    The gasless, transaxillary endoscopic thyroidectomy (GTET) and minimally invasive video-assisted thyroidectomy (VAT) are both well-recognized endoscopic thyroid procedures, but how their postoperative outcomes are compared remains unclear. The present study was designed to compare surgical morbidities/complications and scar appearance between GTET and VAT at our institution. Of the 141 patients eligible for endoscopic thyroidectomy, 96 (68.1 %) underwent GTET and 45 (31.9 %) underwent VAT. Patient demographics, indications, operative findings, pain scores on days 0 and 1, and surgical morbidities were compared between the two groups. At 6 months after surgery, all patients were asked about their satisfaction on the cosmetic result by giving a score (Patient Satisfaction Score or PSS) and their scar appearance was assessed by the 11 domains in the Patient and Observer Scar Assessment Scale (POSAS). GTET was associated with a significantly longer operating time (84 vs. 148 min, p = 0.005), higher pain scores on days 0 and 1 (2.9 vs. 2.3, p = 0.042 and 2.2 vs. 1.7, p = 0.033, respectively), overall recurrent laryngeal nerve (RLN) injury (6.3 vs. 0 %, p = 0.043), and overall morbidity rates (12.5 vs. 2.2 %, p = 0.049) than VAT. The actual individual score for the 11 domains in POSAS and for PSS remained similar between the two groups. They remained similar even when patients with morbidity were excluded. GTET was a technically more challenging procedure and was associated with longer hospital stay, longer operating time, more immediate pain, and increased overall RLN injury and morbidity than VAT. The 6-month POSAS and PSS were similar between the two procedures.

    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

    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.

    After nearly a century of performing a thyroid-ectomy essentially the way it was described by Theodore Kocher in the nineteenth century, the technique has suddenly and rapidly evolved. It can now be accomplished endoscopically in many patients who therefore benefit from the reduced dissection and smaller incisions associated with the approach. While many of the cosmetic, quality of life, and functional improvements have now been documented, an improved understanding of the procedure and the appropriate indications for its application will continue to develop even as the technique itself evolves, and as new approaches emerge.

    To develop a new endoscopic approach to the correction of a myelomeningocele-like defect in fetal sheep. The fetuses of 9 pregnant ewes, with an average gestational age of 115 days, were subjected to a 3.0 x 2.0 cm removal of the skin over the lumbar spine, performed through hysterotomy. The uterus was closed, and three 5-mm endoscopic cannulas, without valve mechanisms, were inserted. In the pilot phase (2 animals), we initially worked exclusively in the amniotic fluid space. In the study phase, we partially withdrew the fetus from the amniotic fluid to completely expose its back. By simply allowing air to enter the amniotic cavity (without gas injection), a working space was created using a uterine lift device. The skin around the defect was dissected, and a biosynthetic cellulose material was applied to cover the area. A continuous suture of the skin was performed to completely hide the material. The combined air/fluid space allowed the skin to be successfully closed in 6 out of 7 cases in the study phase. All fetuses were alive at the end of the procedures. Time to complete the endoscopic part of the procedure fell from 3 to 1 h by the end of this series. Premature birth occurred in 2 of the 4 cases allowed to continue with the pregnancy. A new gasless fetoscopic surgery technique was developed as an alternative to current techniques used for fetal endoscopic surgery. (c) 2008 S. Karger AG, Basel.

    Natural orifice translumenal endoscopic surgery (NOTES(®); American Society for Gastrointestinal Endoscopy [Oak Brook, IL] and Society of American Gastrointestinal and Endoscopic Surgeons [Los Angeles, CA]) has generated excitement among surgeons as potentially scar-free surgery. We developed this technique while taking into consideration that it could also be applied to transoral thyroid surgery. We report the case of a 35-year-old woman with a 0.5×0.5-cm papillary thyroid microcarcinoma. We implemented a modified approach for the removal of the thyroid by using a frenotomy incision of the mouth, accompanied by an endoscope system. A modified approach for the removal of the thyroid was used on the patient. The total operating time was 120 minutes, and there were no specific complications. The patient continues to be free of any diseases 12 months after the excision. Thyroidectomy can be performed by a transoral endoscope-assisted approach through a frenotomy incision of the mouth. We describe the detailed procedures for an endoscope-assisted transoral thyroidectomy using a frenotomy incision.

    Neck surgery is one of the latest applications of minimally invasive surgery. We applied a new technique for totally endoscopic thyroidectomy, the axillo-bilateral-breast approach (ABBA). This approach does not leave a scar on the neck. Between February 2005 and October 2005, 13 patients were treated by ABBA for uni- or multinodular goitres. Surgery is performed under general anaesthesia and in supine position. 5 mm bilateral skin incisions are made on the margin of the areola of nipple. They are used to insert and subcutaneously push forward a 20 cm long, 5 mm trocar to the jugular fossa. A further 5 mm incision is performed in the right axilla. The right breast trocar is the optical trocar. A Maryland clamp in axillary position and 5 mm harmonic scalpel via the left breast trocar permit a clear view of the further subfascial preparation. The caudal hyoidal muscles are longitudinally split along the linea alba. Using delicate blunt dissection, both thyroid lobes are exposed. After isthmus transection is performed, the upper thyroid pole is being mobilized. The upper pole vessels are isolated and divided close to the thyroid capsule. Preparation of the retrothyroidal area includes visualization of the recurrent laryngeal nerve. The resection is performed without bleeding with a harmonic scalpel. Via the axillary approach, with the incision being widened, a 20 mm trocar is inserted and advanced up to the thyroid lodge to remove the specimen. The average operation time was 132 minutes. No patient had to be converted to a conventional approach. Hypocalcaemia or recurrent laryngeal nerve palsy were not observed postoperatively. Our preliminary results show that the ABBA technique is a feasible, safe procedure with excellent cosmetic benefits. The small scars in the right axilla and bilateral nipple areola are almost invisible.

    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.

    The advantages of endoscopic thyroidectomy and neck dissection include reduced hyperesthesia or paresthesia in the neck and favorable cosmetic outcomes. However, endoscopic thyroidectomy with neck dissection has a long learning curve, as well as technical limitations associated with a 2-dimensional view and a reduced dexterity of movement, particularly when operating in deep and narrow spaces such as the neck area. A robotic approach has been developed to overcome these limitations, facilitating manipulation and shortening the learning curve. This system enables the surgeon to control the 3-dimensional high-definition camera, reducing physiological tremors and enabling free dexterity of movement using articulated instruments. Therefore, robotic surgery has been found to eliminate many problems encountered with conventional endoscopic techniques.Recently, robotic thyroidectomy with neck dissection via a gasless transaxillary approach was shown to yield similar oncologic outcomes as conventional open procedures, as determined by postoperative radioactive iodine scans, serum thyroglobulin concentrations, and number of retrieved cervical lymph nodes. We also found that the robotic technique was safe and feasible in thyroid cancer patients, yielding excellent cosmetic results, reduced pain, improved sensory changes and decreased postoperative voice changes and swallowing discomfort. For surgeons, the use of a robot offers a shorter operation time and the need for a shorter learning curve than conventional endoscopic thyroidectomy. Robotic thyroidectomy also causes less musculoskeletal discomfort to surgeons than open or endoscopic thyroidectomy. The advantages of robotic surgery over open or endoscopic surgery suggest that robotic thyroidectomy with neck dissection may become the preferred surgical option for patients with thyroid cancer. Further analyses of surgeons' experience, assessments of long-term outcomes, and randomized controlled trials remain important.

    Endoscopic thyroidectomy is considered appropriate for follicular neoplasms, but on occasion, it leads to unexpected complications such as seeding along the port insertion site. Only 4 cases of operative track seeding after endoscopic thyroidectomy have been reported. Furthermore, simultaneous seeding at both operative track of upper chest wall and operative bed is also very rare. We present a case of thyroid follicular adenoma seeding at both the subcutaneous tunnel of the upper chest wall and the operative bed after endoscopic thyroidectomy, with an emphasis on magnetic resonance imaging and ultrasonography with pathologic correlations.

    Full Text Available Background: Single-port unilateral axillary thyroidectomy has great potential to become a valid alternative technique for thyroid surgery. We tested the technique in a study on live animals and cadavers to evaluate the feasibility and reproducibility of the procedure. Materials and Methods: Institutional review board (IRB approval was obtained in our university by the Council of Ethics for the study in surviving animals and cadavers. Subtotal thyroidectomy using unilateral axillary single port was performed in five dogs and five cadavers. Performing incision in the axillary fossa, a disposable single port was inserted. The dissection progressed for creating a subcutaneous tunnel to the subplatysmal region; after opening the platysma muscle and separation of the strap muscles, the thyroid gland was identified. After key anatomical landmarks were identified, the dissection was started at the upper pole towards the bottom, and to the isthmus. Specimens were extracted intact through the tunnel. Clinical and laboratorial observations of the experimental study in a 15-day follow-up and intraoperative data were documented. Results: All surgeries were performed in five animals which survived 15 days without postoperative complications. In the surgeries successfully performed in five cadavers, anatomical landmarks were recognised and intraoperative dissection of recurrent nerves and parathyroid glands was performed. Mean operative time was 64 min (46-85 min in animals and 123 min (110-140 min in cadavers, with a good cosmetic outcome since the incision was situated in the axillary fold. Conclusion: The technique of single-port axillary unilateral thyroidectomy was feasible and reproducible in the cadavers and animal survival study, suggesting the procedure as an alternative to minimally invasive surgery of the neck.

    Increasing number of patients with thyroid carcinoma, especially young female patients, prefer to choose endoscopic thyroidectomy with bilateral central neck dissection (ETBC) for perfect cosmetic effects. However, the incidence of hypoparathyroidism after ETBC has not been well studied. Ninety six patients with papillary thyroid carcinoma were enrolled. All patients, including 49 ETBC and 47 open surgery patients, underwent total thyroidectomy with bilateral central neck dissection (CND). Some patients also underwent lateral neck dissection simultaneously. The incidence of hypoparathyroidism and parathyroid hormone (PTH) level were examined. Patients in the open surgery group had more advanced lesions, with larger tumor (p = 0.000), older age (p = 0.000), and more serious local involvement. The dissection extent of the open group was significantly larger than that of the ETBC group (p = 0.006). In contrast, the ETBC group with less dissection extent showed a significantly higher incidence of transient hypoparathyroidism than the open group (59.2 vs. 29.6 %, p = 0.004). The average PTH decline of the ETBC group was significantly higher than that of the open group on postoperative day 1 (POD1) (32.1 vs. 21.6 pg/ml, p = 0.010). Furthermore, the ETBC group had a significantly higher portion of patients with a PTH hypoparathyroidism. Autotransplantation and inadvertent removal rates of parathyroid did not differ between the two groups. Although generally considered a safe method for patients with thyroid carcinoma, ETBC may increase the risk of transient hypoparathyroidism compared with conventional open surgery.

    Giant hiatal hernia (GHH) comprises 5% of hiatal hernia and is associated with significant complications. The traditional operative procedure, no matter transthoracic or transabdomen repair of giant hiatal hernia, is characteristic of more invasion and more complications. Although laparoscopic repair as a minimally invasive surgery is accepted, a part of patients can not tolerate pneumoperitoneum because of combination with cardiopulmonary diseases or severe posterior mediastinal and neck emphesema during operation. The aim of this article was to analyze our experience in gasless laparoscopic repair with abdominal wall lifting to treat the giant hiatal hernia. We performed a retrospective review of patients undergoing gasless laparoscopic repair of GHH with abdominal wall lifting from 2012 to 2015 at our institution. The GHH was defined as greater than one-third of the stomach in the chest. Gasless laparoscopic repair of GHH with abdominal wall lifting was attempted in 27 patients. Mean age was 67 years. The results showed that there were no conversions to open surgery and no intraoperative deaths. The mean duration of operation was 100 min (range: 90-130 min). One-side pleura was injured in 4 cases (14.8%). The mean postoperative length of stay was 4 days (range: 3-7 days). Median follow- up was 26 months (range: 6-38 months). Transient dysphagia for solid food occurred in three patients (11.1%), and this symptom disappeared within three months. There was one patient with recurrent hiatal hernia who was reoperated on. Two patients still complained of heartburn three months after surgery. Neither reoperation nor endoscopic treatment due to signs of postoperative esophageal stenosis was required in any patient. Totally, satisfactory outcome was reported in 88.9% patients. It was concluded that the gasless laparoscopic approach with abdominal wall lifting to the repair of GHH is feasible, safe, and effective for the patients who cannot tolerate the pneumoperitoneum.

    Full Text Available Total thyroidectomy is a surgery that removes all the thyroid tissue from the patient. The suspect of cancer in a thyroid nodule is the most frequent indication and it is presume when previous fine needle puncture is positive or a goiter has significant volume increase or symptomes. Less frequent indications are hyperthyroidism when it is refractory to treatment with Iodine 131 or it is contraindicated, and in cases of symptomatic thyroiditis. The thyroid gland has an important anatomic relation whith the inferior laryngeal nerve and the parathyroid glands, for this reason it is imperative to perform extremely meticulous dissection to recognize each one of these elements and ensure their preservation. It is also essential to maintain strict hemostasis, in order to avoid any postoperative bleeding that could lead to a suffocating neck hematoma, feared complication that represents a surgical emergency and endangers the patient’s life.It is essential to run a formal technique, without skipping steps, and maintain prudence and patience that should rule any surgical act.

    Full Text Available Objective: To change the gasless fetoscopy technique in order to reduce the diameter of entry orifices in the myometrium. Methods: Seven pregnant ewes were submitted to fetoscopy for repairing a large skin defect measuring 4.0 x 3.0 cm, created in the fetal lumbar region at the gestational age of 100 days. The defect was repaired through continuous suture of the skin with approximation of borders. Gasless fetoscopy was used for performing the suture with three orifices to allow entry of the trocar into the myometrium. A 5.0-mm optical trocar, and 3.5-mm grasping, dissecting and suturing forceps were used. After surgery, pregnancy was maintained until the animals were euthanized on the 133rd day of gestation, and the fetuses were evaluated. Results: Seven pregnant ewes underwent surgery; the first two cases were characterized as the Pilot Group, in which the endoscopic technique was modified and caliber reduction was possible in two out of three entry orifices in the myometrium. In the five remaining cases (Study Group, the repair was successfully carried out in all the fetuses, and the mean duration of fetoscopy was 98 minutes. There was a case of maternal death attributed to intrauterine infection. Mean intrauterine permanence after surgery was 12 days. Conclusions: The technique was successfully modified, allowing reduction of the uterine orifices necessary to perform the repair of a skin defect in the fetal lumbar region through a new fetoscopy technique. The impact of this modification in repair of myelomeningocele in human fetuses should be studied.

    2015-01-01

    BACKGROUND: Minimally invasive video-assisted thyroidectomy (MIVAT) is a technically demanding procedure and requires a surgical team skilled in both endocrine and endoscopic surgery. The aim of this report is to point out some aspects of the learning curve of the video-assisted thyroid surgery, through the analysis of our preliminary series of procedures. PATIENTS AND METHODS: Over a period of 8 months, we selected 36 patients for minimally invasive video-assisted surgery of the thyroid. The patients were considered eligible if they presented with a nodule not exceeding 35 mm and total thyroid volume time, post-operative complications, hospital stay and cosmetic outcomes of the series. RESULTS: We performed 36 total thyroidectomy and in one case we performed a consensual parathyroidectomy. The procedure was successfully carried out in 33 out of 36 cases (conversion rate 8.3%). The mean operating time was 109 min (range: 80-241 min) and reached a plateau after 29 MIVAT. Post-operative complications included three transient recurrent nerve palsies and two transient hypocalcemias; no definitive hypoparathyroidism was registered. The cosmetic result was considered excellent by most patients. CONCLUSIONS: Advances in skills and technology allow surgeons to easily reproduce the standard open total thyroidectomy with video-assistance. Although the learning curve represents a time-consuming step, training remains a crucial point in gaining a reasonable confidence with video-assisted surgical technique. PMID:25883451

    Full Text Available Aim: Completion thyroidectomy is required at situations such as recurrent nodular goiter and malignant findings at histopathology after primary operation for noduler goiter. The aim of this study was to investigate the indications for the completion thyroidectomy and the effect of the operation timing on morbidity.Materials and Methods: Thirty-one consecutive patients (26 females and 5 males with a mean age of 36.5±7.7 years (range, 23-55 yrs that underwent completion thyroidectomy were investigated. The patients, who needed re-operation for recurrence with diagnosis of histopathologically proven malignancy or re-operated for recurrence, were included. Results: Seventeen patients had the second operation performed within 10 days or more than 90 days after initial operation (group 1. Fourteen patients had re-operation between 10 and 90 days after the first procedure (group 2. Histopathological examination after the completion thyroidectomy revealed remnant tumour in 7 patients (23%, two of them in the contralateral lobe. One patient suffered from a permanent hypoparathyroidism in group 1 and a permanent vocal cord paralysis in group 2.Conclusion: Our results suggest that other treatment modalities except total thyroidectomy are insufficient, since remnant tumour was seen over 20% of the histopathological specimens of the completion thyroidectomy. Timing of completion thyroidectomy had no effect on the thyroid cancer development. Total thyroidectomy can be preferred in the surgical management of tiroid cancers or benign nodular goiter.

    To evaluate the incidence and predictive factors for transient and permanent hypocalcemia and hypoparathyroidism following thyroidectomy. We studied all the 162 patients that underwent thyroid surgery in the ENT department of the Centro Hospitalar Vila Nova Gaia/Espinho from January 2005 to December 2014. We reviewed pre-operative, 6h and 12h after surgery ionized calcium and PTH levels. All patients were reviewed and evaluated according to the following criteria: gender, age, thyroid function, histologic diagnosis of the specimen, surgery extension and presence or absence of hypoparathyroidism. There were 31 (19.1%) cases of transient hypoparathyroidism and 8 (5%) of permanent hypoparathyroidism. No significant difference was found for transient hypoparathyroidism when patients were analyzed by gender. However, all cases of permanent hypoparathyroidism were observed in female individuals. Comparing hemithyroidectomy with all other surgical procedures, we found that extension of surgery was a great predictor of transient (p=0.0001) and permanent (p=0.001) hypoparathyroidism. Diagnosis of malignancy was a strong predictor of transient hypoparathyroidism (p=0.002). It was also associated with permanent hypoparathyroidism, although differences did not reach statistical significance (p=0.096). Extension of surgery (total thyroidectomy) and diagnosis of malignancy are predictors of transient and permanent hypoparathyroidism.

    To establish if the indication for different approaches for thyroidectomy and the incision length provided by means of pre-operative assessment of gland volume and size of nodules resulted in safe and effective outcomes and in any notable aesthetic or quality-of-life impact on patients. Ninehundred eightytwo consecutive patients, undergoing total thyroidectomy, were enrolled. The thyroid volume and maximal nodule diameter were measured by means of ultrasounds. Based on ultrasounds findings, patients were divided into three groups: minimally invasive video assisted thyroidectomy (MIVAT), minimally invasive thyroidectomy (MIT) and conventional thyroidectomy (CT) groups. The data concerning the following parameters were collected: operative time, postoperative complications, postoperative pain and cosmetic results. The MIVAT group included 179 patients, MIT group included 592 patients and CT group included 211 patients. Incidence of complications did not differ significantly in each group. In MIVAT and MIT group, the perception of postoperative pain was less intense than CT group. The patients in the MIVAT (7±1.5) and MIT (8±2) groups were more satisfied with the cosmetic results than those in CT group (5±1.3) (p= MIT is a technique totally reproducible, and easily convertible to perform surgical procedures in respect of the patient, without additional complications, increased costs, and with better aesthetic results.

    Uterine leiomyoma causes considerable morbidity in women. This study systematically reviewed the efficacy and safety of gasless laparoscopic myomectomy (GLM) in the management of uterine leiomyoma by comparing GLM with other minimally invasive procedures. Cochrane Library, Pub- Med, EMBASE, Web of Science, WANFANG database and China National Knowledge Infrastructure (CNKI) were searched for studies published in English or Chinese between January 1995 and May 2015, and related references were traced. Study outcomes from randomized controlled trials and retrospective cohort studies were presented as mean difference (MD) or odds ratio (OR) with a 95% confidence interval (CI). Seventeen studies (including 1862 patients) meeting the inclusion criteria, including 934 treated with GLM and 928 treated with other minimally invasive procedures were reviewed. The results of meta-analysis revealed that GLM resulted in significantly shorter operating time [MD=-10.34, 95% CI (-18.12,-2.56), Ppost-operative fever [MD=-0.52, 95% CI (-1.46, 0.42)] between the two groups. Additionally, GLM was associated with lower febrile morbidity, lower postoperative abdominal pain, and higher postoperative hemoglobin than other minimally invasive procedures for the treatment of uterine leiomyoma. In conclusion, GLM and other minimally invasive procedures are feasible, safe, and reliable for uterine leiomyoma treatment. However, available studies show that GLM is more effective and safer than other minimally invasive approaches.

    Permanent hypoparathyroidism is the most common long-term complication after total thyroidectomy and it can cause significant morbidity and increased costs. Its incidence varies from 30% to 60%. The surgical technique and the extent of thyroidectomy are related to parathyroid injury and hypoparathyroidism. The glands should be identified in situ, carefully manipulated and preserved, as well as their vascularization. In case of incidental removal, routine autotransplantation is advocated. Low calcium levels, identification of fewer than two parathyroid glands at surgery, reoperation for bleeding, Graves disease and heavier thyroid specimens were considered independent predictors of permanent hypocalcemia. Intraoperative parathyroid hormone (PTH) measurements allows the early detection of hypocalcemia. Treatment is recommended for patients with symptoms of hypocalcemia or corrected serum calcium Hypoparathyroidism is the most common long-term complication after total thyroidectomy. Adequate recognition and management decrease its morbidity and costs.

    Optimal thyroxine replacement following total thyroidectomy is critical to avoid symptoms of hypothyroidism. The aim of this study was to determine the best formula to determine the initiated replacement dose of levothyroxine immediately following total thyroidectomy. Prospective study. All patients were initiated on 100 μg levothyroxine and titrated to within the reference range for TSH and free T4. Correlations to height, weight, age, lean body mass (LBM), body surface area (BSA) and body mass index (BMI) were calculated. One hundred consecutive adult patients underwent total thyroidectomy for non-malignant disease. Comparison between three methods of levothyroxine dose prediction, aiming for a levothyroxine dose correct to within 25 μg of actual dose required. Correlations were seen between levothyroxine dose and patient age (r=-0.346, Pregression equation was calculated (predicted levothyroxine dose=[0·943 × bodyweight] + [-1.165 × age] + 125.8), simplified to (levothyroxine dose= bodyweight - age + 125) pragmatically. Initiating patients empirically on 100 μg post-operatively showed that 40% of patients achieved target within 25 μg of their required dose; this increased to 59% when using a weight-only dose calculation (1.6 μg/kg) and to 72% using the simplified regression equation. A simple calculated regression equation gives a more accurate prediction of initiated levothyroxine dose following total thyroidectomy, reducing the need for outpatient attendance for dose titration. © 2011 Blackwell Publishing Ltd.

    Permanent hypoparathyroidism after total thyroidectomy is a rare but potentially serious iatrogenic complication. The aim of this study was to investigate the rate of recovery from postoperative, permanent hypoparathyroidism in patients undergoing thyroidectomy without parathyroid autotransplantation. This study was a prospective case series with a postoperative follow-up of up to 3 years. We enrolled patients with thyroid cancer who underwent total thyroidectomy with central compartment dissection, with or without lateral neck dissection, and who had postoperative permanent hypoparathyroidism, defined as serum levels of intact parathyroid hormone (PTH) hypoparathyroidism was defined as return to normal serum levels of PTH (15-65 pg/mL) and calcium (8.5-10.1 mg/dL) without calcium and/or vitamin D supplementation. In the 1467 patients who underwent total thyroidectomy, 22 presented with permanent postoperative hypoparathyroidism. In 5 of these 22 patients, the PTH levels increased steadily and returned to normal in 27.6±2.9 months, after which supplementation of calcium and vitamin D could be discontinued. Although recovery from permanent hypoparathyroidism is rare, patients should be monitored for serum PTH levels so that unnecessary treatments such as calcium and vitamin D supplementation can be avoided.

    Objective: To assess the efficacy and safety of total thyroidectomy for benign multi-nodular goiter. Study design: Descriptive study Place and Duration of Study: The study was conducted in the Department of General Surgery, Combined Military Hospital Kharian from January 2004 to December 2008. Materials and Methods: A total of 66 patients with bilateral benign multi-nodular goiter (61 females and 5 males) underwent total thyroidectomy. Sixty two cases were euthyroid while 4 had hyperthyroidism. Surgical dissection techniques involved identifying both recurrent laryngeal nerves through out their course, securing of parathyroid glands with their intact blood supply and ligation of inferior thyroid artery branches close to the thyroid capsule. All the patients were evaluated post operatively for signs of recurrent laryngeal nerve injury and hypoparathyroidism and other complications. All patients were put on thyroxin replacement therapy post-operatively and were followed for 9 to 12 months. There was no injury to the recurrent laryngeal nerves. One case of injury to external laryngeal nerve was found. Transient hypocalcaemia occurred in 4 patients without permanent hypoparathyroidism. All cases of transient hypocalcaemia recovered fully within 3 months. Four patients had occult malignancy diagnosed post-operatively on histo-pathology. In experienced hands, total thyroidectomy is an effective and relatively safe operation for benign multi-nodular goitre and its complication rate is same as that of a sub-total thyroidectomy.

    Parathyroid hormone (PTH) levels are often measured after thyroid surgery and are used to detect patients at risk for postoperative hypoparathyroidism. However, there is a lack of consensus in the literature about how to define the recovery of parathyroid gland function and when to classify hypoparathyroidism as permanent. The goals of this study were to determine the incidence of low postoperative PTH in total thyroidectomy patients and to monitor their time course to recovery of parathyroid gland function. We identified 1054 consecutive patients who underwent a total or completion thyroidectomy from January, 2006-December, 2013. Low PTH was defined as a PTH measurement hypoparathyroid if they had not recovered within 1 y. Recovery of parathyroid gland function was defined as PTH ≥10 pg/mL and no need for therapeutic calcium or activated vitamin D (calcitriol) supplementation to prevent hypocalcemic symptoms. Of 1054 total thyroidectomy patients, 189 (18%) had a postoperative PTH hypoparathyroidism. Surprisingly, 50% of those patients had recovery of PTH levels yet still required supplementation to avoid symptoms. Most patients with a low postoperative PTH recover function quickly, but it can take up to 1 y for full resolution. Hypoparathyroidism needs to be defined not only by PTH levels but also by medication requirements. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Introduction: Voice disorders are a well-known complication which is often associated with thyroid gland diseases and because voice is still the basic mean of communication it is very important to maintain its quality healthy. Objectives: The aim of this study referred to questions whether there is a statistically significant difference between results of voice self-assessment, perceptual voice assessment and acoustic voice analysis before and after thyroidectomy and whether there are statistically significant correlations between variables of voice self-assessment, perceptual assessment and acoustic analysis before and after thyroidectomy. Methods: This scientific research included 12 participants aged between 41 and 76. Voice self-assessment was conducted with the help of Croatian version of Voice Handicap Index (VHI. Recorded reading samples were used for perceptual assessment and later evaluated by two clinical speech and language therapists. Recorded samples of phonation were used for acoustic analysis which was conducted with the help of acoustic program Praat. All of the data was processed through descriptive statistics and nonparametric statistical methods. Results: Results showed that there are statistically significant differences between results of voice self-assessments and results of acoustic analysis before and after thyroidectomy. Statistically significant correlations were found between variables of perceptual assessment and acoustic analysis. Conclusion: Obtained results indicate the importance of multidimensional, preoperative and postoperative assessment. This kind of assessment allows the clinician to describe all of the voice features and provides appropriate recommendation for further rehabilitation to the patient in order to optimize voice outcomes.

    Both Total and Subtotal Thyroidectomy are correct treatment options for symptomatic Euthyroid Multinodular Goitre. The choice depends upon surgeon's preference due to consideration of disadvantages like permanent hypothyroidism in Total Thyroidectomy and high chances of recurrence in Subtotal Thyroidectomy. Many surgeons believe that there is a higher incidence of Recurrent Laryngeal nerve injury in Total Thyroidectomy which affects their choice of surgery. This study aimed to compare the incidence of recurrent laryngeal nerve injury in total versus subtotal thyroidectomy. This non randomized controlled trial was carried out at Department of Surgery and ENT of Ayub Teaching Hospital Abbottabad, and Combined Military Hospital Rawalpindi from 1st September 2013 to 30th August 2014. During the period of study, patients presenting in surgical outpatient department with euthyroid multinodular goitre having pressure symptoms requiring thyroidectomy were divided into two groups by convenience sampling with 87 patients in group 1 and 90 patients in group 2. Group-1 was subjected to total thyroidectomy and Group -2 underwent subtotal thyroidectomy. All the patients had preoperative Indirect Laryngoscopy examination and it was repeated postoperatively to check for injury to the recurrent laryngeal nerve. A total of 177 patients were included in the study. Out of these, 87 patients underwent total thyroidectomy (Group-1). Two of these patients developed recurrent laryngeal nerve injury (2.3%). In group-2 subjected to subtotal thyroidectomy, three of the patients developed recurrent laryngeal nerve injury (3.3%). The p-value was 0.678. The overall risk of injury to this nerve in both surgeries combined was 2.8%. There is no significant difference in the risk of recurrent laryngeal nerve damage in patients undergoing total versus subtotal thyroidectomy.

    We retrospectively evaluated a series of patients who underwent minimally invasive video-assisted thyroidectomy (MIVAT) to define its advantages or disadvantages. Between May 2005 and March 2008, 68 patients underwent MIVAT. Sixty-nine patients who underwent conventional thyroidectomy (CT) during the period before the introduction of the MIVAT technique in our department-chosen with the same inclusion criteria used for MIVAT-served as matched controls. The eligibility criteria for both groups was thyroid nodules surgery. Forty-five MIVAT and 43 CT patients underwent hemithyroidectomy. Twenty-three MIVAT and 26 CT patients underwent total thyroidectomy. No differences were found in terms of complications, operative time, and radicality of the procedure. Patients who underwent MIVAT experienced significantly less pain, better cosmetic results, and shorter hospital stay than patients who underwent conventional surgery The MIVAT technique, in selected patients, seems to be a valid option for thyroidectomy and even preferable to conventional surgery because of its significant advantages, especially in terms of cosmetic results, postoperative pain, and postoperative recovery.

    Patients with goiter often complain of compressive symptoms, which may contribute to symptoms of obstructive sleep apnea (OSA). However, the impact of thyroid enlargement on these symptoms is not clear. Therefore, we sought to evaluate whether symptoms of sleep apnea resolved after thyroidectomy by using a validated questionnaire. The Berlin Questionnaire, a validated sleep apnea assessment tool, was provided to patients at a single academic institution before and after thyroidectomy. Patients who admitted to symptoms of snoring were asked to complete the questionnaire before and 8 weeks after surgery to assess for improvement in symptoms. The questionnaire uses 3 categories of questions to determine risk of sleep apnea. Two symptom categories must be positive for a patient to be considered high risk for sleep apnea. Forty-five patients completed both pre- and postoperative questionnaires. The average age of patients completing the questionnaire was 53±2 years, and 78% of patients were female. Average body mass index was 33.3±1.4 kg/m(2). Based on their preoperative questionnaire score, 71% of patients were considered to be high risk for OSA, and this decreased to 51% after surgery (p=0.002). Overall scores significantly improved after surgery (mean 2.0 vs. 1.6, psymptoms, gland weight at resection, presence of thyroiditis, or the largest dimension of the gland at resection. Thyroid surgery appears to significantly improve symptoms of OSA in patients who screened positive for symptoms before surgery. Evaluation of patients with OSA should include evaluation of thyroid disease, as symptoms of sleep apnea may improve with thyroidectomy.

