/II ratio in the non-eradication group compared to the eradication group were 4.78 (95% CI 2.15-10.67) after 1year and 8.13 (95% CI 2.56-25.83) after 2 years. After H. pylori eradication, the PGI/II ratio increased and was similar to that of H. pylori-negative controls for up to 5 years of follow-up.

    The anterior ethmoidal artery (AEA) is an important point of anatomical reference in order to locate the frontal sinus and the skull base. Notwithstanding, despite numerous endoscopic studies in cadavers, we still lack an anatomical study on the AEA in the western population. to determine reference points used to locate the artery, study its relationship with the skull base and its degree of dehiscence, as well as to study intra and inter individual variations. we dissected the nasal fossae belonging to 25 cadavers. the average intranasal length of the anterior ethmoidal artery was 5.2 mm. The anterior ethmoidal canal presented some degree of dehiscence in 66.7%. The average distance between the artery middle point to the anterior nasal spine was of 61.72 mm (sd=4.18 mm); to the lateral nasal wall (nasal axilla) was of 64.04 mm (sd=4.69 mm); and from the anterior axilla to the middle turbinate was of 21.14 mm (sd=3.25 mm). For all the measures there was no statistically significant measures when both sides were compared (p>0.05). We concluded that the middle conchae axilla is the most reliable point of reference to locate the AEA.

    As a bridge between open and percutaneous therapy, endoscopy of the cervical spine started to be used at the beginning of the 1990s, following good experiences on the lumbar spine. The principle of microsurgery is combined with the minimally invasive principles by bringing the optical level to the forefront of pathology. Access morbidity has been significantly reduced by the percutaneous access technique. However, this procedure cannot be applied in patients with cervical disc herniation accompanied by segmental instability.In further developing these endoscopic techniques, in view of the experiences with the classical "Cloward procedure", the aim was to do a bony fusion of the intervertebral space of the cervical spine by endoscopic access. A female patient with postraumatic instability of the cervical segments C4/5 underwent a fullendoscopic bony fusion. The technique will be described. The fusional process has been documented by CT and clinical assessment over 3 months. Having preoperative pain of VAS 8, it diminished to VAS 1 after surgery. The Ct-controls demonstrated a good placement of the bony dowel through the endoscopic sheath in the intervertebral space. After 3 months a bony fusion was documented by CT and in bending X-ray. The result of this method displays that a fullendoscopic fusion of the cervical spine with a bone dowel is possible. The clinical result seems to be comparable to the classical Cloward procedure. To the best of my knowledge, this is the first report of a fullendoscopic osseous fusion on the cervical spine.

    Conservative treatment of anastomotic leakage after anterior resection of the rectum seems to be possible in patients who have no occurrence of generalized peritonitis. This report describes a new method of endoscopic management of large anastomotic leakage in these patients. The main feature of this new method is the endoscopically assisted placement of an open-cell sponge connected to a vacuum device into the abscess cavity via an introducer device. The sponge system is changed every 48-72 h. Twenty-nine patients with an anastomotic leakage after anterior resection were treated with the endoscopic vacuum therapy. The total duration of endovac therapy was 34.4 +/- 19.4 days. The total number of endoscopic sessions per patient was 11.4 +/- 6.3. In 21 of the 29 patients, a protecting stoma was created at the primary operation. Four patients were treated successfully without the need of a secondary stoma. Definitive healing was achieved in 28 of the 29 patients. Endoscopic vacuum-assisted closure is a new efficacious modality for treating anastomotic leakage following anterior resection due to an effective control of the septic focus. Further studies will show if it is possible to reduce the high mortality rate of patients with anastomotic leakage through the avoidance of surgical reinterventions while at the same time preserving the sphincter function.

    Corpus callosotomy and hemispherotomy are conventionally performed via a large craniotomy with the aid of a microscope for children with intractable epilepsy. Primary technical considerations include completeness of disconnection and blood loss. The authors describe an endoscopic technique performed through a microcraniotomy for these procedures. Four patients with drop attacks and 2 with intractable seizures related to a neonatal stroke underwent endoscopic complete corpus callosotomy and hemispherotomy, respectively. The surgeries were performed through a 2- to 3-cm precoronal microcraniotomy. Interhemispheric dissection to the corpus callosum was done using the standard technique. Subsequently, the bimanual technique with a suction device mounted on an endoscope was used to perform a complete corpus callosotomy, including interforniceal and anterior commissure disconnection. In patients who had hemispherotomy, the fornix was resected posteriorly and lateral disconnection was done by unroofing the temporal horn. Anteriorly, endoscopic corticectomy was done along the ipsilateral anterior cerebral artery to reach the bifurcation of the internal carotid artery to complete the anterior disconnection. Postoperative MRI and diffusion tensor imaging (DTI) of the brain were performed to confirm complete disconnection. The procedure was accomplished successfully in all patients, with excellent visualization secured. None of the patients required a blood transfusion. Postoperative MRI and DTI confirmed completeness of the disconnection. Patients who underwent corpus callosotomy had complete resolution of drop attacks at a mean follow-up of 6 months, and patients who underwent hemispherotomy became seizure free. Endoscopic corpus callosotomy and hemispherotomy are surgically feasible procedures associated with minimal blood loss, minimal risk, and excellent visualization.

    We recently described early rigid retrograde endoscopic realignment of the disrupted urethra under caudal anaesthesia in the outpatient setting. This retrospective study was performed to evaluate our medium-term results. A retrospective review of patients who had early rigid retrograde endoscopic realignment of traumatic urethral disruptions in our institution over a 5-year period was done and the relevant data extracted and analyzed. Fourteen acutely ruptured urethras (10 posterior and four anterior) were endoscopically realigned early in the study period. Nine (90%) of the posterior disruptions occurred at bulbo-membranous urethra (distal to the external sphincter mechanism). Thirteen of the ruptured urethras (93%) were successfully realigned (nine posterior and four anterior) and postoperative clean intermittent self-calibration (CIC) was instituted in 10 patients. The mean follow-up period was 36.6 months (range 18-54 months). The mean operating time and the median hospital stay were 22 min (range 8-68 min) and 3 days (range 1-10 days), respectively, and were shorter in patients with injuries of the anterior urethra than those with posterior urethral tears (p < or = 0.0001). Post-realignment, all 13 patients were potent and continent. Two patients required additional procedures (direct vision internal urethrotomy or urethral dilation) and one patient has remained on CIC i.e. a stricture rate of 21%. Early retrograde endoscopic realignment under caudal analgesia is suitable and cost-effective for patients with acute traumatic urethral disruptions and has good medium-term results. In addition, an early postoperative regimen of CIC significantly reduced stricture-formation in our series.

    Objective  To determine the volume of ventral skull base tumor removed following endoscopic endonasal (EEA) resection using MRI-based volumetric analysis and to evaluate the inter-rater reliability of such analysis. Design  Retrospective case series. Setting  Academic tertiary care hospital. Participants  EEA patients November 2012 to August 2015. Main Outcome Measures  Volumetric analysis of pre- and immediately postoperative MR imaging was performed independently by two investigators. The percentage of total tumor resected was evaluated according to resection goal and tumor type. Results  A total of 39 patients underwent resection. Intraclass correlation coefficients between the raters were 0.9988 for preoperative and 0.9819 for postoperative images. Tumors (and average percentage removed) included 17 nonsecreting pituitary adenomas (95.3%), 8 secreting pituitary adenomas (86.2%), 4 meningiomas (81.6%), 3 olfactory neuroblastomas (100%), 2 craniopharyngiomas (100%), 1 large B-cell lymphoma (90.5%), 1 germ cell neoplasm (48.3), 1 benign fibrous connective tissue mass (93.4%), 1 epidermoid cyst (68.4%), and 1 chordoma (100%). For tumors treated with intent for gross total resection, 96.9 ± 4.8% was removed. Conclusion  EEAs achieved tumor resection rates of ∼97% when total resection was attempted. The radiographic finding of residual tumor is of uncertain clinical significance. The volumetric analysis employed in this study demonstrated high inter-rater reliability and could facilitate further study.

    The endoscopic endonasal transcribriform approach (EETA) is a viable alternative option for resection of selected anterior skull base (ASB) tumors. However, this technique results in the creation of large cribriform defects. Some have reported the use of a rigid substitute for ASB reconstruction to prevent postoperative frontal lobe sagging. We evaluate the degree of frontal lobe sagging using our triple-layer technique [fascia lata, acellular dermal allograft, and pedicled nasoseptal flap (PNSF)] without the use of rigid structural reconstruction for large cribriform defects. Retrospective analysis. Nine patients underwent an EETA for resection of large ASB tumors from August 2010 to November 2011. The degree of frontal lobe displacement after EETA, defined as the ASB position, was calculated based on the most inferior position of the frontal lobe relative to the nasion-sellar line defined on preoperative and postoperative imaging. A positive value signified upward displacement, and a negative value represented inferior displacement of the frontal lobe. The average cribriform defect size was 9.3 cm(2) (range, 5.0-13.8 cm(2) ). The average distance of postoperative frontal lobe displacement was 0.2 mm (range, -3.9 to 2.9 mm) without any cases of significant brain sagging. The mean follow-up period was 10.1 months (range, 4-19 months). There were no postoperative CSF leaks. Rigid structural repair may not be necessary for ASB defect repair after endoscopic endonasal resection of the cribriform plate. Our technique for multilayer cranial base reconstruction appears to be satisfactory in preventing delayed frontal lobe sagging.

    Full Text Available CONTEXT: For the diagnosis of the diseases which affect the terminal ileum, the colonoscopy allows macroscopic evaluation and the performing of biopsies. Studies with criteria for the endoscopic and histological characterization of this segment are scarce and there are still some doubts about the need of biopsies in patients with normal ileoscopy. OBJECTIVE: Study the terminal ileum of patients who underwent colonoscopy considering: endoscopic and histological correlation; agreement between results of the initial histological evaluation and slides review, and the chance of subjects with normal ileoscopy with abdominal pain and/or chronic diarrhea to show histological alterations. METHODS: In a prospective study, 111 patients who presented smooth mucosa without enanthema in the endoscopic exam of the terminal ileum were selected. Biopsies of the ileal mucosa of such patients were performed, being the slides routinely examined and reviewed afterwards. RESULTS: The correlation between patients with normal ileoscopy and ileum with preserved histological architecture was of 99.1%. The agreement between initial histological evaluation and slides review calculated by the Kappa test was 0.21. In patients with abdominal pain and/or chronic diarrhea, the chance of showing histological alterations was 2.5 times higher than the others. CONCLUSIONS: The correlation between endoscopic and histological findings was high. The agreement between the initial histologic evaluation and slides review was not satisfactory. The chance of subjects with normal ileoscopy with abdominal pain and/or chronic diarrhea, showing histological alterations was higher in relation to the asymptomatic ones or with other symptoms, although the clinical importance of this datum was not evaluated.CONTEXTO: Para o diagnóstico de doenças que afetam o íleo terminal, a colonoscopia permite avaliação macroscópica e realização de biopsias.

    To report our 12-year experience with endoscopic management of patients with concomitant anterior and posterior urethral valves. We retrospectively reviewed the charts of patients referred to us for management of urethral valves from 2000 to 2012 to find cases with concomitant anterior and posterior valves. The diagnosis of valves was first suspected on voiding cystourethrography and confirmed by urethrocystoscopy. We collected available data on patients' age at diagnosis, clinical presentations, ultrasound and urodynamic findings, and surgical treatments. The final outcome at last follow up was also recorded. From 38 cases with anterior urethral valve, six (15.8%) presented concomitant anterior and posterior valves. The age at diagnosis in these patients ranged from antenatal diagnosis to 13 years. Initial presenting symptoms were recurrent urinary tract infection, incontinence, urosepsis and poor urinary stream. All valves were ablated by transurethral fulguration/resection using small-sized urethrocystoscopes. Among those with concomitant anterior and posterior valves, four patients had vesicoureteral reflux at presentation that resolved in two patients after valve ablation. One patient progressed to renal failure and required dialysis. Bladder hypercontractility and detrusor overactivity were the main urodynamic patterns in these patients. Concomitant anterior and posterior valves seem to be more prevalent than previously assumed, and might be missed on initial assessment. Oblique view voiding cystourethrography with full-length delineation of the urethra is of paramount diagnostic importance when obstruction is suspected. A meticulous urethrocystoscopy should follow for confirming the diagnosis and endoscopic ablation/resection of the valves. © 2015 The Japanese Urological Association.

    With the continuous development of the spinal endoscopic technique in recent years, percutaneous endoscopic cervical discectomy (PECD) has emerged, which bridges the gap between conservative therapy and traditional surgery and has been mainly divided into the anterior transdiscal approach and the posterior interlaminar access. Because of the relatively greater violation to the anterior nucleus pulposus, there is a higher potential of postoperative intervertebral space decrease in the anterior transdiscal approach than in the posterior interlaminar access. In addition, when the herniated lesion is migrated upward or downward behind the vertebral body, both approaches, and even anterior cervical discectomy and fusion, are impractical, and corpectomy is commonly considered as the only efficacious treatment. Anterior transcorporeal approach under endoscopy could enable an individual and adjustable trajectory within the vertebral body under different conditions of disc herniation preserving the motion of adjacent segment, especially in a migrated or sequestered lesion. This report aimed to first describe a novel anterior transcorporeal approach under endoscopy in which we addressed a migrated disc herniation at the C4-C5 levels. A technical report was carried out. A 37-year-old woman presented with posterior neck pain and weakness of extremities for 9 months. On neurologic examination, tingling sensation and numbness were not obvious. However, the power of extremities was dramatically decreased at a level of 3. Hoffmann sign was positive in the bilateral hand. Magnetic resonance imaging (MRI) showed a huge herniation of the C4-C5 disc compressing the median area of the spinal cord. Besides the C4-C5 disc herniation, preoperative computer tomography (CT) also detected that the herniated disc had partial calcification. A novel anterior transcorporeal approach of PECD, through the vertebral body of C5, was performed to address a migrated disc herniation at the C4-C5 levels

    Long-term prospective studies of isolated endoscopic anterior cruciate ligament (ACL) reconstruction are limited and may include confounding factors. This study aimed to compare the outcomes of isolated ACL reconstruction using the patellar tendon (PT) autograft and the hamstring (HT) autograft in 180 patients over 20 years. Cohort study; Level of evidence, 2. A total of 180 participants undergoing isolated ACL reconstruction between 1993 and 1994 were prospectively recruited. Evaluation was performed at 1, 2, 5, 7, 10, 15, and 20 years after surgery and included the International Knee Documentation Committee (IKDC) knee ligament evaluation with radiographic evaluation, KT-1000 arthrometer side-to-side difference, and subjective scores. Over 20 years, there were 16 patients (18%) and 9 patients (10%) with an ACL graft rupture in the HT and PT groups, respectively (P = .13). ACL graft rupture was associated with male sex (odds ratio [OR], 3.9; P = .007), nonideal tunnel position (OR, 3.6; P = .019), and age <18 years at the time of surgery (OR, 4.6; P = .003). The odds of a contralateral ACL rupture were increased in patients with the PT graft compared with patients with the HT graft (OR, 2.2; P = .02) and those aged <18 years at the time of surgery (OR, 3.4; P = .001). The mean IKDC scores at 20-year follow-up were 86 and 89 for the PT and HT groups, respectively (P = .18). At 20 years, 53% and 57% of the PT and HT groups participated in strenuous or very strenuous activities (P = .55), kneeling pain was present in 63% and 20% of the PT and HT groups (P = .018), and radiographic osteoarthritic change was found in 61% and 41% of the PT and HT groups (P = .008), respectively. Compared with patients who received the HT graft, patients who received the PT graft had significantly worse outcomes with regard to radiologically detectable osteoarthritis, kneeling pain, and contralateral ACL injury. At 20-year follow-up, both HT and PT autografts continued to provide good

    Recent advancements in transnasal endoscopy enable a shift in diagnostic workup of lesions in the pharynx and larynx, from an examination with biopsy under general anesthesia to an office-based examination with flexible endoscopic biopsy under topical anesthesia. Procedural complications were evaluated to assess the safety of office-based flexible endoscopic biopsy in patients with benign and malignant laryngopharyngeal lesions. Patients who underwent flexible endoscopic biopsy from 2012 to 2016 were evaluated retrospectively. Complications were classified using the Clavien-Dindo classification of surgical complications. A total of 201 flexible endoscopic biopsies were performed in 187 patients. Two Clavien-Dindo grade I (laryngospasm and anterior epistaxis), one grade II (laryngeal bleeding), and one grade IIIb (laryngeal edema) complication were observed. The first complication was self-limiting and the other three required an intervention. All patients fully recovered without sequelae. Flexible endoscopic biopsy appears to be a safe office-based procedure for the diagnosis of benign and malignant laryngopharyngeal lesions.

    Prat, Ricardo; Galeano, Inmaculada

    2009-09-01

    To describe our institution experience regarding the usefulness and limitations of frameless neuronavigation in the endoscopic biopsy of foramen of Monro and third ventricle lesions. We report our experience with 22 patients harbouring intraventricular lesions located in the region of the foramen of Monro or the third ventricle who underwent endoscopic biopsy guided by the neuronavigation system. Nine lesions were located on the posterior aspect of the third ventricle or at the pineal region, and thirteen lesions were located at the foramen of Monro or anterior third ventricle region. The endoscopes were introduced via an operating sheath, which had previously been inserted with a trocar under neuronavigational control. After approaching the foramen of Monro from the planned angle, surgery was continued under direct visualisation until the lesion was reached, if it was located on the third ventricle. In cases where the lesion was located at the foramen of Monro, an excellent view of the lesion was obtained and neuronavigation was used to determine the location of critical areas. Histological examination of biopsy specimens obtained endoscopically was diagnostic in all cases. Open surgery following endoscopic biopsy was only needed in 1 patient out of 22. In our experience, image-guided neuroendoscopy can improve the accuracy of the endoscopic approach, minimising brain trauma. It can be particularly helpful when performing a brain biopsy in the absence of clear intraventricular landmarks or in the event of adverse visual conditions such as intraventricular bleeding.

    The objective of this study was to evaluate the technical aspects and clinical efficacy of selective embolization for post-endoscopic sphincterotomy bleeding. We reviewed the records of 10 patients (3%; M:F 6:4; mean age, 63.3 years) that underwent selective embolization for post-endoscopic sphincterotomy bleeding among 344 patients who received arteriography for nonvariceal upper gastrointestinal bleeding from 2000 to 2009. We analyzed the endoscopic procedure, onset of bleeding, underlying clinical condition, angiographic findings, interventional procedure, and outcomes in these patients. Among the 12 bleeding branches, primary success of hemostasis was achieved in 10 bleeding branches (83%). Secondary success occurred in two additional bleeding branches (100%) after repeated embolization. In 10 patients, post-endoscopic sphincterotomy bleedings were detected during the endoscopic procedure (n = 2, 20%) or later (n = 8, 80%), and the delay was from one to eight days (mean, 2.9 days; {+-} 2.3). Coagulopathy was observed in three patients. Eight patients had a single bleeding branch, whereas two patients had two branches. On the selective arteriography, bleeding branches originated from the posterior pancreaticoduodenal artery (n = 8, 67%) and anterior pancreaticoduodenal artery (n = 4, 33%), respectively. Superselection was achieved in four branches and the embolization was performed with n-butyl cyanoacrylate. The eight branches were embolized by combined use of coil, n-butyl cyanoacrylate, or Gelfoam. After the last embolization, there was no rebleeding or complication related to embolization. Selective embolization is technically feasible and an effective procedure for post-endoscopic sphincterotomy bleeding. In addition, the posterior pancreaticoduodenal artery is the main origin of the causative vessels of post-endoscopic sphincterotomy bleeding.

    To demonstrate the importance of pre-operative ear, nose and throat assessment in patients undergoing endoscopic, transsphenoidal surgery for pituitary tumours. Literature pertaining to the pre-operative otorhinolaryngological assessment and management of patients undergoing endoscopic anterior skull base surgery is sparse. We describe two cases from our series of 59 patients undergoing endoscopic pituitary surgery. The first case involved a young male patient with a large pituitary macroadenoma. His main complaint was visual impairment. He had no previous history of sinonasal pathology and did not complain of any nasal symptoms during the pre-operative neurosurgical assessment. At the time of surgery, a purulent nasal discharge was seen emanating from both middle meati. Surgery was abandoned due to the risk of post-operative meningitis, and postponed until the patient's chronic rhinosinusitis was optimally managed. The second patient was a 47-year-old woman with a large pituitary macroadenoma, who presented to the neurosurgical department with a main complaint of diplopia. She too gave no history of previous nasal problems, and she underwent uneventful surgery using the endoscopic, transnasal approach. Two weeks after surgery, she presented to the emergency unit with severe epistaxis. A previous diagnosis of hereditary haemorrhagic telangiectasia was discovered, and further surgical and medical intervention was required before the epistaxis was finally controlled. Pre-operative otorhinolaryngological assessment is essential prior to endoscopic pituitary or anterior skull base surgery. A thorough otorhinolaryngological history will determine whether any co-morbid diseases exist which could affect the surgical field. Nasal anatomy can be assessed via nasal endoscopy and sinusitis excluded. Computed tomography imaging is a valuable aid to decisions regarding additional procedures needed to optimise access to the pituitary fossa.

    to investigate the side effects and survival of endoscopic variceal ligation by using Indonesian Endoscopic Ligator versus Endoscopic Variceal Sclerotherapy. we studied the medical records and endoscopy reports of patients who underwent endoscopic variceal ligation (EVL) or endoscopic sclerotherapy (EST) from January 2003 until December 2006. EST was done using ethoxysclerol injection; and ligation was done using a home-made Indonesian endoscopic ligating device. Patient characteristics, side effects of EVL and EST, as well as survival and length of stay were collected. Data of side effects was analyzed by chi-square test. there were no statistically significant differences of patients characteristics among both groups. The side effects in EVL group (29.2%) were less frequent than the EST group (60.9%) (p = 0.009). The death side effect in the EVL group (1.0%) was less frequent than in the EST group (21.7%) (pEVL and EST were 91.7% and 16.7%, respectively (pEVL had fewer side effects than EST in the treatment of esophageal varices bleeding. Death in the EVL group was lower than in the EST group.

    Full Text Available Background/Aim. Intensive epiphora (lacrimal apparatus disease can make difficult daily routine and cause ocular refraction disturbances. In most cases ethiology is unknown, rarely occurs after nose surgical procedures, face fractures, in Wegener granulomatosis, sarcoidosis and malignancies. The aim of this study was to evaluate efficacy of endonasal endoscopic surgical procedure with the conventional surgical instruments in treatment of nasolacrimal obstructions. Methods. This retrospective study included 12 female patients with endonasal endoscopic surgical procedure from Otorhinological and Ophtalmological Departments of Military Medical Academy, Belgrade from September 2007 to April 2009. Preoperative nasal endoscopy was performed in order to reveal concomitant pathological conditions and anatomic anomalies which could make surgical procedure impossible. Computerized tomography was performed only in suspect nose diseases. Surgical endonasal endoscopic procedure was performed by otorhinolaryngologist and ophtalmologist in all patients. The patients had regular controls from 2 to 20 months. Results. A total of 12 female patients, age 34-83 years, were included in our study. Epiphora was a dominant symptom in all patients. In two patients deviation of nasal septum was found, and in other one conha bulosa at the same side as chronic dacryocystitis. All patients were subjected to endonasal dacryocystorhinostomy (DCR by endoscopic surgical technique using conventional instruments. Concomitantly with DCR septoplastics in two patients and lateral lamictetomy in one patient were performed. There were no complications intraoperatively as well as in the immediate postoperative course. In two patients the need for reoperation occurred. Conclusion. Endoscopic DCR is minimally invasive and efficacious procedure for nasolacrymal obstructions performed by otorhinolaryngologist and ophtalmologist. Postoperative recovery is very fast.

    Endoscopic sinonasal surgery is the procedure of choice in the treatment of chronic rhinosinusitis and sinonasal polyposis refractory to medical treatment, with high rates of success (76% to 97.5%). However, 2.5%-24% of those patients will require revision surgery (RESS). In this study, we present the clinical, anatomical, radiological and histological features of patients receiving RESS in our centre during a 3-year period. A retrospective review of clinical, anatomical, radiological and histopathological data of patients receiving revision endoscopic sinonasal surgery between 2012 and 2014 was carried out. From 299 surgery procedures performed, 27 (9%) were revision surgeries. The mean patient age was 46 years, with a male/female ratio of 1.4/1. The most frequent preoperative and postoperative diagnosis was chronic polypoid rhinosinusitis. The mean time since the previous surgery was 6.1 years, with 11.9 months of mean follow-up since that surgery. Stenotic antrostomy was found during revision in 81.5% of the patients and incomplete anterior ethmoidectomy and persistent uncinate process, in 59.3%. In radiology, 70.4% of patients had persistent anterior ethmoidal cells. Antrostomy or widening of antrostomy was performed in 96.3% of cases and anterior ethmoidectomy or completion of it was performed in 66.7%. Polyps, stenotic antrostomy and incomplete ethmoidectomy were the most frequent causes of revision surgery, in concordance with the procedures performed. The patients had long periods of time without follow-up between surgeries. Further investigation is necessary to generate measures to reduce the number of revision surgeries.

    Objective: Therapy for anterior combined with posterior urethral stricture is difficult and controversial. This study aims to introduce a standard process for managing anterior combined with posterior urethral stricture. Patients and methods: 19 patients with anterior combined with posterior urethral stricture were treated following our standard process. Average (range) age was 52 (21-72) years old. In this standard process, anterior urethral stricture should be treated first. Endoscopic surgery is applied for anterior urethra stricture as a priority as long as obliteration does not occur, and operation for posterior urethral stricture can be conducted in the same stage. Otherwise, an open reconstructive urethroplasty for anterior urethral is needed; while in this condition, the unobliterated posterior urethra can also be treated with endoscopic surgery in the same stage; however, if posterior urethra obliteration exists, then open reconstructive urethroplasty for posterior urethral stricture should be applied 2-3 months later. Results: The median (range) follow-up time was 25.8 (3-56) months. All 19 patients were normal in urethrography after 1 month of the surgery. 4 patients (21.1%) recurred urethral stricture during follow-up, and the locations of recurred stricture were bulbomembranous urethra (2 cases), bulbar urethra (1 case) and bladder neck (1 case). 3 of them restored to health through urethral dilation, yet 1 underwent a second operation. 2 patients (10.5%) complaint of dripping urination. No one had painful erection, stress urinary incontinence or other complications. Conclusions: The management for anterior combined with posterior urethral stricture following our standard process is effective and safe. PMID:26064293

    Full Text Available In vivo endoscopic optical microscopy provides a tool to assess tissue architecture and morphology with contrast and resolution similar to that provided by standard histopathology – without need for physical tissue removal. In this article, we focus on optical imaging technologies that have the potential to dramatically improve the detection, prevention, and therapy of epithelial cancers. Epithelial pre-cancers and cancers are associated with a variety of morphologic, architectural, and molecular changes, which currently can be assessed only through invasive, painful biopsy. Optical imaging is ideally suited to detecting cancer-related alterations because it can detect biochemical and morphologic alterations with sub-cellular resolution throughout the entire epithelial thickness. Optical techniques can be implemented non-invasively, in real time, and at low cost to survey the tissue surface at risk. Our manuscript focuses primarily on modalities that currently are the most developed: reflectance confocal microscopy (RCM and optical coherence tomography (OCT. However, recent advances in fluorescence-based endoscopic microscopy also are reviewed briefly. We discuss the basic principles of these emerging technologies and their current and potential applications in early cancer detection. We also present research activities focused on development of exogenous contrast agents that can enhance the morphological features important for cancer detection and that have the potential to allow vital molecular imaging of cancer-related biomarkers. In conclusion, we discuss future improvements to the technology needed to develop robust clinical devices.

    Full Text Available Neuroendocrine neoplasms of the gastric tube are less common than adenocarcinomas. Topography includes stomach, small intestine, Vater ampulla, and gross intestine. They are graded as neuroendocrine tumors grade I and II (NETs GI and GII and neuroendocrine carcinomas GIII based on Ki-67 index and mitotic count. [1] Endoscopic treatment for GI NETs ≤1 cm that does not extend beyond the submucosal layer and does not demonstrate lymph node metastasis is recommended. Tumors ≥2 cm, with lymph node metastasis, are indicated for surgical treatment. The treatment strategy for tumors between 10 and 20 mm in size remains controversial. [2] We present a rare case of a 60-year-old male patient with end-stage renal failure who underwent a screening pretransplantation endoscopic control. Colonoscopy had no pathological findings. Gastroscopy reveals an abnormal mucosa in the anterior upper part of the duodenal bulb that was described as a micronodular mucosa and a central nodule of 6 mm with erythematous mucosa. Histology of the micronodular mucosa reveals a heterotopic gastric mucosa and a small hyperplastic polyp. Biopsies from the nodule reveal a carcinoid tumor (NET GI. Immunohistochemistry: Positive chromogranin levels, low mitotic index (1/10 HPF, and Ki-67 index 2 cm and those of the duodenal bulb with histological extensions and the lack of assessing depth invasion.

    The objective of this work was to report success rates as well as potential obstacles in transnasal endoscopic resection of anterior skull base meningiomas. The study design was a case series with chart review at tertiary referral centers in South Australia and New Zealand. The patients were 37 consecutive patients who underwent endoscopic resection of skull-base meningiomas between 2004 and 2013. Review of patient charts and operative details were performed. Outcomes including complications are reported. Eighty-four percent of patients were women. There were 28 primary and 9 revision cases. Tumor locations were as follows: 14 olfactory groove/subfrontal; 12 planum/jugum sphenoidale; 7 tuberculum sellae; 3 clinoidal; and 1 clival. Vision change was the most common presenting symptom. Mean tumor volume was 33.68 cm(3) , mean diameter was 2.78 cm. Average operating times decreased with an initial learning curve and then plateaued. Primary tumors larger than 60 cm(3) took an average of 10 hours to resect. Gross total removal was achieved in 29 patients. There were no perioperative deaths. Two deaths occurred within 1 year of surgery. Postoperative cerebrospinal fluid (CSF) leaks occurred in 13 patients. Seventy-five percent of patients presenting with visual loss reported visual improvement. Of the 29 patients considered to have had complete resection at surgery, one was found to have residual disease on a postoperative magnetic resonance imaging (MRI) and another one later developed radiological evidence of recurrence. Using a 2-team approach, meningiomas of the skull base were successfully removed via an intranasal endoscopic technique. Although complete resection is typically possible even with large tumors, the lengthy resection required time for tumors larger than 60 cm(3) (diameter ≥4 cm) may obviate some of the advantages of this approach. The rate of postoperative CSF leak decreases when a synthetic dural substitute is added but does not approach zero.

    Per-oral endoscopic myotomy (POEM) has emerged as an endoscopic treatment of achalasia. There are no pre-procedural imaging modalities to predict the safest and the most efficacious approach. To evaluate the use of optimal coherence tomography (OCT) in providing a pre-procedural esophageal assessment. Patients undergoing POEM from July 2013 to November 2015 were captured in a multicenter, international registry. Patients who underwent OCT pre-POEM ("OCT arm") were compared to patients without pre-POEM OCT ("control arm"). OCT images were assessed for the degree of vascularity and the thickness of the circular muscular layer, and an approach was determined. A total of 84 patients were captured in the registry. Fifty-one patients underwent pre-POEM OCT. Using OCT as a guide, 24 (47 %) of patients underwent anterior POEM while 27 (53 %) underwent posterior POEM. Technical success was achieved in 96 % of patients. Significantly less bleeding occurred in the OCT arm when compared to the control group [4 (8 %) vs. 14 (43 %), p = 0.0001]. As a result, procedural time was significantly lower in the OCT group as compared to the control group (85.8 vs. 121.7 min, p = 0.000097). Pre-POEM OCT results in a reduction in procedural bleeding which contributes to a reduction in overall procedural time. NCT01438385.

    Endonasal endoscopic dacryocystorhinostomy (EN-DCR) is now a well-established procedure to relieve nasolacrimal duct obstruction, becoming its domain for the ENT surgeons indispensable. The aim of the present study is to report the experience of the Otorhinolaryngology Department of the University of São Paulo Medical School in the management of the obstruction of the drainage of the nasolacrimal system by EN-DCR, comparing with the results in literature. clinical retrospective. We reviewed the medical records of 17 patients (17 eyes) that were submitted to EN-DCR between april 2001 and july 2004. We analysed: sex, age at the time of diagnosis, etiology, clinical findings, surgical technique, use of silicone tubes, follow-up and complications. Eight men and nine women, the age range was from 29 to 79 years (mean 42.6413.1 years), mean follow-up time: 15 months, presented a lacrimal clinic with epiphora. Powered DCR was performed in 06 cases and YAG LASER in 01 patient. Silicone tubes were used in all cases and left in place mean 7.9 weeks. The surgical success rate was 82,3%. EN-DCR showed one safe technique, with advantages in relation to the external technique. So ophthalmologists and ENT physicians must work in harmony to offer more benefits to its patients.

    Percutaneous endoscopic gastrostomy feeding provides enteral nutrition to patients with neurological dysphagia. Thirty-day mortality rates of 4-26% have been reported, with pneumonia being the common cause post-percutaneous endoscopic gastrostomy insertion. This retrospective analysis of percutaneous endoscopic gastrostomy tube insertions in Malta (January 2008 - June 2010) compares the incidence of pneumonia in patients fed through a nasogastric tube versus in those fed via a percutaneous endoscopic gastrostomy tube. We analyzed the indications, poor prognostic factors and mortality for percutaneous endoscopic gastrostomy insertion. Ninety-seven patients underwent percutaneous endoscopic gastrostomy insertion. Fifty-four patients received nasogastric feeds before percutaneous endoscopic gastrostomy feeds. Patients on nasogastric feeds developed 32 episodes of pneumonia over a total of 7884 days of feeds (1 every 246 days). Patients with percutaneous endoscopic gastrostomy feeds after a period of nasogastric feeds developed 48 pneumonia episodes over 36,238 days (1 every 755 days). Patients with percutaneous endoscopic gastrostomy feeds without previous nasogastric feeds developed 28 pneumonia episodes over 23,983 days (1 every 856 days), and this was statistically significant (χ 2 test p value nasogastric feeds. However, pneumonia is still the major cause of death among percutaneous endoscopic gastrostomy patients.

    Robotic-assisted techniques are continuing to cement their role in coronary surgery, particularly in facilitating the endoscopic harvesting of the left internal mammary artery (LIMA), regardless of how the subsequent bypass grafting is performed. As more surgeons attempt to become trained in robotic-assisted procedures, we sought to better define the learning curve associated with robotic-assisted endoscopic LIMA harvest. Between January 2011 and July 2012, a total of 77 patients underwent robotic-assisted minimally invasive direct coronary artery bypass surgery at our institution. The LIMA was harvested endoscopically in all patients, using standard robotic instruments, followed by direct grafting to anterior wall myocardial vessels via a small thoracotomy. Intraoperative times for various components of the procedure were collated and analyzed. The mean ± SD time taken to insert and position the ports for the robotic instruments was 3.9 ± 1.4 minutes. The mean ± SD LIMA harvest time was 31.8 ± 10.1 minutes, and the mean ± SD total robotic time was 44.2 ± 12.9 minutes. All time variables consistently continued to decrease as the experience of the operating surgeon increased, with the greatest magnitude of improvement being evident within the first 20 cases. The logarithmic learning curves for LIMA harvest time and total robot time during our entire experience were both calculated as 90%, correlating to an expected 10% improvement in performance for each doubling of cases completed. Coronary surgeons can rapidly become proficient in robotic-assisted endoscopic LIMA harvest, with significant improvement in operative times evident within the first 20 cases completed. These data may be useful in designing appropriate training programs for newer surgeons seeking to gain experience in robotic-assisted coronary surgery.

    2004-10-01

    Fibrous dysplasia, a rare bony disease, is characterised by substitution of normal bone with immature tissue embedded in a fibrous stroma. It can be either monostotic or involve several bones. Fibrous dysplasia is usually asymptomatic but, in the advanced stage, pain due to neural compression or pathological fractures may occur. In the case of cranio-facial involvement, ocular, masticatory, respiratory or auditory functional alterations are possible. A case of fibrous dysplasia, limited to the middle turbinate and associated with Widal triad (sinus-nasal polyposis, asthma, acetyl salicylic acid intolerance), is described. Craniofacial computed tomography revealed enlargement of left middle turbinate with characteristic "ground-glass" appearance. The patient underwent anterior bilateral functional endoscopic sinus surgery with near-total resection of left middle turbinate. Histopathological examination confirmed the diagnosis of fibrous dysplasia. After 2 years the patient is still asymptomatic. Videorhinoscopy shows good sinus-nasal patency without disease recurrence. Even though exceptional, localization of fibrous dysplasia at middle turbinate has been described, therefore, it must be considered in the differential diagnosis of the craniofacial ossifying disorder. For localized and symptomatic lesions, endoscopic surgery is an effective option. Scrupulous life-long follow-up is necessary due to the high percentage of recurrence and possible malignant degeneration.

    Per-Oral Endoscopic Myotomy (POEM) is becoming an acceptable alternative to laparoscopic cardiomyotomy for esophageal motility disorders. The aim of this video is to provide key technical steps to completing this procedure. Each patient underwent diagnostic investigations including high resolution manometry (HRM), esophageogastroduodenoscopy (EGD), and timed-barium swallow for primary esophageal motility disorders preoperatively. Patients undergoing POEM procedures are preoperatively prepared by taking Nystatin swish-and-swallow for 3 days, 24 h of clear liquid diet, and 12 h of NPO. Preoperative antibiotics are given. Under general anesthesia and with the patient in the supine position, endoscopy with CO2 insufflation is prepared. Special endoscopic instruments and electrocautery settings are required to perform the POEM procedure, as illustrated in the slides. POEM is performed in six key/critical steps: (1) diagnostic endoscopy; (2) taking measurements; (3) esophageal mucosotomy creation; (4) submucosal tunneling; (5) selective circular myotomy of the anterior lower esophageal sphincter; and (6) closure of the mucosotomy. According to our protocol, all patients get an esophogram the next morning after surgery prior to discharge. The patient receives objective testing (HRM with 24 PH Impedance test, EGD, and timed-barium swallow) 6 months postoperatively. In six key steps, POEM can be accomplished as described in the video.

    Endoscopic sleeve gastroplasty (ESG) is gaining traction as a minimally invasive bariatric treatment. Concern that the learning curve may be slow, even among those proficient in endoscopic suturing, is a barrier to widespread implementation of the procedure. Therefore, we aimed to define the learning curve for ESG in a single endoscopist experienced in endoscopic suturing who participated in a 1-day ESG training program.  Consecutive patients who underwent ESG between February 2016 and November 2016 were included. The performing endoscopist, who is proficient in endoscopic suturing for non-ESG procedures, participated in a 1-day ESG training session before offering ESG to patients. The outcome measurements were length of procedure (LOP) and number of plications per procedure. Nonlinear regression was used to determine the learning plateau and calculate the learning rate.  Twenty-one consecutive patients (8 males), with mean age 47.7 ± 11.2 years and mean body mass index 41.8 ± 8.5 kg/m 2 underwent ESG. LOP decreased significantly across consecutive procedures, with a learning plateau at 101.5 minutes and a learning rate of 7 cases ( P  = 0.04). The number of plications per procedure also decreased significantly across consecutive procedures, with a plateau at 8 sutures and a learning rate of 9 cases ( P  < 0.001). Further, the average time per plication decreased significantly with consecutive procedures, reaching a plateau at 9 procedures ( P  < 0.001).  Endoscopists experienced in endoscopic suturing are expected to achieve a reduction in LOP and number of plications per procedure in successive cases, with progress plateauing at 7 and 9 cases, respectively.

    Capsule endoscopy performed via the traditional peroral route is technically challenging in patients with dysphagia, gastroparesis, and/or abnormal upper-GI (UGI) anatomy. To describe the indications and outcomes of cases in which the AdvanCE capsule endoscope delivery device, which has recently been cleared by the Food and Drug Administration, was used. Retrospective, descriptive, case series. Tertiary care, university hospital. We report a case series of 16 consecutive patients in whom the AdvanCE delivery device was used. The study period was May 2005 through July 2006. Endoscopic delivery of the video capsule to the proximal small bowel by using the AdvanCE delivery device. Indications, technique, and completeness of small bowel imaging in patients who underwent endoscopic video capsule delivery. The AdvanCE delivery device was used in 16 patients ranging in age from 3 to 74 years. The primary indications for endoscopic delivery included inability to swallow the capsule (10), altered UGI anatomy (4), and gastroparesis (2). Of the 4 patients with altered UGI anatomy, 3 had dual intestinal loop anatomy (ie, Bilroth-II procedure, Whipple surgery, Roux-en-Y gastric bypass) and 1 had a failed Nissen fundoplication. In all cases, the capsule was easily deployed without complication, and complete small intestinal imaging was achieved. Small patient size. Endoscopic placement of the Given PillCam by use of the AdvanCE delivery device was safe and easily performed in patients for whom capsule endoscopy would otherwise have been contraindicated or technically challenging.

    Full Text Available O carcinoma epidermóide da laringe é a sexta neoplasia mais comum, sendo uma das neoplasias malignas mais freqüentes na cabeça e pescoço, ocupando o segundo lugar imediatamente após o câncer da cavidade oral. FORMA DE ESTUDO: Estudo clínico retrospectivo. MATERIAL E MÉTODO: Entre os anos de 1991 e 2003, 24 pacientes portadores de lesões glóticas envolvendo a comissura anterior foram submetidos a laringectomia frontal anterior com epiglotoplastia descrita por Tucker e colaboradores no ano de 1979. RESULTADO: Nossos resultados confirmam aqueles encontrados em outras publicações. Não ocorreram mortes no pós-operatório e o seguimento foi relativamente simples. Todos os pacientes foram decanulizados e recuperaram um efetivo trato digestivo e aéreo. CONCLUSÃO: Nossos achados mostram que a laringectomia pela técnica de Tucker é uma cirurgia efetiva para o tratamento dos carcinomas glóticos que acometem a comissura anterior e a porção membranosa das cordas vocais com a motilidade preservada, pois tais lesões não devem ser tratadas pela ressecção endoscópica trans-oral ou por uma laringectomia fronto lateral.Squamous cell carcinoma of the larynx is the sixth most common neoplasia, being the second neoplasia of the head and neck, after oral cancer. STUDY DESIGN: Retrospective clinical study chart review. MATERIAL AND METHOD: From 1991 to 2003, 24 patients whose glottic lesions involving anterior comissure were operated with a reconstructive anterior frontal laryngectomy with epiglotoplasty, such as described by Tucker et al in 1979. RESULTS: Our functional results confirm those reported in the previous publications. There were no post-operative mortalities and follow-up was usually uncomplicated. All patients underwent decanulation and were able to eat by tract normal. CONCLUSION: Our findings show that partial laryngectomy by Tucker's technique is an effective surgical approach for glottic carcinoma at the anterior comissure

    We sought to evaluate the feasibility, safety, and difficulty of performing the per-oral endoscopic myotomy (POEM) procedure in the setting of a prior Heller myotomy using a survival porcine model. Four pigs underwent laparoscopic Heller myotomy with Dor partial anterior fundoplication followed by the POEM performed 4 weeks later. Two additional pigs served as controls, undergoing only the POEM. All procedures were completed without complications. The revisional POEM was not significantly more difficult than POEM controls based on procedure time, POEM procedure components, or procedure difficulty scores. Revisional POEM had a longer mean operative time when compared with Heller myotomy (126.0 vs. 83.8 min; Pmyotomy is safe and feasible in the porcine model and has potential as an option for patients suffering from recurrent or persistent symptoms after failed surgical myotomy.

    Posterior urethral injury requires meticulous tertiary care and optimum expertise to manage successfully. The aim of our study is to describe our experiences with pelvic injuries involving posterior urethra and their outcome after early endoscopic realignment. A prospective study was carried out in 20 patients with complete posterior urethral rupture, from November 2007 till October 2010. They presented with blunt traumatic pelvic fracture and underwent primary realignment of posterior urethra in our institute. The definitive diagnosis of urethral rupture was made after retrograde urethrography and antegrade urethrography where applicable. The initial management was suprapubic catheter insertion after primary trauma management in casualty. After a week of conservative management with intravenous antibiotics and pain management, patients were subjected to the endoscopic realignment. The follow up period was at least six months. The results were analyzed with SPSS software. After endoscopic realignment, all patients were advised CISC for the initial 3 months. All patients voided well after three months of CISC. However, 12 patients were lost to follow up by the end of 6 postoperative months. Out of eight remaining patients, two had features of restricture and were managed with DVU followed by CISC again. One patient with restricture had some degree of erectile dysfunction who improved significantly after phospodiesterase inhibitors. None of the patients had features of incontinence. Early endoscopic realignment of posterior urethra is a minimally invasive modality in the management of complete posterior urethral injury with low rates of incontinence and impotency.

    Full Text Available Traumatic bile leaks often result in high morbidity and prolonged hospital stay that requires multimodality management. Data on endoscopic management of traumatic bile leaks are scarce. Our study objective was to evaluate the efficacy of the endoscopic management of a traumatic bile leak. We performed a retrospective case review of patients who were referred for endoscopic retrograde cholangiopancreatography (ERCP after traumatic bile duct injury secondary to blunt (motor vehicle accident or penetrating (gunshot trauma for management of bile leaks at our tertiary academic referral center. Fourteen patients underwent ERCP for the management of a traumatic bile leak over a 5-year period. The etiology included blunt trauma from motor vehicle accident in 8 patients, motorcycle accident in 3 patients and penetrating injury from a gunshot wound in 3 patients. Liver injuries were grade III in 1 patient, grade IV in 10 patients, and grade V in 3 patients. All patients were treated by biliary stent placement, and the outcome was successful in 14 of 14 cases (100%. The mean duration of follow-up was 85.6 days (range 54-175 days. There were no ERCP-related complications. In our case review, endoscopic management with endobiliary stent placement was found to be successful and resulted in resolution of the bile leak in all 14 patients. Based on our study results, ERCP should be considered as first-line therapy in the management of traumatic bile leaks.

    To investigate the outcomes of overlay myringoplasty by comparing the endoscopic versus the microscopic approach. This is a retrospective comparative study of 181 patients who underwent myringoplasty with overlay techniques between January 2010 and 2016 at Songklanagarind Hospital, Thailand. Group 1 underwent an endoscopic-assisted (n=90), and group 2 underwent the microscopic-assisted (n=91) overlay myringoplasty. The outcomes were graft take rates, the audiometric results, the need of canalplasty, complications and operative time. All patients were followed up for at least 6months. The graft take rates were 96.7% in the endoscopic group and 91.2% in the microscopic group, p=0.22. The operative time was 98.9±11.0min for the endoscopic group, and 176.6±14.9min for the microscope group, poverlay myringoplasty provided satisfactory surgical as well as audiometric outcomes when compared with the microscopic approach. The graft take rate and postoperative hearing were similar in both groups. The endoscopic approach seemed to be superior than the microscopic approach in term of operative time, complication, and no need for canalplasty. Copyright © 2017 Elsevier Inc. All rights reserved.

    Transanal endoscopic microsurgery is considered a safe, appropriate, and minimally invasive approach, and complications after endoscopic microsurgery are rare. We report a case of sepsis and pneumoretroperitoneum after resection of a rectal lateral spreading tumor. The patient presented with rectal mucous discharge. Colonoscopy revealed a rectal lateral spreading tumor. The patient underwent an endoscopic transanal resection of the lesion. He presented with sepsis of the abdominal focus, and imaging tests revealed pneumoretroperitoneum. A new surgical intervention was performed with a loop colostomy. Despite the existence of other reports on pneumoretroperitoneum after transanal endoscopic microsurgery, what draws attention to this case is the association with sepsis.

    Osgood-Schlatter disease is a common cause of anterior knee pain in sports-practicing adolescents. The long-term outcomes have not always been favorable, and some adolescents have persisting knee pain into adulthood. Excision of the ossicle together with debridement of the tibial tuberosity is indicated if the pain is not relieved with conservative measures. An endoscopic technique for excision of the ossicle associated with Osgood-Schlatter disease is reported. It has the advantages of avoidance of painful surgical scars and preservation of the integrity of the patellar tendon, with the potential for improved cosmetic and functional results.

    We clinically investigated 34 patients with obstructive colorectal cancer who underwent placement of a colonic stent as a bridge to surgery(BTS), focusing on endoscopic findings after stent placement.Twenty -nine patients(85.3%)underwent colonoscopy after stent placement, and the entire large intestine could be observed in 28(96.6%).Coexisting lesions were observed in 22(78.6%)of these 28 patients.The lesions comprised adenomatous polyps in 17 patients(60.7%), synchronous colon cancers in 5 patients(17.9%), and obstructive colitis in 3 patients(10.7%), with some overlapping cases.All patients with multiple cancers underwent one-stage surgery, and all lesions were excised at the same time.Colonoscopy after colonic stent placement is important for preoperative diagnosis of coexisting lesions and planning the extent of resection. These considerations support the utility of colonic stenting for BTS.

    The authors' initial experience with the endoscopic extradural supraorbital approach to the temporal pole and adjacent area is reported. Fully endoscopic surgery using the extradural space via a supraorbital keyhole was performed for tumors in or around the temporal pole, including temporal pole cavernous angioma, sphenoid ridge meningioma, and cavernous sinus pituitary adenoma, mainly using 4-mm, 0° and 30° endoscopes and single-shaft instruments. After making a supraorbital keyhole, a 4-mm, 30° endoscope was advanced into the extradural space of the anterior cranial fossa during lifting of the dura mater. Following identification of the sphenoid ridge, orbital roof, and anterior clinoid process, the bone lateral to the orbital roof was drilled off until the dura mater of the anterior aspect of the temporal lobe was exposed. The dura mater of the temporal lobe was incised and opened, exposing the temporal pole under a 4-mm, 0° endoscope. Tumors in or around the temporal pole were safely removed under a superb view through the extradural corridor. The endoscopic extradural supraorbital approach was technically feasible and safe. The anterior trajectory to the temporal pole using the extradural space under endoscopy provided excellent visibility, allowing minimally invasive surgery. Further surgical experience and development of specialized instruments would promote this approach as an alternative surgical option.

    2016-01-01

    This case report is intended to inform clinicians, endoscopists, policy makers and industry of our experience in the management of a rare case of mobile phone ingestion. A 29-year-old prisoner presented to the Emergency Department with vomiting, ten hours after he claimed to have swallowed a mobile phone. Clinical examination was unremarkable. Both initial and repeat abdominal radiographs eight hours later confirmed that the foreign body remained in situ in the stomach and had not progressed along the gastrointestinal tract. Based on these findings, upper endoscopy was performed under general anaesthesia. The object could not be aligned correctly to accommodate endoscopic removal using current retrieval devices. Following unsuccessful endoscopy, an upper midline laparotomy was performed and the phone was delivered through an anterior gastrotomy, away from the pylorus. The patient made an uneventful recovery and underwent psychological counselling prior to discharge. In this case report, the use of endoscopy in the management when a conservative approach fails is questioned. Can the current endoscopic retrieval devices be improved to limit the need for surgical interventions in future cases? An ingested mobile phone in the stomach may not be amenable for removal using the current endoscopic retrieval devices. Improvements in overtubes or additional modifications of existing retrieval devices to ensure adequate alignment for removal without injuring the oesophagus are needed. Copyright © 2016 The Authors.