    Consensus regarding the difference of postoperative hypoparathyroidism following completion thyroidectomy (CT) and total thyroidectomy (TT) has yet to be reached. We compare the occurrence of postoperative hypoparathyroidism between CT and TT for differentiated thyroid cancer (DTC), and explore the predictive factors for postoperative hypoparathyroidism. We retrospectively reviewed 221 consecutive patients underwent CT or TT for DTC between February 2012 and March 2014. Patients' demographic and clinical data of the two groups were analyzed. There were 57 CTs and 164 TTs. Temporary hypoparathyroidism occurred in 12.3% (7 of 57) and 28.0% (46 of 164) of patients in the CT and TT groups, respectively. In univariate analysis, type of surgical procedure (CT or TT) and extent of central lymph node dissection (CND) (unilateral or bilateral) were significantly associated with the postoperative temporary hypoparathyroidism (P hypoparathyroidism. Although temporary hypoparathyroidism was lower in the CT group, our analysis indicates the difference is due to the extent of CND rather than type of surgical procedure (CT vs. TT). Only bilateral CND is an independent risk factor for temporary hypoparathyroidism after thyroidectomy. J. Surg. Oncol. 2016;113:522-525. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

  9. A Case of Hypercalcemia after Thyroidectomy

    Full Text Available Total thyroidectomy is complicated by hypoparathyroidism in 1-3% of patients. Hypoparathyroidism is treated with oral calcium and vitamin-D supplements. Everyday use of calcium and vitamin D can lead sometimes to hypercalcemia. Ingestion of large amounts of calcium and absorbable alkali that cause hypercalcemia, various degrees of renal failure, and metabolic alkalosis, can be associated with a diagnosis of calcium-alkali syndrome. This syndrome was first identified as milkalkali syndrome, after treatment of peptic ulcer disease with milk and alkali which was widely adopted at the beginning of the 20th century. With the introduction of histamine-2 blockers and proton pump inhibitors, the occurrence of milk-alkali syndrome became rare; however, it has emerged recently as calcium-alkali syndrome because of the wide availability and increasing use of calcium carbonate, mostly for osteoporosis prevention. We present a female patient with hypoparathyroidism who presented with hypercalcemia and alkalosis as a result of treatment with calcium carbonate, vitamin D and thiazide diuretic. The patient was treated successfully by discontinuation of the above drugs, intravenous fluid administration and enhancement of calcium renal excretion. Hypercalcemia presenting as calcium-alkali syndrome is a diagnosis that requires a high index of suspicion in order to quickly identify the disorder and initiate appropriate therapy. It is important for clinicians to keep the syndrome on their list of differential diagnosis.

    Thyroid surgery is the most commonly performed procedure in the field of endocrine surgery. Studies are still ongoing on the development of a single algorithm for diagnosis and care of patients at risk of postoperative hypoparathyroidism. The aim of the study was to determine the biochemical marker that would allow the most accurate diagnosis of patient groups at risk of developing hypoparathyroidism and to identify risk factors for this disorder. The prospective study included 142 consecutive patients undergoing total thyroidectomy for benign goiter from January 1st 2014 to December 31st 2015. Serum intact parathyroid hormone (iPTH), total calcium (Ca), phosphate (P), and magnesium (Mg) levels have been measured preoperatively and at 1, 6, 24, and 48 h postoperatively. Clinical symptoms of hypoparathyroidism developed in 25 (17.6%) of 142 patients. The best diagnostic accuracy for hypoparathyroidism based on ROC curves was obtained for iPTH at 6h (AUC 0.942; 95% CI: 0.866-1.000, phypoparathyroidism, by 68% (p=0.012) and 61% (p=0.007), respectively. A 1% decline in iPTH from baseline increased the risk of hypoparathyroidism by 15% (phypoparathyroidism are the decline in ΔiPTH at 6h by > 65% or iPTH level at 6h hypoparathyroidism. Preoperative higher concentrations of Ca and iPTH are protective factors for the development of this disorder.

    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.

    Multinodular goitre is one of the commonest thyroid diseases encountered in the practice of surgery. The most common surgery being performed for multinodular goitre is subtotal thyroidectomy. Total thyroidectomy is designed to remove all of the thyroid tissue. The objective of this study was to evaluate total thyroidectomy as a primary elective procedure for treatment of multinodular thyroid disease. This descriptive study was carried out at Combined Military Hospital Rawalpindi from June 2003 to September 2006. 88 patients of multinodular thyroid disease were included. Patients having evidence of recurrent laryngeal nerve damage, recurrent goitre, evidence of altered parathyroid functions or evidence of malignancy were excluded. All patients underwent total thyroidectomy by the same team of surgeons and the patients were closely followed up for postoperative complications especially in terms of recurrent laryngeal nerve damage and hypocalcaemic tetany. No major postoperative complication was noted. Only 1 patient (1.14%) developed unilateral recurrent laryngeal nerve damage and 2 patients (2.27%) developed transient hypocalcaemia that recovered quickly. Total thyroidectomy as a primary elective procedure in multinodular thyroid disease is a safe option and it removes the disease process completely, lowers local recurrence rates and avoids the substantial risks of re operative surgery.

    Background Thyroid disorders are very common in adults. Despite advances in conservative management, surgery remains a treatment modality of choice in many cases. The mortality and morbidity of thyroidectomy are low, but long-term postoperative hypoparathyroidism (HPT) remains a prominent complication of the procedure. The aim of this study was to assess the incidence of permanent HPT and identify the risk factors for this complication in a cohort of post-thyroidectomy patients followed at a District Endocrine Clinic. Material/Methods This was a retrospective analysis of 401 patients followed up at a Regional/District Endocrine Clinic, who had undergone thyroid surgery in the years 1993–2011. The percentage of patients with permanent (>12 months) HPT was the primary endpoint of the study. The statistically analyzed data of patients with permanent HPT versus the remaining patients free from postoperative complications included their demographic data, indications for surgical treatment of their thyroid disorder, and extent of the thyroid resection. The risk factors for postoperative hypoparathyroidism were assessed using logistic regression analysis. Results Permanent HPT following surgery on the thyroid gland occurred in 8.5% of the patients. It was more frequent following total thyroidectomy (20.2%) than near-total thyroidectomy (6.7%) or subtotal thyroidectomy (4.2%); phypoparathyroidism when compared to less extensive thyroid resection modes in patients with benign thyroid diseases.

    The extent of thyroidectomy in Graves' disease is still controversial. We compared the outcome of two groups of patients with Graves' disease who underwent total and subtotal thyroidectomy, respectively. One hundred forty patients were treated by subtotal (ST, n = 80) or total thyroidectomy (TT, n = 60) between 1988 and 1994 for a large goiter or recurrence of hyperthyroidism after antithyroid drugs. Surgical complications, relapse of hyperthyroidism, and serum levels of antibodies were evaluated. Thyroid-stimulating hormone receptor and thyroperoxidase antibodies significantly decreased in 44 of 60 and in 27 of 60, respectively, of TT patients and in 65 of 80 and 8 of 80, respectively, of ST patients. Thyroid-stimulating hormone antibody levels increased in three ST patients who had relapse of hyperthyroidism and in no TT patients; thyroperoxidase antibodies increased in nine ST patients (four with relapse of hyperthyroidism) and in no TT patients. Vocal cord palsy occurred in two ST (2.5%) and in 1 TT (1.7%) patients; hypoparathyroidism occurred in three ST (3.8%) and in two (3.3%) TT patients. Total thyroidectomy does not present more complications with respect to subtotal thyroidectomy, but it avoids the worsening of thyroid humoral autoimmunity and the relapse of hyperthyroidism. Thus it could represent the treatment of choice in Graves' disease.

    Hypoparathyroidism is a common complication with thyroid surgery. The ability to predict a high risk of permanent hypoparathyroidism is important for individual prognosis and follow-up. Permanent hypoparathyroidism, defined as continuing need for vitamin D medication at 1-year post-operatively, was investigated in patients after total thyroidectomy. Blood levels of calcium and parathyroid hormone (PTH) were measured intra-operatively, the day after surgery and at 1 month post-operatively. Logistic regression analysis was performed to investigate the risk of vitamin D treatment at last follow-up, calculated as odds ratios (ORs) with 95 % confidence intervals (CIs). Patients were followed until cessation of vitamin D and/or calcium medication, until death, loss to follow-up, or end of follow-up, whichever came first. A total of 519 patients were included. The median (range) follow-up in patients unable to cease vitamin D was 2.7 (1.2-10.3) years. The rate of permanent hypoparathyroidism was 10/519, 1.9 %. Parathyroid auto-transplantation was performed in 90/519 (17.3 %) patients. None of these developed permanent hypoparathyroidism, nor did any patient with normal PTH day 1 (>1.6 pmol/l or 15 pg/ml). The adjusted risk (OR, 95 % CI) for permanent hypoparathyroidism for log PTH on day 1 was 0.25 (0.13-0.50). In patients not auto-transplanted and with unmeasurable PTH day 1 (hypoparathyroidism. Auto-transplantation protects against permanent hypoparathyroidism, whereas low PTH day 1 is associated with high risk.

    This review evaluates those main risk factors that can affect patients undergoing thyroidectomy, to reach a better pre- and post-operative management of transient and permanent hypoparathyroidism. The transient hypoparathyroidism is a potentially severe complication of thyroidectomy, including a wide range of signs and symptoms that persists for a few weeks. The definitive hypoparathyroidism occurs when a medical treatment is necessary over 12 months. Risk factors that may influence the onset of this condition after thyroidectomy include: pre- and post-operative biochemical factors, such as serum calcium levels, vitamin D blood concentrations and intact PTH. Other involved factors could be summarized as follow: female sex, Graves' or thyroid neoplastic diseases, surgeon's dexterity and surgical technique. The medical treatment includes the administration of calcium, vitamin D and magnesium sometimes. Although biological and biochemical factors could be related to iatrogenic hypoparathyroidism, the surgeon's experience and the used surgical technique still maintain a crucial role in the aetiology of this important complication.

    Full Text Available Papillary carcinoma is a prominent malignancy originating from follicular cells. This disease generally shows an indolent character, but patients demonstrating certain clinicopathological features have a dire prognosis. At present, Western countries adopted almost routine total thyroidectomy with radioactive iodine (RAI ablation, while limited thyroidectomy with extensive prophylactic lymph node dissection has traditionally been performed for most patients in Japan. Recently, accurate evaluation of carcinoma stage can be performed on preoperative imaging studies, especially on ultrasonography. It is therefore important to treat papillary carcinoma patients depending on clinicopathological features rather than in a stereotyped fashion. In this paper, appropriate extension of thyroidectomy and lymph node dissection is discussed based on Western and recently published Japanese guidelines and the experience in Kuma Hospital.

    Full Text Available Background: In 1990, Ramirez introduced a new procedure to close abdominal wall hernia (AWH, called "components separation technique (CST". Thanks to endoscopy, surgical repair possibilities have risen, reducing the operative trauma and preserving vascular and neuronal anatomical structures. This report aims to describe a single port endoscopic approach for CST to repair the abdominal wall of a patient undergoing surgery for abdominal aneurysm and already subject to placement of a mesh for AWH. Methods: We performed endoscopic-assisted CST, using a single-port access with a gasless technique. Conclusion: CST is a useful procedure to close large abdominal wall incisional hernia avoiding the use of mesh, notably under contamination, when prosthetic material use is contraindicated. The endoscopic-assisted CST produces same results than the conventional open separation technique and also minimised tissue trauma that ensures blood supply and prevents postoperative wounds complications. The described single port method was found to be safe and effective to close large midline abdominal hernias when a primary open or laparoscopic closure is not feasible or when patients have been previously treated with abdominal meshes.

    Background Many studies have reported that drainage after thyroidectomy does not decrease the rate of local postoperative complications. We sought to review the safety of thyroidectomy combined with cervical neck dissection (CND) without drainage. Methods The medical records of consecutive patients who underwent thyroidectomy without drainage were retrospectively reviewed. Two groups were defined depending on whether CND was or was not performed. The main outcome was identification of patients with cervical bleeding, hematoma or seroma. Results We included 1127 patients (139 who had CND and 988 who did not). Of these, 207 patients (18%) had transient postoperative hypocalcemia, 9 (0.8%) had permanent postoperative hypoparathyroidism, 56 (5%) had transient postoperative hoarseness and 7 (0.6%) had permanent vocal cord paralysis. A total of 44 patients (4%) experienced postoperative hematoma and/or seroma: 8 patients (6%) who had CND and 36 (4%) who did not. There was no major bleeding in the 2 groups; all patients had minor bleeding or seroma not requiring surgical intervention. The postoperative stay in hospital for both groups was 1 day in 92% of patients. Wound infection occurred in 0.8% of all patients: 1 (0.7%) who had CND and 8 (0.8%) who did not. There was no significant difference between the groups in overall perioperative complications or in time of hospital discharge. Conclusion Thyroidectomy without drains is safe and effective, even in combination with CND. PMID:22449723

    Full Text Available We aimed to test the hypothesis that Minimally Invasive Video-assisted Thyroidectomy (MIVAT affords comparable safety and efficacy as to the open conventional surgery, when dealing with patients with unilateral thyroid nodules or follicular lesions, in terms of cosmetic results, intraoperative and postoperative complications, postoperative pain and hospital stay. Materials And Methods: This was a single-blinded randomised controlled trial comparing the MIVAT with conventional thyroidectomy. The primary endpoints of the study were measurement of postoperative pain after 24 and 48 hours from operation and self-rated patient satisfaction with cosmetic outcome three months postoperatively. The secondary outcome measures were operative time, incidence of temporary and permanent recurrent laryngeal nerve injury, postoperative haematoma formation, length of incision, and duration of hospital stay. Results: Operative time was significantly less with open thyroidectomy than with MIVAT, while MIVAT was associated with less pain 24 hours postoperatively. Blood loss did not reach significance between procedures. Comparisons between the two procedures with regard to pain scores after 24 and 48 hours, respectively, depicted statistically significant differences in favour of the MIVAT after 24 hours. MIVAT was associated with less scarring and more satisfactory cosmetic results. There were statistically no significant differences between both procedures for the presence of transient recurrent laryngeal nerve palsy and hypoparathyroidism. Conclusions: MIVAT is a safe procedure that produces outcomes, in view of short-term adverse events, similar to those of open thyroidectomy, and is superior in terms of immediate postoperative pain and cosmetic results.

    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 Introduction Completion thyroidectomy is defined as the surgical removal of the remnant thyroid tissue following procedures of less than total or near-total thyroidectomy. Whether thyroid reoperations are associated with an increased complication risk is controversial. Objective A retrospective analysis was done of patients undergoing completion thyroidectomy for cancer of the thyroid who had undergone surgery elsewhere for solitary thyroid nodule. The incidence of surgical complications in these patients after reoperation was investigated in this study. Material and methods The study included a total of 53 patients who had undergone thyroid lobectomy for a solitary nodule as initial surgery elsewhere and were referred to our institute for completion thyroidectomy when the histopathology revealed malignancy. Results There were 53 patients, 43 females and 10 males. Their mean age was 34.7±12.12 years (range 19–65 years. After initial surgery, the histopathology revealed papillary carcinoma in 46 patients (86.8%, follicular carcinoma in 7 (13.2%. Fourteen out of 53 patients had recurrent laryngeal nerve palsy after initial surgery (26.4%. None of the patients had clinical hypocalcemia after the first surgery. One or more parathyroid glands were identified and preserved in 52 patients (98.1% in the process of completion thyroidectomy. No patient had additional recurrent nerve injury at the second surgery. The mean serum calcium value preoperatively was 8.96±0.39 mg/dL, and six months after surgery serum calcium was 8.74±0.56 mg/dL. Mean follow-up was 18 months. Transient hypoparathyroidism occurred in 24.5% patients. Five patients were lost to follow-up. Permanent and symptomatic hyperparathyroidism occurred in eight patients (16.67%. Conclusions Completion thyroidectomy is a safe and appropriate option in the management of well-differentiated thyroid cancer. It removes disease on the ipsilateral and contralateral side of the thyroid and

    There is clinical evidence that post-total thyroidectomy (TT) patients can present persistent asthenia. The aim of this study was to evaluate the prevalence of asthenia symptoms in such patients, assess whether a chronic asthenia syndrome could be caused by TT or become evident after it. An observational study was carried out comparing two groups of 100 patients each, all with homogeneous characteristics. Group A was treated with total lobectomy (TL), Group B with TT. All patients presented normal thyroid hormone levels. The patients were interviewed in order to identify the ones affected by post-operative asthenia persisting for at least six months, with reduced ability to perform physical and mental work, not showing improvement with rest. The severity of the symptoms has been measured by means of the brief fatigue inventory (BFI). Statistical analysis was performed to evaluate statistically significative differences between groups and prognostic factors in TT group. The incidence of post-operative asthenia was 0 % after TL and 25 % after TT, with the operation being the only significant variable. Asthenia is well known as symptom of post-thyroidectomy, but it has not been adequately investigated as consequence of surgery. We demonstrated that the complete removal of the thyroid gland could determine chronic post-thyroidectomy asthenia, although with intensity limited to low/moderate. Post-thyroidectomy asthenia is a relevant sequela interfering with quality of life of at least 25 % of patients operated, suggesting the need to identify its real causes and limit the indication to TT only when strictly required.

    Objective: To determine the risk of postthyroidectomy hypocalcaemia by measuring parathyroid hormone (PTH) level after thyroidectomy. Study Design: Cross-sectional study. Place and Duration of Study: Baqiyatallah Hospital, Tehran, Iran, from March 2008 to July 2010. Methodology: All included patients were referred for total or near bilateral thyroidectomy. Serum Calcium (Ca) and PTH levels were measured before and 24 hours after surgery. In low Ca cases or development of hypocalcaemia symptoms, daily monitoring of Ca levels were continued. Data were analyzed using SPSS 20 software (SPSS, Chicago, IL, USA). A p-value less than 0.05 were considered statistically significant. To assess the standard value of useful predictive factors, we used receiver operating characteristic (ROC) curves. Results: Of total 99 patients who underwent bilateral thyroidectomy, 47 patients (47.5%) developed hypocalcaemia, out of them, 12 (25.5%) became symptomatic while 2 patients developed permanent hypoparathyroidism. After surgery, mean rank of PTH level within the normocalcaemic and hypocalcaemic patients was 55.34 and 44.1 respectively, p=0.052. Twenty four hours after surgery, 62% drop in PTH was associated with 83.3% of symptomatic hypocalcaemic. For diagnosis of symptomatic hypocalcaemia, 62% PTH drop had sensitivity and specificity were 83.3% and 90.80%. The area under the ROC curve for the PTH postoperative and PTH drop for diagnostic symptomatic hypocalcaemia were 0.835 and 0.873 respectively. Conclusion: Measuring PTH levels after 24 hours postthyroidectomy is not reliable factor for predicting hypocalcaemia itself. For predicting the risk of hypocalcaemia after thyroidectomy it is more reliable to measure the serum PTH level before and after operation and compare the reduction level of percentage of PTH drop for predicting the risk of hypocalcaemia.

    The aim of this study was to evaluate the risk factors for hypoparathyroidism after total thyroidectomy and to determine whether early postoperative serum levels of calcium and phosphorus could be used to predict its development. The study group consisted of 1030 patients who had undergone total thyroidectomy at our institution between March 2008 and July 2014. The clinicopathologic characteristics, indications for the operation, and surgical details of normocalcemic and hypocalcemic patients were compared, and variations in serum calcium and phosphorus levels were measured every day after the operation. Of the 1030 patients, 291 (28.2%) were found to have transient hypocalcemia and 27 (2.6%) had permanent hypocalcemia. On univariate analysis, younger age (P = 0.001), female gender (P hypoparathyroidism, with 92% specificity. Female gender (P = 0.001), extent of CND (P = 0.014), and PTG in permanent pathologic sections (P = 0.035) were found to be significant factors affecting the development of hypocalcemia. Despite some study limitations, we suggest that the relative changes in the serum levels of calcium (20%) and of phosphorus (40%) on the second postoperative day may be reliable predictors of post-thyroidectomy hypoparathyroidism.

    Abstract The main objective of this study is to investigate the outcome between surgical procedures and the risk of development of hypoparathyroidism followed by surgical procedure in patients with thyroid disorders. We analyzed the data acquired from Taiwan's Bureau of National Health Insurance (BNHI) research database from 1998 to 2011 and found 9316 patients with thyroid surgery. Cox regression model was used to calculate the hazard ratio (HR). A count of 314 cases (3.4%) of hypoparathyroidism was identified. The 9 years cumulated incidence of hypoparathyroidism was the highest in patient undergone bilateral total thyroidectomy (13.5%) and the lowest in the patient with unilateral subtotal thyroidectomy (1.2%). However, in the patients who had undergone unilateral subtotal, the risk was the highest in bilateral total (HR: 11.86), followed by radical thyroidectomy with unilateral neck lymph node dissection (HR: 8.56), unilateral total (HR, 4.39), and one side total and another side subtotal (HR: 2.80). The extent of thyroid resection determined the risk of development of hypoparathyroidism. It is suggested that the association of these factors is investigated in future studies. PMID:29068988

    Communication failures may result in inadequate treatment and patient harm, and are among the most common causes of sentinel events. Checklists are part of cycles to improve quality of the care process, promote communication between professionals involved in the different stages, help detect failures and risks, and increase patient safety. The lack of checklists at each stage was identified as a factor contributing to communication failures. To design checklists at different stages of the thyroidectomy care process to improve the communication between the professionals involved. Multidisciplinary working team consisting of specialists in otolaryngology, anesthesiology, and endocrinology. The process of thyroidectomy was divided into three stages (preoperative -A-, operative -B- and postoperative -C-). Potential safety incidents and failures at each stage and their contributing factors (causes) were identified by literature review and brainstorming. Checklists for each checkpoint were designed by consensus of the working group. The items correspond to factors contributing to the occurrence of incidents in the perioperative stage of thyroidectomy related to patients, technological equipment, environment, management, and organization. Lists of items should be checked by the appropriate specialist in each stage. Checklists in thyroid surgery are tools that allow for testing at different checkpoints data related to factors contributing to the occurrence of failures at each stage of the care process.

    LigaSure precise (LP) and harmonic scalpel (HS) are two energy-based devices used in thyroidectomy surgery. We aimed to compare the effect of these two devices in patients who had undergone total thyroidectomy, by highlighting the post-operative parathyroid function. A total of 201 consecutive patients for whom total thyroidectomy had been planned were prospectively classified into two groups. There were 104 patients in LP group and 97 patients in HS group. Hypoparathyroidism was followed up by serially measuring the levels of intact parathyroid hormone (iPTH) and serum calcium. The early iPTH level was 29 (8-50) pg/mL in group LP, and 17 (4-43) pg/mL in group HS. The early iPTH level was significantly lower in the HS group (p parathyroid hormone levels impaired in the HS group more than LP group in the early period, these levels were in the normal limits in both groups. These levels were not significant between groups in the long time period.

    Current methods for teaching and assessing competencies that characterize expert intraoperative performance are inconsistent, subjective, and lack standardization. This mixed-methods study was designed to define and establish expert consensus on the most important competencies required to perform a thyroidectomy safely. Cognitive task analyses for thyroidectomy were performed with semistructured interviews of experts in thyroid surgery. Verbal data were transcribed verbatim, coded, and categorized according to themes that were synthesized into a list of items. Once qualitative data reached saturation, 26 experts were invited to complete 2-round online Delphi surveys to rank each item on a Likert scale of importance (1-7). Consensus was predefined as a Cronbach's α ≥ 0.80. Sixty items were synthesized from 5 interviews and categorized into 8 sections: preparation (n = 8), incision/exposure (n = 11), general considerations (n = 4), middle thyroid vein (n = 1), superior pole (n = 5), inferior pole (n = 5), posterolateral dissection (n = 19), and closure (n = 7). Eighteen (69%) experts from 3 countries participated in the Delphi survey. Consensus was achieved after 2 voting rounds (Cronbach's α = 0.95). Greatest weighted sections included "Superior Pole Dissection" and "Posterolateral Dissection." Consensus was achieved on defining the most important competencies for safe thyroidectomy. This blueprint serves as the basis for instructional design and objective assessment tools to evaluate performance. Copyright © 2016 Elsevier Inc. All rights reserved.

    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.

    The potential severity of amiodarone-induced hyperthyroidism, particularly in severe cardiopathy cases, necessitates a regular clinic and biologic thyroid control. The break in amiodarone and a medical treatment (synthetic antithyroid drugs, steroids, perchlorate of potassium) can be ineffective. The authors report the case of a patient with an right ventricle arythmogenic dysplasia, without thyroid history, who came back 3 years after the introducing of amiodarone with major hyperthyroidism. After failure of medical treatment, a total thyroidectomy permitted to quickly stop hyperthyroidism and to early reintroduce amiodarone. Surgery seems to be the radical treatment when hyperthyroidism doesn't respond to the medical treatment and when the cardiopathy requires amiodarone.

The aim of this study was to evaluate the benefits of the use of ultrasonic dissector (UAS vs. the use of a conventional technique (vessel clamp and tie in patients undergoing thyroid surgery for cancer. Methods From June 2009 to May 2010 we evaluated 321 consecutive patients electively admitted to undergo total thyroidectomy for thyroid carcinoma. The first 201 patients (89 males, 112 females presenting to our Department underwent thyroidectomy with the use of UAS while the following 120 patients (54 males, 66 females underwent thyroidectomy performed with a conventional technique (CT: vessel clamp and tie. Results The operative time (mean: 75 min in UAS vs. 113 min in CT, range: 54 to 120 min in UAS vs. 68 to 173 min in CT was much shorter in the group of thyroidectomies performed with UAS. The incidence of transient laryngeal nerve palsy (UAS 3/201 patients (1.49%; CT 1/120 patients (0.83% was higher in the group of UAS; the incidence of permanent laryngeal nerve palsy was similar in the two groups (UAS 2/201 patients (0.99% vs. CT 2/120 patients (1.66%. The incidence of transient hypocalcaemia (UAS 17/201 patients (8.4% vs. CT 9/120 patients (7.5% was higher in the UAS group; no relevant differences were reported in the incidence of permanent hypocalcaemia in the two groups (UAS 5/201 patients (2.48% vs. 2/120 patients (1.66%. Also the average postoperative length of stay was similar in two groups (2 days. Conclusion The only significant advantage proved by this study is represented by the cost-effectiveness (reduction of the usage of operating room for patients treated with UAS, secondary to the significant reduction of the operative time. The analysis failed to show any advantages in terms of postoperative transient complications in the group of patients treated with ultrasonic

    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.

    Medication with thyroid hormones following total thyroidectomy for thyroid carcinoma is based on the following principles: 1. The patient is informed about the lifelong necessity of taking a thyroid hormones daily before breakfast. This hormone must be given orally and its bioligical effect is identical with that of the tyhroid hormone secreted by the healthy thyroid gland. 2. The daily dosage of thyroid hormones may be assessed on the basis of the following parameters: a) the patient's clinical euthyroidism, b) suppression of thyrotropic activity, c) unrestricted tolerance of the preparation. 3. The in vitro parameters associated with optimal medication should be within the following ranges: Thyroxine value (TT4 or FT4): above the normal range, triiodothyronine value (TT3 or FT3): within the upper normal range and thyrotropin value (TSH 'ultrasensitive' or TRH-test): suppressed.

    The AIM OF THE STUDY was to determine postoperative insulin-resistance in patients subject to total thyroidectomy, the prevalence of subjective feelings of hunger immediately before surgery, and the incidence of nausea/vomiting after surgery in patients prepared for elective operations by means of oral glucose solutions. The study group comprised 115 patients, including 71 patients prepared for surgery by means of oral glucose solutions (12.5% glucose) administered 12 and 3 hours before the procedure, at a dose of 800 and 400 ml. The control group comprised 44 patients prepared for surgery by means of the traditional manner- the last meal was served before 2pm the day before the surgical procedure, while fluids before 10pm. Considering both groups, we evaluated glucose and insulin levels three times, as well as determined the insulin-resistance ratio (HOMA-IR) 24 before, and 12 hours and 7 days after surgery. The incidence of nausea and vomiting after surgery, and the subjective feeling of hunger before surgery were also evaluated. Statistically significant differences considering insulin level and HOMA-IR values were observed during the II and III measurements. The glucose and insulin values, and the HOMA-IR insulin-resistance ratio, showed no statistically significant differences during measurement I. No statistically significant glucose level differences were observed during measurements II and III. A significantly greater subjective feeling of hunger before surgery and nausea/vomiting afterwards were observed in the control group. The preparation of patients with oral glucose solutions decreases the incidence of postoperative (thyroidectomy) insulin-resistance, and occurrence of nausea/vomiting during the postoperative period.

    To study the risk factors for postoperative hypoparathyroidism or hypocalcemia. Totally 414 patients with thyroid diseases who underwent total or near total thyroidectomy at Department of Head and Neck Surgery, Peking University Cancer Hospital and Institute from June 2007 to June 2014 were studied retrospectively. There were 119 male and 295 female patients with a median age of 47 years. The clinical and pathological features that related to post-operative hypoparathyroidism were studied by χ(2) test and multivariate Logistic regression analysis. Of the 414 patients, 36.2% developed transient hypocalcemia, 36.5% developed transient hypoparathyroidism, 2.2% developed permanent hypoparathyroidism. In regression analysis, unilateral or bilateral center lymph node dissection were associated with mild transient hypocalcemia after surgery (OR=2.366, P=0.022; OR=5.216, P=0.000); unilateral or bilateral center lymph node dissection as well as surgical options were significant risk factors for severe transient hypocalcemia (OR=4.029, P=0.001; OR=8.384, P=0.000; OR=2.073, P=0.017) and hypoparathyroidism (OR=1.755, P=0.040; OR=4.144, P=0.000; OR=2.287, P=0.000). The parathyroid hormone concentration on postoperative day 1 was an independent risk factor for permanent hypoparathyroidism (OR=2.011, P=0.014). The concentration of parathyroid hormone threshold hypoparathyroidism with accuracy of 95.0%. Bilateral center lymph node dissection is a risk factor of permanent hypoparathyroidism in patients received total thyroidectomy should be taken thoughtfully. The parathyroid hormone concentration on postoperative day 1 provides better prediction for persistent hypoparathyroidism.

    A major morbidity after total thyroidectomy is hypocalcemia. Although many clinical factors and laboratory studies have been correlated with both biochemical and symptomatic hypocalcemia, the ideal use and timing of these tests remain unclear. We hypothesize 1-h (PACU) parathyroid hormone (PTH) will identify patients at risk for symptomatic hypocalcemia. This prospective study evaluated 196 patients undergoing total thyroidectomy. Serum calcium and PTH levels were measured 1 h after surgery and on postoperative day 1 (POD1). Performance of a central compartment lymph node dissection, parathyroid autotransplantation, indication for procedure, pathology, and presence of parathyroid tissue in the pathology specimen were recorded. Of 196 patients, nine (4.6%) developed symptomatic hypocalcemia. Thirty four (17.3%) had a 1-h PACU PTH ≤10 pg/dL, whereas 31 (15.8%) had a POD1 PTH of ≤10. Five (56%) of the nine symptomatic patients underwent central compartment lymph node dissection, four (44%) had parathyroid autotransplantation, and four (44%) had a PACU PTH ≤10. PACU and POD1 PTH levels were correlated (R(2) = 0.682). Multivariate regression identified central compartment dissection, autotransplantation, and PACU or POD1 PTH correlated with symptomatic hypocalcemia. PACU PTH, POD1 PTH, PACU Ca, malignant final pathology, and age ≤45 y correlated with biochemical hypocalcemia. A 1-h postoperative PACU PTH is equivalent to POD1 PTH in predicting the development of symptomatic hypocalcemia. Biochemical hypocalcemia was not predictive of symptoms in the immediate postoperative period. Lymph node dissection and parathyroid autotransplantation correlated with symptomatic hypocalcemia and improve the sensitivity of biochemical screening alone. Copyright © 2016 Elsevier Inc.