    Endoscopic incision of ureterocele is considered a simple and safe method for decompression of urinary tract obstruction above ureterocele. The purpose of this study was to evaluate the radiological findings after endoscopic incision of ureterocele. We retrospectively reviewed the radiological findings (ultrasonography (US), intravenous urography, and voiding cystourethrography(VCU)) in 16 patients with ureterocele who underwent endoscopic incision (mean age at surgery, 15 months; M:F 3:13; 18 ureteroceles). According to the postoperative results, treatment was classified as successful when medical treatment was still required, and second operation when additional surgical treatment was required. Postoperative US (n=10) showed that in all patients, urinary tract obstruction was relieved: the kidney parenchima was thicker and the ureterocele was smaller. Intravenous urography (n=8), demonstrated that in all patients, urinary tract obstruction and the excretory function of the kidney had improved. Postoperative VCU indicated that in 92% of patients (12 of 13), endoscopic incision of the ureterocele led to vesicoureteral reflux(VUR). Of these twelve, seven (58%) showed VUR of more than grade 3, while newly developed VUR was seen in five of eight patients (63%) who had preoperative VCU. Surgery was successful in four patients (25%), partially successful in three (19%), and a second operation-on account of recurrent urinary tract infection and VUR of more than grase 3 during the follow-up period-was required by nine (56%). Although endoscopic incision of a ureterocele is a useful way of relieving urinary tract obstruction, an ensuing complication may be VUR. Postoperative US and intravenous urography should be used to evaluate parenchymal change in the kidney and improvement of uronary tract obstructon, while to assess the extend of VUR during the follow-up period , postoperative VCU is required

  17. Endoscopic Pubic Symphysectomy for Athletic Osteitis Pubis.

    Matsuda, Dean K; Sehgal, Bantoo; Matsuda, Nicole A

    2015-06-01

    Osteitis pubis is a common form of athletic pubalgia associated with femoroacetabular impingement. Endoscopic pubic symphysectomy was developed as a less invasive option than open surgical curettage for recalcitrant osteitis pubis. This technical note demonstrates the use of the anterior and suprapubic portals in the supine lithotomy position for endoscopic burr resection of pubic symphyseal fibrocartilage and hyaline endplates. Key steps include use of the suprapubic portal for burr resection of the posteroinferior symphysis and preservation of the posterior and arcuate ligaments. Endoscopic pubic symphysectomy is a minimally invasive bone-conserving surgery that retains stability and may be useful in the treatment of recalcitrant osteitis pubis or osteoarthritis. It nicely complements arthroscopic surgery for femoroacetabular impingement and may find broader application in this group of co-affected athletes.

    Background and study aims  Double endoscopic bypass entails EUS-guided gastroenterostomy (EUS-GE) and EUS-guided biliary drainage (EUS-BD) in patients who present with gastric outlet and biliary obstruction. We report a multicenter experience with double endoscopic bypass. Patients and methods  Retrospective, multicenter series involving 3 US centers. Patients who underwent double endoscopic bypass for malignant gastric and biliary obstruction from 1/2015 to 12/2016 were included. Primary outcome was clinical success defined as tolerance of oral intake and resolution of cholestasis. Secondary outcomes included technical success, re-interventions and adverse events (AE). Results  Seven patients with pancreatic head cancer (57.1 % females; mean age 64.6 ± 12.5 years) underwent double endoscopic bypass. Four patients had EUS-GE and EUS-BD performed during the same session with a mean procedure time of 70 ± 20.4 minutes. EUS-GE and EUS-BD were technically successful in all patients, all of whom were able to tolerate oral intake with resolution of cholestasis in 6 (87.5 %). One patient had a repeat EUS-BD with normalization of bilirubin. There were no adverse events. Conclusions  Double endoscopic bypass is feasible and effective when performed by experienced operators. Studies comparing this novel concept to existing techniques are warranted. PMID:28924596

    Aim: To describe the radiological, endoscopic, and pathological findings of gastric schwannomas in 16 patients. Materials and methods: The radiological, endoscopic, and pathological findings of 16 surgically proven cases of gastric schwannoma were retrospectively reviewed. All patients underwent computed tomography (CT) and four patients were evaluated with upper gastrointestinal series. Two radiologists reviewed the CT and upper gastrointestinal series images by consensus with regard to tumour size, contour, margin, and growth pattern, the presence or absence of ulcer, cystic change, and the CT enhancement pattern. Endoscopy was performed in eight of these 16 patients. Six patients underwent endoscopic ultrasonography. Pathological specimens were obtained from and reviewed in all 16 patients. Immunohistochemistry was performed for c-kit, CD34, smooth muscle actin, and S-100 protein. Results: On radiographic examination, gastric schwannomas appeared as submucosal tumours with the CT features of well-demarcated, homogeneous, and uncommonly ulcerated masses. Endoscopy with endoscopic ultrasonography demonstrated homogeneous, submucosal masses contiguous with the muscularis propria in all six examined cases. On pathological examination, gastric schwannomas appeared as well-circumscribed and homogeneous tumours in the muscularis propria and consisted microscopically of interlacing bundles of spindle cells. Strong positivity for S-100 protein was demonstrated in all 16 cases on immunohistochemistry. Conclusion: Gastric schwannomas appear as submucosal tumours of the stomach and have well-demarcated and homogeneous features on CT, endoscopic ultrasonography, and gross pathology. Immunohistochemistry consistently reveals positivity for S-100 protein in the tumours.

    Full Text Available Background: The use of endoscope for the management of pituitary adenoma is not new. The better magnification and illumination provided by the endoscope gives better outcome than microscopic pituitary surgery. Objective: To find out the benefits of endoscope in relation to microscopic surgery. Materials and Methods: We performed 45 cases of pituitary adenoma surgery by endoscopic endonasal approach from July 2008 to July 2010. Results: Forty five cases underwent endoscopic transsphenoidal approach. Gross total removal was done in 35 cases and subtotal removal was done in 10 cases. Residual tumours were seen in 10 cases (22% in postoperative follow-up MRI scan. Visual improvement was satisfactory, and hormonal improvement of functional adenoma was nice. Postoperative visual acuity and visual field were improved in 75% cases. There were 37% cases of temporary diabetes insipidus and about 4.5% cases of permanent diabetes insipidus. The average duration of follow-up was 20 months. One patient required reexploration to correct visual deterioration in the immediate postoperative period. There were 4.5% cases of CSF leak and 6.6% mortality. Mortality was due to electrolyte imbalance and improper management of infection and hydrocephalus. Conclusion: Endoscopic endonasal pituitary surgery now has become a gold standard surgery for most of the pituitary adenomas because of its better advantages in relation to microscopic surgery and less complications and less hospital stay.

    2002-06-01

    The epigastric pain is the most frequent manifestation in chronic pancreatitis. It is due to intraductal pancreatic pressure, presence of compressive pseudocysts and probably to neuroinflammatory process caused by alcohol. The aim of our study was to assess the influence of endoscopic treatment on pain in chronic pancreatitis and the correlation between residual pain after endoscopic treatment and pancreatic morphology. Forty-four patients from the Gastroenterology Department of Angers (France) with chronic pancreatitis were included in our retrospective clinical study. Thirty-seven patients underwent a diagnostic ERCP and only 28 needed an endoscopic treatment. The pain was evaluated semi-quantitatively before and after the endoscopic treatment. The mean follow-up was 28.6 months. Among the 28 patients with endoscopic treatment, 18 had a complete improvement of the pain, 4 an incomplete improvement and 6 had no improvement; these last were submitted to pancreatic surgery. The pain evolution had a good correlation with the reduction of Wirsung diameter; there was no correlation with ductal stenosis, residual lithiasis and pseudocysts presence. Alcohol consumption had no influence on the pain evolution. The endoscopic treatment of intraductal lithiasis and pseudocysts is a useful method for Wirsung decompression, improving the pain in chronic pancreatitis.

    Full Text Available Spontaneous sphenoid sinus lateral wall meningoceles are rare lesions with an unknown etiology. Endoscopic endonasal technique is a considerable route in the treatment of this condition. The aim of this paper is to report the etiology, surgical technique, and outcome in a patient repaired via endoscopic endonasal approach. A 51-year-old male patient applied with rhinorrhea started three months ago after an upper respiratory infection. There were no history of trauma or sinus operation. Biochemical analysis of the fluid was positive for beta-2-transferrin. This asypthomatic patient had undergone for repairment of lateral sphenoid sinus meningocele with endoscopic endonasal transsphenoidal approach. After endoscopic endonasal meningocele closure procedure no complications occured and a quick recovery was observed. Endoscopic endonasal approach is an effective and safe treatment modality of spontaneous lateral sphenoid sinus meningoceles and efficient in anterior skull base reconstruction.

    A 20 mm hole made backwards from the midpoint of the asterion to the mastoid process is suitable for a retrosigmoid keyhole approach with the aid of an endoscope. The endoscope-assisted retrosigmoid keyhole approach can be considered an effective and safe method for removal of vestibular schwannoma. To investigate the feasibility of the endoscope-assisted retrosigmoid keyhole approach for exposing the cerebellopontine angle (CPA) and internal auditory canal (IAC). With the aid of an endoscope, we simulated surgical procedures in 30 sides of 15 formalin-fixed cadaver heads. (1) For 24 (80%) sides, the midpoint of the top notch to the mastoid process was in the anterior edge of the sigmoid sinus; for 27 sides (90%) the midpoint of the asterion to the mastoid process was in the posterior edge of the sigmoid sinus. (2) The IAC and CPA were exposed by the retrosigmoid keyhole approach with the aid of the endoscope.

    Colorectal adenomas are well known precursors of invasive adenocarcinoma. Colonoscopy is the gold standard for adenoma detection. Colonoscopy is far more than a diagnostic tool, as it allows effective treatment of colorectal adenomas. Endoscopic resection of colorectal adenomas has been shown to reduce the incidence and mortality of colorectal cancer. Difficult resection techniques are available, such as endoscopic mucosal resection, endoscopic submucosal dissection and endoscopic full-thickness resection. This review aims to provide an overview of the different endoscopic resection techniques and their indications, and summarizes the current recommendations in the recently published guideline of the European Society of Gastrointestinal Endoscopy.

    Wireless capsule endoscopy (WCE) is an increasingly used procedure for visualization of the small intestine. One challenge in pediatric WCE is the placement of the capsule in a population unable to swallow it for a variety of reasons. Here we present a novel use of the real-time (RT) viewer in the endoscopic deployment of the capsule endoscope. We performed a retrospective chart review on all WCE completed at the Children's Memorial Hospital from February 2010 to May 2011. Following a diagnostic upper endoscopy, the RT viewer was attached to the capsule recorder and image was noted before insertion. The endoscope and AdvanCE capsule delivery device were slowly advanced into duodenum while maintaining visualization on the RT viewer. A total of 17 patients who underwent a WCE with endoscopic placement were identified. They ranged in ages from 2 to 19 years. Thirteen patients required endoscopic placement because of the inability to swallow the capsule, whereas 4 were placed during a scheduled procedure to take advantage of sedation and airway protection. All of the 17 patients had successful deployment of the capsule into the duodenal lumen. In each case, the endoscopist was able to confirm capsule location in duodenum during scope withdrawal. There was no evidence of iatrogenic trauma or bleeding in any patient. There were 5 incomplete studies, a completion rate consistent with that described in the literature. The use of the RT viewer for endoscopic deployment of WCE is an effective technique to improve visualization of capsule placement in the pediatric population.

  9. Sedation Monitoring and Management during Percutaneous Endoscopic Lumbar Discectomy

    Full Text Available Percutaneous endoscopic laser discectomy (PELD is a painful intervention that requires deep sedation and analgesia. However, sedation should be light at some point because cooperation by the patient during the procedure is required for successful surgical treatment. Light sedation poses a problem for endotracheal intubation, while patients placed in the prone position during percutaneous endoscopic discectomy pose a problem for airway management. Therefore, under these conditions, sedation should be not deeper than required. Here we report the sedation management of three cases that underwent PELD, with a focus on deep and safe sedation that was monitored using bispectral index score and observer’s assessment of alertness/sedation score.

    2009-01-01

    A multicenter study (BREATHE I - Entellus Medical, Inc.) was performed to assess the safety and outcomes of a new, less invasive system that uses direct endoscopic visualization to facilitate balloon dilation of the maxillary sinus ostia and ethmoid infundibulum. General anesthesia was avoided in most subjects to assess feasibility of performing transantral ostial dilatation in an office setting. Subjects with chronic rhinosinusitis of the maxillary sinuses alone or maxillary and anterior ethmoid sinuses underwent baseline evaluation including CT imaging and symptom assessment using the Sino-Nasal Outcome Test (SNOT 20). Subjects underwent transantral balloon dilation and follow-up evaluation at 1 week, 3 months, and 6 months post-procedure. Thirty subjects were treated at three centers. Fifty-five of 58 maxillary ostia were successfully treated for a procedural completion rate of 94.8%. Ninety-seven percent of the procedures were completed under local anesthesia with or without minimal intravenous sedation. There were no device-related serious adverse events or unanticipated adverse device effects. The mean overall SNOT 20 score at baseline was 2.9 +/- 1.0. Mean overall SNOT 20 scores at 1-week, 3-month, and 6-month follow-up were 0.8 +/- 0.8, 0.7 +/- 0.8, and 0.8 +/- 0.9 respectively. Patency at 3-months as confirmed by CT imaging was 95.8%. These results indicate that transantral balloon dilation of the ostiomeatal complex under local anesthesia appears to be a safe technique for managing isolated maxillary or maxillary and anterior ethmoid sinusitis and can potentially be performed safely in an office setting.

    2007-02-01

    Endoscopic laryngeal web formation has been used to elevate the speaking voice, primarily in male to female transsexuals as part of gender reassignment intervention. The goal of this article is to review the literature regarding surgical treatment for pitch elevation and to describe a novel method of laryngeal web formation. The results of this technique are also reported in a series of six patients. All patients were assessed and treated at the St. Michael's Hospital Voice Disorders Clinic, a tertiary referral centre for voice disorders. Pre- and postoperative voice recordings, acoustic analysis, and videostroboscopic examinations were performed in this series. The acoustic data collected included isolated vowel samples, a reading task, and a modified voice range profile. The patients all underwent successful endoscopic web formation with a Gelfoam augmentation technique. The voice results collected at least 6 months after vocal fold web formation demonstrate a dramatic increase in the habitual speaking fundamental frequency. This new modification for endoscopic web formation has been shown to be a successful procedure for permanent elevation of pitch with little or no morbidity.

    Endoscopic discectomy and fusions have been gaining popularity in the recent past and are noted to be safe for their application in elderly population. The procedure involves ultra-small incision for discectomy followed by placement of percutaneous screws in awake patients. Treatment of advanced spinal pathology with endoscope-assisted techniques is challenging. Although not common with the endoscopic approach, postoperative infection can be problematic, as there are no established guidelines on its management. A 76-year-old female patient underwent lumbar 4-5 endoscopic-assisted transforaminal lumbar interbody fusion for severe degenerative changes leading to back and radicular leg pain. She did well postoperatively and was discharged home the following day. She presented to the outside hospital with new onset of severe back pain, sepsis, and positive methicillin-susceptible Staphylococcus aureus with blood culture and demonstrated no improvement while on antibiotics. Initial magnetic resonance imaging revealed postoperative changes only. With positive blood culture and localized pain, she was then offered to undergo a percutaneous drainage of the abscess. Under local anesthesia and intravenous sedation, a small pocket of collection was found along the endoscopic trajectory from previous surgery. After evacuation of the collection, the interbody device was irrigated with vancomycin through endoscope. Postoperatively, immediate symptomatic improvement was noted in back pain. She was discharged home on oxacillin and continues to do well at 12 months' follow-up with excellent fusion. The present case illustrates the successful treatment of a surgical-site infection after endoscope-assisted transforaminal lumbar interbody fusion via a repeat percutaneous endoscopic approach.

    The ASGE Technology Committee provides reviews of existing, new, or emerging endoscopic technologies that have an impact on the practice of GI endoscopy. Evidence-based methodology is used, with a MEDLINE literature search to identify pertinent clinical studies on the topic and a MAUDE (U.S. Food and Drug Administration Center for Devices and Radiological Health) database search to identify the reported complications of a given technology. Both are supplemented by accessing the "related articles" feature of PubMed and by scrutinizing pertinent references cited by the identified studies. Controlled clinical trials are emphasized, but in many cases data from randomized, controlled trials are lacking. In such cases, large case series, preliminary clinical studies, and expert opinions are used. Technical data are gathered from traditional and Web-based publications, proprietary publications, and informal communications with pertinent vendors. Technology Status Evaluation Reports are drafted by 1 or 2 members of the ASGE Technology Committee, reviewed and edited by the committee as a whole, and approved by the Governing Board of the ASGE. When financial guidance is indicated, the most recent coding data and list prices at the time of publication are provided. For this review, the MEDLINE database was searched through February 2010 for articles related to automated endoscope reprocessors, using the words endoscope reprocessing, endoscope cleaning, automated endoscope reprocessors, and high-level disinfection. Technology Status Evaluation Reports are scientific reviews provided solely for educational and informational purposes.

    Minimally invasive surgery in skull base relying on searching for possible anatomic basis for endoscopic technology is controversial. The objective of this study was to observe the spatial relationships between main blood vessels and nerves in the cerebellopontine angle area and provide anatomic basis for lateral and posterior skull base minimally invasive surgery via endoscopic retrosigmoid keyhole approach. This study was conducted on thirty dried adult skulls to measure the spatial relationships among the surface bony marks of posterior cranial fossa, and to locate the most appropriate drilling area for retrosigmoid keyhole approach. In addition, we used 10 formaldehyde-fixed adult cadaver specimens for simulating endoscopic retrosigmoid approach to determine the visible scope. The midpoint between the mastoid tip and the asterion was the best drilling point for retrosigmoid approach. A hole centered on this point with the 2.0 cm in diameter was suitable for exposing the related structures in the cerebellopontine angle. Retrosigmoid keyhole approach can decrease the pressure on the cerebellum and expose the related structures effectively which include facial nerve, vestibulocochlear nerve, trigeminal nerve, glossopharyngeal nerve, vagus nerve, accessory nerve, hypoglossal nerve, anterior inferior cerebellar artery, posterior inferior cerebellar artery and labyrinthine artery, etc. Exact location on endoscope retrosigmoid approach can avoid dragging cerebellum during the minimally invasive surgery. The application of retrosigmoid keyhole approach will extend the application of endoscopic technology.

    The International Frontal Sinus Anatomy Classification (IFAC) was introduced to more accurately characterize ethmoid and frontal sinus pneumatization patterns. The prevalence of IFAC cells and their anatomic associations have not been described. The goal was to examine the prevalence of IFAC cells and determine radiologic features associated with a low-lying anterior ethmoidal artery (LAEA). Imaging of adult patients who underwent computed tomographies from January 2015 to March 2016 were retrospectively reviewed by using the IFAC classification. We also measured the distance from the skull base to the anterior ethmoidal artery (AEA), the height of the lateral lamella of the cribriform plate, and anterior-posterior diameter from the anterior wall of the frontal sinus to the skull base (APF). Patients with a history of sinus surgery, trauma, malignancy, or congenital anomaly were excluded. Statistical analysis was performed by using Pearson correlation coefficients and χ2 tests. A total of 95 patients met the inclusion criteria. There was a significant association between supraorbital ethmoid cells and an LAEA (p < 0.001), with a significant effect size (φ = 0.276, p = 0.007). An inverse relationship was observed between Keros type I classification I and an LAEA (p < 0.001), with a significant effect size (φ = -0.414, p = 0.000). Significant associations were found between the AEA distance from the skull base and the cribriform lateral lamella height (R = 0.576, p < 0.001). In addition, there was a significant association between the AEA distance from the skull base and the APF (R = 0.497, p < 0.001). The presence of a supraorbital ethmoid cell and a wide APF were associated with an LAEA. There was a significant relationship between Keros type I classification and the AEA adjacent to the skull base. Delineation of these anatomic relationships may be helpful during endoscopic sinus surgery to avoid complications.

    Full Text Available Positive airway pressure is the treatment of choice among obstructive sleep apnea syndrome patients. Among surgical options, multilevel approach is a good option in patients with an involvement of all tract of first airway. The aim of the present work is to establish the efficacy of anterior palatoplasty in the treatment of selected patients with mild obstructive sleep apnea syndrome or simple snoring, within a multilevel surgery. The group was composed of 16 mild obstructive sleep apnea syndrome adult patients collected from January 2015 to June 2016 at University of Palermo, Ear, Nose and Throat Department. To make diagnosis of obstructive sleep apnea syndrome, we employed polysomnography, the Epworth Sleepiness Scale and an endoscopic study of aerodigestive tract in order to identify the sites of collapse. All patients underwent to inferior turbinate reduction, anterior pharyngoplasty and hyoid suspension. After treatment, 11 patients had Apnea Hypopnea Index ≤5 and 4 patients less than 50% compared to the starting one. According to Epworth Sleepiness Scale, the daytime sleepiness enhanced from 12.6 to 8.6 post-operative average. Pre-operative mean value of Muller’s maneuver was N (nose:2.6, O (oropharinx: 3.4, H (hypopharinx:2.5 Before performing surgical procedure each patient was subjected to sleep endoscopy to evaluate better the pattern of collapse. The post-operative mean outcomes of Mueller’s Maneuver was: N 1.5, O 1.3, H 1.3. Barbed Anterior pharyngoplasty, combined with other surgical procedures, can be considered a valid surgical option to relieve snoring, and mild apnoic events. Our preliminary results, show that the anterior palatoplasty, combined with other surgical procedures, can be considered a valid surgical option to relieve snoring and mild apnoic events.

  18. Choledocholithiasis diagnostics – endoscopic ultrasound or endoscopic retrograde cholangiopancreatography?

    2014-06-01

    Full Text Available It is estimated that 3.4% of patients qualified for cholecystectomy due to cholelithiasis have a coexisting choledocholithiasis. For decades, endoscopic ascending retrograde cholangiopancreatography has been the golden diagnostic standard in cases of suspected choledocholithiasis. The method is associated with a relatively high rate of complications, including acute pancreatitis, the incidence of which is estimated to range between 0.74% and 1.86%. The mechanism of this ERCP-induced complication is not fully understood, although factors increasing the risk of acute pancreatitis, such as sphincter of Oddi dysfunction, previous acute pancreatitis, narrow bile ducts or difficult catheterization of Vater’s ampulla are known. It has been suggested to discontinue the diagnostic endoscopic retrograde ascending cholangiopancreatography and replace it with endoscopic ultrasonography due to possible and potentially dangerous complications. Endoscopic ultrasonography has sensitivity of 94% and specificity of 95% regardless of gallstone diameter, as opposed to magnetic resonance cholangiography. However, both of these parameters depend on the experience of the performing physician. The use of endoscopic ultrasonography allows to limit the number of performed endoscopic retrograde cholangiopancreatography procedures by more than 2/3. Ascending endoscopic retrograde cholangiopancreatography combined with an endoscopic incision into the Vater’s ampulla followed by a mechanical evacuation of stone deposits from the ducts still remains a golden standard in the treatment of choledocholithiasis. Despite some limitations such as potentially increased treatment costs as well as the necessity of the procedure to be performed by a surgeon experienced in both endoscopic retrograde cholangiopancreatography as well as endoscopic ultrasonography, the diagnostic endoscopic ultrasonography followed by a simultaneous endoscopic retrograde cholangiopancreatography

    Full Text Available Esophageal perforation due to transesophageal echocardiogram (TEE during cardiac surgery is rare. A 72-year-old female underwent TEE during an operation for aortic valve replacement. Further, the patient presented hematemesis. Gastroscopy revealed an esophageal bleeding ulcer. Endoscopic therapy was successful. Although a CT scan excluded perforation, the patient became febrile, and a second gastroscopy revealed a big perforation at the site of ulcer. The patient's clinical condition required endoscopic intervention with a new OTSC® clip (Ovesco Endoscopy, Tübingen, Germany. The perforation was successfully sealed. The patient remained on intravenous antibiotics, proton pump inhibitors and parenteral nutrition for few days, followed by enteral feeding. She was discharged fully recovered 3 months later. We clearly demonstrate an effective, less invasive treatment of an esophageal perforation with a new endoscopic clip.

    Migirov, Lela; Wolf, Michael

    2015-04-01

    Myringoplasty can be technically difficult in the pediatric patients due to the narrowness of the external auditory canal and the generally small size of the ear. Moreover, temporalis fascia grafts and myringoplasties for anterior perforations are more likely to fail in children. Surgical management of anterior perforations requires total exposure of the anterior angle however a microscope may fail to provide a view of the anterior edge in most of perforations. Recently, different endoscopes are used in the performance of ear surgery in general and myringoplasty in particular. Current study aimed to investigate the outcome of transcanal microscope-assisted endoscopic myringoplasty in homogenous group of children. The medical records of 22 children were retrospectively reviewed for age, perforation size and location, surgical and audiological findings, and outcome. All myringoplasties were performed by first author with a chondro-perichondrial graft that has been harvested from the tragus and placed medial to the tympanic membrane remnants, utilizing the underlay technique and 14-mm length, 3-mm diameter, 0° and 30° endoscopes. A microscope was occasionally used for removal of the sclerotic plaques and releasing adhesions surrounding the ossicles when bimanual manipulations were needed. Surgical success was defined as a tympanic membrane with no perforation, retraction, or graft lateralization for at least 18 months following surgery. Thirteen large-, 8 medium- and 1 small-sized perforations (defined as 75, 50 or 25%, respectively, of the tympanic membrane area), of which 14 were anterior, 2 central and 6 posterior marginal, were repaired. The edges of the defect could not be visualized under a microscope due to bone overhanging or a curved or narrow EAC in 8 anterior perforations. Intact tympanic membranes and dry ears were achieved in all operated children. The audiometric air conduction level (average of 0.5-3 kHz) for the entire cohort ranged between 10-51.3 d

    The postoperative results of laparoscopic distal pancreatectomy for solid pseudopapillary neoplasm of the pancreas (SPN), including the effects of spleen-preserving resection, are still to be elucidated. Of the 139 patients who underwent laparoscopic pancreatectomy for non-cancerous tumors, 14 consecutive patients (average age, 29.6 years; 1 man, 13 women) with solitary SPN who underwent laparoscopic distal pancreatectomy between March 2004 and June 2015 were enrolled. The tumors had a mean diameter of 4.8 cm. Laparoscopic spleen-preserving distal pancreatectomy was performed in eight patients (spleen-preserving group), including two cases involving pancreatic tail preservation, and laparoscopic spleno-distal pancreatectomy was performed in six patients (standard resection group). The median operating time was 317 min, and the median blood loss was 50 mL. Postoperatively, grade B pancreatic fistulas appeared in two patients (14.3%) but resolved with conservative treatment. No patients had postoperative complications, other than pancreatic fistulas, or required reoperation. The median postoperative hospital stay was 11 days, and the postoperative mortality was zero.None of the patients had positive surgical margins or lymph nodes with metastasis. The median follow-up period did not significantly differ between the two groups (20 vs 39 months, P = 0.1368). All of the patients are alive and free from recurrent tumors without major late-phase complications. Laparoscopic distal pancreatectomy might be a suitable treatment for patients with SPN. A spleen-preserving operation is preferable for younger patients with SPN, and this study demonstrated the non-inferiority of the procedure compared to spleno-distal pancreatectomy. © 2015 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

    2011-01-01

    Percutaneous endoscopic gastrostomy (PEG) can improve nutritional status and reduce the amount of time needed to feed neurologically impaired children. We evaluated the characteristics, complications, and outcomes of neurologically impaired children treated with PEG. We retrospectively reviewed the records of 32 neurologically impaired children who underwent PEG between March 2002 and August 2008 at our medical center. Forty-two PEG procedures comprising 32 PEG insertions and 10 PEG exchanges, were performed. The mean follow-up time was 12.2 (6.6) months. Mean patient age was 9.4 (4.5) years. The main indications for PEG insertion were swallowing difficulty with GI bleeding due to nasogastric tube placement and/or the presence of gastroesophageal reflux disease (GERD). The overall rate of complications was 47%, with early complications evident in 25% of patients and late complications in 22%. The late complications included one gastro-colic fistula, two cases of aggravated GERD, and four instances of wound infection. Among the 15 patients with histological evidence of GERD before PEG, 13 (87%) had less severe GERD, experienced no new aspiration events, and showed increased body weight after PEG treatment. PEG is a safe, effective, and relatively simple technique affording long-term enteral nutritional support in neurologically impaired children. Following PEG treatment, the body weight of most patients increased and the levels of vomiting, GI bleeding, and aspiration fell. We suggest that PEG with post-procedural observation be considered for enteral nutritional support of neurologically impaired children.

    A couple of minimally-invasive, endoscopic antireflux procedures have been developed during the last years. Beside endoscopic suturing these included injection/implantation technique of biopolymers and application of radiofrequency. Radiofrequency (Stretta) has proved only a very modest effect, while implantation techniques have been abandoned due to lack of long-term efficacy (Gatekeeper) or serious side effects (Enteryx). While first generation endoluminal suturing techniques (EndoCinch, ESD) demonstrated a proof of principle their lack of durability, due to suture loss, led to the development of a potentially durable transmural plication technique (Plicator). In a prospective-randomized, sham-controlled trial the Plicator procedure proved superiority concerning reflux symptoms, medication use and esophageal acid exposure (24-h-pH-metry). While long-term data have to be awaited to draw final conclusions, technical improvements will drive innovation in this field.

    Full Text Available Abstract Introduction This case report describes an esophagojejunal anastomotic leak following total gastrectomy for gastric cancer. The leak was treated successfully with endoscopic application of n-butyl-2-cyanoacrylate. This is the first case report on the endoscopic application of cyanoacrylate alone for the treatment of an anastomotic leak. Case presentation This report describes a case of a 68-year-old Caucasian man who underwent surgery for gastric cancer. He underwent total gastrectomy and esophagojejunal anastomosis with Roux-en-Y anastomosis plus transverse colectomy. An anastomotic leak was treated conservatively at first for a total of three weeks. However, the leak persisted; therefore, the decision was made to apply topical endoscopic n-butyl-2-cyanoacrylate. Conclusion The endoscopic application of n-butyl-2-cyanoacrylate alone can be used successfully to treat esophagojejunal anastomotic leakage.

Os pacientes foram submetidos a tratamento cirúrgico paliativo, com vesicostomia temporária e, posteriormente, definitivo, pela fulguração endoscópica das válvulas. Ambos evoluíram com função renal normal. Comentários: a válvula da uretra anterior é anomalia rara que deve ser considerada em meninos com quadro radiológico pré-natal sugestivo de obstrução infravesical, secundariamente à hipótese mais comum de válvula da uretra posterior. Ressaltamos a utilização da vesicostomia como derivação urinária temporária nestes casos, prevenindo potenciais complicações pela manipulação da uretra do recém-nascido.Objective: to discuss clinical signs, diagnostic tools and therapeutics of anterior urethral valves, an obstructive anomaly of the urinary system in males. Description: signs of urinary tract obstruction were identified on pre-natal ultrasound in two male fetuses and the diagnosis of anterior urethral valves was made through post-natal evaluation. As an initial treatment, vesicostomy was performed in both patients. Later, the valves were fulgurated using an endoscopic procedure. During the follow-up period both patients presented normal renal function. Comments: anterior urethral valves are a rare form of urethral anomaly that must be ruled out in boys with pre-natal ultrasound indicating infravesical obstruction. Vesicostomy used as an initial treatment rather than transurethral fulguration may prevent potential complications that can occur due to the small size of the neonatal urethra.

    2008-09-01

    The extremely poor outcome in patients with cholangiocarcinoma, in large part, reflects the late presentation of these tumors and the challenging nature of establishing a tissue diagnosis. Establishing a diagnosis of cholangiocarcinoma requires obtaining evidence of malignancy from sampling of the epithelium of the biliary tract, which has proven to be challenging. Although endoscopic ultrasound-guided fine needle aspiration performs slightly better than endoscopic retrograde cholangiopancreatography in diagnosing cholangiocarcinoma, both endoscopic approaches demonstrate disappointing performance characteristics.

    Endoscopic mucosal resection (EMR) has emerged for evaluation and treatment of esophageal nodules. We report our initial experience with EMR for T staging and management of early esophageal cancer. We reviewed patients undergoing EMR for esophageal adenocarcinoma between 2008 and 2013. The primary outcome measure was needed for esophagectomy. Secondary outcomes included complete eradication of adenocarcinoma, recurrence or persistence of cancer, nodal status for those undergoing esophagectomy, and complications of endoscopic treatment. During the study period, 24 patients underwent EMR demonstrating carcinoma, and a grossly margin negative endoscopic resection was achieved in all cases. Ten patients (42 %) had evidence of submucosal invasion and were referred for esophagectomy. Patients with margin negative EMR (n = 10, 42 %) or positive radial margins (n = 4, 16 %) underwent endoscopic surveillance and treatment with radiofrequency ablation or repeat EMR as needed. Thirteen patients (93 %) with intramucosal cancer (IMC) have been successfully managed with ongoing endoscopic surveillance and treatment with a median follow-up of 15.5 months. One patient underwent esophagectomy due to recurrent IMC in the setting of long-segment multifocal high-grade dysplasia. There were no esophageal perforations, one patient developed a self-limited gastrointestinal hemorrhage following EMR, and one had an esophageal stricture following endoscopic management. IMC can be successfully managed endoscopically and thus esophagectomy is avoided in a significant proportion of patients. Endoscopic management may be utilized in the setting of complete resection or radial margin involvement without evidence of submucosal invasion. Close endoscopic follow-up is of paramount importance even in those with negative margins, because recurrent disease may occur following EMR in these patients.

    Full Text Available OBJECTIVES: Access to the pterygopalatine fossa is very difficult due to its complex anatomy. Therefore, an open approach is traditionally used, but morbidity is unavoidable. To overcome this problem, an endoscopic endonasal approach was developed as a minimally invasive procedure. The surgical aim of the present study was to evaluate the utility of the endoscopic endonasal approach for the management of both benign and malignant tumors of the pterygopalatine fossa. METHOD: We report our experience with the endoscopic endonasal approach for the management of both benign and malignant tumors and summarize recent recommendations. A total of 13 patients underwent surgery via the endoscopic endonasal approach for pterygopalatine fossa masses from 2014 to 2016. This case group consisted of 12 benign tumors (10 juvenile nasopharyngeal angiofibromas and two schwannomas and one malignant tumor. RESULTS: No recurrent tumor developed during the follow-up period. One residual tumor (juvenile nasopharyngeal angiofibroma that remained in the cavernous sinus was stable. There were no significant complications. Typical sequelae included hypesthesia of the maxillary nerve, trismus, and dry eye syndrome. CONCLUSION: The low frequency of complications together with the high efficacy of resection support the use of the endoscopic endonasal approach as a feasible, safe, and beneficial technique for the management of masses in the pterygopalatine fossa.

    To establish a safe and effective endoscopic technique for collection of liver biopsy specimens from lizards by use of a 2.7-mm rigid endoscope system that is commonly available in zoologic veterinary practice. Prospective study. 11 subadult male green iguanas (Iguana iguana). Each lizard was anesthetized, and right-sided coelioscopic examination of the right liver lobe and gallbladder was performed. Three liver biopsy specimens were collected from each lizard by use of a 2.7-mm rigid endoscope and 1.7-mm (5-F) biopsy forceps. Biopsy samples were evaluated histologically for quality and crush artifact. Ten days following surgery, all iguanas were euthanatized and underwent full necropsy examination. For all 11 iguanas, the right liver lobe and gallbladder were successfully examined endoscopically, and 3 biopsy specimens of the liver were collected without complications. Mean +/- SD durations of anesthesia and surgery were 24 +/- 7 minutes and 6.8 +/- 1.0 minutes, respectively. At necropsy, there was no evidence of trauma or disease associated with the skin or muscle entry sites, liver, or any visceral structures in any iguana. All 33 biopsy specimens were considered acceptable for histologic interpretation; in most samples, the extent of crush artifact was considered minimal. By use of a 2.7-mm rigid endoscope, liver biopsy procedures can be performed safely, swiftly, and easily in green iguanas. Biopsy specimens obtained by this technique are suitable for histologic examination. For evaluation of the liver and biopsy specimen collection in lizards, endoscopy is recommended.

    In recent years, some Chinese doctors have proposed a new concept, gallstone removal without gallbladder excision, along with transition of the medical model. As there is no specialized endoscope for gallstone removal without gallbladder excision, we designed and produced a new series of gallbladder endoscopes and accessories that have already been given a Chinese invention patent (No. ZL200810199041.2). The design of these gallbladder endoscopes was based on the anatomy and physiology of the gallbladder, characteristics of gallbladder disease, ergonomics, and industrial design. This series of gallbladder endoscopes underwent clinical trials in two hospitals appointed by the State Administration of Traditional Chinese Medicine. The clinical trials showed that surgeries of gallstones, gallbladder polyps, and cystic duct calculus could be smoothly performed with these products. In summary, this series of gallbladder endoscopes is safe, reliable, and effective for gallstone removal without gallbladder excision. This note comprehensively introduces the research and design of this series of gallbladder endoscopes.

    Synchronous/metachronous gastric epithelial neoplasias (GENs) in the remaining lesion can develop at sites other than the site of endoscopic resection. In the present study, we aimed to investigate the predictive value of serum pepsinogen for detecting multiple GENs in patients who underwent endoscopic resection. In total, 228 patients with GEN who underwent endoscopic resection and blood collection for pepsinogen I and II determination were evaluated retrospectively. The mean period of endoscopic follow-up was 748.8±34.7 days. Synchronous GENs developed in 46 of 228 (20.1%) and metachronous GENs in 27 of 228 (10.6%) patients during the follow-up period. Multiple GENs were associated with the presence of pepsinogen I <30 ng/mL (p<0.001). Synchronous GENs were associated with the presence of pepsinogen I <30 ng/mL (p<0.001). Low pepsinogen I levels predict multiple GENs after endoscopic resection, especially synchronous GENs. Cautious endoscopic examination prior to endoscopic resection to detect multiple GENs should be performed for these patients.

    Full Text Available Pigmented villonodular synovitis (PVNS is a rare, benign, but a locally aggressive tumor. It is characterized by the proliferation of synovial membrane, but it can also be seen in tendon sheaths and bursae. Clinical presentation of solitary lesions include compression and locking of the joint suggesting loose bodies in the joint and a subsequent findings of an effusion, whereas diffuse lesions manifest with pain and chronic swelling. In this article, we presented a curious case of PVNS in a female patient who have been followed up due to an acetabular cystic lesion. She underwent total hip arthroplasty for severe osteoarthritis of the hip joint and associated pain. The diagnosis of PVNS was established intraoperatively.

    Management of subepithelial tumors (SETs) remains challenging. Endoscopic ultrasound (EUS) has improved differential diagnosis of these tumors but a definitive diagnosis on EUS findings alone can be achieved in the minority of cases. Complete endoscopic resection may provide a reasonable approach for tissue acquisition and may also be therapeutic in case of malignant lesions. Small SET restricted to the submucosa can be removed with established basic resection techniques. However, resection of SET arising from deeper layers of the gastrointestinal wall requires advanced endoscopic methods and harbours the risk of perforation. Innovative techniques such as submucosal tunneling and full thickness resection have expanded the frontiers of endoscopic therapy in the past years. This review will give an overview about endoscopic resection techniques of SET with a focus on novel methods.

  3. Minimally invasive percutaneous endoscopic discectomy and drainage for infectious spondylodiscitis

    2013-08-01

    Full Text Available The primary goals for treating infectious spondylodiscitis are to make an accurate diagnosis, isolate the causative organism, and prescribe effective antibiotic therapy based on the culture data. A positive culture of the responsible organism is not required for diagnosis, although it is extremely important for successful treatment and prevention of further morbidity. Surgical intervention is usually reserved for cases that are unresponsive to antibiotic therapy and for patients who have developed progressive spinal deformity or instability, epidural abscesses, or neurological impairment. However, the incidence of perioperative morbidity is particularly increased in elderly patients or in those with poor general condition. With improved endoscopic instruments and techniques, our clinical experiences demonstrate that spinal infections can be successfully treated by minimally invasive percutaneous endoscopic debridement. Direct endoscopic observation and collection of sufficient quantities of samples for microbiological examinations from the infected region are usually possible. This article summarizes the diagnostic and therapeutic values of percutaneous endoscopic discectomy and drainage (PEDD used to treat patients with spondylodiscitis. Our clinical evidence-based survey suggests that PEDD can provide adequate retrieval of specimens and has high diagnostic efficacy, thereby enabling prompt and sensitive antibiotic therapy to the offending pathogens. We propose that PEDD is an effective alternative for treating infectious spondylodiscitis and should be considered prior to extensive anterior surgery in selected cases. This method is particularly suitable for patients with early-stage spinal infection or serious medical conditions.

    BACKGROUND: Objectives were two. (1) to determine theefficiency of the endoscopic injection therapy (EIT) in patients suffering from bleeding caused by peptic ulcer disease with high risk of recurrence, and (2) to recognize clinical and endoscopical risk factors that influence recurrence of hemorrhage and mortality from this pathology. METHODS: This is a retrospective study that included 121 patients, who were admitted by a unit specialized in managing gastrointestinal hemorrhage owing to peptic ulcer with active bleeding or non-bleeding visible vessel, and who underwent EIT with epinephrine between March, 1994 and February, 1996.RESULTS: Initial success was achieved in 119 patients who underwent EIT (99,1%). Bleeding persisted in one patient (0,9%), and in another one, EIT was not sucessful because of inaccessible location. Definite hemostasis was achieved in 93 patients (77,5%) and there was recurrence in 28 cases (23,5%). Twenty-six patients underwent surgical therapy (21,5%). The univariable analysis showed that hemorrhage recurrence was related to the presence of shock (p = 0,002), hematemesis (p = 0,2), age over 60 (p = 0,009), number of blood units transfused (p = 0,00000) and ulcer diameter larger than 2 cm (p = 0,018). The global mortality in our patients was of 10%, and surgical mortality was of 34,6%. Factors significantly related to mortality were hemorrhage recurrence (p = 0,000003), presence of concomitant disease (p = 0,05), and presence of gastric ulcer (p = 0,021), in addition to age (over 60), presence of shock and ulcer diameter larger than 2 cm (p = 0,05).CONCLUSION: EIT is a valuable procedure for the treatment of hemorrhage caused by peptic ulcer with high risk of recurrence (active hemorrhage or visible vessel), with a definite hemostasis of 77,5%. The presence of shock, hematemesis, age over 60, transfusion requirements of more than 3 blood units, and ulcer diameter of more than 2 cm are factors that increase the probability of hemorrhage

    Breast conserving therapy (BCT) now is widely accepted in Japan. Quadrantectomy has been chosen from among the several available breast conserving operations for its minimal recurrence rate. Quadrantectomy, or excision of one-quarter volume of the breast, leaves a moderate degree of deformity which diminishes the quality of life. The authors have introduced immediate post-ectomy breast reconstruction utilizing an endoscopically harvested latissimus dorsi (LD) muscle flap which results in a minimal donor site scar. Five cases of endoscope-assisted LD muscle reconstruction of a quadrantectomized breast have been followed by irradiation therapy. Prior to reconstruction, with the patient in the supine position, quadrantectomy and dissection of axillary lymphnodes are performed through an incision extending from the anterior axillary to the inflamammary line. The patient then is placed in the lateral supine position. LD muscle flap dissection by electrocautery begins through the initial incision. Dissections of posterior portions of the muscle continue, under endoscopic visualization, through one or two ports along the anterior margin of the muscle. Moderate amount of adipose tissue is left attached to the muscle to obtain full augmentation. The raised flap then is transferred and secured to the post-quandrantectomy defect. Some post-irradiation shrinkage of the inserted LD muscle has been a common occurrence of breast reconstruction. An ample amount of adipose tissue left attached to the muscle margin will solve this matter since fatty tissue is more resistant to post-irradiation atrophy. (J.P.N.)

    To identify the most effective endoscopic biliary drainage technique for patients with hilar cholangiocarcinoma. In total, 118 patients with hilar cholangiocarcinoma underwent endoscopic management [endoscopic nasobiliary drainage (ENBD) or endoscopic biliary stenting] as a temporary drainage in our institution between 2009 and 2014. We retrospectively evaluated all complications from initial endoscopic drainage to surgery or palliative treatment. The risk factors for biliary reintervention, post-endoscopic retrograde cholangiopancreatography (post-ERCP) pancreatitis, and percutaneous transhepatic biliary drainage (PTBD) were also analyzed using patient- and procedure-related characteristics. The risk factors for bilateral drainage were examined in a subgroup analysis of patients who underwent initial unilateral drainage. In total, 137 complications were observed in 92 (78%) patients. Biliary reintervention was required in 83 (70%) patients. ENBD was significantly associated with a low risk of biliary reintervention [odds ratio (OR) = 0.26, 95%CI: 0.08-0.76, P = 0.012]. Post-ERCP pancreatitis was observed in 19 (16%) patients. An absence of endoscopic sphincterotomy was significantly associated with post-ERCP pancreatitis (OR = 3.46, 95%CI: 1.19-10.87, P = 0.023). PTBD was required in 16 (14%) patients, and Bismuth type III or IV cholangiocarcinoma was a significant risk factor (OR = 7.88, 95%CI: 1.33-155.0, P = 0.010). Of 102 patients with initial unilateral drainage, 49 (48%) required bilateral drainage. Endoscopic sphincterotomy (OR = 3.24, 95%CI: 1.27-8.78, P = 0.004) and Bismuth II, III, or IV cholangiocarcinoma (OR = 34.69, 95%CI: 4.88-736.7, P < 0.001) were significant risk factors for bilateral drainage. The endoscopic management of hilar cholangiocarcinoma is challenging. ENBD should be selected as a temporary drainage method because of its low risk of complications.

    Several outbreaks of severe infections due to contamination of gastrointestinal (GI) endoscopes, mainly duodenoscopes, have been described. The rate of microbial endoscope contamination varies dramatically in literature. The aim of this multicentre prospective study was to evaluate the hygiene quality of endoscopes and automated endoscope reprocessors (AERs) in Tyrol/Austria. In 2015 and 2016, a total of 463 GI endoscopes and 105 AERs from 29 endoscopy centres were analysed by a routine (R) and a combined routine and advanced (CRA) sampling procedure and investigated for microbial contamination by culture-based and molecular-based analyses. The contamination rate of GI endoscopes was 1.3%-4.6% according to the national guideline, suggesting that 1.3-4.6 patients out of 100 could have had contacts with hygiene-relevant microorganisms through an endoscopic intervention. Comparison of R and CRA sampling showed 1.8% of R versus 4.6% of CRA failing the acceptance criteria in phase I and 1.3% of R versus 3.0% of CRA samples failing in phase II. The most commonly identified indicator organism was Pseudomonas spp., mainly Pseudomonas oleovorans. None of the tested viruses were detected in 40 samples. While AERs in phase I failed (n = 9, 17.6%) mainly due to technical faults, phase II revealed lapses (n = 6, 11.5%) only on account of microbial contamination of the last rinsing water, mainly with Pseudomonas spp. In the present study the contamination rate of endoscopes was low compared with results from other European countries, possibly due to the high quality of endoscope reprocessing, drying and storage.

    Full Text Available Purpose: Percutaneous endoscopic gastrostomy (PEG can improve nutritional status and reduce the amount of time needed to feed neurologically impaired children. We evaluated the characteristics, complications, and outcomes of neurologically impaired children treated with PEG. Methods: We retrospectively reviewed the records of 32 neurologically impaired children who underwent PEG between March 2002 and August 2008 at our medical center. Forty-two PEG procedures comprising 32 PEG insertions and 10 PEG exchanges, were performed. The mean follow-up time was 12.2 (6.6 months. Results: Mean patient age was 9.4 (4.5 years. The main indications for PEG insertion were swallowing difficulty with GI bleeding due to nasogastric tube placement and/or the presence of gastroesophageal reflux disease (GERD. The overall rate of complications was 47%, with early complications evident in 25% of patients and late complications in 22%. The late complications included one gastro-colic fistula, two cases of aggravated GERD, and four instances of wound infection. Among the 15 patients with histological evidence of GERD before PEG, 13 (87% had less severe GERD, experienced no new aspiration events, and showed increased body weight after PEG treatment. Conclusion: PEG is a safe, effective, and relatively simple technique affording long-term enteral nutritional support in neurologically impaired children. Following PEG treatment, the body weight of most patients increased and the levels of vomiting, GI bleeding, and aspiration fell. We suggest that PEG with post-procedural observation be considered for enteral nutritional support of neurologically impaired children.

    Background: Endoscopic sphincterotomy (ES) carries a substantial risk of recurrent choledocholithiasis but retreatment with endoscopic retrograde cholangiopancreatography (ERCP) is safe and feasible. However, long term results of repeat ERCP and risk factors for late complications are largely unknown. Aims: To investigate the long term outcome of repeat ERCP for recurrent bile duct stones after ES and to identify risk factors predicting late choledochal complications. Methods: Eighty four patients underwent repeat ERCP, combined with ES in 69, for post-ES recurrent choledocholithiasis. Long term outcomes of repeat ERCP were retrospectively investigated and factors predicting late complications were assessed by multivariate analysis. Results: Complete stone clearance was achieved in all patients. Forty nine patients had no visible evidence of prior sphincterotomy. Two patients experienced early complications. During a follow up period of 2.2–26.0 years (median 10.9 years), 31 patients (37%) developed late complications, including stone recurrence (n = 26), acute acalculous cholangitis(n = 4), and acute cholecystitis (n = 1). There were neither biliary malignancies nor deaths attributable to biliary disease. Multivariate analysis identified three independent risk factors for choledochal complications: interval between initial ES and repeat ERCP ⩽5 years, bile duct diameter ⩾15 mm, and periampullary diverticulum. Choledochal complications were successfully treated with repeat ERCP in 29 patients. Conclusions: Choledochal complications after repeat ERCP are relatively frequent but are endoscopically manageable. Careful follow up is necessary, particularly for patients with a dilated bile duct, periampullary diverticulum, or early recurrence. Repeat ERCP is a reasonable treatment even for recurrent choledocholithiasis after ES. PMID:15542528

    OBJECTIVE Endoscopic third ventriculostomy with choroid plexus cauterization (ETV/CPC) offers an alternative to shunt treatment for infantile hydrocephalus. Diagnosing treatment failure is dependent on infantile hydrocephalus metrics, including head circumference, fontanel quality, and ventricle size. However, it is not clear to what degree these metrics should be expected to change after ETV/CPC. Using these clinical metrics, the authors present and analyze the decision making in cases of ETV/CPC failure. METHODS Infantile hydrocephalus metrics, including bulging fontanel, head circumference z-score, and frontal and occipital horn ratio (FOHR), were compared between ETV/CPC failures and successes. Treatment outcome predictive values of metrics individually and in combination were calculated. RESULTS Forty-four patients (57% males, median age 1.2 months) underwent ETV/CPC for hydrocephalus; of these patients, 25 (57%) experienced failure at a median time of 51 days postoperatively. Patients experiencing failure were younger than those experiencing successful treatment (0.8 vs 3.9 months, p = 0.01). During outpatient follow-up, bulging anterior fontanel, progressive macrocephaly, and enlarging ventricles each demonstrated a positive predictive value (PPV) of no less than 71%, but a bulging anterior fontanel remained the most predictive indicator of ETV/CPC failure, with a PPV of 100%, negative predictive value of 73%, and sensitivity of 72%. The highest PPVs and specificities existed when the clinical metrics were present in combination, although sensitivities decreased expectedly. Only 48% of failures were diagnosed on the basis all 3 hydrocephalus metrics, while only 37% of successes were negative for all 3 metrics. In the remaining 57% of patients, a diagnosis of success or failure was made in the presence of discordant data. CONCLUSIONS Successful ETV/CPC for infantile hydrocephalus was evaluated in relation to fontanel status, head growth, and change in

    Abstract Although endoscopic ultrasonography (EUS) is the first-choice imaging modality for predicting the invasion depth of early gastric cancer (EGC), the prediction accuracy of EUS is significantly decreased when EGC is combined with ulceration. The aim of present study was to compare the accuracy of EUS and conventional endoscopy (CE) for determining the depth of EGC. In addition, the various clinic-pathologic factors affecting the diagnostic accuracy of EUS, with a particular focus on endoscopic ulcer shapes, were evaluated. We retrospectively reviewed data from 236 consecutive patients with ulcerative EGC. All patients underwent EUS for estimating tumor invasion depth, followed by either curative surgery or endoscopic treatment. The diagnostic accuracy of EUS and CE was evaluated by comparing the final histologic result of resected specimen. The correlation between accuracy of EUS and characteristics of EGC (tumor size, histology, location in stomach, tumor invasion depth, and endoscopic ulcer shapes) was analyzed. Endoscopic ulcer shapes were classified into 3 groups: definite ulcer, superficial ulcer, and ill-defined ulcer. The overall accuracy of EUS and CE for predicting the invasion depth in ulcerative EGC was 68.6% and 55.5%, respectively. Of the 236 patients, 36 patients were classified as definite ulcers, 98 were superficial ulcers, and 102 were ill-defined ulcers, In univariate analysis, EUS accuracy was associated with invasion depth (P = 0.023), tumor size (P = 0.034), and endoscopic ulcer shapes (P = 0.001). In multivariate analysis, there is a significant association between superficial ulcer in CE and EUS accuracy (odds ratio: 2.977; 95% confidence interval: 1.255–7.064; P = 0.013). The accuracy of EUS for determining tumor invasion depth in ulcerative EGC was superior to that of CE. In addition, ulcer shape was an important factor that affected EUS accuracy. PMID:27472672

  13. Rare Endoscopic Manifestation of Pancreatic Adenocarcinoma

    Full Text Available Gastric ulcer secondary to direct invasion from pancreatic adenocarcinoma is rare. Metastases to the stomach have been commonly reported with melanoma and with primary tumors of the breast, lung, ovary, liver, colon and testis. We report a patient who presented with epigastric pain and in whom subsequently upper endoscopy showed a malignant gastric ulcer secondary to direct invasion from pancreatic adenocarcinoma of the body. An 81-year-old female presented to our hospital with epigastric pain and subsequently underwent endoscopy with endoscopic ultrasound for evaluation of a pancreatic body mass. She had a large gastric ulcer in the fundus which was in direct continuity with the pancreatic mass. Pathology from biopsy of the ulcer revealed invasive well-to-moderately-differentiated adenocarcinoma, and immunohistochemical stains were strongly positive for CA19-9, CK7, CK19 and carcinoembryonic antigen. These findings were consistent with a histopathological diagnosis of metastatic carcinoma of the pancreas. Patients with gastrointestinal metastases usually have advanced malignancy with poor prognosis. Endoscopic evaluation with adequate biopsies should be performed for symptomatic patients.