    Recent American Thyroid Association guidelines call for thyroidectomy or (131)I (Recommendation 31) in managing hyperthyroidism due to toxic nodular goiter (TNG). Concern for concomitant malignancy favors surgery. A 3 % thyroid cancer incidence in TNG patients has been reported, yet recent studies suggest this rate is underestimated. This multi-institutional study examined cancer incidence in TNG patients referred to surgery. Patients referred for thyroidectomy at three tertiary-care institutions were included (2002-2011). Patients with concurrent indeterminate or malignant diagnosis by fine-needle aspiration (FNA) were excluded. Cancer incidence in TNG patients was determined. Fisher's exact and chi-square tests and nonparametric t tests were used. Among 2,551 surgically treated patients, 164 had TNG (6.4 %). Median age at presentation was 49.7 years, and 86 % were female. Overall cancer incidence was 18.3 % (30 of 164), and rates were not significantly different between institutions. A significantly greater cancer rate was noted in toxic multinodular goiter versus single toxic nodule patients (21 vs. 4.5 %, P  0.05). No significant cancer association was noted with age, preoperative dominant nodule size, lymphocytic thyroiditis or preoperative FNA (P > 0.05). These data demonstrate a higher than expected incidental cancer rate in TNG patients compared to historical reports (18.3 vs. 3 %). This higher cancer incidence may alter the risk/benefit analysis regarding TNG treatment. This information should be provided to TNG patients before decision making regarding treatment.

    2017-01-01

    The most common complication of total thyroidectomy is parathyroid insufficiency. Acute, transient, post-operative hypoparathyroidism increases length of hospitalization, morbidity and cost associated with total thyroidectomy. While permanent hypoparathyroidism poses a significant medical burden with lifetime medication, regular follow up and considerable disease burden related to chronic renal failure and other sequelae. Parathyroid autotransplantation has been demonstrated to result in biochemically functional grafts, leading to the procedures’ common use during total thyroidectomy. The clearest indications for parathyroid auto transplantation are inadvertently removed or devascularized parathyroid glands. Some centers utilize routine autotransplantation to reduce the risk of permanent hypoparathyroidism. Novel fluorescence techniques to aid in parathyroid detection during thyroid surgery are under evaluation. This review aims to define the role and impact of parathyroid autotransplantation undertaken during total thyroidectomy. PMID:29322025

The peri- and postoperative complications are higher in total thyroidectomy (TT for SG than that for cervical goiter. The aim of this study was to evaluate the preoperative risk factors associated with postoperative complications. From 2002 to 2014, 142 (8.5%; 98 women and 44 men of the 1690 patients who underwent TT had a SG. We retrospectively evaluated the following parameters: sex, age, histology, pre- and retrovascular position, recurrence, and extension beyond the carina. These parameters were then related to the postoperative complications: seroma/hematoma, transient and permanent hypocalcemia, transient and permanent laryngeal nerve palsy, and the length of surgery. The results were further compared with a control group of 120 patients operated on in the same period with TT for cervical goiter. All but two procedures were terminated via cervicotomy, where partial sternotomies were required. No perioperative mortality was observed. Results of the statistical analysis (Student’s t-test and Fisher’s exact test indicated an association between recurrence and extension beyond the carina with all postoperative complications. The group that underwent TT of SG showed a statistically significant higher risk for transient hypocalcemia (relative risk =1.767 with 95% confidence interval: 1.131–2.7605, P=0.0124, and need to treat =7.1 and a trend toward significance for transient recurrent laryngeal nerve palsy (relative risk =6.7806 with 95% confidence interval: 0.8577–53.2898, P=0.0696, and need to treat =20.8 compared to the

We retrospectively analysed the relation of serum thyroglobulin concentration and the post-surgical status of thyroid in patients with papillary or follicular thyroid cancer. 321 patients who underwent thyroidectomy due to thyroid cancer were included in this study. They were divided into groups such as group-1 (no metastases), group-2 (neck lymph node metastases) and group-3 (distant metastases) as well as subgroup of lung, bone and combined lung and bone metastases. All the patients were asked to stop T4 for 6 weeks and T3 for 2 weeks before performing a whole body scan with 2 mCi of radioiodine-131. Radioimmuno-assay measurement of FT3, FT4, TSH, serum thyroglobulin (Tg) and serum anti-thyroglobulin antibody (TgAb) was also done. Mean serum Tg concentration in patients with follicular cancer was higher than that of papillary but there was not statistically significant difference (p>0.05). However, there was a significant difference in mean serum Tg concentration between distal metastases group and no metastases group as well as neck lymph node metastases group (p 0.05). In general, serum Tg concentration was proportionate to the amount of functional thyroid tissue remaining in the neck or metastatic sites in the body. Although conventional diagnostic methods such as ultrasound, X-ray, bone scan were helpful to detect and evaluate the progression of thyroid cancer, but were poor indicators for detecting micro-metastases in early stage. Therefore, it is very important to combine the above-mentioned method with serum Tg measurements. In conclusion serum thyroglobulin measurement was really

    Full Text Available CONTEXT AND OBJECTIVE: Magnesium ion concentration is directly related and phosphorus ion concentration is inversely related to calcemia. The aim of this study was to evaluate the evolution of magnesium and phosphorus ion levels in patients undergoing thyroidectomy and correlate these with changes to calcium concentration. DESIGN AND SETTING: Prospective study at the Alpha Institute of Gastroenterology, Hospital das Clínicas, Universidade Federal de Minas Gerais. METHODS: The study included 333 patients, of both genders and mean age 45 ± 15 years, who underwent thyroidectomy between 2000 and 2005. Total calcium, phosphorus and magnesium were measured in the blood preoperatively and 24 and 48 hours postoperatively. Ionic changes were evaluated according to the presence or absence of postoperative hypocalcemia. RESULTS: There were statistically significant drops in blood phosphorus levels 24 and 48 hours after thyroidectomy, compared with preoperative values, in the patients without hypocalcemia. In the patients who developed hypocalcemia, there was a significant drop in plasma phosphorus on the first postoperative day and an increase (also statistically significant on the second day, in relation to preoperative phosphorus levels. A significant drop in postoperative magnesium was also observed on the first and second days after thyroidectomy in the patients with hypocalcemia, in relation to preoperative levels. In the patients without hypocalcemia, the drop in magnesium was significant on the first day, but there was no difference on the second day. CONCLUSION: Despite the postoperative changes, neither magnesium nor phosphorus ion levels had any role in post-thyroidectomy calcemia.

    A permanent hypoparathyroidism is a problematic complication of total thyroidectomy. In this study, we investigated its incidence and how to avoid it at the time of completion total thyroidectomy after hemithyroidectomy. Eight of the 154 patients who underwent completion total thyroidectomy as the second surgery (5%) after hemithyroidectomy (two-surgery group) showed a permanent hypothyroidism. Patients without parathyroid autotransplantation either at initial or second surgery were more likely to show a permanent hypoparathyroidism. In the subset of 74 patients in two-surgery group, who underwent bilateral central dissection, 6 (8%) had a permanent hypoparathyroidism. The incidence was higher than those in control group who underwent total thyroidectomy with bilateral central dissection at one time, which was 2%. However, all 6 patients showing a permanent hypoparathyroidsm underwent bilateral central dissection in initial surgery and none of the patients who underwent bilateral central dissection in twice had a permanent hypoparathyroidism. Taken together, we can conclude that 1) in initial surgery of hemithyroidectomy, we have to carefully search the parathyroid glands and if dissected, they should retrieved and autotransplanted to save the patients from a permanent hypoparathyroidism when they undergo second surgery in future, and 2) hemithyroidectomy with bilateral central dissection significantly increases the risk of permanent hypoparathyroidism and only ipsilateral dissection is better when we do not perform total thyroidectomy.

    Postoperative hypocalcemia caused by hypoparathyroidism is one of the most common morbidities of total thyroidectomy. The aim of this study was to analyze the kinetics and factors affecting PTH levels after total thyroidectomy and central neck dissection (CND). We performed a retrospective study in 438 consecutive patients who underwent total thyroidectomy between January 2007 and December 2010. No patient had a history of thyroid or neck surgery. PTH and calcium levels were recorded 1 day before the operation, during the first 5 days, and during follow-up (2 weeks and 2, 6, and 12 months). PTH levels declined to 41.90% of its initial value on the first day after the operation. After surgery, PTH was correlated positively with calcium and inversely with phosphate levels from postoperative day 1 to 14. Based on clinical observation, using a PTH threshold of hypoparathyroidism, with sensitivity and negative predictive value 100%, but poor specificity (70.19%). CND increased the risk of transient hypoparathyroidism compared with total thyroidectomy alone. Patients with thyroiditis had an increased risk of permanent hypoparathyroidism compared with those without thyroiditis. Iatrogenic removal of the parathyroid glands increased the risk of permanent hypoparathyroidism compared with those without iatrogenic parathyroidectomy. PTH declined on the first day after thyroidectomy. PTH levels hypoparathyroidism. CND, thyroiditis, and iatrogenic parathyroidectomy increased the risk of hypoparathyroidism.

    Amiodarone is a potent antiarrhythmic agent, indicated for the treatment of refractory arrhythmias, which may lead to thyrotoxicosis. In these patients, thyroidectomy is a valid therapeutic option. Antithyroid therapy in the immediate preoperative setting and the subsequently accepted minimal delay until thyroidectomy have not been clearly defined yet. The aim of the present study was to show, that total thyroidectomy under general anaesthesia in patients with amiodarone-induced thyrotoxicosis (AIT) is safe without necessarily obtaining an euthyroid state preoperatively.We conducted a retrospective cohort study of prospectively gathered data on 11 patients undergoing total thyroidectomy under general anaesthesia between January 2008 and December 2013 for AIT at our University Hospital.All patients were preoperatively treated with carbimazole, steroids and β-receptor antagonists. Additionally, 3 patients received potassium perchlorate and in one patient carbimazole was changed to propylthiouracil. Plasmapheresis was performed in 3 patients. Only one patient was euthyroid at the time of operation. There were no significant intra- and postoperative complications, especially no signs of thyroid storm. One patient could postoperatively be removed from the cardiac transplant waiting list due to improved cardiac function.Improvements in the interdisciplinary surgical management for AIT between cardiologists, endocrinologists, anaesthetists and endocrine surgeons provide the basis of safe total thyroidectomy under general anaesthesia in hyperthyroid state. Early surgery without long delay for medical antithyroid treatment (with its potential negative side effects) is recommended. © Georg Thieme Verlag KG Stuttgart · New York.

    A 57 year old female came with the complaint of recurrent headache, often fatigue, and sometimes feel numbs and rigid in her extremities, no other symptom was noted. Her body weight is stable and she was in menopausal state. She had a history of partial thyroidectomy 20 years ago and continues thiamazole 2.5 mg with seldom regular consult to physician. From the physical examination, the patient had a scar from thyroid surgery and other organs were in the normal condition. From laboratory examination, there was slight normocytic normochromic anemia (Hb: 10.7 gr/dL), normal fT4: 1.21 ng/dL (0.7-1.48 ng/dL), slightly low Calcium: 8.3 mg/dL (8.5-10.2 mg/dL), others were within normal limit but there was no Phosphorus level data. She was currently on medication: thiamazole 2.5 mg once daily, CaCO3 500 mg once daily, and alfacalcidol 1 mcg once daily, to prevent the rigid and numbness that she felt before. For further investigation, we performed a PTH test with result of hypoparathyroidism with parathyroid hormone 7 pg/mL (15-65 pg/mL) and brain CT-scan with result there was a symmetrical bilateral calcification in radiate corona, frontal lobes, temporal lobes, basal ganglia, thalamic, and dentate nuclei of cerebelli. There was no data about the histopathology examination of the thyroid tumor because the patient did not keep the data. The mechanism of intracranial calcification in hypoparathyroidism, more often seen in pseudohypoparathyroidism than in idiopathic hypoparathyroidism, has not been completely elucidated. It may be related more to the duration of hypocalcaemia and hyperphosphataemia than parathyroid hormone itself. Hyperphosphataemia promotes ectopic calcification in brain tissue in hypoparathyroidism. Intracranial calcification is one of the features of chronic hypocalcemia, and the calcifications typically involve basal ganglia, thalami, and the cerebellum.

    Abstract Cervical spondylosis is degeneration of the cervical spine that occurs during the normal course of aging, and may progress into compression of the spinal cord, or cervical spondylotic myelopathy (CSM), which can cause neurologic dysfunction. Cervical spondylosis can be identified in the majority of people older than 50 years. Many people with cervical spondylosis or CSM are asymptomatic. However, patients with CSM are at higher risk of spinal cord injury (SCI) following minor injury. A 60-year-old woman with asymptomatic cervical spondylosis underwent an elective subtotal thyroidectomy for thyroid nodules. After the surgery, she developed tetraplegia. MRI revealed spinal cord compression and injury. Main diagnoses, therapeutics interventions, and outcomes: Acute cervical SCI was diagnosed. After an emergency anterior cervical corpectomy and fusion surgery, she almost completely recovered. Iatrogenic cervical SCI after nonspinal surgeries that requires neck hyperextension is rarely reported, probably due to underdiagnosis and underreport. Among the 14 cases (including ours) published in the literature, most patients had cervical spondylosis and were senior men. Five patients had diabetes. Four patients had long-term hemodialysis. Seven patients had undergone coronary artery bypass surgery that requires prolonged operative time. Only 3 patients had almost complete recovery. Most patients were disabled. Two patients required tracheostomy for long-term ventilator support. Two patients died. These cases reiterate the potential risk of iatrogenic SCI in people with predisposing conditions such as cervical spondylosis, especially considering the rising prevalence and severity of cervical spondylosis caused by the aging of the population and modern sedentary lifestyle. Surgeries requiring prolonged neck hyperextension put patients with cervical spondylosis at risk for SCI. Failure to recognize the potential occurrence of iatrogenic SCI might endanger patients

  8. Features of Mineral Metabolism Disorders in Patients with Multinodular Goiter after Thyroidectomy

    2015-08-01

    Full Text Available The features of calcium, phosphorus, parathyroid hormone and vitamin D indexes in patients with multinodular non-toxic goiter after thyroidectomy are presented in the article. It is found that age over 60 years, greater thyroid volume, lower 25(ОНD level before surgery, decline of parathyroid hormone level after surgery are the basic parameters that influence the development of hypocalcemia in patients with multinodular goiter after thyroidectomy. The level of 25(OHD below 20 ng/ml should be regarded as a specific and sensitive preoperative predictor of hypocalcemia after thyroidectomy, as well as persistent hypoparathyroidism. The level of parathyroid hormone after surgery below 10 pg/ml can be considered as a predictor of these conditions.

    Whether thyroidectomy for metastases to the thyroid is associated with a survival benefit remains debatable; in general, palliation and disease control are accepted goals in this setting. We evaluated the clinical features and overall survival of patients with thyroid metastasis treated by thyroid resection or nonoperatively. This retrospective analysis included 90 patients identified with metastasis to the thyroid confirmed pathologically via thyroidectomy (n = 31) or fine-needle aspiration biopsy (n = 59). Overall survival was calculated by the Kaplan-Meier method, and differences between groups were calculated by Pearson's χ (2) coefficient. The most common primary malignancies were renal cell (20%), head and neck (19%), and lung (18%). The median time from primary tumor diagnosis to thyroid metastasis diagnosis was 37.4 months (range 0-210 months). Most metastases (69%) were metachronous, and 12% were isolated. The median follow-up after diagnosis of thyroid metastasis was 11.5 months (range 0-112 months). Median overall survival was longer in thyroidectomy patients compared to the fine-needle aspiration group (34 vs. 11 months, P renal cell primary tumors were more likely to undergo thyroidectomy than patients with other primary tumors (78 vs. 24%, P thyroid metastasis diagnosis, and thyroidectomy was only offered to three patients. Thyroidectomy was safe for selected patients with metastatic disease to the thyroid. Patients with metachronous or renal cell metastasis to the thyroid and whose primary tumor is/was treatable may be appropriate candidates for resection. Lung cancer metastasis to the thyroid is generally an ominous sign.

    In seventy patients with nodular thyroids and a history of radiation exposure, total thyroidectomy disclosed a 54 percent incidence of carcinoma; more than half of them had cervical node metastases; four had distant metastases. Fourteen patients required radical neck dissection. The carcinoma was multicentric (both lobes) in 45 percent. In four patients the carcinoma was found in the lobe contralateral to the one containing the palpable nodule. These findings support the advocates of total thyroidectomy for patients with a nodular thyroid and a history of radiation exposure, provided this operation can be performed with a low incidence of recurrent nerve palsy and hypoparathyroidism.

    Full Text Available Total thyroidectomy involving the adjacent structures of the trachea can cause tracheal damage such as early tracheal necrosis. The authors describe the first case of anterior tracheal necrosis following total thyroidectomy treated using vacuum-assisted closure device. After two weeks of VAC  therapy, there was no evidence of ongoing infection and the trachea was partially closed around a tracheotomy cannula, removed after 3 months. The use of a VAC  therapy to reduce and close the tracheal rent and to create a rapid granulation tissue over tracheal structure appeared as a good opportunity after anterior tracheal necrosis.

    Full Text Available Anaplastic thyroid carcinoma (ATC is a rare and highly aggressive thyroid neoplasm. Bleeding from tumor is an uncommon, but potentially life-threatening complication requiring sophisticated intervention facilities which are not usually available at odd hours in emergency. We report the case of a 45-year-old woman who presented with exsanguinating hemorrhage from ATC and was treated by emergency total thyroidectomy. The patient is well three months postoperatively. Emergency total thyroidectomy is a viable option for palliation in ATC presenting with bleeding.

    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.

    Postoperative pain for robotic thyroid surgeries including bilateral axillo-breast approach (BABA) has not been well studied. In this study, we have developed a self-reporting application (SRA) for iPad and prospectively collected pain scores from open thyroidectomy (OT) and BABA robotic thyroidectomy (RT) patients. Female patients who underwent total thyroidectomy for papillary thyroid carcinoma were included. Patients recorded pain scores for throat, anterior neck, posterior neck, chest, and back on postoperative days 1, 2, and 3. Once discharged, on postoperative day 14, a survey was also conducted on satisfaction of SRA and cosmesis. A total of 54 patients were enrolled (27 BABA RT and 27 OT). There were no significant differences between the 2 groups in clinicopathological characteristics and postoperative complication rates. Postoperative pain scores at days 1, 2, 3, and 14 were not significantly different between the groups for throat, anterior neck, posterior neck, or back. Postoperative analgesic requirements were similar between the 2 groups. Wound satisfaction scores were significantly higher in the BABA RT group (BABA RT 7.4 vs. OT 5.7; P = 0.016). Satisfaction scores for the usefulness of SRA were above 7.2 for all four questionnaire items on the 10-point scale. Postoperative pain for BABA RT is equivalent to OT but offers greater cosmetic satisfaction for patients. A mobile device application such as SRA may facilitate proper assessment and management of pain in postoperative patients.

    Previous studies have established the efficacy of post-thyroidectomy hypocalcemia monitoring using parathyroid hormone (PTH) and corrected calcium levels at 1 and 6 hours. The goal of this study was to measure the impact of managing patients based on the above findings with respect to: duration of hospital stays, rates of transient hypocalcemia, number of blood tests, cost savings, and discharge from the hospital as early as 8 hours post-thyroidectomy without compromising safety. This is a prospective study involving 95 total thyroidectomy patients using historical data as controls. The previous protocol was modified in that all blood tests ceased for patients meeting the 6-hour critical level of PTH > or = 28 ng/L and simultaneous corrected calcium > or = 2.14 mmol/L (8.56 mg/dL). Furthermore, patients with 1-hour PTH levels cost savings of 766 Canadian dollars per patient. The new algorithm resulting from PTH and corrected calcium monitoring at 1 and 6 hours post-thyroidectomy has led to significant cost savings for our institution. It has also translated into greater patient satisfaction as a result of fewer blood tests, a lower incidence of transient hypocalcemia, and significantly shorter hospital stays.

    Hypocalcaemia is the most common adverse effect after total thyroidectomy. It recovers in about two-thirds of the patients within the first postoperative month. Little is known, however, about recovery of the parathyroid function (RPF) after this time period. The aim of the present study was to investigate the time to RPF in patients with protracted (>1 month) hypoparathyroidism after total thyroidectomy. Cohort prospective observational study. Adult patients undergoing total thyroidectomy for goitre or thyroid cancer. Cases with protracted hypoparathyroidism were studied for RPF during the following months. Time to RPF and variables associated with RPF or permanent hypoparathyroidism were recorded. Out of 854 patients undergoing total thyroidectomy, 142 developed protracted hypoparathyroidism. Of these, 36 (4.2% of the entire cohort) developed permanent hypoparathyroidism and 106 recovered: 73 before 6 months, 21 within 6-12 months and 12 after 1 year follow-up. Variables significantly associated with RPF were the number of parathyroid glands remaining in situ (not autografted nor inadvertently resected) and a serum calcium concentration >2.25 mmol/L at one postoperative month. Late RPF (>6 months) was associated with surgery for thyroid cancer. RPF was still possible after one year in patients with four parathyroid glands preserved in situ and serum calcium concentration at one month >2.25 mmol/L. Permanent hypoparathyroidism should not be diagnosed in patients requiring replacement therapy for more than six months, especially if the four parathyroid glands were preserved. © 2018 European Society of Endocrinology.

    Postoperative hypocalcemia is a common complication of thyroidectomy. Magnesium is known to modulate serum calcium levels and hypomagnesemia may impede correction of hypocalcemia. The purpose of this study was to investigate whether hypomagnesemia after thyroidectomy has any impact on early hypocalcemia and/or permanent hypoparathyroidism. We conducted a retrospective review of prospectively maintained databases. Inclusion criteria were total or completion total thyroidectomy with postoperative magnesium levels available. The incidence of postoperative hypocalcemia was correlated with postoperative hypomagnesemia and other risk factors. Two hundred one cases were included. Twenty-six patients (13%) developed postoperative hypomagnesemia. Hypomagnesemia (p = .002), cancer diagnosis (p = .01), central neck dissection (p = .02), and inadvertent parathyroid resection (p = .02) were significantly associated with hypocalcemia. On multivariate analysis, only hypomagnesemia (p = .005) remained significant. Hypomagnesemia was also a significant predictor of permanent hypoparathyroidism (p = .0004). Hypomagnesemia is significantly associated with early hypocalcemia and permanent hypoparathyroidism after thyroidectomy. Magnesium levels should be closely monitored in patients with postthyroidectomy hypocalcemia. © 2015 Wiley Periodicals, Inc.

    The aim of this study is to analyze our preliminary results from minimally invasive video-assisted thyroidectomy (MIVAT) and demonstrate the feasibility of MIVAT also in non-referral centers. We report our initial experience based on a series of 47 patients selected for MIVAT at General Surgery Department of University of Trieste during a period from May 2005 to February 2007. The eligibility criteria were rigorously observed. Age, goiter volume, major diameter of the dominant nodule, operative times, pathologic findings, postoperative pain, length of hospital stay, cosmetic results, and complications were retrospectively analyzed. Thyroid lobectomy was successfully accomplished in 33 cases, total thyroidectomy in 14. Conversion to standard cervicotomy was required in three patients (6%). Mean operative time of lobectomy was 82.6 min and 118.7 for total thyroidectomy. Postoperative complications included 11 (23.4%) transient hypocalcemias, 2 (4.2%) hematomas, and 2 (4.2%) temporary laryngeal nerve palsies. None-recurrent nerve palsies was observed. The cosmetic result was excellent in most cases. Our experience demonstrates that MIVAT, after adequate training, is feasible and safe, with results comparable to conventional thyroidectomy, also in a General Surgery Department, from a dedicated team, with a sufficient and specific activity volume.

    Full Text Available Background. Cutting the sternothyroid (ST muscle is a useful technique to expose the superior pole of thyroid gland during thyroidectomy. In this study, we evaluated the impact of partial cutting of the ST muscle on postoperative vocal outcomes after total thyroidectomy. Methods. A retrospective review of 57 patients who underwent total thyroidectomy with central neck dissection for micropapillary thyroid carcinoma was conducted. Group A (n=26 included those without cutting the ST muscle, while group B (n=31 included patients whose muscle was partially cut at the superior pole. All patients underwent voice analysis before the operation and 2 weeks and 1 month after the surgery, and the outcomes were compared between the two groups. Results. There were no differences between the two groups regarding the outcomes at each time of voice analysis. Group A showed a decrease of maximum frequency 2 weeks after surgery but showed no difference after 1 month. Group B showed a mild decrease in maximum frequency 2 weeks after surgery, but the difference was not significant. Conclusion. Partial cutting of ST muscle during thyroidectomy is useful to expose the superior pole without significant negative impact on postoperative outcomes of vocal analysis.

    To prevent hypoparathyroidism after thyroidectomy, preservation of the parathyroid glands and their vascularity are essential. The aim of this study was to determine the association between postoperative parathyroid function and the viability of the parathyroid glands during thyroidectomy. We prospectively analyzed 111 patients who underwent total thyroidectomy and in whom all 4 parathyroid glands were preserved in situ during the operation. The surgeons scored the viability of each parathyroid gland from 0 (normal) to 3 (severely compromised viability) based on its gross appearance and vascularity intraoperatively. The index of parathyroid viability score (IPVS) was defined as the sum of the viability scores of the 4 parathyroid glands. We evaluated the relationship between postoperative parathyroid function and IPVS. Transient hypoparathyroidism occurred in 25 patients (22.5%), and permanent hypoparathyroidism in 4 patients (3.6%). The IPVS were significantly different in the three groups: 2.87±1.46 in the normal group, 3.68±1.41 in the transient hypoparathyroidism group and 7.50±1.00 in the permanent hypoparathyroidism group. The rates of transient hypoparathyroidism were 13.6% in patients with IPVS 0-2, 23.8% in patients with IPVS 3-4, and 42.9% in patients with IPVS 5-6. All the patients with IPVS of 7 or more had permanent hypoparathyroidism. IPVS is correlated with the incidence of hypoparathyroidism. It could be a good quantitative indicator of the probability of hypoparathyroidism after thyroidectomy.

    1) Determine the safety of outpatient thyroidectomy in the geriatric patient population. 2) Analyze the risk of postoperative complications from thyroid surgery in patients aged over 65 years (elderly) and aged over 80 years (super-elderly) undergoing ambulatory thyroidectomy compared to patients aged 21 through 40 years. A retrospective analysis of consecutive patients undergoing thyroidectomy between January 2008 and July 2015 at a tertiary academic institution. Patients were stratified by age, and three subsets within this population were considered and analyzed further: youthful/control (aged 21-40 years), elderly (aged 65-79 years), and super-elderly (≥ 80 years). Patient demographics, surgical and pathological data, admission status, complication, and readmission rates were recorded. A total of 1,429 thyroidectomies were accomplished; of these, 1,207 (84.5%) were outpatient operations. Among the outpatients, 85.2% were female, 14.1% were male, and the mean age was 50.3 ± 15.2 years. The control (youthful) group was comprised of 328 patients with a mean age of 33.3 years; the elderly group of 201 patients had a mean age of 70.3 years; and 16 patients in the super-elderly group had a mean age 82.7 years. The complication rates (5.2%, 5.0%, and 6.3%, respectively; P = 0.98) and re-admission rates (1.5%, 1.5%, and 0.0%, respectively; P = 0.89) were not different among these groups. Outpatient thyroid surgery is as safe in appropriately selected elderly and super-elderly patients as it is in a control group of youthful patients. Therefore, age should not be a contraindication to conducting thyroidectomy on an ambulatory basis. 4.

    Full Text Available Background: Hypocalcemia is one of the most prevalent complications following total thyroidectomy. Over recent years, in addition to hormone parathyroid hormone (PTH, vitamin D has been also studied as a factor causing post-total thyroidectomy hypocalcemia. This survey seeks to study the relationship between the serum level of vitamin D before surgery and during post-total thyroidectomy hypocalcemia. Methods: A group of 57 patients volunteering for total thyroidectomy were studied on Vali-e-Asr Hospital, Tehran, Iran, from March 2013 to March 2015. In all these patients, pre-surgery calcium, vitamin D and parathyroid hormone (PTH as well as the level of calcium during the post-surgery first two days were measured. Based on objectives of this study, the relationship be-tween pre-surgery vitamin D level and post-surgery hypocalcemia was examined. Results: The average age of patients participating in the survey was 24.1±13.3. They included 19 women (33.3% and 38 men, total of 40 patients (70.2%. Their average post-surgery calcium level was 9.2±0.77 milligrams per deciliters (mg/dl and their average vitamin D content before the surgery was 42±12.1 nanomole per liter (nmol/l. The average calcium level before the surgery and the first post-surgery day were meaningfully different in terms of statistics (P0.001. Of 37 patients with pre-surgery vitamin D deficiency, 31 suffered post-surgery second-day hypocalcemia and of 20 patients with vitamin D insufficiency, 18 suffered second-day hypocalcemia. This difference was not statistically meaningful either (P>0.001. Conclusion: The current study showed that the serum level of vitamin D before total thyroidectomy does not have any role in the occurrence of post-surgery hypocalcemia which is almost common after this type of surgery.

  6. Determinants of operative time in thyroid surgery: A prospective multicenter study of 3454 thyroidectomies.

    Full Text Available To identify the determinants of operative time for thyroidectomy and quantify the relative influence of preoperative and intra-operative factors.Anticipation of operative time is key to avoid both waste of hospital resources and dissatisfaction of the surgical staff. Having an accurate and anticipated planning would allow a rationalized operating room use and may improve patient flow and staffing level.We conducted a prospective, cross-sectional study between April 2008 and December 2009. The operative time of 3454 patients who underwent thyroidectomy performed by 28 surgeons in five academic hospitals was monitored. We used multilevel linear regression to model determinants of operative time while accounting for the interplay of characteristics specific to surgeons, patients, and surgical procedures. The relative impact of each variable on operative time was estimated.Overall, 86% (99% CI 83 to 89 of operative time variation was related to preoperative variables. Surgeon characteristics accounted for 32% (99% CI 29 to 35 of variation, center location for 29% (99% CI 25 to 33, and surgical procedure or patient variables for 24% (99% CI 20 to 27. Operative time was significantly lower among experienced surgeons having practiced from 5-19 years (-21.8 min, P<0.05, performing at least 300 thyroidectomies per year (-28.8 min, P<0.05, and with increasing number of thyroidectomies performed the same day (-11.7min, P<0.001. Conversely, operative time increased in cases of procedure supervision by a more experienced surgeon (+20.0 min, P<0.001. The remaining 13.0% of variability was attributable to unanticipated technical difficulties at the time of surgery.Variation in thyroidectomy duration is largely explained by preoperative factors, suggesting that it can be accurately anticipated. Prediction tools allowing better regulation of patient flow in operating rooms appears feasible for both working conditions and cost management.

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

    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

    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.

    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.

    Objective: To determine the validity of early (one hour postoperatively) parathyroid hormone (PTH) assay (10 pg/ml), keeping gold standard as the serum ionic calcium level, for predicting sub-total thyroidectomy-related hypocalcaemia and to calculate the sensitivity and specificity of latent signs of tetany. Study Design: Cross-sectional validation study. Place and Duration of Study: Department of General Surgery, Pakistan Institute of Medical Sciences, Islamabad from August 2008 to August 2010. Methodology: Patients undergoing sub-total thyroidectomy were included by convenience sampling. PTH assay was performed 1 hour post sub-total thyroidectomy. Serum calcium levels were performed at 24 and 48 hours, 5th day and 2 weeks after surgery. Cases that developed hypocalcaemia were followed-up for a period of 6 months with monthly calcium level estimation to identify cases of permanent hypocalcaemia. Symptoms and signs of hypocalcaemia manifesting in our patients were recorded. Data was analyzed through SPSS version 10. 2 x 2 tables were used to calculate sensitivity and specificity of PTH in detecting post-thyroidectomy hypocalcaemia. Results: Out of a total of 110 patients included in the study, 16.36% (n=18) developed hypocalcaemia including 1.81% (n=2) cases of permanent hypoparathyroidism. The sensitivity of one hour postoperative PTH assay as a predictive tool for post-thyroidectomy related hypocalcaemia was 94.4% while its specificity was 83.6% with 53% positive predictive value and 98.7% negative predictive value. Conclusion: One hour post sub-total thyroidectomy PTH assay can be helpful in predicting post sub-total thyroidectomy hypocalcaemia. Moreover, it can be useful in safe discharge of day-care thyroidectomy patients. (author)

    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.

    Hypocalcemia is a common complication after total thyroidectomy. Previous bariatric surgery could be a higher factor risk for hypocalcemia due to alterations in calcium absorption and vitamin D deficiency. To evaluate incidence and factors involved in the risk of hypocalcemia (transient and permanent) and the postoperative outcomes of these patients after total thyroidectomy. University hospital in Paris, France. All patients who had previously undergone obesity surgery (i.e., Roux-en-Y gastric bypass, sleeve gastrectomy, or adjustable gastric band) who had a total thyroidectomy from 2006 to 2015 were included. No patient was lost to follow-up. Each patient was matched 1:1 with a patient who had no previous bariatric surgery for age, gender, body mass index, and year of surgery. Forty-eight patients were identified (43 female; mean age 48.9±9.2 yr). Nineteen patients (40%) had a postoperative hypocalcemia: transient in 14 patients (29.2%) and permanent in 5 patients (10.4%). No significant predictive clinical or biochemical factors were found for hypocalcemia risk, except for the type of bariatric procedure: Bypass surgery had a 2-fold increased risk of hypocalcemia compared to others procedures (60% versus 30%, P = .05). In the matched pair analysis, the risk of hypocalcemia was significantly higher in patients with previous bariatric surgery than in the matched cohort (40% versus 15%, P = .006). Patients with previous bariatric surgery have an increased risk for hypocalcemia after total thyroidectomy, especially after Roux-en-Y gastric bypass. Careful and prolonged follow-up of calcium, vitamin D, and parathyroid hormone levels should be suggested for these patients. Copyright © 2017 American Society for Bariatric Surgery.

    Parathyroid autotransplantation during total thyroidectomy leads to higher rates of postoperative hypocalcaemia. It has been argued, however, that it prevents permanent hypoparathyroidism. The impact of autografted normal parathyroid gland fragments on long-term parathyroid status has not been assessed properly. To clarify this, the short- and long-term parathyroid function was assessed in patients with three glands remaining in situ after total thyroidectomy, in whom the fourth gland was either autotransplanted (Tx) or accidentally resected (AR). Consecutive patients (n = 669) undergoing first-time total thyroidectomy were prospectively studied recording the number of parathyroid glands remaining in situ: PGRIS =4-(glands autografted + glands in the specimen). The study was focused on the subgroup of 186 patients with three parathyroid glands remaining in situ as a result of either accidental resection (AR, n = 76) or autotransplantation into the sternocleidomastoid muscle (Tx, n = 110). Prevalence of postoperative hypocalcaemia, protracted, and permanent hypoparathyroidism were compared between the two groups. Demographic, disease-related, laboratory, and surgical variables were recorded. All patients were followed for at least 1 year. Both groups were comparable in terms of disease and extent of surgery. Mean postoperative serum calcium was the same (AR: 1.97 ± 0.2 vs Tx: 1.97 ± 0.22 mmol/L). Rates of protracted (AR: 24% vs Tx: 25.5%) and permanent hypoparathyroidism (AR: 5.3% vs Tx: 7.3%) were similar in both groups. The prevalence of parathyroid failure syndromes after total thyroidectomy was similar whether a parathyroid gland was inadvertently excised or autotransplanted. Autotransplantation did not influence the permanent hypoparathyroidism rate.

    A comprehensive assessment has not been undertaken of long-term outcomes in children carrying germline RET mutations and undergoing prophylactic thyroidectomy with the aim of preventing medullary thyroid cancer (MTC). A retrospective outcome study (1994-2017) of prophylactic thyroidectomy in children, with and without central node dissection, was performed at a tertiary surgical centre. Some 167 children underwent prophylactic thyroidectomy, 109 without and 58 with concomitant central node dissection. In the highest-risk mutational category, MTC was found in five of six children (83 per cent) aged 3 years or less. In the high-risk category, MTC was present in six of 20 children (30 per cent) aged 3 years or less, 16 of 36 (44 per cent) aged 4-6 years, and 11 of 16 (69 per cent) aged 7-12 years (P = 0·081). In the moderate-risk category, MTC was seen in one of nine children (11 per cent) aged 3 years or less, one of 26 (4 per cent) aged 4-6 years, three of 26 (12 per cent) aged 7-12 years, and seven of 16 (44 per cent) aged 13-18 years (P = 0·006). Postoperative hypoparathyroidism was more frequent in older children (32 per cent in the oldest age group versus 3 per cent in the youngest; P = 0·002), whether or not central node dissection was carried out. Three children developed recurrent laryngeal nerve palsy; all had undergone central node dissection (P = 0·040). All complications resolved within 6 months. Postoperative normalization of calcitonin serum levels was achieved in 114 (99·1 per cent) of 115 children with raised preoperative values. No residual structural disease or recurrence was observed. Early prophylactic thyroidectomy is a viable surgical concept in experienced hands, sparing older children the postoperative morbidity associated with delayed neck surgery. © 2018 BJS Society Ltd Published by John Wiley & Sons Ltd.

    Objective: To investigate the effects of some factors on recurrence after thyroidectomy of differentiated thyroid carcinoma (DTC). Methods: Three groups of DTC cases were studied during follow-up. All cases (n=298) of group 1 with diagnosed recurrence were analyzed statistically on age, gender, thyroid-operating mode and pathologic nature at first diagnosis. One hundred and eight cases of group 2 had received thyroid hormone-replaced therapy and 124 cases of group 3 had received thyroid hormone-replaced plus 131 I ablating therapy after thyroidectomy, and were analyzed and compared statistically by their therapeutic outcomes. Results: 1) From group 1, the ratios of male/female (1:1.5) and follicular/papillary (1:4) were higher than primary cases reported in literatures (1:2-3 and 1:8). The recurrence rates in the cases had primary lesion excised, unilateral thyroid or bilateral thyroid excised were decreased 47.3%, 34.2% and 18.5%, respectively. Recurrence mainly occurred at first 5 years after thyroidectomy (65.1%). 2) From group 2, recurrence rates were 4.63%, 8.33% and 12.04%, respectively at 1, 5 and 10 years, and 53.84% and 30.77%, respectively as local recurrence and distant metastases. From group 3, recurrence rates were 0.81%, 4.03% and 7.26%, respectively in 1, 5 and 10 years, and 5/9 and 2/9 as local recurrence and distant metastases, respectively. The statistic difference was significant (P 131 I ablating therapy after thyroidectomy may improve the prognosis of DTC (prolonging recurrence-free time, reducing recurrence rate and decreasing distant metastases).

    Full Text Available Among the patients suffering from hyperthyroidism 60-80% have Graves' disease. The initial therapy of Graves's disease are antithyroid drugs. If the remission is not achieved after 12-18 months, the patients should be directed to surgical treatment or to the therapy with radioactive iodine. The aim of this study was to compare cost/effectiveness ratios for radioactive iodine and total thyroidectomy. The analysis was made using Markov model, from the perspective of Republic Fund for Health Insurance in Serbia. Duration of one cycle in the model is six months, and the time horizon is 30 years. Monte Carlo simulation was performed for 1000 virtual patients as well as the analysis of sensitivity with the variation of parameters ± 50%. For total thyroidectomy the insurance should provide 138.389,72 RSD / 57, 83 QALY i.e. 2.393,04 dinars for one quality-adjusted life year, and for radioactive iodine the insurance should provide 110.043,64 RSD / 57,82 QALY i.e. 1.903,37 dinars for one quality-adjusted life year. This economic analysis showed that radioactive iodine has better ratio of costs to clinical effectiveness as opposed to total thyroidectomy.

    The main objective of this study is to investigate the outcome between surgical procedures and the risk of development of hypoparathyroidism followed by surgical procedure in patients with thyroid disorders.We analyzed the data acquired from Taiwan's Bureau of National Health Insurance (BNHI) research database from 1998 to 2011 and found 9316 patients with thyroid surgery. Cox regression model was used to calculate the hazard ratio (HR).A count of 314 cases (3.4%) of hypoparathyroidism was identified. The 9 years cumulated incidence of hypoparathyroidism was the highest in patient undergone bilateral total thyroidectomy (13.5%) and the lowest in the patient with unilateral subtotal thyroidectomy (1.2%). However, in the patients who had undergone unilateral subtotal, the risk was the highest in bilateral total (HR: 11.86), followed by radical thyroidectomy with unilateral neck lymph node dissection (HR: 8.56), unilateral total (HR, 4.39), and one side total and another side subtotal (HR: 2.80).The extent of thyroid resection determined the risk of development of hypoparathyroidism. It is suggested that the association of these factors is investigated in future studies.

    Posterior neck pain following thyroidectomy is common because full neck extension is required during the procedure. We evaluated the effect of intra-operative transcutaneous electrical nerve stimulation on postoperative neck pain in patients undergoing total thyroidectomy under general anaesthesia. One hundred patients were randomly assigned to one of two groups; 50 patients received transcutaneous electrical nerve stimulation applied to the trapezius muscle and 50 patients acted as controls. Postoperative posterior neck pain and anterior wound pain were evaluated using an 11-point numerical rating scale at 30 min, 6 h, 24 h and 48 h following surgery. The numerical rating scale for posterior neck pain was significantly lower in the transcutaneous electrical nerve stimulation group compared with the control group at all time points (p < 0.05). There were no significant differences in the numerical rating scale for anterior wound pain at any time point. No adverse effects related to transcutaneous electrical nerve stimulation were observed. We conclude that intra-operative transcutaneous electrical nerve stimulation applied to the trapezius muscle reduced posterior neck pain following thyroidectomy. © 2014 The Association of Anaesthetists of Great Britain and Ireland.

    This study aimed to assess the quality of information available on the World Wide Web for patients undergoing thyroidectomy. The first 50 web-links generated by internet searches using the five most popular search engines and the key word 'thyroidectomy' were evaluated using the Lida website validation instrument (assessing accessibility, usability and reliability) and the Flesch Reading Ease Score. We evaluated 103 of a possible 250 websites. Mean scores (ranges) were: Lida accessibility, 48/63 (27-59); Lida usability, 36/54 (21-50); Lida reliability, 21/51 (4-38); and Flesch Reading Ease, 43.9 (2.6-77.6). The quality of internet health information regarding thyroidectomy is variable. High ranking and popularity are not good indicators of website quality. Overall, none of the websites assessed achieved high Lida scores. In order to prevent the dissemination of inaccurate or commercially motivated information, we recommend independent labelling of medical information available on the World Wide Web.

    Potassium iodide (KI) has traditionally been used to reduce gland vascularity and diminish blood loss in patients undergoing thyroidectomy for Graves disease (GD). Current American Thyroid Association (ATA) guidelines (Recommendation 22) call for its routine administration in GD but avoidance in toxic multinodular goiter (TMNG). A retrospective review (July 2008-May 2012) of perioperative data was performed on 162 patients undergoing total thyroidectomy without preoperative KI and compared to 102 patients with TMNG. Statistical analysis included Student's t test, χ2 test, and multivariate linear regression. Compared to TMNG patients, GD patients had a lower mean age (42.7 vs. 49.6 years, p<0.001) and were less likely to be obese (37 vs. 54%, p=0.047). No patients were provided KI in preparation. GD patients did not differ significantly from TMNG patients with respect to mean estimated blood loss (55.4 vs. 51.5 mL, p=0.773) or mean operative time (131.5 vs. 122.6 min, p=0.084). GD patients had a lower rate of transient hypocalcemia (31 vs. 49%, p=0.004), but the two groups did not statistically differ in rates of prolonged hypocalcemia, temporary recurrent laryngeal nerve (RLN) palsy, prolonged RLN paralysis, or hematoma formation. Although current ATA recommendations for the management of GD call for routine use of KI before thyroidectomy, this large series demonstrates no appreciable detriment to patient outcomes when this goal is not met.

    Post-thyroidectomy parathyroid hormone (PTH) levels have been used to predict hypocalcemia. The goal of this study was to determine whether selective supplementation for post anesthesia care unit (PACU) PTH observation or routine supplementation. Controlled cohort study of thyroidectomy patients, with chart review. Chart review of total or completion thyroidectomy patients in an academic setting. The control group consisted of 124 subjects. The selective supplementation group consisted of 169 subjects with routine PACU PTH testing. The routine supplementation group consisted of 155 subjects with immediate postoperative calcium and vitamin D supplementation. The control group received supplementation for hypocalcemia (calcium routine supplementation group received oral calcium and calcitriol supplementation immediately after surgery. Four separate postoperative day 1 (POD1) outcome measures were evaluated: 1) mean serum calcium; 2) rate of hypocalcemia 10 mg/dL. Mean serum calcium was lower and the rate of hypocalcemia was higher in the control group than the selective PACU PTH group on POD1 (8.2 vs 8.6 mg/dL, P routine supplementation group than in the selective group. However, the rate of hypercalcemia was higher in the routine supplementation group than in the selective group (4.5% vs 0%, P = 0.006). Routine PTH testing and supplementation for patients with hypoparathyroidism reduced the proportion of patients experiencing hypocalcemia. However, supplementation for intraoperative PTH routine supplementation, but with a lower rate of hypercalcemia.

    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.

    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

    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.

    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

    Although there are a limited number of studies showing effects of neck stretching exercises following a thyroidectomy in reducing neck discomfort symptoms, no study has specifically dealt with and examined the effect of neck stretching exercises on neck pain and disability. To analyze the effect of neck stretching exercises, following a total thyroidectomy, on reducing neck pain and disability. A randomized controlled trial was conducted. The participants were randomly assigned either to the stretching exercise group (n = 40) or to the control group (n = 40). The stretching exercise group learned the neck stretching exercises immediately after total thyroidectomy. The effects of the stretching exercises on the participants' neck pain and disability, neck sensitivity, pain with neck movements as well as on wound healing, were evaluated at the end of the first week and at 1 month following surgery. When comparing neck pain and disability scale (NPDS) scores, neck sensitivity and pain with neck movement before thyroidectomy, after 1 week and after 1-month time-points, it was found that patients experienced significantly less pain and disability in the stretching exercise group than the control group (p stretching exercise group were significantly lower than those of the control group. However, there was no significant difference between the groups with regard to the scores at the 1-month evaluation (p > .05). Neck stretching exercises done immediately after a total thyroidectomy reduce short-term neck pain and disability symptoms. © 2016 Sigma Theta Tau International.

    This study aimed to evaluate whether a pre-operative elevated serum alkaline phosphatase level is a potential predictor of post-operative hypocalcaemia after total thyroidectomy. Data was retrospectively collected from the case notes of patients who had undergone total thyroidectomy. Patients were divided into Graves' disease and non-Graves' groups. Pre-operative and post-operative biochemical markers, including serum calcium, alkaline phosphatase and parathyroid hormone levels, were reviewed. A total of 225 patients met the inclusion criteria. Graves' disease was the most common indication (n = 134; 59.5 per cent) for thyroidectomy. Post-operative hypocalcaemia developed in 48 patients (21.3 per cent) and raised pre-operative serum alkaline phosphatase was noted in 94 patients (41.8 per cent). Raised pre-operative serum alkaline phosphatase was significantly associated with post-operative hypocalcaemia, particularly in Graves' disease patients (p alkaline phosphatase measurements help to predict post-thyroidectomy hypocalcaemia, especially in patients who do not develop hypoparathyroidism. Ascertaining the pre-operative serum alkaline phosphatase level in patients undergoing total thyroidectomy may help surgeons to identify at-risk patients.

    Amiodarone can induce severe hyperthyroidism that justifies its withdrawal and the introduction of antithyroid drugs. Continuing amiodarone use, failure to control hyperthyroidism and poor clinical progress may require thyroidectomy. This study aimed to evaluate patients' post-operative development and mid-term outcome after thyroidectomy for amiodarone-associated thyrotoxicosis. Prospective case series. Tertiary care centre. We prospectively collected cases of amiodarone-associated thyrotoxicosis requiring thyroidectomy due to failure of antithyroid treatment, despite amiodarone discontinuation. Post-thyroidectomy complications were compared immediately, 30 days and one year post-operatively, and also for scheduled versus emergency surgery cases. Of 11 total cases, nine scheduled thyroidectomy cases had no morbidity after elective surgery. Two cases required emergency surgery for multiple organ failure and cardiac problems. Immediate post-operative complications (mostly haemodynamic) occurred in both cases (emergency vs routine surgery, p = 0.018). In such cases, pre-operative medical treatment is vital to limit peri- and post-operative complications, but surgery should not be delayed if the haemodynamic status deteriorates. Surgery, with careful anaesthesia, is the cornerstone of the treatment.

    Intraoperative nerve monitoring during thyroidectomy, parathyroidectomy, or related central neck procedures can elucidate actual or potential mechanisms of recurrent laryngeal nerve (RLN) injury, especially visually intact nerves, which were previously unknown to the endocrine surgeon. In this prospective evaluation study, 373 patients underwent 380 consecutive thyroidectomy- or parathyroidectomy-related operations using intraoperative nerve monitoring, with 666 RLNs at risk. The success of visual and functional identification of the RLN, persistent loss of RLN function to nerve stimulation, the mechanism and location of RLN injury, and anatomy of the RLN or technical difficulties that appeared potentially risky for RLN injury were recorded. RLN was identified visually or functionally in 98.2% of nerves at risk. Initial intraoperative injury to the RLN occurred in 25 nerves at risk (3.75%). It was significantly more likely to be a visually intact RLN (n = 22; 3.3%) than a transected RLN (n = 3; 0.45%), p cause of injury resulted from traction to the anterior motor branch of a bifurcated RLN near the ligament of Berry (n = 7; 28%), then paratracheal lymph node dissection (n = 6; 24%), incorporating ligature (n = 4; 16%), and adherent cancer (n = 4; 16%). Fifty nerves at risk (7.5%) were identified as particularly at risk for injury, most notably those with anatomic variants (n = 26; 52%) and large or vascular thyroid lobes (n = 19; 38%). RLN injury during thyroidectomy or parathyroidectomy occurs intraoperatively significantly more often to a visually intact RLN than to a transected nerve. The anterior motor branch of an RLN bifurcating near the ligament of Berry is particularly at risk of traction injury.

    Full Text Available Abstract Background An acute complication of thyroidectomy is fatal hematoma, which can produce an upper airway obstruction needing immediate intubation or tracheostomy. After neck surgery, we usually apply a pressure dressing with a non-woven, adhesive fabric to reduce bleeding and fluid collection at the operative bed. We conducted a prospective, randomized, controlled study to evaluate a pressure vs. a non-pressure dressing after thyroid surgery by monitoring blood and serum in the operative bed. Methods We studied 108 patients who underwent 116 thyroid surgeries at Srinagarind Hospital, Khon Kaen University, between December 2006 and September 2007. The patients were randomized to either the pressure dressing or non-pressure dressing group. Ultrasound of the neck was performed 24 ± 3 hours after surgery. The volume of fluid collection in the operative bed was calculated. All patients were observed for any post-operative respiratory distress, wound complications, tingling sensation or tetany. Results The distributions of age, sex, surgical indications and approaches were similar between the two groups. There was no statistically significant difference in the volume of fluid collection in the operative bed (p = 0.150 and the collected drained content (p = 0.798. The average time a drain was retained was 3 days. One patient in the pressure dressing group suffered cutaneous bruising while one patient in the non-pressure dressing group developed immediate hemorrhage after the skin sutures. Conclusion Pressure dressing after thyroidectomy does not have any significant impact on decreasing fluid collection at the operative bed. The use of pressure dressing after thyroidectomy may not therefore be justified. Trial Registration NCT00400465, ISRCTN52660978

    Objective Recent, more selective use of radioactive iodine (RAI) has led to reevaluation of the clinical importance of achieving complete total thyroidectomy with minimal residual normal thyroid tissue. We utilize the improved localization by post-RAI remnant ablation, single photon emission computerized tomography-computed tomography (SPECT-CT) to define specific anatomic sites of residual RAI-uptake foci after total thyroidectomy for differentiated thyroid cancer (DTC) and to provide a novel classification system relating uptake to thyroid anatomy and preservation of adjacent neural structures. Study Design Retrospective. Method Radioactive iodine-uptake foci in thyroid bed were localized by SPECT/CT imaging at the time of RAI remnant ablation in 141 DTC patients undergoing total thyroidectomy. Results Minimal residual RAI uptake (median 0.32% at 24 hours) in the thyroid bed was detected by diagnostic planar whole body scans in 93% and by posttherapy SPECT/CT imaging in 99% of subjects. Discrete RAI uptake foci were identified on the SPECT/CT imaging at Berry’s ligament (87%), at superior thyroid poles (79%), in paratracheal-lobar regions (67%), in isthmus-region (54%), and in pyramidal lobe (46%). Despite the residual foci, the nonstimulated thyroglobulin (Tg) prior to remnant ablation (with a median thyroid-stimulating hormone of 0.36 m IU/L) was thyroid bed in the majority of patients. These foci can be classified as 1) neural-related and 2) capsule-related. These common residual foci have no relationship to postoperative Tg, suggesting that attempts at radical removal of thyroid tissue in these locations may not be warranted. PMID:25891354

    HYPOTHESIS The cost of robotic thyroidectomy (RT) is significantly higher than that of standard open thyroidectomy (ST). DESIGN A retrospective cost analysis of ST was compared with a projected cost analysis of RT using institution-specific data. SETTING Endocrine surgery division at an academic center. PARTICIPANTS Standard open thyroidectomy data from 2 high-volume endocrine surgeons vs published variables from high-volume RT surgeons. MAIN OUTCOME MEASURES A cost analysis was performed for ST (Current Procedural Technology code 60240). The cost of RT was estimated as operative time plus anesthesia fees plus consumables plus the robotic system (da Vinci Surgical System; Intuitive Surgical, Inc). Institution-specific data were collected for ST, and only those costs that varied between ST and RT were included in the analysis. The mean operative time for ST was based on data from 2 high-volume endocrine surgeons at our institution. The RT operative data were extracted from published series of high-volume RT surgeons. RESULTS The relative costs calculated were $2668 for ST vs $5795 for RT. This represents a 217% increased cost of RT compared with ST. The mean operative times were 113 minutes for ST vs 137 minutes for RT. CONCLUSIONS Technologic advances are paramount in providing the best medical care for patients. This progress must be tempered by a rational, open discussion about the costs of these advancements. Only then can the proposed benefits of a new technology be weighed accurately against the overall societal cost. Surgeons need to be aware of the cost of their technologic choices and the burdens that those place on limited resources.

    Full Text Available Amiodarone is used commonly and effectively in the treatment of arrhythmia; however, it may cause thyrotoxicosis categorized into two types: iodine-induced hyperthyroidism (type 1 amiodarone-induced thyrotoxicosis (AIT and destructive thyroiditis (type 2 AIT. We experienced a case of type 2 AIT, in which high-dose steroid was administered intravenously, and we finally decided to perform total thyroidectomy, resulting in a complete cure of the AIT. Even though steroid had been administered to the patient (maximum 80 mg of prednisolone, the operation was performed safely and no acute adrenal crisis as steroid withdrawal syndrome was found after the operation. Few cases of type 2 AIT that underwent total thyroidectomy with high-dose steroid administration have been reported. The current case suggests that total thyroidectomy should be taken into consideration for patients with AIT who cannot be controlled by medical treatment and even in those under high-dose steroid administration.

    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).

    Robot-assisted transaxillary thyroidectomy (RATT) is widely accepted in Asian countries. However, concerns regarding the balance between its real advantages and safety and cost have been raised by North American authorities. In Europe, assessments have been limited by small numbers since now. The purpose here is to report a large European experience with RATT. A retrospective analysis was conducted of 257 patients who underwent RATT for nodular disease between February 2012 and September 2016. Data collected included patient demographics, diagnosis, ultrasound-estimated mean thyroid volume and nodule size, type of resection, operative time, postoperative pain and morbidity, and the hospital length of stay. Pain was assessed by visual analog scale score 12 h postoperatively (on the first postoperative day, before discharge). Feasibility, effectiveness, and safety were the outcomes of interest. Follow-up of thyroid carcinoma patients was carried out measuring thyroglobulin levels and ultrasound examination (median follow-up 24 months (6-48 months)). First control after 12 months and successively once a year. There were 253 women and 4 men, with a mean age of 37.3 years. Indications included benign disease in 116, papillary carcinoma in 56, and indeterminate nodule in 85. Mean thyroid volume was 16.8 mL, and nodule size was 25.3 mm. A hemithyroidectomy was performed in 138 patients and total thyroidectomy in 118. The mean operative time was 77.5 min for the former and 99.7 min for the latter. One conversion was required. Complications included transient hypoparathyroidism in 7/118 (total thyroidectomy) patients (5.9%), transient vocal fold palsy in 3/257 (1.1%), 1 delayed tracheal injury (0.4%), and 3 postoperative hematoma (1.1%). Mean visual analog scale score was 1.79, and the mean length of stay was 1.6 days for hemithyroidectomy and 1.9 days for total thyroidectomy. RATT is safe and effective and could serve as a viable treatment modality in selected

    Actually, thyroid volume >25 ml, obtained by preoperative ultrasound evaluation, is a very important exclusion criteria for minimally invasive thyroidectomy. So far, among different imaging techniques, two-dimensional ultrasonography has become the more accepted method for the assessment of thyroid volume (US-TV). The aims of this study were: (1) to estimate the preoperative thyroid volume in patients undergoing minimally invasive total thyroidectomy using a mathematical formula and (2) to verify its validity by comparing it with the postsurgical TV (PS-TV). In 53 patients who underwent minimally invasive total thyroidectomy (from January 2003 to December 2007), US-TV, obtained by ellipsoid volume formula, was compared to PS-TV determined by the Archimedes' principle. A mathematical formula able to predict the TV from the US-TV was applied in 34 cases in the last 2 years. Mean US-TV (14.4 +/- 5.9 ml) was significantly lower than mean PS-TV (21.7 +/- 10.3 ml). This underestimation was related to gland multinodularity and/or nodular involvement of the isthmus. A mathematical formula to reduce US-TV underestimation and predict the real TV was developed using a linear model. Mean predicted TV (16.8 +/- 3.7 ml) perfectly matched mean PS-TV, underestimating PS-TV in 19% of cases. We verified the accuracy of this mathematical model in patients' eligibility for minimally invasive total thyroidectomy, and we demonstrated that a predicted TV <25 ml was confirmed post-surgery in 94% of cases. We demonstrated that using a linear model, it is possible to predict from US the PS-TV with high accuracy. In fact, the mean predicted TV perfectly matched the mean PS-TV in all cases. In particular, the percentage of cases in which the predicted TV perfectly matched the PS-TV increases from 23%, estimated by US, to 43%. Moreover, the percentage of TV underestimation was reduced from 77% to 19%, as well as the range of the disagreement from up to 200% to 80%. This study shows that two

    This study sought to probe the feasibility of performing total thyroidectomy in the mouse using a non thyroidal hNIS expressing tumor model. Our thyroidectomy protocol included thorough excision of both lobes and the isthmus. For evaluating the completeness of thyroidectomy, we compared the {sup 99m}Tc pertechnetate scans taken before and after thyroidectomy. The prostate scans taken before and after thyroidectomy. The prostate cancer cell line was subcutaneously inoculated 2 weeks after the thyroidectomy. When the tumor reached 5-10mm in diameter, Ad5/35 E4PSESE1a hNIS was injected intratumorally, and {sup 131I} scans were performed. The radio iodine uptakes of the neck and the tumor were compared with those of the other regions. Total thyroidectomy was performed in 13 mice. Although 38.5% died during or just after thyroidectomy, the others survived in good health for 2 months. Thyroid tissue was completely eliminated using our protocol; the residual uptake of {sup 99m}Tc pertechnetate was minimal in the neck area. The neck/background uptake ratio after thyroidectomy (p<0.05). Non thyroidal tumor models were successfully established in all the surviving mice. Radioiodine accumulation in the tumors was visualized on {sup 131I} scans, and the neck uptakes were minimal. Using our total thyroidectomy protocol, we successfully established a hNIS transfected prostate cancer model with a minimal accumulation of radioiodine in the neck. The relatively high mortality after surgery can be a problem, and this might be reduced by minimizing the surgical stress.

    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.

    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.

    Purpose The aim of this study was to compare a negative pressure drain with a natural drain in order to determine whether a negative pressure drainage tube causes an increase in the drainage volume. Materials and Methods Sixty-two patients who underwent total thyroidectomy for papillary thyroid carcinoma (PTC) were enrolled in the study between March 2010 and August 2010 at Gyeongsang National University Hospital. The patients were prospectively and randomly assigned to two groups, a negative pressure drainage group (n=32) and natural drainage group (n=30). Every 3 hours, the volume of drainage was checked in the two groups until the tube was removed. Results The amount of drainage during the first 24 hours postoperatively was 41.68±3.93 mL in the negative drain group and 25.3±2.68 mL in the natural drain group (pdrainage at postoperative day 3 was not statistically different between the two groups. In addition, the vocal cord palsy and temporary and permanent hypocalcemia were not different between the two groups. Conclusion These results indicate that a negative pressure drain may increase the amount of drainage during the first 24-48 hours postoperatively. Therefore, it is not necessary to place a closed suction drain when only a total thyroidectomy is done. PMID:23225820

    Thyroid cancer account approximately 1.3%-1.5% of cancers all over the body, the attack rate is raising up recently. Most operation is subtotal thyroidectomy at the first time, because thyroid cancer was regarded as thyroid nodule usually account 90.5%. Operation one more time with leftover cancer rate about 41.3%, and with lymphonodi cervicales deadexis about 72.8%. Most patient reluctancy operation again in view of complication with hypoparathyroidism and injure of recurrent nerve. The efficacy of radioiodine ablation can eliminate the minimum cancer which concealed in remained thyroid glandular tissue, and cut down the recurrence rate of thyroid cancer, and destroy metastasis, in favour of long-term follow-up. A great quantity of literature report about 60% with 1.11GBq 131 I and 90% with retreatment with 1.11 GBq 131 I in patients with differentiated thyroid cancer undergoing subtotal thyroidectomy, 131 I treatment can shorten length of stay, and decrease radiation effect, and cut down side effect and economy burden, as far as possible to achieve therapeutic efficacy.