    Nasal liquorrhea indicates a cerebrospinal fluid fistula, an open communication between the intracranial cerebrospinal fluid and the nasal cavity. It can be traumatic and spontaneous. The aim of this study was to assess the outcome of endoscopic repair of cerebrospinal fluid fistula using fluorescein. This retrospective study included 30 patients of both sexes, with a mean age of 48.7 years, treated in the period from 2007 to 2015. All patients underwent lumbar administration of 5% sodium fluorescein solution preoperatively. Fistula was closed using three-layer graft and fibrin glue. Cerebrospinal fluid fistulas were commonly located in the ethmoid (37%) and sphenoid sinus (33%). Most patients presented with traumatic cerebrospinal fluid fistulas (2/3 of patients). The reported success rate for the first repair attempt was 97%. Complications occurred in three patients: one patient presented with acute hydrocephalus, one with reversible encephalopathy syndrome on the fifth postoperative day with bilateral loss of vision, and one patient was diagnosed with hydrocephalus two years after the repair of cerebrospinal fluid fistula. Endoscopic diagnosis and repair of cerebrospinal fluid fistulas using fluorescein intrathecally has high success rate and low complication rate.

    There has been a gradual introduction of transanal endoscopic microsurgery (TEM) into UK practice although the uptake remains variable. This study aimed to assess the availability, application and referral pattern of TEM amongst colorectal surgeons. A questionnaire was sent to all consultant members of the Association of Coloproctology. This considered their practice, the availability, application and referral pattern for TEM, and their views on application regarding a selection of rectal tumour scenarios. There were 142 replies representing 116 hospitals and 297 colorectal surgeons. The median catchment area was 280,000 (range 70,000-1,000,000). TEM was available in 18% of hospitals and 72% either performed or referred patents for TEM. Of 21 units performing TEM, 15 received referrals. From 305 TEM procedures performed over the previous year, 206 were referred cases. Eighty-five per cent of consultants considered TEM a necessary technique for optimum management of rectal lesions. Although 61% of consultants considered endoanal excision optimal for low benign rectal tumours, 58% said TEM was optimal for midrectal lesions and between 30% and 55% for high rectal lesions depending if the tumour position was anterior or posterior, respectively. One-third of consultants would perform TEM for a low T1 rectal carcinoma although half would proceed to anterior resection. TEM is considered to have a significant role in the optimal management of rectal lesions. The presence of the technique in a limited number of hospitals does appear to provide adequate resources although audit should continue to be centralized.

    The diagnosis and staging of various gastrointestinal malignancies have been made possible with the use of endoscopic ultrasound, which is a relatively safe procedure. The field of endoscopic ultrasound is fast expanding due to advancements in therapeutic endoscopic ultrasound. Though various...... studies have established its role in gastrointestinal malignancies and pancreatic conditions, its potential in the field of hepatic lesions still remains vastly untapped. In this paper the authors attempt to review important and landmark trials, case series and case studies involving hepatic applications...

    To determine success rates, predictors of recurrence, and recurrence management of patients treated for short anterior urethral strictures by direct vision internal urethrotomy (DVIU). We identified 128 patients who underwent DVIU of the anterior urethra between December 2009 and March 2016. Follow-up was conducted by telephone interviews. Success rates were assessed by Kaplan-Meier estimators. Predictors of stricture recurrence and different further therapy strategies were identified by uni- and multivariable Cox regression analyses. The mean age was 63.8 years (standard deviation: 16.3) and the overall success rate was 51.6% (N = 66) at a median follow-up of 16 months (interquartile range: 6-43). Median time to stricture recurrence was six months (interquartile range: 2-12). In uni- and multivariable analyses, only repeat DVIU (hazard ratio [HR] = 1.87, 95% confidence interval (CI) = 1.13-3.11, P= .015; and HR=1.78, 95% CI = 1.05-3.03, P = .032, respectively) was a risk factor for recurrence. Of 62 patients with recurrence, 35.5% underwent urethroplasty, 29% underwent further endoscopic treatment, and 33.9% did not undergo further interventional therapy. Age (HR = 1.05, 95% CI = 1.01-1.09, P = .019) and diabetes (HR = 2.90, 95% CI = 1.02-8.26, P = .047) were predictors of no further interventional therapy. DVIU seems justifiable in short urethral strictures as a primary treatment. Prior DVIU was a risk factor for recurrence. In case of recurrence, about one-third of the patients did not undergo any further therapy. Higher age and diabetes predicted the denial of any further treatment. Copyright © 2017 Elsevier Inc.

    Full Text Available A 41-year-old female with a history of uterine cancer and Celiac and Raynaud’s Disease presented to our institution with frequent migraines and nasal congestion. She underwent functional endoscopic sinus surgery (FESS and experienced acute unilateral vision loss postoperatively. Rapid recognition of the etiology and effective treatment are paramount given the permanent and irreversible vision loss that can result. Arterial vasospasm following FESS is rare. Patients with autoimmune diseases have perhaps an increased risk for vasospasm secondary to an increased vasoreactive profile. We present the first documented case of nitroglycerin sublingual therapy to successfully treat ophthalmic artery vasospasm following FESS. Nitroglycerin sublingual therapy is a promising treatment for ophthalmic vasospasm secondary to its ability to cross the blood-ocular barrier, its rapid onset of action, and its ability to promote relaxation of vascular smooth muscle.

    Postpneumonectomy syndrome is characterized by postoperative bronchial obstruction caused by mediastinal shift. The syndrome is well documented in the medical literature as a late complication of right pneumonectomy; however, it rarely occurs following resection of the left lung, and only 10 cases have been published. The pathophysiology, clinical manifestations, prognosis, and treatment are similar for both sides of the lung. We present the case of an adult patient who underwent left pneumonectomy and developed postpneumonectomy syndrome 15 months later. Stenosis of the intermediate bronchus occurred between the vertebral body and the right pulmonary artery. Endoscopic treatment with a self-expanding metal stent was successful, and complete remission was observed over the 6 months of follow-up.

    As part of the clinical evaluation of image management and communications system (IMACS), the authors undertook a prospective study to compare conventional film versus digitized film viewed on a workstation. Twenty-five each of normal and abnormal endoscopic retrograde cholangiopancreatographic (ERCP) studies were digitized with a 1,684 x 2,048-pixel matrix and evaluated in a single-blind fashion on the workstation. The resulting interpretations were then compared with those resulting from interpretation of film (spot film and 100-mm photospot) images. They report that no significant differences were found in ability to see anatomic detail or pathology. A second study involved performing 10 ERCP studies in a lithotripsy suite equipped with biplane digital fluoroscopy. The digital video displays were comparable in quality to that of film. Progress is being made in using the IMACS for archiving and retrieval of all current ERCP images

    Full Text Available Endoscopic third ventriculostomy (ETV is considered as a treatment of choice for obstructive hydrocephalus. It is indicated in hydrocephalus secondary to congenital aqueductal stenosis, posterior third ventricle tumor, cerebellar infarct, Dandy-Walker malformation, vein of Galen aneurism, syringomyelia with or without Chiari malformation type I, intraventricular hematoma, post infective, normal pressure hydrocephalus, myelomeningocele, multiloculated hydrocephalus, encephalocele, posterior fossa tumor and craniosynostosis. It is also indicated in block shunt or slit ventricle syndrome. Proper Pre-operative imaging for detailed assessment of the posterior communicating arteries distance from mid line, presence or absence of Liliequist membrane or other membranes, located in the prepontine cistern is useful. Measurement of lumbar elastance and resistance can predict patency of cranial subarachnoid space and complex hydrocephalus, which decides an ultimate outcome. Water jet dissection is an effective technique of ETV in thick floor. Ultrasonic contact probe can be useful in selected patients. Intra-operative ventriculo-stomography could help in confirming the adequacy of endoscopic procedure, thereby facilitating the need for shunt. Intraoperative observations of the patent aqueduct and prepontine cistern scarring are predictors of the risk of ETV failure. Such patients may be considered for shunt surgery. Magnetic resonance ventriculography and cine phase contrast magnetic resonance imaging are effective in assessing subarachnoid space and stoma patency after ETV. Proper case selection, post-operative care including monitoring of ICP and need for external ventricular drain, repeated lumbar puncture and CSF drainage, Ommaya reservoir in selected patients could help to increase success rate and reduce complications. Most of the complications develop in an early post-operative, but fatal complications can develop late which indicate an importance of

    An increasing number of experimental beating heart animal studies describe simple transapical mitral valve repairs based on the direct endoscopic visualization of the left ventricle. The aim of our human cadaveric study was to develop a method for more complex transapical endoscopic procedures by on-pump heart operations. After preparation of 20 human fresh cadavers, a standard left anterolateral minithoracotomy was performed in the fifth intercostal space and the pericardium was entered. A rigid 0 degree endoscope and the instruments were introduced through a silicon apical port. To restore the natural form of the left heart, CO2 was insufflated. To test the mitral valve competence, the left ventricle was pressure-injected with saline after each step. After transecting the chords of the A2 segment of the anterior mitral leaflet before the experimental mitral valve repair, the tendinous chord was replaced using an especially designed clip chord. The second part of the experiment consisted of a segmental excision of the P2 segment of the posterior mitral leaflet followed by a standard valvuloplasty and suture annuloplasty. With the help of the described transapical endoscopic mitral valve repair technique, we gained direct visual information of the coaptation line of the mitral leaflets as well as the anatomy and function of the subvalvular apparatus. Using intracardiac imaging, we could perform successful transapical complex mitral repair in each case. The minimally invasive transapical endoscopic method has the potential to offer advantages for on-pump mitral valve repair procedures even in complex mitral valve repair cases.

    The presence of ulcer in early gastric cancer (EGC) is important for the feasibility of endoscopic resection, only a few studies have examined the clinicopathological implications of endoscopic ulcer in EGC. To determine the role of endoscopic ulcer as a predictor of clinical behaviors in EGC. Data of 3,270 patients with EGC who underwent surgery between January 2005 and December 2012 were reviewed. Clinicopathological characteristics were analyzed in relation to the presence and stage of ulcer in EGC. Based on endoscopic findings, the stage of ulcer was categorized as active, healing, or scar. Logistic regression analysis was performed to analyze factors associated with lymph node metastasis (LNM). 2,343 (71.7%) patients had endoscopic findings of ulceration in EGC. Submucosal (SM) invasion, LNM, lymphovascular invasion (LVI), perineural invasion, and undifferentiated-type histology were significantly higher in ulcerative than non-ulcerative EGC. Comparison across different stages of ulcer revealed that SM invasion, LNM, and LVI were significantly associated with the active stage, and that these features exhibited significant stage-based differences, being most common at the active stage, and least common at the scar stage. The presence of endoscopic ulcer and active status of the ulcer were identified as independent risk factors for LNM. Ulcerative EGC detected by endoscopy exhibited more aggressive behaviors than non-ulcerative EGC. Additionally, the endoscopic stage of ulcer may predict the clinicopathological behaviors of EGC. Therefore, the appearance of ulcers should be carefully evaluated to determine an adequate treatment strategy for EGC.

    Twenty-seven patients with acute secondary colonic pseudoobstruction have been studied before and after endoscopic decompression of the colon. 19 patients were treated by single endoscopic decompression and 8 patients who had, or were expected to have, recurrent pseudoobstruction were treated by endoscopy-assisted introduction of a double-lumen tube into the colon. 17 out of 27 patients had massive dilatation of the right hemicolon. 19 patients completely retained stools and had a dilated colon the day before the endoscopic treatment, while 8 out of 27 patients still had passage of stool despite threatening dilatation of the colon. Initial decompression of the colon was achieved in all patients with both techniques, but cecal perforation developed in 1 patient. Normal colonic function returned in all patients who underwent single endoscopic decompression within three days, and in all patients treated with a colonic tube within 4 days (mean value). The success of endoscopic therapy of acute pseudoobstruction could not be explained by drugs administered before and after the endoscopic treatment. It is concluded that endoscopic decompression of the colon is an effective treatment for acute pseudoobstruction. Repeated colonoscopic decompression in refractory cases may be avoided by endoscopy-assisted placement of large caliber drainage tubes.

    Endoscopic full-thickness resection of gastric subepithelial tumors with a full-thickness suturing device has been described as feasible in two small case series. The aim of this study was to evaluate the efficacy, safety, and clinical outcome of this resection technique. After 31 patients underwent endoscopic full-thickness resection, the data were analyzed retrospectively. Before snare resection, 1 to 3 full-thickness sutures were placed underneath each tumor with a device originally designed for endoscopic anti-reflux therapy. All tumors were resected successfully. Bleeding occurred in 12 patients (38.7 %); endoscopic hemostasis could be achieved in all cases. Perforation occurred in 3 patients (9.6 %), and all perforations could be managed endoscopically. Complete resection was histologically confirmed in 28 of 31 patients (90.3 %). Mean follow-up was 213 days (range, 1 - 1737), and no tumor recurrences were observed. Endoscopic full-thickness resection of gastric subepithelial tumors with the suturing technique described above is feasible and effective. After the resection of gastrointestinal stromal tumors (GISTs), we did not observe any recurrences during follow-up, indicating that endoscopic full-thickness resection may be an alternative to surgical resection for selected patients. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Objectives. Recent studies suggest that histological healing is a treatment goal in ulcerative colitis (UC. We aimed to evaluate the correlation between histological activity and clinical, endoscopic, and serologic activities in patients with UC. Methods. We retrospectively reviewed medical records from patients with UC who underwent colonoscopy or sigmoidoscopy with biopsies. The Mayo endoscopic subscore was used to assess endoscopic activity. Biopsy specimens were reviewed by two blinded pathologists and scored using the Geboes scoring system. Results. We analyzed 154 biopsy specimens from 82 patients with UC. Histological scores exhibited strong correlation with endoscopic subscores (Spearman’s rank correlation coefficient r=0.774, p<0.001 and moderate correlation with C-reactive protein levels (r=0.422, p<0.001 and partial Mayo scores (r=0.403, p<0.001. Active histological inflammation (Geboes score ≥ 3.1 was observed in 6% (2 of 33 of the endoscopically normal mucosa samples, 66% (19 of 29 of mild disease samples, and 98% (90 of 92 of moderate-to-severe disease samples. Conclusions. Histological activity was closely correlated with the endoscopic, clinical, and serologic UC activities. However, several patients with mild or normal endoscopic findings exhibited histological evidence of inflammation. Therefore, histological assessment may be helpful in evaluating treatment outcomes and determining follow-up strategies.

    2017-06-01

    A retrospective cohort study was conducted to analyze the relapse rate of anterior open bite (AOB) correction comparing Le Fort I osteotomy with and without anterior segmentation. The risk factors that might contribute to relapse were also assessed. Lateral cephalograms obtained at six different times were analyzed. A total of 81 patients with AOB were recruited. Thirty-five patients underwent Le Fort I osteotomy without anterior segmentation and 46 patients underwent anterior segmentation. Le Fort I osteotomy with anterior segmentation resulted in significantly more AOB relapse when compared to that without anterior segmentation at 7 weeks postoperative (15.2% vs. 0%, P=0.016). During the early postoperative period, factors that contributed to AOB relapse in Le Fort I osteotomy with anterior segmentation were AOB closure ≥4mm and inferior positioning of the anterior segment >2mm. Over the long term, AOB closure ≥4mm and intraoral vertical ramus osteotomy as the only mandibular procedure were factors identified as causing more AOB relapse in those treated by Le Fort I osteotomy with anterior segmentation. In conclusion, Le Fort I osteotomy without anterior segmentation was found to be more stable in the surgical correction of AOB in the early and late postoperative periods.

    Full Text Available Abstract Introduction Endoscopic hemostasis for severe upper gastrointestinal bleeding due to tumors, such as gastrointestinal stromal tumors and malignant lymphoma, is temporarily effective. However, permanent hemostasis is difficult in many cases because of diffuse bleeding. Case presentation A 60-year-old Japanese woman was admitted to our hospital with hematemesis. Endoscopy revealed multiple gastric polyps and fresh blood in her stomach. One of the gastric polyps, which was associated with oozing bleeding, was found near the anterior wall of the lower gastric body. We initially applied hemostatic forceps and argon plasma coagulation over the tumor surface, but the bleeding persisted. After endoscopic mucosal resection, exposed vessels were seen at the base of the mucosal resection site with oozing bleeding. Coagulation of the bleeding vessels using hemostatic forceps allowed successful completion of the hemostatic procedure. Our patient also had eight synchronous gastric cancer lesions. Histological examination of the resected specimens showed various types of cancer. Conclusion This is a case report of gastric cancer associated with eight gastric cancer lesions, confirmed by histology, in which hemostasis was achieved through endoscopy.

    The purpose of this study was to evaluate the prevalence of anterior knee pain in anatomic double-bundle anterior cruciate ligament (ACL) reconstruction and to identify critical factors affecting postoperative anterior knee pain development. Subjects comprised 171 patients (171 knees) who underwent anatomic double-bundle ACL reconstruction with a follow-up period of ≥2 years. The procedure used bone-patellar tendon-bone plus gracilis tendon (BTB-G) in 56 knees, semitendinosus tendon (ST) in 71 knees, and ST-G in 44 knees. Clinical results and prevalence and severity of anterior knee pain were assessed at 3 months and 2 years postoperatively. Clinical variables influencing anterior knee pain development at each postoperative period were subjected to univariate analysis, followed by logistic regression analysis to identify risk factors for anterior knee pain. Overall prevalences of anterior knee pain at 3 months and 2 years postoperatively were 42.0 and 11.1%, respectively. Use of BTB-G graft represented the highest prevalence of anterior knee pain between the 3 different grafts (P = 0.001); however, this statistical significance disappeared at 2 years postoperatively. Prevalence of postoperative extension deficit was significantly higher in anterior knee pain-positive cohort than in anterior knee pain-negative cohort at 3 months postoperatively. Level of quadriceps strength was significantly lower, and Lysholm score was significantly worse in anterior knee pain-positive cohort than in anterior knee pain-negative cohort at 2 years postoperatively. According to logistic regression analysis, knee extension deficit was a predisposing factor for the development of anterior knee pain at 3 months postoperatively (odds ratio, 2.76; P = 0.004); however, there was no significant predisposing factor for anterior knee pain at 2 years postoperatively. Knee extension deficit was an important predisposing factor for postoperative anterior knee pain in the early

    Chronic Pancreatitis is a recurrent disease, frequently alcohol intake related and tend to occur in the third and the fourth decades. Stenoses and lithiasis in the main pancreatic duct causes obstruction and subsequently pain. Therefore endoscopic or surgical decompression of main pancreatic duct results in pain relief. Review our experience in the endoscopic management in patients suffering from chronic pancreatitis. 42 patients underwent ERCP for management of their chronic pancreatitis. Therapeutic options were sphincterotomy alone, prostheses and "do nothing". Follow-up was made by phone call and outpatient office visits. Mean follow-up was 47.8 (27.2) months. 22 patients underwent therapeutic ERCP. In 8 patients we performed sphincterotomy and in 14 patients, a sphincterotomy and prostheses intubation. 8 patients are asymptomatic after a mean follow-up of 10.8 (11.6) months. 2 of them, underwent sphincterotomy and six of them, underwent sphincterotomy and prostheses intubation. Therapeutic ERCP is a tool that relieves pain in a fifth of patients suffering from chronic pancreatitis.

    The success of transanal endoscopic microsurgery (TEM) for early rectal cancer depends on proper indications and strict patient selection. When unfavorable pathologic features are identified after TEM operation, total mesorectal excision is recommended to minimize the risk of recurrence. In this study, data were collected in a retrospective series of patients to determine the results of laparoscopic reoperation after TEM. All patients underwent an accurate rectal-digital examination and clinical tumor staging by transanal endosonography, CT, and/or MRI. The histologic examination included an evaluation of the free margins, depth of tumor infiltration according to International Union Against Cancer guidelines, degree of tumor differentiation, and the presence of lymphovascular and perineural invasion. When a high-risk tumor was identified, reoperation was performed within 6 weeks from TEM. The patients were divided into two groups according to the procedure performed: laparoscopic anterior resection (LAR) or laparoscopic abdominal perineal amputation (LAPR). Sixty-eight patients (5.3%) underwent reoperation: 38 underwent LAR and 30 underwent LAPR. The mean operative time was 148.24 min (± 35.8, p = 0.62). Meanwhile, the mean distance of the TEM scar from the anal verge differed statistically between the two groups (p = 0.003) and was statistically correlated with abdominal perineal amputation (p = 0.0001) in multivariate analysis. Conversion to open surgery was required in 6 patients (15.7%) in the LAR group and 3 patients (10%) in the LAPR group (p = 0.38). The histologic examination revealed residual cancer cells in 3 cases (3 pT2N0) and 1 case (1 pT3N0), respectively, and lymph node metastases in 4 cases. No residual neoplasms were detected in the remaining 60 cases (88.3%). After a mean follow-up of 108 months, the overall disease-free survival was 98% (95% CI 88-99%). In our experience, reoperation after TEM using a laparoscopic approach is

    Purpose Obstructive jaundice in patients with hepatocellular carcinoma (HCC) is uncommon (0.5-13%). Unlike other causes of obstructive jaundice, the role of endoscopic intervention in obstructive jaundice complicated by HCC has not been clearly defined. The aim of this study was to evaluate the clinical characteristics of obstructive jaundice caused by HCC and predictive factors for successful endoscopic intervention. Materials and Methods From 1999 to 2009, 54 patients with HCC who underwent endoscopic intervention to relieve obstructive jaundice were included. We defined endoscopic intervention as a clinical success when the obstructive jaundice was relieved within 4 weeks. Results Clinical success was achieved in 23 patients (42.6%). Patients in the clinical success group showed better Child-Pugh liver function (C-P grade A or B/C; 17/6 vs. 8/20), lower total bilirubin levels (8.1±5.3 mg/dL vs. 23.1±10.4 mg/dL) prior to the treatment, and no history of alcohol consumption. The only factor predictive of clinical success by multivariate analysis was low total bilirubin level at the time of endoscopic intervention, regardless of history of alcohol consumption [odds ratio 1.223 (95% confidence interval, 1.071-1.396), p=0.003]. The cut-off value of pre-endoscopic treatment total bilirubin level was 12.8 mg/dL for predicting the clinical prognosis. Median survival after endoscopic intervention in the clinical success group was notably longer than that in the clinical failure group (5.6 months vs. 1.5 months, p≤0.001). Conclusion Before endoscopic intervention, liver function, especially total bilirubin level, should be checked to achieve the best clinical outcome. Endoscopic intervention can be helpful to relieve jaundice in well selected patients with HCC. PMID:25048484

    Full Text Available Upper cervical chordoma (UCC is rare condition and poses unique challenges to surgeons. Even though transoral approach is commonly employed, a minimally invasive technique has not been established. We report a 44-year old Malay lady who presented with a 1 month history of insidious onset of progressive neck pain without neurological symptoms. She was diagnosed to have an axial (C2 chordoma. Intralesional resection of the tumour was performed transorally using the Destandau endoscopic system (Storz, Germany. Satisfactory intralesional excision of the tumour was achieved. She had a posterior fixation of C1-C4 prior to that. Her symptoms improved postoperatively and there were no complications noted. She underwent adjuvant radiotherapy to minimize local recurrence. Endoscopic excision of UCC via the transoral approach is a safe option as it provides an excellent magnified view and ease of resection while minimizing the operative morbidity.

    Gastroparesis is a condition characterized by delayed gastric emptying, and a constellation of symptoms, including nausea, vomiting, early satiety, and bloating. Although current surgical options such as pyloroplasty have been shown to be effective, an endoscopic submucosal myotomy technique may be applied to divide the pyloric sphincter without surgical access. Such endoscopic technique may provide the benefits of a natural orifice procedure, and improve gastric emptying in gastroparetic patients. Per-oral pyloromyotomy (POP) was performed in seven female patients aged 33-65 years (mean 51 years). All patients had a pre-operative work-up that included upper endoscopy, and a gastric emptying study. A pH study, and esophageal manometry were also performed when a concomitant fundoplication was considered. POP was technically successful in all seven cases. There were no immediate procedural complications. Perioperative, complications included: one patient with an upper GI bleed 2 weeks post-procedure, necessitating transfusions, and endoscopic clipping of a pyloric channel ulcer; one patient who experienced difficulty swallowing post operatively, delaying discharge by 1 day; and one patient who developed a hospital-acquired pneumonia, delaying discharge by several days. Six of the seven patients experienced significant symptomatic improvement following the procedure. Three month follow-up nuclear medicine solid-phase gastric emptying studies are currently available for 5 of the 7 patients. Normal gastric emptying at 4 h was noted in four of five patients (80 %). One patient did not respond to endoscopic management subsequently underwent an uneventful laparoscopic pyloroplasty, which also failed to significantly improve her symptoms. POP is a technically safe and feasible endoscopic procedure. Early follow-up suggests promising symptomatic improvement as well as objective improvement in gastric emptying. Additional clinical experience is required to establish the role

    Lumbar degenerative spondylolisthesis is a common entity and occurs mainly in elderly patients. The trend in surgery has been to offer decompression with instrumented fusion based on patient-based outcome data and the inherent instability of the condition. Transforaminal endoscopic discectomy and foraminotomy is an ultra-minimally invasive outpatient surgical option available to patients that does not require general anesthesia and does not involve the same amount of destabilizing facet joint removal as a traditional laminectomy and medial facetectomy. The purpose of this study was to assess the benefit of tranforaminal endoscopic discectomy and foraminotomy in patients with lumbar 4-5 (L4-L5) and lumbar 5-sacral 1 (L5-S1) spondylolisthesis and lumbar radiculopathy. After Institutional Review Board Approval, charts from 21 consecutive patients with L4-L5 or L5-S1 spondylolisthesis and complaints of lower back and radicular pain who underwent endoscopic procedures between 2007 and 2012 were reviewed. The average pain relief one year postoperatively was reported to be 71.9%, good results as defined by MacNab. The average pre-operative VAS score was 8.48, indicated in our questionnaire as severe and constant pain. The average one year postoperative VAS score was 2.30, indicated in our questionnaire as mild and intermittent pain. This is a retrospective study and only offers one year follow-up data for patients with spondylolisthesis undergoing endoscopic spine surgery for treatment of lumbar radiculopathy. Endoscopic discectomy is a safe and effective alternative to open back surgery. The one year follow-up data presented here appears to indicate that an ultra-minimally invasive approach to the treatment of lumbar radiculopathy in the setting of spondylolisthesis that has a low complication rate, avoids general anesthesia, and is outpatient might be worth studying in a prospective, longer term way.

    2017-01-01

    Full Text Available Introduction: Lumbar disc prolapse is most common between 30 and 50 years of age and is associated with severe disability and pain. It commonly occurs at L4/5 and L5/S1. Transforaminal endoscopic discectomy is an emerging technique for treatment of degenerative disc disease. Literature has shown clinical outcomes, comparable to classical open and micro lumbar discectomy. Central disc herniations in lumbar spine pose technical challenge for transforaminal endoscopic decompression due to its location. Existing techniques to access central herniations and ventral epidural space have trajectory related challenges due to the proximity of the retroperitoneal space and abdominal organs and technically difficult for the less experienced surgeon. Materials and Methods: Thirty patients – 19 males and 11 females – with central, multifocal, central-paracentral disc herniations in the lumbar spine operated in 2015 and 2016 were considered in this study. All patients underwent selective endoscopic discectomy under monitored care anesthesia and local anesthesia with modification of the classical technique, medialization of annulotomy, undercutting the nonarticular part of superior articular process (foraminotomy and use of articulating and long jaw instruments either alone or in combination. Results: In all the thirty patients, we were able to achieve adequate decompression with neurological recovery. All patients improved in their neurological status. Postoperatively, visual analog scale dropped from 7.8 to 1.8 and ODI dropped from 73.46% to 32. 90% of the patients reported excellent and good results. One patient had recurrent herniation and was treated with transforaminal surgery. One patient had persistent back pain and reported poor outcome. Three patients underwent medial branch block for facet joint pain followed by medial branch rhizotomy and reported excellent and good results. Conclusion: Transforaminal endoscopic spine surgery with modifications

    OBJECTIVE Recent studies have proposed the superior eyelid endoscopic transorbital approach as a new minimally invasive route to access orbital lesions, mostly in otolaryngology and maxillofacial surgeries. The authors undertook this anatomical study in order to contribute a neurosurgical perspective, exploring the anterior and middle cranial fossa areas through this purely endoscopic transorbital trajectory. METHODS Anatomical dissections were performed in 10 human cadaveric heads (20 sides) using 0° and 30° endoscopes. A step-by-step description of the superior eyelid transorbital endoscopic route and surgically oriented classification are provided. RESULTS The authors' cadaveric prosection of this approach defined 3 modular routes that could be combined. Two corridors using bone removal lateral to the superior and inferior orbital fissures exposed the middle and anterior cranial fossa (lateral orbital corridors to the anterior and middle cranial base) to unveil the temporal pole region, lateral wall of the cavernous sinus, middle cranial fossa floor, and frontobasal area (i.e., orbital and recti gyri of the frontal lobe). Combined, these 2 corridors exposed the lateral aspect of the lesser sphenoid wing with the Sylvian region (combined lateral orbital corridor to the anterior and middle cranial fossa, with lesser sphenoid wing removal). The medial corridor, with extension of bone removal medially to the superior and inferior orbital fissure, afforded exposure of the opticocarotid area (medial orbital corridor to the opticocarotid area). CONCLUSIONS Along with its minimally invasive nature, the superior eyelid transorbital approach allows good visualization and manipulation of anatomical structures mainly located in the anterior and middle cranial fossae (i.e., lateral to the superior and inferior orbital fissures). The visualization and management of the opticocarotid region medial to the superior orbital fissure are more complex. Further studies are needed

    Background: Since first reported in 1996, endoscopic minimally invasive surgery of the cervical region has been shown to be safe and effective in the treatment of benign thyroid and parathyroid disease. The endoscopic transaxillary technique uses a remote lateral approach to the thyroid gland. Because of the perceived difficulty in accessing the contralateral anatomy of the thyroid gland, this technique has typically been reserved for patients with unilateral disease. Objectives: The present study examines the safety and feasibility of the transaxillary technique in dissecting and assessment of both thyroid lobes in performing near total thyroidectomy. Methods: Prior to this study we successfully performed endoscopic transaxillary thyroid lobectomy in 32 patients between August 2003 and August 2005. Technical feasibility in performing total thyroidectomy using this approach was accomplished first utilizing a porcine model followed by three human cadaver models prior to proceeding to human surgery. After IRB approval three female patients with histories of enlarging multinodular goiter were selected to undergo endoscopic near total thyroidectomy. Results: The average operative time for all models was 142 minutes (range 57–327 min). The three patients in this study had clinically enlarging multinodular goiters with an average size of 4 cm. The contralateral recurrent laryngeal nerve and parathyroid glands were identified in all cases. There was no post-operative bleeding, hoarseness or subcutaneous emphysema. Conclusion: Endoscopic transaxillary near total thyroidectomy is feasible and can be performed safely in human patients with bilateral thyroid disease. PMID:16882421

    Conventional endoscopic resection techniques such as endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) are powerful tools for the treatment of gastrointestinal (GI) neoplasms. However, those techniques are limited to the superficial layers of the GI wall (mucosa and submucosa). Lesions without lifting sign (usually arising from deeper layers) or lesions in difficult anatomic positions (appendix, diverticulum) are difficult - if not impossible - to resect using conventional techniques, due to the increased risk of complications. For larger lesions (>2 cm), ESD appears to be superior to the conventional techniques because of the en bloc resection, but the procedure is technically challenging, time consuming, and associated with complications even in experienced hands. Since the development of the over-the-scope clips (OTSC), complications like bleeding or perforation can be endoscopically better managed. In recent years, different endoscopic full-thickness resection techniques came to the focus of interventional endoscopy. Since September 2014, the full-thickness resection device (FTRD) has the CE marking in Europe for full-thickness resection in the lower GI tract. Technically the device is based on the OTSC system and combines OTSC application and snare polypectomy in one step. This study shows all full-thickness resection techniques currently available, but clearly focuses on the experience with the FTRD in the lower GI tract.

    Full Text Available INTRODUCTION: Diverticular disease of the colon is a very common condition, present in most of the elderly population. However, the occurrence of rectal diverticula is extremely unusual. It is typically an incidental finding at colonoscopy. OBJECTIVE: Describe epidemiological, clinical, surgical and endoscopic characteristics of a case series of rectal diverticula in Brazil. METHODS: Four patients with rectal diverticula were analyzed in terms of symptomatology, associated conditions and colonoscopy findings. Endoscopic findings were discussed individually. RESULTS: The prevalence of rectal diverticula at our endoscopy unit was 0.15% of all colonoscopies, affecting 0.74% of patients with colonic diverticulosis. The endoscopic analysis showed the diverticulum ostium with mean size of 2.3 cm, depth of 2.8 cm and anal margin distance of 6.8 cm. Colonoscopy also demonstrated simple rectal diverticulum in all patients. Diverticula were located in the anterior, right lateral and posterior walls of the rectum. One patient developed diverticulitis as complication and underwent to diverticulectomy. CONCLUSIONS: Rectal diverticulum is an incidental finding at colonoscopy and associated with diverticulosis. Its rarity and specific colonoscopic characteristics make it a unique entity. Asymptomatic in most cases, it rarely needs intervention. Surgery is reserved for complicated cases.INTRODUÇÃO: Diverticulose é uma condição muito comum, presente em grande parte da população idosa. Divertículo retal, entretanto, é condição rara.

    2011-04-01

    Full Text Available Pancreatic cancer is devastating due to its poor prognosis. Patients require a multidisciplinary approach to guide available options, mostly palliative because of advanced disease at presentation. Palliation including relief of biliary obstruction, gastric outlet obstruction, and cancer-related pain has become the focus in patients whose cancer is determined to be unresectable. Endoscopic stenting for biliary obstruction is an option for drainage to avoid the complications including jaundice, pruritus, infection, liver dysfunction and eventually failure. Enteral stents can relieve gastric obstruction and allow patients to resume oral intake. Pain is difficult to treat in cancer patients and endoscopic procedures such as pancreatic stenting and celiac plexus neurolysis can provide relief. The objective of endoscopic palliation is to primarily address symptoms as well improve quality of life.

    Endoscopic ultrasound has become an invaluable tool in the investigation of patients with suspected pancreatobiliary disease. We set out to determine whether a "direct-to-test" endoscopic ultrasound procedure could be offered to selected patients with suspected choledocholithiasis. We included patients referred to our general gastroenterology service with clinical history, symptomatology and/or laboratory results compatible with choledocholithiais. Almost all patients had already had a transabdominal ultrasound performed at the request of their general practitioner. All patients underwent direct-to-test day-case endoscopic ultrasound under conscious sedation. Procedures were performed by a single practitioner using an oblique-viewing radial echoendoscope. The diagnostic yield and frequencies of discharge, onward referral and follow-up were determined. Overall diagnostic yield of direct-to-test endoscopic ultrasound was 61%. The most common diagnoses were cholelithiasis (18%) and choledocholithiasis (11%); one periampullary cancer was also detected. A definitive outcome (discharge or referral for a therapeutic procedure) occurred in 14 of 28 patients (50%). The remaining 14 patients underwent further out-patient evaluation. Eventual diagnoses in this group included autoimmune hepatitis, primary biliary cirrhosis and drug-induced hepatitis. For patients with suspected biliary disease, direct-to-test endoscopic ultrasound has a high diagnostic yield, and may be an appropriate mode of investigation. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Previous studies have compared the outcomes after open and endoscopic excision of an os trigonum in patients of mixed professions. No studies have compared the differences in outcomes between the 2 procedures in elite ballet dancers. From October 2005 to February 2010, 35 professional ballet dancers underwent excision of a symptomatic os trigonum of the ankle after a failed period of nonoperative treatment. Of the 35 patients, 13 (37.1%) underwent endoscopic excision and 22 (62.9%) open excision. We compared the outcomes, complications, and time to return to dancing. The open excision group experienced a significantly greater incidence of flexor hallucis longus tendon decompression compared with the endoscopic group. The endoscopic release group returned to full dance earlier at a mean of 9.8 (range 6.5 to 16.1) weeks and those undergoing open excision returned to full dance at a mean of 14.9 (range 9 to 20) weeks (p = .001). No major complications developed in either group, such as deep infection or nerve or vessel injury. We have concluded that both techniques are safe and effective in the treatment of symptomatic os trigonum in professional ballet dancers. Endoscopic excision of the os trigonum offers a more rapid return to full dance compared with open excision. Copyright © 2016 American College of Foot and Ankle Surgeons. Published by Elsevier Inc.

    2013-01-01

    Full Text Available Background: Sinusitis with orbital complication is a potentially fatal disease that has been known since the days of Hippocrates. Primary sinus infection is the most common cause of orbital cellulitis. It is an emergency that threatens not only vision but also life from complications such as meningitis, cavernous sinus thrombosis, and brain abscess. Surgical intervention is mandatory whenever antibiotic treatment fails. There are two surgical options for the drainage, an external approach via a Lynch incision and an intranasal endoscopic procedure. Materials and Methods: Five patients with orbital cellulitis secondary to acute on chronic rhinosinusitis were included in the study from the period of 2010 - 2011. All five patients did not respond to medical management and hence underwent endoscopic sinus surgery with treatment of orbital pathology. At the end of the surgical procedure Mitomycin C in a concentration of 0.4mg/ml was applied with a cottonoid for a period of 4 minutes to prevent chance of adhesion formation. Results: In this series 3 females and 2 male patient with orbital cellulitis secondary to acute on chronic rhinosinusitis underwent endoscopic sinus surgery with treatment of orbital pathology. All 5 patients showed subjective and objective improvement within one week of endoscopic management. Conclusion: Though antibiotics have altered the course of sinusitis, its grave complications still persist in our environment. The excellent results and the absence of any major complications of endoscopic sinus surgery and drainage of abscess with application of Mitomycin C can be recommended as the preferred surgical technique.

    Post traumatic anterior abdominal wall hernia can be ignored in emergency settings. We here report the case of a 32-year-old patient with a BMI of 30 kg/m 2 , suffering from anterior abdominal wall hernia as a result of a road accident. This lesion wasn't detected during clinical examination. Abdominal tomodensitometry showed a defect of 8 cm in the anterior abdominal wall. The patient underwent surgery during which a musculoaponeurotic defect of 12 cm was detected. The repair was carried out using interrupted suture. The postoperative course was marked by a secondarily infected skin necrosis. The evolution was satisfactory after directed cicatrization. At 3 months postoperatively the patient was doing well with a healed wound and a strong abdominal wall.

    Lateral spreading tumours are superficial spreading neoplasms now increasingly diagnosed using chromoscopic colonoscopy. The clinicopathological features and safety of endoscopic mucosal resection for lateral spreading tumours (G-type "aggregate" and F-type "flat") has yet to be clarified in Western cohorts. Eighty two patients underwent magnification chromoscopic colonoscopy using the Olympus CF240Z by a single endoscopist. All patients had received a previous colonoscopy where an endoscopic diagnosis of lateral spreading tumour was made. All lesions were examined initially using indigo carmine chromoscopy to delineate contour followed by crystal violet for magnification crypt pattern analysis. A 20 MHz "mini probe" ultrasound was used if T2 disease was suspected. Following endoscopic mucosal resection, patients were followed up at 3, 6, 12, and 24 months using total colonoscopy. Eighty two lateral spreading tumours were diagnosed in 80 patients (32% (26/82) F-type and 68% (56/82) G-type). G-type lesions were larger than F-type (G-type mean 42 (SD 14) mm v F-type 24 (6.4) mm; plateral spreading tumours using endoscopic mucosal resection at two years of follow-up was 96% (56/58). Endoscopic mucosal resection for lateral spreading tumours, staged as T1, is a safe and effective treatment despite their large size. Endoscopic mucosal resection may be an alternative to surgery in selected patients.

    The aim of this study was to compare the efficacy, rebleeding rates, survival, and complications of endoscopic variceal ligation (EVL) with those of endoscopic variceal obliteration (EVO) in patients with acute type 1 gastroesophageal variceal (GOV1) bleeding. Data were collected retrospectively at a single center. A total of 84 patients were selected (20 patients underwent EVL; 64 patients underwent EVO) from February 2004 to September 2011. Their clinical characteristics, laboratory results, vital signs, Child-Pugh score, Model for End-stage Liver Disease (MELD) score, and overall mortality were evaluated. There were no significant differences in baseline characteristics between the two groups. The success rate in initial control of active bleeding was not significantly different between the EVL and EVO groups (18/20 EVL, or 90.0%, compared with 62/64 EVO, or 96.9%; p=0.239). The early rebleeding rate was also not significantly different between the groups (3/18 EVL, or 16.7% compared with 17/62 EVO, or 27.4%; p=0.422). The late rebleeding rate of the EVL group was lower than that of the EVO group (3/18 EVL, or 16.7%, compared with 26/59 EVO, or 44.1%; p=0.042). The time-to-rebleeding was 594 days for the EVL group and 326 days for the EVO group (p=0.054). In the multivariate analysis, portal vein thrombosis (PVT) was a significant risk factor for early rebleeding. Hepatocellular carcinoma (HCC) and previous history of bleeding were significant risk factors for very late rebleeding. In conclusion, EVL is better than EVO in reducing late rebleeding in acute GOV1 bleeding. HCC, PVT, and previous bleeding history were significant risk factors for rebleeding.

    Background/Aims Biliary stone disease is one of the most common conditions leading to hospitalization. In addition to endoscopic retrograde cholangiopancreatography (ERCP), endoscopic ultrasonography (EUS) and magnetic resonance cholangiopancreatography (MRCP) are required in diagnosing choledocholithiasis. This study aimed to compare the sensitivity and specificity of EUS and MRCP against ERCP in diagnosing choledocholithiasis. Methods This retrospective study was conducted after prospective collection of data involving 62 suspected choledocholithiasis patients who underwent ERCP from June 2013 to August 2014. Patients were divided into two groups. The first group (31 patients) underwent EUS and the second group (31 patients) underwent MRCP. Then, ERCP was performed in both groups. Sensitivity, specificity, and diagnostic accuracy of EUS and MRCP were determined by comparing them to ERCP, which is the gold standard. Results The male to female ratio was 3:2. The mean ages were 47.25 years in the first group and 52.9 years in the second group. Sensitivity, specificity, accuracy, positive predictive value, and negative predictive value for EUS were 96%, 57%, 87%, 88%, and 80% respectively, and for MRCP were 81%, 40%, 68%, 74%, and 50%, respectively. Conclusions EUS is a better diagnostic tool than MRCP for diagnosing choledocholithiasis. PMID:28241408

    Discectomy, corpectomy, and resection of isolated posterior wall fragments are technically demanding steps requiring maximum surgical precision during anterior reconstruction of the unstable thoracolumbar spine. This study investigates the feasibility of computer-aided guidance for these steps. It also analyzes the precision, advantages, and disadvantages of the procedure. Controlled clinical trial. 21 patients were included in the trial group; the control group consisted of 10 patients. Total time for surgery was noted. To assess surgical precision, decentralization of the cage was measured in postoperative X-rays. Additionally, parallel alignment of vertebral body endplates with the cage was evaluated in postoperative CT scans. Vertebral body fractures of the thoracolumbar spine addressed by disc-/corpectomy and subsequent cage interposition for anterior reconstruction were included. All surgical steps were performed under endoscopic assistance. In the trial group, disc- and corpectomy were performed under computer-aided guidance; in the control group, no computer navigation was utilized. In cases of initial neurological deficit after trauma, the patients underwent emergency laminectomy during the initial posterior stabilization procedure. During the second-stage anterior procedure, resection of the posterior wall fragment with the aid of computer-aided navigation was performed. Fractures were localized between Th9 and L1 in the trial group, and Th10 and L1 in the control group. Time for surgery was significantly shorter in the control group: 1.7 h ± 0.5, as opposed to 3.8 h ± 1.0 in the trial group (p Computer-aided guidance in anterior reconstruction of the thoracolumbar spine is a technically feasible option that may aid in the performance of disc- and corpectomy, as well as the resection of isolated posterior wall fragments in cases with initial neurological compromise. However, total time for surgery is significantly prolongated by this technique

    Purpose This study aims to evaluate the endoscopic morphological features of congenital posterior urethral obstructions in boys with refractory daytime urinary incontinence and/or nocturnal enuresis. Patients and Methods A total of 54 consecutive patients underwent endoscopy and were diagnosed with a posterior urethral valve (PUV) (types 1-4). PUV type 1 was classified as severe, moderate, or mild. A transurethral incision (TUI) was mainly performed for anterior wall lesions of the PUV. Voiding cystourethrography and pressure flow studies (PFS) were performed before and 3 to 4 months after TUI. Clinical symptoms were evaluated 6 months after TUI, and outcomes were assessed according to PFS waveform pattern groups (synergic pattern [SP] and dyssynergic pattern [DP]). Results All patients had PUV type 1 and/or 3 (i.e., n = 34 type 1, 7 type 3, and 13 types 1 and 3). There were severe (n = 1), moderate (n = 21), and mild (n = 25) cases of PUV type 1. According to PFS, SP and DP were present in 43 and 11 patients, respectively. TUI was effective in the SP group and symptoms improved in 77.4 and 69.3% of patients with daytime incontinence and nocturnal enuresis, respectively. Almost no effect was observed in the DP group. A significant decrease in the detrusor pressure was observed at maximum flow rate using PFS in the SP group. Conclusions PUV type 1 encompassed lesions with a spectrum of obstructions ranging from severe to mild, with mild types whose main obstructive lesion existed at the anterior wall of urethra occurring most frequently in boys with refractory daytime urinary incontinence and/or nocturnal enuresis.

    Esophageal carcinoma is frequently diagnosed at an advanced stage. Therefore for most patients either surgical or endoscopic palliation with or without radiochemotherapy may be taken into consideration. This retrospective study analyzes immediate and long term results of perendoscopic treatment in patients with unresectable esophageal cancer. Moreover a comparative analysis has been made with a group of patients who underwent palliation surgery. From 1982 to 1998 458 patients with esophageal cancer underwent palliation perendoscopic disobstructive treatment (427 patients), palliation surgery (29 patients) and dis-obstruction followed by perendoscopic gastrostomy (2 patients). Among patients treated by perendoscopic procedures, 18 underwent dilation, 53 dilation and radiotherapy, 236 stent implantation, respectively of the plastic (102) and self-expandable metallic (134) type. 120 patients underwent NdYAG laser treatment. The results for patients who underwent perendoscopic procedures are referred to as regards the first 30 days after treatment and on the long run in terms of grade of dysphagia according to Visick's scale. For the group of patients undergoing simple dilation we had an improvement (from Visick III-IV to I-II) in 33% of cases and in 54.7% when radiotherapy was added. Far better results were achieved in all groups undergoing stent implantation, with or without brachytherapy, and NdYAG laser treatment with or without previous chemical necrolysis (range 90.3-100%). Most frequent complications were obstruction and stent displacement. Mean survival was better for patients undergoing laser recanalisation (7.2 months) while among stents the metallic type has given better results than plastic ones both for survival (6.2 vs 5.9 months) and mortality (2.4 vs 4.9%). Comparison with the group undergoing palliation surgery has shown that mean survival is the same for patients undergoing jejunostomy or gastrostomy while it is significantly better for patients

    Different orbital and transcranial approaches are performed in order to manage orbital tumors, depending on the location and size of the lesion within the orbit. These approaches provide a satisfactory view of the superior and lateral aspects of the orbit and the optic canal but involve risks associated with their invasiveness because they require significant displacement of orbital structures. In addition, external approaches to intraconal lesions may also require deinsertion of extraocular muscles, with subsequent impact on extraocular mobility. Recently, minimally invasive techniques have been proposed as valid alternative to external approaches for selected orbital lesions. Among them, transnasal endoscopic approaches, "pure" or combined with external approaches, have been reported, especially for intraconal lesions located inferiorly and medially to the optic nerve. The avoidance of muscle detachment and the shortness of the surgical intraorbital trajectory makes endoscopic approach less invasive, thus minimizing tissue damage. Endoscopic surgery decreases the recovery time and improves the cosmetic outcome not requiring skin incisions. The purpose of this study is to review and discuss the current surgical techniques for orbital tumors removal, focusing on endoscopic approaches to the orbit and outlining the key anatomic principles to follow for safe tumor resection.

    Abductor tendon tears are an increasingly recognized clinical entity in patients with lateral thigh pain and weakness. These “rotator cuff tears of the hip” typically result from chronic, nontraumatic rupture of the anterior fibers of the gluteus medius. Although the abductor tendon typically tears from the osseous insertion, the case discussed here ruptured at the musculotendinous junction. This is the first report of this abductor tear subtype and its endoscopic repair. PMID:23875152

    Full Text Available Balloon dilatation of stricture is one of the new treatment methods among patients with gastric outlet obstruction (GOO. However, the prevalence and underlying etiologies of GOO in various populations are different. The goal of the present study was to determine the effectiveness of endoscopic balloon dilatation and factors that would affect its success rate patients with benign etiology for GOO. Forty-five patients with the symptoms of benign GOO were randomly selected. Gastric outlet was delineated using double channel videoendoscopy. The information of initial balloon dilation was collected from recorded files. Balloon dilatation was repeated during the mean follow up of 9.9 ± 5.8 months. The severity of gastric pain was measured immediately before balloon dilatation and one month after procedure and was rated on a 10 cm visual analogue scale. The mean age of patients was 43.7 ± 18.1 years and 86.7% of them were men. Furthermore, 71.1% were H pylori positive. Response rate to endoscopic balloon dilatation was 80% and 8 patients underwent surgical resection. Weight loss was more frequent in non-responding group. The pain severity was significantly reduced more in responding subjects. No meaningful relationships were found between the responses to balloon dilatation and positive H pylori and cigarette smoking. Endoscopic balloon dilation is safe and effective for most patients with benign gastric outlet obstruction and has favorable long-term outcome.

    The 1999 Ionising Radiation Regulations recommend that medical professionals using ionising radiation should aim to keep exposure as 'low as reasonably practicable'. Urologists regularly use fluoroscopy during endoscopic surgical procedures. In some institutions, this is delivered by a radiographer whereas in others, it is delivered by the urological surgeon. To determine if radiographer-delivered fluoroscopy can reduce the exposure to ionising radiation during urological procedures. An analysis of 395 consecutive patients, who underwent endoscopic urological procedures requiring fluoroscopy, was performed simultaneously across two institutions, over a 4 month period. 321 patients were matched and included in the analysis. Radiographer delivered fluoroscopy was associated with reduced ionising radiation exposure for retrograde pyelography procedures ED 0.09626 vs. 1.323 mSev, p= 0.0003, and endoscopic stone surgeries ED 0.3066 Vs. 0.5416 mSev, p=0.0039, but not for ureterorenoscopic stone surgeries 0.4880 vs. 0.2213 mSev, p=0.8292. Radiographer delivered fluoroscopy could reduce the patient's exposure to ionising radiation for some urological procedures.

    The present study reports the clinical results of excision of a symptomatic os trigonum using an endoscopic procedure in professional ballet dancers. The hypothesis was that posterior endoscopic excision of the os trigonum would be safe and effective in treating posterior ankle impingement syndrome related to the os trigonum. Twelve professional dancers underwent excision of a symptomatic os trigonum for PAIS using a posterior endoscopic technique after failure of conservative treatment. The patients were evaluated pre- and postoperatively according to the American Orthopaedic Foot and Ankle Society hindfoot scale score, the Tegner activity scale score, and the visual analog scale score. The surgical time, timing of a return to sports, patient satisfaction, and any complications related to the procedure were recorded. The average postoperative follow-up duration was 38.9 ± 20.6 (range 12 to 72) months.