    Full Text Available Background and Objectives. Parathyroid failure is the most common symptom after thyroidectomy. To prevent it, a gland was preserved in situ or an ischemic one was autotransplanted. This study explored the relationship between in situ preservation of the parathyroid gland and gland failure. Methods. Consecutive patients who underwent initial total thyroidectomy were enrolled retrospectively in a prospectively maintained database. Patients were divided into groups by parathyroid gland remaining in situ fraction (PGRIF (PGRIF = number of in situ glands/(total number of identified glands − number of glands in specimen. Patients were graded by tertiles and followed at least one year after surgery. Results. 559 patients were included. PGRIF is significantly inversely associated with transient hypoparathyroidism, protracted hypoparathyroidism, and postoperative hypocalcemia. PGRIF was identified as an independent risk factor for transient hypoparathyroidism, protracted hypoparathyroidism, and postoperative hypocalcemia (OR=0.177, 0.190, and 0.330, resp.. Autotransplantation of parathyroid gland would not affect the calcium level in the long term. Conclusion. In situ preservation of parathyroid gland is crucial for parathyroid function. Less preserved is the independent risk factor for postoperative hypoparathyroidism and hypocalcemia, resulting in a worse function of parathyroid gland in the long term.

    The relationship between the number of parathyroid glands preserved and hypoparathyroidism is not well understood. We sought to determine the number of parathyroid glands that need to be preserved to prevent hypoparathyroidism. We analyzed 454 patients who underwent total thyroidectomy for papillary thyroid carcinoma. We analyzed the frequency of hypoparathyroidism according to the number of parathyroid glands preserved. Incidental parathyroidectomy occurred in 19.8% of the patients; one parathyroid gland in 17.6%, two in 1.5%, and three in 0.7%. Transient hypoparathyroidism was increased when incidental parathyroidectomy occurred (odds ratio 1.83, 95% confidence interval 1.04 to 3.23, P = 0.036) on multivariate regression analysis, but was not influenced by the actual number of parathyroid glands removed. There was no relationship between the number of parathyroid glands preserved and permanent hypoparathyroidism (P = 0.147). Preservation of all parathyroid glands decreases transient hypoparathyroidism compared with when three or fewer glands are preserved, but does not affect permanent hypoparathyroidism. During total thyroidectomy, preserving at least one parathyroid gland with an intact blood supply appears to be sufficient to prevent permanent hypoparathyroidism when autotransplantation is not performed.

    It remains uncertain whether the number of parathyroid glands (PGs) seen during extra-capsular dissection impacts short- and long-term hypoparathyroidism. Our study aimed to address this by analyzing patients who underwent total thyroidectomy for benign disease. Consecutive patients undergoing total thyroidectomy were analyzed. The extra-capsular dissection technique was performed throughout the study period. The number of PGs identified, auto-transplanted and found on excised specimen was recorded prospectively. The number of PGs in situ was equaled to four minus the number of PGs auto-transplanted and PGs found on specimen. Temporary hypoparathyroidism was defined as serum adjusted calcium hypoparathyroidism meant subnormal PTH (6-week oral supplements. Permanent hypoparathyroidism was defined as need for oral supplements for ≥1 year. Five-hundred and sixty-nine patients were eligible for analysis. After adjusting for other significant parameters, greater number of PGs identified was an independent risk factor for temporary (p hypoparathyroidism (p = 0.007). Mean recovery time from protracted hypoparathyroidism for identifying ≤three PGs was significantly shorter than identifying all four PGs (2.8 vs. 7.8 months, p hypoparathyroidism but also shortened recovery from protracted hypoparathyroidism.

    To identify the determinants of operative time for thyroidectomy and quantify the relative influence of preoperative and intra-operative factors. Anticipation of operative time is key to avoid both waste of hospital resources and dissatisfaction of the surgical staff. Having an accurate and anticipated planning would allow a rationalized operating room use and may improve patient flow and staffing level. We conducted a prospective, cross-sectional study between April 2008 and December 2009. The operative time of 3454 patients who underwent thyroidectomy performed by 28 surgeons in five academic hospitals was monitored. We used multilevel linear regression to model determinants of operative time while accounting for the interplay of characteristics specific to surgeons, patients, and surgical procedures. The relative impact of each variable on operative time was estimated. Overall, 86% (99% CI 83 to 89) of operative time variation was related to preoperative variables. Surgeon characteristics accounted for 32% (99% CI 29 to 35) of variation, center location for 29% (99% CI 25 to 33), and surgical procedure or patient variables for 24% (99% CI 20 to 27). Operative time was significantly lower among experienced surgeons having practiced from 5-19 years (-21.8 min, Pcost management.

    Full Text Available A 51 year old man presented with sepsis in the setting of thioamide-induced agranulocytosis. Empiric broad-spectrum antibiotics was followed by directed narrow-spectrum antibiotics, and his neutrophil count recovered with support from granulocyte-colony stimulating factor (G-CSF analogue transfusions. After a brief period of multi-modal therapy for nine days including potassium iodide (Lugol’s iodine, cholestyramine, propanolol and lithium to temper his persisting hyperthyroidism, a total thyroidectomy was performed while thyroid hormone levels remained at thyrotoxic levels. Postoperative recovery was uncomplicated and he was discharged home on thyroxine. There is limited available evidence to guide treatment in this unique cohort of patients who require prompt management to avert impending clinical deterioration. This case report summarises the successful emergent control of thyrotoxicosis in the setting of thioamide-induced agranulocytosis complicated by sepsis, and demonstrates the safe use of multi-modal pharmacological therapies in preparation for total thyroidectomy.

    Full Text Available Thyroidal pain is usually due to subacute thyroiditis (SAT. In more severe forms prednisone doses up to 40 mg daily for 2-3 weeks are recommended. Recurrences occur rarely and restoration of steroid treatment cures the disease. Rarely, patients with Hashimoto’s thyroiditis (HT have thyroidal pain (painful HT, PHT. Differently from SAT, occasional PHT patients showed no benefit from medical treatment so that thyroidectomy was necessary. We report three patients who did not show clinical response to prolonged high dose prednisone treatment: a 50-year-old man, a 35-year-old woman, and a 33-year-old woman. Thyroidectomy was necessary, respectively, after nine-month treatment with 50 mg daily, two-month treatment with 75 mg daily, and one-month treatment with 50 mg daily. The two women were typical cases of PHT. Conversely, in the first patient, thyroid histology showed features of granulomatous thyroiditis, typical of SAT, without fibrosis or lymphocytic infiltration, typical of HT/PHT, coupled to undetectable serum anti-thyroid antibodies. Our data (1 suggest that not only PHT but also SAT may show resistance to steroid treatment and (2 confirm a previous observation in a single PHT patient that increasing prednisone doses above conventional maximal dosages may not be useful in these patients.

    This study is the first to evaluate scar satisfaction and body image in thyroidectomy patients using validated assessment tools. A total of 123 thyroidectomy patients were recruited over 8 months. Both patients and clinicians completed assessment tools that included: the Manchester Scar Scale (to measure scar perception), Dysmorphic Concern Questionnaire (to assess body image), Body Dysmorphic Concern Questionnaire (to screen for body dysmorphic disorder) and EQ-5D (to measure life quality). A separate image panel comprising experts and non-experts assessed 15 scar photographs. The results were analysed using non-parametric descriptive statistics. Poor body image was associated with poor scar perception (ρ = 0.178, p = 0.05). Poor life quality correlated with poor scar perception (ρ = -0.292, p = 0.001). Scar length did not affect scar perception. Prevalence of body dysmorphic disorder among patients was found to be 8.94 per cent, which is higher than general population rates. Negative body image and life quality impact negatively upon scar perception.

    Rhabdomyolysis is characterized by skeletal muscle breakdown. It is a potential cause of serious electrolyte and metabolic disturbances, acute kidney insufficiency, and death. Recently, rhabdomyolysis has been increasingly recognized following certain surgical procedures. We discuss the case of a morbidly obese 51-year-old woman who developed postoperative rhabdomyolysis of the lumbar muscles following a prolonged thyroidectomy for a large goiter. We discuss how her morbid obesity, the supine surgical position, the duration of surgery (including prolonged exposure to anesthetic agents), and postoperative immobility contributed to the development of rhabdomyolysis. Immediately after surgery, the patient developed hypocalcemia, which was likely due to rhabdomyolysis since her serum parathyroid hormone level was normal. Later, however, persistent hypocalcemia despite resolution of the rhabdomyolysis raised a suspicion of iatrogenic hypoparathyroidism, which was confirmed by a suppressed parathyroid hormone level several days after surgery. In post-thyroidectomy patients with risk factors for rhabdomyolysis, maintaining a high degree of clinical suspicion and measuring serum creatine kinase and parathyroid hormone levels can allow for an accurate interpretation of hypocalcemia.

    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.

    Because the fluorescent light intensity on an indocyanine green fluorescence angiography reflects the blood perfusion within a focused area, the fluorescent light intensity in the remaining in situ parathyroid glands may predict postoperative hypocalcemia risk after total thyroidectomy. Seventy patients underwent intraoperative indocyanine green fluorescence angiography after total thyroidectomy. Any parathyroid glands with a vascular pedicle was left in situ while any parathyroid glands without pedicle or inadvertently removed was autotransplanted. After total thyroidectomy, an intravenous 2.5 mg indocyanine green fluorescence angiography was given and real-time fluorescent images of the thyroid bed were recorded using the SPY imaging system (Novadaq, Ontario, Canada). The fluorescent light intensity of each indocyanine green fluorescence angiography as well as the average and greatest fluorescent light intensity in each patient were calculated. Postoperative hypocalcemia was defined as adjusted calcium 150% developed postoperative hypocalcemia while 9 (81.8%) patients with a greatest fluorescent light intensity ≤150% did. Similarly, no patients with an average fluorescent light intensity >109% developed PH while 9 (30%) with an average fluorescent light intensity ≤109% did. The greatest fluorescent light intensity was more predictive than day-0 postoperative hypocalcemia (P = .027) and % PTH drop day-0 to 1 (P parathyroid glands function and predicting postoperative hypocalcemia risk after total thyroidectomy.

Twenty female Wistar rats were randomly divided into two groups: 1 thyroidectomy caused hypothyroidism, in which the thyroid gland had been removed and the parathyroid reimplanted; and 2 false thyroidectomy. The thyroidectomy was made on rats anesthetized with ketamine-xylazine. The rats were mated and one day after giving birth, eight pups were assigned to each group randomly and they were distributed into two groups: a hypothyroid group containing male pups of a hypothyroid mother with a hypothyroid wet nurse; and a euthyroid group of male pups of a euthyroid mother with a euthyroid wet nurse. We analyzed the behavioral test at a prepubertal age. The neonatal and perinatal hypothyroidism caused by the mother’s thyroidectomy caused a decrease in body weight and length. We found that the neonatal and perinatal hypothyroidism enhanced the total exploratory activity without affecting social contact and the time spent in the open and closed arms in an elevated plus-maze. The hypothyroidism caused immobility without altering the lower climbing duration in the swimming test. This study shows a novel model to cause neonatal and perinatal hypothyroidism without using pharmacological drugs. We demonstrated that hypothyroid animals had a reduction in body weight and length, a retardation of neurodevelopment, and they had depressive-like behavior.Keywords: perinatal hypothyroidism, thyroidectomy, thyroid hormone, behavior, metabolism

    Amiodarone plays a pivotal role in the treatment of ventricular and supraventricular arrhythmias. However, amiodarone-induced hyperthyroidism (AIH) is one of the most feared complications, which necessitates interdisciplinary treatment and careful balancing of the risks of conservative treatment against those of total thyroidectomy. In this article we discuss the pharmacological aspects of amiodarone and its diverse effects on the thyroid. Furthermore, we present diagnostic and therapeutic strategies and report our positive experiences with total thyroidectomy in patients with AIH. Particularly in patients for whom continuation of amiodarone treatment is compulsory, a well-timed total thyroidectomy is a reliable therapeutic option, with minimal complication rates and immediate amelioration of symptoms.

    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.

    Thyroid carcinoma is usually indolent with good prognosis, as compared to other malignancy. Distant metastases from thyroid cancer are rare and usually manifest as multiple lesions especially in lungs, bones and lymph nodes, in advanced stages of the disease. Metastasis to the breast from thyroid carcinoma is extremely rare, with about 16 cases reported in the English literature. Herein, we reported a case of metastatic poorly differentiated thyroid carcinoma, which presented as 2 breast masses in a 72-year-old woman, 6 years after total thyroidectomy for papillary thyroid carcinoma. Although the computed tomography (CT) and ultrasonography (USG) image findings are nonspecific oval mass with circumscribed or partially indistinct margin, metastases from thyroid cancer should be included in the differential diagnosis when recurrence of thyroid carcinoma is suspected. Also, fusion images of CT and USG are helpful to the radiologists in localizing the targeted lesion and conducting accurate USG-guided biopsy.

    The aim of the present study was to identify a fast, efficient and low-cost method to diagnose hypoparathyroidism after total thyroidectomy. One hundred and forty medical records, which contained patients' clinical and laboratory data, were retrospectively analyzed. Patient parathyroid hormone values, which were obtained immediately following operation, were compared with their ionized calcium levels the morning after surgery. This comparison was used to examine the correlation between the two variables in predicting hypoparathyroidism because measuring calcium levels is low-cost and more available in the hospitals compared to measuring parathormone (PTH) levels. There was a positive and statistically significant correlation between PTH and ionized calcium values (Pearson correlation coefficient, r = 0.456; p hypoparathyroidism, and a PTH hypoparathyroidism. In conclusion, we demonstrated that patients who had high ionized calcium levels on the first postoperative day also had high PTH levels immediately following operation and, therefore, they had lower rates of hypoparathyroidism.

    We report the case of a female patient in whom gluten-induced entheropathy was revealed at the age of 71 yr by resistance to treatment with levothyroxine (L-T4), calcium carbonate and alfacalcidol. Hypothyroidism and hypoparathyroidism were the consequence of a total thyroidectomy performed at the age of 65 yr for a large multinodular goiter. Six months after thyroid ablation the patient started to complain of abdominal pain, diarrhea and weight loss. Following, anemia and osteopenia were documented. A progressive increase of replacement therapy for hypothyroidism and hypoparathyroidism was necessary. The clinical presentation suggested a malabsorption syndrome: celiac disease (CD) was diagnosed by serological markers and duodenal biopsy. Following gluten-free diet a normalization of clinical and serological findings was observed, bone mass density improved and a reduction of L-T4, calcium and vitamin D requirements was observed.

    The role of thyroid hormones in the maintenance of juvenile refractoriness was studied in the red-legged partridge hybrid, Alectoris graeca chukar. Juvenile partridges, maintained on long (20L:4D) daylengths from hatch, were radiothyroidectomized at 6 1/2 weeks of age, and after 2 weeks were either held on long days or transferred to short (8L:16D) daylengths. Short-day thyroidectomized birds showed no evidence of gonadal growth 18 weeks after thyroidectomy, and neither did euthyroid controls on either short or long daylengths. Thyroidectomized birds held on long daylengths did show significant gonadal growth at this point. Further treatment with low levels of thyroxine (10 micrograms/bird) led to even greater testicular development in long-day thyroidectomized birds, but had no effect on the gonads of short-day thyroidectomized or euthyroid birds

    It remains uncertain whether a parathyroid gland (PG) that appears darkened or severely bruised but still has an attached vascular pedicle should be left in situ or taken out and auto-transplanted following total thyroidectomy. Our study aimed to examine the impact of discolored PGs (DPGs) on short- and long-term hypoparathyroidism. One hundred and three patients who underwent total thyroidectomy with 4 clearly identified PGs were analyzed. Location (superior/inferior) and color of each PG were recorded. Patients without DPG were grouped into I while those with 1-2 DPGs and ≥3 DPGs were grouped into II and III, respectively. Transient hypoparathyroidism meant adjusted Ca hypoparathyroidism meant a subnormal PTH at 4-6 weeks and/or supplements >6 weeks. Permanent hypoparathyroidism meant supplements ≥1 year. Relative to I, group III had greater adjusted Ca drop at postoperative 1-h (p = 0.012), 24-h (p hypoparathyroidism. However, permanent hypoparathyroidism rate was higher than in group I than II (p = 0.019). Eight patients (25.8 %) in group I had undetectable day-1 PTH, while none in group III had undetectable day-1 PTH. Graves' disease/toxic goiter (OR 15.166, 95 % CI 2.594-88.661, p = 0.003) and excised gland weight (OR 1.028, 95 % CI 1.010-1.046, p = 0.003) were independent factors of ≥3 DPGs. PG discoloration is associated with transient hypoparathyroidism while normal colored PG with seemingly adequate blood supply does not always imply functionally normal gland. These findings highlights the need for a real-time intraoperative method to assess PG viability.

The occurrence of hypocalcemia is mainly attributed to hypoparathyroidism when parathyroid glands are devascularized, injured, or dissected during the surgery. The aim of this study was to analyze the risk factors for hypocalcemia and hypoparathyroidism following thyroidectomy. Patients and methods: A total of 278 patients who underwent thyroid surgery were analyzed retrospectively. Univariate analysis and multivariable logistic regression were performed to discover the risk factors for hypocalcemia and hypoparathyroidism.Results: Postoperative hypocalcemia occurred in 76 (27.3% patients and hypoparathyroidism occurred in 42 (15.1% patients. Seven factors were significantly related to the presence of postoperative hypocalcemia, namely, age (P=0.049, gender (P=0.015, lateral lymph node dissection (P=0.017, operation type (P<0.001, preoperative parathyroid hormone (PTH level (P=0.035, operation time (P=0.001, and applying carbon nanoparticles (CNs; P=0.007. Our result revealed that gender (P=0.014, lateral lymph node dissection (P=0.038, operation type (P<0.001, operative time (P<0.001, and applying CNs (P=0.001 had a significant correlation with postoperative hypoparathyroidism.Conclusion: These findings were crucial for guiding surgeons to prevent the occurrence of hypocalcemia and hypoparathyroidism.

    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.

    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.

    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.

    1998-01-01

    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.

    Full Text Available Thyroglobulin (Tg is an important modality for monitoring patients with thyroid cancers, especially after thyroidectomy followed by radioiodine (RAI. It is also used as a marker for burden of thyroid tissue whether malignant or benign. Although there have been several reports of rising serum Tg transiently after thyroid biopsy in intact glands and following palpation or trauma, there are no reports in the literature of elevation in Tg after biopsy of suspicious lesions in thyroidectomized patients. In this paper we report a fascinating case of a considerable and initially worrying, although ultimately transient, rise in Tg in a patient 2 years after total thyroidectomy and RAI ablation after fine needle aspiration (FNA of a suspicious thyroid bed nodule that was proven positive.

    Full Text Available BackgroundOpen thyroidectomy is conventionally performed at the anterior side of neck, which is a body part with a comparatively great degree of open exposure; due to this, postoperative scarring may cause distress in patients. We aimed to compare the effects of ablative and nonablative fractional laser treatments on thyroidectomy scars. We examined medical records in a retrospective manner and analyzed scars based on their digital images by using the modified Manchester Scar Scale (mMSS.MethodsBetween February 2012 and May 2013, 55 patients with thyroidectomy scars were treated with ablative (34 patients or nonablative (21 patients fractional laser. Each patient underwent 4 laser treatment sessions in 3–4 week intervals, 1–2 months postoperatively. Scar improvement was assessed using patient images and the mMSS scale.ResultsThe mean decrease in scar score was 3.91 and 3.47 in the ablative and nonablative groups, respectively; the reduction between 2 groups did not exhibit any significant difference (P=0.16. We used the scale once again to individually evaluate scar attributes. The nonablative group accounted for a considerably higher color score value (P=0.03; the ablative group accounted for a considerably higher contour score value (P<0.01. Patient satisfaction was high and no complications occurred.ConclusionsBoth types of fractional laser treatments can be used successfully for thyroidectomy scar treatment with minimal complications; however, results indicate that higher effectiveness may be obtained from the use of ablative and nonablative lasers for hypertrophic scars and early erythematous scars, respectively. Therefore, the appropriate laser for scar treatment should be selected according to its specific characteristics.

    We often recommend total thyroidectomy for patients with Graves' disease who wish to have a child in the near future in order to prevent fetal or neonatal hyperthyroidism, especially if the patients' serum thyrotropin receptor antibody (TRAb) values are high. The aim of this study was to analyze changes in serum TRAb values using a quantitative third-generation assay after total thyroidectomy and the half-lives of serum TRAb values to estimate the postoperative time needed to achieve the safe TRAb value for mothers. We retrospectively examined the records of 45 Graves' disease patients who underwent a total thyroidectomy and had high serum TRAb values. We also evaluated factors that prolonged the postoperative reduction of serum TRAb values. The serum TRAb values decreased rapidly in most of the patients, especially within the early postoperative (3-month) period. The presence of Graves' ophthalmopathy (GO) (p=0.001), smoking (p=0.004), and serum thyroglobulin values > 0.5 ng/mL at postoperative 12 months (p=0.039) were significantly associated with prolonged half-lives of the serum TRAb values. The median TRAb value half-life was 93.5 days in the patients without GO or smoking, 162.5 days in the patients with GO or smoking, and 357.4 days in the patients with both GO and smoking. Our findings indicate that using the half-life of patients' serum TRAb values determined by this third-generation assay would be effective to evaluate the reduction of serum TRAb values after total thyroidectomy and to estimate the postoperative time needed to achieve the maternal safe value.

    Minimally invasive video-assisted thyroidectomy (MIVAT) is a surgical technique that has showed increasingly good results, particularly in endocrine surgery centers. The aim of this prospective, non-randomized study was to evaluate feasibility, advantages and critical aspects of MIVAT in a general surgery unit. Two hundred twenty-four patients underwent total thyroidectomy for benign thyroid disease from May, 2008 to April, 2011. They were divided into two groups: one underwent conventional thyroidectomy (CT), and the other underwent MIVAT. The inclusion criteria were thyroid volume ≤35 mL and main nodule size ≤35 mm. For each patient, socio-demographic variables, hospitalization data and outcome measures (complication rate, operating time, post-operative pain, observer and patient scar assessment scale [OSAS and PSAS, respectively]) were collected. Multivariate regression analyses were done to assess the principal covariates affecting these outcome measures. There were 125 MIVATs and 99 CTs performed. The two groups were characterized by difference in age (38.4 vs. 50.9 years) and thyroid volume (18.6 vs. 23.3 mL). OSAS/PSAS scores were statistically significant in the MIVAT group (Pcosmetic results. It can be performed in younger patients and in all cases in which there is a clear indication for the procedure. Its advantages were confirmed in a general surgery unit where correct indications were followed.

    This study aimed to assess the accuracy of ultrasound (US) diagnosis for retrojugular lymphadenopathy in patients who had undergone total thyroidectomy, due to thyroid malignancy. During a follow up period after total thyroidectomy, due to known thyroid malignancy, 41 patients underwent US diagnosis and US guided fine needle aspiration for retrojugular lymphadenopathy. Each lymphadenopathy was prospectively classified by a single radiologist into 1 of 3 diagnostic categories: 'benign', 'indeterminate for malignancy', and 'malignant'. Based on the cytohistopathology result, thyroglobulin tittering, and sonographic follow up, the adequacy of US diagnosis for retrojugular lymphadenopathy was assessed. Of the 41 retrojugular lymphadenopathies, malignant (n = 25) and benign (n = 16) lymphadenopathy were finally confirmed. Excluding 15 lymph nodes with indeterminate US diagnosis, the sensitivity, specificity, positive and negative predictive values, accuracy, and false positive and negative rates of US diagnosis were 100%, 66.7%, 95.8%, 100%, 96.2%, 0%, and 10%, respectively. There was no significant difference in the incidence of retrojugular lymphadenopathy, according to age, sex, and location (p > 0.05). In the patient with a history of total thyroidectomy, due to thyroid malignancy, US diagnosis for retrojugular lymphadenopathy showed a high accuracy.

    To elucidate the necessity of Lugol's iodine in preoperative preparation of patients undergoing thyroidectomy. Hundred and five euthyroid patients who underwent surgery without preoperative preparation of patients with Lugol's iodine were enrolled in this retrospective study conducted during the period May 2009 to August 2013 in Teaching Hospital. Indication of surgery was ranging from suspected malignancy to cosmetic reasons and compressive features like dysphagia , dyspnoea and hoarseness of voice. All patients were operated by the same surgeon where in hemi, total and subtotal thyroidectomies were performed without any usage of Lugol's iodine preoperatively. During the postoperative period the following events occurred, five patients (4.7%) had incurred recurrent laryngeal nerve palsy (RLNP) which was confirmed with postoperative indirect laryngoscopic examination and two patients (1.9%) with hypocalcemia (serum calcium less than 8mg/dl) which was managed conservatively and effectively. Among these five patients, three patients had (Right RLNP) and two patients had (Left RLNP) palsies. Of these four RLNP (3.8%) were temporary which improved with conservative management within 3weeks-6months duration and one (0.9%) was a permanent Rt RLNP with no improvement even after six months. Hence, we conclude that it is not of much importance to use Lugol's iodine preoperatively in patients undergoing thyroidectomy. There does not appear any convincing evidence of advantages of preoperative preparation of patients with lugol's iodine in euthyroid state undergoing surgery.

    The optimum size of endotracheal tube (ETT) for general anesthesia remains unresolved. Choice of ETT size may be of particular relevance to thyroid surgery because of the increased risk of laryngeal trauma and concerns regarding postoperative vocal outcomes. To test our hypothesis that intubation with a smaller ETT would lead to reduced postoperative vocal impairment and associated reduced laryngoscopic evidence of laryngeal trauma compared with intubation with a standard-size ETT. This double-blind randomized clinical trial studied patients 18 years and older undergoing elective thyroidectomy at an academic teaching hospital from October 15, 2012, through June 13, 2013. Patients were randomized to group 1 (standard-size ETT, 8.0 mm for men and 7.5 mm for women; n = 24) or group 2 (small ETT, 7.0 mm for men and 6.5 mm for women; n = 25). Patients were assessed preoperatively and at 24 hours and 3 weeks postoperatively. Fiberoptic videolaryngoscopy with modified scoring system, voice assessment using the GRBAS (grade, roughness, breathiness, asthenia, strain) rating scale, vocal self-assessment using the 30-item Voice Handicap Index, and subjective pain score. At 24 hours, no significant differences were found between patients in groups 1 and 2 in change in GRBAS scores, change in laryngoscopic score (1.71 vs 1.76, P = .90), or postoperative pain score (3.3 vs 3.2, P = .91). At 3 weeks, no significant differences were found in changes in the 30-item Voice Handicap Index score (-2.2 vs -1.3, P = .74), GRBAS scores, or laryngoscopic score (0.25 vs 0.16, P = .67). We did not find evidence that smaller ETT size for thyroidectomy has any significant effect on postoperative vocal outcomes, incidence of laryngeal trauma as assessed by laryngoscopy, or pain scores. However, because of the small sample size, our study may have been underpowered to detect small differences. clinicaltrials.gov Identifier: NCT02136459.

    Abstract The best method of preventing hypoparathyroidism after thyroidectomy is to keep parathyroid glands in situ. However, hypoparathyroidism still regularly occurs with the existing parathyroid classification system, and the incidence of permanent hypoparathyroidism has not been reduced. We created a novel system for classifying parathyroid glands that can guide parathyroid preservation in thyroidectomy. We prospectively observed parathyroid glands using the new system in 218 neck surgeries, compared with 132 under the traditional system from January 2014 to September 2015 at a single clinic center. Briefly, we classified parathyroid glands as follows: Type A, no dependency on the thyroid; B1, partial blood supply from the thyroid but retains adequate blood supply after removal of the thyroid; B2, partial blood supply from the thyroid and becomes devascularized after the removal of the thyroid; B3, blood supply mostly from the thyroid; and C, blood supply completely dependent on the thyroid. The classifications were used to decide between in situ preservation or auto-transplantation. The most common type of parathyroid gland was type B1 (53.77%), followed by type A (20.89%), which are the perfect categories for in situ preservation. Type B2 (17.52%) and type B3 (1.21%) have a chance to be kept in situ. For type C (6.61%), in situ preservation is impossible. When in-situ preservation is ruled out, parathyroid auto-transplantation is an alternative, with partial or total gland tissue, depending on the classification and the surgeon's discretion. Among the patients who were classified under the new system, 43.6% presented with transient hypoparathyroidism (symptoms lasting ≤6 months) after surgery, versus 42.4% in the old system, which was not a significant difference. However, permanent hypothyroidism (symptoms lasting >6 months) was not detected in the applied group, but in 3.0% of patients in the nonapplied group (P = 0.01). Our novel functional

    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.

    Full Text Available [b][/b]Introduction. Recently, intraoperative neurophysiological neuromonitoring (IONM of recurrent laryngeal nerves (RLN has been evolving quickly. This evolution touched many aspects of the technique, leading to continuous stimulation of the RLN with real time analysis of the electrical signal. Objective. The aim of the study was to estimate the value of continuous intraoperative neuromonitoring (CIONM as the only technique for intraoperative neuromonitoring in thyroidectomy performed because of benign goitre. Material and methods. The study comprised 80 women qualified for thyroidectomy due to nodular goitre. The patients were divided into 4 groups depending on the technique used for RLN integrity verification: group 1 – thyroidectomy with CIONM; group 2 – thyroidectomy with direct, intermittent stimulation of RLN and vagus nerve (NX; group 3 – both CIONM and intermittent stimulation of RLN and NX; group 4 – thyroidectomy without any IONM. Results. Mean operation time did not differ significantly among the groups with IONM, but was significantly longer in comparison to group 4, as well as the operation’s cost. In the analysed groups there was no significant difference in complication ratio. Conclusion. CIONM with RLN visualization in thyroidectomy performed because of benign goitre is as safe as other methods of IONM and gives a continuous confirmation of the electrical integrity of the loop NX-RLN-vocal folds during almost the entire procedure. There is a clinical need for the development of external stimulation of NX (transdermal or trancranial, particularly for minimally invasive techniques in which access to NX is limited (i.e. transoral thyroidectomy.

  9. Takotsubo cardiomyopathy precipitated by negative pressure pulmonary oedema following total thyroidectomy

    Full Text Available 'Takotsubo cardiomyopathy (TCM' or 'stress cardiomyopathy' is a reversible cardiomyopathy that is precipitated by intense emotional or physical stress. This syndrome is characterised by symptoms mimicking acute coronary syndrome with transient systolic dysfunction associated with regional wall motion abnormalities, which extend beyond a single coronary vascular bed in the absence of obstructive coronary vascular disease. The presentation of TCM and myocardial infarction is similar with sudden onset of chest pain, breathlessness as well as abnormalities in both the electrocardiogram and cardiac enzymes. It is difficult to differentiate between the two until cardiac catheterisation establishes the diagnosis. We report a case of TCM in a post-menopausal female, precipitated by negative pressure pulmonary oedema following total thyroidectomy in whom timely cardiac catheterisation established the diagnosis and influenced the management. Heightened awareness of this unique cardiomyopathy is essential to have a high index of suspicion in at-risk population for the prompt diagnosis of stress-related cardiomyopathy syndromes occurring in the perioperative period.