    Full Text Available Gastric volvulus is a life threatening condition characterized by an abnormal rotation of the stomach around an axis. Although the first line treatment of this disorder is surgical, we report here a case of gastric volvulus that was endoscopically managed using a novel strategy. An 83-year-old female with a history of pancreatic cancer status postpylorus-preserving Whipple procedure presented with a cecal volvulus requiring right hemicolectomy. Postoperative imaging included a CT scan and upper GI series that showed a gastric volvulus with the antrum located above the diaphragm. An upper endoscopy was advanced through the pylorus into the duodenum and left in this position to keep the stomach under the diaphragm. A second pediatric endoscope was advanced alongside and used to complete percutaneous endoscopic gastrostomy (PEG placement for anterior gastropexy. The patient’s volvulus resolved and there were no complications. From our review of the literature, the dual endoscopic technique employed here has not been previously described. Patients who are poor surgical candidates or those who do not require emergent surgery can possibly benefit the most from similar minimally invasive endoscopic procedures as described here.

    Tearing of the anterior capsule of the shoulder is a rare but debilitating injury for throwing athletes. However, there is very little in the literature to guide its diagnosis and treatment. In this case series, we outline our experience with anterior capsular tears of the shoulder in professional baseball players. Five professional baseball players were diagnosed with midsubstance tears of their anterior capsule. A trial of rest and rehabilitation failed in all patients, and they eventually underwent surgery. These patients were retrospectively reviewed. The presenting symptoms and findings were documented, and outcomes were assessed by the player's ability to return to play. The mean age was 33.5 years (range, 31-37 years), and all patients presented with anterior shoulder pain and the inability to throw. No patient had an acute traumatic injury. Magnetic resonance imaging provided the correct diagnosis in 4 patients, and the diagnosis was made with diagnostic arthroscopy in the fifth. Three underwent arthroscopic repair, and 2 underwent open repair of the anterior capsule. Of the 5 players, 4 (80%) returned to their preinjury level by a mean of 13.3 months (range, 8-18 months). Anterior capsular tears can occur in older throwing athletes. Surgical repair, whether arthroscopic or open, can yield good results in most patients.

    Colonoscopy plays a critical role in colorectal cancer (CRC) screening and has been widely regarded as the gold standard. Cecal intubation rate (CIR) is one of the well-defined quality indicators used to assess colonoscopy. To assess the impact of new technologies on the quality of colonoscopy by assessing completion rates. This was a dual-center study at the 2 nd Department of Surgery at Jagiellonian University Medical College and at the Specialist Center "Medicina" in Krakow, Poland. The CIR and cecal intubation time (CIT) in three different eras of technological advancement were determined. The study enrolled 27 463 patients who underwent colonoscopy as part of a national CRC screening program. The patients were divided into three groups: group I - 3408 patients examined between 2000 and 2003 (optical endoscopes); group II - 10 405 patients examined between 2004 and 2008 (standard electronic endoscopes); and group III - 13 650 patients examined between 2009 and 2014 (modern endoscopes). There were statistically significant differences in the CIR between successive eras. The CIR in group I (2000-2003) was 69.75%, in group II (2004-2008) was 92.32%, and in group III (2009-2014) was 95.17%. The mean CIT was significantly reduced in group III. Our study shows that the technological innovation of novel endoscopy devices has a great influence on the effectiveness of the CRC screening program. The new era of endoscopic technological development has the potential to reduce examination-related patient discomfort, obviate the need for sedation and increase diagnostic yields.

    The natural history of degenerative disease after instrumented lumbar fusion can result in symptomatic radiculopathy at the adjacent segment. Here we describe our experience with transforaminal endoscopic decompression for the treatment of adjacent segment radiculopathy. A technique for the transforaminal endoscopic treatment of lumbar radiculopathy adjacent to instrumented lumbar fusions is presented. Prospectively, we followed a series of 9 consecutive patients operated on with lumbar radiculopathy above (5) or below (4) their instrumented fusion. Preoperative and postoperative clinical data with 2-year follow-up are presented. A consecutive series of 9 patients who underwent transforaminal endoscopic treatment for lumbar radiculopathy adjacent to an instrumented spinal fusion between 2012 and 2014 is presented. Three patients required revision to fusion at 2, 13, and 19 months postoperatively. The mean visual analogue scale score for radicular pain improved from an average pain score before surgery of 8.4 to 1.3 1 year after surgery and the mean visual analogue scale for back pain improved from an average pain score before surgery of 8.0 to 4.7 1 year after surgery (excluding the 1 patient with 2month postoperative failure). Transforaminal endoscopic surgical access to adjacent level disease pathology may be a unique approach to the treatment of adjacent segment disease because it allows for neural decompression of disc and foraminal pathology without requiring significant destabilizing bone removal. However, the 2-year failure rate presented here is 33%, which indicates that the benefit of this technique may ultimately be temporary. Copyright © 2016 Elsevier Inc. All rights reserved.

    Peroral endoscopic myotomy (POEM) is an endoscopic alternative to laparoscopic esophageal myotomy. It requires a demanding skill set that involves both advanced endoscopic skills and knowledge of surgical anatomy and complication management. Determine the learning curve for POEM. Prospective cohort study. Tertiary-care teaching hospital. The study involved the first 40 consecutive patients undergoing the POEM procedure under a prospective institutional review board protocol (research.gov #NCT01399476, 1056). Peroral endoscopic myotomy for esophageal motility disorders. Length of procedure (LOP) and technical errors (inadvertent mucosotomy). A total of 40 patients underwent POEM. The mean LOP was 126 ± 41 minutes. The mean myotomy length was 9 cm (range, 6-20 cm). The LOP per centimeter myotomy and variability decreased as our experience progressed. The means (± standard deviation) of the LOP per centimeter myotomy were as follows: first cohort, 16 ± 4 minutes; second, 17 ± 5 minutes; third, 13 ± 3 minutes; fourth, 15 ± 2 minutes; and fifth, 13 ± 4 minutes. The incidence of inadvertent mucosotomy also decreased with increasing experience, to 8, 6, 4, 0, and 1, respectively. These minor complications were repaired intraoperatively with clips. There were 7 patients with capnoperitonium and another with bilateral capnothoraces that were associated with hemodynamic instability but resolved by Veress needle decompression. Two patients required endoscopy in the early postoperative period: self-limited hematemesis in one and radiologic evidence of leakage at the mucosotomy site in another. Nonrandomized study. Mastery of operative technique in POEM is evidenced by a decrease in LOP, variability of minutes per centimeter of myotomy, and incidence of inadvertent mucosotomies and plateaus in about 20 cases for experienced endoscopists. The learning curve can be shortened with very close supervision and/or proctoring. Copyright © 2013 American Society for

    Chronic appendicitis may be detected in as many as 10% of patients with right lower quadrant pain. Although the appendiceal orifice is easily identified during colonoscopy, its lumen has not been investigated so far. To determine the feasibility of endoscopic appendix imaging to identify features of chronic appendicitis in patients with recurrent right lower quadrant pain. Prospective, proof-of-concept study. University-based tertiary referral hospital. Colonoscopy scheduled because of right lower quadrant pain. First, the appendix orifice was cannulated with a guidewire and a Jagtome. Next fluoroscopic imaging was performed by injection of contrast agent into the appendix orifice, and then a SpyGlass endoscope was inserted for imaging of the appendiceal mucosa and for biopsy. Patients were monitored 3 hours after investigation, with follow-up at 4 weeks. Cannulation rate. Thirteen patients were included. Endoscopic imaging of the appendix was successful in 9 of 13 patients (69%). In 10 patients, a guidewire was placed; in 7 patients, biopsy specimens were taken, revealing histological signs of inflammation in 5. In 4 patients, visible fecoliths were removed by flushing. All patients were discharged on the same day. No adverse events occurred. Three patients reported resolution of pain at follow-up. One patient with strictures at appendicoscopy underwent surgical appendectomy. Histology confirmed the findings of chronic appendicitis with fibrosis. Patient number limits power for analysis. Endoscopic imaging of the appendix is feasible, safe, and clinically useful in patients with suspected chronic appendicitis. Copyright © 2014 American Society for Gastrointestinal Endoscopy.

    The aim of the present study was to investigate the advantages and disadvantages of the diving endoscopic technique in pituitary adenoma surgery, and the application value in determining the extent of tumor resection. A total of 37 patients with pituitary adenoma initially underwent tumor resection under an endoscope-assisted microscope via standard trans-nasal-sphenoidal approach, and tumor cavity structure was observed by applying the diving endoscopic technique. Surgery was subsequently performed again under a microscope or endoscope. The diving endoscopic technique allowed surgeons to directly observe the structure inside a tumor cavity in high-definition. In the present study, 24 patients had pituitary macroadenomas or microadenomas that did not invade the cavernous sinus, and were considered to have undergone successful total resection. Among these patients, no tumor residues were observed through the diving endoscopic technique. Some white lichenoid or fibrous cord-like tissues in the tumor cavity were considered to be remnants of tumors. However, pathology confirmed that these were not tumor tissues. For tumors that invaded the cavernous sinus in 13 patients, observation could only be conducted under the angulation endoscope of the diving endoscope; i.e., the operation could not be conducted under an endoscope. The present study suggests that the diving endoscopic technique may be used to directly observe the resection extent of tumors within the tumor cavity, especially the structure of the tumor cavity inside the sella turcica. The present study also directly validates the reliability of pituitary adenoma resection under endoscope-assisted microscope. In addition, the diving endoscopic technique also allows the surgeon to observe the underwater environment within the sella turcica.

    Transanal endoscopic microsurgery (TEM) is currently the only one-port system in endoscopic surgery, which a direct endoluminal approach can lead to the target organ through a natural opening of human body. TEM has been applied in colorectal surgery for over 3 decades. Compared with radical surgery, TEM has the advantages, such as quicker recovery, shorter hospital stay and fewer complications. One perfect TEM surgical system, which mainly consists of three parts, namely peculiar rectoscope for surgery, special surgical instruments and imaging system, is the foundation of standardized development of TEM. Accurate preoperative evaluation and staging is the key for good outcomes in TEM technology. In addition to digital examination of rectum, rigid sigmoidoscopy(or rectoscopy) should be routinely performed to confirm the location of the lesion and record it in a "time-in-clock" form. For lesions with undetermined nature, biopsy should be performed. For patients with rectal tumor, pelvic MRI examination can be used on the basis of routine endorectal ultrasonography (ERUS). Endoluminal suture is the challenge for standardized development of TEM, especially for those with large intestinal wall defects. Professional training is required to master suture technique. In 2016, the consensus of experts on TEM technology was formulated by TEM Study Group of Colorectal Cancer Specialty Committee of Chinese Anticancer Association. The recommended surgical indications for TEM include (1)rectal adenoma; (2)early rectal cancer with good histopathological features; (3)extended resection of locally malignant polyps by colonoscopy; (4)other rectal tumors suitable for local resection; (5)benign stricture or anastomotic stricture of the rectum; (6)repair of anastomotic leakage after low anterior resection of rectum; (7)diagnosis of rectal hemorrhage; (8)biopsy of rectum and surrounding lesions; (9)repair of rectovaginal fistula or mucosal flap transposition of the internal mouth of anal

    The diagnosis and management of pediatric cerebrospinal fluid (CSF) leak and encephalocele are challenging. The current study aimed to identify patient characteristics, review operative techniques, and evaluate the efficacy and safety of endoscopic endonasal repair in a pediatric population. We retrospectively reviewed the records of pediatric patients who underwent transnasal endoscopic repair of CSF leak with or without a meningocele or an encephalocele at Beijing Tongren Hospital, Capital Medical University, between July 2003 and May 2014. All patients had preoperative radiological evaluations and underwent endoscopic endonasal repair of their skull base defects. Altogether, 23 children (mean age 7.0 years) underwent the procedures. Sixteen cases were congenital, and 7 patients had trauma history. The herniations or defects included meningoencephaloceles in 15 cases, meningoceles in 4 cases, and CSF leak in 4 cases (2 patients had bilateral leaks). The leak or herniation sites were ethmoid roof in 10 patients (one was bilateral), cribriform plate in 5, lateral to the foramen cecum in 3, posterior wall of the frontal sinus in 1, sphenoid sinus in 2, lateral recess of the sphenoid sinus in 1, and sella turcica base in 2. All subjects had favorable clinical outcomes without recurrence during a follow-up of 6-123 months (mean 61.1 months). The endoscopic endonasal approach was the preferred method for repairing CSF leaks with or without an encephalocele in pediatric patients. Compared to traditional operations, this endoscopic procedure is minimally invasive, efficient, and safe.

    Open converted cholecystectomy could occur in patients who planned for laparoscopic cholecystectomy after endoscopic removal of choledocholithiasis. To evaluate the risk factors associated with open converted cholecystectomy. The data for all patients who underwent cholecystectomy after endoscopic removal of choledocholithiasis were retrospectively reviewed. Factors predictive for conversion to open cholecystectomy were analyzed. The rate of open converted cholecystectomy was 15.7 %. In multivariate analysis, cholecystitis (OR 1.908, 95 % CI 1.390-6.388, p = 0.005), mechanical lithotripsy (OR 6.129, 95 % CI 1.867-20.123, p choledocholithiasis, endoscopic retrograde cholangiography-related factors predictive for open converted cholecystectomy are helpful in planning the appropriate timing of surgery.

    Outbreaks of transmission of infection related to endoscopy despite reported adherence to reprocessing guidelines warrant scrutiny of all potential contributing factors. Recent reports from ambulatory surgery centers indicated widespread significant occult damage within endoscope working channels, raising concerns regarding the potential detrimental impact of this damage on the adequacy of endoscope reprocessing. We inspected working channels of all 68 endoscopes at our academic institution using a novel flexible inspection endoscope. Inspections were recorded and videos reviewed by 3 investigators to evaluate and rate channel damage and/or debris. Working channel rinsates were obtained from all endoscopes, and adenosine triphosphate (ATP) bioluminescence was measured. Overall endoscope working channel damage was rated as minimal and/or mild and was consistent with expected wear and tear (median 1.59 on our 5-point scale). Our predominant findings included superficial scratches (98.5%) and scratches with adherent peel (76.5%). No channel perforations, stains, or burns were detected. The extent of damage was not predicted by endoscope age. Minor punctate debris was common, and a few small drops of fluid were noted in 42.6% of endoscopes after reprocessing and drying. The presence of residual fluid predicted higher ATP bioluminescence values. The presence of visualized working channel damage or debris was not associated with elevated ATP bioluminescence values. The flexible inspection endoscope enables high-resolution imaging of endoscope working channels and offers endoscopy units an additional modality for endoscope surveillance, potentially complementing bacterial cultures and ATP values. Our study, conducted in a busy academic endoscopy unit, indicated predominately mild damage to endoscope working channels, which did not correlate with elevated ATP values.

    We retrospectively reviewed our experience in performing endoscopic extraperitoneal radical prostatectomy (EERPE) and totally extraperitoneal (TEP) hernia repair in one procedure to evaluate its feasibility and safety. Based on our experience of 70 laparoscopic radical prostatectomies, a total of 60 patients underwent EERPE. Eight of these had 10 hernias repaired with Prolene mesh. The median total operating time for EERPE was 165 minutes. Mesh placement required an additional 15 minutes for a unilateral hernia and 25 minutes for bilateral hernias. The conversion rate and the reoperation rate were 0%. The median duration of vesical catheterization was 8.3 days. One patient required a blood transfusion. The most common minor complications, occurring in eight patients, were edema and hematoma of the penis. No wound infection occurred. The only major complication was a deep venous thrombosis in one patient. No additional complications developed in the hernioplasty group. We conclude that the extraperitoneal approach for radical prostatectomy allows concomitant inguinal hernia repair with a low morbidity rate and within an acceptable operating time.

    Malignant gastric outlet obstruction represents a terminal stage in pancreatic cancer. Between 5% and 25% of patients with pancreatic cancer ultimately experience malignant gastric outlet obstruction. The aim in palliating patients with malignant gastric outlet obstruction is to reestablish an oral intake by restoring gastrointestinal continuity. This ultimately improves their quality of life in the advanced stages of cancer. The main drawback to operative bypass is the high incidence of delayed gastric emptying, particularly in this group of patients with symptomatic obstruction. This study aimed to compare surgical gastrojejunostomy and endoscopic stenting in palliation of malignant gastric outlet obstruction, acknowledging the diversity and heterogeneity of patients with this presentation. This retrospective study investigated patients treated for malignant gastric outlet obstruction from December 1998 to November 2008 at Nepean Hospital, Sydney, Australia. Endoscopic duodenal stenting was performed under fluoroscopic guidance for placement of the stent. The operative patients underwent open surgical gastrojejunostomy. The outcomes assessed included time to diet, hospital length of stay (LOS), biliary drainage procedures, morbidity, and mortality. Of the 45 participants in this study, 26 underwent duodenal stenting and 19 had operative bypass. Comparing the stenting and operative patients, the median time to fluid intake was respectively 0 vs. 7 days (P < 0.001), and the time to intake of solids was 2 vs. 9 days (P = 0.004). The median total LOS was shorter in the stenting group (11 vs. 25 days; P < 0.001), as was the median postprocedure LOS (5 vs. 10 days; P = 0.07). Endoscopic stenting is preferable to operative gastrojejunostomy in terms of shorter LOS, faster return to fluids and solids, and reduced morbidity and in-hospital mortality for patients with a limited life span.

    Endoscopic resection of duodenal non-lifting adenomas and subepithelial tumors is challenging and harbors a significant risk of adverse events. We report on a novel technique for duodenal endoscopic full-thickness resection (EFTR) by using an over-the-scope device. Data of 4 consecutive patients who underwent duodenal EFTR were analyzed retrospectively. Main outcome measures were technical success, R0 resection, histologic confirmation of full-thickness resection, and adverse events. Resections were done with a novel, over-the-scope device (full-thickness resection device, FTRD). Four patients (median age 60 years) with non-lifting adenomas (2 patients) or subepithelial tumors (2 patients) underwent EFTR in the duodenum. All lesions could be resected successfully. Mean procedure time was 67.5 minutes (range 50-85 minutes). Minor bleeding was observed in 2 cases; blood transfusions were not required. There was no immediate or delayed perforation. Mean diameter of the resection specimen was 28.3 mm (range 22-40 mm). Histology confirmed complete (R0) full-thickness resection in 3 of 4 cases. To date, 2-month endoscopic follow-up has been obtained in 3 patients. In all cases, the over-the-scope clip was still in place and could be removed without adverse events; recurrences were not observed. EFTR in the duodenum with the FTRD is a promising technique that has the potential to spare surgical resections. Modifications of the device should be made to facilitate introduction by mouth. Prospective studies are needed to further evaluate efficacy and safety for duodenal resections. Copyright © 2015 American Society for Gastrointestinal Endoscopy. Published by Elsevier Inc.

    The purpose of this study is to determine the effectiveness of endoscopic diode laser therapy in patients presenting rectal bleeding due to chronic radiation proctitis (CRP). A retrospective analysis of CRP patients who underwent diode laser therapy in a single institution between 2010 and 2016 was carried out. The patients were treated by non-contact fibers without sedation in an outpatient setting. Fourteen patients (median age 77, range 73-87 years) diagnosed with CRP who had undergone high-dose radiotherapy for prostatic cancer and who presented with rectal bleeding were included. Six required blood transfusions. Antiplatelet (three patients) and anticoagulant (two patients) therapy was not suspended during the treatments. The patients underwent a median of two sessions; overall, a mean of 1684 J of laser energy per session was used. Bleeding was resolved in 10/14 (71%) patients, and other two patients showed improvement (93%). Only one patient, who did not complete the treatment, required blood transfusions after laser therapy; no complications were noted during or after the procedures. Study findings demonstrated that endoscopic non-contact diode laser treatment is safe and effective in CRP patients, even in those receiving antiplatelet and/or anticoagulant therapy.

    Objectives. Demonstration and analysis of possibilities of video-endoscopy in the surgical treatment of hypertensive hemorrhages Materials and methods. We analyzed the results of surgical treatment of 35 patients with hypertensive intracranial hematomas which were removed using endoscopic method. Twenty-eight patients had putamen, 3 thalamic, 3 cerebellar and 1 subcortical hematoma; the volume of hematomas ranged from 14 to 84 cm3. Results. Neurological lesions completely disappeared in 7 patients, 6 patients had moderate and 17 severe disability. Five (14%) patients died. Outcome of treatment was significantly (psurgery, localization of the hemorrhage, presence and degree of transverse brain dislocation, repeated hemorrhages. Risk factors for poor outcome were depressed consciousness, recurrent hemorrhages, the transverse dislocation >6 mm and deep intracranial hematoma. Conclusions. The efficacy of endoscopic aspiration of hematomas is comparable to open surgical interventions but less traumatic.

    Transclival endoscopic endonasal surgery (EES) has recently been used for the treatment of posterior fossa tumors. The optimal method of reconstruction of large clival defects following EES has not been established. A morphometric analysis of the posterior fossa was performed in patients who underwent transclival EES to compare those with observed postoperative anatomical changes (study group) to 50 normal individuals (anatomical control group) and 41 matched transclival cases with preserved posterior fossa anatomy (case-control group) using the same parameters. Given the absence of clival bone following transclival EES, the authors used the line between the anterior commissure and the basion as an equivalent to the clival plane to evaluate the location of the pons. Four parameters were studied and compared in the two populations: the pontine location/displacement, the maximum anteroposterior (AP) diameter of the pons, the maximum AP diameter of the fourth ventricle, and the cervicomedullary angle (CMA). All measurements were performed on midsagittal 3-month postoperative MR images in the study group. Among 103 posterior fossa tumors treated with transclival EES, 14 cases (13.6%) with postoperative posterior fossa anatomy changes were identified. The most significant change was anterior displacement of the pons (transclival pontine encephalocele) compared with the normal location in the anatomical control group (p 50% of the clivus) and dura. Nine (64.3%) of the 14 patients were overweight (body mass index [BMI] > 25 kg/m(2)). An association between BMI and the degree of pontine encephalocele was observed, but did not reach statistical significance. The use of a fat graft as part of the reconstruction technique following transclival EES with dural opening was the single significant factor that prevented pontine displacement (p = 0.02), associated with 91% lower odds of pontine encephalocele (OR = 0.09, 95% CI 0.01-0.77). The effect of fat graft reconstruction was

    Full Text Available Introduction. Considered as a rare event, gastric syphilis (GS is reported as an organic form of involvement. Low incidence of GS emphasizes the importance of histopathological analysis. Objective. We aim to characterize GS endoscopic aspects in an immunocompetent patient. Case Report. A 23-year-old man presented with epigastric pain associated with nausea, anorexia, generalized malaise and 11 kg weight loss that started 1 month prior to his clinical consultation. Physical examination was normal except for mild abdominal tenderness in epigastrium. Endoscopy observed diminished gastric expandability and diffuse mucosal lesions, from cardia to pylorus. Gastric mucosa was thickened, friable, with nodular aspect, and associated with ulcers lesions. Gastric biopsies were performed, and histopathological analysis resulted in dense inflammatory infiltration rich in plasmocytes. Syphilis serologies were positive for VDRL and Treponema pallidum reagents. Immunohistochemical tests were positive for Treponema pallidum and CD138. The patient was treated with penicillin, leading to resolution of his clinical complaints and endoscopic findings. Conclusion. Diagnosis suspicion of GS is important in view of its nonspecific presentation. Patients with gastric symptoms that mimic neoplastic disease should be investigated thoroughly based on the fact that clinical, endoscopic, and histological findings can easily be mistaken for lymphoma or plastic linitis.

    Achalasia is a motility disorder of the esophagus characterized by dysphagia, regurgitation of undigested food, chest pain, weight loss and respiratory symptoms. The most common form of achalasia is the idiopathic one. Diagnosis largely relies upon endoscopy, barium swallow study, and high resolution esophageal manometry (HRM). Barium swallow and manometry after treatment are also good predictors of success of treatment as it is the residue symptomatology. Short term improvement in the symptomatology of achalasia can be achieved with medical therapy with calcium channel blockers or endoscopic botulin toxin injection. Even though few patients can be cured with only one treatment and repeat procedure might be needed, long term relief from dysphagia can be obtained in about 90% of cases with either surgical interventions such as laparoscopic Heller myotomy or with endoscopic techniques such pneumatic dilatation or, more recently, with per-oral endoscopic myotomy. Age, sex, and manometric type by HRM are also predictors of responsiveness to treatment. Older patients, females and type II achalasia are better after treatment compared to younger patients, males and type III achalasia. Self-expandable metallic stents are an alternative in patients non responding to conventional therapies. PMID:26839644

    The traditional method of management of posterior epistaxis has been with anteroposterior nasal packing. Apart from the high failure rate of 26-50% reported in various series, nasal packing is associated with marked discomfort and several complications. In order to avoid nasal packing, we started doing endoscopic cauterization in cases of posterior epistaxis. A total of 23 patients with posterior epistaxis were subjected to nasal endoscopy with the intent to stop bleeding by cauterization of the bleeding vessel. Of these, in four cases unsuspected diagnosis was made. Of the remaining 19, in three patients, the bleeding point could not be localized accurately and these patients were managed by anteroposterior packing. The rest of the 16 patients were managed by endoscopic cauterization. In four patients, there was recurrence of bleeding within 24 h. In one of these, cauterization controlled the bleeding while in the rest nasal packing had to be resorted to. Thus, of the 23 patients of posterior epistaxis subjected to nasal endoscopy, we could avoid nasal packing in 17 (74%). To conclude, endoscopic nasal cauterization is recommended as the first line to treatment in all cases of posterior epistaxis. This will not only prevent the uncomfortable and potentially dangerous nasal packing but also help in finding the underlying pathology.

    Full Text Available Background. Although uncommon, giant submucosal colon lipomas merit attention as they are often presented with dramatic clinical features such as bleeding, acute bowel obstruction, perforation and sometimes may be mistaken for malignancy. There is a great debate in the literature as to how to treat them. Case report. A patient, 67-year old, was admitted to the Clinic due to a constipation over the last several months, increasing abdominal pain mainly localized in the left lower quadrant accompanied by nausea, vomiting and abdominal distension. Physical examination was unremarkable and the results of the detailed laboratory tests and carcinoembryonic antigen remained within normal limits. Colonoscopy revealed a large 10 cm long, and 4 to 5 cm in diameter, mobile lesion in his sigmoid colon. Conventional endoscopic ultrasound revealed 5 cm hyperechoic lesion of the colonic wall. Twenty MHz mini-probe examination showed that lesion was limited to the submucosa. Since polyp appeared too large for a single transaction, it was removed piecemeal. Once the largest portion of the polyp has been resected, it was relatively easy to place the opened snare loop around portions of the residual polyp. Endoscopic resection was carried out safely without complications. Histological examination revealed the common typical histological features of lipoma elsewhere. The patient remained stable and eventually discharged home. Four weeks later he suffered no recurrent symptoms. Conclusion. Colonic lipomas can be endoscopically removed safely eliminating unnecessary surgery.

    Full Text Available The presence of ulcer in early gastric cancer (EGC is important for the feasibility of endoscopic resection, only a few studies have examined the clinicopathological implications of endoscopic ulcer in EGC.To determine the role of endoscopic ulcer as a predictor of clinical behaviors in EGC.Data of 3,270 patients with EGC who underwent surgery between January 2005 and December 2012 were reviewed. Clinicopathological characteristics were analyzed in relation to the presence and stage of ulcer in EGC. Based on endoscopic findings, the stage of ulcer was categorized as active, healing, or scar. Logistic regression analysis was performed to analyze factors associated with lymph node metastasis (LNM.2,343 (71.7% patients had endoscopic findings of ulceration in EGC. Submucosal (SM invasion, LNM, lymphovascular invasion (LVI, perineural invasion, and undifferentiated-type histology were significantly higher in ulcerative than non-ulcerative EGC. Comparison across different stages of ulcer revealed that SM invasion, LNM, and LVI were significantly associated with the active stage, and that these features exhibited significant stage-based differences, being most common at the active stage, and least common at the scar stage. The presence of endoscopic ulcer and active status of the ulcer were identified as independent risk factors for LNM.Ulcerative EGC detected by endoscopy exhibited more aggressive behaviors than non-ulcerative EGC. Additionally, the endoscopic stage of ulcer may predict the clinicopathological behaviors of EGC. Therefore, the appearance of ulcers should be carefully evaluated to determine an adequate treatment strategy for EGC.

    Full Text Available Endoscopic treatment has generally been accepted in the management of bleeding esophageal varices. Both the control of acute variceal bleeding and elective variceal eradication to prevent recurrent bleeding can be achieved via endoscopic methods. In contrast to acute and elective treatment, the role of endoscopic therapy in asymptomatic patients who have never had variceal bleeding remains controversial because of the rather disappointing results obtained from prophylactic sclerotherapy. Most published randomized controlled trials showed that prophylactic sclerotherapy had no effect on survival. In some studies, neither survival rate nor bleeding risk was improved. In this article, the author champions the view that asymptomatic esophageal varices should be endoscopically treated.

    Conventional endoscopic resection techniques such as endoscopic mucosal resection or endoscopic submucosal dissection are powerful tools for treatment of gastrointestinal neoplasms. However, those techniques are restricted to superficial layers of the gastrointestinal wall. Endoscopic full-thickness resection (EFTR) is an evolving technique, which is just about to enter clinical routine. It is not only a powerful tool for diagnostic tissue acquisition but also has the potential to spare surgical therapy in selected patients. This review will give an overview about current EFTR techniques and devices.

    The aim of this study was to investigate the value of a single stage with combined tri-endoscopic (duodenoscopy, laparoscopy and choledochoscopy) approach for patients with concomitant cholecystolithiasis and choledocholithiasis. Fifty-three patients with combined gallbladder stones and common bile duct stones from February 2014 to April 2015 were randomized assigned to two groups: 29 patients underwent single-stage surgery with combined duodenoscope, laparoscope and choledochoscope (combined tri-endoscopic group), and 29 patients underwent endoscopic sphincterotomy to remove common bile duct stones followed by laparoscopic cholecystectomy several days later (control group). The success rate of complete stone removal, procedure-related complication, hospital stay and the cost of hospitalization were compared between the two groups. Altogether, 53 patients (29 patients in combined tri-endoscopic group and 24 patients in control group) successfully underwent the surgery and ERCP procedure. Three patients in the control group developed post-ERCP pancreatitis. One case of bile leaking and one case of residual stone were noted in the combined tri-endoscopic group. There were no significant differences between the two groups with regard to both complete stone removal [96.6 % (28/29) vs. 100 % (24/24)] and procedure-related complication rate [3.4 % (1/29) vs. 12.5 % (3/24)] (p > 0.05). No open surgery was required in either group. There were significant differences between the two groups with regard to hospital stay (6.72 ± 1.3 days vs. 10.91 ± 1.6 days, p choledocholithiasis was just as safe and successful as the control group. In addition, it resulted in a shorter hospital stay and less cost.

    Intestinal surgery is an important part of Crohn disease (CD) treatment in children. The aim of the present study was to compare the rate of endoscopic recurrence at the sixth month after ileocecal resection (ICR) in children with CD treated with azathioprine between patients who received prior antitumor necrosis factor alpha (anti-TNF-α) therapy and those who were not administered this therapy. Moreover, we tried to identify the potential risk factors for disease recurrence and describe the schedule of long-term follow-up after surgery. We prospectively collected data from pediatric patients with CD, who underwent ICR between October 2011 and June 2015 at our hospital and were treated with azathioprine monotherapy after ICR. We evaluated the endoscopic recurrence (Rutgeerts score) at the sixth month after ICR in all included patients. Among 21 included patients, 13 achieved endoscopic remission (Rutgeerts score factors associated with endoscopic recurrence rate at the sixth month. Prior anti-TNF-α therapy does not seem to be a strong risk factor for endoscopic recurrence within 6 months after ICR. Further studies on large sample of patients are needed to identify potential predictors of disease recurrence.

    Endoscopic full-thickness plication allows transmural suturing at the gastroesophageal junction to recreate the antireflux barrier. Multichannel intraluminal impedance monitoring (MII) can be used to detect nonacid or weakly acidic reflux, acidic swallows, and esophageal clearance time. This study used MII to evaluate the outcome of endoscopic full-thickness plication. In this study, 12 subsequent patients requiring maintenance proton pump inhibitor therapy underwent endoscopic full-thickness plication for treatment of gastroesophageal reflux disease. With patients off medication, MII was performed before and 6-months after endoscopic full-thickness plication. The total median number of reflux episodes was significantly reduced from 105 to 64 (p = 0.016). The median number of acid reflux episodes decreased from 73 to 43 (p = 0.016). Nonacid reflux episodes decreased from 23 to 21 (p = 0.306). The median bolus clearance time was 12 s before treatment and 11 s at 6 months (p = 0.798). The median acid exposure time was reduced from 6.8% to 3.4% (p = 0.008), and the DeMeester scores were reduced from 19 to 12 (p = 0.008). Endoscopic full-thickness plication significantly reduced total reflux episodes, acid reflux episodes, and total reflux exposure time. The DeMeester scores and total acid exposure time for the distal esophagus were significantly improved. No significant changes in nonacid reflux episodes and median bolus clearance time were encountered.

    The gold standard of treatment for esthesioneuroblastoma consists of en bloc craniofacial resection with postoperative therapy dictated by histology and tumor extent. Numerous studies have shown fully endoscopic approaches to provide comparable survival and recurrence rates with decreased patient morbidity. Here we report the first multi-institutional series assessing smell outcomes of patients who underwent unilateral endoscopic resection of esthesioneuroblastoma with preservation of the contralateral olfactory bulb. A multi-institutional retrospective review was performed identifying patients who underwent endoscopic unilateral resection of esthesioneuroblastoma with preservation of 1 olfactory bulb between 2003 and 2015. After completion of postoperative radiation, patients were administered the University of Pennsylvania Smell Identification Test (UPSIT) to assess olfactory function. Fourteen patients (7 males, 7 females) were identified and tested for posttreatment olfactory function. All 14 patients received postoperative radiotherapy and 4 patients received additional chemotherapy. Mean follow-up time was 51.7 months. There was no disease recurrence. Six patients (43%) were found to have residual smell function with 2 patients (14%) having normal or mildly reduced smell function. Here we report the first multi-institutional series demonstrating smell preservation after unilateral endoscopic resection of esthesioneuroblastoma. In carefully selected patients, this approach can yield comparable survival with decreased patient morbidity. © 2016 ARS-AAOA, LLC.

    Background: An intrauterine device is commonly used for contraception globally. Although intrauterine device placement is an effective and safe method of contraception, migration into the bladder with stone formation is a rare and serious complication. The management approaches for an intrauterine device embedded in the bladder include endoscopic procedures and open surgical removal. In this study, we report the case of a patient with recurrent urinary tract infection associated with intrauterine device migration and urolithiasis, who successfully underwent endoscopic treatment combined with laser fragmentation. Case Presentation: A 22-year-old woman presented to our hospital with a 1-month history of lower abdominal pain, hematuria, and pain on urination. Transvaginal ultrasound showed a hyperechoic lesion in the bladder. A plain abdominal radiograph showed the presence of a T-shaped intrauterine device with calculus formation in the pelvis. CT revealed a vesical stone fixed to the top of the bladder wall, and there was no vesicovaginal fistula formation. She had undergone intrauterine device insertion several years previously. Cystoscopy confirmed the diagnosis. She underwent endoscopic lithotripsy, and the intrauterine device was extracted from the bladder wall. Repair of the bladder wall and disappearance of symptoms were confirmed. Conclusion: Endoscopic treatment combined with laser fragmentation of stones surrounding a migrated intrauterine device should be considered as a minimally invasive approach, which can be performed safely.

    2007-01-01

    To present the experience of the Orthopedics Service PEMEX South Central Hospital in the management of anterior unidirectional shoulder instability with an arthroscopic technique consisting of capsular retensioning either combined with other anatomical repair procedures or alone. Thirty-one patients with anterior unidirectional shoulder instability operated-on between January 1999 and December 2005 were included. Fourteen patients underwent capsular retensioning and radiofrequency, and in 17 patients, capsular retensioning was combined with suture anchors. Patients with a history of relapsing glenohumeral dislocations and subluxations, with anterior instability with or without associated Bankart lesions were selected; all of them were young. The results were assessed considering basically the occurrence of instability during the postoperative follow-up. No cases of recurring instability occurred. Two cases had neuroma and one experienced irritation of the suture site. Six patients had residual limitation of combined lateral rotation and abduction movements, of a mean of 10 degrees compared with the healthy contralateral side. The most frequent incident was the leak of solutions to the soft tissues. Capsular retensioning, whether combined or not with other anatomical repair techniques, has proven to result in a highly satisfactory rate of glenohumeral stabilization in cases of anterior unidirectional instabilities. The arthroscopic approach offers the well-known advantages of causing less damage to the soft tissues, and a shorter time to starting rehabilitation therapy and exercises.

  11. ENDOSCOPIC ASSISTED APPROACH TOWARDS FRONTONASAL DERMOID CYST/CYST SINUS

    Full Text Available Nasofrontal masses belong to the group of congenital midface anomalies (CMFA in paediatric age group. The usual list of differential diagnosis for such masses can be narrowed to Frontonasal de rmoid, epidermoid, nasal encephalocele and nasal gliomas. Frontonasal dermoid with patent dermal sinus tract is a rare craniofacial anomaly resulting from the failure of normal embryonic development. Most of patients present in infancy or early childhood. CT, MRI and sinogram together are usually required for definitive diagnosis. Knowledge of embryonic development of nose & anterior skull base is important in understanding the pathologies of Frontonasal masses. Endoscopic ‘key - hole’ approach to these lesio ns via small incision allows better visualization & ensures complete removal.

    Summary Background Internal snapping hip is a common clinical condition, characterized by an audible or palpable snap of the medial compartment of the hip. In most cases it is asymptomatic, while in a few patients, mostly in athletes who participate in activities requiring extremes of hip range of motion, the snap may become painful (internal snapping hip syndrome - ISHS). Materials and methods This is a review of current literature, focused on the pathogenesis, diagnosis and treatment of ISHS. Conclusion The pathogenesis of ISHS is multifactorial, and it is traditionally believed to be caused by the tendon snapping over the anterior femoral head or the iliopectineal ridge. Most cases of ISHS resolve with conservative treatment, which includes avoidance of aggravating activities, stretching, and NSAIDs. In recalcitrant cases, surgery may be indicated. Better results have been reported with endoscopic iliopsoas tendon release compared with open techniques, which may be related to the treatment of concomitant intra-articular pathologies. Furthermore, endoscopic treatment showed fewer complications, decreased failure rate and postop erative pain. It is important to remember that in most cases, a multiple iliopsoas tendon may exist, and that the incomplete release of the iliopsoas tendon can be a reason for refractory pain and poor results. Then, even if of not clinical relevance at long term follow-up, patients should be told about the inevitable loss of flexion strength after iliopsoas tenotomy. Level of evidence II. PMID:28066743

    Findings have shown endoscopic necrosectomy to be beneficial for patients with symptomatic pancreatic necrosis accessible for an endoscopic approach. The available studies show that endoscopic necrosectomy requires a multitude of subsequent procedures including repeat irrigation for removal of the necrotic material. This study aimed to investigate the need for additional irrigation in patients with necrotizing pancreatitis treated by endoscopic necrosectomy. The study enrolled 35 consecutive patients (27 men) with a median age of 59 years who had pancreatic necrosis treated with endoscopic necrosectomy. Endoscopic ultrasound-guided internal drainage and consecutive endoscopic necrosectomy was combined with interval multistenting of the cavity. Neither endoscopic nor external irrigation was part of the procedure. An average of 6.2 endoscopy sessions per patient were needed for access, necrosectomy, and stent management. The in-hospital mortality rate was 6% (2/35), including one procedure-related death resulting from postinterventional aspiration. The immediate morbidity rate was 9% (3/35). It was possible to achieve clinical remission for all the surviving patients with no additional surgery needed for management of the necroses. The median follow-up period was 23 months. Neither endoscopic nor external flushing is needed for successful endoscopic treatment of symptomatic necroses. Even without irrigation, the outcome for patients treated with endoscopic necrosectomy is comparable to that described in the published data.

    Having one hand occupied with the endoscope is the major disadvantage for the surgeon when it comes to functional endoscopic sinus surgery (FESS). Only the other hand is free to use the surgical instruments. Tiredness or frequent instrument changes can thus lead to shaky endoscopic images. We collected the pose data (position and orientation) of the rigid 0° endoscope and all the instruments used in 16 FESS procedures with manual endoscope guidance as well as robot-assisted endoscope guidance. In combination with the DICOM CT data, we tracked the endoscope poses and workspaces using self-developed tracking markers. All surgeries were performed once with the robot and once with the surgeon holding the endoscope. Looking at the durations required, we observed a decrease in the operating time because one surgeon doing all the procedures and so a learning curve occurred what we expected. The visual inspection of the specimens showed no damages to any of the structures outside the paranasal sinuses. Robot-assisted endoscope guidance in sinus surgery is possible. Further CT data, however, are desirable for the surgical analysis of a tracker-based navigation within the anatomic borders. Our marker-based tracking of the endoscope as well as the instruments makes an automated endoscope guidance feasible. On the subjective side, we see that RASS brings a relief for the surgeon.

    1984-01-01

    During a 36-month period, 89 patients have undergone percutaneous endoscopic gastrostomy without mortality. Of these patients, 25 (13 infants and children, 12 adults) had prior abdominal procedures that increased their risk for the endoscopic procedure. With two exceptions, all gastrostomies were performed utilizing local anesthesia. There was one major complication, a gastrocolic fistula, which was successfully managed by repeating the endoscopic gastrostomy procedure at a location more cephalad in the stomach. Twenty-two of the gastrostomies were placed for feeding purposes and all of these patients were able to leave the hospital with alimentation accomplished via the tube. Three of the endoscopically placed gastrostomies were for gastrointestinal tract decompression. A total of 255 patient months have been accumulated in these patients with the endoscopically placed gastrostomy in situ. The technique can be safely performed in patients with prior abdominal surgery and in the majority of cases is the technique of choice for establishing a tube gastrostomy. PMID:6428334

  8. The Use of Endoscopic Ultrasonography and Other Imaging Modalities in the Preoperative Staging of Rectal Villous Tumours: A Case of Overstaging by Magnetic Resonance Imaging

    Directory of Open Access Journals (Sweden)

    Michelle Buresi

    2009-01-01

    Full Text Available A case of a 60-year-old man with recurrent rectal villous adenoma is described. Preoperative staging with endoscopic ultrasound (EUS and magnetic resonance imaging (MRI revealed very discordant results. EUS showed a tumour present in the mucosa with no submucosal invasion, while MRI revealed invasion of the muscularis propria consistent with an invasive stage T2 carcinoma. Based on the MRI findings, the patient underwent a low anterior resection of the tumour. The surgical pathology specimen revealed a villous adenoma with low-grade dysplasia but no carcinoma and no extension into the muscularis propria. The present case highlights the uncertainty that currently exists as to which imaging modality provides the greatest accuracy in the staging of rectal cancer and in guiding the type of surgical procedure performed. Two recent meta-analyses and a systematic review of the literature point to EUS as the imaging modality of choice for determining muscularis propria and perirectal tissue invasion, as well as nodal involvement.

    2006-01-01

    The endoscopic approach can be used successfully for the treatment of benign tumors such as fibroosseous and vascular lesions, pleomorphic adenoma, glioma, meningioma, and schwannoma. Thirty-three patients diagnosed with benign tumors of the nasal cavity and paranasal sinuses and treated using an endoscopic approach were reviewed retrospectively. The endoscopic approach was simple in 28 cases and associated with an external approach in 5 cases (because of an intracranial extension of the tumor in four patients and its location at the level of the anterior wall of the frontal sinus in the last case). The resection of the lesions was complete in 32 patients and subtotal in one case. The mean follow-up was 28 months and only two recurrences (6%) were observed in the juvenile angiofibroma group and in the case of the fibrous dysplasia associated to aneurysmal bone cyst, respectively, 20 and 24 months postoperatively. In selected cases, endoscopic surgery can be considered an effective treatment for the resection of benign tumors involving the sinonasal tract.

    Entrapment of the temporal horn, known as isolated lateral ventricle (ILV), is a rare type of noncommunicating focal hydrocephalus, and standard treatment has not been established. We report 2 cases of endoscopic surgery for ILV and highlight the anatomic surgical nuances to avoid associated surgical risks. The first patient presented with recurrent ILV following initial shunt placement for ILV, owing to shunt malfunction. In the second patient, ILV recurred secondary to choroid plexus inflammation caused by cryptococcal infection. Endoscopic temporal ventriculocisternostomy was effective in both cases. However, in the second case, the choroidal fissure was fenestrated, which led to cerebral infarction in the territory of the choroidal artery zone, attributed to damage of the branches of the choroidal segment of the anterior choroidal artery. Although endoscopic temporal ventriculocisternostomy is considered a safe and less invasive procedure for treatment of symptomatic ILV, the technique is still associated with risks. To avoid complications, it is necessary to be familiar with the anatomy of the choroidal arteries and the pertinent endoscopic intraventricular orientation. Additionally, sufficient experience is required before it can be recommended as the treatment of choice. Copyright © 2017 Elsevier Inc. All rights reserved.

    Endoscopic retrograde cholangiopancreatography (ERCP) is currently the treatment of choice for symptomatic choledocholithiasis in pregnant patients. We aimed to present our experience with pregnant patients who underwent nonradiation ERCP and to evaluate the safety and efficacy of a new technique. A retrospective analysis of nonradiation ERCP in 22 pregnant patients with symptomatic choledocholithiasis between January 2002 and December 2013 was performed. The bile aspiration technique with wire-guided sphincterotome was used to confirm selective biliary cannulation. Transpapillary pancreatic septotomy was performed in cases with difficult biliary cannulation (n = 3). After endoscopic biliary sphincterotomy, endoscopic papillary balloon dilation was performed with a 6- or 8-mm dilation balloon in all patients to reduce the risk of recurrent cholangitis because of residual or additional stones. Stones were extracted by balloon sweeping after dilation. All patients were followed for 6 months after the ERCP procedure. Biliary cannulation was achieved in all patients. Endoscopic papillary balloon dilation was performed with a 6-mm balloon in 17 patients and an 8-mm balloon in five patients. The stones were extracted in 18 of the 22 patients by balloon sweeping, but no stones were extracted in the remaining four patients. There were two cases of mild post-ERCP pancreatitis. All patients delivered at term, and none experienced recurrence of choledocholithiasis and/or cholangitis during the 6-month follow-up. Endoscopic biliary sphincterotomy plus endoscopic papillary balloon dilation in nonradiation ERCP is a safe and effective treatment method for symptomatic choledocholithiasis during pregnancy.

    Endoscopic biliary stenting is well known as an optimal method of management of malignant hilar obstruction, but sometimes the result is not satisfactory, with early stent failure. Percutaneous transhepatic biliary drainage (PTBD) has a distinct advantage over endoscopic retrograde cholangiopancreatoscopy in that with ultrasound guidance one or more appropriate segments for drainage can be chosen. We evaluated the effectiveness of percutaneous transhepatic stenting as a rescue of early failure of endoscopic stenting. Ten patients (4 men, 6 women; age range, 52-78 years; mean age, 69 years) with inoperable biliary obstruction (2 patients with gall bladder cancer and hilar invasion, and 8 patients with Klatskin tumor) and with early endoscopic stent failure were included in our study. All of the patients underwent PTBD and percutaneous transhepatic biliary stenting. Metallic stents were placed in all patients for internal drainage. Percutaneous rescue stenting was successful in all the patients technically and clinically. Mean time for the development of biliary obstruction was 13.5 days after endoscopic stenting. The mean patency of the rescue stenting was 122 days. The mean survival time for percutaneous transhepatic rescue stenting was 226.3 days. In early failure of endoscopic biliary stenting, percutaneous transhepatic recanalization can be a possible solution.

    Full Text Available The objective of this study is to highlight the possibility of dysphagia induced by anterior cervical osteophytes. When not diagnosed early this condition may be responsible for complications such as severe dysphagia and potential lung aspiration, especially in elderly patients. Analysis of a case report of a 72-year old woman who presented cervical pain and progressive dysphagia. Imaging studies have shown anterior cervical osteophytosis and multilevel degenerative changes in the cervical spine. The patient underwent surgical excision of the cervical anterior osteophytes (C4, C5 and C6 and C5/C6 arthrodesis through anterior approach. The postoperative period was uneventful and symptoms resolved within 2 weeks. Early diagnosis and treatment led to complete resolution, avoiding late and serious complications associated with this pathology in the geriatric population, especially severe and progressive dysphagia and risk of pulmonary aspiration, and the consequent morbidity and mortality associated. A multidisciplinary approach is essential for the correct assessment of this condition

    Full Text Available A 46-year-old male patient was referred to our clinic with complaints of diplopia and esotropia in his right eye that developed after a car accident. The patient had right esotropia in primary position and abduction of the right eye was totally limited. Primary deviation was over 40 prism diopters at near and distance. The patient was diagnosed with sixth nerve palsy and 18 months after trauma, he underwent right medial rectus muscle recession. Ten months after the first operation, full-thickness tendon transposition of the superior and inferior rectus muscles (with Foster suture was performed. On the first postoperative day, slit-lamp examination revealed corneal edema, 3+ cells in the anterior chamber and an irregular pupil. According to these findings, the diagnosis was anterior segment ischemia. Treatment with 0.1/5 mL topical dexamethasone drops (16 times/day, cyclopentolate hydrochloride drops (3 times/day and 20 mg oral fluocortolone (3 times/day was initiated. After 1 week of treatment, corneal edema regressed and the anterior chamber was clean. Topical and systemic steroid treatment was gradually discontinued. At postoperative 1 month, the patient was orthophoric and there were no pathologic symptoms besides the irregular pupil. Anterior segment ischemia is one of the most serious complications of strabismus surgery. Despite the fact that in most cases the only remaining sequel is an irregular pupil, serious circulation deficits could lead to phthisis bulbi. Clinical properties of anterior segment ischemia should be well recognized and in especially risky cases, preventative measures should be taken.

    466 endoscopic polypectomies of the upper and lower gastrointestinal tract were analysed according to their curative value. In 254 removed polyps of the upper gastrointestinal tract the result of the histological examination was twice a proof of a carcinoma. One it had to be after-resected, once a carcinoid, five times bleeding polyps were removed. Four times prolapsing gastric polyps were removed in the bulbus duodeni. In these cases intermittent disturbances of the passage could be repaired. Thus the endoscopic polypectomy in the upper gastrointestinal tract was of therapeutic value in 4.3%. In the lower intestinal tract in 204 polypectomies 16 focal carcinomas or invasive carcinomas removed in the healthy tissue, 1 carcinoid and 98 bleeding adenomas were cut away. Thus the coloscopic polypectomy was connected with a therapeutic use in 56.3%. 81.8% of the polyps was tubular, papillary or villous adenomas. Taking into consideration the "adenoma-cancer-sequence", the coloscopic polypectomy must thus be regarded as a prophylactic and curative method, while in the polypectomy in the upper gastrointestinal tract the diagnostic value is in the first place.