    Current postoperative thyroid replacement dosing is weight based, with adjustments made after thyroid-stimulating hormone values. This method can lead to considerable delays in achieving euthyroidism and often fails to accurately dose over- and underweight patients. Our aim was to develop an accurate dosing method that uses patient body mass index (BMI) data. A retrospective review of a prospectively collected thyroid database was performed. We selected adult patients undergoing thyroidectomy, with benign pathology, who achieved euthyroidism on thyroid hormone supplementation. Body mass index and euthyroid dose were plotted and regression was used to fit curves to the data. Statistical analysis was performed using STATA 10.1 software (Stata Corp). One hundred twenty-two patients met inclusion criteria. At initial follow-up, only 39 patients were euthyroid (32%). Fifty-three percent of patients with BMI >30 kg/m(2) were overdosed, and 46% of patients with BMI regression equation was derived for calculating initial levothyroxine dose (μg/kg/d = -0.018 × BMI + 2.13 [F statistic = 52.7, root mean square error of 0.24]). The current standard of weight-based thyroid replacement fails to appropriately dose underweight and overweight patients. Body mass index can be used to more accurately dose thyroid hormone using a simple formula. Copyright © 2013 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

    The purpose of this study is to investigate whether or not radio-guided surgery has any beneficial effects on completion thyroidectomy (CT) and the associated complication rates. Twenty seven patients were scheduled for CT, for thyroid carcinoma, from December 2004 to June 2005, and were included in the study. All the patients had initial thyroid surgery in other centers and been referred to our clinic for CT. Operation findings and the effectiveness of 99m Tc radio-guided CT were analyzed. The intraoperative mean ratio of thyroid activity to background activity counted with a gamma probe was 1.3 ± 0.3. Average operation timing was 74 ± 9 minutes. Postoperatively, no residual tissue was detected in any of the patients with ultrasonography and thyroid scintigraphy. In the first postoperative month, serum TSH level was 61 ± 16.4 mlU/L, when preoperatively it was 7.3 ± 3.1 mlU/L (P < 0.001). In the postoperative period, one patient experienced temporary hypoparathyroidism (3.9%). Permanent hypoparathyroidism or recurrent laryngeal nerve damage was not detected in any patient. Tc-99 radio-guided CT is a reliable surgical method, which provides the detection and removal of residual thyroid tissues with minimal complications. (author)

  12. Risk of Vocal Palsy After Thyroidectomy with Identification of the Recurrent Laryngeal Nerve

    2004-09-01

    Full Text Available The purpose of this study was to assess the risk of vocal palsy after thyroidectomy with identification of recurrent laryngeal nerve (RLN during surgery. In all, 521 patients treated by the same surgeon were enrolled in this study. Temporary and permanent vocal palsy rates were analyzed for patient groups classified according to surgery for primary benign thyroid disease, thyroid cancer, Graves' disease, and reoperation. Measurement of the vocal palsy rate was based on the number of nerves at risk. Twentysix intentionally sacrificed RLNs were excluded from analysis. Forty patients developed postoperative unilateral vocal palsy. Complete recovery of vocal palsy was documented for 35 of the 37 patients (94.6% whose RLN integrity had been ensured intraoperatively. Recovery from temporary vocal palsy ranged from 3 days to 4 months (mean, 30.7 days. The overall incidences of temporary and permanent vocal palsy were 5.1% and 0.9%, respectively. The rates of temporary/permanent vocal palsy in groups classified according to underlying disease were 4.0%/0.2% for benign thyroid disease, 2.0%/0.7% for thyroid cancer, 12.0%/1.1% for Graves' disease, and 10.8%/8.1% for reoperation. Surgery for thyroid cancer, Graves' disease, and recurrent goiter were associated with significantly higher vocal palsy rates. Most patients without documented nerve damage during the operation recovered from postoperative vocal palsy. Total lobectomy with routine RLN identification is recommended as a basic procedure in thyroid surgery.

    In esthetic surgery, understanding the factors that influence patient satisfaction is important for successful practice. We hypothesize that the factors that influence patient satisfaction include not only aesthetic and functional outcomes, but also personal factors such as the level of familiarity with factors affecting wound healing and expectations regarding aesthetic outcome. One hundred patients who underwent esthetic closure after thyroidectomy were included in this study. In order to evaluate the individual characteristics of the patients, a preoperative survey was administered to the patients. We estimated the patient satisfaction six months postoperatively and assessed the aesthetic and functional outcomes using the Patient and Observer Scar Assessment Scale. According to the results of correlation analysis, level of familiarity with wound healing factors had a positive correlation with satisfaction. High expectations, pain, itching, and high observer scale score had negative correlations with satisfaction. The factors that were correlated with satisfaction were included in the multiple regression analysis. Level of familiarity with wound healing factors was found to have a positive relationship with satisfaction, while itching and observer scale were found to have a negative relationship with satisfaction. After excluding 10 patients who had hypertrophic scars, only level of familiarity with wound healing factors and expectations affected satisfaction. The level of familiarity with factors affecting wound healing and expectations were found to independently affect satisfaction. Improving patients' level of familiarity with wound healing factors and reducing their expectations by providing suitable preoperative education has the potential to improve patient satisfaction.

    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

    The integral search for improved living conditions for those patients with gastric cancer who have not received curative surgical treatment continues to challenge the knowledge, dexterity and ethical foundations of medical teams. The justification for palliative treatment must be based on a thorough consideration of the available options and the particular situation in each case. This article reviews endoscopic therapy with auto expandable prosthetics for palliative treatment of gastric cancer, as well as the scientific evidence that supports its use and the factors that determine its indication.

    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.

  17. Long-Term Results after Treatment of Very Low-, Low-, and High-Risk Thyroid Cancers in a Combined Setting of Thyroidectomy and Radio Ablation Therapy in Euthyroidism

    2013-01-01

    Full Text Available Introduction. Differentiated thyroid cancer treatment usually consists of thyroidectomy and radio ablation in hypothyroidism 4-6 weeks after surgery. Replacing hypothyroidism by recombinant human thyroid stimulating hormone can facilitate radio ablation in euthyroidism within one week after surgery. The outcome of this approach was investigated. Methods. This is a prospective randomized trial to compare thyroidectomy and radio ablation within a few days after preconditioning with recombinant human thyroid stimulating hormone versus thyroidectomy and radio ablation separated by four weeks of L-T4 withdrawal. Tumors were graded into very low-, low- , or high-risk tumors. Recurrence-free survival was confirmed at follow-up controls by neck ultrasound and serum thyroglobulin. Suspected tumor recurrence was treated by additional radio ablation or surgery. Quality-of-life questionnaires with additional evaluation of job performance and sick-leave time were used in all patients. Results. Radio ablation in euthyroidism in quick succession after thyroidectomy did not lead to higher tumor recurrence rates of differentiated thyroid cancers in any risk category and was significantly advantageous with respect to quality-of-life (P<0.001, sick-leave time (P<0.001, and job performance (P=0.002. Conclusion. Recombinant human thyroid stimulating hormone can be used safely and with good efficacy to allow radio ablation under sustained euthyroidism within one week after thyroidectomy.

  18. Endoscopic management of bleeding peptic ulcers

    2001-01-01

    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)

    Friedel, David; Modayil, Rani; Iqbal, Shahzad; Grendell, James H.

    2013-01-01

    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

    Full Text Available Abstract Introduction A non-recurrent variant of the inferior laryngeal nerve has been seldom reported. These reports are mostly based on cadaveric dissection studies or large chart review studies in which the emphasis is placed on the determination of the frequency of the variation, and not on the clinical appearance of this variant. We graphically describe the intraoperative identification of a non-recurrent inferior laryngeal nerve. Case Presentation A 44-year old Caucasian man was referred to the Head and Neck Surgery Outpatient Clinic with the diagnosis of a nodular mass in his left thyroid lobe that had been growing for one year. A fine needle aspiration puncture was compatible with thyroid papillary cancer. It was decided that the patient should undergo total thyroidectomy. During surgery, a non-recurrent right inferior laryngeal nerve was noted. This nerve emanated from the right vagus nerve, entering the larynx 3 cm after its origin. The nerve did not show a recurrent course. The nerve on the left side had a normal configuration. The surgery and post-operative period were uneventful, and the patient had no change in his voice. Conclusion This paper allows those interested to become acquainted with the normal intraoperative appearance of a non-recurrent inferior laryngeal nerve. This will undoubtedly be of significance for all of those performing invasive diagnostic and surgical procedures in the neck and upper thoracic regions, in order to minimize the risk of iatrogenic injury to this nerve. This is of extreme importance, since a unilateral lesion of this nerve may result in permanent hoarseness, and a bilateral lesion may lead to aphonia and life-threatening dyspnea.

    The risk factors of hypoparathyroidism after total thyroidectomy (TT) with central lymph node dissection (CND) have not been completely defined. The aim of the study was to evaluate the risk factors of hypoparathyroidism after the surgery.We retrospectively reviewed our patients who underwent TT and CND (including lateral lymph node dissection) for thyroid carcinoma between January 2013 and June 2016. According to the postoperative serum levels of parathyroid hormone within 6 months, the patients were divided into normal, transient hypoparathyroidism, and permanent hypoparathyroidism groups. The clinicopathologic characteristics and surgical details were compared among the 3 groups. The risk factors of hypoparathyroidism were investigated by univariate and multivariate analyses.Of the 903 patients, 399 (44.2%) were found to have transient hypoparathyroidism and 10 (1.1%) had permanent hypoparathyroidism. On multivariate analysis, female gender (P hypoparathyroidism; nonuse of carbon nanoparticles (P = .041) and a tumor in the upper pole of thyroid gland (P = .031) were the independent risk factors of permanent hypoparathyroidism. Patients with transient hypoparathyroidism were more likely to develop permanent hypoparathyroidism when they had hypertension (P = .026) and a tumor in the upper pole of thyroid gland (P = .010).Precise surgical techniques and carbon nanoparticles suspension should be applied for in situ preservation of parathyroid glands (PGs) in thyroid carcinoma patients, especially in females with hypertension and a tumor in the upper pole of thyroid gland. Autotransplantation is only performed when a PG is resected inadvertently or devascularized. TT with BCND should be better performed by an experienced surgeon to reduce the incidence of hypoparathyroidism.

    Cervical spondylosis is degeneration of the cervical spine that occurs during the normal course of aging, and may progress into compression of the spinal cord, or cervical spondylotic myelopathy (CSM), which can cause neurologic dysfunction. Cervical spondylosis can be identified in the majority of people older than 50 years. Many people with cervical spondylosis or CSM are asymptomatic. However, patients with CSM are at higher risk of spinal cord injury (SCI) following minor injury.A 60-year-old woman with asymptomatic cervical spondylosis underwent an elective subtotal thyroidectomy for thyroid nodules. After the surgery, she developed tetraplegia. MRI revealed spinal cord compression and injury. Main diagnoses, therapeutics interventions, and outcomes: Acute cervical SCI was diagnosed. After an emergency anterior cervical corpectomy and fusion surgery, she almost completely recovered.Iatrogenic cervical SCI after nonspinal surgeries that requires neck hyperextension is rarely reported, probably due to underdiagnosis and underreport. Among the 14 cases (including ours) published in the literature, most patients had cervical spondylosis and were senior men. Five patients had diabetes. Four patients had long-term hemodialysis. Seven patients had undergone coronary artery bypass surgery that requires prolonged operative time. Only 3 patients had almost complete recovery. Most patients were disabled. Two patients required tracheostomy for long-term ventilator support. Two patients died. These cases reiterate the potential risk of iatrogenic SCI in people with predisposing conditions such as cervical spondylosis, especially considering the rising prevalence and severity of cervical spondylosis caused by the aging of the population and modern sedentary lifestyle. Surgeries requiring prolonged neck hyperextension put patients with cervical spondylosis at risk for SCI. Failure to recognize the potential occurrence of iatrogenic SCI might endanger patients' lives.

    Full Text Available BackgroundIn esthetic surgery, understanding the factors that influence patient satisfaction is important for successful practice. We hypothesize that the factors that influence patient satisfaction include not only aesthetic and functional outcomes, but also personal factors such as the level of familiarity with factors affecting wound healing and expectations regarding aesthetic outcome.MethodsOne hundred patients who underwent esthetic closure after thyroidectomy were included in this study. In order to evaluate the individual characteristics of the patients, a preoperative survey was administered to the patients. We estimated the patient satisfaction six months postoperatively and assessed the aesthetic and functional outcomes using the Patient and Observer Scar Assessment Scale.ResultsAccording to the results of correlation analysis, level of familiarity with wound healing factors had a positive correlation with satisfaction. High expectations, pain, itching, and high observer scale score had negative correlations with satisfaction. The factors that were correlated with satisfaction were included in the multiple regression analysis. Level of familiarity with wound healing factors was found to have a positive relationship with satisfaction, while itching and observer scale were found to have a negative relationship with satisfaction. After excluding 10 patients who had hypertrophic scars, only level of familiarity with wound healing factors and expectations affected satisfaction.ConclusionsThe level of familiarity with factors affecting wound healing and expectations were found to independently affect satisfaction. Improving patients' level of familiarity with wound healing factors and reducing their expectations by providing suitable preoperative education has the potential to improve patient satisfaction.

    Thyroid carcinoma (TC) is more likely to occur in young women. The aim of this study was to compare the aesthetic effect of different thyroidectomies. One hundred twenty female patients who underwent thyroidectomy were evenly distributed into three groups: conventional access (CA), aesthetic principles access (APA) and minimally invasive access (MIA). The Patient and Observer Scar Assessment Scale (POSAS) was used as the assessment tool for the linear scar. The patients in the MIA group showed significantly less intraoperative blood loss, less drainage, a shorter scar length and a shorter duration of drainage than those in the CA group and the APA group. However, the operation time of 129.0 min in the MIA group was significantly longer than the 79.6 min in the CA group and the 77.0 min in the APA group. The best aesthetic score, as assessed by the Observer Scar Assessment Scale (OSAS), was obtained in the APA group. The Patient Scar Assessment Scale (PSAS) scores were significantly lower in the APA group and CA group than in the MIA group. Significantly lower objective scar ratings were found in the APA group than in the other two groups. These results show that APA produced the best surgical outcomes in TC patients, indicating that conventional thyroidectomy can produce an ideal aesthetic result using the principles of aesthetic surgery. Thyroid surgery need not be performed through excessively short incisions for the sake of patient satisfaction with the scar's appearance. This clinical trial was retrospectively registered on ClinicalTrials.gov PRS on August 1st,2017 ( NCT03239769 ).

    Full Text Available Abstract Background Currently, data are not available concerning a safe insufflation pressure that provides a proper view of the surgical field without adverse metabolic and hemodynamic changes in humans undergoing the robot-assisted thyroidectomy bilateral axillo-breast approach (BABA using the da Vinci robotic surgical system. The purpose of this study was to determine the optimal carbon dioxide (CO2 insufflation pressure in patients with various benign and malignant thyroid diseases when using the da Vinci robotic surgical system. Methods A total of 32 patients underwent thyroid surgery at 6 (n = 15, 9 (n = 15, and 12 (n = 2 mmHg. The partial pressure of carbon dioxide (PaCO2, pH, cardiac output, heart rate, and mean arterial pressure were measured at baseline, 30 min and 1, 1.5, and 2 hours after CO2 insufflation, and 30 min after desufflation. Results CO2 insufflation of 12 mmHg caused severe facial subcutaneous emphysema, hypercarbia, and acidosis during robot-assisted thyroidectomy with BABA. The study was stopped before completion for the patients’ safety in accordance with the study protocol. Applying 6- or 9- mmHg of CO2 insufflation pressure caused increases in PaCO2 and decreases in arterial pH. However, vital signs were stable and pH and PaCO2 were within the physiologic range during the surgery in the 6- and 9-mmHg groups. Conclusions We propose that a CO2 insufflation pressure under 10 mmHg in robot-assisted thyroidectomy with BABA is the optimal insufflation pressure for patient safety.

    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.

    Radiothyroidectomy protected against 2,3,7,8-tetrachloro dibenzo-p-dioxin (TCDD)-induced immunotoxicity in rats as assessed by the spleen anti-SRBC plaque-forming cell assay. Thyroxin (T/sub 4/) replacement therapy partially reversed the effects of thyroidectomy on T/sub 4/ and triiodothyronine (T/sub 3/) serum levels, body weight and immune function as well as restored TCDD-induced immunotoxicity. Thus, hypothyroidism induced by TCDD exposure can be viewed as a protective response of the organism to reduce the insult caused by TCDD.

    This study was designed to evaluate the effect of subtotal thyroidectomy and/or radioactive iodine therapy on plasma immunocalcitonin (iCT) levels and bone densities in patients treated for Graves' disease. Forty-eight women whose ages ranged from 29 to 79 years (mean, 55 years) were evaluated. All were at least 10 years beyond treatment. Fourteen patients had undergone subtotal thyroidectomy, 22 had received radioactive iodine therapy, and 12 had received both. Serum calcitonin levels were measured with the patient fasting and at 30 minutes and 2 hours after the ingestion of 15 mg of calcium in orange juice. Single photon absorptiometry was used to measure bone mineral density of the middle and distal radius. The mean fasting plasma levels of iCT for patients undergoing subtotal thyroidectomy was 27 +/- 2 mumol/L; women treated with radioactive iodine, 26 +/- 2; women undergoing subtotal thyroidectomy followed by radioactive iodine, 24 +/- 2, and for normal control women, 48.5 +/- 4.7. The mean stimulated iCT level of each of the patient groups was significantly lower than that of the normal controls (p = 0.01). There were no significant differences among the groups. Although there was an increased loss of bone mineral density in postmenopausal patients, with age and race as covariates, the bone densities of the distal radius in women undergoing subtotal thyroidectomy and/or receiving radioactive iodine were not significantly lower than those of normal control subjects (p greater than 0.05). These findings are consistent with other observations that patients treated by thyroidectomy and/or radioactive iodine for Graves' disease have lower basal levels of calcitonin and decreased calcitonin response to a provocative stimulus. Whether this loss of calcitonin reserve is a significant factor in development of postmenopausal osteoporosis remains unanswered.

  12. 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.

  20. Remission of anorexia nervosa after thyroidectomy: A report of two cases with Graves' disease and anorexia nervosa

    2011-12-01

    Full Text Available Abstract We report two patients with anorexia nervosa and Graves' disease who received subtotal thyroidectomy for Graves' disease and concomitantly experienced remission from anorexia nervosa. Both were young women (aged 20 and 26 at the time of surgery. Both had well controlled thyroid function and eating behavior at the time of surgery. Both were followed for over five years without relapse of anorexia nervosa or hyperthyroidism. These cases suggest the existence of an endocrine factor originating from the thyroid gland that is involved in the pathogenesis of anorexia nervosa. Since patients of thyroidectomy can remain in good health with supplement of thyroxine alone, it can be hypothesized that this anorexigenic endocrine factor is an evolutionary relic not necessary for the normal function of humans and does not have physiological effects unless secreted beyond normal levels. Given that, it implies the existence of a creature in the animal kingdom for which such an anorexigenic hormone is essential for survival. Migrating birds eat beyond their caloric expenditure before migration and become anorexic for the duration of their flight. It is also known that their thyroid function is elevated during migration. The normal physiology of migration is a complex mechanism involving the hypothalamic, pituitary, thyroid, adrenal and reproductive hormones. The mechanism of disease, however, can be simpler. A review of the literature is presented that suggest a heretofore unreported thyroid hormone, which is involved in the regulation of migration behavior, may be the responsible factor behind anorexia nervosa.

    The American Thyroid Association recommends lymph node mapping (LNM) ultrasonography 6-12 months after thyroidectomy for patients with papillary thyroid cancer (PTC). The yield of LNM over thyroglobulin (TG) screening is not well defined. We sought to investigate this relationship. Post thyroidectomy LNM was performed on 163 patients with PTC. LNM was considered positive based on these criteria: Loss of fatty hilum (LOFH), microcalcifications, hypervascularity, architectural distortion, or short axis (>8 mm). Serum TG levels were compared to LNM and fine needle aspiration (FNA). Sixty-nine patients had suspicious LNM (42%) and 17 had PTC on FNA (25%). There were 135 suspicious lymph nodes described with malignant nodes found in 6 of 65 patients (9%) with LOFH, 13 of 18 patients (76%) with microcalcifications, 11 of 12 patients (92%) with hypervascularity, 16 of 28 patients (52%) with architectural distortion, and 4 of 7 patients (52%) with enlarged size on FNA. The positive predictive value of LNM was 0.34, increasing to 0.66 when LOFH was excluded. Among 152 patients with documented TG data, LNM identified cervical nodal metastasis in 4 patients with TG < 0.5 pg/mL (anti-TG antibody negative, thyroid-stimulating hormone suppressed). Of the 15 patients with positive anti-TG antibody, 3 with recurrence were found on LNM. LNM can detect recurrent PTC when TG level is undetectable, and LOFH is a low-yield sonographic characteristic.

    Full Text Available A variety of electromyography (EMG recording methods were reported during intraoperative neural monitoring (IONM of recurrent laryngeal nerve (RLN in thyroid surgery. This study compared two surface recording methods that were obtained by electrodes on endotracheal tube (ET and thyroid cartilage (TC. This study analyzed 205 RLNs at risk in 110 patients undergoing monitored thyroidectomy. Each patient was intubated with an EMG ET during general anesthesia. A pair of single needle electrode was inserted obliquely into the TC lamina on each side. Standard IONM procedure was routinely followed, and EMG signals recorded by the ET and TC electrodes at each step were compared. In all nerves, evoked laryngeal EMG signals were reliably recorded by the ET and TC electrodes, and showed the same typical waveform and latency. The EMG signals recorded by the TC electrodes showed significantly higher amplitudes and stability compared to those by the ET electrodes. Both recording methods accurately detected 7 partial loss of signal (LOS and 2 complete LOS events caused by traction stress, but only the ET electrodes falsely detected 3 LOS events caused by ET displacement during surgical manipulation. Two patients with true complete LOS experienced temporary RLN palsy postoperatively. Neither permanent RLN palsy, nor complications from ET or TC electrodes were encountered in this study. Both electrodes are effective and reliable for recording laryngeal EMG signals during monitored thyroidectomy. Compared to ET electrodes, TC electrodes obtain higher and more stable EMG signals as well as fewer false EMG results during IONM.

    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.

    Subclinical hypothyroidism has been linked to increased risk of atherosclerotic disease. Soluble CD40 ligand (sCD40L), mainly derived from activated platelets, and the lipid peroxidation product 8-iso-prostaglandin F 2α (8-iso-PGF 2α ) are known to play a relevant pathophysiological role in atherogenesis. In this study, we analyzed the relationship between thyroid hormones and circulating levels of sCD40L and 8-iso-PGF 2α in patient with recent-onset post-thyroidectomy subclinical hypothyroidism under replacement therapy. Circulating levels of thyroid hormones, sCD40L, and 8-iso-PGF 2α were assessed in 40 recently thyroidectomized patients (33 females, mean age 52.0 ± 11.7 years) at baseline (5-7 day after surgery) and after 2 months under replacement therapy with levothyroxine (LT-4). At baseline, circulating levels of thyroid hormones were indicative of a subclinical hypothyroidism (TSH 7.7 ± 3.9 μU/mL, FT3 1.8 ± 0.6 pg/mL, and FT3 8.9 ± 3.0 pg/mL). Circulating levels of sCD40L and 8-iso-PGF 2α were directly correlated with each other (r = 0.360, p = 0.023) and with TSH levels (r = 0.322, p = 0.043 and r = 0.329 p = 0.038, respectively). After 2 months under the replacement therapy with LT-4 circulating levels of TSH (from 7.7 ± 3.9 to 2.7 ± 2.8 μU/mL, p hypothyroidism to develop atherosclerotic disease.

    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.

    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.

    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.

  10. 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.

    Total thyroidectomy is a preferred surgical technique for benign as well as malignant thyroid pathologies, but many a times can cause hypoparathyroidism. The aim of this study is to evaluate the intra-operative parathyroid hormone (ioPTH) level and its decline as predictors for post-operative hypoparathyroidism after total thyroidectomy. In this single-centre prospective cohort study, 90 patients who underwent total thyroidectomy for benign as well as malignant pathologies of thyroid gland were studied. Intra-operative parathyroid levels and at different time intervals parathyroid hormone and serum calcium levels were measured to predict hypoparathyroidism. The data was analysed using independent sample t test and p value hypoparathyroidism. Intra-operative PTH was found to be most accurate predictor for diagnosing post-operative hypoparathyroidism (cut off was (11.3 pg/ml, calculated using ROC curves) and has maximum sum of sensitivity (91.7%) and specificity (97%). On taking cut off values of intra-operative PTH and PTH decline together, they were found to be most accurate predictor for permanent hypoparathyroidism. Early and accurate predictor of hypoparathyroidism is very important and always sought. Very early prediction during intra-operative periods can be used for auto transplantation of parathyroid gland. Intra-operative parathyroid hormone and its decline are accurate, reliable, and early predictor of hypoparathyroidism after total thyroidectomy. Copyright © 2015 IJS Publishing Group Limited.

    Kim, Yong Sik; Kim, Chul Young; Chun, Hoon Jai

    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.

    2010-02-01

    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.

    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.

    Full Text Available BACKGROUND: We carried out a systematic review and meta-analysis to evaluate the impact of prophylactic dexamethasone on post-operative nausea and vomiting (PONV, post-operative pain, and complications in patients undergoing thyroidectomy. METHODS: We searched Pubmed, Embase, and Cochrane Library databases for randomized controlled trials (RCTs that evaluated the prophylactic effect of dexamethasone versus placebo with or without other antiemetics for PONV in patients undergoing thyroidectomy. Meta-analyses were performed using RevMan 5.0 software. RESULTS: Thirteen RCTs that considered high quality evidence including 2,180 patients were analyzed. The meta-analysis demonstrated a significant decrease in the incidence of PONV (RR 0.52, 95% CI 0.43 to 0.63, P < 0.00001, the need for rescue anti-emetics (RR 0.42, 95% CI 0.30 to 0.57, P<0.00001, post-operative pain scores (WMD -1.17, 95% CI -1.91 to -0.44, P = 0.002, and the need for rescue analgesics (RR 0.65, 95% CI 0.50-0.83, P = 0.0008 in patients receiving dexamethasone compared to placebo, with or without concomitant antiemetics. Dexamethasone 8-10mg had a significantly greater effect for reducing the incidence of PONV than dexamethasone 1.25-5mg. Dexamethasone was as effective as other anti-emetics for reducing PONV (RR 1.25, 95% CI 0.86-1.81, P = 0.24. A significantly higher level of blood glucose during the immediate post-operative period in patients receiving dexamethasone compared to controls was the only adverse event. CONCLUSIONS: Prophylactic dexamethasone 8-10mg administered intravenously before induction of anesthesia should be recommended as a safe and effective strategy for reducing the incidence of PONV, the need for rescue anti-emetics, post-operative pain, and the need for rescue analgesia in thyroidectomy patients, except those that are pregnant, have diabetes mellitus, hyperglycemia, or contraindications for dexamethasone. More high quality trials are warranted to define the

    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.

    2015-01-01

    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.

    1994-01-01

    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

    2016-12-01

    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.

    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.

    After thyroidectomy, the goal of the first dose of radioactive iodine (RAI) is remnant ablation to facilitate the initial staging with the post-therapy scan and to facilitate the early detection of recurrences. The purpose of this study is to the survival benefit of RAI in low-risk thyroid cancer patients. Using Cancer thyroid registry of Marne Ardennes (1041 patients) and hospital data base of centre Leclerc (257 patients), we included all differentiated thyroid cancer (DTC) patients at low risk from 1975 to 2005. Median follow-up was 10.3 years, during which 19 recurrences, 61 other malignant diseases and 105 deaths were registered. 387 patients (30%) received no RAI and 911 had RAI (70%). If we confirmed that some clinical characteristics were associated with RAI intake, the study failed to demonstrate any survival benefit of RAI in low risk DTC patients

    Thyroidectomy continues to pose the risk of typical complications, including postoperative hypocalcemia and permanent hypoparathyroidism. The strategic decision on how to preserve parathyroid hormone (PTH) secretion relies on assessing the viability of the parathyroid glands (PGs). The aim of this study was to assess parathyroid discoloration as an indicator for loss of parathyroid function. The prospective study included 29 patients (24 women, 5 men; age 53.2 ± 13.0 years) who underwent near-total or total thyroidectomy. An intra- and postoperative PTH and calcium monitoring was performed. The intraoperative situs of the PGs was documented by a study protocol. The patients were grouped in three categories: group A, 12 patients with four visualized and normally colored PGs; group B, 13 patients with four visualized and three or four discolored PGs; group C, 4 patients who had undergone autotransplantation of two PGs. Compared to group A, groups B and C showed sharper intraoperative PTH declines. PTH values recovered more quickly in group B than in group C. However, no significant differences in PTH kinetics were found in the general linear model for repeated measures (p = 0.132). However, a significantly higher incidence of protracted hypocalcemia-related symptoms for more than 14 postoperative days was found for group C (50.0%) than for groups A (0%) and B (0%; p = 0.011). None of the patients developed permanent hypoparathyroidism. The function of discolored PGs is only transiently impaired and recovers within a short time after surgery. Our observations do not support autotransplantation as a generally applicable first-line intervention for discolored PGs in the absence of other criteria for autotransplantation.

    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.

    Per-oral endoscopic myotomy (POEM) was developed less than a decade ago for the treatment of achalasia. Its minimally invasive approach and the favorable short-term outcome have led to rapid adoption of the technique throughout the world. As with any new technique, there will be adverse events, and it is important that effective treatments for these adverse events be discussed.

    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

    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.

    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.

  18. Update on the endoscopic treatments for achalasia.

    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.

    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.

  9. Endoscopic treatment of vesicoureteral reflux: Current status

    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.

    2014-01-01

    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.

    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.

    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.

  15. Endoscopic management of biliary injuries and leaks

    T S Chandrasekar

    2012-01-01

    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.

    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

    A 65-year-old patient, with a history of left hemi-thyroidectomy for adenomatous goiter 20 years previously, was found to have pulmonary lesions on chest X-ray, a brain lesion on computerized tomography (CT), and elevated serum thyroglobulin (Tg). While completion thyroidectomy revealed that no pathological evidence of thyroid malignancy, radioiodine-avid pulmonary, brain, and renal and bone lesions were identified on diagnostic as well as posttherapy whole body planar scintigraphy and single photon emission computed tomography-CT. Subsequent ultrasonography-guided biopsy of a renal nodule showed thyroid follicular cells. This case suggests that metastatic differentiated thyroid carcinoma should be suspected in asymptomatic patients with incidentally detected lesions, raised serum Tg, and history of thyroid lesions

    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.

    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.