    Many approaches to the anterior skull base have been reported. Frequently used are the pterional, the unilateral or bilateral frontobasal, the supraorbital and the frontolateral approach. Recently, endoscopic transnasal approaches have become more popular. The benefits of each approach has to be weighted against its complications and limitations. The aim of this study was to investigate if the anterior interhemispheric approach (AIA) could be a safe and effective alternative approach to tumorous and non-tumorous lesions of the anterior skull base. We screened the operative records of all patients with an anterior skull base lesion undergoing transcranial surgery. We have used the AIA in 61 patients. These were exclusively patients with either olfactory groove meningioma (OGM) (n = 43), ethmoidal dural arteriovenous fistula (dAVF) ( n = 6) or frontobasal fractures of the anterior midline with cerebrospinal fluid (CSF) leakage ( n = 12). Patient records were evaluated concerning accessibility of the lesion, realization of surgical aims (complete tumor removal, dAVF obliteration, closure of the dural tear), and approach related complications. The use of the AIA exclusively in OGMs, ethmoidal dAVFs and midline frontobasal fractures indicated that we considered lateralized frontobasal lesions not suitable to be treated successfully. If restricted to these three pathologies, the AIA is highly effective and safe. The surgical aim (complete tumor removal, complete dAVF occlusion, no rhinorrhea) was achieved in all patients. The complication rate was 11.5 % (wound infection (n = 2; 3.2 %), contusion of the genu of the corpus callosum, subdural hygroma, epileptic seizure, anosmia and asymptomatic bleed into the tumor cavity (n = 1 each). Only the contusion of the corpus callosum was directly related to the approach (1.6 %). Olfaction, if present before surgery, was preserved in all patients, except one (1.6 %). The AIA is an effective and a safe approach

    Same-day closure of bilateral tympanic membrane perforations is a quick and more comfortable procedure for the patients. However, conventional bilateral same-day tympanoplasty or myringoplasty has been rarely performed because of the theoretical risk of postoperative complications. To evaluate the advantages and outcomes of bilateral simultaneous endoscopic cartilage tympanoplasty in patients with bilateral tympanic membrane perforations. From February 2012 to March 2013, patients with bilateral dry tympanic membrane perforations who had some degree of hearing loss corresponding to the size and location of the perforation entered the study. There was no suspicion to disrupted ossicular chain, mastoid involvement or other middle or inner ear pathology. Endoscopic transcanal cartilage tympanoplasty was done using the underlay (medial) technique. The graft was harvested from cymba cartilage in just one ear with preservation of perichondrium in one side. A 1.5cm×1.5cm cartilage seemed to be enough for tympanoplasty in both sides. Nine patients (4 males and 5 females) with the mean age of 37.9 years underwent bilateral transcanal cartilage tympanoplasty in a same-day surgery. The mean duration of follow up was 15.8 months. There were detected no complications including hearing loss, otorrhea and wound complication with no retraction pocket or displaced graft during follow-up period. The grafts take rate was 94.44% (only one case of unilateral incomplete closure). The mean of air-bone gap overall improved from 13.88dB preoperatively to 9.16dB postoperatively (p<0.05). Bilateral endoscopic transcanal cartilage tympanoplasty can be considered as a safe minimally invasive procedure that can be performed in a same-day surgery. It reduces the costs and operation time and is practical with a low rate of postoperative complications. Copyright © 2017 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

    While the role of endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic sphincterotomy (EST) in the diagnosis and management of choledocholithiasis is well established, this study evaluates the usefulness of ERCP and EST patients with symptomatic cholecystolithiasis and suspected choledocholithiasis before undergoing laparoscopic cholecystectomy (LC), and the role of ERCP-EST in the management of complications resulting from LC. This paper reviews retrospectively our experience from 1992 to 1995. A total of 1221 LCs and 717 ERCPs were performed on 225 patients who underwent LC (230 ERCPs before and 27 after). The age range was 10-85 years (mean 43.5. The study group comprised 148 (66%) females and 77 males (34%). The overall success rate for ERCP was 92% (96% for diagnostic and 88% for therapeutic). Choledocholithiasis was found at preoperative ERCP in 45% cases. Prediction of cholecoledocholithiasis was accurate in 46%, based on abnormal liver chemistry, and 70% when based on a combination of abnormal liver tests and dilated main bile duct (>7 mm) by ultrasound. In 40 cases of acute biliary pancreatitis, choledocholithiasis was found at ERCP in eight cases (20%). In the post LC-group, all eight cases with residual stones and seven of eight cases with bile leaks were successfully treated endoscopically. There were four cases with major duct injuries that required surgical management. The complications related to ERCP-EST included two cases of bleeding post-EST (one was controlled with injection therapy and the second one was managed surgically) and three cases of mild pancreatitis. ERCP and EST are effective and safe in the diagnosis and management of choledocholithiasis and facilitate LC for symptomatic cholelithiasis. The procedures are also valuable in the diagnosis and management of most complications resulting from LC. (author)

    AIM: To investigate risk factors and adverse events related to high-dose diazepam administration during endoscopic submucosal dissection for gastric neoplasias. METHODS: Between February 2002 and December 2009, a total of 286 patients with gastric epithelial neoplasia underwent endoscopic submucosal dissection in our hospital. To achieve moderate sedation, 5-7.5 mg of diazepam was administered intravenously by non-anesthesiologists. Intermittent additional administration of 2.5-5 mg diazepam was performed if uncontrollable body movement of the patient was observed. All patients were classified into groups based on the required diazepam dose: low-dose (≤ 17.5 mg, n = 252) and high-dose (> 17.5 mg, n = 79). RESULTS: Differences between the low- and high-dose diazepam groups were observed in lifetime alcohol consumption (0.30 ± 0.48 vs 0.44 ± 0.52 tons, P = 0.032), body weight (58.4 ± 10.3 vs 62.0 ± 9.9 kg, P = 0.006), tumor size (15 ± 10 vs 23 ± 18 mm, P < 0.001), lesion location (P < 0.001) and the presence of ulcerative findings (14/238 vs 18/61, P < 0.001). Multivariate analysis identified all five variables as independently related to required diazepam dosage. In terms of adverse reactions to diazepam administration, paradoxical excitement was significantly more frequent in the high-dose diazepam group (P < 0.001). CONCLUSION: Intermittent administration of diazepam enabled safe completion of gastric endoscopic submucosal dissection except in patients who were alcohol abusers or obese, or who showed complicated lesions.

    Despite improvements in endoscopic hemostasis and pharmacological therapies, upper gastrointestinal (UGI) ulcers repeatedly bleed in 10% to 20% of patients, and those without early endoscopic reintervention or definitive surgery might be at a high risk for mortality. This study aimed to identify the risk factors for intractability to initial endoscopic hemostasis. We analyzed intractability among 428 patients who underwent emergency endoscopy for bleeding UGI ulcers within 24 hours of arrival at the hospital. Durable hemostasis was achieved in 354 patients by using initial endoscopic procedures. Sixty-nine patients with Forrest types Ia, Ib, IIa, and IIb at the second-look endoscopy were considered intractable to the initial endoscopic hemostasis. Multivariate analysis indicated that age ≥70 years (odds ratio [OR], 2.06; 95% confidence interval [CI], 1.07 to 4.03), shock on admission (OR, 5.26; 95% CI, 2.43 to 11.6), hemoglobin <8.0 mg/dL (OR, 2.80; 95% CI, 1.39 to 5.91), serum albumin <3.3 g/dL (OR, 2.23; 95% CI, 1.07 to 4.89), exposed vessels with a diameter of ≥2 mm on the bottom of ulcers (OR, 4.38; 95% CI, 1.25 to 7.01), and Forrest type Ia and Ib (OR, 2.21; 95% CI, 1.33 to 3.00) predicted intractable endoscopic hemostasis. Various factors contribute to intractable endoscopic hemostasis. Careful observation after endoscopic hemostasis is important for patients at a high risk for incomplete hemostasis.

Prasad Eye Institute, Hyderabad, India Purpose: The aims of this study were to report the preliminary experience of using telescopes, which were enabled for navigation guidance, and their utility in complex endoscopic lacrimal surgeries. Methods: Navigation enabling of the telescope was achieved by using the AxiEM™ malleable neuronavigation shunt stylet. Image-guided dacryolocalization was performed in five patients using the intraoperative image-guided StealthStation™ system in the electromagnetic mode. The “look ahead” protocol software was used to assist the surgeon in assessing the intraoperative geometric location of the endoscope and what lies ahead in real time. All patients underwent navigation-guided powered endoscopic dacryocystorhinostomy. The utility of uninterrupted navigation guidance throughout the surgery with the endoscope as the navigating tool was noted. Results: Intraoperative geometric localization of the lacrimal sac and the nasolacrimal duct could be easily deciphered. Constant orientation of the lacrimal drainage system and the peri-lacrimal anatomy was possible without the need for repeated point localizations throughout the surgery. The “look ahead” features could accurately alert the surgeon of anatomical structures that exists at 5, 10 and 15 mm in front of the endoscope. Good securing of the shunt stylet with the telescope was found to be essential for constant and accurate navigation. Conclusion: Navigation-enabled endoscopes provide the surgeon with the advantage of sustained stereotactic anatomical awareness at all times during the surgery. Keywords: telescope, endoscope, image guidance, navigation, lacrimal surgery, powered endoscopic DCR

    Full Text Available Background: Helicobacter pylori (H. pylori infection causes various abnormalities in the stomach. Only particular strain can cause severe problems in the stomach. CagA is a microbial virulent factor which is associated with more severe stomach problems, such as: peptic ulcer and stomach cancer. We would like to know the prevalence of CagA in Balinese population, and the association of H. Pylori CagA status with the severity of endoscopic appearance in dyspepsia patients. Method: Study design being used was analytic cross sectional study, involving 71 dyspepsia patients who underwent upper gastrointestinal endoscopic examination in Surya Husada Hospital and Balimed Hospital in June-December 2013. Sample was chosen in consecutive manner. Later, polymerase chain reaction (PCR examinations of the stomach mucous biopsy tissue to determine H. pylori infection status and CagA status were performed. Further, Chi square test was used to identify the difference in proportion of H. pylori and CagA between mild and severe endoscopic appearance. Results: In this study, we found that the prevalence of H. pylori infection was 22.5% using PCR examination. Prevalence of CagA positive in H. pylori positive was 62.5%. There was significant association between status of H. Pylori infection and severity of endoscopic appearance (p = 0.038; OR= 2.67; 95% CI = 1.18-6.05. Status of CagA in H. pylori infected patients was not associated with the severity of endoscopic appearance. Additionally, there was significant association between patients’ age and severity of endoscopic appearance. Conclusion: The prevalence of CagA in H. pylori positive was 62.5%. H. pylori infection was associated with severity of endoscopic appearance and CagA status in H. pylori infected patients was not associated with severity of endoscopic appearance.

    Introduction: Due to the unavailability of suitable endoscopic instruments, pediatric patients have not benefited fully from the technological advances in the endoscopic management of the upper urinary tract. This limitation may be overcome with the Holmuim:Yttrium-Aluminum-Garnet(Ho:YAG) laser delivered via small instruments. To date, there is no published report on the use of this modality in children. Purpose: We evaluated the indications, efficacy, and complications of endourological Ho:YAG laser surgery in the treatment of pediatric urolithiasis, posterior urethral valves, ureterocele and ureteropelvic junction obstruction. Methods: The patient population included 10 children with renal, ureteral and bladder calculi, 2 children with posterior urethral valves, 2 children with obstructing ureteroceles, 2 children with ureteropelvic junction obstruction and 1 child with a urethral stricture. Access to the lesions was either antegrade via a percutaneous nephrostomy tract or retrograde via the urethra. A solid state Ho:YAG laser with maximum output of 30 watts (New Star lasers, Auburn, CA) was utilized as the energy source. Results: A total of 10 patients underwent laser lithotripsy. The means age of the patients was 9 yrs (5-13 yrs). The average surface area of the calculi as 425.2 mm2 (92-1645 mm2). 8 of the patients required one procedure to render them stone free, one patient had a staghorn calculus filling every calyx of a solitary kidney requiring multiple treatments and one other patient with a staghorn calculus required 2 treatments. There were no complications related to the laser lithotripsy. Two newborn underwent successful ablation of po sterious urethral valves. Two infants underwent incision of obstructing ureteroceles with decompression of the ureterocele on postoperative ultrasound. Two children underwent endypyelotomy for ureteropelvic junction obstruction. One was successful an done required an open procedure to correct the obstruction. One child

    Endoscopy can observe the anatomical components in a deeply located and/or hidden area during neurosurgical procedures under the operating microscope. We have newly developed a flexible ultrathin endoscope integrated with irrigation suction apparatus (FUEISA) to visualize deeply located and/or hidden areas for assisting microneurosurgery. The present study investigated the usefulness of the FUEISA system for direct clipping surgery of cerebral aneurysms. Twenty-one patients underwent microneurosurgery assisted with the FUEISA system for direct clipping of cerebral aneurysms. The flexible ultrathin endoscope (outer diameter 0.75mm) consists of an image guide (6000 dpi) and a light guide, integrated with the irrigation suction apparatus. This endoscopic system was inserted before and after clipping to observe the anatomical conditions surrounding the lesions. In all cases, handling and operation of the FUEISA was technically successful during the surgical procedure. The ultrathin endoscope was adequately integrated with the irrigation suction apparatus in all cases. General anatomy visualization including the lenticulostriate arteries, medial striate arteries, and/or internal carotid artery perforators was possible, and the correct clip positioning and vessel conditions were easily checked. The endoscope revealed that the clip had been positioned incorrectly in one case. No complications associated with the endoscopic system occurred. The FUEISA system can be applied with safe manipulation, which was remarkably useful for confirmation of the presence of perforators and cranial nerves behind the lesions, particularly anatomical components located in deep and/or hidden areas during clipping of cerebral aneurysms.

    A potentially less-invasive technique, transluminal surgery, may reduce or eliminate pain and decrease time to full return of activities after abdominal operations. Inguinal hernia repair is perfectly suited to the transgastric endoscopic approach and has not been previously reported. Our purpose was to evaluate the feasibility of transgastric bilateral inguinal herniorrhaphy (BIH). Feasibility study with a nonsurvival canine model. Under general anesthesia, male mongrel dogs weighing 20 to 30 kg had a dual-channel endoscope introduced into the peritoneal cavity over a percutaneously placed guidewire. An overtube with an insufflation channel was used. Peritoneoscopy was performed, and bilateral deep and superficial inguinal rings were identified. The endoscope was removed, premounted with a 4 x 6 cm acellular human dermal implant and then readvanced intraperitoneally through the overtube. The implant was then deployed across the entire myopectineal orifice and draped over the cord structures. Bioglue was then applied endoscopically, and the implant was attached to the peritoneum. After completion of bilateral repairs, the animals were killed and necropsy performed. Five dogs underwent pure natural orifice transluminal endoscopic surgery (NOTES) intraperitoneal onlay mesh (IPOM) BIH. Accurate placement and adequate myopectineal coverage was accomplished in all subjects. At necropsy no injuries to the major structures were noted but Bioglue misapplication with contamination of unintended sites did occur. Our study involved only a small number of subjects in nonsurvival experiments, and no gastric closure was used. Many of the characteristics of inguinal hernia repair are especially well suited to the transgastric approach. The repair is in line with the transgastric endoscope vector, bilateral defects are adjacent, and the IPOM technique does not require significant manipulation or novel instrumentation.

    Full Text Available A 46-year-old man with severe back pain visited our hospital. Magnetic resonance imaging revealed extensive bone metastasis and rectal wall thickness. Colonoscopy revealed circumferential stenosis with edematous mucosa, suggesting colon cancer. However, histological findings of biopsy specimens revealed inflammatory cells but no malignant cells. The patient underwent endoscopic ultrasound, which demonstrated edematous wall thickness without destruction of the normal layer structure. After unsuccessful detection of neoplastic cells by boring biopsies, we performed endoscopic mucosal resection followed by boring biopsies that finally revealed signet ring cell carcinoma. Herein, we present a case and provide a review of the literature.

  12. Endoscopic management of bleeding peptic ulcers

    Peptic ulcers account for more than half of the cases of non variceal upper gastrointestinal (GI) bleeding and therefore, are the focus of most of the methods of endoscopic hemostasis. Surgical intervention is now largely reserved for patients in whom endoscopic hemostasis has failed. A variety of endoscopic techniques have been employed to stop bleeding and reduce the risk of rebleeding, with no major differences in outcome between these methods. These include injection therapy, fibrin injection, heater probe, mono polar electrocautery, bipolar electrocautery, lasers and mechanical hemo clipping. The most important factor in determining outcome after gastrointestinal bleeding is rebleeding or persistent bleeding. The endoscopic appearance of an ulcer, however, provides the most useful prognostic information for bleeding. Recurrent bleeding after initial endoscopic hemostasis occurs in 15-20% of patients with a bleeding peptic ulcer. The best approach to these patients remains controversial; the current options are repeat endoscopic therapy with the same or a different technique, emergency surgery or semi elective surgery after repeat endoscopic hemostasis. The combination of epinephrine injection with thermal coagulation may be more effective than epinephrine injection alone. Newer modalities such as fibrin injection or the application of hemo clips appear promising and comparative studies are awaited. (author)

  13. Endoscopic approaches to treatment of achalasia

    Endoscopic therapy for achalasia is directed at disrupting or weakening the lower esophageal sphincter (LES). The two most commonly utilized endoscopic interventions are large balloon pneumatic dilation (PD) and botulinum toxin injection (BTI). These interventions have been extensively scrutinized and compared with each other as well as with surgical disruption (myotomy) of the LES. PD is generally more effective in improving dysphagia in achalasia than BTI, with the latter reserved for infirm older people, and PD may approach treatment results attained with myotomy. However, PD may need to be repeated. Small balloon dilation and endoscopic stent placement for achalasia have only been used in select centers. Per oral endoscopic myotomy is a newer endoscopic modality that will likely change the treatment paradigm for achalasia. It arose from the field of natural orifice transluminal endoscopic surgery and represents a scarless endoscopic approach to Heller myotomy. This is a technique that requires extensive training and preparation and thus there should be rigorous accreditation and monitoring of outcomes to ensure safety and efficacy. PMID:23503707

    To assess anterior segment optical coherence tomographic measurements of patients after acute unilateral primary angle closure (APAC) compared with those of normal subjects. The clinical observational study included 41 hospital-based patients after unilateral APAC, their unaffected contralateral eyes, and 205 subjects. These were selected from the population-based Beijing Eye Study, and were matched with the APAC group for age, gender, and refractive error. All study participants underwent slit-lamp adapted optical coherence tomography (OCT). Compared with the unaffected contralateral eyes, eyes with APAC had a significantly shallower anterior chamber (P APAC and the unaffected contralateral eyes both showed more shallow anterior chambers (P APAC group, the anterior chamber angle was closed in three or more quadrants. Anterior segment OCT measurements show significant differences between eyes with APAC, contralateral eyes at risk for APAC, and normal eyes. This may open possibilities for a semi-automatic assessment of subjects at risk for APAC by anterior segment OCT. The anterior chamber angle was closed most often in the nasal quadrant, and, in APAC, the angle was closed in three or more quadrants.

    Endoscopic sphincterotomy (ES) is the standard technique for common bile duct (CBD) stone removal. Recently, endoscopic papillary large balloon dilation (EPLBD) has been shown to be a safe and effective technique for the removal of large CBD stone. The aim of this study was to determine the therapeutic outcomes and safety of EPLBD compared with ES for large CBD stone extraction. One hundred twenty-four patients with large bile duct stones were randomized into two groups, the first group included 61 patients subjected to EPLBD and the second group included 63 patients who underwent ES. We compared the success rate of stone removal, frequency of mechanical lithotripsy requirement, morbidity, and mortality. Baseline characteristics were not significantly different. The overall ductal clearance rate was ultimately similar between the EPLBD group (96.7%) and the ES group (93.7%) (P = .53), the one session ductal clearance rate was significantly different (86.9% versus 71.4%; P = .01). Requirement of mechanical lithotripsy was significantly different between the EPLBD and ES group (9.8% versus 17.5%, P = .04). There were no differences in complication rates between the EPLBD and ES group; pancreatitis, 4.9% versus 6.3%; minor hemorrhage, 1.6% versus 6.3%; acute cholangitis, 3.3% versus 1.9%; and recurrent stones, 3.3% versus 3.2%. The therapeutic outcomes of EPLBD for removal of large bile duct stones are better than those of ES with comparable complication rate. EPLBD is also recommended for removal of large CBD stone in patients with an underlying coagulopathy or need for anticoagulation following endoscopic retrograde cholangiopancreaticography.

    We report the case of a male patient, 80 years old, with a history of dyspepsia and no family history of neoplasias. In the upper digestive endoscopy in the distal esophagus, a flat depressed lesion with the appearance of early carcinoma, type IIC of Paris classification, was diagnosed by biopsy as a squamous carcinoma in situ, infiltrating, moderately differentiated non-keratinizing grade II carcinoma. He underwent submucosal endoscopic dissection without complications. Histopathology concluded: carcinoma of squamous cells, predominantly in situ of distal esophagus, measuring 0.6 cm, with focus of 0.1 cm of infiltration in the own lamina; absence of angiolymphatic or perineural invasion. The histopathology specimen had margins of surgical resection free of neoplasia. Stage pT1a. Three months later, in the endoscopy control with biopsy of the area, there was no evidence of carcinoma. We present the case because it is still a challenge to establish the diagnosis of esophageal cancer at an early stage, especially in patients without symptoms, highlighting the importance of chromoendoscopy and a good endoscopic examination to reach the diagnosis. Submucosal endoscopy dissection could be considered as a safe and effective alternative treatment to radical surgery.

    Buried bumper syndrome (BBS) is a rare complication developed after percutaneous endoscopic gastrostomy (PEG). We report a case of a 38-year-old male patient who sustained severe traumatic brain injury that was complicated with early BBS after PEG tube insertion. On admission, bedside PEG was performed, and 7 days later the patient developed signs of sepsis with rapid progression to septic shock and acute kidney injury. Abdominal CT scan revealed no collection or leakage of the contrast, but showed malpositioning of the tube bumper at the edge of the stomach and not inside of it. Diagnostic endoscopy revealed that the bumper was hidden in the posterolateral part of the stomach wall forming a tract inside of it, which confirmed the diagnosis of BBS. The patient underwent laparotomy with a repair of the stomach wall perforation, and the early postoperative course was uneventful. Acute BBS is a rare complication of PEG tube insertion which could be manifested with severe complications such as pressure necrosis, peritonitis and septic shock. Early identification is the mainstay to prevent such complications. Treatment selection is primarily guided by the presenting complications, ranging from simple endoscopic replacement to surgical laparotomy. PMID:27462190

  18. Endoscopic colostomy with percutaneous colopexy: an animal feasibility study

    Full Text Available Background: Indications for colostomy in colorectal diseases are obstruction of the large bowel, such as in cancer, diverticular disease in the acute phase, post-radiotherapy enteritis, complex perirectal fistulas, anorectal trauma and severe anal incontinence. Some critically ill patients cannot tolerate an exploratory laparotomy, and laparoscopic assisted colostomy also requires general anesthesia. Objective: To evaluate the feasibility, safety and efficacy of performing colostomy assisted by colonoscopy and percutaneous colopexy. Materials and methods: Five pigs underwent endoscopic assisted colostomy with percutaneous colopexy. Animals were evaluated in post-operative days 1, 2, 5 and 7 for feeding acceptance and colostomy characteristics. On day 7 full colonoscopy was performed on animals followed by exploratory laparotomy. Results: Average procedure time was 27 minutes (21-54 min. Postoperative mobility and feeding of animals were immediate after anesthesia recovery. Position of the colostomy, edges color, appearance of periostomal area, as well as its function was satisfactory in four animals. Retraction of colostomy was present in one pig. The colonoscopy and laparotomy control on the seventh day were considered as normal. A bladder perforation that was successfully repaired through the colostomy incision occurred in one pig. The main limitation of this study is its experimental nature. Conclusion: Endoscopic assisted colostomy with percutaneous colopexy proves to be a safe and effective method with low morbidity for performing colostomy in experimental animals, with possible clinical application in humans.

    Full Text Available Laryngeal and tracheal tumors are rare in pets; some piece of information on their disease behavior, therapy and evolution are limited. Neoplasms in this area are a diagnostic challenge. In many cases, they can be biopsied and excised using endoscopic instruments, but there is no report of this in canines. The goal of this study is to report a successful case of a laryngeal neoplasm removal through endoscopy. A head and neck radiogram revealed a mass in the laryngeal lumen protruding into the trachea. The patient then underwent an endoscopy to confirm the radiographic diagnosis and to surgically remove the tumor. The histopathological diagnosis was poorly differentiated carcinoma. The most appropriate treatment for laryngeal tumors is the resection of the submucosa or a partial laryngectomy however, partial and total laryngectomies are associated with many postoperative complications. In contrast, the endoscopic approach allows for highly magnified visualization of the lesion in situ, which facilitates the surgical removal of the mass through videosurgery. With little manipulation of the affected area, the chances of postoperative complications are reduced, leading to a more rapid recovery.

    Peritoneal entry (PE) during transanal endoscopic microsurgery (TEM) for tumors of the upper rectum is not an uncommon complication. The suture line of the rectal defect performed for PE is not devoid of leaks. Diagnostic laparoscopy after PE enables visualization and testing of the suture line. Here, we report the outcome of patients undergoing laparoscopy for PE following TEM. Data pertaining to patients undergoing laparoscopy for PE following TEM between 2004 and 2013 were retrospectively collected. One hundred and forty-one TEM procedures were performed, and 19 (13 %) with PE were included. The mean age was 68.1 ± 10.6 years, mean distance from the anal verge 12.5 ± 2 cm, and mean tumor size 2 cm. Lesions were located in the lateral wall (n = 14), anteriorly (n = 4), and posteriorly (n = 1). Indications for TEM were: adenoma (n = 13), indeterminate margins after polypectomy (n = 4, a submucosal lesion (n = 1), and a T1N0 adenocarcinoma (n = 1). In all patients, the rectal wall defect was closed primarily. Twelve patients underwent additional laparoscopy and suture line leak testing. In one patient, a small leak was detected which was repaired laparoscopically. In another, a hematoma of the suture line was observed and a drain was left in place. The mean operative time was 109 min (range 80-135 min) for TEM and 33 min (range 22-45 min) for laparoscopy. A diverting ileostomy was fashioned in one patient on postoperative day 3 after TEM without laparoscopy. No other major complications were observed. Laparoscopy after PE during TEM permits visualization and testing of the suture line. It is not associated with increased morbidity, and it may increase the safety of TEM.

    Full Text Available We studied the clinical presentation and management of four patients with anterior urethral valves; a rare cause of urethral obstruction in male children. One patient presented antenatally with oligohydramnios, bilateral hydronephrosis and bladder thickening suggestive of an infravesical obstruction. Two other patients presented postnatally at 1 and 2 years of age, respectively, with poor stream of urine since birth. The fourth patient presented at 9 years with frequency and dysuria. Diagnosis was established on either micturating cystourethrogram (MCU (in 2 or on cystoscopy (in 2. All patients had cystoscopic ablation of the valves. One patient developed a postablation stricture that was resected with an end-to-end urethroplasty. He had an associated bilateral vesicoureteric junction (VUJ obstruction for which a bilateral ureteric reimplantation was done at the same time. On long-term follow-up, all patients demonstrated a good stream of urine. The renal function is normal. Patients are continent and free of urinary infections. Anterior urethral valves are rare obstructive lesions in male children. The degree of obstruction is variable, and so they may present with mild micturition difficulty or severe obstruction with hydroureteronephrosis and renal impairment. Hence, it is important to evaluate the anterior urethra in any male child with suspected infravesical obstruction. The diagnosis is established by MCU or cystoscopy and the treatment is always surgical, either a transurethral ablation or an open resection. The long-term prognosis is good.

    Obesity is a growing pandemic across the world. Dietary restrictions and behavior modifications alone have a limited benefit. Bariatric surgery, despite being the current gold standard, has limited acceptance by patients due to cost and associated morbidity. In our review, we have discussed nine original studies describing endoscopic sleeve gastroplasty (ESG). A total of 172 subjects successfully underwent ESG. Of 65 subjects with follow up data, 95.4% (62/65) had intact gastric sleeve confirmed via esophagogastroduodenoscopy or oral contrast study at the end of study specific follow up interval (the longest being 6 months). Individual studies reported a technical success rate for intact gastric sleeve from as low as 50% to as high as 100%. A statistically significant p ESG an attractive option to consider among other bariatric therapies.

    The purpose of this study was to compare the triple-bundle (TB) anterior cruciate ligament (ACL) reconstruction with the double-bundle (DB) ACL reconstruction in immediate postoperative anterior knee stability. This study involved 133 patients who had undergone the anatomic ACL reconstruction with autogenous hamstring tendon unilaterally. Then 83 patients (mean age, 28.8 years) underwent the DB between November 2004 and December 2005, and 50 patients (mean age, 29.6 years) underwent the TB ACL reconstruction between January and December 2006. The 2 femoral tunnels were created in the ideal ACL attachment area, whereas 2 tibial tunnels for the DB and 3 tunnels for the TB were created in the ACL footprint. The 2 doubled tendon grafts were fixed with EndoButton-CL (Smith & Nephew Endoscopy, Andover, MA) on the femur. The grafts were fixed to the tibia using a Double Spike Plate and a screw under the total initial tension of 20 N at 20° of flexion, after meticulous in situ pretensioning using a tensioning boot. Then immediate postoperative anterior knee laxity in response to 89 N of anterior load was measured by one experienced examiner (T.M.) with the KT-2000 Knee Arthrometer (MEDmedtric, San Diego, CA) under general anesthesia at 30° of knee flexion with muscle relaxants. The measured anterior laxity was 3.4 ± 1.2 mm in the DB and 2.5 ± 0.7 mm in the TB ACL reconstruction, a statistically significant difference. The side-to-side difference of the laxity was -3.2 ± 1.6 mm in the DB and -4.2 ± 2.0 mm in the TB, again a significant difference. TB ACL reconstruction resulted in better immediate postoperative anterior knee stability than DB ACL reconstruction under 89 N of anterior tibial load (P = .031).

    Post lumbar laminectomy syndrome with its resultant chronic low back pain is estimated to occur in 20% to 50% of the patients. Among various procedures available, lysis of epidural adhesions is considered as one of the effective therapeutic modalities of management in these patients, and may be performed either non-endoscopically or endoscopically. This retrospective evaluation included 120 post lumbar laminectomy patients who underwent either non-endoscopic adhesiolysis (Group I) or endoscopic adhesiolysis (Group II) with 60 consecutive patients in each group. The quality of pain relief when greater than 50% was considered significant. Results showed all patients experienced significant relief following both procedures even though the number of patients experiencing significant relief decreased with both techniques over a time period. Overall relief with the first procedure (mean + SEM) was 12 + 3.2 weeks for Group I, and it was 20 + 2.9 weeks for Group II with significantly longer improvement in Group II than Group I. At one year follow up, the results showed that with repeat procedures, 72% in Group I and 40% in Group II experienced significant relief at 6 months, whereas at 12 months, it decreased to 52% in Group I and 22% in Group II, with a significantly greater number of patients experiencing relief at 6 months and 12 months in Group I, than Group II, even though Group I patients underwent a greater number of procedures. Cost effectiveness analysis showed Group I patients experiencing significant relief at a cost of $40 per week, with one year quality of life improvement for $2,080, whereas it was $135 per week improvement in Group II with a one year quality of life improvement at a cost of $7,020 with significant difference noted in cost effectiveness. In conclusion, non-endoscopic epidural adhesiolysis and administration of corticosteroids and hypertonic saline is a safe and cost effective procedure for relieving chronic intractable pain in post lumbar

    Endoscopic resection has proven highly effective and safe in the removal of focal early neoplastic lesions in Barrett's esophagus and is considered the cornerstone of endoscopic treatment. Several techniques are available for endoscopic resection in Barrett's esophagus. The most widely used technique for piecemeal resection of early Barrett's neoplasia is the ligate-and-cut technique. Newer techniques such as endoscopic submucosal dissection may also play a role in the treatment of neoplastic Barrett's esophagus. Treatment of early Barrett's neoplasia should be centralized and limited to expert centers with a high-volume load and sufficient expertise in the detection and treatment of esophageal neoplasia.

    Giant pituitary adenomas (> 4 cm in maximum diameter) represent a significant surgical challenge. Endoscopic endonasal surgery (EES) has recently been introduced as a treatment option for these tumors. The authors present the results of EES for giant adenomas and analyze the advantages and limitations of this technique. The authors retrospectively reviewed the medical files and imaging studies of 54 patients with giant pituitary adenomas who underwent EES and studied the factors affecting surgical outcome. Preoperative visual impairment was present in 45 patients (83%) and partial or complete pituitary deficiency in 28 cases (52%), and 7 patients (13%) presented with apoplexy. Near-total resection (> 90%) was achieved in 36 patients (66.7%). Vision was improved or normalized in 36 cases (80%) and worsened in 2 cases due to apoplexy of residual tumor. Significant factors that limited the degree of resection were a multilobular configuration of the adenoma (p = 0.002) and extension to the middle fossa (p = 0.045). Cavernous sinus invasion, tumor size, and intraventricular or posterior fossa extension did not influence the surgical outcome. Complications included apoplexy of residual adenoma (3.7%), permanent diabetes insipidus (9.6%), new pituitary insufficiency (16.7%), and CSF leak (16.7%, which was reduced to 7.4% in recent years). Fourteen patients underwent radiation therapy after EES for residual mass or, in a later stage, for recurrence, and 10 with functional pituitary adenomas received medical treatment. During a mean follow-up of 37.9 months (range 1-114 months), 7 patients were reoperated on for tumor recurrence. Three patients were lost to follow-up. Endoscopic endonasal surgery provides effective initial management of giant pituitary adenomas with favorable results compared with traditional microscopic transsphenoidal and transcranial approaches.

    Full Text Available Abstract Background The incidence of undetected radiographically iatrogenic longitudinal splitting in the anterior cortex during intramedullary nailing of the femur has not been well documented. Methods Cadaveric study using nine pairs of fresh-frozen femora from adult cadavers. The nine pairs of femora underwent a standardized antegrade intramedullary nailing and the detection of iatrogenic lesions, if any, was performed macroscopically and by radiographic control. Results Longitudinal splitting in the anterior cortex was revealed in 5 of 18 cadaver femora macroscopically. Anterior splitting was not detectable in radiographic control. Conclusion Longitudinal splitting in the anterior cortex during intramedullary nailing of the femur cannot be detected radiographically.

  10. Late spontaneous resolution of a double anterior chamber post deep anterior lamellar keratoplasty

    2017-01-01

    Full Text Available A 31-year-old healthy male underwent deep anterior lamellar keratoplasty with big-bubble technique for treatment of keratoconus in his right eye. One week after surgery, he presented with detachment of the endothelium-Descemet complex with formation of a double anterior chamber, despite the apparent absence of an intraoperative Descemet membrane rupture. A subsequent intervention with the intent to relocate the corneal graft button was not effective, because the detachment appeared again one day later. The authors hypothesized that, at the time of the stromal dissection with big bubble technique, a small amount of air penetrated into the anterior chamber, creating a false pathway through the trabecular meshwork. The aqueous humor then penetrated the graft flowing through the false pathway, causing the endothelium-Descemet detachment. The persistence of that pathway, even after the intervention of graft repositioning, caused the failure of the latter procedure and persistence of the double chamber. We decided to wait and observe. The double anterior chamber spontaneously resolved in approximately three months.

    Per-oral endoscopic myotomy (POEM) requires advanced flexible endoscopic skills, especially in the management of complications. We present a full-thickness esophagotomy while performing POEM and repair using an endoscopic suturing device. An anterior esophageal 2 cm mucosectomy is created 7-10 cm proximal to the gastroesophageal junction after a submucosal wheal is raised. A submucosal tunnel is created and extended to 2 cm on the gastric cardia. A selective circular myotomy is performed. The mucosectomy is closed using endoscopic clips. An inadvertent full-thickness esophagotomy was created while performing the mucosotomy on an inadequate submucosal wheal. We were able to resume the POEM technique at the initial esophagotomy site. There was a discussion to convert to laparoscopy. However, as we succeeded in creating the tunnel, we continued with the POEM technique. After the selective myotomy was completed, we used an endoluminal suturing device (Overstitch, Apollo Endosurgery, Austin TX) to close the full-thickness esophagotomy in two layers (muscular, mucosal). A covered stent was not an option because the esophagus was dilated, which precluded adequate apposition. The patient had an uneventful postoperative course. At 9-month follow-up, had excellent palliation of dysphagia without reflux. This case demonstrates the importance of identifying extramucosal intrathoracic anatomy, thus emphasizing the need for an experienced surgeon to perform these procedures, or at a minimum to be highly involved. Raising an adequate wheal is crucial before mucosectomy. Inadequacy of the wheal may reflect local esophageal fibrosis. If this fails at multiple locations in the esophagus, it may be prudent to convert to laparoscopy. This case also demonstrates the need for advanced flexible endoscopic therapeutic tools and a multidisciplinary approach to manage potential complications.

    To evaluate the outcomes of endoscopic treatment of vesicoureteral reflux (VUR) performed on infants, and to discuss the possible role of this approach in selected cases. A retrospective analysis was conducted on the patients who underwent endoscopic injection of a bulking substance for VUR in our institution, and a comparison was made with patients treated during infancy and those treated later in life. A total of 463 ureteral units were included (296 children), of whom 47 were patients less than 1 year of age (infants, INF group); the remaining 416 were included in a second group (children, CHL). In this study, the percentage of high-grade VUR and presence of reflux nephropathy were significantly higher in younger patients. Both early failure and recurrence rate were significantly higher in the INF group when compared with the CHL group. No complications were observed in the INF group. Endoscopic treatment of VUR is feasible in patients less than 1 year of age. The effectiveness is lower than when patients are treated at a later age but was still over 80% in our series. There were no complications reported related to the procedure itself or to the general anesthesia. Once it is known that endoscopic treatment of VUR can be performed, controversy arises about the indication of treating patients with VUR. Careful selection of VUR cases that are less likely to spontaneously resolve, presence of breakthrough infections, and parental preference, all play a role in the decision-making process.

    Per-oral endoscopic myotomy (POEM) is a minimally invasive endoscopic treatment option for patients with achalasia and has been performed since 2010. It is less invasive than Heller myotomy and its use is spreading rapidly worldwide. We present our results of POEM that, to the best of our knowledge, are the first cases in Turkey. We enrolled patients between May 2014 and September 2014; 8 patients with achalasia whose complaints recurred after pneumatic balloon dilatation underwent POEM. The procedure was performed under general anesthesia at the endoscopy unit of the gastroenterology clinic. Demographic data was recorded before the procedure, and the results of the procedure were recorded prospectively. The median age of the patients was 42.5 (30-72) years. Preoperative and postoperative median Eckardt scores were 10 (8-12) and 1 (0-2), respectively. The median total duration of the procedure was 101 (71-158) min, and the median myotomy length was 13.5 (10-16) cm. Postoperative oral intake started on median day 1 (1-2) and the length of hospital stay was 4 (3-6) days. In 2 patients, capnoperitoneum developed during the procedure and was treated with a Veress needle. POEM is a safe endoscopic treatment modality for patients with achalasia in centers that are experienced in advanced endoscopic techniques.

    This paper reports an unusual case of a transsphenoidal encephalocele and discusses our experience with a minimally invasive management. To the best of our knowledge, we present the first case of a combined endoscopic transnasal and transoral approach to a transsphenoidal encephalocele in an infant. A 17-day-old boy, who was referred for further assessment of upper airway obstruction, presented with respiratory distress and feeding difficulties. Bronchoscopy and imaging revealed a transsphenoidal encephalocele. At the age of 48 days, he underwent a combined endoscopic transnasal and transoral excision of the nasal component of the encephalocele. This approach, with the aid of neuronavigation, allows good demarcation of the extra-cranial neck of the transsphenoidal encephalocele. We were able to cauterize and carefully dissect the sac prior to excision. The defect of the neck was clearly visualized, and Valsalva manoeuvre was performed to exclude any CSF leak. As the defect was small, it was allowed to heal by secondary intention. The patient's recovery was uneventful, and he tolerated full feeds orally on day 2. Postoperative imaging demonstrated no evidence of recurrence of the nasal encephalocele. Endoscopic follow-up showed good healing of the mucosa and no cerebrospinal fluid leak. The surgical management of transsphenoidal encephalocele in neonates and infants is challenging. We describe a safe technique with low morbidity in managing such a condition. The combined endoscopic transnasal and transoral approach with neuronavigation is a minimally invasive, safe and feasible alternative, even for children below 1 year of age.

    Explore the possibility of an endoscopic urethroplasty with a free graft on a biodegradable, self-reinforced polyglycolic acid spiral stent. Urethral strictures, failures of previous urethrotomies, which still can be incised endoscopically are selected. Strong fibrotic strictures which are bad indications for the use of a free graft are excluded. A free graft (skin on mucosa) is sutured around the stent and brought at the place of the endoscopically opened stricture where the graft is fixed with a suture through skin, bulbar muscles and spongiosum. A suprapubic diversion is left for 10 days. The stent keeps the graft in contact with surrounding well vascularized tissue where it can take. Other parts of the graft become necrotic. The stent hydrolyses in about 3 weeks. 10 patients with bulbar strictures from 2 to 4 cm in length and failed previous urethrotomies were treated successfully with this technique. The follow-up varies from 39 to 3 months (mean: 21 months). After 2 years 1 stricture recurred in a man who underwent regular endoscopies for recurrent bladder tumors. All other patients were successful until now. One stent got lost in the bladder during the procedure but could be brought at the right place. Other complications were 1 hematuria, 1 urosepsis, 1 perineal pain, 1 painful evacuation of a part of the stent 16 days after operation, and 1 difficult micturition. The preliminary experiences indicate that this technique is a possible treatment of short bulbar strictures after failure of endoscopic treatment.

    To examine the outcomes of renal ultrasound studies after subureteral injection of dextranomer/hyaluronic acid copolymer and provide recommendations for postoperative management of vesicoureteral reflux (VUR). Pediatric patients aged 15 years or younger with uncomplicated primary VUR were recruited for endoscopic treatment with dextranomer/hyaluronic acid gel. After undergoing the procedure, patients were instructed to continue prophylactic antibiotic treatment until a follow-up voiding cystourethrogram was obtained 2 weeks or more after treatment. VUR resolution was defined as grade 0. Repeat endoscopic injection was offered to patients with persistent VUR. Postoperative renal ultrasound scans were obtained on the same day as the voiding cystourethrogram. Of 120 patients treated, 6 were lost to follow-up and 14 had not yet undergone the posttreatment evaluation. The 100 remaining patients (efficacy population) had a mean age of 4.2 years (range 0.5 to 15), and the median reflux grade was 2 (range 1 to 5). The overall VUR resolution rate for the patients was 87% after endoscopic injection. Of 100 patients, 88 achieved complete resolution after a single injection and 19 required a repeat injection. Of the 100 patients who underwent postoperative ultrasound examination, none demonstrated renal ultrasound changes consistent with significant ureteral obstruction or renal parenchymal changes. Renal ultrasound studies after endoscopic treatment with dextranomer/hyaluronic acid gel are unnecessary after determination of reflux resolution by voiding cystourethrography.

    Vesicoureteral reflux (VUR) is a common anomaly affecting 1-3% of all children and 30-50% of those with urinary tract infection (UTI). In the past febrile vesicoureteric reflux on chronic antibiotic prophylaxis were treated by open surgery. Now a day's endoscopic injection of a bulking material has replaced open surgical procedure in cases of primary VUR. Our objective was to assess the efficacy of endoscopic treatment for primary vesico-ureteric reflux in children. Methods: This was a descriptive case series. One hundred and five patients with either unilateral or bilateral VUR (181 ureters) underwent endoscopic treatment for primary VUR between January 2011 and January 2014. Children from 1 to 12 years of age with grade-II to IV reflux on preoperative voiding cystourethrogram (VCUG) were enrolled through consecutive non-probability sampling. Efficacy of treatment was evaluated at three months post injection by a standard VCUG. Ureters with no or grade-I reflux were considered successful treatment. Results: Out of 105 patients 76 had bilateral while 29 had unilateral reflux. Mean age was 5.7 years (SD±.7). Among 181 refluxing ureters, 116 (64%) were free of reflux, while 49 (27%) showed down gradation and 16 (8.8%) showed no response to treatment on postoperative VCUG. Conclusion: Endoscopic treatment for VUR is a viable option for patients with primary VUR and may be considered in management of such cases. (author)

    Delayed recovery after facial palsy results in aberrant nerve regeneration with symptomatic movement disorders, summarized as the postparalytic facial nerve syndrome. The authors present an alternative surgical approach for improvement of periocular movement disorders in patients with postparalytic facial nerve syndrome. The authors proposed that endoscopic brow lift leads to an improvement of periocular movement disorders by reducing pathologically raised levels of afferent input. Eleven patients (seven women and four men) with a mean age of 54 years (range, 33 to 85 years) and with postparalytic facial nerve syndrome underwent endoscopic brow lift under general anesthesia. Patients' preoperative condition was compared with their postoperative condition using a retrospective questionnaire. Subjects were also asked to compare the therapeutic effectiveness of endoscopic brow lift and botulinum toxin type A. Mean follow-up was 52 months (range, 22 to 83 months). No intraoperative or postoperative complications occurred. During follow-up, patients and physicians observed an improvement of periorbital contractures and oculofacial synkinesis. Scores on quality of life improved significantly after endoscopic brow lift. Best results were obtained when botulinum toxin type A was adjoined after the endoscopic brow lift. Patients described a cumulative therapeutic effect. These findings suggest endoscopic brow lift as a promising additional treatment modality for the treatment of periocular postparalytic facial nerve syndrome-related symptoms, leading to an improved quality of life. Even though further prospective investigation is needed, a combination of endoscopic brow lift and postsurgical botulinum toxin type A administration could become a new therapeutic standard.

  19. Endoscopic-assisted treatment of trigonocephaly.

    2012-09-01

    Minimally invasive, endoscopic repair of metopic craniosynostosis has emerged as a potentially efficacious, safe, and aesthetically acceptable alternative to open procedures. Potential advantages of an early endoscopic approach to repair metopic craniosynostosis include a reduction in blood loss and consequent decreases in transfusion volumes, decreased hospital costs, shorter operative times, and limited duration of hospitalization. Other benefits of minimally invasive techniques would be avoidance of anaesthetic surgical scarring, decrease in postoperative swelling and discomfort, and lower rate of complications such as duramater tears, postoperative hyperthermia, or infection. However, a concern is usually raised about the achievements of the "endoscopic" techniques when compared to "standard" open approaches. The indications for endoscopic-assisted surgery in the treatment of trigonocephaly remain controversial and further series and follow-up of these patients are necessary to set up the role of these approaches.

    Surgical exposure of lesions located along the ventral foramen magnum (FM) and clivus poses a unique set of challenges to neurosurgeons. Several approaches have been developed to access these regions with varying degrees of exposure and approach-related morbidity. To describe the microsurgical anatomy of the high anterior cervical approach to the clivus and foramen magnum, and describe novel skull base extensions of the approach. Eight adult cadaveric specimens were included in this study. The high anterior cervical approach includes a minimal anterior clivectomy and its lateral skull base extensions: the extended anterior far-lateral clivectomy and the inferior petrosectomy. The microsurgical anatomy and exposure of the various extensions of the approach were analyzed. In addition, the capability of complementary endoscopy was evaluated. With proper positioning, the minimal anterior clivectomy exposed the vertebrobasilar junction, proximal basilar artery, anteroinferior cerebellar arteries, and 6th cranial nerve. The lateral skull base extensions provided access to the anterior FM, mid-lower clivus, and petroclival region, up to the Meckel cave, contralateral to the side of the surgical approach. The high anterior cervical approach with skull base extensions is an alternative to the classic approaches to the ventral FM and mid-lower clivus. A minimal anterior clivectomy provides access to the midline mid-lower clivus. The addition of an extended anterior far-lateral clivectomy and an inferior petrosectomy extends the exposure to the anterior FM and cerebellopontine angle lying anterior to the cranial nerves. The approach is also ideally suited for endoscopic-assisted techniques.

    Endoscopic therapy for achalasia is directed at disrupting or weakening the lower esophageal sphincter (LES). The two most commonly utilized endoscopic interventions are large balloon pneumatic dilation (PD) and botulinum toxin injection (BTI). These interventions have been extensively scrutinized and compared with each other as well as with surgical disruption (myotomy) of the LES. PD is generally more effective in improving dysphagia in achalasia than BTI, with the latter reserved for infir...

    Acute appendicitis is the most common abdominal emergency, but the diagnosis of appendicitis remains a challenge. Endoscopic retrograde appendicitis therapy (ERAT) is a new and minimally invasive procedure for the diagnosis and treatment of acute appendicitis. To investigate the diagnostic value of ERAT for acute appendicitis by the combination of colonoscopy and endoscopic retrograde appendicography (ERA). Twenty-one patients with the diagnosis of suspected uncomplicated acute appendicitis who underwent ERAT between November 2014 and January 2015 were included in this study. The main outcomes, imaging findings of acute appendicitis including colonoscopic direct-vision imaging and fluoroscopic ERA imaging, were retrospectively reviewed. Secondary outcomes included mean operative time, mean hospital stay, rate of complication, rate of appendectomy during follow-up period, and other clinical data. The diagnosis of acute appendicitis was established in 20 patients by positive ERA (5 patients) or colonoscopy (1 patient) alone or both (14 patients). The main colonoscopic imaging findings included mucosal inflammation (15/20, 75 %), appendicoliths (14/20, 70 %), and maturation (5/20, 25 %). The key points of ERA for diagnosing acute appendicitis included radiographic changes of appendix (17/20, 85 %), intraluminal appendicoliths (14/20, 70 %), and perforation (1/20, 5 %). Mean operative time of ERAT was 49.7 min, and mean hospital stay was 3.3 days. No patient converted to emergency appendectomy. Perforation occurred in one patient after appendicoliths removal was not severe and did not require invasive procedures. During at least 1-year follow-up period, only one patient underwent laparoscopic appendectomy. ERAT is a valuable procedure of choice providing a precise yield of diagnostic information for patients with suspected acute appendicitis by combination of colonoscopy and ERA.

    Endoscopic variceal sclerotherapy (EVS) has been considered the mainstay of therapy for bleeding esophageal varices in adults. However, recent data have shown that endoscopic variceal ligation (EVL) is just as efficacious and has fewer complications than EVS. Although there are many reports concerning EVL in adults, only a few studies have been done in children. This report describes experience with EVL in 22 children with esophageal variceal hemorrhage. Eighty-seven EVL procedures were performed during a 9-year period in 22 children. The causes of portal hypertension were biliary atresia (10), portal vein thrombosis (8), chronic active hepatitis (1), cirrhosis secondary to cystic fibrosis (2), and primary sclerosing cholangitis (1). The age range at the onset of variceal bleeding was 8 months to 19 years. Twelve patients had EVS before EVL treatment was begun. Distal esophageal varices (one to four per session) were mechanically ligated using an elastic band ligature device attached to a flexible endoscope. The aim of therapy was obliteration of distal esophageal varices by EVL, every 2 to 4 weeks, until eradication. Subsequent EVL was dictated by the status of the varices. Outcome was assessed with respect to survival, rebleeding, status of varices, and complications. The patients underwent a mean of four sessions of EVL (range, one to eight). Four patients subsequently underwent liver transplantation. Of the 18 patients remaining (average follow-up period, 5.3 years), 12 had their varices eradicated (average of four EVL sessions), four are still in treatment, one has not been evaluated in the past 4 years, and one died of liver failure. Complications included bleeding between sessions (6 patients), cervical esophageal perforation (1 patient), and transient fever (2 patients). No child has experienced symptoms of esophageal stenosis or gastroesophageal reflux. Two patients died of liver disease, unrelated to bleeding from portal hypertension. EVL is effective in

    To clarify the endoscopic mucosal change of the stomach caused by Lugol's iodine solution spray on screening esophagogastroduodenoscopy (EGD). Sixty-four consecutive patients who underwent EGD for esophageal squamous cell carcinoma screening were included in this study. The records for these patients included gastric mucosa findings before and after Lugol's iodine solution was sprayed. The endoscopic findings of the greater curvature of the gastric body were retrospectively analyzed based on the following findings: fold thickening, exudates, ulcers, and hemorrhage. Mucosal changes occurred after Lugol's solution spray totally in 51 patients (80%). Fold thickening was observed in all 51 patients (80%), and a reticular pattern of white lines was found on the surface of the thickened gastric folds found in 28 of the patients (44%). Exudates were observed in 6 patients (9%). The gastric mucosa could be affected by Lugol's iodine; the most frequent endoscopic finding of this effect is gastric fold thickening, which should not be misdiagnosed as a severe gastric disease.

    Introduction. The purpose of the present contribution is to perform a detailed anatomic and virtual reality three-dimensional stereoscopic study in order to test the effectiveness of the extended endoscopic endonasal approaches for selected anterior and posterior circulation aneurysms. Methods. The study was divided in two main steps: (1) simulation step, using a dedicated Virtual Reality System (Dextroscope, Volume Interactions); (2) dissection step, in which the feasibility to reach specific vascular territory via the nose was verified in the anatomical laboratory. Results. Good visualization and proximal and distal vascular control of the main midline anterior and posterior circulation territory were achieved during the simulation step as well as in the dissection step (anterior communicating complex, internal carotid, ophthalmic, superior hypophyseal, posterior cerebral and posterior communicating, basilar, superior cerebellar, anterior inferior cerebellar, vertebral, and posterior inferior cerebellar arteries). Conclusion. The present contribution is intended as strictly anatomic study in which we highlighted some specific anterior and posterior circulation aneurysms that can be reached via the nose. For clinical applications of these approaches, some relevant complications, mainly related to the endonasal route, such as proximal and distal vascular control, major arterial bleeding, postoperative cerebrospinal fluid leak, and olfactory disturbances must be considered.

    Anterior knee pain is a common complain in all ages athletes. It may be caused by a large variety of injuries. There is a continuum of diagnoses and most of the disorders are closely related. Repeated minor trauma and overuse play an important role for the development of lesions in Hoffa's pad, extensor mechanism, lateral and medial restrain structures or cartilage surface, however usually an increase or change of activity is referred. Although the direct relation of cartilage lesions, especially chondral, and pain is a subject of debate these lesions may be responsible of early osteoarthrosis and can determine athlete's prognosis. The anatomy and biomechanics of patellofemoral joint is complex and symptoms are often unspecific. Transient patellar dislocation has MR distinct features that provide evidence of prior dislocation and rules our complication. However, anterior knee pain more often is related to overuse and repeated minor trauma. Patella and quadriceps tendon have been also implicated in anterior knee pain, as well as lateral or medial restraint structures and Hoffa's pad. US and MR are excellent tools for the diagnosis of superficial tendons, the advantage of MR is that permits to rule out other sources of intraarticular derangements. Due to the complex anatomy and biomechanic of patellofemoral joint maltracking is not fully understood; plain films and CT allow the study of malalignment, new CT and MR kinematic studies have promising results but further studies are needed. Our purpose here is to describe how imaging techniques can be helpful in precisely defining the origin of the patient's complaint and thus improve understanding and management of these injuries.

    Endoscopic ultrasonography (EUS) is an established diagnostic modality for diagnosing common bile duct (CBD) stones. Its use has led to a reduction in the number of endoscopic retrograde cholangiopancreatography (ERCP) procedures performed for suspected choledocholithiasis. We aimed to explore the role of EUS in detecting CBD stones and/or sludge in common gastroenterology practice. We reviewed case records of 268 consecutive patients who underwent (EUS) procedures performed to confirm or rule out the presence of CBD stones and/or sludge between November 2006 and January 2011 in the Reinier de Graaf Hospital, Delft, The Netherlands, which is a nonacademic community hospital. On the basis of EUS findings, 169 of 268 (63%) patients did not undergo ERCP and were therefore not exposed to its risk of complications. Patients with positive findings on EUS (n=99) all underwent ERCP and endoscopic sphincterotomy. Only 57 of 99 (58%) had positive findings at ERCP. The main contributing factors to this finding seem to be time interval between EUS and ERCP and the type of CBD content (i.e. sludge, one CBD stone or more than one CBD stone) described. In our common gastroenterology practice, EUS plays an important role in selecting patients suspected to have CBD stones or sludge for ERCP. Much is to be learned about the probability of spontaneous passage of CBD stones and sludge into the duodenum.

    Full Text Available Introduction: Epistaxis is one of the most common medical emergencies, making the management of posterior epistaxis a challenging problem for the ear, nose, and throat (ENT surgeon. In the cases of conservative management failure, ligation of the major arteries or percutaneous embolization of the maxillary artery is performed routinely in most units, but rates of failure and complications are high.The objective of this study was to assess the effectiveness of endoscopic sphenopalatine artery (SPA cauterization in patients with refractory posterior epistaxis.   Materials and Methods: Between April 2011 and January 2012, 27 patients (15 males and 12 females with refractory posterior epistaxis underwent endoscopic SPA cauterization in two tertiary referral hospitals in Shiraz. Three patients underwent bilateral cauterization.   Results: Four patients (from 30 arteries had new epistaxis after surgery, three experienced subsequent epistaxis requiring medical treatment, and one patient had a minor epistaxis not needing treatment.   Conclusion:  The SPA electrocoagulation technique seems to be safe, simple, fast, and effective with low rates of morbidity and complications for the management of refractory posterior epistaxis. Endoscopic SPA cauterization should be considered as an immediate second-line management when conservative treatment as first-line management fails.

    Full Text Available The anterior cingulate cortex (ACC has a role in attention, analysis of sensory information, error recognition, problem solving, detection of novelty, behavior, emotions, social relations, cognitive control, and regulation of visceral functions. This area is active whenever the individual feels some emotions, solves a problem, or analyzes the pros and cons of an action (if it is a right decision. Analogous areas are also found in higher mammals, especially whales, and they contain spindle neurons that enable complex social interactions. Disturbance of ACC activity is found in dementias, schizophrenia, depression, the obsessive-compulsive syndrome, and other neuropsychiatric diseases.

    To evaluate the feasibility of a unique prototype foot-controlled robotic-enabled endoscope holder (FREE) in functional endoscopic sinus surgery. Cadaveric study. Using human cadavers, we investigated the feasibility, advantages, and disadvantages of the robotic endoscope holder in performing endoscopic sinus surgery with two hands in five cadaver heads, mimicking a single nostril three-handed technique. The FREE robot is relatively easy to use. Setup was quick, taking less than 3 minutes from docking the robot at the head of the bed to visualizing the middle meatus. The unit is also relatively small, takes up little space, and currently has four degrees of freedom. The learning curve for using the foot control was short. The use of both hands was not hindered by the presence of the endoscope in the nasal cavity. The tremor filtration also aided in the smooth movement of the endoscope, with minimal collisions. The FREE endoscope holder in an ex-vivo cadaver test corroborated the feasibility of the robotic prototype, which allows for a two-handed approach to surgery equal to a single nostril three-handed technique without the holder that may reduce operating time. Further studies will be needed to evaluate its safety profile and use in other areas of endoscopic surgery. NA.

    Endoscopic ultrasound (EUS) and endoscopic resection play an important role in gastric submucosal tumor. However, there were few articles regarding EUS and endoscopic resection of gastric schwannomas. Our aim was to evaluate the role of EUS and endoscopic resection in treating gastric schwannomas.We retrospectively reviewed 14 patients between March 2012 and April 2016 with gastric schwannomas and who received EUS and endoscopic resection. EUS characteristics, endoscopic resection, tumor features, and follow-up were evaluated in all the patients.Fourteen patients were enrolled in the present study. The patients' ages ranged from 25 to 72 years (mean age, 52.6 years). On EUS, all tumors were originating from muscularis propria and hypoechoic. Ten tumors have the extraluminal growth patterns and 4 tumors have the intraluminal growth patterns. Marginal halos were observed in 7 lesions. No cystic change and calcification were found inside the lesions. Complete endoscopic resection was performed in all the patients with no complications occurring in any patients. No recurrence or metastases was found in all patients during the follow-up period.Gastric schwannoma has some characteristics on EUS, but it is difficult to differentiate gastric schwannoma from gastrointestinal stromal tumor. Endoscopic resection is an effective and safe treatment for gastric schwannoma with an excellent follow-up outcome.

    Surgical management of intraconal pathology represents the next frontier in endoscopic endonasal surgery. Despite this, the medial intraconal space remains a relatively unexplored region, secondary to its variable and technically demanding anatomy. The purpose of this study is to define the neurovascular structures in this region and introduce a compartmentalized approach to enhance surgical planning. This study was an institutional review board (IRB)-exempt endoscopic anatomic study in 10 cadaveric orbits. After dissection of the medial intraconal space, the pattern and trajectory of the oculomotor nerve and ophthalmic arterial arborizations were analyzed. The position of all vessels as well as the length of the oculomotor trunk and branches relative to the sphenoid face were calculated. A mean of 1.5 arterial branches were identified (n = 15; range, 1-4) at a mean of 8.8 mm from the sphenoid face (range, 4-15 mm). The majority of the arteries (n = 7) inserted adjacent to the midline of medial rectus. The oculomotor nerve inserted at the level of the sphenoid face and arborized with a large proximal trunk 5.5 ± 1.1 mm in length and multiple branches extending 13.2 ± 2.7 mm from the sphenoid face. The most anterior nerve and vascular pedicle were identified at 17.0 and 15.0 mm from the sphenoid face, respectively. The neurovascular supply to the medial rectus muscle describes a varied but predictable pattern. This data allows the compartmentalization of the medial intraconal space into 3 zones relative to the neurovascular supply. These zones inform the complexity of the dissection and provide a guideline for safe medial rectus retraction relative to the fixed landmark of the sphenoid face. © 2014 ARS-AAOA, LLC.

    To facilitate endolumenal and natural orifice procedures, this study evaluated a novel technique using external and endoscopically placed magnets to create suture-free gastroenteral anastomoses. Seven anesthetized adult swine underwent endoscopic placement of magnets into the small bowel and stomach. Using external magnets, the endoscopically placed internal magnets were brought into opposition under endoscopic view. After 1-2 weeks, the pigs were killed and analyzed. At laparotomy and under sterile conditions, peritoneal cultures were obtained. The anastomoses were evaluated endoscopically and tested using an air insufflation test. Finally, the anastomoses were resected and evaluated microscopically. The average operative time for endoscopic placement of the magnets was 34.3 +/- 14.8 min. Successful placement and creation of anastomoses occurred in six of the pigs. One pig did not form an anastomosis because the magnets were too large to pass through the pylorus at the time of attempted magnet placement. Six swine experienced uncomplicated postoperative courses. One pig's postoperative course involved constipation for several days, requiring additional fluids and fiber supplementation. The findings at endoscopy showed that the magnets were adhered to the anastomosis, which were easily freed, or within the stomach. The air insufflation test results were negative for all the pigs. At laparotomy, there was no evidence of infection, abscess, or leak, but two peritoneal culture results were positive with scant growth of Staphylococcus aureus and coagulase-negative staphylococcus, presumably contaminants. Microscopically, the anastomoses illustrated granulation and fibrous connective tissue without evidence of infection or leak. Endoscopically placed magnets with external magnet guidance is a feasible and novel approach to creating patent gastroenteral anastomoses without abdominal incisions or sutures.

    The aim of this prospective, randomized, controlled, double-blind clinical trial was to compare the outcomes, including knee strength, balance, coordination, proprioception and response time, of Nintendo Wii Fit with those of conventional rehabilitation on the subjects with anterior cruciate ligament reconstruction. Thirty volunteer subjects were enrolled in either Wii Fit (n = 15; mean age, 29 ± 7 years) or conventional rehabilitation (n = 15; mean age, 29 ± 6 years) programmes from the first week up to 12th weeks of the operation. Endoscopic reconstruction of a completely ruptured ACL was performed by using graft harvested from hamstrings. Each subject underwent an individual therapeutic programme. Functional examinations included the measurements of the balance using modified star excursion balance test, coordination, proprioception and response time using functional squat system and strength of flexor and extensor muscles of the involved and uninvolved leg using an isokinetic machine. There was no significant difference between Wii Fit and conventional group in terms of isokinetic knee strength at 12th week, and dynamic balance, and functional squat tests including coordination, proprioception and response time at first, 8th and 12th weeks of the rehabilitation. Two different 12-week-physiotherapy programmes following ACL reconstruction have the same affect on muscle strength, dynamic balance and functional performance values in both groups. We considered that the practice of Wii Fit activities like conventional rehabilitation could also address physical therapy goals, which included improving visual-perceptual processing, coordination, proprioception and functional mobility.

  7. Endoscopic suture fixation is associated with reduced migration of esophageal fully covered self-expandable metal stents (FCSEMS).

    Esophageal fully covered self-expandable metal stents (FCSEMS) are indicated for the management of benign and malignant conditions of the esophagus including perforations, leaks, and strictures. FCSEMS are resistant to tissue ingrowth and are removable; however, stent migration occurs in 30-55% of cases. Endoscopic suture fixation of FCSEMS has been utilized to decrease the risk of stent migration though data supporting this practice remain limited. The primary aim of this study was to compare clinical outcomes and migration rate of patients who underwent placement of esophageal FCSEMS with and without endoscopic suture fixation. Our single-center, retrospective, cohort study includes patients who underwent esophageal FCSEMS placement with and without endoscopic suture fixation between January 1, 2012, and November 11, 2015. Baseline patient characteristics, procedural details, and clinical outcomes were abstracted. Logistic regression was performed to identify clinical and technical factors associated with outcomes and stent migration. A total of 51 patients underwent 62 FCSEMS placements, including 21 procedures with endoscopic suture fixation and 41 without. Suture fixation was associated with reduced risk of stent migration (OR 0.13, 95% CI 0.03-0.47). Prior stent migration was associated with significantly higher risk of subsequent migration (OR 6.4, 95% CI 1.6-26.0). Stent migration was associated with lower likelihood of clinical success (OR 0.21, 95% CI 0.06-0.69). There was a trend toward higher clinical success among patients undergoing suture fixation (85.7 vs. 60.9%, p = 0.07). Endoscopic suture fixation of FCSEMS was associated with a reduced stent migration rate. Appropriate patient selection for suture fixation of FCSEMS may lead to reduced migration in high-risk patients.

    We describe a simplified method to detect anterior lenticonus. Three eyes of 2 patients with anterior lenticonus, plus 16 eyes from 16 healthy controls underwent Scheimpflug imaging of their anterior segment with Pentacam. The anterior capsule apex angle was manually identified and automatically measured by AutoCAD. The mean angle was 173.06° (SD: 1.91) in healthy subjects, and 158.33° (SD: 3.05) in anterior lenticonus eyes. The angle obtained from patients was more than 3 SD steeper than those from healthy subjects. The apical angle calculation method seems to discriminate well between normal eyes and eyes suspected of having anterior lenticonus. Copyright © 2013 Sociedad Española de Oftalmología.

    2015-01-01

    Full Text Available This study evaluates the safety and effectiveness of computed tomography- (CT- assisted endoscopic surgery in the treatment of infectious spondylodiscitis of the thoracic and upper lumbar spine in immunocompromised patients. From October 2006 to March 2014, a total of 41 patients with infectious spondylodiscitis underwent percutaneous endoscopic surgery under local anesthesia, and 13 lesions from 13 patients on the thoracic or upper lumbar spine were selected for evaluation. A CT-guided catheter was placed before percutaneous endoscopic surgery as a guide to avoid injury to visceral organs, major vessels, and the spinal cord. All 13 patients had quick pain relief after endoscopic surgery without complications. The bacterial culture rate was 77%. Inflammatory parameters returned to normal after adequate antibiotic treatment. Postoperative radiographs showed no significant kyphotic deformity when compared with preoperative films. As of the last follow-up visit, no recurrent infections were noted. Traditional transthoracic or diaphragmatic surgery with or without posterior instrumentation is associated with high rates of morbidity and mortality, especially in elderly patients, patients with multiple comorbidities, or immunocompromised patients. Percutaneous endoscopic surgery assisted by a CT-guided catheter provides a safe and effective alternative treatment for infectious spondylodiscitis of the thoracic and upper lumbar spine.

    The safety and efficacy of craniotomy, endoscopic surgery, and stereotactic aspiration for surgical evacuation of spontaneous supratentorial lobar intracerebral hemorrhage (ICH) is yet uncertain. The present study analyzed the clinical and radiographic data from 99 patients with spontaneous supratentorial lobar ICH, retrospectively, to address this issue. Patients who underwent craniotomy, endoscopy surgery, or stereotactic aspiration were assigned to the craniotomy group (n = 31), endoscopy surgery group (n = 32), or stereotactic aspiration group (n = 36), respectively. The characteristics of all the enrolled patients at the time of admission were assimilated. Also, the therapeutic effects of the three surgical procedures were evaluated based on short-term outcomes within 30 days and long-term outcomes at 6 months after the ictus. The results showed that stereotactic aspiration and endoscopic surgery were associated with a superior clinical therapeutic effect in both short-term and long-term outcomes than craniotomy for the treatment of spontaneous supratentorial lobar ICH. Notably, severely affected patients with hematoma volume > 60 mL or Glasgow Coma Scale score 4-8 may benefit more from endoscopic surgery than the two other surgical procedures. The current findings demonstrate that both stereotactic aspiration and endoscopic surgery possess an apparent advantage over craniotomy for the evacuation of spontaneous supratentorial lobar ICH. The endoscopic surgery might be more safe and effective with higher evacuation rate, better functional neurological outcomes, and lower complication and mortality rates.

    Lateral spreading tumors (LST) are relatively large flat lesions with diameters exceeding 10 mm in length. Endoscopic mucosal resection (EMR) is a commonly used technique for removing LST. We aimed to evaluate the risk factors for incomplete resection and complications of EMR for LST. Between January 2004 and December 2010, 497 patients who underwent EMR for LST were retrospectively reviewed. Risk factors for endoscopic and histopathological complete resection, complications, and clinical outcomes were investigated. Risks for incomplete resection by piecemeal resection and en bloc resection of a lesion ≥ 30 mm were higher than for en bloc resection of a lesion LST ≥ 30 mm, hospitalize patients for 12 h and note risk for incomplete resection. (iii) Following en bloc resection for LST<30 mm, hospitalize the patient for 12 h and expect complete resection. © 2012 The Authors.

    There are only a few cases found in literature regarding air embolism in endoscopic procedures, especially in connection to endoscopic retrograde cholangiopancreatography (ERCP). We are presenting a case of a 56-year-old female patient who suffered from non-Hodgkin lymphoma located in her right groin. She was also diagnosed with choledocholithiasis and underwent ERCP to remove the gallstones. Immediately after the procedure she went into sudden cardiac arrest and subsequently died, despite all of our efforts. We reviewed literature in order to identify possible causes of death because fatal outcome following an uneventful and successful procedure was not expected. It is important to bear in mind all possible complications of ERCP. Our focus during the literature search was on air embolism.

  14. Towards automated visual flexible endoscope navigation.

    2013-10-01

    The design of flexible endoscopes has not changed significantly in the past 50 years. A trend is observed towards a wider application of flexible endoscopes with an increasing role in complex intraluminal therapeutic procedures. The nonintuitive and nonergonomical steering mechanism now forms a barrier in the extension of flexible endoscope applications. Automating the navigation of endoscopes could be a solution for this problem. This paper summarizes the current state of the art in image-based navigation algorithms. The objectives are to find the most promising navigation system(s) to date and to indicate fields for further research. A systematic literature search was performed using three general search terms in two medical-technological literature databases. Papers were included according to the inclusion criteria. A total of 135 papers were analyzed. Ultimately, 26 were included. Navigation often is based on visual information, which means steering the endoscope using the images that the endoscope produces. Two main techniques are described: lumen centralization and visual odometry. Although the research results are promising, no successful, commercially available automated flexible endoscopy system exists to date. Automated systems that employ conventional flexible endoscopes show the most promising prospects in terms of cost and applicability. To produce such a system, the research focus should lie on finding low-cost mechatronics and technologically robust steering algorithms. Additional functionality and increased efficiency can be obtained through software development. The first priority is to find real-time, robust steering algorithms. These algorithms need to handle bubbles, motion blur, and other image artifacts without disrupting the steering process.

    Dubreuil, J; Trevelo, A

    1990-01-01

    Although the anterior guidance in complete dentures is not really a guide, the arrangement of the anterior maxillary and mandibular prosthetic teeth, defines a propulsive line called the virtual anterior guidance, a part from the cinematic criterias. The influence of this guide on cuspal movement is superior, in all mandibular points, to the influence of the condylar pathway. If this line is not respected, the practitioner may have to do excessive grindings during occlusal adjustments.

    2011-03-01

    Operative treatment of prepatellar bursitis is indicated in intractable bursitis. The most common complication of surgical treatment for prepatellar bursitis is skin problems. For traumatic prepatellar bursitis, we propose a protocol of outpatient endoscopic surgery under local anaesthesia. From September 1996 to February 2001, 60 cases of failed nonoperative treatment for prepatellar bursitis were included. The average age was 33.5 ± 11.1 years (range 21-55). The average operation duration was 18 minutes. Two to three mini-arthroscopic portals were used in our series. No sutures or a simple suture was needed for the portals after operation. After follow-up for an average of 36.3 months, all patients are were symptom-free and had regained knee function. None of the population had local tenderness or hypo-aesthesia around their wound. Their radiographic and sonographic examinations showed no recurrence of bursitis. Outpatient arthroscopic bursectomy under local anaesthesia is an effective procedure for the treatment of post-traumatic prepatellar bursitis after failed conservative treatments. Both the cosmetic results and functional results were satisfactory.

  18. Training in Endoscopy: Endoscopic Ultrasound.

    Science.gov (United States)

    Cho, Chang Min

    2017-07-01

    Endoscopic ultrasound (EUS) has been recently established as an indispensable modality for the diagnosis and management of pancreatobiliary and gastrointestinal (GI) disorders. EUS proficiency requires both cognitive and technical abilities, including an understanding of the appropriate indications, the performance of appropriate evaluations before and after the procedure, and the management of procedure-related complications. An increasing demand for skills to handle a growing range of interventional EUS procedures and a continual shortage of EUS training programs are two major obstacles for EUS training. Acquiring the skills necessary to comprehend and conduct EUS often requires training beyond the scope of a standard GI fellowship program. In addition to traditional formal EUS training and preceptorships, regular short-term intensive EUS training programs that provide training at various levels may help EUS practitioners improve and maintain EUS-related knowledges and skills. Theoretical knowledge can be acquired from lectures, textbooks, atlases, slides, videotapes, digital video discs, interactive compact discs, and websites. Informal EUS training is generally based on 1- or 2-day intensive seminars, including didactic lectures, skills demonstrated by expert practitioners through live video-streaming of procedures, and hands-on learning using animal or phantom models.

    2015-05-01

    To clarify whether or not use of an endoscopic biliary stenting (EBS) is superior to endoscopic nasobiliary drainage (ENBD) in cases of acute cholangitis due to choledocholithiasis. Of 447 patients with choledocholithiasis who were treated in the Department of Gastroenterology, Fukuoka University Chikushi Hospital between January 1994 and September 2006, the subjects were 99 moderate acute cholangitis patients who underwent endoscopic drainage as initial treatment. Clinical efficacy, complications and patient satisfaction (meal intake rete) were investigated in the EBS group (67 patients) and the ENBD group (32 patients). There were no significant differences in the improvement in inflammation, total bilirubin, or biliary enzymes between the EBS and ENBD groups. Catheter occlusion was seen in three patients (4%) in the EBS group, and the catheter was self-extracted by three patients (10%) in the ENBD group. In moderate acute cholangitis due to choledocholithisis, the treatment efficacy and safety of EBS are equal to those of ENBD, and EBS appears to be a better choice in elderly patients in particular.

    The present invention provides a method for producing an anterior cruciate ligament ex vivo. The method comprises seeding pluripotent stem cells in a three dimensional matrix, anchoring the seeded matrix by attachment to two anchors, and culturing the cells within the matrix under conditions appropriate for cell growth and regeneration, while subjecting the matrix to one or more mechanical forces via movement of one or both of the attached anchors. Bone marrow stromal cells are preferably used as the pluripotent cells in the method. Suitable matrix materials are materials to which cells can adhere, such as a gel made from collagen type I. Suitable anchor materials are materials to which the matrix can attach, such as Goinopra coral and also demineralized bone. Optimally, the mechanical forces to which the matrix is subjected mimic mechanical stimuli experienced by an anterior cruciate ligament in vivo. This is accomplished by delivering the appropriate combination of tension, compression, torsion, and shear, to the matrix. The bioengineered ligament which is produced by this method is characterized by a cellular orientation and/or matrix crimp pattern in the direction of the applied mechanical forces, and also by the production of collagen type I, collagen type III, and fibronectin proteins along the axis of mechanical load produced by the mechanical forces. Optimally, the ligament produced has fiber bundles which are arranged into a helical organization. The method for producing an anterior cruciate ligament can be adapted to produce a wide range of tissue types ex vivo by adapting the anchor size and attachment sites to reflect the size of the specific type of tissue to be produced, and also adapting the specific combination of forces applied, to mimic the mechanical stimuli experienced in vivo by the specific type of tissue to be produced. The methods of the present invention can be further modified to incorporate other stimuli experienced in vivo by the

    Solitary rectal ulcer syndrome (SRUS) is often resistant to medical and surgical treatment. This study assessed the effect of biofeedback in decreasing the symptoms and the healing of endoscopic signs in SRUS patients. Before starting the treatment, endoscopy and colorectal manometry was performed to evaluate dyssynergic defecation. Patients were followed every four weeks, and during each visit their response to treatment was evaluated regarding to manometry pattern. After at least 50% improvement in manometry parameters, recipients underwent rectosigmoidoscopy. Endoscopic response to biofeedback treatment and clinical symptoms were investigated. Duration of symptoms was 43.11±36.42 months in responder and 63.9 ± 45.74 months in non-responder group (P=0.22). There were more ulcers in non-responder group than responder group (1.50 ±0.71 versus 1.33±- 0.71 before and 1.30 ± 0.95 versus 0.67 ±0.50 after biofeedback), although the difference was not significant (P=0.604, 0.10 respectively). The most prevalent symptoms were constipation (79%), rectal bleeding (68%) and anorectal pain (53%). The most notable improvement in symptoms after biofeedback occured in abdominal pain and incomplete evacuation, and the least was seen in mucosal discharge and toilet waiting as shown in the bar chart. Endoscopic cure was observed in 4 of 10 patients of the non-responder group while 8 patients in responder group experienced endoscopic improvement. It seems that biofeedback has significant effect for pathophysiologic symptoms such as incomplete evacuation and obstructive defecation. Improvement of clinical symptoms does not mean endoscopic cure; so to demonstrate remission the patients have to go under rectosigmoidoscopy.

    Transforaminal endoscopic treatment has been reported to be an effective treatment option in patients with lumbar disc herniation. However, it is rarely performed for spinal stenosis because of the limitation of endoscopic working mobility due to the exiting nerve root and foraminous bony structure. The objective of the present study was to describe a novel transforaminal endoscopic decompression technique for spinal stenosis and report the clinical results. From October 2015 to October 2016, 30 consecutive cases were diagnosed as lateral recess stenosis in our institution and underwent transforaminal endoscopic decompression. The visual analog scales(VAS) of back and leg pain and the Oswestry disability index were measured preoperatively and at the follow-up RESULTS: The mean±standard deviation value of the preoperative VAS score for leg pain was 7.6±1.17. The score improved to 2.2±1.11 at 1 week postoperatively, 1.73±0.96 at 4 weeks postoperatively, and 1.63±0.95 at 26 weeks postoperatively (Pvalue of the preoperative ODI was 65.69±14.22. The score improved to 24.29±11.89 at 1 week postoperatively, 21.25±9.25 at 4 weeks postoperatively, and 15.62±10.49 at 26 weeks postoperatively (P<0.01). There were no patients with postoperative infection, dural tear, delayed neurological deterioration, or conversion to open surgery. Transforaminal endoscopic decompression under the local anesthesia could be an effective treatment method for the selected group of patients with spinal stenosis. Copyright © 2018 Elsevier Inc.

    Adenoid hypertrophy may play a role in velopharyngeal closure especially in patients with palatal abnormality; adenoidectomy may lead to velopharyngeal insufficiency and hyper nasal speech. Patients with cleft palate even after repair should not undergo adenoidectomy unless absolutely needed, and in such situations, conservative or partial adenoidectomy is performed to avoid the occurrence of velopharyngeal insufficiency. Trans-oral endoscopic adenoidectomy enables the surgeon to inspect the velopharyngeal valve during the procedure. The aim of this study was to assess the effect of transoral endoscopic partial adenoidectomy on the speech of children with repaired cleft palate. Twenty children with repaired cleft palate underwent transoral endoscopic partial adenoidectomy to relieve their airway obstruction. The procedure was completely visualized with the use of a 70° 4mm nasal endoscope; the upper part of the adenoid was removed using adenoid curette and St. Claire Thompson forceps, while the lower part was retained to maintain the velopharyngeal competence. Preoperative and postoperative evaluation of speech was performed, subjectively by auditory perceptual assessment, and objectively by nasometric assessment. Speech was not adversely affected after surgery. The difference between preoperative and postoperative auditory perceptual assessment and nasalance scores for nasal and oral sentences was insignificant (p=0.231, 0.442, 0.118 respectively). Transoral endoscopic partial adenoidectomy is a safe method; it does not worsen the speech of repaired cleft palate patients. It enables the surgeon to strictly inspect the velopharyngeal valve during the procedure with better determination of the adenoidal part that may contribute in velopharyngeal closure.

    GRNB® is a non-radiating power tool that allows the evaluation of the anterior tibial translation. The pressure exerted by the system against the patella and the body mass index (BMI) could affect the anterior tibial translation when we repeat the measurements in healthy knees. We retrospectively evaluated the measurements of anterior knee laxity in healthy knees carried out by the GNRB® in 69 consecutive patients who underwent anterior cruciate ligament (ACL) repair in the contralateral knee. Two measurements were carried out, the initial measurements (M1), and then repeated at a mean of seven months (M2) (4.9 to 13months). There were 38 women and 31 men with an average age of 31years. In healthy knees, the Mean average anterior translation was 5.4±4mm with an average patellar force of 35.8 at time M1. The average anterior translation was 4.9±4mm with an average patellar force of 47 at time M2. There was a significant difference between the measurements M1 and M2 (P<0.03). The tightening force was significantly different between the two sets of measurements (P<10-7). There was a negative correlation between the pressure applied on the patella and anterior knee laxity (P<0.01). The pressure force exerted on the patella during GNRB® affects the measurement of anterior laxity in healthy knees. This raises the problem of the reproducibility of the measurements during repeated examinations at different times. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available Abstract Objective: The present study investigated effect of using pump on postoperative pleural effusion in patients who underwent coronary artery bypass grafting. Methods: A total of 256 patients who underwent isolated coronary artery bypass grafting surgery in the Cardiovascular Surgery clinic were enrolled in the study. Jostra-Cobe (Model 043213 105, VLC 865, Sweden heart-lung machine was used in on-pump coronary artery bypass grafting. Off-pump coronary artery bypass grafting was performed using Octopus and Starfish. Proximal anastomoses to the aorta in both on-pump and off-pump techniques were performed by side clamps. The patients were discharged from the hospital between postoperative day 6 and day 11. Results: The incidence of postoperative right pleural effusion and bilateral pleural effusion was found to be higher as a count in Group 1 (on-pump as compared to Group 2 (off-pump. But the difference was not statistically significant [P>0.05 for right pleural effusion (P=0.893, P>0.05 for bilateral pleural effusion (P=0.780]. Left pleural effusion was encountered to be lower in Group 2 (off-pump. The difference was found to be statistically significant (P<0.05, P=0.006. Conclusion: Under the light of these results, it can be said that left pleural effusion is less prevalent in the patients that underwent off-pump coronary artery bypass grafting when compared to the patients that underwent on-pump coronary artery bypass grafting.

    Full Text Available BACKGROUND: Clinical experiences of adults who underwent surgery for esophageal atresia at birth is limited. There is some evidence that suggests considerable long-term morbidity, partly because of dysphagia, which has been reported in up to 85% of adult patients who undergo surgery for esophageal atresia. The authors hypothesized that dysphagia in this population is caused by dysmotility and/or anatomical anomalies.

    2008-03-01

    Recently, the field of gastrointestinal endoscopy is developing rapidly. Once limited to the gastroinstestinal lumen, the endoscopic technology is now breaking the barriers and extending its boundary to peritoneal and pleural space. In 2004, Dr. Kalloo, a gastroenterologist, observed intraperitoneal organs of a pig using a conventional endoscope through the stomach wall. Since then, new endoscopic technique of intraperitoneal intervention with transluminal approach named the Natural Orifice Transluminal Endoscopic Surgery or NOTES has been introduced. NOTES reaches the target organ by inserting the endoscope through a natural orifice (e.g. mouth, anus, vagina, urethra) and entering the peritoneal lumen by means of making an incision on the luminal wall. After a series of successful experiences in animal studies, NOTES are now being tried on human subjects. There are still many obstacles to overcome, but bright future for this new technology is expected because of its proposed advantages of less pain, lower complication rate, short recovery time, and scarless access. In this review, we plan to learn about NOTES.

    Oral and maxillofacial surgery is entering a new era. Surgeons can use the latest technological advances in equipment in an attempt to improve patient outcomes. Minimally invasive surgery with the use of the endoscope has improved in recent years because of technological advancements in optics and associated instrumentation. Trauma, orthognathic, sialoendoscopy, and temporomandibular joint surgery are commonly performed with the assistance of the endoscope. From an educational standpoint, surgical anatomy and various other principles can easily be taught to trainees with the assistance of the endoscope. The operating surgeon can visualize an area via the endoscope, and instruct regarding the surgical maneuvers on the monitor, without obstructions to view. This technique also allows others in and out of the room to view the image. Endoscopically assisted surgery is gaining popularity and is becoming a tool frequently used by surgeons to assist in and simplify some of the more difficult techniques that often require more extensive surgical exposure for visualization.

    Nasal encephalocele may presents as a nasal mass, its treatment is surgical and it should be done early in life. When removal is indicated, there are multiple surgical approaches; including lateral rhinotomy, a transnasal approach and a coronal flap approach. However, the treatment of a basal intranasal encephalocele using transnasal endoscopic approach could obviates the possible morbidity associated with other approaches. The aim of this study was to evaluate the efficacy of endoscopic removal of intranasal encephalocele, also to document the role of anesthetist in the operative and postoperative periods. Nine cases with nasal encephalocele were included in this study; CT and/or MRI were used in their examination. The lesions were removed via transnasal endoscopic approach. Preoperative evaluation, intervention and postoperative follow-up were presented with discussion of anesthesia used for those children. The lesions of all patients were removed successfully with no recurrence through the follow-up period of at least 21 months. No cases showed morbidity or mortality intra- or post-operatively. Endoscopic excision of intranasal encephalocele is an effective method with high success rate. Anesthetist plays an important role in the operative and postoperative period, even during the endoscopic follow up; sedation of the children is usually needed.

    Full Text Available Introduction: There is a steady increase in the number of elderly patients with severe cardiovascular diseases who require a surgical procedure to recover some quality of life that allows them a socially meaningful existence, despite the risks.Objectives: To analyze the behavior of elderly patients who underwent cardiac surgery with cardiopulmonary bypass.Method: A descriptive, retrospective, cross-sectional study was conducted with patients over 65 years of age who underwent surgery at the Cardiocentro Ernesto Che Guevara, in Santa Clara, from January 2013 to March 2014.Results: In the study, 73.1% of patients were men; and there was a predominance of subjects between 65 and 70 years of age, accounting for 67.3%. Coronary artery bypass graft was the most prevalent type of surgery and had the longest cardiopulmonary bypass times. Hypertension was present in 98.1% of patients. The most frequent postoperative complications were renal dysfunction and severe low cardiac output, with 44.2% and 34.6% respectively.Conclusions: There was a predominance of men, the age group of 65 to 70 years, hypertension, and patients who underwent coronary artery bypass graft with prolonged cardiopulmonary bypass. Renal dysfunction was the most frequent complication.

    Full Text Available BACKGROUND: Atherosclerosis is the main cause of peripheral artery occlusive disease (PAOD of the lower limbs. Patients with PAOD often also have obstructive atherosclerosis in other arterial sites, mainly the coronary arteries. This means that patients who undergo infrainguinal bypass to treat critical ischemia have a higher risk of AMI. There are, however, few reports in the literature that have assessed this risk properly. OBJECTIVE: The aim of this study was to determine the incidence of acute myocardial infarction in patients who underwent infrainguinal bypass to treat critical ischemia of the lower limbs caused by PAOD. MATERIAL AND METHODS: A total of 64 patients who underwent 82 infrainguinal bypass operations, from February 2011 to July 2012 were studied. All patients had electrocardiograms and troponin I blood assays during the postoperative period (within 72 hours. RESULTS: There were abnormal ECG findings and elevated blood troponin I levels suggestive of AMI in five (6% of the 82 operations performed. All five had conventional surgery. The incidence of AMI as a proportion of the 52 conventional surgery cases was 9.6%. Two patients died. CONCLUSION: There was a 6% AMI incidence among patients who underwent infrainguinal bypass due to PAOD. Considering only cases operated using conventional surgery, the incidence of AMI was 9.6%.

    : Totally endoscopic coronary artery bypass grafting (TECAB) requires telemanipulation technologies because attempts using conventional thoracoscopic instrumentation have completely failed. These complex operations require individual and team learning curves and necessitate a stepwise approach. The aim of this study is to assess risk adjusted outcome in robotically assisted coronary artery bypass grafting (CABG) after the first 6 years of application. : From 2001 to 2007, 177 CABG procedures were performed using the da Vinci system. A low risk patient population [age 59 (31-76) years, EuroSCORE 1 (0-7)] was treated. The following procedures were carried out: endoscopic internal mammary artery takedown in minimally invasive direct coronary artery bypass, Off-pump coronary artery bypass, and CABG (n = 26); robotic suturing of left internal mammary artery to left anterior descending artery anastomoses through sternotomy (n = 32); TECAB on the arrested heart (n = 108); TECAB on the beating heart (n = 11). : There was no hospital mortality, and cumulative risk adjusted mortality plots showed that 2.76 predicted events did not occur. Given 177 event free procedures Clopper Pearson estimations revealed a 95% confidence interval between 0.0% and 2.3% for perioperative mortality. : Introduction of robotic TECAB grafting appears to meet current CABG safety standards. Initial application in low risk patients and a stepwise approach towards completely endoscopic versions of the operation are worthwhile. Despite a high grade of innovation and despite learning curves, perioperative mortality may be lower than predicted.

    Full Text Available Abstract Background Osteochondroma is the most common benign bone tumor in the scapula. This condition might lead to snapping scapula syndrome, which is characterized by painful, audible, and/or palpable abnormal scapulothoracic motion. In the present case, this syndrome was successfully treated by use of endoscopically assisted resection of the osteochondroma. Case presentation A 41-year-old man had a tolerable pain in his scapular region over a 10 years' period. The pain developed gradually with shoulder motion, in particular with golf swing since he was aiming a professional golf player career. On physical examination, "clunking" was noted once from 90 degrees of abduction to 180 degrees of shoulder motion. A trans-scapular roentgenogram and computed tomography images revealed an osteochondroma located at the anterior and inferior aspect of the scapula. Removal of the tumor was performed by the use of endoscopically assisted resection. One portal was made at the lateral border of the scapula to introduce a 2.7-mm-diameter, 30 degrees Hopkins telescope. The tumor was resected in a piece-by-piece manner by the use of graspers through the same portal. Immediately after the operation pain relief was obtained, and the "clunking" disappeared. CT images showed complete tumor resection. The patient could start playing golf one week after the surgery. Conclusion Endoscopically assisted resection of osteochondroma of the scapula provides a feasible technique to treat snapping scapula syndrome and obtain early functional recovery with a short hospital stay and cosmetic advantage.

    To investigate prevalence and risk factors of pelvic organ prolapse in women underwent routine gynecologic health care in Peking Union Medical College Hospital (PUMCH). From Jan. 2008 to Aug. 2009, 972 women underwent gynecological health care in PUMCH were enrolled in this study. Questionnaires and pelvic examinations were given. The pelvic organ prolapse quantitive examination (POP-Q) system was used as the assessment tool. (1) Among all participants, the mean ages were (42 ± 10) years (range 22 to 78 years), the mean height were (162 ± 5) cm (range 142 to 180 cm), and the mean weight were (59 ± 8) kg (range 42 to 91 kg). 83.8% (815/972) of women were multipara. The mean total vaginal length (TVL) of 972 women was 8.20 cm. No women met the standard of pelvic organ prolapse, while 35.5% (345/972) of women presented mild posterior vaginal descent and 96.7% (940/972) presented mild anterior vaginal descent, all of them were asymptomatic. (2) The length of genital hiatus (gh), TVL and C, D proximal to the hymen in nullipara were (2.26 ± 0.32), (8.08 ± 0.30), (-7.08 ± 0.24) and (-8.08 ± 0.30) cm, which were significantly less than (2.33 ± 0.39), (8.22 ± 0.35), (-7.14 ± 0.28) and (-8.22 ± 0.35) cm in multipara (P 0.05). However, those in women at group of 22 - 34 years and 35 - 49 years showed statistical difference when compared with women at group of more than 50 years (P < 0.05). When compared with women at group of 22 - 34 years, the incidence of posterior and anterior vaginal wall protrusion were increased (OR = 1.713, 3.765). (4) Menopause status was associated with severities of all kinds of descent (P < 0.05) and presence of posterior vaginal protrusion (OR = 3.354). Mild anterior and posterior vaginal descent by POP-Q were common among women in China. The risk of anterior vaginal descent is relatively higher than posterior vaginal descent. However, most of the women with descent are asymptomatic and need no treatment. The most important factors

    OBJECTIVE The endoscopic third ventriculostomy (ETV) is an established and effective treatment for obstructive hydrocephalus. In its most common application, surgeons plan their entry point and the endoscope trajectory for the procedure based on anatomical landmarks, then control the endoscope freehand. Recent studies report an incidence of neural injuries as high as 16.6% of all ETVs performed in North America. The authors have introduced the ROSA system to their ETV procedure to stereotactically optimize endoscope trajectories, to reduce risk of traction on neural structures by the endoscope, and to provide a stable mechanical holder of the endoscope. Here, they present their series in which the ROSA system was used for ETVs. METHODS At the authors' institution, they performed ETVs with the ROSA system in 9 consecutive patients within an 8-month period. Patients had to have a favorable expected response to ETV (ETV Success Score ≥ 70) with no additional endoscopic procedures (e.g., choroid plexus cauterization, septum pellucidum fenestration). The modality of image registration (CT, MRI, surface mapping, or bone fiducials) was dependent on the case. RESULTS Nine pediatric patients with an age range of 1.5 to 16 years, 4 girls and 5 boys, with ETV Success Scores ranging from 70 to 90, underwent successful ETV surgery with the ROSA system within an 8-month period. Their intracranial pathologies included tectal tumors (n = 3), communicating hydrocephalus from hemorrhage or meningeal disease (n = 2), congenital aqueductal stenosis (n = 1), compressive porencephalic cyst (n = 1), Chiari I malformation (n = 1), and pineal region mass (n = 1). Robotic assistance was limited to the ventricular access in the first 2 procedures, but was used for the entirety of the procedure for the following 7 cases. Four of these cases were combined with another procedural objective (3 stereotactic tectal mass biopsies, 1 Chiari decompression). A learning curve was observed with each

    To apply the laparoscopic and endoscopic cooperative surgery concept, we investigated whether endoscopic cholecystectomy could be performed more safely and rapidly via only 1 port or not. Two dogs (11 and 13-mo-old female Beagle) were used in this study. Only 1 blunt port was created, and a flexible endoscope with a tip attachment was inserted between the fundus of gallbladder and liver. After local injection of saline to the gallbladder bed, resection of the gallbladder bed from the liver was performed. After complete resection of the gallbladder bed, the gallbladder was pulled up to resect its neck using the Ring-shaped thread technique. The neck of the gallbladder was cut using scissor forceps. Resected gallbladder was retrieved using endoscopic net forceps via a port. The operation times from general anesthetizing with sevoflurane to finishing the closure of the blunt port site were about 50 min and 60 min respectively. The resection times of gallbladder bed were about 15 min and 13 min respectively without liver injury and bleeding at all. Feed were given just after next day of operation, and they had a good appetite. Two dogs are in good health now and no complications for 1 mo after endoscopic cholecystectomy using only a flexible endoscope via one port. We are sure of great feasibility of endoscopic cholecystectomy via single port for human.

    Background Improved treatment and survival of patients with skull base tumors has made the assessment of quality-of-life (QoL) in this population increasingly important. This article provides a comprehensive systematic review pertaining to QoL assessment in adults undergoing anterior skull base surgery. Methods We performed a literature search using the electronic databases of Ovid Medline and Embase. Additional articles were identified through a search using the phrase anterior skull base. Further articles were sought through hand-searching relevant journals and reference lists of identified articles. Results Our search strategy identified 29 articles for inclusion in our systematic review, with considerable variation between studies in population characteristics, methodological design and quality, follow-up length, and outcome assessment. The most commonly used QoL tools were the Karnofsky Performance Status and the Anterior Skull Base Questionnaire. QoL following anterior skull base surgery appears to improve beyond preoperative levels in the months after surgery. For patients undergoing endoscopic skull base surgery, the gain in QoL appears to be greater and may manifest earlier, with no clear long-term deleterious effect on sinonasal outcomes compared with open surgery. Conclusions QoL after anterior skull base surgery in adults appears to improve within several months of surgery, but earlier and to a larger extent if the endoscopic approach is used. Given the relative paucity and heterogeneity of anterior skull base tumors, large-scale prospective multicentre studies utilizing valid and reliable multidimensional QoL tools are required. This may result in improved patient care, by understanding patients' needs better and facilitating the provision of reliable outcome data for clinical trials.

    Endoscopic ultrasound-guided transmural drainage and necrosectomy have become the standard treatment for patients with pancreatic walled-off necrosis (WON). Lumen-apposing metal stents (LAMS) have shown success in the management of pancreatic fluid collections. However, there are few data on their specific roles in management of WON. We investigated the efficacy and safety of LAMS in treatment of WON. We performed a retrospective multicenter case series of 124 patients with WON who underwent endoscopic transmural drainage by using LAMS at 17 tertiary care centers from January 2014 through May 2015. Patients underwent endoscopic ultrasound-guided cystogastrostomy or cystoenterostomy with placement of an LAMS into the WON collection. At the discretion of the endoscopist, we performed direct endoscopic necrosectomy, irrigation with hydrogen peroxide, and/or nasocystic drain placement. We performed endoscopic retrograde cholangiopancreatography with pancreatic duct stent placement when indicated. Concomitant therapies included direct endoscopic debridement (n = 78), pancreatic duct stent placement for leak (n = 19), hydrogen peroxide-assisted necrosectomy (n = 38), and nasocystic irrigation (n = 22). We collected data for a median time of 4 months (range, 1-34 months) after the LAMS placement. The primary outcomes were rates of technical success (successful placement of the LAMS), clinical success (resolution of WON, on the basis of image analysis, without need for further intervention via surgery or interventional radiology), and adverse events. The median size of the WON was 9.5 cm (range, 4-30 cm). Eight patients had 2 LAMS placed for multiport access, all with technical success (100%). Clinical success was achieved in 107 patients (86.3%) after 3 months of follow-up. Thirteen patients required a percutaneous drain, and 3 required a surgical intervention to manage their WON. The stents remained patent in 94% of patients (117 of 124) and migrated in 5.6% of

    Endoscopic sphincterotomy is an integral component of endoscopic retrograde cholangiopancreatography. Post-sphincterotomy hemorrhage is a recognized complication. First line treatment involves a variety of endoscopic techniques performed at the time of sphincterotomy. If these are not successful, transcatheter arterial embolization or open surgical vessel ligation are therapeutic considerations.

    The treatment of patients with achalasia is complex due to a considerably high recurrence rate and risk of treatment-related complications. The per-oral endoscopic myotomy (POEM) is a new endoscopic technique that combines the benefits of a minimally invasive endoscopic procedure with the efficacy of a surgical myotomy. Implementation of the POEM technique may lead to fewer complications, a lower recurrence rate and reduced costs. During the procedure, a myotomy of the circular muscle layer of the oesophagus is performed after creating a submucosal tunnel in the oesophagus. The first studies of this new technique show promising results. Experienced therapeutic endoscopists can learn to perform the POEM technique relatively easily. Further studies are needed to compare this technique with the current standard treatments and to evaluate long-term effects.

    Along with the dynamic evolution of the new field of digestive endoscopy, the need of unified and unambiguous terms for endoscopic findings arose in the second half of the 20th century. In collaboration with the OMED members, professor Zdeněk Mařatka drew up the first internationally acknowledged terminology for digestive endoscopy which was used in the full range for a period of almost 20 years. The technical progress later brought with it endoscopes which made it possible to view flat lesions, frequently overlooked until then. The classification of the surface lesions was further specified by the Paris Classification which drew from the experience of Japanese endoscopists. Thanks to the new endoscopic methods of imaging mucosa in vivo and the pit-pattern and vascular-pattern classification, we can currently estimate the biological nature of lesion with great accuracy and therefore choose the best therapeutic procedure.

    Endoscopic retrograde cholangiopancreatography (ERCP) was carried out for the first time in 1968. Five years later endoscopic sphincterotomy was performed. Since then both modalities have become established as necessary adjuncts in the diagnosis and treatment of patients with pathology in the bile duct or pancreas. The main indication is common bile duct stone, and as a consequence of this treatment fewer patients are now treated surgically. Patients with malignant bile duct obstruction can be given reasonable palliation of both jaundice and pruritus and therefore improved quality of life. Some reports indicate that endoscopic drainage may be useful for pancreatic stenosis. Complications are few, but vigilance and prompt treatment is necessary to keep morbidity at a minimum. Follow-up after several years shows that sphincterotomy is successful also in the long term. The authors discuss the present diagnostic and therapeutic situation. 31 refs., 2 tabs

    Most patients with cholangiocarcinoma (CCA) have unresectable disease. Endoscopic bile duct drainage is one of the major objectives of palliation of obstructive jaundice. Stent implantation using endoscopic retrograde cholangiography is considered to be the standard technique. Unilateral versus bilateral stenting is associated with different advantages and disadvantages; however, a standard approach is still not defined. As there are various kinds of stents, there is an ongoing discussion on which stent to use in which situation. Palliation of obstructive jaundice can be augmented through the use of photodynamic therapy (PDT). Studies have shown a prolonged survival for the combinations of PDT and different stent applications as well as combinations of PDT and additional systemic chemotherapy. More well-designed studies are needed to better evaluate and standardize endoscopic treatment of unresectable CCA.

    With its inception nearly half a century ago through the pioneering work of Dandy, McLean, and Smith, anterior skull base (ASB) surgery is a relatively young discipline. It became a distinct entity in 1963 when Ketcham popularized the combined transcranial transfacial approach for en bloc resection of tumors of the paranasal sinuses extending into the anterior cranial fossa. However, because these procedures resulted in major morbidities and mortalities, alternative modes of treatment were sought. Since the 1970s, the introduction and promotion of the surgical endoscope by Messerklinger, Stammberger, and Kennedy, commenced the era of endoscopic sinus surgery. Thaler and colleagues described the utility of the endoscope for ASB surgery at the turn of the century. This allowed direct visualization and safer, more accurate removal of tumors. In 2001, Casiano reported the first purely endoscopic endonasal ASB resection, a novel technique that has been adopted by major skull base centers. The success of ASB surgery can be attributed to both the development of the skull base team as well as improvements in surgical techniques, instrumentation, and visualization technology. In this article, we review the historical evolution of ASB surgery as we approach the 50th anniversary since its recognition as a distinct entity.

    Full Text Available A 74-year-old man presented with recurrent vomiting and aspiration pneumonia in the left lower lobe. He entered the intensive care unit to manage the pneumonia and septic shock. Although a percutaneous endoscopic gastrostomy tube was implanted for recurrent vomiting, vomiting and aspiration recurred frequently during admission. Subsequently, he complained of neck pain when in an upright position. A videofluoroscopic swallowing study showed compression of the esophagus by cervical osteophytes and tracheal aspiration caused by an abnormality at the laryngeal inlet. Cervical spine X-rays and computed tomography showed anterior cervical osteophytes at the C3-6 levels. Surgical decompression was scheduled, but was cancelled due to his frailty. Unfortunately, further recurrent vomiting and aspiration resulted in respiratory arrest leading to hypoxic brain damage and death. Physicians should consider cervical spine disease, such as diffuse skeletal hyperostosis as an uncommon cause of recurrent aspiration pneumonia.

    Objective. The aim of this study was to compare the differences in thyroid hormone, intelligence, attention, and quality of life (QoL) of children with obstructive sleep apnea hypopnea syndrome (OSAHS) before and after endoscopic adenoidectomy. Method. A total of 35 OSAHS children (21 males and 14 females with a mean age of 6.81 ± 1.08 years) were included in this study for analyzing the levels of thyroid hormone, intelligence, attention, and QoL. There were 22 children underwent endoscopic adenoidectomy with bilateral tonsillectomy (BT), while the other 13 children who underwent endoscopic adenoidectomy without bilateral tonsillectomy without BT. Results. Our results revealed no significant difference in serum free triiodothyronine (FT3), free thyroxine (FT4), and thyroid stimulating hormone (TSH) levels in OSAHS children before and after endoscopic adenoidectomy (all P > 0.05). However, there were significant differences in full-scale intelligence quotient (FIQ) (92.45 ± 5.88 versus 106.23 ± 7.39, P attention (98.48 ± 8.74 versus 106.87 ± 8.58, P attention, and QoL of OSAHS children may be significantly improved after endoscopic adenoidectomy.