    The rate and impact of thyroglossal duct remnant (TGDR) visualization in patients with hypothyroidism after total thyroidectomy for differentiated thyroid carcinoma (DTC) have not yet been fully determined. The aim of this study was to assess the rate of TGDR visualization in post total thyroidectomy whole body scan (WBS) for DTC and to evaluate its impact on the outcome of I-131 ablation. A total of 60 consecutive DTC patients (51 papillary thyroid Ca., and 9 Follicular thyroid Ca.), underwent total thyroidectomy, followed by WBS (using I-131 in 28 patients and I-123 in 32 patients), neck ultrasound (US), thyroglobulin (Tg) and Tg anti-bodies (TgAb) assay after 40 days and subsequent I-131 ablation. At 6 months later follow-up I-131 WBS, neck U/S, Tg and TgAb were performed following suspension of L-thyroxine for 1-month (thyroid stimulating hormone [TSH] >30 μIU/ml) in 53 patients and following recombinant human TSH stimulation in seven patients. Of the studied 60 patients, 19/60 (31.7%) had a linear or focal radioactivity at the superior midline of the neck, suggesting TGDR (Group 1), and 41/60 (68.3%) had no uptake to suggest TGDR (Group 2). No significant difference regarding age, gender and histopathology between both groups. Neck US showed no evidence of thyroid tissue in the superior midline of the neck in both groups, and only a small or no residual thyroid tissue in patients of Group 1. There was a significant successful I-131 ablation rate among patients of group 1 compared to group 2 (79% in Group 1 vs. 41.5% in Group 2) (P = 0.007). Thyroglossal duct remnant visualization on WBS of hypothyroid subjects after total thyroidectomy suggests presence of only a small or no residual functioning thyroid tissue at the thyroid bed and can predict a good response to I-131 ablation

    Objective: This prospective study evaluated the recurrence rate in low-risk patients with papillary thyroid cancer (PTC) who presented slightly elevated thyroglobulin (Tg) after thyroidectomy and who did not undergo ablation with {sup 131}I. Subjects and methods: The study included 53 low-risk patients (non aggressive histology; pT1b-3, cN0pNx, M0) with slightly elevated Tg after thyroidectomy (> 1 ng/mL, but ≤ 5 ng/mL after levothyroxine withdrawal or ≤ 2 ng/mL after recombinant human TSH). Results: The time of follow-up ranged from 36 to 96 months. Lymph node metastases were detected in only one patient (1.9%). Fifty-two patients continued to present negative neck ultrasound. None of these patients without apparent disease presented an increase in Tg. Conclusions: Low-risk patients with PTC who present slightly elevated Tg after thyroidectomy do not require ablation with {sup 131}I. (author)

    The external branch of the superior laryngeal nerve (SLN) is susceptible to injuries during thyroidectomy, causing voice impairment. Intraoperative nerve monitoring may facilitate identification of the nerve, reducing voice impairment. A total of 252 patients undergoing thyroidectomy were randomly assigned to group N (the NIM-Response 3.0 system was used) or group C (the conventional technique using the Vari-Stim 3 was used) to identify the external branch of the SLNs. The primary endpoint was the identification rate of the external branch of the SLN. The secondary endpoint was the incidence of postoperative voice impairment. The visual and the electrostimulatory identification rates of the external branch of the SLN in group N and group C were 48.8% versus 17.8% (p < .001) and 89.2% versus 17.8% (p < .001), respectively. The proportion of female patients who had subjective voice impairment was significantly smaller in group N than in group C. The use of the NIM-Response 3.0 significantly improved the identification rate of the external branch of the SLN during thyroidectomy, reducing voice impairment. © 2014 Wiley Periodicals, Inc.

    Objective: To elucidate the necessity of Lugol’s iodine in preoperative preparation of patients undergoing thyroidectomy. Materials and Methods: Hundred and five euthyroid patients who underwent surgery without preoperative preparation of patients with Lugol’s iodine were enrolled in this retrospective study conducted during the period May 2009 to August 2013 in Teaching Hospital. Indication of surgery was ranging from suspected malignancy to cosmetic reasons and compressive features like dysphagia , dyspnoea and hoarseness of voice. Results: All patients were operated by the same surgeon where in hemi, total and subtotal thyroidectomies were performed without any usage of Lugol’s iodine preoperatively. During the postoperative period the following events occurred, five patients (4.7%) had incurred recurrent laryngeal nerve palsy (RLNP) which was confirmed with postoperative indirect laryngoscopic examination and two patients (1.9%) with hypocalcemia (serum calcium less than 8mg/dl) which was managed conservatively and effectively. Among these five patients, three patients had (Right RLNP) and two patients had (Left RLNP) palsies. Of these four RLNP (3.8%) were temporary which improved with conservative management within 3weeks-6months duration and one (0.9%) was a permanent Rt RLNP with no improvement even after six months. Conclusion: Hence, we conclude that it is not of much importance to use Lugol’s iodine preoperatively in patients undergoing thyroidectomy. There does not appear any convincing evidence of advantages of preoperative preparation of patients with lugol’s iodine in euthyroid state undergoing surgery. PMID:25302223

    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.

Patients and methods. From 345 consecutive DTC patients after thyroidectomy and radioiodine ablation we select ed 148 patients with elevated TgAb level (with distant metastasis n = 93, without distant metastasis n = 55. Serum TgAb concentration was measured before radioiodine ablation and then every time before 131I treatment (RIT or diagnostic 131I whole body scanning (WBS. Results were compared with serum thyroglobulin (Tg concentration, neck echography, lung and bone roentgenography and 131I WBS findings. Results. TgAb level was elevated in 21% DTC patients before 131I ablation. The other 22% with initially normal TgAb displayed their rising during followup. In absence of distant metastasis TgAb declined after 1 st–2 nd cycle of RIT (an average 8.9 months after 131I ablation. Persistance or rising of TgAb in the longer term was associated with detectable thyroid remnant, residual tumor or metastatic lymph nodes. In case of negative TgAb status after sugery an increase of TgAb during first 3–6 months after ablation indicated mostly a response to the rise of Tg antigen secondary to 131I ablation. A rise TgAb in the longer term (after 3rd–5th cycles of RIT indicated to residual or recurrent disease in 86% cases. In patients with distant metastasis there were no correlation between change in TgAb concentration and clinical sta tus, including the rate of regression of metastatic disease. But in case of low or undetectable Tg and permanent high TgAb level only TgAb indicated the presence of disease. Conclusion: persistence or rising TgAb in longer term after 131I ablation can serve as surrogate tumor marker of per sistent or recurrent disease. It is critical to measure TgAb concentration, especially in patients with low or unde tectable Tg, because

    The best method of preventing hypoparathyroidism after thyroidectomy is to keep parathyroid glands in situ. However, hypoparathyroidism still regularly occurs with the existing parathyroid classification system, and the incidence of permanent hypoparathyroidism has not been reduced. We created a novel system for classifying parathyroid glands that can guide parathyroid preservation in thyroidectomy.We prospectively observed parathyroid glands using the new system in 218 neck surgeries, compared with 132 under the traditional system from January 2014 to September 2015 at a single clinic center. Briefly, we classified parathyroid glands as follows: Type A, no dependency on the thyroid; B1, partial blood supply from the thyroid but retains adequate blood supply after removal of the thyroid; B2, partial blood supply from the thyroid and becomes devascularized after the removal of the thyroid; B3, blood supply mostly from the thyroid; and C, blood supply completely dependent on the thyroid. The classifications were used to decide between in situ preservation or auto-transplantation.The most common type of parathyroid gland was type B1 (53.77%), followed by type A (20.89%), which are the perfect categories for in situ preservation. Type B2 (17.52%) and type B3 (1.21%) have a chance to be kept in situ. For type C (6.61%), in situ preservation is impossible. When in-situ preservation is ruled out, parathyroid auto-transplantation is an alternative, with partial or total gland tissue, depending on the classification and the surgeon's discretion. Among the patients who were classified under the new system, 43.6% presented with transient hypoparathyroidism (symptoms lasting ≤6 months) after surgery, versus 42.4% in the old system, which was not a significant difference. However, permanent hypothyroidism (symptoms lasting >6 months) was not detected in the applied group, but in 3.0% of patients in the nonapplied group (P = 0.01).Our novel functional nomenclature system

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.

    Compare the result of endoscopic versus open bursectomy in lateral malleolar bursitis. Prospective evaluation of 21 patients (22 ankles) undergoing either open or endoscopic excision of lateral malleolar bursitis. The median age was 64 (38-79) years old. The median postoperative follow-up was 15 (12-18) months. Those patients undergoing endoscopic excision showed a higher satisfaction rate (excellent 9, good 2) than open excision (excellent 4, good 3, fair 1). The wounds also healed earlier in the endoscopic group although the operation time was slightly longer. One patient in the endoscopic group had recurrence of symptoms but complications in the open group included one patient with skin necrosis, one patient with wound dehiscence, and two patients of with superficial peroneal nerve injury. Endoscopic resection of the lateral malleolar bursitis is a promising technique and shows favorable results compared to the open resection.

    Disorders of gastric outflow and outlet obstruction include a variety of benign and malignant disorders such as peptic strictures, foreign bodies, gastroparesis, and cancers of the stomach, duodenum, and pancreas. Historically, a majority of patients presenting with gastric outlet obstruction (GOO) were to the result of peptic ulcers and surgical management of peptic ulcer complications was a mainstay of general surgical training. Invasive surgery is being performed less frequently today due to realization of the role of Helicobacter pylori in peptic ulcer disease and the introduction of novel endoscopic techniques for management of GOO. For malignant GOO, the introduction of lumen-apposing metal stents have opened the door for the development and performance of endoscopic ultrasound-guided gastric bypass procedures. For benign GOO, including gastroparesis and pyloric stenosis, endoscopic myotomy shows promise. Endoscopic ultrasound-guided gastric bypass, per-oral endoscopic myotomy, and other novel techniques in the endoscopic management of GOO, are discussed in this review.

    Full Text Available Endoscopic treatment is a minimally invasive treatment for managing patients with vesicoureteral reflux (VUR. Although several bulking agents have been used for endoscopic treatment, dextranomer/hyaluronic acid is the only bulking agent currently approved by the U.S. Food and Drug Administration for treating VUR. Endoscopic treatment of VUR has gained great popularity owing to several obvious benefits, including short operative time, short hospital stay, minimal invasiveness, high efficacy, low complication rate, and reduced cost. Initially, the success rates of endoscopic treatment have been lower than that of open antireflux surgery. However, because injection techniques have been developed, a recent study showed higher success rates of endoscopic treatment than open surgery in the treatment of patients with intermediate- and high-grade VUR. Despite the controversy surrounding its effectiveness, endoscopic treatment is considered a valuable treatment option and viable alternative to long-term antibiotic prophylaxis.

    Full Text Available For patients who are unable to meet their nutritional needs orally, enteral feeding via a percutaneous approach has become the mainstay of therapy. However, traditional enteral feeding methods, such as percutaneous endoscopic gastrostomy, may not be viable options for patients with severe gastroparesis or gastric outlet obstruction. Direct percutaneous endoscopic jejunostomy (DPEJ is an enteral access method that was first described more than 20 years ago and has gained popularity among gastroenterologists. This review discusses the indications for and contraindications to DPEJ, the procedure, the application of DPEJ in specific subsets of patients with gastrointestinal disorders, and presents a brief tabular summary of complications and success rates of DPEJ in case series published since 2000.

    Introduction Radiofrequency ablation (RFA) is a well-validated treatment of dysplastic Barrett's esophagus. Other indications of endoscopic RFA are under evaluation. Results Four prospective studies (total 69 patients) have shown that RFA achieved complete remission of early esophageal squamous intra-epithelial neoplasia at a rate of 80%, but with a substantial risk of stricture. In the setting of gastric antral vascular ectasia, two prospective monocenter studies, and a retrospective multicenter study, (total 51 patients), suggest that RFA is efficacious in terms of reducing transfusion dependency. In the setting of chronic hemorrhagic radiation proctopathy, a prospective monocenter study and a retrospective multicenter study (total 56 patients) suggest that RFA is an efficient treatment. A retrospective comparative study (64 patients) suggests that RFA improves stents patency in malignant biliary strictures. Conclusions Endoscopic RFA is an upcoming treatment modality in early esophageal squamous intra-epithelial neoplasia, as well as in gastric, rectal, and biliary diseases. PMID:26279839

    Full Text Available Obesity has become a worldwide epidemic with significant impact on quality of life, morbidity, and mortality rates. Over the past two decades, bariatric surgery has established itself as the most effective and durable treatment for patients with obesity and its associated comorbidities. However, despite the use of minimally invasive techniques, bariatric surgery is associated with complications in approximately 15% of patients, has a substantial cost, and is used by only 1% of patients who are eligible. Therefore, there is a need for effective minimally invasive therapies, which will be utilized by the large proportion of obese patients who are in desperate need of treatment but are not receiving any. Endoscopic approaches to the management of obesity have been developed, with the aim of delivering more effective, durable, and safer methods of weight reduction. In this paper, we review currently available and future endoscopic therapies that will likely join the armamentarium used in the management of obesity.

    2015-01-01

    Endonasal endoscopic sinus surgery is the standard procedure for surgery of most paranasal sinus diseases. Appropriate frame conditions provided, the respective procedures are safe and successful. These prerequisites encompass appropriate technical equipment, anatomical oriented surgical technique, proper patient selection, and individually adapted extent of surgery. The range of endonasal sinus operations has dramatically increased during the last 20 years and reaches from partial uncinectomy to pansinus surgery with extended surgery of the frontal (Draf type III), maxillary (grade 3–4, medial maxillectomy, prelacrimal approach) and sphenoid sinus. In addition there are operations outside and beyond the paranasal sinuses. The development of surgical technique is still constantly evolving. This article gives a comprehensive review on the most recent state of the art in endoscopic sinus surgery according to the literature with the following aspects: principles and fundamentals, surgical techniques, indications, outcome, postoperative care, nasal packing and stents, technical equipment.

    2016-03-01

    Full Text Available Portal biliopathy is defined as abnormalities in the extra- and intrahepatic ducts and gallbladder of patients with portal hypertension. This condition is associated with extrahepatic venous obstruction and dilatation of the venous plexus of the common bile duct, resulting in mural irregularities and compression of the biliary tree. Most patients with portal biliopathy remain asymptomatic, but approximately 10% of them advance to symptomatic abdominal pain, jaundice, and fever. Magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography are currently used as diagnostic tools because they are noninvasive and can be used to assess the regularity, length, and degree of bile duct narrowing. Management of portal biliopathy is aimed at biliary decompression and reducing the portal pressure. Portal biliopathy has rarely been reported in Korea. We present a symptomatic case of portal biliopathy that was complicated by cholangitis and successfully treated with biliary endoscopic procedures.

    Full Text Available Wide field fundus imaging is needed to diagnose, treat, and follow-up patients with retinal pathology. This is more applicable for pediatric patients as repeated evaluation is a challenge. The presently available imaging machines though provide high definition images, but carry the obvious disadvantages of either being costly or bulky or sometimes both, which limits its usage only to large centers. We hereby report a technique of fundus imaging using a nasal endoscope coupled with viscoelastic. A regular nasal endoscope with viscoelastic coupling was placed on the cornea to image the fundus of infants under general anesthesia. Wide angle fundus images of various fundus pathologies in infants could be obtained easily with readily available instruments and without the much financial investment for the institutes.

    In this review, we describe the FDA-approved and investigational devices and endoscopic bariatric therapies for the treatment of obesity. We focus on literature published in the past few years and present mechanisms of action as well as efficacy and safety data. Devices and endoscopic procedures are emerging options to fill the significant treatment gap in the management of obesity. Not only are these devices and procedures minimally invasive and reversible, but they are potentially more effective than antiobesity medications, often safer for poor surgical candidates and possibly less expensive than bariatric surgery. As many patients require a variety of management strategies (medications, devices, procedures, and/or surgery) in addition to lifestyle modifications to achieve clinically significant weight loss, the future of obesity treatment involves a multidisciplinary approach. Combinations of advanced treatment strategies can lead to additive or synergistic weight loss. This is an area that requires further investigation.

    Full Text Available Intrasheath subluxation of the peroneal tendons within the peroneal groove is an uncommon problem. Open exploration combined with a peroneal groove-deepening procedure and retinacular reefing is the recommended treatment. This extensive lateral approach needs incision of the intact superior peroneal retinaculum and repair afterwards. We treated three patients with a painful intrasheath subluxation using an endoscopic approach. During this tendoscopy both tendons were inspected. The distal muscle fibers of the peroneus brevis tendon were resected in two patients. A partial tear was debrided in the third patient. All patients had a good result. No wound-healing problems or other complications occurred. Early return to work and sports was possible. An endoscopic approach was successful in treatment of an intrasheath subluxation of the peroneal tendons.

    The palliative treatment of tumorous stenosis of the esophagus and cardio-esophageal region by intubation with an endoprosthesis leads to an improved quality of life. The used endoscopic positioning provides better results than the surgical procedure. This method is easy in handling and has only few complications. The endoscopic positioning of endoprosthesis is also a really alternative of alimentary fistula. The positioning of plastic prosthesis under endoscopic control should be given preference in the palliative treatment of obstructing cardio-esophageal malignancy.

    2016-01-01

    Endoscopic resection of early gastric cancer is defined as incomplete when tumor cells are found at the resection margin upon histopathological examination. However, a tumor-positive resection margin does not always indicate residual tumor; it can also be caused by tissue contraction during fixation, by the cautery effect during endoscopic resection, or by incorrect histopathological mapping. Cases of highly suspicious residual tumor require additional endoscopic or surgical resection. For in...

    Full Text Available Objective: The aim of this study was to show that endoscopic surgery is a simple and acceptable method for various problems associated with wounds, range of motion and that such surgery ensures an early return to work after treatment of nonresponding nonseptic bursitis. Methods: Thirty-two patients with nonseptic bursitis caused by repeated minor trauma that did not respond to medical treatment from 2008 to 2012 were included in this study. Radiographic [anteroposterior and lateral], ultrasound, macro and microscopic analyses of drainage liquid and aerobic and anaerobic cultures were obtained from the patients for the diagnosis. Results: The mean age was 40.8 years. Fifteen patients had prepatellar bursitis, 13 had olecranon bursitis and 4 had ankle bursitis. Two patients had a history of falling on their knee. The other patients had a history of repetitive stimulation .The mean follow up period was 2.6 years [range. 2-5 years] and no medical complications occurred after the endoscopic surgery; such as scarring, loss of sensation and infection. One recurrence in response to medical treatment was observed. Conclusion: Endoscopic bursectomy is a short and acceptable procedure with excellent results in terms of returning to work early and minimal wound related problems.

    Anderson, Jennifer

    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.

    Esophageal achalasia is a chronic and progressive motility disorder characterized by absence of esophageal body peristalsis associated with an impaired relaxation of lower esophageal sphincter (LES) and usually with an elevated LES pressure, leading to an altered passage of bolus through the esophago-gastric junction. A definitive cure for achalasia is currently unavailable. Palliative treatment options provide only food and liquid bolus intake and relief of symptoms. Endoscopic therapy for achalasia aims to disrupt or weaken the lower esophageal sphincter. Intra-sphincteric injection of botulinum toxin is reserved for elderly or severely ill patients. Pneumatic dilation provides superior results than botulinum toxin injection and a similar medium-term efficacy almost comparable to that attained after surgery. Per oral endoscopic myotomy is a promising option for treating achalasia, but it requires increased experience and further objective and long-term follow up. This article will review different endoscopic treatments in achalasia, and summarize the short-term and long-term outcomes.

    To evaluate the results of endoscopic dacryocystorhinostomy (DCR) with or without support of the ophthalmologist. A retrospective study of 100 cases of endoscopic DCR surgery conducted by an otolaryngologist between June 2008 and December 2009. Of the 100 cases, 50 were operated with surgical support of the ophthalmologist, who inserted Bowman probes in the upper and lower canaliculi, while in the other 50 cases it was the otolaryngologist who performed this, without support of the ophthalmologist. The evaluation of the results after 2 years included the subjective perception, the lacrimal patency after lacrimal syringing, and lacrimal functional test after modified Jones test. Of the 100 DCR reviewed, more than 50% required complementary treatment by the otolaryngologist, mainly septoplasty. As for the resolution of epiphora, without support of the ophthalmologist, 75% the patients reported an overall subjective improvement, but this reached 92% in the surgical group with support of the ophthalmologist, which was a statistically significant difference. Endoscopic DCR is effective in the treatment of epiphora, but its results improve when the ophthalmologist inserts the probes in the lacrimal canaliculi during the surgical procedure.

    The availability of miniature imagers enables endoscopic systems with simplified integration. Here, the optical elements together with the imager are located at the distal end of these so called video endoscopes. The overall system can be flexible since no relaying optics is required in order to image the object at a remote position. Compared to conventional flexible systems based on light guiding fiber bundles, higher spatial resolutions can be achieved due to the ever decreasing pixel size in CMOS imager fabrication technology. We propose system designs and prototypes for f/4, 3mm outer diameter endoscopes with 70° and 110° field of view using a CMOS imager with 650x650 pixels of 2.8μm pitch. The systems are based on a simplified and rugged integration using a single polymer lens made by injection molding, a GRIN lens and a dispensed lens made of UV curing material allowing for high performance paired with low fabrication cost allowing for the usage as a disposable unit. Additionally, a side view system angled at 30° is presented based on a tilting reflection prism requiring minimum construction space allowing for an outer diameter of 3mm.

    In order to reduce the miss rate of the wireless capsule endoscopy, in this paper, we propose a new system of the endoscopic capsule with multiple cameras. A master-slave architecture, including an efficient bus architecture and a four level clock management architecture, is applied for the Multiple Cameras Endoscopic Capsule (MCEC). For covering more area of the gastrointestinal tract wall with low power, multiple cameras with a smart image capture strategy, including movement sensitive control and camera selection, are used in the MCEC. To reduce the data transfer bandwidth and power consumption to prolong the MCEC's working life, a low complexity image compressor with PSNR 40.7 dB and compression rate 86% is implemented. A chipset is designed and implemented for the MCEC and a six cameras endoscopic capsule prototype is implemented by using the chipset. With the smart image capture strategy, the coverage rate of the MCEC prototype can achieve 98% and its power consumption is only about 7.1 mW.

    1993-07-01

    Endoscopy has become an important procedure in many medical specialties. For the Otologist, however, space limitations within the ear have restricted development of endoscopic procedures. The desire for minimally invasive techniques in Otology has demonstrated itself through the work of numerous physicians who have performed procedures ranging from diagnostic inspection of the middle ear to viewing the interior of the cochlea. To assist in performing such endoscopic procedures, Xomed-Treace has developed a line of flexible fiberoptic endoscopes for use by the Otologist. These scopes combine illumination and imaging fiber bundles within a small diameter unit ranging in size from 0.8 mm to 1.2 mm. The 1.2 mm scope is produced with an angled, rigid stainless steel sheath. The 0.8 mm scope is flexible with the ability to articulate 120 degree(s) in one direction. The fiberscopes have been designed for the Otologist to produce a good resolution image while allowing ease of operation through ergonomics and consideration of the surgical anatomy.

    With the recent changes of pathological concepts, colorectal serrated lesions can be now divided into traditional serrated adenoma, typical hyperplastic polyp and sessile serrated polyp. The aim of this study is to clarify the endoscopic differences among these three groups. A total number of 362 serrated lesions larger than 5mm were evaluated. These were detected with ordinary view and observed also with magnifying chromoendoscopic view. The final pathologic diagnosis of the resected specimens was made blinded. There were significant differences between traditional serrated adenoma and sessile serrated polypconcerning location, configuration and color. In chromoendoscopy, most of sessile serrated polyps and typical hyperplastic polyps showed star-like pattern, in contrast with traditional serrated adenomas most of which had fernor pinecone-like pattern. The differential diagnosis between traditional sessile polyp and the other two was possible with high accuracy. On the other hand, endoscopic distinction between sessile serrated polyp and typical hyperplastic polyp was not easy, except that the location and size were significantly different. We can endoscopically differentiate between traditional serrated adenoma and sessile serrated polyp or typical hyperplastic polyp, but it is difficult to differentiate between the latter two.

    Synovial lipoma of the patellar tendon is a very rare entity. It can be associated with rupture of the patellar tendon. We present a case of synovial lipoma that was successfully resected endoscopically. The other indications for patellar tendoscopy include chronic patellar tendinitis and tendinosis, recalcitrant bursitis around the tendon, Osgood-Schlatter disease, and jumper's knee. The major potential danger of this endoscopic procedure is iatrogenic damage to the patellar insertion during endoscopic debridement in patients with jumper's knee or the tibial insertion during endoscopic debridement in patients with Osgood-Schlatter disease.

    Variceal bleeding is a life-threatening complication of portal hypertension with a six-week mortality rate of approximately 20%. Patients with medium- or large-sized varices can be treated for primary prophylaxis of variceal bleeding using two strategies: non-selective beta-blockers (NSBBs) or endoscopic variceal ligation (EVL). Both treatments are equally effective. Patients with acute variceal bleeding are critically ill patients. The available data suggest that vasoactive drugs, combined with endoscopic therapy and antibiotics, are the best treatment strategy with EVL being the endoscopic procedure of choice. In cases of uncontrolled bleeding, transjugular intrahepatic portosystemic shunt (TIPS) with polytetrafluoroethylene (PTFE)-covered stents are recommended. Approximately 60% of the patients experience rebleeding, with a mortality rate of 30%. Secondary prophylaxis should start on day six following the initial bleeding episode. The combination of NSBBs and EVL is the recommended management, whereas TIPS with PTFE-covered stents are the preferred option in patients who fail endoscopic and pharmacologic treatment. Apart from injection sclerotherapy and EVL, other endoscopic procedures, including tissue adhesives, endoloops, endoscopic clipping and argon plasma coagulation, have been used in the management of esophageal varices. However, their efficacy and safety, compared to standard endoscopic treatment, remain to be further elucidated. There are safety issues accompanying endoscopic techniques with aspiration pneumonia occurring at a rate of approximately 2.5%. In conclusion, future research is needed to improve treatment strategies, including novel endoscopic techniques with better efficacy, lower cost, and fewer adverse events.

    Interventional endoscopy (e.g., bronchoscopy, colonoscopy, laparoscopy, cystoscopy) is a widely performed procedure that involves either diagnosis of suspicious lesions or guidance for minimally invasive surgery in a variety of organs within the body cavity. Endoscopy may also be used to guide the introduction of certain items (e.g., stents) into the body. Endoscopic navigation systems seek to integrate big data with multimodal information (e.g., computed tomography, magnetic resonance images, endoscopic video sequences, ultrasound images, external trackers) relative to the patient's anatomy, control the movement of medical endoscopes and surgical tools, and guide the surgeon's actions during endoscopic interventions. Nevertheless, it remains challenging to realize the next generation of context-aware navigated endoscopy. This review presents a broad survey of various aspects of endoscopic navigation, particularly with respect to the development of of endoscopicnavigation techniques. First, we investigate big data with multimodal information involved in endoscopic navigation. Next, we focus on numerous methodologies used for endoscopic navigation. We then review different endoscopic procedures in clinical applications. Finally, we discuss novel techniques and promising directions for the development of endoscopic navigation. Expected final online publication date for the Annual Review of Biomedical Engineering Volume 20 is June 4, 2018. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

    Endoscopic pertubation of oesophagogustric neoplasms is an established method of palliative treatment. The dislocated plastic prosthesis may be removed with difficulties from the stomach endoscopically. A simple technique for endoscopic removal of the prosthesis is described. The tube can be precisely centred within the oesophageal lumen by use of an intestinal decompression tube and additional guidance by the endoscopic retraction forceps. Thus gross damge of the exophytic tumor tissue with bleeding or perforation sequelae can be avoided. Injury to the patient does not exceed that caused by an ordinary gastroscopy.

    Peroral endoscopic myotomy (POEM) is an innovative, minimally invasive, endoscopic treatment for esophageal achalasia and other esophageal motility disorders, emerged from the natural orifice transluminal endoscopic surgery procedures, and since the first human case performed by Inoue in 2008, showed exciting results in international level, with more than 4000 cases globally up to now. POEM showed superior characteristics than the standard 100-year-old surgical or laparoscopic Heller myotomy (LHM), not only for all types of esophageal achalasia [classical (I), vigorous (II), spastic (III), Chicago Classification], but also for advanced sigmoid type achalasia (S1 and S2), failed LHM, or other esophageal motility disorders (diffuse esophageal spasm, nutcracker esophagus or Jackhammer esophagus). POEM starts with a mucosal incision, followed by submucosal tunnel creation crossing the esophagogastric junction (EGJ) and myotomy. Finally the mucosal entry is closed with endoscopic clip placement. POEM permitted relatively free choice of myotomy length and localization. Although it is technically demanding procedure, POEM can be performed safely and achieves very good control of dysphagia and chest pain. Gastroesophageal reflux is the most common troublesome side effect, and is well controllable with proton pump inhibitors. Furthermore, POEM opened the era of submucosal tunnel endoscopy, with many other applications. Based on the same principles with POEM, in combination with new technological developments, such as endoscopic suturing, peroral endoscopic tumor resection (POET), is safely and effectively applied for challenging submucosal esophageal, EGJ and gastric cardia tumors (submucosal tumors), emerged from muscularis propria. POET showed up to know promising results, however, it is restricted to specialized centers. The present article reviews the recent data of POEM and POET and discussed controversial issues that need further study and future perspectives.

    Full Text Available Using ultrasound data and content of gonadotropin and sex hormones in the blood, the morphological and functional state of the mammary glands, the uterus and the ovaries were studied in women after thyroidectomy and radioiodine therapy, who were taken suppressive therapy with levothyroxine drugs that allows to estimate the hormonal supply of the menstrual cycle and the state of reproductive system. The signs of menstrual cycle disorders and luteal phase deficiency were revealed during the treatment, and dyshormonal hyperplasia of mammary glands was also diagnosed in 82.6 % of cases due to prolonged relative hyperestrogenism and hyperplastic diseases of the uterus and the ovaries, including genital endometriosis, endometrial hyperplasia, uterine myomas, were identified in 80.4 % of cases. A long-term monitoring (every 3 months of thyroid-stimulating hormone, thyroglobulin, thyroglobulin antibodies, follicle-stimulating hormone, luteinizing hormone, prolactin, progesterone, free testosterone, estradiol levels and also the correction of cycle supply using hormonal and non-hormonal methods are needed for this category of patients.

    Endoscopy-associated infection transmission is frequently linked to inadequate reprocessing. Residual organic material and moisture may foster biofilm development inside endoscopes. This study evaluated the effectiveness of endoscope drying and storage methods and assessed associations between retained moisture and contamination. Endoscope reprocessing, drying, and storage practices were assessed at 3 hospitals. Researchers performed visual examinations and tests to detect fluid and contamination on patient-ready endoscopes. Fluid was detected in 22 of 45 (49%) endoscopes. Prevalence of moisture varied significantly by site (5%; 83%; 85%; P < .001). High adenosine triphosphate levels were found in 22% of endoscopes, and microbial growth was detected in 71% of endoscopes. Stenotrophomonas maltophilia, Citrobacter freundii, and Lecanicillium lecanii/Verticillium dahliae were found. Retained fluid was associated with significantly higher adenosine triphosphate levels (P < .01). Reprocessing and drying practices conformed with guidelines at 1 site and were substandard at 2 sites. Damaged endoscopes were in use at all sites. Inadequate reprocessing and insufficient drying contributed to retained fluid and contamination found during this multisite study. More effective methods of endoscope reprocessing, drying, and maintenance are needed to prevent the retention of fluid, organic material, and bioburden that could cause patient illness or injury.

    2010-01-01

    The efficacy of endoscopic screening for esophageal cancer in patients with hypopharyngeal cancer remains controversial and its impact on prognosis has not been adequately discussed. We studied the use of endoscopic screening to detect esophageal cancer in hypopharyngeal cancer patients by analyzing the incidence, stage and prognosis. We included 64 patients with hypopharyngeal cancer who received radical radiotherapy at our institute. Chromoendoscopic esophageal examinations with Lugol dye solution were routinely performed at and after treatment for hypopharyngeal cancer. Twenty-eight esophageal cancers were detected in 28 (41%) patients (18 synchronous and 10 metachronous cancers). Of the 28 cancers, 23 were stage 0 or I cancer and 15 of these were treated with endoscopic resection. Local control was achieved in all of these 23 stage 0 or I cancers. The 5-year overall survival rates with esophageal cancer were 83% in stage 0, 47% in stage I and 0% in stage IIA-IVB. This study showed a strikingly high incidence of esophageal cancer in hypopharyngeal cancer patients. We suppose that the combination of early detection by chromoendoscopic examination and endoscopic resection for associated esophageal cancer in hypopharyngeal cancer patients improve prognosis and maintain quality of life.