    Percutaneous endoscopic gastrostomy (PEG) is a safe and effective endoscopic surgical procedure for enteral access and gastrointestinal decompression, and it is an excellent alternative to surgical gastrostomy. There are various clinical indications and these mainly include the need for prolonged enteral nutritional support due to complications from neurological, geriatric and oncological diseases and decompression of the gastrointestinal tract. Although safe and effective, a number of possible complications relating to the time (early or late complications) and severity (minor or major complications) may occur. To evaluate the indications and complications relating to PEG among selected patients at the digestive endoscopy service of a regional referral hospital. A retrospective study on patients who underwent PEG between May 2013 and April 2015 was conducted. The patients were identified through searching the medical records and using a standardized data form. 53 cases were analyzed. The average age was 70.47 years and 60.37% of the patients werewomen. The main indication identified was the need for enteral nutritional support, and 73.58% of these indications were derived from neurological complications, 15.09% from geriatric complications and 9.43% from oncological complications and 1.88% were due to gastrointestinal decompression. Complications occurred in 24.52% of the cases: 23.07% were major and 76.93% were minor. Regarding the time, there were eight cases of late complications and five of early complications. PEG was shown to be an effective and safe method for enteral access. The indication and complication rates were similar to those reported in the literature.

    Obstructive submandibular sialadenitis is a relatively common disease in the clinic. The present study explored the cause and strategic management of chronic obstructive sialadenitis using sialoendoscopy and surgery. From January 2005 to October 2007, 128 patients with obstructive symptoms in the submandibular gland were diagnosed using sialoendoscopy and occlusal films, and the obstructions were removed using interventional sialoendoscopy, surgery only, or combined techniques, depending on the size, shape, site, and quality of the sialolith in the duct. The shape and structure of the hilus of the submandibular gland was observed using sialoendoscopy. In the submandibular gland, the histologic features of 128 cases were identified endoscopically and radiographically. The endoscopic findings were of 3 types: sialolith in 114 (89%), mucus plug in 8 (6%), and stenosis in 6 (5%). Of 51 obstructions treated surgically, 47 were removed successfully, for a success rate of 92%. Of 63 obstructions treated using interventional sialoendoscopy, 52 were removed directly by sialoendoscopy, for a success rate of 83%. The unsuccessful cases were treated using sialoendoscopy or surgery. The obstructive symptoms were relieved in 12 of 14 patients without stones using dilation and irrigation under sialoendoscopy. Of the 114 patients with a stone, the sialoliths of 67 (59%) were located in the distal region (behind the first molar). The results showed that the more posterior the stone, the more difficult it was to remove. Three patients with treatment failure ultimately underwent resection of the gland. A basin-like structure in the hilus region was found in 86 (67%) of the 128 patients by sialoendoscopy. Finally, 5 patients were found to have a foreign body (fish bone) surrounded by a sialolith. Sialoendoscopy is a useful new technique, not to only detect the cause of obstruction in a submandibular gland, but also to treat the obstructive submandibular sialadenitis more effectively

    Full Text Available Background: Transforaminal lumbar endoscopic discectomy (TLED is a minimally invasive procedure for removing lumbar disc herniations. This technique was initially reserved for herniations in the foraminal or extraforaminal region. This study concentrated on our experience regarding the outcomes and efficacy of TLED. Materials and Methods: A total of 105 patients were included in the study. The patients were retrospectively evaluated for demographic features, lesion levels, numbers of affected levels, visual analog scores (VASs, Oswestry disability questionnaire scale scores and MacNab pain relief scores. Results: A total of 48 female and 57 male patients aged between 25 and 64 years (mean: 41.8 years underwent TLED procedures. The majority (83% of the cases were operated on at the levels of L4-5 and L5-S1. Five patients had herniations at two levels. There were significant decreases between the preoperative VAS scores collected postoperatively at 6 months (2.3 and those collected after 1-year (2.5. Two patients were referred for microdiscectomy after TLED due to unsatisfactory pain relief on the 1 st postoperative day. The overall success rate with respect to pain relief was 90.4% (95/105. Seven patients with previous histories of open discectomy at the same level reported fair pain relief after TLED. Conclusions: Transforaminal lumbar endoscopic discectomy is a safe and effective alternative to microdiscectomy that is associated with minor tissue trauma. Herniations that involved single levels and foraminal/extraforaminal localizations were associated with better responses to TLED.

    Laparoscopic and endoluminal surgical techniques have evolved and allowed improvements in the methods for treating benign and malignant gastrointestinal diseases. To date, only case reports have been reported on the application of a laparo-endoscopic approach for resecting gastric submucosal tumors (SMT). In this study, we aimed to evaluate the efficacy, safety, and oncologic outcomes of a laparo-endoscopic transgastric approach to resect tumors that would traditionally require either a laparoscopic or open surgical approach. Herein, we present the largest single institution series utilizing this technique for the resection of gastric SMT in North America. We performed a retrospective review of a prospectively collected patient database. Patients who presented for evaluation of gastric SMT were offered this surgical procedure and informed consents were obtained for participation in the study. Fourteen patients were included in this study between August/2010 and January/2013. Eight (8) patients (57.1 %) were female and the median age was 56 years (range 29-78). Of the 14 cases, 8 patients (57.1 %) underwent laparo-endoscopic resection of SMTs with transgastric extraction, 5 patients (35.7 %) had conversions to traditional laparoscopic surgery, and 1 patient (7.2 %) was abandoned intraoperatively. The median operative time for this cohort was 80 min (range 35-167). Ten patients (71.4 %) had GISTs, 3 (21.4 %) had leiomyomas, and 1 (7.1 %) had schwannoma. There were no intraoperative complications. Two patients had postoperative staple line bleeding that required repeat endoscopy. The median hospital stay was 1 day (range 1-6) and there were no postoperative mortalities. At 12-month follow-up visit, only one GIST patient (10 %) had tumor recurrence. Our experience suggests that this surgical approach is safe and efficient in the resection of gastric SMT with transgastric extraction. This study found no intraoperative complications and optimal oncologic outcomes during

    To report outcome of axillary nerve neurotisation for brachial plexus injury through the anterior deltopectoral approach. Nine men aged 20 to 52 (mean, 27.8) years with brachial plexus injury underwent axillary nerve neurotisation through the anterior deltopectoral approach. Three of the patients had complete avulsion of C5-T1 nerve roots. The remaining 6 patients had brachial plexus injury of C5-C6 nerve roots, with associated subluxation of the glenohumeral joint, atrophy of the supraspinatus, deltoid and elbow flexors. They had no active shoulder abduction, external rotation, and elbow flexion. The pectoralis major and minor were cut and/or retracted to expose the underlying infraclavicular plexus. The axillary nerve was identified with respect to the available donor nerves (long head of triceps branch, thoracodorsal nerve, and medial pectoral nerve). In addition to the axillary nerve neurotisation, each patient had a spinal accessory nerve transferred to the suprascapular nerve for better shoulder animation. Patients were followed up for 24 to 30 (mean, 26) months. In the 3 patients with C5-T1 nerve root injuries, the mean active abduction and external rotation were 63 and 20 degrees, respectively, whereas the mean abduction strength was M3 (motion against gravity). In the 6 patients with C5-C6 nerve root injuries, the mean active abduction and external rotation were 133 and 65 degrees, respectively, whereas the strength of the deltoids and triceps was M5 (normal) in all. In 4 patients with the pectoralis major cut and repaired, the muscle regained normal strength. The anterior deltopectoral approach enabled easy access to all available donor nerves for axillary nerve neurotisation and achieved good outcomes.

    1995-10-01

    Resection of the corrugator muscles has been done for years as a routine adjunct to open coronal browlifts. The new endoscopic procedure described here permits endoscopic resection of the corrugator muscles through three 5-mm hairline incisions in those patients who do not need or want a browlift. The primary benefit is that of reducing the subconscious tendency to frown that some patients exhibit whenever concentrating or conversing. Although patients typically seek plastic surgery procedures to improve how they see themselves, these patients seek a reduction in the subconscious frown to improve how others see them and react to this unattractive facial expression.

    Full Text Available Total mesorectal excision is the “golden standard” of surgical treatment for rectal cancer. Development of endoscopic technologies allowed to implement the benefits of minimally invasive surgery in early rectal cancer treatment, decrease morbidity and mortality, improve functional outcome and quality of life. Oncological safety of this method is still a subject for discussion due to lack of lymph node harvest. Endoscopic operations for early rectal cancer are being actively implemented in daily practice, but lack of experience does not allow to include this method in national clinical prac-tice guidelines.

    To explore the feasibility and safety of transtracheal assisted sublingual approach to totally endoscopic thyroidectomy by studying the anatomical approach and adjacent structures. A total of 5 embalmed adult cadavers from Chengdu Medical College were dissected layer by layer in the cervical region, pharyngeal region, and mandible region, according to transtracheal assisted sublingual approach that was verified from the anatomical approach and planes. A total of 15 embalmed adult cadavers were dissected by arterial vascular casting technique, imaging scanning technique, and thin layer cryotomy. Then the vessel and anatomical structures of thyroid surgical region were analyzed qualitatively and quantitatively. Three-dimensional visualization of larynx artery was reconstructed by Autodesk 3ds Max 2010(32). Transtracheal assisted sublingual approach for totally endoscopic thyroidectomy was simulated on 5 embalmed adult cadavers. The sublingual observed access was located in the middle of sublingual region. The geniohyoid muscle, mylohyoid seam, and submental triangle were divided in turn in the middle to reach the plane under the plastima muscles. Superficial cervical fascia, anterior body of hyoid bone, and infrahyoid muscles were passed in sequence to reach thyroid gland surgical region. The transtracheal operational access was placed from the cavitas oris propria, isthmus faucium, subepiglottic region, laryngeal pharynx, and intermediate laryngeal cavit, and then passed from the top down in order to reach pars cervicalis tracheae where a sagittal incision was made in the anterior wall of cartilagines tracheales to reach a ascertained surgical region. Transtracheal assisted sublingual approach to totally endoscopic thyroidectomy is anatomically feasible and safe and can be useful in thyroid gland surgery.

    Long-term retrospective evaluation was performed of computed tomography (CT) images and endoscopic findings after endoscopic sinus surgery for 88 cases of chronic pediatric sinusitis with nasal polyps. The objective was to determine the appropriate duration of such postoperative evaluation for children. Fifty-one patients had both sinusitis and nasal polyps (BSP group), and the surgical procedure was decided in consideration of each patient's age (for less than 10 years of age, polypectomy (n=12); for 10-13 years old, anterior ethmoidectomy plus opening of the fontanelle and nasofrontal duct (n=20); and for serious cases older than 13 years, total sinusectomy (n=19)). On the other hand, for cases of unilateral sinusitis with antrochoanal polyps (USP group), anterior ethmoidectomy plus opening of the fontanelle was performed regardless of the patient's age (n=37, 5-15 years old). The postoperative endoscopic findings indicated that the polyps had been eliminated in approximately 91% of total patients. Good postoperative findings of CT images in most patients of USP group are observed at one year after the operation like the same of the postoperative course of adult chronic sinusitis. On the other hand CT images in BSP group evaluated one year after the operation were rated as unchanged or worsened in approximately half of the patients. However, at 4 years after the operation nearly all the patients were rated as improved or better. In addition, comparison of the age at final observation and the postoperative course found a striking decrease in the proportion of unchanged and worsened patients aged 12 and above. Accordingly, it was concluded that there is difference of healing process after the operation between USP and BSP group. Postoperative evaluation of BSP group should be performed for 4 years and up to an age of at least 12 years although post-ESS following of USP group is similar to that of adult sinusitis.

    To explore the feasibility of endoscopic retrograde cholangiopancreatography (ERCP) in pregnant women with severe acute biliary pancreatitis. In total, 24 pregnant patients with severe acute biliary pancreatitis were enrolled in our study between January 2003 and January 2008. Emergency ERCP and endoscopic nasobiliary drainage (ENBD) without fluoroscopy were performed successfully in all 24 patients within 12-72 hours of admission. Once stabilized, 15 patients in late pregnancy underwent a second ERCP with fluoroscopy to remove common bile duct (CBD) stones after pregnancy termination. Nine patients in early or mid-pregnancy continued gestating and underwent endoscopic retrograde biliary drainage (ERBD) with a second ERCP without fluoroscopy, and their stents and CBD stones were removed during a third ERCP with fluoroscopy 1 week after parturition. Among the mothers, all 24 patients were cured, and none of them died. The CBD stones in all 24 patients were completely removed with a two-step ERCP, and no serious post-ERCP complications occurred, although 2 patients had mild hemorrhage in the final ERCP to remove CBD stones. No recurrent pancreatitis or cholangitis occurred in patients who underwent ERBD. Among the infants, all survived without developmental problems or abnormality. Twenty infants were born at term; four infants were born prematurely at 35-37 weeks of gestation without developmental problems or complications. Emergency ERCP and ENBD without fluoroscopy in pregnant women with severe acute biliary pancreatitis are feasible and safe for both mothers and infants. It is also appropriate to remove CBD stones with two-step ERCP in pregnant women according to the stage of pregnancy.

    In this study, the authors introduce and evaluate the feasibility of endoscopic resection using the retroauricular approach for various benign lesions of the upper neck. A retrospective comparative analysis was performed on the clinical outcomes of patients who underwent surgery for upper neck masses as endoscopic resection using the retroauricular approach or conventional transcervical resection at the authors' center from January 2010 through August 2011. The primary outcome was the cosmetic satisfaction of the patients in each group. In addition, the feasibility of the procedure was evaluated by comparing the operation time; hospital stay; amount and duration of drainage; complications such as marginal mandibular nerve, lingual, or hypoglossal nerve palsy; paresthesia of the ear lobe; and wound problems such as hematoma and skin necrosis. Statistical analysis was performed by independent-samples t test and the Fisher exact test, and a P value less than .05 was considered statistically significant. Thirty-six patients underwent endoscopic resection (endo group; 15 men, 21 women; mean age, 38.8 ± 15.0 years) and 40 patients underwent conventional transcervical resection (conventional group; 18 men, 22 women; mean age, 45.1 ± 14.1 years). The operating time in the endo group was longer than in the conventional group (P = .003). No significant difference was observed in the overall perioperative complications between the 2 groups. Cosmetic satisfaction evaluated with a graded scale showed much better results in the endo group (P cosmetic results. Copyright © 2013 American Association of Oral and Maxillofacial Surgeons.

    Pseudoexfoliation syndrome (PEX) is the most frequently identifiable cause of secondary open-angle glaucoma, known as pseudoexfoliation glaucoma. The exact pathophysiology and etiology of PEX and associated glaucoma remains obscure. The purpose of this study was to determine the differences in the morphology of the anterior chamber angle in people with pseudoexfoliation syndrome and pseudoexfoliation glaucoma compared to a control group. We also evaluated the correlation between intraocular pressure (IOP) and pigmentation of the angle with the amount of exfoliated material in the anterior segment. The study group was composed of 155 eyes from 103 patients aged between 43 and 86 years. Each patient underwent a complete ophthalmological examination. Some difference was found in intraocular pressure between the PEX group and the control group and between the pseudoexfoliation glaucoma group and the control group, but no significant difference was found between the 2 study groups. There was a significant difference in the incidence of some degree of pigmentation in the anterior chamber angle and no difference in the widths of the angle between each group. A significant positive relationship was observed between intraocular pressure and the degree of pigmentation of the anterior chamber angle in both the PEX group and the pseudoexfoliation glaucoma group. The results of this study indicate that the amount of pigmentation and exfoliation material in the anterior segment significantly correlates with the level of IOP and possibly with the degree of trabecular dysfunction. It seems that for clear identification of PEX and pseudoexfoliation glaucoma factors, clinical assessment appears to be insufficient.

    Shrinkage and whitening of the anterior capsule opening - capsular contraction syndrome - is a well-known complication after continuous curvilinear capsulorrhexis. A 72-year-old women underwent continuous curvilinear capsulorrhexis, phacoemulsification, and implantation of posterior chamber intraocular lens with polymethylmethacrylate haptics. Four months postoperatively, the patient reported deterioration in visual acuity that was resulted due to complete occlusion of anterior capsular opening by fibrotic tissue. The fibrous membrane was excised surgically in capsulorrhexis fashion. (author)

    Full Text Available Abstract Background Loss of knee extension and a deficit in quadriceps strength are frequently found following anterior cruciate ligament (ACL reconstruction. The aim of this study was to investigate whether the addition of Eletromyographic Biofeedback (EMG BFB therapy for the vastus medialis muscle to the in the early phase of the standard rehabilitation programme could improve the range of knee extension and strength after ACL reconstruction more than a standard rehabilitation programme. The correlation between EMG measurement and passive knee extension was also investigated. Method Sixteen patients, all of whom underwent endoscopic ACL reconstruction using patellar tendon autograft, were randomly assigned to two groups: • Control group (8 patients: standard rehabilitation protocol; with full weight-bearing postoperative, knee brace (0° extension, 90° flexion, electrical stimulation, aquatics and proprioceptive training. • The EMG BFB group (8 patients: EMG BFB was added to the standard rehabilitation protocol within the first postoperative week and during each session for the next 6 weeks. Each patent attended a total of 16 outpatient physiotherapy sessions following surgery. High-Heel-Distance (HHD Test, range of motion (ROM and integrated EMG (iEMG for vastus medialis were measured preoperatively, and at the 1, 2, 4 and 6-week follow ups. Additionally, knee function, swelling and pain were evaluated using standardized scoring scales. Results At 6 weeks, passive knee extension (p  0.01 differences were found between the two groups for the assessment of knee function, swelling and pain. Conclusion The results indicate that EMG BFB therapy, in the early phase of rehabilitation after ACL reconstruction, is useful in enhancing knee extension. Improved innervation of the vastus medialis can play a key role in the development of postoperative knee extension. EMG BFB therapy is a simple, inexpensive and valuable adjunct to conventional

    2014-01-01

    Ankle arthrodesis is a common procedure that resolves many conditions of the foot and ankle; however, complications following this procedure are often reported and vary depending on the fixation technique. Various techniques have been described in the attempt to achieve ankle arthrodesis and there is much debate as to the efficiency of each one. This study aims to evaluate the efficiency of anterior plating in ankle arthrodesis using customised and Synthes TomoFix plates. We present the outcomes of 28 ankle arthrodeses between 2005 and 2012, specifically examining rate of union, patient-reported outcomes scores, and complications. All 28 patients achieved radiographic union at an average of 36 wk; the majority of patients (92.86%) at or before 16 wk, the exceptions being two patients with Charcot joints who were noted to have bony union at a three year review. Patient-reported outcomes scores significantly increased (P plate offers added compression and provides a rigid fixation for arthrodesis stabilization. PMID:24649408

    Nasal packings can aid in control of postoperative bleeding and healing following functional endoscopic sinus surgery (FESS), but traditional non-resorbable stents have several inherent drawbacks. We performed a randomized, controlled, multicenter clinical trial to assess efficacy of resorbable nasal packing in patients undergoing FESS for chronic rhinosinusitis. A total of 66 patients for 88 nasal cavities were randomized to receive either hyaluronan resorbable packing (MeroGel) or standard non-resorbable nasal dressing after FESS. All underwent preoperative rhinoscopy, CT of sinuses, and, after surgery, were reassessed by rhinoscopy at 2, 4, and 12 weeks in blinded fashion. A total of 44 nasal cavities (MeroGel-group) received resorbable packing, whereas the remaining 44 were packed with non-resorbable nasal dressing. At follow-up endoscopic visit, the presence of nasal synechia was evaluated as primary outcome. Moreover, the tolerability and surgical handling properties of MeroGel and its comfort were assessed by surgeons and patients. Preoperative severity of rhinosinusitis was similar in both groups. No significant adverse events were observed in all patients. Follow-up endoscopy showed a lower proportion of nasal adhesions in MeroGel-group at both 4 (P = 0.041) and 12 weeks (P appearance of nasal mucosa of nasal cavities after FESS was observed in the MeroGel-group. Tolerability and surgical handling properties of MeroGel were positively rated by clinicians and the overall patient judged comfort of MeroGel was favorable. In conclusion, MeroGel can be considered a valid alternative to standard non-resorbable nasal dressings. It is safe, well-accepted, well-tolerated, and has significant advantage of being resorbable. Moreover, it may favor improved healing in patients undergoing FESS and reduce formation of adhesions.

    We investigated into association of quality of life(QOL)and prognosis of breast cancer patients who underwent neoadjuvant chemotherapy(NAC). We retrospectively studied 228 patients with breast cancer who were performed NAC during a period between 2007 and 2015. TheQ OL score was measured with"The QOL Questionnaire for Cancer Patients Treated with Anticancer Drugs(QOL-ACD)". We evaluate association between QOL score with antitumor effect and prognosis. Changes in the QOL score between before and after NAC were compared as well. We divided 2 groups by QOL-ACD scoreinto high and low groups. Therapeautic effect of NAC on 75 patients were pathological complete response(pCR). QOL-ACD score was not significantly associated with pCR rate in both high and low groups(p=0.199). High group was significantly associated with higher survival rate in both of disease free survival(p=0.009, logrank)and overall survival(p=0.040, logrank). QOLACD score decreased after NAC in both of pCR and non-pCR patients. In conclusion, QOL evaluation using QOL-ACD could be an indicator of breast cancer patients' prognosis who underwent NAC.

    The role of HLA-G in several clinical conditions related to reproduction has been investigated. Important polymorphisms have been found within the 5'URR and 3'UTR regions of the HLA-G promoter. The aim of the present study was to investigate 16 SNPs in the 5'URR and 14-bp insertion/deletion (ins/del) polymorphism located in the 3'UTR region of the HLA-G gene and its possible association with the implantation outcome in couples who underwent assisted reproduction treatments (ART). The case group was composed of 25 ART couples. Ninety-four couples with two or more term pregnancies composed the control group. Polymorphism haplotype frequencies of the HLA-G were determined for both groups. The Haplotype 5, Haplotype 8 and Haplotype 11 were absolute absence in ART couples. The HLA-G*01:01:02a, HLA-G*01:01:02b alleles and the 14-bp ins polymorphism, Haplotype 2, showed an increased frequency in case women and similar distribution between case and control men. However, this susceptibility haplotype is significantly presented in case women and in couple with failure implantation after treatment, which led us to suggest a maternal effect, associated with this haplotype, once their presence in women is related to a higher number of couples who underwent ART.

    A geriatric assessment is needed to identify high-risk elderly patients with gastric cancer. However, the current geriatric assessment has been considered to be either time-consuming or subjective. The present study aimed to investigate the predictive effect of sarcopenia on the postoperative complications for elderly patients who underwent radical gastrectomy. We conducted a prospective study of patients who underwent radical gastrectomy from August 2014 to December 2015. Computed tomography-assessed lumbar skeletal muscle, handgrip strength, and gait speed were measured to define sarcopenia. Sarcopenia was present in 69 of 240 patients (28.8%) and was associated with lower body mass index, lower serum albumin, lower hemoglobin, and higher nutritional risk screening 2002 scores. Postoperative complications significantly increased in the sarcopenic patients (49.3% versus 24.6%, P sarcopenia (odds ratio: 2.959, 95% CI: 1.629-5.373, P Sarcopenia, presented as a new geriatric assessment factor, was a strong and independent risk factor for postoperative complications of elderly patients with gastric cancer.

    Full Text Available Background. S100B protein, previously proposed as a consolidated marker of brain damage in congenital heart disease (CHD newborns who underwent cardiac surgery and cardiopulmonary bypass (CPB, has been progressively abandoned due to S100B CNS extra-source such as adipose tissue. The present study investigated CHD newborns, if adipose tissue contributes significantly to S100B serum levels. Methods. We conducted a prospective study in 26 CHD infants, without preexisting neurological disorders, who underwent cardiac surgery and CPB in whom blood samples for S100B and adiponectin (ADN measurement were drawn at five perioperative time-points. Results. S100B showed a significant increase from hospital admission up to 24 h after procedure reaching its maximum peak (P0.05 have been found all along perioperative monitoring. ADN/S100B ratio pattern was identical to S100B alone with the higher peak at the end of CPB and remained higher up to 24 h from surgery. Conclusions. The present study provides evidence that, in CHD infants, S100B protein is not affected by an extra-source adipose tissue release as suggested by no changes in circulating ADN concentrations.

    Full Text Available Objective: To observe the effect of different CO2 pneumoperitoneum pressure on the stress state in patients underwent gynecological laparoscopy. Methods: A total of 90 patients who were admitted in our hospital from February, 2015 to October, 2015 for gynecological laparoscopy were included in the study and divided into groups A, B, and C according to different CO2 pneumoperitoneum pressure. The changes of HR, BP, and PetCO2 during the operation process in the three groups were recorded. The changes of stress indicators before operation (T0, 30 min during operation (T1, and 12 h after operation (T2 were compared. Results: The difference of HR, BP, and PetCO2 levels before operation among the three groups was not statistically significant (P>0.05. HR, BP, and PetCO2 levels 30 min after pneumoperitoneum were significantly elevated when compared with before operation (P0.05. PetCO2 level 30 min after pneumoperitoneum in group B was significantly higher than that in group A (P0.05. Conclusions: Low pneumoperitoneum pressure has a small effect on the stress state in patients underwent gynecological laparoscopy, will not affect the surgical operation, and can obtain a preferable muscular relaxation and vision field; therefore, it can be selected in preference.

    Per-oral endoscopic myotomy (POEM) represents a natural orifice endoscopic surgery (NOTES) approach to laparoscopy Heller myotomy (LHM). POEM is arguably the most successful clinical application of NOTES. The growth of POEM from a single center in 2008 to approximately 60 centers worldwide in 2014 with several thousand procedures having been performed attests to the success of POEM. Initial efficacy, safety and acid reflux data suggest at least equivalence of POEM to LHM, the previous gold standard for achalasia therapy. Adjunctive techniques used in the West include impedance planimetry for real-time intraprocedural luminal assessment and endoscopic suturing for challenging mucosal defect closures during POEM. The impact of POEM extends beyond the realm of esophageal motility disorders as it is rapidly popularizing endoscopic submucosal dissection in the West and spawning offshoots that use the submucosal tunnel technique for a host of new indications ranging from resection of tumors to pyloromyotomy for gastroparesis.

    Endoscopic nasobiliary drainage (ENBD) was often used for preoperative biliary drainage in cases like cholangiocarcinoma or acute obstructive suppurative cholangitis, reports on endoscopic nasobiliary drainage (ENBD) over primary closure of the common bile duct (CBD) are limited. This study compares outcomes of laparoscopic cholecystectomy (LC) + laparoscopic CBD exploration (LCBDE) + intraoperative ENBD + primary closure of CBD with equivalent patients who underwent preoperative endoscopic retrograde cholangiopancreatography (ERCP) and subsequent LC. From January 2013 to December 2015, 829 consecutive patients with choledocholithiasis combined with cholecystolithiasis underwent surgery in our department. 211 patients underwent LC + LCBDE + intraoperative ENBD + primary closure of CBD (group A) and 117 preoperative ERCP + subsequent LC (group B). A total of 501 patients (355 who underwent T-tube drainage and 146 who underwent transcystic exploration) were excluded from the analysis. Clinical records, operative findings, and postoperative follow-up were analyzed. Age and sex distribution, comorbidity, presentations, CBD diameter, and size and number of stones were similar in the two groups, and there was no postoperative mortality. Duration of surgery in group A was shorter (83 vs. 104 min, P choledocholithiasis combined with cholecystolithiasis.

    Objective Middle ear surgery increasingly employs endoscopes as an adjunct to or replacement for the operative microscope. Superior visualization and transcanal access to disease normally managed with a transmastoid approach are touted as advantages with the endoscope. No study, however, has systemically reviewed the literature to evaluate outcomes of endoscopic ear surgery (EES). We provide a systematic review of endoscope applications in middle ear surgery with an emphasis on outcomes. Data Sources PubMed, Embase, and Cochrane Methods A literature review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis recommendations. Articles were categorized based on study design, indication, and use of an endoscope either as an adjunct to or as a replacement for a microscope. Quantitative and descriptive analyses were performed. Results Ninety-one articles published between 1967 and 2014 met inclusion and exclusion criteria. The main indication for the use of an endoscope was cholesteatoma or myringoplasty. Of the identified articles, 40 provided a discrete discussion of outcomes. In cholesteatoma surgery, the endoscope has been mainly employed as an adjunct to the microscope, and although outcomes assessments vary across studies, the endoscope identified residual cholesteatoma in up to 50% of cases. Conclusion Endoscopes have been predominately used as an observational adjunct to the microscope to improve visualization of the tympanic cavity. Recent reports utilize the endoscope exclusively during surgical dissection; however, data comparing patient outcomes following the use of an operative endoscope versus a microscope are lacking. Areas in need of additional research are highlighted. PMID:25418475

    Dysphagia affects the most cardinal of human functions: the ability to eat and drink. The aim of this prospective study was to evaluate swallowing dysfunction in patients diagnosed with Zenker's diverticulum using the Swallowing Quality of Life (SWAL-QOL) questionnaire preoperatively. In addition, SWAL-QOL was used to assess changes in the outcome of swallowing function after endoscopic treatment of Zenker's diverticulum compared to baseline. Pre- and postoperative SWAL-QOL data were analyzed in 25 patients who underwent endoscopic treatment of Zenker's diverticulum between January 2011 and December 2013. Patients were treated by different endoscopic techniques, depending on the size of the diverticulum: CO 2 laser technique or stapler technique, or the combination of both techniques used in larger diverticula. Their mean age was 69 years, and 28% of patients were female. The mean interval between endoscopic surgery and completion of the postoperative SWAL-QOL was 85 days. The median (min-max) preoperative total SWAL-QOL score was 621 (226-925) out of 1100, indicating the perception of oropharyngeal dysphagia and diminished quality of life. Following endoscopic treatment of Zenker's diverticulum, significant improvement was demonstrated in the postoperative total SWAL-QOL score of 865 (406-1072) out of 1100 (p < 0.001). On the majority of subscales of SWAL-QOL there was significant improvement between pre- and postoperative scores. To the authors' knowledge, this is the first report in the literature on the changes in pre- and postoperative SWAL-QOL scores for patients with Zenker's diverticulum before and after treatment. The results of this study indicate that endoscopic treatment of Zenker's diverticulum leads to significant symptom relief as documented by significant changes in the majority of the SWAL-QOL domains.

    To identify risk factors of developing systemic inflammation response syndrome after endoscopic combined intrarenal surgery in the modified Valdivia position for renal stone treatment. We retrospectively analyzed 370 consecutive patients who underwent endoscopic combined intrarenal surgery procedures in the modified Valdivia position to treat renal stones. Antibiotic therapy based on preoperative urine cultures was administered to all patients from induction of anesthesia until at least postoperative day 3. Postoperative systemic inflammation response syndrome was diagnosed if the patient met two or more systemic inflammation response syndrome criteria. A multivariate logistic regression model with backward selection was used to evaluate the relationships between the incidence of systemic inflammation response syndrome after endoscopic combined intrarenal surgery and other clinical factors. Of the 370 patients, 61 patients (16.5%) were diagnosed with systemic inflammation response syndrome after endoscopic combined intrarenal surgery. Significant differences were found between the non-systemic inflammation response syndrome and systemic inflammation response syndrome groups with regard to female sex (29.8% vs 44.3%, P = 0.027), history of febrile urinary tract infection (16.5% vs 32.8%, P = 0.015) and number of involved calyces (2.68 vs 4.1, P systemic inflammation response syndrome: the number of involved calyces (P = 0.017), stone surface area (P = 0.021) and history of febrile urinary tract infection (P = 0.005). The number of involved calyces larger than four, stone surface area >500 mm(2) and a history of febrile urinary tract infection independently predicted the development of systemic inflammation response syndrome after endoscopic combined intrarenal surgery. This is the first study to identify the independent predictors of systemic inflammation response syndrome after endoscopic combined intrarenal surgery in the modified Valdivia position. © 2016 The

    Because the view angle of the endoscope is narrow, it is difficult to get the whole image of the digestive tract at once. If there are more than two lesions in the digestive tract, it is hard to understand the 3D positional relationship among the lesions. Virtual endoscopy using CT is a present standard method to get the whole view of the digestive tract. Because the virtual endoscopy is designed to detect the irregularity of the surface, it cannot detect lesions that lack irregularity including early cancer. In this study, we propose a method of endoscopic entire 3D image acquisition of the digestive tract using a stereo endoscope. The method is as follows: 1) capture sequential images of the digestive tract by moving the endoscope, 2) reconstruct 3D surface pattern for each frame by stereo images, 3) estimate the position of the endoscope by image analysis, 4) reconstitute the entire image of the digestive tract by combining the 3D surface pattern. To confirm the validity of this method, we experimented with a straight tube inside of which circles were allocated at equal distance of 20 mm. We captured sequential images and the reconstituted image of the tube revealed that the distance between each circle was 20.2 +/- 0.3 mm (n=7). The results suggest that this method of endoscopic entire 3D image acquisition may help us understand 3D positional relationship among the lesions such as early esophageal cancer that cannot be detected by virtual endoscopy using CT.

  9. Update on the endoscopic treatments for achalasia.

    Science.gov (United States)

    Uppal, Dushant S; Wang, Andrew Y

    2016-10-21

    Achalasia is the most common primary motility disorder of the esophagus and presents as dysphagia to solids and liquids. It is characterized by impaired deglutitive relaxation of the lower esophageal sphincter. High-resolution manometry allows for definitive diagnosis and classification of achalasia, with type II being the most responsive to therapy. Since no cure for achalasia exists, early diagnosis and treatment of the disease is critical to prevent end-stage disease. The central tenant of diagnosis is to first rule out mechanical obstruction due to stricture or malignancy, which is often accomplished by endoscopic and fluoroscopic examination. Therapeutic options include pneumatic dilation (PD), surgical myotomy, and endoscopic injection of botulinum toxin injection. Heller myotomy and PD are more efficacious than pharmacologic therapies and should be considered first-line treatment options. Per oral endoscopic myotomy (POEM) is a minimally-invasive endoscopic therapy that might be as effective as surgical myotomy when performed by a trained and experienced endoscopist, although long-term data are lacking. Overall, therapy should be individualized to each patient's clinical situation and based upon his or her risk tolerance, operative candidacy, and life expectancy. In instances of therapeutic failure or symptom recurrence re-treatment is possible and can include PD or POEM of the wall opposite the site of prior myotomy. Patients undergoing therapy for achalasia require counseling, as the goal of therapy is to improve swallowing and prevent late manifestations of the disease rather than to restore normal swallowing, which is unfortunately impossible.

    Achalasia is an esophageal motility disorder characterized by incomplete relaxation of the lower esophageal sphincter (LES) and aperistalsis of the esophageal body. Treatment of achalasia is aimed at decreasing the resting pressure in the LES. Peroral endoscopic myotomy (POEM), derived from natural orifice transluminal endoscopic surgery (NOTES) and advances in endoscopic submucosal dissection (ESD), presents a novel, minimally invasive, and curative endoscopic treatment for achalasia. POEM involves an esophageal mucosal incision followed by creation of a submucosal tunnel crossing the esophagogastric junction and myotomy before closure of the mucosal incision. Although the procedure is technically demanding and requires a certain degree of skill and competency, treatment success is high (90%) with low complication rates. Since the first described POEM in humans in 2010, it has been used increasingly at centers worldwide. This article reviews available published clinical studies demonstrating POEM efficacy and safety in order to present a proposal on how to establish a dedicated POEM program and reach base proficiency for the procedure.

  19. Endoscopic treatment of vesicoureteral reflux: Current status

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available Vesicoureteral reflux (VUR affects around 1% of all children. It carries an increased risk of febrile urinary tract infections (UTIs and is associated with impaired renal function. Endoscopic treatment with NASHA/Dx gel (dextranomer microspheres in a stabilized hyaluronic acid-based gel of nonanimal origin is minimally invasive, well tolerated and provides cure rates approaching those of open surgery: ~90% in several studies. It has also been shown to be effective in a variety of ′complicated′ cases. Endoscopic treatment is therefore considered preferable to open surgery and long-term antibiotic prophylaxis. Nontreatment of VUR is being discussed as an alternative option, whereby children are treated with antibiotics only when UTIs occur. Considering all the available evidence, however, active intervention with endoscopic treatment remains preferable. A new approach to managing VUR may nevertheless be considered, with treatment decisions based not only on the grade of reflux, but also factors such as age, sex, renal scarring, and bladder dysfunction. Open surgery would be reserved for use only in the ~10% of children not responding to endoscopic treatment, and patients with refluxing primary megaureter.

    Full Text Available Traumatic acute subdural hematoma (ASDH is generally addressed by craniotomy under general anesthesia. We report a patient whose traumatic ASDH was treated under local anesthesia by one-burr-hole endoscopic surgery. This 87-year-old woman had undergone coil embolization for a ruptured right middle-cerebral artery aneurysm and placement of a ventriculoperitoneal shunt for normal pressure hydrocephalus 5 years earlier. Upon admission, she manifested consciousness disturbance after suffering head trauma and right hemiplegia. Her Glasgow Coma Scale score was 8 (E2V2M4. Computed tomography (CT demonstrated a thick, left-frontotemporal ASDH. Due to her advanced age and poor condition, we performed endoscopic surgery rather than craniotomy to evacuate the ASDH. Under local anesthesia, we made a burr hole in her left forehead and increased its size to 15 mm in diameter. After introducing a transparent sheath into the hematoma cavity with a rigid endoscope, the clot was evacuated with a suction tube. The arterial bleeding point was electrically coagulated. A postoperative CT scan confirmed the reduction of the hematoma. There was neither brain compression nor brain swelling. Her consciousness disturbance and right hemiplegia improved immediately. Endoscopic surgery may represent a viable method to address traumatic intracranial hematomas in some patients.

    To evaluate the pattern of anterior segment indocyanine green (ICG) angiography in episcleritis and scleritis. Prospective comparative (paired-eye) observational case series. Twenty subjects presenting clinical diseases compatible with episcleritis or scleritis. Anterior segment ICG angiography was performed according to a standard protocol in subjects presenting either episcleritis or scleritis. Photographs of the anterior segment were taken in the early phase (up to 3 minutes after dye injection), intermediate phase (10-12 minutes) and late phase (30-45 minutes). The inflamed zones were compared with the same regions of the controlateral eye. The amount of protein ICG exudation was scored by a masked observer as follows: zero for no exudation, one for slight exudation, two for moderate exudation, and three for severe exudation. Evaluation of dye leakage, which reflects protein exudation, with anterior segment ICG angiography in episcleritis and scleritis. Twenty subjects with a mean age of 43 +/- 15 years (7 male, 13 female) were enrolled in the study. Thirteen subjects had anterior scleritis (7 nodular, 5 diffuse, and 1 scleromalacia perforans), and 7 subjects had episcleritis. Only 1 out of 7 subjects with episcleritis showed a slight ICG leakage (a score of one), whereas all subjects with scleritis had ICG leakage scores of one or more (P = 0.0005, Fisher exact test). ICG angiography of the anterior segment of the eye is a good clinical test to differentiate episcleritis from scleritis.

    Full Text Available Objectives: To report the intraoperative and postoperative follow-up complications and management of these in deep anterior lamellar keratoplasty (DALK surgery. Materials and Methods: Two hundred eighty-four eyes of 252 patients followed up in our cornea clinic who underwent DALK using Anwar’s big-bubble technique with healthy Descemet’s membrane and endothelium were included in this study. Intraoperative and postoperative complications as well as the management and treatment of these complications were evaluated. Results: Big bubble was created in 220 (77.5% eyes of 284 eyes, and lamellar dissection was performed in 64 (22.5% eyes. Perforation occurred during trephination in 4 eyes, and the procedure was accomplished by penetrating keratoplasty (PK. Intraoperative microperforation occurred in 44 eyes. Perforation enlarged in 4 eyes and PK was performed. Operation was continued in 40 eyes with air injection into the anterior chamber. In postopertive follow-up period, double anterior chamber (DAC occurred in 32 of 40 eyes. DAC spontaneously regressed in 8 eyes, and air was given into the anterior chamber with a second surgical intervention in 24 eyes. DAC improved in 20 eyes. Four eyes underwent PK. Fungal keratitis evolved at the interface in one eye, because of no healing during the follow-up period, this eye underwent PK under antifungal therapy. Eyes with interface haze and Descemet’s membrane folds were followed. Conclusion: DALK is a difficult technique with a steep learning curve. In addition to the complications seen in PK, specific complications can occur in lamellar surgery. (Turk J Ophthalmol 2014; 44: 337-40

    Full Text Available ABSTRACT Objective: To report the outcomes of non-endoscopic percutaneous cervical discectomy by anterior blunt approach for the treatment of degenerative disc disease. Methods: A review of the medical records of patients with axial cervical pain resulting from degenerative disc disease and treated with discectomy and percutaneous nucleoplasty by anterior blunt approach with radiofrequency source was carried out. The data were evaluated according to modified MacNab and pre- and postoperative VAS criteria at 3, 12 and 24 months. Results: Sixty-two procedures were performed in 48 patients between 2008 and 2014. The mean age of the population was 52.4 years. MacNab results were 84.6%, 92.3%, and 89.2% improvement (excellent and good results at 3, 12 and 24 months, respectively. The VAS changed from 7.4 to 2.3 two years after the procedure, showing a statistically significant difference (p=0.000. There were no major complications or re-interventions related to the technique. Conclusions: Anterior non-endoscopic discectomy and nucleoplasty for the treatment of discogenic axial cervical pain may be an effective alternative to open surgery. In the two-year follow-up, our blunt technique proved to be a safe procedure with no approach-related complications, and provided outcomes comparable to those reported using the original needle technique.

    Laryngeal webs and epiglottic hypoplasias are uncommon congenital anomalies. Anterior glottic web combined with epiglottic hypoplasia was found in a middle-aged man presenting with hoarseness and dyspnea on exertion. This can be considered as a unique isolated defect of the larynx during early fetal development. The laryngeal web can be successfully treated in a single stage with endoscopic lysis and topical application of mitomycin C for prevention of anterior glottic restenosis. This case and prior reports suggest that the novel approach may be effective in the treatment of laryngeal webs.

    Echo-endoscopes are much stiffer and thicker than regular endoscopes. During the procedure of endoscopic ultrasound (EUS) procedure, water irrigation is a very useful for imaging but very dangerous if the patient receive the procedure under anesthesia without intubation. In this study, we evaluated the safety and effectiveness of nitrous oxide (N2O) (≤70%) for EUS. Among 4230 patients who underwent EUS from December 2012 to December 2013, 347 out patients who need irrigation during the procedure were enrolled and divided into Group A. Group A (N2O sedation group, n = 162) and Group B (no sedative group, n = 185). For Group A, patients received N2O by inhalation during the procedure. The mixture rate of N2O and O2 was 45-65% and controlled by nurses according to individual effect. The cardiorespiratory functions, procedure duration, complications, and visual analog scale (VAS) of the patient and examiner satisfaction were compared. Both group had comparable diagnostic accuracy, but VAS of the patients who received N2O sedation was higher than that in Group B (7.5 vs. 4.5, P need irrigation.

    Full Text Available Aim: Minimally invasive interventions have become increasingly popular with the developments in technology and surgical tools. In this article, we present our experience with 67 cases of percutaneous transforaminal endoscopic lumbar discectomy. Material and Method: A total of 67 cases that underwent endoscopic surgery for foraminal and extraforaminal disc hernia between 2004 and 2010 were retrospectively examined. Results: The mean pre-operative VAS score was 8.13. The mean post-operative VAS score was 2.4 in the 1st month and 2.01 in the 12th month. Satisfaction according to MacNab criteria in the 12th month was excellent in 35 (52.2% patients, good in 18 (26.9% patients, fair in 11 (16.4% patients, and poor in 3 (4.5% patients. Microdiscectomy was required due to continuing symptoms in 3 patients (4.5%. Temporary dysesthesia was found in 3 patients. Discussion: Percutaneous endoscopic discectomy has become a good alternative to microsurgery for foraminal and extraforaminal disc herniations because of the developments in technology and surgical tools as well as the increased experience of surgeons. The technique is not limited to these localizations; it can also be used for free fragments within the channel, recurrent disc herniations, and narrow channels.

    The aim of this study was to evaluate audiological outcomes following adenoidectomy by the classical method and by endoscopically-assisted adenoidectomy using a powered instrument (microdebrider). This study was conducted in a tertiary care center. It included 40 patients divided into two equal groups of 20 each. Group-A patients underwent classical adenoidectomy, while Group-B patients were subjected to endoscopically-assisted adenoidectomy using a microdebrider. Hearing outcome was measured by post-operative pure-tone audiometry and tympanometry. The post-operative average air-bone gap (ABG) was reduced from 19.6 dB to 11.8 dB in Group A and from 17.6 dB to 8.7 dB in Group B (P=0.010). There was reversal of tympanometric curves from type-B and type-C to type-A in 55% of the patients in Group A, while type-A curve was seen in 90% cases in Group B in the post-operative period. Audiological outcomes of endoscopically-assisted adenoidectomy using a microdebrider were superior compared with classical adenoidectomy.

    The aim of this study was to assess the safety and efficacy of large balloon sphincteroplasty when used in conjunction with endoscopic biliary sphincterotomy during endoscopic retrograde cholangiopancreatography (ERCP) for therapy of choledocholithiasis. A retrospective audit of all ERCP's performed for choledocholithiasis between January 2012 and October 2013 at one institution was performed. Procedures that utilized large balloon sphincteroplasty were compared with those underwent standard endoscopic stone extraction. Outcomes including stone clearance rate for the individual procedure type, post-ERCP complications and need for surgical exploration of the bile duct were documented. A total of 346 procedures on 306 patients that met the inclusion criteria were identified. Fifty-four (15.6%) procedures included large balloon sphincteroplasty and were compared with 292 (84.4%) procedures that used standard balloon extraction techniques. Despite those patients in the large balloon sphincteroplasty group having a higher rate of previous ERCP (33.3% versus 19.5%, P = 0.031) and a larger proportion of patients with stones greater than 10 mm (40.3% versus 11.3%, P choledocholithiasis. The current study demonstrated large balloon sphincteroplasty did not result in more complications despite a tendency to being used for larger stones. © 2014 Royal Australasian College of Surgeons.

    Choledocholithiasis is one of the causes of jaundice and may require urgent treatment. Endoscopic retrograde cholangiopancreatography (ERCP) has been the primary management strategy for choledocholithiasis. However, small stones can be overlooked during ERCP. The aim of this study was to evaluate the accuracy of intraductal ultrasonography (IDUS) for detecting choledocholithiasis in icteric patients with highly suspected common bile duct (CBD) stones without definite stone diagnosis on ERCP. Ninety-five icteric (bilirubin ≥ 3 mg/dL) patients who underwent ERCP for highly suspected choledocholithiasis without definite filling defects on cholangiography were prospectively enrolled in the present study. We evaluated the bile duct using IDUS for the presence of stones or sludge. Reference standard for choledocholithiasis was endoscopic extraction of stone or sludge. Bile duct stones were detected with IDUS in 31 of 95 patients (32.6%). IDUS findings were confirmed by endoscopic stone extraction in all patients. The mean diameter of CBD stones detected by IDUS was 2.9 mm (range 1-7 mm). IDUS revealed biliary sludge in 24 patients (25.2%) which was confirmed by sludge extraction in 21 patients (87.5%). In dilated CBD, detection rate of bile duct stone/sludge based on IDUS was significantly higher than in non-dilated CBD (p = 0.004). IDUS is useful for the detection of occult CBD stone on ERCP in icteric patients with highly suspected CBD stones.

    To assess the ultrasonographic (US) findings of foreign body granulomas detected by endoscopic thyroidectomy. On positron emission tomography computed tomography of patients who had undergone endoscopic thyroidectomy, we encountered three fluorodeoxyglucose uptaken lesions in the surgical bed and those were pathologically confirmed to be foreign body granulomas. Additionally, 10 lesions demonstrating the same US findings were clinically diagnosed as foreign body granulomas. Echogenicity, shape, size, location, and vascularity were evaluated on US. Eleven lesions were subjected to follow up US. On US, seven lesions were found to be hyperechoic linear lesions with posterior acoustic shadowing while six other lesions were oval, iso to slightly hypoechoic lesions. No vascularity was observed on color Doppler US. The size of the lesions was inversely correlated with the time to lesion detection (Spearman's correlation r = -0.6528; p = 0.02). Oval iso to slightly hypoechoic lesions (mean, 672 days) had statistically longer times from the time of thyroidectomy to lesion detection on US than hyperechoic linear lesions (mean, 318 days; Mann Whitney test, p = 0.02). On follow up US, the lesions had decreased in size and hyperechoic linear lesions became oval iso to slightly hypoechoic lesions. In patients who underwent endoscopic thyroidectomy, characteristic US findings and evolutional changes are helpful for the diagnosis of foreign body granulomas and to distinguish from recurrent thyroid cancer, thus avoiding invasive procedures.

    Biliary obstruction in chronic calcific pancreatitis (CCP) is often caused by inflammatory or fibrotic strictures of the bile duct, carcinoma of head of pancreas or less commonly by compression from pseudocysts. Pancreatic calculi causing ampullary obstruction and leading to obstructive jaundice is extremely rare. The medical records of all patients with CCP or biliary obstruction who underwent endoscopic retrograde cholangiopancreatography (ERCP) over 4 years between 2010-2014 at Kasturba Medical College, Manipal were analyzed. Five patients of CCP with impacted pancreatic calculi at the ampulla demonstrated during ERCP were identified. All 5 presented with biliary obstruction and were incidentally detected to have CCP when evaluated for the same; 3 patients had features of cholangitis. All the patients were managed successfully by endoscopic papillotomy and extraction of pancreatic calculi from the ampulla with resolution of biliary obstruction. Pancreatic calculus causing ampullary obstruction, though very rare, should be considered as a possibility in patients with CCP complicated by biliary obstruction. Endoscopic therapy is affective in the resolution of biliary obstruction in such patients.

    We evaluated postoperative changes in nasal cavity dimensions and their effects on nasal functions and symptoms. Case series with chart review. Tertiary referral center. We studied patients who underwent binostril, 4-hand endoscopic endonasal transsphenoidal approach surgery with the bilateral modified nasoseptal rescue flap technique. Pre- and postoperative paranasal computed tomography scans were used to assess nasal cavity dimensional changes at 4 levels. We also performed several pre- and postoperative tests, including the Connecticut Chemosensory Clinical Research Center test and the Cross-Cultural Smell Identification Test (n = 119) to evaluate olfactory functions. Also, the Nasal Obstruction Symptoms Evaluation, the Sino-Nasal Outcome Test-20, and a visual analog scale were used (n = 157) to record subjective symptoms. We compared these data with the pre- and postoperative nasal cavity dimensions. Two-dimensional objective increases in nasal passage dimensions were evident postoperatively (all cross-sectional areas, P Cultural Smell Identification Test (all cross-sectional areas, P ≥ .05). Endoscopic endonasal transsphenoidal approach surgery altered the patients' nasal anatomy, but the changes in nasal cavity dimensions did not affect nasal functions and symptoms. These results will help surgeons to appropriately expose the surgical field during endoscopic endonasal transsphenoidal approach surgery. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

    Robotic technology may be a promising tool in reduction of morbidity in radical anterior pelvic exenteration for invasive bladder cancer. We report our initial experience with robotic-assisted radical anterior pelvic exenteration in females in an attempt to evaluate the technique's feasibility and outcomes. A retrospective review of our bladder cancer database was performed. Twelve women that underwent robotic-assisted radical anterior pelvic exenteration, bilateral pelvic lymphadenectomy, and urinary diversion for clinically localized urothelial carcinoma of the bladder between 2004 and 2008 were included in this retrospective study. Median age was 73.0 +/- 9.6 years and median body mass index (BMI) was 23.5 +/- 5.0 kg/m2. Ten patients underwent ileal conduit diversion, one had an orthotopic neobladder and one an Indiana pouch. Median total operating time was 6.4 +/- 1.5 hours with median console and diversion times of 4.7 +/- 0.9 and 2.5 +/- 1.5 hours respectively. Median blood loss was 275.0 +/- 165.8 ml. Median length of stay was 8.0 +/- 1.6 days. Four patients were T2N0 or less, five T3N0, one T3N1 and two patients T4N0. There was one patient with positive surgical margins. Median number of lymph nodes removed was 23.0 +/- 11.4. Median follow-up of 9.0 +/- 6.0 months was available for ten patients. One had a recurrent ureteroenteric stricture, one had colpocleisis for vault prolapse, and three had metastatic disease. Robotic-assisted laparoscopic anterior pelvic exenteration appears to be a favorable surgical option with acceptable operative, pathological, and short-term clinical outcomes. According to the UCI experience, robotic anterior exenteration appears to achieve the clinical and oncologic goals for the surgical treatment of bladder cancer.

    Full Text Available Cushing’s syndrome (CS may lead to severe maternal and fetal morbidities and even mortalities in pregnancy. However, pregnancy complicates the diagnosis and treatment of CS. This study describes a 26-year-old pregnant woman admitted with hypertension-induced headache. Hormonal analyses performed due to her cushingoid phenotype revealed a diagnosis of adrenocorticotropic hormone- (ACTH- independent CS. MRI showed a 3.5 cm adenoma in her right adrenal gland. After preoperative metyrapone therapy, she underwent a successful unilateral laparoscopic adrenalectomy at 14-week gestation. Although she had a temporary postoperative adrenal insufficiency, hormonal analyses showed that she has been in remission since delivery. Findings in this patient, as well as those in previous patients, indicate that pregnancy is not an absolute contraindication for laparoscopic adrenalectomy. Rather, such surgery should be considered a safe and efficient treatment method for pregnant women with cortisol-secreting adrenal adenomas.

    Compare the visual acuity of patients who underwent cataract surgery by phacoemulsification with IOL AcrySof(®) toric implantation versus AcrySof(®) IQ and evaluate the reduction of cylindrical diopters (CD) in the postoperative period. Analytical and retrospective study of 149 eyes with 1 or more diopters of regular symmetrical keratometric astigmatism, which underwent cataract surgery by phacoemulsification. The eyes were divided into two groups: the toric group with 85 eyes and the non-toric group with 64 eyes. In the pre-operative phase, topographic data and refraction of each eye to be operated were assessed. In the postoperative phase, refraction and visual acuity with and without correction were measured. The preoperative topographic astigmatism ranged from 1.00 to 5.6 DC in both groups. Average reduction of 1.37 CD (p<0.001) and 0.16 CD (p=0.057) was obtained for the toric and non-toric group when compared to the refractive astigmatism, respectively. Considering visual acuity without correction (NCVA), the toric group presented 44 eyes (51.7%) with NCVA of 0 logMAR (20/20) or 0.1 logMAR (20/25) and the toric group presented 7 eyes (10.93%) with these same NCVA values. The results show that patients with a significant keratometric astigmatism presented visual benefits with the toric IOL implantation. The reduction of the use of optical aids may be obtained provided aberrations of the human eye are corrected more accurately. Currently, phacoemulsification surgery has been used not only for functional improvement, but also as a refraction procedure.

    To determine the effects of total parenteral nutrition (TPN) and enteral nutrition (EN) on biochemical and clinical outcomes in pancreatic cancer patients who underwent pancreaticoduodenectomy. From the year 2006 to 2008, 60 patients who underwent pancreaticoduodenectomy in Tianjin Third Central Hospital were enrolled in this study. They were randomly divided into the EN group and the TPN group. The biochemical and clinical parameters were recorded and analyzed between the two groups. There was no significant difference in the nutritional status, liver and kidney function, and blood glucose levels between the TPN and EN groups on the preoperative day, the 1st and 3 rd postoperative days. However, on the 7th postoperative day, there was significant difference between the two groups in 24 h urinary nitrogen, serum levels of, total protein (TP), transferrin (TF), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and γ-glutamyl transpeptadase (GGT), blood urea nitrogen (BUN) and creatinine (Cr). On the 14th postoperative day, there was a significant difference between the two groups in terms of urinary levels of 24 h nitrogen, TP, TF, retinol binding protein, ALT, AST, ALP, GGT, total bilirubin, direct bilirubin, BUN, Cr, and glucose. The incidence of delayed gastric emptying in the EN and TPN groups was 0% and 20%, respectively. Moreover, the incidence of pancreatic fistulas and hemorrhages in the EN group were 3.6% and 3.6%, versus 26.7% and 30% in the TPN group, respectively. EN is better than TPN for pancreatic cancer patients who received pancreaticoduodenectomy.

    Obtaining an adequate mucosal closure is one of the crucial steps in per-oral endoscopic myotomy (POEM). Thus far, there have been no objective data comparing the various available closure techniques. This case-controlled study attempts to compare the application of endoscopic clips versus endoscopic suturing for mucosotomy closure during POEM cases. A retrospective review of our prospective POEM database was performed. All cases in which endoscopic suturing was used to close the mucosotomy were matched to cases in which standard endoclips were used. Overall complication rate, closure time and mucosal closure costs between the two groups were compared. Both techniques offer good clinical results with good mucosal closure and the absence of postoperative leak. Closure time was significantly shorter (p = 0.044) with endoscopic clips (16 ± 12 min) when compared to endoscopic suturing (33 ± 11 min). Overall, the total closure cost analysis showed a trend toward lower cost with clips (1502 ± 849 USD) versus endoscopic suturing (2521 ± 575 USD) without reaching statistical significance (p = 0.073). The use of endoscopic suturing seems to be a safe method for mucosal closure in POEM cases. Closure time is longer with suturing than conventional closure with clips, and there is a trend toward higher overall cost. Endoscopic suturing is likely most cost-effective for difficult cases where conventional closure methods fail.

  1. Endoscopic management of biliary injuries and leaks

    Full Text Available Bile duct injuries and subsequent leaks can occur following laparoscopic and open cholecystectomies and also during other hepatobiliary surgeries. Various patient related and technical factors are implicated in the causation of biliary injuries. Over a period of twenty five years managing such patients of biliary injuries our team has found a practical approach to assess the cause of biliary injuries based on the symptoms, clinical examination and imaging. Bismuth classification is helpful in most of the cases. Immediate referral to a centre experienced in the management of bile duct injury and timely intervention is associated with improved outcomes. Resuscitation, correcting dyselectrolytemia, aspiration of undrained biloma and antibiotics take the priority in the management. The goal is to restore the bile conduit, and to prevent short and longterm complications such as biliary fistula, intra-abdominal abscess, biliary stricture, recurrent cholangitis and secondary biliary cirrhosis. Endoscopic therapy by reducing the transpapillary pressure gradient helps in reducing the leak. Endoscopic therapy with biliary sphincterotomy alone or with additional placement of a biliary stent/ nasobiliary drainage is advocated. In our tertiary care referral unit, we found endoscopic interventions are useful in situations where there is leak with associated CBD calculus or a foreign body, peripheral bile duct injury, cystic duct stump leak and partial bile duct injury with leak/ narrowing of the lumen. Endotherapy is not useful in case of complete transection (total cut off and complete stricture involving common hepatic or common bile ducts. In conclusion, endoscopic treatment can be considered a highly effective therapy and should be the first-line therapy in such patients. Though less successful, an endoscopic attempt is warranted in patients suffering from central bile duct leakages failing which surgical management is recommended.

    Congenital bilateral agenesis of the tibialis anterior muscles is a rare condition. We present a case of congenital absence of bilateral tibialis anterior muscles in a 6-year-old boy who presented with an abnormal gait. He was previously diagnosed to have bilateral congenital talipes equinovarus (CTEV) deformity for which he underwent corrective surgery two times. However, he still had a residual foot problem and claimed to have difficulty in walking. On examination, he walked with a high stepping gait and muscle power of both lower limbs was 5/5 on the medical research council scale (MRCS) except for both ankle dorsiflexors and long toe extensors. The sensation was intact. Magnetic Resonance Imaging (MRI) study of both legs revealed that tibialis anterior muscles were not visualized on both sides suggestive of agenesis of the tibialis anterior muscles. The rest of the muscles appeared mildly atrophied. The electrophysiological study showed normal motor and sensory conduction in both upper and lower limbs. Electromyographic (EMG) study of the vastus medialis was within normal limit and no response could be elicited for EMG of tibialis anterior muscles suggesting possible absence of tibialis anterior muscles, bilaterally. The patient underwent split tibialis posterior tendon transfer to achieve a balanced and functional foot and was well on discharge. The present case describes the normal anatomy and embryology of tibialis anterior muscles as well as possible causes of its agenesis along with its clinical implications.

    Objective. To develop a new method of magnetic resonance arthrography (MRA) of the knee using an anterior approach analogous to the portals used for knee arthroscopy.Design. An anterior approach to the knee joint was devised mimicking anterior portals used for knee arthroscopy. Seven patients scheduled for routine knee MRA were placed in a decubitus position and under fluoroscopic guidance a needle was advanced from a position adjacent to the patellar tendon into the knee joint. After confirmation of the needle tip location, a dilute gadolinium solution was injected.Results and conclusion. All the arthrograms were technically successful. The anterior approach to knee MRA has greater technical ease than the traditional approach with little patient discomfort. (orig.)

    Despite the increasing application of endoscopic transsphenoidal surgery for pituitary lesions, the prognostic factors that are associated with sinonasal quality of life (QOL) and nasal morbidity are not well understood. The authors examine the predictors of sinonasal QOL and nasal morbidity in patients undergoing fully endoscopic transsphenoidal surgery. An exploratory post hoc analysis was conducted of patients who underwent endoscopic pituitary surgery and were enrolled in a prospective multicenter QOL study. End points of the study included patient-reported sinonasal QOL and objective nasal endoscopy findings. Multivariate models were developed to determine the patient and surgical factors that correlated with QOL at 2 weeks through 6 months after surgery. This study is a retrospective review of a subgroup of patients studied in the clinical trial "Rhinological Outcomes in Endonasal Pituitary Surgery" (clinical trial no. NCT01504399, clinicaltrials.gov ). Data from 100 patients who underwent fully endoscopic transsphenoidal surgery were included. Predictors of a lower postoperative sinonasal QOL at 2 weeks were use of nasal splints (p = 0.039) and female sex at the trend level (p = 0.061); at 3 months, predictors of lower QOL were the presence of sinusitis (p = 0.025), advancing age (p = 0.044), and use of absorbable nasal packing (p = 0.014). Health status (multidimensional QOL) was also predictive at 2 weeks (p = 0.001) and 3 months (p < 0.001) and was the only significant predictor of sinonasal QOL at 6 months (p < 0.001). A Kaplan-Meier analysis was performed to study time to resolution of nasal crusting, mucopurulence, and synechia as observed during nasal endoscopy after surgery. The mean time (± SEM) to absence of nasal crusting was 16.3 ± 2.1 weeks, mucopurulence was 6.2 ± 1.1 weeks, and synechia was 4.4 ± 0.5 weeks. Use of absorbable nasal packing was associated with more severe mucopurulence. Sinonasal QOL following endoscopic pituitary surgery

    Gastric per-oral endoscopic myotomy (G-POEM) recently has been reported as minimally invasive therapy for gastroparesis. The aims of this study were to report on the first multicenter experience with G-POEM and to assess the efficacy and safety of this novel procedure for patients with gastroparesis with symptoms refractory to medical therapy. All patients with gastroparesis who underwent endoscopic pyloromyotomy (G-POEM) at 5 medical centers were included. Procedures were performed following the same principles as esophageal POEM. Clinical response was defined as improvement in gastroparetic symptoms with absence of recurrent hospitalization. Adverse events were graded according to the American Society for Gastrointestinal Endoscopy lexicon. A total of 30 patients with refractory gastroparesis (11 diabetic, 12 postsurgical, 7 idiopathic) underwent G-POEM. Previous therapies included Botox injection in 12, transpyloric stenting in 3, and PEG with jejunal extension (PEGJ) in 1. Nausea/vomiting were the predominant symptoms in 25 patients. Weight loss was present in 27 patients with an average of 10% loss of body weight. G-POEM was completed successfully in all 30 (100%) patients with a mean procedure time of 72 minutes (range, 35-223 min). The mean myotomy length was 2.6 ± 2.3 cm. The mean length of hospital stay was 3.3 days (range, 1-12 days). Two adverse events occurred in 2 (6.7%) patients, including 1 capnoperitoneum and 1 prepyloric ulcer, rated as mild and severe, respectively. Clinical response was observed in 26 (86%) patients during a median follow-up of 5.5 months. Four patients (2 diabetic, 1 postsurgical, 1 idiopathic cause) did not respond to G-POEM. Repeat gastric emptying scan was obtained in 17 patients, normalized in 8 (47%), and improved in 6 (35%) patients. G-POEM is a technically feasible procedure. This small non-randomized study suggests the effectiveness of G-POEM for the treatment of patients with gastroparesis refractory to medical

    To compare the extent of cage subsidence after anterior cervical discectomy and fusion (ACDF) using a cage alone or combined with anterior plate fixation, and to assess the effect of end plate removal on cage subsidence. Records of 23 men and 13 women aged 32 to 82 (mean, 54) years who underwent ACDF for 61 levels using the Solis cage alone (n=46) or combined with anterior plate fixation (n=15) were reviewed. The extent of cage subsidence was determined by comparing immediately postoperative (within one week) with final follow-up radiographs. Cage subsidence was defined as the sum subsidence of the superior and inferior part of the cage into the vertebral body. Mild and major cage subsidence was defined as ≤2 mm and >2 mm, respectively. Patients who underwent ACDF using a cage alone or combined with anterior plate fixation were comparable in terms of age, gender, follow-up duration, and number of levels decompressed. Cage subsidence occurred in 33 (54%) of the 61 levels decompressed. In the cage alone group, the extent of cage subsidence was greater (1.68 vs. 0.57 mm, p=0.039) and the rate of major cage subsidence was higher (28% vs. 7%, p=0.08). The inferior part of the cage was more vulnerable to subsidence compared with the superior part (median subsidence: 3.0 vs. 1.4 mm, psubsidence occurred more often when the end plate was removed rather than preserved (58% vs. 18%, psubsidence was greater after ACDF with cage alone. Cage subsidence occurred more often when the end plate was removed. Additional anterior plate fixation is recommended when the end plate is removed.

    Bowel anastomosis after anterior resection is one of the most difficult tasks to perform during laparoscopic colorectal surgery. This study aims to evaluate a new feasible and safe intracorporeal anastomosis technique after laparoscopic left-sided colon or rectum resection in a pig model. The technique was evaluated in 5 pigs. The OrVil device (Covidien, Mansfield, Massachusetts) was inserted into the anus and advanced proximally to the rectum. A 0.5-cm incision was made in the sigmoid colon, and the 2 sutures attached to its delivery tube were cut. After the delivery tube was evacuated through the anus, the tip of the anvil was removed through the perforation. The sigmoid colon was transected just distal to the perforation with an endoscopic linear stapler. The rectosigmoid segment to be resected was removed through the anus with a grasper, and distal transection was performed. A 25-mm circular stapler was inserted and combined with the anvil, and end-to-side intracorporeal anastomosis was then performed. We performed the technique in 5 pigs. Anastomosis required an average of 12 minutes. We observed that the proximal and distal donuts were completely removed in all pigs. No anastomotic air leakage was observed in any of the animals. This study shows the efficacy and safety of intracorporeal anastomosis with the OrVil device after laparoscopic anterior resection.

    Malignant gastric outlet obstruction (GOO) is a pre-terminal event in the natural history of gastric and pancreaticobiliary cancers. The use of endoscopic placement of self-expandable metallic stents (SEMS) is a less invasive alternative palliative option for these patients. This is the first study in Southeast Asia to evaluate the clinical efficacy and safety of endoscopic SEMS placement in patients with malignant GOO. A retrospective review of our department's database in endoscopic SEMS placement for the treatment of malignant GOO was performed. Twenty-four patients with advanced or metastatic malignancy that underwent placement of SEMS for treatment of malignant GOO between January 2003 and July 2013 were analysed. The GOO severity score was used as an objective means of assessing patients' oral intake. Technical success rate was 100%. All patients resumed oral intake of liquids within the same day of stent placement. Clinical success was achieved in 21 patients (87.5%). There was a significant improvement of GOO severity score from 0.62 ± 1.0 (mean ± standard deviation) before stent placement to 2.04 ± 0.86 after stent placement (P < 0.001). Complication rate was 12.5%. Stent-related complications observed include stent migration (two patients) and tumour ingrowth (one patient). Serious complications such as gastrointestinal haemorrhage or perforation did not occur in any patients. The median survival after stent placement was 57 days (95% confidence interval, 12.2-101.8 days). None of the patients died from stent-related complications. Endoscopic SEMS placement is a minimally invasive, safe and effective option for the palliation of malignant GOO. © 2014 Royal Australasian College of Surgeons.

    Gastroesophageal variceal bleeding in patients with cirrhosis is associated with significant morbidity and mortality, as well as a high rebleeding risk. Limited data are available on the role of transjugular intrahepatic portosystemic shunt (TIPS) with covered stents in patients receiving standard endoscopic, vasoactive, and antibiotic treatment. In this multicenter randomized trial, long-term endoscopic variceal ligation (EVL) or glue injection + β-blocker treatment was compared with TIPS placement in 72 patients with a first or second episode of gastric and/or esophageal variceal bleeding, after hemodynamic stabilization upon endoscopic, vasoactive, and antibiotic treatment. Randomization was stratified according to Child-Pugh score. Kaplan-Meier (event-free) survival estimates were used for the endpoints rebleeding, death, treatment failure, and hepatic encephalopathy. During a median follow-up of 23 months, 10 (29%) of 35 patients in the endoscopy + β-blocker group, as compared to 0 of 37 (0%) patients in the TIPS group, developed variceal rebleeding (P = 0.001). Mortality (TIPS 32% vs. endoscopy 26%; P = 0.418) and treatment failure (TIPS 38% vs. endoscopy 34%; P = 0.685) did not differ between groups. Early hepatic encephalopathy (within 1 year) was significantly more frequent in the TIPS group (35% vs. 14%; P = 0.035), but during long-term follow-up this difference diminished (38% vs. 23%; P = 0.121). In unselected patients with cirrhosis, who underwent successful endoscopic hemostasis for variceal bleeding, covered TIPS was superior to EVL + β-blocker for reduction of variceal rebleeding, but did not improve survival. TIPS was associated with higher rates of early hepatic encephalopathy. © 2015 by the American Association for the Study of Liver Diseases.

  11. Postoperative otorhinolaryngologic complications in transnasal endoscopic surgery to access the skull base

    Directory of Open Access Journals (Sweden)

    Ricardo Landini Lutaif Dolci

    Full Text Available Abstract Introduction: The large increase in the number of transnasal endoscopic skull base surgeries is a consequence of greater knowledge of the anatomic region, the development of specific materials and instruments, and especially the use of the nasoseptal flap as a barrier between the sinus tract (contaminated cavity and the subarachnoid space (sterile area, reducing the high risk of contamination. Objective: To assess the otorhinolaryngologic complications in patients undergoing endoscopic surgery of the skull base, in which a nasoseptal flap was used. Methods: This was a retrospective study that included patients who underwent endoscopic skull base surgery with creation of a nasoseptal flap, assessing for the presence of the following post-surgical complications: cerebrospinal fluid leak, meningitis, mucocele formation, nasal synechia, septal perforation (prior to posterior septectomy, internal nasal valve failure, epistaxis, and olfactory alterations. Results: The study assessed 41 patients undergoing surgery. Of these, 35 had pituitary adenomas (macro- or micro-adenomas; sellar and suprasellar extension, three had meningiomas (two tuberculum sellae and one olfactory groove, two had craniopharyngiomas, and one had an intracranial abscess. The complications were cerebrospinal fluid leak (three patients; 7.3%, meningitis (three patients; 7.3%, nasal fossa synechia (eight patients; 19.5%, internal nasal valve failure (six patients; 14.6%, and complaints of worsening of the sense of smell (16 patients; 39%. The olfactory test showed anosmia or hyposmia in ten patients (24.3%. No patient had mucocele, epistaxis, or septal perforation. Conclusion: The use of the nasoseptal flap has revolutionized endoscopic skull base surgery, making the procedures more effective and with lower morbidity compared to the traditional route. However, although mainly transient nasal morbidities were observed, in some cases, permanent hyposmia and anosmia resulted

    External dacryocystorhinostomy (DCR) is the method of choice to treat nasolacrimal duct (NLD) obstruction and the other approaches are compared with it, with a failure rate of 4% to 13%. The current study aimed to assess the causes of failure in external DCR by postoperative endoscopic and pathological evaluation. The current retrospective cross sectional study followed-up113 patients with external DCR and silicone intubation for three months. Silicone tubes were removed after the third months. Failure was confirmed based on the clinical findings and irrigation test. Paranasal sinus computed tomography (CT) scanning, and endoscopic and pathological evaluations were performed in the failed cases. Totally, 113 patients underwent external DCR. The patients included 71 females and 42 males. The mean age of the patients was 55.91 years; ranged from 18 to 86. Epiphora was the most common complaint before surgery (90.3%). Clinically, epiphora continued in 17 cases (15%), of which 94.11% had at least one sinus CT abnormality and 82.35% had at least one endoscopic abnormality. The most common endoscopic findings were deviated septum (70.6%), scar tissue (52.94%), concha bullosa (46.9%), septal adhesion (47.05%), enlarged middle turbinate (41.2%), and sump syndrome (11.7%). The failure was significantly associated with the chronicity of the initial symptoms (P-value=0.00). Pathologically, there were significant relationship amongst the failure rate, scar formation, and allergic rhinitis (P-values =0.00 and <0.05, respectively). Preoperative endonasal evaluation and consultation with an otolaryngologist can improve surgical outcomes and help to have a better conscious to intranasal abnormalities before external DCR surgery.

    Full Text Available Purpose: We evaluated the effectiveness of combining behavioral therapy, pharmacologic therapy and endoscopic hydrodistension for treating painful bladder syndrome / interstitial cystitis (PBS/IC. Materials and Methods: Twenty-five patients with PBS/IC were prospectively enrolled in a pilot multimodal behavioral, pharmacologic and endoscopic treatment protocol. Behavioral modification included diet recommendations, fluid restriction to 64 oz. /day, progressive timed voiding and Kegel exercises. Oral pharmacologic therapy consisted of daily doses of macrodantin 100 mg, hydroxyzine 10-20 mg and urised 4 tablets. Patients underwent endoscopic bladder hydrodistention under anesthesia at least 2 weeks after protocol enrollment. Behavioral and pharmacological treatments were continued after the hydrodistention. O'Leary-Sant questionnaire scores were recorded before starting the protocol, after pharmacologic/behavioral therapy, 2 months post-hydrodistension, and at scheduled follow-up. Results: Eighteen patients (72% completed the pilot multimodal treatment protocol and were followed for a mean of 10.2 months. All patients were female with a median age of 36.3 years and had mean bladder capacity under anesthesia of 836 milliliters. Mean O'Leary-Sant symptom index scores for baseline symptoms, after behavioral/pharmacologic treatment, post-hydrodistension and during follow up were 12.5, 8.6, 7.0, and 6.7 (p < 0.05. Mean O'Leary-Sant problem index scores for baseline, after behavioral/pharmacologic treatment, post-hydrodistention and during follow up were 12.7, 8.9, 6.7, and 7.7 (p < 0.05. Conclusion: Our pilot multimodal protocol of behavioral modification, pharmacologic therapy and endoscopic hydrodistention demonstrated a significant progressive improvement in PBS/IC quality of life scores, compared to a pre-treatment baseline. These results should be validated in a larger, placebo controlled trial.

    Full Text Available Objective To assess the curative effect of endoscopic resection in patients with non-ampullary descending duodenal tubulovillous adenoma. Methods The clinical data of 9 patients with non-ampullary descending duodenal tubulovillous adenoma from Jan. 2004 to Dec. 2012 in the Department of Endoscopy of General Hospital of Shenyang Command were retrospectively reviewed. All patients were diagnosed with endoscopy, ultrasound endoscopy and preoperative pathology, and all of them underwent endoscopic dissection. Pathological examination and follow-up were carried out after operation. Results Nine patients, including 4 men and 5 women aged 45-78 (59.6±11.5 years old were involved. Tubulovillous adenomas were found in descending duodenum of all patients, with the size of 1.8 to 2.5cm, with a mean of 2.03±0.24cm. Endoscopic resection (EMR was used in all patients successfully. No complication was found during operation and after operation. Postoperative pathology confirmed that all the tumors were tubulovillous adenomas. Low-grade intraepithelial neoplasia was found in 4 cases, and high-grade in 5 cases. Mucosal focal carcinoma was confirmed in one case, without involvement of muscularis mucosae. The position emission tomography (PET showed no abnormal radionuclide accumulation. There were no hemorrhage or death during and after the operation. The average follow-up time was 6-58 (25.6±16.4 months. Metastases and recurrence had not been found. Conclusion Endoscopic mucosal resection is a safe, adequate method for non-ampullary descending duodenal tubulovillous adenomas. DOI: 10.11855/j.issn.0577-7402.2013.11.012

    Duodenal endoscopic resection is the most difficult type of endoscopic treatment in the gastrointestinal tract (GI) and is technically challenging because of anatomical specificities. In addition to these technical difficulties, this procedure is associated with a significantly higher rate of complication than endoscopic treatment in other parts of the GI tract. Postoperative delayed perforation and bleeding are hazardous complications, and emergency surgical intervention is sometimes required. Therefore, it is urgently necessary to establish a management protocol for preventing serious complications. For instance, the prophylactic closure of large mucosal defects after endoscopic resection may reduce the risk of hazardous complications. However, the size of mucosal defects after endoscopic submucosal dissection (ESD) is relatively large compared with the size after endoscopic mucosal resection, making it impossible to achieve complete closure using only conventional clips. The over-the-scope clip and polyglycolic acid sheets with fibrin gel make it possible to close large mucosal defects after duodenal ESD. In addition to the combination of laparoscopic surgery and endoscopic resection, endoscopic full-thickness resection holds therapeutic potential for difficult duodenal lesions and may overcome the disadvantages of endoscopic resection in the near future. This review aims to summarize the complications and closure techniques of large mucosal defects and to highlight some directions for management after duodenal endoscopic treatment.

    By analyzing seroma volume changes in the patients who underwent Partial breast radiation therapy after breast conserving surgery, we try to contribute to the improvement of radiotherapy effect. Enrolled 20 patients who underwent partial breast radiation therapy by ViewRay MRIdian System were subject. After seeking for the size of the removed sample in the patients during surgery and obtained seroma volume changes on a weekly basis. On the Basis of acquired volume, it was compared with age, term from start of the first treatment after surgery, BMI (body mass index) and the extracted sample size during surgery. And using the ViewRay MRIdian RTP System, the figure was analyzed by PTV(=seroma volume + margin) to obtain a specific volume of the Partial breast radiation therapy. The changes of seroma volume from MR simulation to the first treatment (a week) is 0~5% in 8, 5~10% in 3, 10 to 15% in 2, and 20% or more in 5 people. Two patients(A, B patient) among subjects showed the biggest change. The A patient's 100% of the prescribed dose volume is 213.08 cc, PTV is 181.93 cc, seroma volume is 15.3 cc in initial plan. However, while seroma volume decreased 65.36% to 5.3 cc, 100% of the prescribed dose volume was reduced to 3.4% to 102.43 cc and PTV also did 43.6% to 102.54 cc. In the case of the B patient, seroma volume decreased 42.57% from 20.2 cc to 11.6 cc. Because of that, 100% of the prescribed dose volume decreased 8.1% and PTV also did to 40%. As the period between the first therapy and surgery is shorter, the patient is elder and the size of sample is smaller than 100 cc, the change grow bigger. It is desirable to establish an adaptive plan according to each patient's changes of seroma volume through continuous observation. Because partial breast patients is more sensitive than WBRT patients about dose conformity in accordance with the volume change.

    Chronic granulomatous disease (CGD) is a rare inherited disorder in which phagocytes are unable to eradicate pathogens because of a deficit of nicotinamide adenine dinucleotide phosphate oxidase. Among CGD patients, ∼ 30% to 50% develop severe gastrointestinal tract symptoms. Although characteristic histologic findings of CGD-associated colitis have been reported, information on endoscopic features remained vague. A total of 8 male patients with CGD (ages 2-23 years) from 2 Japanese institutions underwent colonoscopy for the evaluation of their fever, diarrhea, bloody stool, and abdominal pain. The endoscopic and histologic findings were retrospectively reviewed. The endoscopic findings of CGD-associated colitis appeared varied. Notably, brownish dots over a yellowish edematous mucosa were observed in 3 of the 8 patients. Prominent pigment-laden macrophages were noted histologically on the mucosa. Although nonspecific endoscopic findings of CGD-associated colitis have been reported before, our observation of brownish dots spread across a yellowish edematous mucosa, termed "leopard sign," could be a unique feature of this condition.

    Pleural disease remains a commonly encountered clinical problem for both physician and surgeon. This study describes a new way to better diagnose and treat pleural diseases (hemothorax, empyema, and pleural effusion) using an electronic endoscope (gastroscope or bronchoscope). We conducted a retrospective study of the use of an electronic endoscope in the treatment and diagnosis of pleural diseases. From November 2006 to February 2008, a total of 17 patients (3 women, 14 men; mean age = 41.8 years; range = 18-62 years) underwent procedures for thoracic empyema (13 patients), traumatic clotted hemothorax (3 patients), and undiagnosed pleural effusion (1 patient). The electronic endoscope was inserted via the thoracic drainage tube for the treatment or diagnosis of pleural diseases after regular treatments, including thoracentesis, tube thoracostomy, and biopsy, failed. All patients were cured and discharged from hospital and were followed up for 6 months. The patients recovered well and there was no recurrence. The technique of inserting an electronic endoscope into the thoracic drainage tube for diagnosis and treatment of pleural diseases is simple, effective, minimally invasive, and cost-effective.

    Full Text Available ABSTRACT We present the case of a 31-year-old patient with toxic anterior segment syndrome (TASS that developed after undergoing deep anterior lamellar keratoplasty (DALK. She had keratoconus, and despite wearing hard contact lenses for many years in the left eye, her vision had deteriorated; therefore, DALK was performed on this eye. The preoperative visual acuity (VA was finger counting at 3 m. Routine DALK was performed using the "big-bubble" technique. The corneal entry incision was hydrated at the end of the surgery, which was terminated by air injection into the anterior chamber. On postoperative day 1, VA was at the level of hand movements, and the cornea was edematous. Topical high-dose dexamethasone and oral steroids were initiated considering the diagnosis of TASS. Subsequently, the patient's VA increased, and the corneal edema decreased. We believe that the use of re-sterilized cannulas may have been the likely cause of TASS. Although DALK can be performed without interfering with the anterior chamber, one should keep in mind that TASS may occur in response to the solution used to hydrate the incision site and the air injected into the anterior chamber.

    As nutrition support for head and neck cancer patients who receive chemoradiotherapy (CRT) and whose oral cavity or pharynx is exposed to radiation, we perform percutaneous endoscopic gastrostomy (PEG) tube placement. We examined 235 patients who underwent PEG in our division between January 2003 and December 2009. For 64% of them, the purpose of performing PEG was nutrition support for CRT, of whom 74% actually used the tube. However, the situation varied according to the primary sites of patients. Forty-four percent of laryngeal cancer patients who underwent PEG actually used the tube, which was a significantly lower rate than others. Also, 81% of them removed the PEG tube within one year. These findings suggest that PEG-tube placement for nutrition support is not indispensable for all CRT cases. Therefore, we recommend performing PEG for oral, oropharyngeal, and hypopharyngeal cancer patients. (author)

    We report three cases of abdominal wall necrotizing fasciitis that occurred as a result of leakage from displaced percutaneous endoscopic gastrostomy tubes. This is the first report of such a series. Patients underwent extensive operative excisions of their abdominal walls down to their posterior fascia. All patients tolerated their initial surgery, however, two patients ultimately expired from respiratory complications. The surviving patient underwent multiple repeat debridements and reconstructive abdominal wall surgery. We review the epidemiology of patients at risk for this complication and discuss its presentation, as well as the appropriate workup and management. We also address the issues of closure of large abdominal wall defects and future alimentation in this patient group. Finally, abdominal wall necrotizing faciitis from gastrostomy tube leakage is a devastating complication, and the development of preventative strategies for patients at risk is of paramount importance.

    Full Text Available Oriental cholangiohepatitis (OCH is a disease characterized by intrabiliary pigment stone formation, resulting in recurrent bouts of cholangitis. OCH is found mostly in Southeast Asia but it is occasionally recognized in Western societies. OCH etiology is largely unknown. We report our experience with a patient who presented with acute cholecystitis. Following laparoscopic cholecystectomy, she developed acute cholangitis due to multiple biliary tree stones. She underwent ERCP to clear the stones from common bile duct. For the intrahepatic stones, she underwent novel hybrid percutaneous endoscopic technique. The procedure resulted in complete clearance of biliary tree stones and resolution of her symptoms. The aim of this case is to increase awareness of this disease when patients from endemic areas present with biliary stones.

    To identify independent factors that may predict vesicoureteral reflux (VUR) resolution after endoscopic treatment using dextranomer/hyaluronic acid copolymer (Deflux) in children free of anatomical anomalies. A retrospective study was conducted in our pediatric referral center from 1998 to 2011 on children with primary VUR who underwent endoscopic injection of Deflux with or without concomitant autologous blood injection (called HABIT or HIT, respectively). Children with secondary VUR or incomplete records were excluded from the study. Potential factors were divided into three categories including preoperative, intraoperative and postoperative. Success was defined as no sign of VUR on postoperative voiding cystourethrogram. Univariate and multivariate logistic regression models were constructed to identify independent factors that may predict success. Odds ratio (OR) and 95 % confidence interval (95 % CI) for prediction of success were estimated for each factor. From 485 children received Deflux injection, a total of 372 with a mean age of 3.10 years (ranged from 6 months to 12 years) were included in the study and endoscopic management was successful in 322 (86.6 %) of them. Of the patients, 185 (49.7 %) underwent HIT and 187 (50.3 %) underwent HABIT technique. On univariate analysis, VUR grade from preoperative category (OR = 4.79, 95 % CI = 2.22-10.30, p = 0.000), operation technique (OR = 0.33, 95 % CI = 0.17-0.64, p = 0.001) and presence of mound on postoperative sonography (OR = 0.06, 95 % CI = 0.02-0.16, p = 0.000) were associated with success. On multivariate analysis, preoperative VUR grade (OR = 4.85, 95 % CI = 2.49-8.96, p = 0.000) and identification of mound on postoperative sonography (OR = 0.07, 95 % CI = 0.01-0.18, p = 0.000) remained as independent success predictors. Based on this study, successful VUR correction after the endoscopic injection of Deflux can be predicted with respect to preoperative VUR grade and presence of mound after operation.

    Full Text Available ABSTRACT OBJECTIVES: To evaluate through the visual analog scale (VAS the pain in patients undergoing total knee replacement (TKR with different pressures of the pneumatic tourniquet. METHODS: An observational, randomized, descriptive study on an analytical basis, with 60 patients who underwent TKR, divided into two groups, which were matched: a group where TKR was performed with tourniquet pressures of 350 mmHg (standard and the other with systolic blood pressure plus 100 mmHg (P + 100. These patients had their pain assessed by VAS at 48 h, and at the 5th and 15th days after procedure. Secondarily, the following were also measured: range of motion (ROM, complications, and blood drainage volume in each group; the data were subjected to statistical analysis. RESULTS: After data analysis, there was no statistical difference regarding the incidence of complications (p = 0.612, ROM (p = 0.202, bleeding after 24 and 48 h (p = 0.432 and p = 0.254 or in relation to VAS. No correlation was observed between time of ischemia compared to VAS and bleeding. CONCLUSIONS: The use of the pneumatic tourniquet pressure at 350 mmHg or systolic blood pressure plus 100 mmHg did not influence the pain, blood loss, ROM, and complications. Therefore the pressures at these levels are safe and do not change the surgery outcomes; the time of ischemia must be closely observed to avoid major complications.

    There are increasingly more patients seeking minimally invasive procedures, which have become more effective and safer in reducing the signs of facial aging. This study included 40 female adult patients who voluntarily underwent selected minimally invasive procedures (filling with hyaluronic acid and botulinum toxin injection) for facial rejuvenation. All patients were followed for a period of 6 months. They were evaluated with the use of questionnaires, a quality-of-life questionnaire (DLQI), the self-esteem scale of Rosenberg (EPM/Rosenberg), and a pain scale. The minimally invasive procedures resulted in improvement in quality of life and self-esteem, which were stronger the first 3 months after the procedures but remained at a higher level than that before treatment, even after 6 months. Hyaluronic acid with lidocaine in the formula is more comfortable for the patient as it makes the injection less painful.

    Basal and squamous cell carcinomas are the most common malignant cutaneous lesions affecting the nose. With the rising incidence of skin cancers, plastic surgeons increasingly face nasal reconstruction challenges. Although multiple options exist, optimal results are obtained when "like is used to repair like". We aimed to introduce a simple algorithm for the reconstruction of nasal defects with local flaps, realizing that there is always more than one option for reconstruction. We retrospectively reviewed 163 patients who underwent nasal reconstruction after excision of non-melanoma skin cancer between March 2011 and April 2014. We analyzed the location of the defects and correlated them with the techniques used to reconstruct them. There were 66 males and 97 females (age, 21-98 years). Basal cell carcinoma was diagnosed in 121 patients and squamous cell carcinoma in 42. After tumor excision, all the defects were immediately closed by either primary closure or local flap options such as Limberg, Miter, glabellar, bilobed, nasolabial, V-Y advancement, and forehead flaps. Obtaining tumor-free borders and a pleasing aesthetic result are major concerns in nasal reconstruction. Defect reconstruction and cosmesis are as important as rapid recovery and quick return to normal daily activities, and these should be considered before performing any procedure, particularly in elderly patients.

    We investigated the risk factor of perioperative asthmatic attack and effectiveness of preventing treatment for asthmatic attack before operation. We performed retrospective chart review of one hundred eleven patients with asthma underwent general anesthesia and surgical intervention from January 2006 to October 2007 in our hospital. The rate of perioperative asthmatic attack were as follows; 10.2% (5 in 49 cases) in no pretreatment group, 7.5% (3 in 40 cases) in any pretreatments except for systemic steroid, and 4.5% (1 in 22 cases) in systemic steroid pretreatment group. Neither preoperative asthma severity nor duration from the last attack had significant relevancy to perioperative attack rate. The otolaryngological surgery, especially those have nasal polyp and oral surgery had high perioperative asthma attack rate, although there was no significant difference. We recommend the systemic steroid pretreatment for asthmatic patients, especially when they have known risk factor such as administration of the systemic steroid within 6 months, or possibly new risk factor such as nasal polyp, otolaryngological and oral surgery.

    Full Text Available Background. Hypothermia in the surgical patients can be the consequence of long duration of surgical intervention, general anesthesia and low temperature in operating room. Postoperative hypothermia contributes to a number of postoperative complications such as arrhythmia, myocardial ischemia, hypertension, bleeding, wound infection, coagulopathy, prolonged effect of muscle relaxants. External heating procedures are used to prevent this condition, but some investigations reported that infusion of aminoacids during surgery can induce thermogenesis and prevent postoperative hypothermia. Case report. We reported two males who underwent major colorectal surgery for rectal carcinoma. One patient received Aminosol 15% solution, 125 ml/h, while the other did not. The esophageal temperatures in both cases were measured every 30 minutes during the operation and 60 minutes after in Intensive Care Unit. We were monitoring blood pressure, heart rate, ECG, and shivering. Patient who received aminoacids showed ameliorated postoperative hypothermia without hypertension, arrhythmia, or shivering, while the other showed all symptoms mentioned above. Conclusion. According to literature data, as well as our findings, we can conclude that intraoperative intravenous treatment with amino acid solution ameliorates postoperative hypothermia along with its complications. .

    To determine the prevalence and spontaneous resolution of congenital hydrocele diagnosed in male neonates who underwent circumcision at our centre. All male neonates presented for circumcision at the University of Benin Teaching Hospital, Benin City, Nigeria between January 2002 and December 2006 were examined for the presence of hydrocele. Those diagnosed with this condition were recruited and followed up in a surgical outpatient clinic for 2 years. The number of cases of spontaneous resolution and age at which this occurred were documented on a structured pro forma. A total of 2715 neonates were circumcised and 128 (4.7%) were diagnosed with 163 cases of hydrocele, while 27 cases in 25 (0.9%) children failed to resolve at the age of 2 years. Neonatal hydrocele was bilateral in 112 (68.7%), and there were 20 (12.3%) right and 31 (19.0%) left. Among those with hydrocele, 28.1% were delivered preterm and resolution was spontaneous in many of them, with no observed significant statistical difference to those delivered full term (P=0.4740). Of the 163 hydrocele cases, 136 (83.4%) resolved spontaneously by age 18 months with peak resolution at 4-6 months. No spontaneous resolution occurred after 18 months and no hydrocele-related complication occurred during follow up. Neonates with congenital hydrocele should be observed for spontaneous resolution for at least 18 months before being subjected to surgery.

    To describe the psychological stress and quality of life experienced by women who underwent fertility treatment in Taiwan. Cross-sectional, correlational study. Recruitment was conducted and questionnaires administered at a reproductive medicine center in Chiayi City, Taiwan. Informed consent to participate was obtained from 126 women who sought fertility treatment at the center. The Chinese Fertility Problem Inventory and Fertility Quality of Life scale were used to measure participants' levels of fertility-related stress and fertility-related quality of life. Descriptive statistics, correlation, and regression analysis were used. Overall, participants reported low levels of fertility-related stress and fertility-related quality of life; however, they had relatively high levels of stress related to need for parenthood. Women who were older, had greater body mass indexes, and consumed coffee regularly had lower fertility-related quality of life. Social and relationship concerns and stress related to need for parenthood were significant predictors of low fertility-related quality of life. In a culture in which childbearing is generally an expectation and an important part of family life, women who experience infertility are at risk to experience fertility-related stress. Social support and family consultation might be offered to improve women's fertility-related quality of life.

    Background and study aims  Adenomas of the duodenum and ampulla are uncommon. For lesions ≤ 20 mm in size and confined to the papillary mound, endoscopic resection is well supported by systematic study. However, for large laterally spreading lesions of the duodenum or papilla (LSL-D/P), surgery is often performed despite substantial associated morbidity and mortality. We aimed to compare actual endoscopic outcomes of such lesions and costs with those predicted for surgery using validated prediction tools. Patients and methods  Patients who underwent endoscopic resection of LSL-D/P were analyzed. Two surgeons assigned the hypothetical surgical management. The National Surgical Quality Improvement Program (NSQIP), and the Portsmouth Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (P-POSSUM) were used to predict morbidity, mortality, and length of hospital stay. Actual endoscopic and hypothetical surgical outcomes and costs were compared. Results  A total of 102 lesions were evaluated (mean age of patients 69 years, 52 % male, mean lesion size 40 mm). Complete endoscopic resection was achieved in 93.1 % at the index procedure. Endoscopic adverse events occurred in 18.6 %. Recurrence at first surveillance endoscopy was seen in 17.7 %. For patients with ≥ 2 surveillance endoscopies (n = 55), 90 % were clear of disease and considered cured (median follow-up 27 months). Compared with hypothetical surgical resection, endoscopic resection had less morbidity (18 % vs. 31 %; P  = 0.001) and shorter hospital stay (median 1 vs. 4.75 days; P  < 0.001), and was less costly than surgery (mean $ 11 093 vs. $ 19 358; P  < 0.001). Conclusion  In experienced centers, even extensive LSL-D/P can be managed endoscopically with favorable morbidity and mortality profiles, and reduced costs, compared with surgery. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Objective To study the clinical manifestations, pathologic features, diagnosis, treatment and prognosis of primary synovial sarcoma in the anterior mediastinum. Methods A case of primary synovial sarcoma in the anterior mediastinum was reported. Clinical features, imaging manifestations, pathology features and therapeutic effect were analysed and the relevant literature was reviewed. Results A 48-year-male patient was admitted with complaint of right chest pain for 4 days. Chest computerized tomography revealed a large mass located at the right anterior mediastinum, and it was primarily diagnosed as invasive thymoma. Pathological examination by CT-guided percutaneous needle biopsy manifested that, under microscope, the tumor cells were short and spindle in shape forming a nest structure, suggested it was a thymoma. The patient then underwent resection of thymoma with removal of fat and connective tissue in the anterior mediastinum. During the operation the size of the tumor was 15cm×15cm×10cm, being located at the anterior mediastinum, and it tended to bleed. The diagnosis of primary monophasic synovial sarcoma in the mediastinum was confirmed by postoperative/pathology examination. Immunohistochemistry staining showed that the tumor cells were positive for the markers Bcl-2 and EMA, but negative for the markers CK (pan and S100. The patient suffered from local recurrence with metastases to lung 4 months after surgery. The patient received 2 chemotherapeutic courses with ifosfamide, epirubicin and cisplatin. He died 6 months after surgery. Conclusion Primary synovial sarcoma in the anterior mediastinum is an extremely rare and highly malignant tumor with poor prognosis. The diagnosis depends on the pathological features, immunohistochemistry and RT-PCR. Radical resection combined with comprehensive treatment may improve the survival rate.

    Endoscopic third ventriculostomy (ETV) is an alternative to ventriculoperitoneal shunting for hydrocephalus treatment. Choice of treatment options raises questions about which patients are likely to benefit from ETV. The authors performed a population-based analysis using an administrative claims database, examining current practice and outcomes for pediatric patients in the US. The authors queried the MarketScan (Truven Health Analytics) database for Current Procedural Terminology codes corresponding to ETV and ventriculoperitoneal shunting from 2003 to 2011; they included patients 19 years or younger and extracted data from initial and subsequent hospitalizations. Hydrocephalus etiology was classified with ICD-9-CM coding. ETV failure was defined as any subsequent ETV or shunt procedure. Five hundred one patients underwent ETV. Of these, 46% were female. The mean age was 8.7 ± 6.4 years (± SD). The mean follow-up was 1.9 ± 1.8 years. Etiology of hydrocephalus was primarily tumor (41.7%) and congenital/aqueductal stenosis (24.4%). ETV was successful in 354 patients (71%). The mean time to failure was 109.9 ± 233 days. Of the 147 patients with ETV failure, 35 (24%) underwent repeat ETV and 112 (76%) had shunt placement. Patients in age groups 0 to HR 2.9, p = 0.05; and HR 2.3, p = 0.001, respectively). History of prior shunt was associated with higher risk of failure (HR 2.5, p < 0.001). There were no significant associations between hydrocephalus etiology and risk of failure. A second wave of failures occurred at 2.5-3.5 years postoperative in tumor and congenital/aqueductal stenosis patients; this was not observed in other etiology groups. This study represents a cross-section of nationwide ETV practice over 9 years. ETV success was more likely among children 1 year and older and those with no history of prior shunt.

    Achalasia cardia (AC) is a motility disorder, characterized by impaired lower esophageal sphincter relaxation and absence of esophageal peristalsis. AC is rare in children with unclear optimum management strategies. Per oral endoscopic myotomy (POEM) is a novel technique for management of achalasia with encouraging results in adult patients. The efficacy and safety of POEM is not known for pediatric AC. The aim of our study was to evaluate the safety and efficacy of POEM in children with achalasia cardia. The data of all children (< 18 years) who underwent POEM at our center was retrospectively analysed. Symptoms were analysed using a validated score (Eckardt score) at regular predefined intervals. Objective parameters including high-resolution manometry, timed barium swallow and esophagogastroduodenoscopy were assessed before the procedure and at 1-year follow-up. Clinical success was defined as an Eckardt score ≤ 3. A total of 15 children underwent POEM during the specified period. Ten out of 15 (10/15) completed 1-year follow-up. Median operative time was 100 (38-240) minutes. Mean pre and post procedure LES pressure were 36.64 ± 11.08 mmHg and 15.65 ± 5.73 mmHg, respectively ( P = 0.001). Mean Eckardt score before and after the POEM was 7.32 ± 1.42 and 1.74 ± 0.67, respectively ( P = 0.001). Mean percentage improvement in barium emptying at 5 minutes was 63.70 ± 4.46%. All children had complete resolution of symptoms at 1 year. Median weight gain of children at 1 year was 0.65 kg (range, 0.0-4.6). POEM is safe and effective for children and adolescents with achalasia. Future trials with larger sample size are warranted to establish its efficacy in pediatric AC.

    Full Text Available Abstract Background To conduct a meta-analysis to determine the relative merits of robotic thyroidectomy (RT and endoscopic thyroidectomy (ET. Methods A literature search was performed to identify comparative studies reporting peri-operative outcomes for RT and ET. Pooled odds ratios (ORs and weighted mean differences (WMDs with 95% confidence interval (95% CI were calculated using either a fixed-effects or a random-effects model. Results Six studies matched the selection criteria, which reported on 2048 subjects, of whom 978 underwent RT and 1070 underwent ET. Comparing the outcomes of RT with ET, this meta-analysis indicated that RT was associated with more complications (WMD = 1.51, 95% CI 1.18 to 1.94 and greater amount of drainage fluid (WMD = 17.10, 95% CI 5.69 to 28.51. Meanwhile, operating time (WMD = 1.50, 95% CI −39.59 to 42.58, conversion (WMD = 0.63, 95% CI 0.07 to 6.17, post-operative hospital stay (WMD = −0.05; 95% CI −0.18 to 0.08, and the number of lymph nodes harvested (WMD = 0.62, 95% CI −0.29 to 1.53 were similar for both procedures. Conclusion The results of this meta-analysis indicated that RT is associated with an increased risk of complications and a greater amount of drainage fluid. Therefore, RT does not appear to have any advantage over ET. Further studies are required to confirm these results.

    Digital and mobile device technology in healthcare is a growing market. The introduction of the endoscope-i, the world's first endoscopic mobile imaging system, allows the acquisition of high definition images of the ear, nose and throat (ENT). The system combines the e-i Pro camera app with a bespoke engineered endoscope-i adaptor which fits securely onto the iPhone or iPod touch. Endoscopic examination forms a salient aspect of the ENT work-up. The endoscope-i therefore provides a mobile and compact alternative to the existing bulky endoscopic systems currently in use which often restrict the clinician to the clinic setting. Areas covered: This article gives a detailed overview of the endoscope-i system together with its applications. A review and comparison of alternative devices on the market offering smartphone adapted endoscopic viewing systems is also presented. Expert commentary: The endoscope-i fulfils unmet needs by providing a compact, highly portable, simple to use endoscopic viewing system which is cost-effective and which makes use of smartphone technology most clinicians have in their pocket. The system allows real-time feedback to the patient and has the potential to transform the way that healthcare is delivered in ENT as well as having applications further afield.

    Raynaud's disease is a disorder that is characterized by attacks of pain, cyanosis, redness, and numbness in the upper extremities caused by vasospasm of digital arteries due to cold or emotional stress. We aimed at demonstrating our experiences with endoscopic thoracic sympathectomy (ETS) in the treatment of Raynaud's disease. From 48 patients who underwent ETS for various reasons at our department between January 2014 and January 2015, we reviewed 9 patients with Raynaud's disease (18.7%) with respect to their demographic characteristics such as gender and age, postoperative complications, short-term results, side effects, recurrence of symptoms, and long-terms results. The symptoms and findings reappeared and the number and dosage of the drugs used returned to their preoperative levels in 66.6% of the patients at month 6, and in all patients except 1 at the end of the 1st year. ETS should be considered an ultimate choice for patients with Raynaud's disease who have treatment-resistant severe symptoms and serious complications, disturbed social and daily lives, and impaired quality of life, and all patients should be properly informed before the surgery about the possibility of a high rate of recurrence.

    To describe a simple modification of fashioning the mucosal flap for endonasal endoscopic dacryocystorhinostomy (EES-DCR) in Asians and investigate its efficacy. A total of 120 patients with unilateral primary chronic dacryocystitis (PCD) were randomized into two groups: the new shaped nasal mucosal flap group (group A) and the removed nasal mucosal flap group (group B). All patients underwent standard EES-DCR. Patients in group A were performed a new shaped nasal mucosal flap covering the bared bone around the opened sac and those in group B was removed the nasal mucosal flap uncovering the bared bone. Patients were followed up for one year. The occurrence of granulation tissue, the proliferation of scar tissue and success rate of EES-DCR was compared. In the present study, complete postoperative data were acquired from 54 patients in group A and from 57 patients in group B. During process of review, the occurrence of granulation tissue was at the ostium margins account for 15% (8/54) in group A and 39% (22/57) in group B (Pbared bone around the opened sac and reduce formation of granulation tissue, lessen the risk of scar tissue formation and closure of ostium, thus improve the success rate of EES-DCR in Asians.

    To analyze the efficacy of FESS in patients with recurrent nasal polyposis in terms of relief of nasal obstruction, improvement in sense of smell and to assess recurrence of disease. Study Design: Descriptive case series. Materials and Method: All patients who underwent FESS (Functional endoscopic sinus surgery) for recurrent nasal polyposis from June 2008 to June 2010 with an average follow up of 06 month were included. Clinical symptoms including nasal obstruction and olfactory disturbance were evaluated using VAS system pre and postoperatively. Preoperatively computed tomography scan was done in all cases to assess extent of disease and surgical anatomy. Results: Following FESS 96% of total patients demonstrated statistically significant improvement in relieving nasal obstruction after 6 months follow up, however improvement in sense of smell was seen in 44% of patients. Recurrence was seen in only 3 (6%) cases at 3rd and 6th month follow up. Conclusion: Functional endoscopy sinus surgery of recurrent nasal polyposis is an effective method of surgery with significant improvement of symptom of nasal obstruction and olfaction with minimal recurrence at 6 month in our centre. Our results were compatible with results attained internationally. (author)