    Endoscopic papillary balloon dilatation (EPBD) and endoscopic sphincterotomy (EST) are two common nonsurgical treatments endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis. The aim of this study was to compare the efficacy and safety of EPBD and EST in the treatment for choledocholithiasis, confining the analysis to work reported in the last decade. The rate of overall postoperative complications was chosen as the primary outcome, and 10 other outcomes were secondary outcomes. Relative risk (RR) or Peto odds ratio (OR) were computed as the measures of pooled effects. We planned sensitivity analyses a priori for examining the change in robustness of the sensitivity to excluding studies with some inappropriate objects, technique defects or without full-text acquisition. For complete stone removal, EPBD was similar to EST (95% vs. 96%, P = 0.36) and overall postoperative complications (14.0% vs. 11.7%, P = 0.53). The incidence of post-ERCP cholangitis (2.5% vs. 1.8%, P = 0.40), basket impaction (0.9% vs. 0%, P = 0.16) and perforation (0.0% vs. 0.4%, P = 0.17) were equivalent between EPBD and EST. On the other hand, EPBD caused more post-ERCP pancreatitis (PEP) (9.4% vs. 3.3%, P stone extraction, though it requires more endoscopic mechanical lithotripsy (EML). EPBD may outweigh EST for patients with coagulopathy; however, it may cause more PEP. © 2011 Journal of Gastroenterology and Hepatology Foundation and Blackwell Publishing Asia Pty Ltd.

    Nodularity on the gastric mucosa is occasionally seen in general practice. There is no consensus about the association of nodular gastritis and histological premalignant lesions. This study is designed to investigate the prevalence of histological premalignant lesions in dyspeptic patients with endoscopic nodular gastritis. Consecutive patients with endoscopic nodular gastritis were compared with an age- and sex-matched control group. Endoscopic nodular gastritis was defined as a miliary nodular appearance of the gastric mucosa on endoscopy. Biopsy samples of stomach tissue were examined for the presence of atrophic gastritis, intestinal metaplasia, and dysplasia. The presence of Helicobacter pylori infection was determined by histology. From 5366 evaluated patients, a total of 273 patients with endoscopic nodular gastritis and 1103 participants as control group were enrolled. H. pylori infection was detected in 87.5% of the patients with endoscopic nodular gastritis, whereas 73.8% of the control group were positive for H. pylori (p gastritis were significantly higher than in the control group. Prevalence of atrophic gastritis and complete intestinal metaplasia were also more frequent in patients with endoscopic nodular gastritis than in the control group. Dysplasia, incomplete intestinal metaplasia and H. pylori infection are significantly more frequent in patients with endoscopic nodular gastritis. Although further studies are needed before a clear conclusion can be reached, we suggest that endoscopic nodular gastritis might serve as a premalignant lesion and could be biopsied in all patients for the possibility of histological premalignancy, in addition to H. pylori infection.

    Transtympanic access to the round window membrane (RWM) for drug delivery is in the focus of otology and has stimulated development of various endoscopes. These endoscopes are tasked to enable best visualization at a low diameter and to offer a working channel for various instruments. The specific aspect of sterilization is a major issue especially in regard to the diameter of the endoscope with its integrated working channel. We evaluated a new multi-purpose modular semi-rigid optical fiber endoscope (10,000 pixel resolution) for minimal invasive middle ear endoscopy focusing on access to the RWM and micro instruments in 12 cadaver specimens. Microscopic visualization was compared to endoscopy. With the modular mini ear endoscope (MMEE) we were able to visualize the RWM in 3 specimens directly and in 8 specimens after removal of a mucous membrane using micro instruments. A bony overhang prevented visualization of the RWM in one case. The endoscope enabled minimal invasive RWM access initially in a higher number of cases compared to microscope investigation. The designed MMEE is suited to access transtympanic the round window membrane even in situations of an obstructed round window niche. The modular concept of the endoscope is attractive for different types of indications, various instruments and with regard to the aspects of sterilization. Experiences in humans are the next necessary step to define the possible role of this endoscope in otology.

    2004-01-01

    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

    Several reports have been published in relation to complications, sometimes fatal, associated to endoscopic ventriculocisternostomy (EVC). The objective of this study was to determine the range of complications using this surgical technique in a series of 108 patients. A retrospective and descriptive study was performed on 108 hydrocephalic patients: 76 children and 32 adults. All of them presented various forms of obstructive hydrocephalus. In a total of 108 patients, 114 EVC were performed. The follow-up period ranged between 6 months and 10 years (mean 6.8 years). Age of patients ranged from 6 days to 75 years old (mean 18 years). Aqueductal stenosis was the most common aetiology, with 62 patients (57.4%). Significant complications occurred in 10 patients (9.2%). During the course of the study, the complication rate dropped significantly. No patient died because of the procedure (mortality 0%). We applied the Endoscopic Third Ventriculostomy Success Score (ETVSS) developed by Kulkarni and collaborators to our series to know if this score could be useful in predicting ETV results. Like all minimally-invasive techniques, there is a steep learning curve for EVC. Correct patient selection and surgeon experience (which means not only familiarity with endoscopic techniques but also the performance of a minimum number of surgeries per year) are very important to avoid complications. The ETV Success Score devised closely approximates the predicted probability of ETV success. Copyright © 2014 Sociedad Española de Neurocirugía. Published by Elsevier España. All rights reserved.

    Full Text Available Background: Limited spatial nasal cavity in children, make pediatric dacryocystorhinostomy (DCR a difficult surgical procedure. We apply a limited approach to pediatric DCR and follow them for their consequences. Materials and Methods: An experimental study was done in pediatric DCR with limited approach (age < 14-year-old. After written consent, with general anesthesia, with nasal endoscopic surgery, lacrimal bone is exposed and extruded. In contrast with routine procedure, ascending process of maxillary sinus reserve; and marsupialization and wide exposure to lacrimal sac was done only by lacrimal bone defect; and cannulation preserve with temporary silicone tube. Results: Between 2006 and 2012, 16 pediatric DCR was done by a unique surgeon in 2 otorhinolaryngologic centers. Before surgery 14 (87.5% had epiphora, 3 (18.8% had eye discharge, and 3 (18.8% had eye sticky eye. Two (12.5% had history of facial trauma, and 10 (62.5% had congenital nasolacrimal duct insufficiency. Five (31.3% had history of dacryocystitis. Patients were followed for 17 ± 9 months. Silicone tube stayed for 4 ± 2.5 months. We could follow 7 patients and minimal improvement or need to revision surgery considered as technical failure. After surgery, 3 patients had no epiphora with complete improvement; 2 had very good improvement with confidence of the patients and parents; 2 cases had unsuccessful surgery in our patients, who needs to another surgery. One of them had several probing and surgery before our endoscopic DCR. Conclusions: Limited approach in endoscopic DCR of pediatrics can be done in noncomplicated patients, with minimal manipulation, more confidence, and acceptable results.

  3. Endoscopic management of pancreatic duct injury by endoscopic stent placement: a case report and literature review

    Full Text Available Abstract Recently, the diagnostic evaluation of pancreatic injury has improved dramatically. On the other hand, it is occasionally difficult to diagnose pancreatic injury, because there are no specific signs, symptoms, or laboratory findings. Radiological imaging also often fails to identify pancreatic injury in the acute phase. Delayed diagnosis results in significant morbidity and mortality. Most cases of pancreatic injury with suspicion or pancreatic duct disruption require surgery. Endoscopic retrograde cholangiopancreatography is one of the most accurate modalities for ductal evaluation and therapy and might enable one to avoid unnecessary surgery. We describe endoscopic management of pancreatic duct injury by endoscopic stent placement. A 45-year-old woman was admitted after a traffic accident. A computed tomography scan showed pancreatic parenchyma disruption at the pancreatic head. Endoscopic retrograde cholangiopancreatography demonstrated disruption of the pancreatic duct with extravasation into the peripancreatic fluid collection. A 5-French endoscopic nasopancreatic drainage (ENPD tube was placed. Her symptoms dramatically improved. ENPD tube was exchanged for a 5-French 5-cm pancreatic stent. Subsequent follow-up CT revealed remarkable improvement. On the 26th day, the patient was discharged from the hospital without symptoms or complications. In this report, a pancreatic stent may lead to rapid clinical improvement and enable surgery to be avoided. On the other hand, the reported complications of long-term follow-up make the role of stenting uncertain. Thus, close attention should be paid to stenting management in the follow-up period. A pancreatic stent is useful for pancreatic ductal injury. If pancreatic ductal injury is managed appropriately, a pancreatic stent may improve the clinical condition, and also prevent unnecessary surgery.

    Functional endoscopic sinus surgery is a common procedure performed within otolaryngology, but it carries potential for significant life-changing complications. It is therefore essential that trainees undergo adequate training. The European Working Time Directive has led to reduced operating time for the trainee surgeon. With variable access and the cost implications associated with cadaveric specimens, simulation can be an invaluable educational resource in surgical training. The current literature regarding the various simulation methodologies that have been used in functional endoscopic sinus surgery training is discussed. A literature search was conducted using the key words 'nasal', 'nasal polyps', 'endoscope', 'education and simulation', 'endoscopic sinus surgery' and 'training'. Twelve articles were identified; of these, eight trialled the use of simulators, two utilised ovine models and two used task trainers. Simulation has shown benefit in functional endoscopic sinus surgery training; however, a robust platform accessible to ENT trainees is lacking.

    Historically, neoplasia of the duodenal papilla has been managed surgically, which may be associated with substantial morbidity and mortality. In the absence of invasive cancer, even lesions with extensive lateral duodenal wall involvement, or limited intraductal extension may be cured endoscopically with a superior safety profile. Endoscopic papillectomy is associated with greater risks of adverse events such as bleeding than resection elsewhere in the gastrointestinal tract. Additionally site-specific complications such as pancreatitis exist. A structured approach to lesion assessment, adherence to technical aspects of resection, endoscopic management of complications and post-resection surveillance is required. Advances have been made in all facets of endoscopic papillary resection since its introduction in the 1980s; extending the boundaries of endoscopic cure, optimizing outcomes and enhancing patient safety. These will be the focus of the present review. © 2015 Japan Gastroenterological Endoscopy Society.

    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.

    2010-02-01

    Endoscopic electronic medical record systems (EEMRs) are now increasingly utilized in many endoscopy centers. Modern EEMRs not only support endoscopy report generation, but often include features such as practice management tools, image and video clip management, inventory management, e-faxes to referring physicians, and database support to measure quality and patient outcomes. There are many existing software vendors offering EEMRs, and choosing a software vendor can be time consuming and confusing. The goal of this article is inform the readers about current functionalities available in modern EEMR and provide them with a framework necessary to find an EEMR that is best fit for their practice.

  12. Image acquisition in laparoscopic and endoscopic surgery

    1995-04-01

    Laparoscopic and endoscopic surgery rely uniquely on high quality display of acquired images, but a multitude of problems plague the researcher who attempts to reproduce such images for educational purposes. Some of these are intrinsic limitations of current laparoscopic/endoscopic visualization systems, while others are artifacts solely of the process used to acquire and reproduce such images. Whatever the genesis of these problems, a glance at current literature will reveal the extent to which endoscopy suffers from an inability to reproduce what the surgeon sees during a procedure. The major intrinsic limitation to the acquisition of high-quality still images from laparoscopic procedures lies in the inability to couple directly a camera to the laparoscope. While many systems have this capability, this is useful mostly for otolaryngologists, who do not maintain a sterile field around their scopes. For procedures in which a sterile field must be maintained, one trial method has been to use a beam splitter to send light both to the still camera and the digital video camera. This is no solution, however, since this results in low quality still images as well as a degradation of the image that the surgeon must use to operate, something no surgeon tolerates lightly. Researchers thus must currently rely on other methods for producing images from a laparoscopic procedure. Most manufacturers provide an optional slide or print maker that provides a hardcopy output from the processed composite video signal. The results achieved from such devices are marginal, to say the least. This leaves only one avenue for possible image production, the videotape record of an endoscopic or laparoscopic operation. Video frame grabbing is at least a problem to which industry has applied considerable time and effort to solving. Our own experience with computerized enhancement of videotape frames has been very promising. Computer enhancement allows the researcher to correct several of the

    Helicobacter (H) pylori infection has been considered the most important cause of gastritis, dyspepsia, and gastroduodenal ulcer. Radioiodine can be accumulated in the remaining thyroid tissue, salivary gland, and stomach. We investigated if the high radiation induced by radioiodine in the stomach after high dose radioiodine therapy (HD-RIT) is effective in the eradication of H. pylori infection. One hundred ninety nine patients (M:F=33:166, age 46.7±12.3 years) who had HD-RIT (dose 159.1±25.9 mCi, range 120-250 mCi) after thyroidectomy due to well differentiated thyroid cancer were enrolled. To detect H. pylori infection, the urea breath tests (UBT) were performed at 1 hour before HD-RIT and at 4 weeks after HD-RIT. The results of UBT were classified as positive (≥50 dpm) or negative (<50 dpm), and analyzed its values. Of 199 patients, 103 (51.8%) patients had positive UBT before HD-RIT. Of these, 80 patients had follow-up UBT after HD-RIT. Among them, 76 (95.0%) patients had persistent positive UBT and only 4 (5.0%) patients were changed negative UBT. Among 76 patients with persistent positive UBT, 26 (34.2%) patients had increased the values of follow-up UBT, 49 (64.5%) had decreased them, and 1 (1.3%) had shown the same value. The different values of UBT between before and after HD-RIT were 62±66.1 dpm in increased one of follow-up UBT, and 153.3±157.1 dpm in decreased one of follow-up UBT. We conclude that the radiation induced by HD-RIT is ineffective in the eradication of H. pylori infection. However, it could be influential the degree or distribution of H. pylori infection

    The objective of this study was to assess the cost-effectiveness of antithyroid drug (ATD) therapy vs. radioiodine therapy (RIT) vs. subtotal thyroidectomy (STT) by calculating expected lifelong cost and utility based on Graves' disease patients' responses to questionnaires using a decision-tree sensitivity analysis and relevant variables. The decision-tree sensitivity analysis to determine expected lifelong cost and utility in Graves' disease patients was designed on the basis of the 4 competing strategies consisting of: (1) ATD therapy plus RIT strategy, (2) ATD therapy plus STT strategy, (3) low-fixed-dose (185 MBq) RIT alone strategy, and (4) high-fixed-dose (370 MBq) RIT alone strategy. One-way sensitivity analysis was designed in the ATD therapy plus RIT strategy, for replacement with RIT in place of ATD, ranging from a 1% incidence of ATD side effects to 30%. The low-fixed-dose RIT alone strategy was least costly, and the high-fixed-dose RIT alone strategy most costly. The lifelong utility of high-fixed-dose RIT alone strategy with a 5% rate of discounting was highest (lifelong utility for 30 years: 15.2/patient), and the utility of the ATD plus RIT strategy with 1% side effects of the ATD was lowest (14.1/patient). The cost-effectiveness ratio was lowest (yen 5 008/utility) in a low-fixed-dose RIT alone strategy. In conclusion, a low-fixed-dose RIT alone strategy is preferred treatments in view of cost-effectiveness ratio, and RIT should be used more widely in Japan. (author)

    2012-01-01

    Further development of advanced therapeutic endoscopic techniques and natural orifice translumenal endoscopic surgery (NOTES) requires a powerful flexible endoscopic multitasking platform. Medline search was performed to identify literature relating to flexible endoscopic multitasking platform from year 2004-2011 using keywords: Flexible endoscopic multitasking platform, NOTES, Instrumentation, Endoscopic robotic surgery, and specific names of various endoscopic multitasking platforms. Key articles from articles references were reviewed. Flexible multitasking platforms can be classified as either mechanical or robotic. Purely mechanical systems include the dual channel endoscope (DCE) (Olympus), R-Scope (Olympus), the EndoSamurai (Olympus), the ANUBIScope (Karl-Storz), Incisionless Operating Platform (IOP) (USGI), and DDES system (Boston Scientific). Robotic systems include the MASTER system (Nanyang University, Singapore) and the Viacath (Hansen Medical). The DCE, the R-Scope, the EndoSamurai and the ANUBIScope have integrated visual function and instrument manipulation function. The IOP and DDES systems rely on the conventional flexible endoscope for visualization, and instrument manipulation is integrated through the use of a flexible, often lockable, multichannel access device. The advantage of the access device concept is that it allows optics and instrument dissociation. Due to the anatomical constrains of the pharynx, systems are designed to have a diameter of less than 20 mm. All systems are controlled by traction cable system actuated either by hand or by robotic machinery. In a flexible system, this method of actuation inevitably leads to significant hysteresis. This problem will be accentuated with a long endoscope such as that required in performing colonic procedures. Systems often require multiple operators. To date, the DCE, the R-Scope, the IOP, and the Viacath system have data published relating to their application in human. Alternative forms of

    The effect of the systemic lidocaine on postoperative recovery has not been definitively investigated despite its analgesic efficacy after surgery. The aim of this randomized, double-blinded, controlled study was to evaluate the effect of intravenously administered lidocaine on the quality of recovery and on acute and chronic postoperative pain after robot-assisted thyroidectomy. Ninety patients who were undergoing robotic thyroidectomy were randomly assigned to the lidocaine or the control groups. The patients received 2 mg/kg of lidocaine followed by continuous infusions of 3 mg/kg/h of lidocaine (Group L) or the same volume of 0.9% normal saline (Group C) intravenously during anesthesia. The acute pain profiles and the quality of recovery, which was assessed using the quality of recovery-40 questionnaire (QoR-40), were evaluated for 2 days postoperatively. Chronic postsurgical pain (CPSP) and sensory disturbances at the surgical sites were evaluated 3 months after surgery. The QoR-40 and pain scores that were assessed during the 2 days that followed surgery were largely comparable between the groups. However, CPSP was more prevalent in the Group C than in the Group L (16/43 vs. 6/41; p = 0.025). The tactile sensory score 3 months after the operation was significantly greater in the Group L than in the Group C (7 vs. 5; p = 0.001). Systemic lidocaine administration was associated with reductions in CPSP and sensory impairment after robot-assisted thyroidectomy although it was not able to reduce acute postsurgical pain or improve the quality of recovery.

    Rat pituitary hormones (LH, TSH, GH, FSH and PRL) were located in polyacrylamide gels after the separation of rat pituitary homogenate with the aid of disc electrophoresis. Furthermore, the incorporation of 3 H-glucosamine and 14 C-leucine into various protein fractions of incubation media and pituitaries incubated for 6 h in vitro, homogenized and then subjected to disc electrophoresis was measured in six groups of rats: 1. control; 2. two weeks after thyroidectomy (Tx); 3.-6. two weeks after thyroidectomy and injected 20 μg L-thyroxine (T 4 ) i.p. per animal at 6, 12, 24 and 48 h before sacrifice, respectively. A decrease of 14 C-leucine incorporation into GH and PRL after thyroidectomy was found which was improved by T 4 treatment. Moreover, an increase of 3 H-glucosamine and 14 C-leucine incorporation into TSH zone and origin zone was observed, the former presumably representing the extracted TSH and the latter consisting of unextracted portion of TSH, other hormones and unidentified proteins. Such increase was significantly less after T 4 treatment. Finally, changes of radioimmunoassayable LH, TSH, GH, FSH and PRL in pituitaries and sera of analogous groups of rats, but consisting of other animals were measured. The content of TSH in the pituitary slightly increased after Tx, but increased further after T 4 treatment. In contrast, the content of all other hormones in the pituitary decreased after Tx, while T 4 treatment resulted in a stepwise increase. In plasma, a significant decrease of GH and PRL after Tx was found with no remarkable changes after T 4 treatment. The level of LH and FSH was unchanged, while that of TSH increased significantly after Tx and sharply decreased to the original level already 6 h after the injection of T 4 . (author)

  20. Total versus near-total thyroidectomy in Graves’ disease and their outcome on postoperative transient hypoparathyroidism: study protocol for a randomized controlled trial?

    Full Text Available Abstract Background Graves’ disease is an independent risk factor for transient postoperative hypoparathyroidism. Besides the disease itself, preparation techniques are influential. Transient postoperative hypoparathyroidism has severe consequences for patients’ physical and psychological state. It can be life threatening during the acute phase and may impair patients’ health, psyche and quality of life thereafter. For the surgical therapy of Graves’ disease, total thyroidectomy is recommended according to the national S2-guideline. The evidence- based on a metaanalysis- is criticized by the Cochrane diagnostic review commentary for substantial methodological deficits. Two randomized controlled trials lead to the hypothesis that a near-total resection with bilateral remnants of ≤ 1g on each side compared to total thyroidectomy will significantly reduce the occurrence of transient postoperative hypoparathyroidism with equal therapeutic safety. Methods/Design Patients with Graves’ disease indicated for definite surgery are eligible for the trial. Trial-specific exclusion criteria are: conservative treatment, malignancy, previous thyroid surgery and coincident hypoparathyroidism. The trial is created for therapeutic purpose through process innovation. It is designed as a prospective randomized controlled patient and observer blinded multicentered trial in a parallel design including an active comparator and an intervention group. The intervention addresses the surgical procedure: near-total thyroidectomy leaving bilateral remnants of ≤ 1g on each side in the intervention group and total thyroidectomy in the control group. The occurrence of transient postoperative hypoparathyroidism is defined as primary endpoint. Secondary endpoints are: reoperations due to bleeding, recurrent laryngeal nerve palsy, permanent hypoparathyroidism, recurrent disease, changes of endocrine orbitopathy and quality of life within a one-year follow-up period

    Hungry bone syndrome is a well-established cause of postoperative hypocalcemia in thyrotoxicosis. To date, the incidence of hungry bone syndrome after total thyroidectomy is unclear. This prospective study examined the incidence of postthyroidectomy hungry bone syndrome and its correlation with preoperative bone mineral density. Forty thyrotoxic subjects (Group A; age: mean ± SD; 36.5 ± 9.8 years) and 40 euthyroid controls with benign thyroid nodules (Group B) undergoing total thyroidectomy were evaluated for preoperative bone mineral density and serum calcium, magnesium, phosphorus, parathyroid hormone, alkaline phosphatase, and 25-Hydroxy Vitamin D serially. At least 3 parathyroid glands were preserved. Both groups were age and sex matched. Thyrotoxic subjects had higher postoperative hypocalcemia (82.5% vs controls 22.5%, 95% confidence interval 37.9 to 75.4), low preoperative bone mineral density and raised alkaline phosphatase (each, P = .001). Among thyrotoxic subjects experiencing hypocalcemia (n = 33), 39.4% (13/33) exhibited hungry bone syndrome (characterized by simultaneous fall in serum calcium, magnesium, and phosphorus), 18.1% (6/33) had hypoparathyroidism and 12% had hypomagnesemia. Hypocalcemic subjects exhibiting hungry bone syndrome displayed further decreased preoperative bone mineral density in the spine (0.875 ± 0.138 vs 1.024 ± 0.149 g/cm 2 , P = .004) and low serum magnesium 72-hour postsurgery (0.57 ± 0.23 vs 0.88 ± 0.25 mmol/L, P = .013) than those not exhibiting hungry bone syndrome. Postoperative serum calcium correlated with preoperative bone mineral density in the spine (P = .013). In group B subjects experiencing hypocalcemia (n = 9), none exhibited hungry bone syndrome but 77.78% (7/9) had hypoparathyroidism. All but one was eucalcemic after 6 months. Hungry bone syndrome occurs exclusively in thyrotoxic subjects and constitutes the major cause of postoperative hypocalcemia

    Full Text Available Background: Posterior endoscopic discectomy is an established method for treatment of lumbar disc herniation. Many studies have not been reported in literature for lumbar discectomy by Destandau Endospine System. We report a series of 300 patients operated for lumbar dissectomy by Destandau Endospine system. Materials and Methods: A total of 300 patients suffering from lumbar disc herniations were operated between January 2002 and December 2008. All patients were operated as day care procedure. Technique comprised localization of symptomatic level followed by insertion of an endospine system devise through a 15 mm skin and fascial incision. Endoscopic discectomy is then carried out by conventional micro disc surgery instruments by minimal invasive route. The results were evaluated by Macnab′s criteria after a minimum followup of 12 months and maximum up to 24 months. Results: Based on modified Macnab′s criteria, 90% patients had excellent to good, 8% had fair, and 2% had poor results. The complications observed were discitis and dural tear in five patients each and nerve root injury in two patients. 90% patients were able to return to light and sedentary work with an average delay of 3 weeks and normal physical activities after 2 months. Conclusion: Edoscopic discectomy provides a safe and minimal access corridor for lumbar discectomy. The technique also allows early postoperative mobilization and faster return to work.

    Chronic obstructive pulmonary disease (COPD) is characterized by two entities, the more airway-predominant type (''bronchitis'') on the one hand, and emphysema-predominant type on the other. Imaging via high-resolution computed tomography plays an important role in phenotyping COPD. For patients with advanced lung emphysema, new endoscopic lung volume reduction therapies (ELVR) have been developed. Proper selection of suitable patients requires thin-section reconstruction of volumetric CT image data sets also in coronal and sagittal orientation are required. In the current manuscript we will describe emphysema subtypes (centrilobular, paraseptal, panlobular), options for quantifying emphysema and this importance of regional distribution (homogeneous or heterogeneous, target area) as this is crucial for patient selection. Analysis of the interlobular fissures is obligatory despite the lack of standardization, as incomplete fissures indicate collateral ventilation (CV) via parenchymal bridges, which is an important criterion in choosing endoscopic methods of LVR. Every radiologist should be familiar with modern LVR therapies such as valves and coils, and furthermore should know what a lung doctor expects from radiologic evaluation (before and after ELVR). Finally we present a checklist as a quick reference for all steps concerning imaging for ELVR.

    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.

    To assess whether transcanal endoscopic access to the basal turn of the cochlea for cochlear implantation is appropriate. Case series study. We reviewed 100 consecutive computed tomographic studies of the sinuses and temporal bone in our institution. We excluded studies that demonstrated evidence of congenital anomalies, chronic ear disease, or inadequate visualization of the cochlea. On axial sections, the angles of the basal turn of the cochlea and of the ear canal in reference to the sagittal plane were recorded as a function of age. Eighty-four studies were included and 16 were excluded. There was significant variability in the relationship between the ear canal and the basal turn of the cochlea in reference to the sagittal plane. A clear majority of images demonstrated the basal turn of the cochlea to align with a more posterior angle than that of the ear canal. The trajectory provided by posterior tympanotomy aligns more favorably with the basal turn of the cochlea than transcanal access. Endoscopic technique, primarily an ear canal intervention, may not be useful in cochlear implant surgery. 4.

    Full Text Available To circumvent the disadvantages of endoscopic dacryocystorhinostomy such as small rhinostomy size, high failure rate and expensive equipment, we hereby introduce a modified technique of non-endoscopic mechanical endonasal dacryocystorhinostomy (NE-MEDCR. Surgery is performed under general anesthesia with local decongestion of the nasal mucosa. A 20-gauge vitrectomy light probe is introduced through the upper canaliculus until it touches the bony medial wall of the lacrimal sac. While directly viewing the transilluminated target area, a nasal speculum with a fiber optic light carrier is inserted. An incision is made vertically or in a curvilinear fashion on the nasal mucosa in the lacrimal sac down to the bone using a Freer periosteum elevator. Approximately 1 to 1.5 cm of nasal mucosa is removed with Blakesley forceps. Using a lacrimal punch, the thick bone of the frontal process of the maxilla is removed and the inferior half of the sac is uncovered. The lacrimal sac is tented into the surgical site with the light probe and its medial wall is incised using a 3.2 mm keratome and then excised using the Blakesley forceps. The procedure is completed by silicone intubation. The NE-MEDCR technique does not require expensive instrumentation and is feasible in any standard ophthalmic surgical setting.

    The introduction of endoscopical surgery has among other things influenced technical developments in surgery. Owing to digitalisation, major progress will be made in imaging and in the sophisticated technology sometimes called robotics. Digital storage makes the results of imaging diagnostics (e.g. the results of radiological examination) suitable for transmission via video conference systems for telediagnostic purposes. The availability of digital video technique renders possible the processing, storage and retrieval of moving images as well. During endoscopical operations use may be made of a robot arm which replaces the camera man. The arm does not grow tired and provides a stable image. The surgeon himself can operate or address the arm and it can remember fixed image positions to which it can return if ordered to do so. The next step is to carry out surgical manipulations via a robot arm. This may make operations more patient-friendly. A robot arm can also have remote control: telerobotics.

In one day prior to operation to the patient after bowel preparation the colonoscopy is carried out. In the planned point near tumor on antimesentery edge the submucous infiltration of marking solution (Micky Sharpz blue tattoo pigment, UK is made. The volume of entered solution of 1–3 ml. In only 5 months of use of a technique preoperative marking to 14 patients with small (the size of 1–3 cm malignant tumors of the left colon is performed.Results. The tattoo mark was well visualized by during operation at 13 of 14 patients. In all cases we recorded no complications. Time of operation with preoperative marking averaged 108 min, that is significantly less in comparison with average time of operation with an intra-operative colonoscopy – 155 min (р < 0.001.Conclusions. The first experience of preoperative endoscopic marking of non palpable small tumors of a colon is encouraging. Performance of a technique wasn't accompanied by complications and allowed to reduce significantly time of operation and to simplify conditions of performance of operation.

    The Roux-en-Y gastric bypass (RYGB) is the therapy of choice in bariatric surgery. Sleeve gastrectomy and gastric banding are showing higher rates of treatment failure, reducing obesity-associated morbidity and body weight insufficiently. Moreover, gastroesophageal reflux disease (GERD) can occur refractory to medication. Therefore, a laparoscopic conversion to RYGB can be reasonable as long as specific conditions are fulfilled.Endoscopic procedures are currently being applied to revise bariatric procedures. Therapy failure following RYGB occurs in up to 20 % of cases. Transoral outlet reduction is the minimally invasive method of choice to reduce gastrojejunal anastomosis of the alimentary limb. The diameter of a gastric sleeve can be unwantedly enlarged as well; that can be reduced by placement of a longitudinal full-thickness suture.Severe hypoglycemic episodes can be present in patients following RYGB. Hypoglycemic episodes have to be diagnosed first and can be treated conventionally. Alternatively, a laparoscopic approach according to Branco-Zorron can be used for non-responders. Hypoglycemic episodes can thus be prevented and body weight reduction can be assured.Conversional and endoscopic procedures can be used in patients with treatment failure following bariatric surgery. Note that non-invasive approaches should have been applied intensively before a revisional procedure is performed.

    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.

    Omohyoid muscle syndrome (OMS) (not omohyoid syndrome) is a rare clinical condition that has a characteristic feature of a protruding lateral neck mass during swallowing. The use of endoscopic surgery on the neck is now pretty well established for thyroid and parathyroid glands. Patients with OMS usually undergo simple surgical transection of the omohyoid muscle. The procedure leaves operative scars on the neck, and most patients worry about the cosmetic problems. We report here the first use of an endoscopic procedure instead of traditional surgery for treatment of OMS. We present a rare case of a 26-year-old Chinese man who noted a protruding mass involving the right side of his neck during the past 10 years. OMS was diagnosed. Laparoscopic simple transection of the omohyoid muscle by an ultrasonically activated scalpel was performed. After laparoscopic transection of the omohyoid muscle, the neck mass completely disappeared during swallowing, and there were no operative scars on the neck. To our knowledge, this is the first report of laparoscopy for treatment of OMS. We believe that the laparoscopic procedure is made acceptable for this unusual disease because of the cosmetic result.

    Endoscopic technology has been developed to facilitate imagery for use during diagnostic and therapeutic phases of periodontal care. The purpose of this study was to compare the level of subgingival calculus detection using a periodontal endoscope with that of conventional tactile explorer in periodontitis subjects. A convenience sample of 26 subjects with moderate periodontitis in at least 2 quadrants was recruited from the University of Minnesota School of Dentistry to undergo quadrant scaling and root planing. One quadrant from each subject was randomized for tactile calculus detection alone and the other quadrant for tactile detection plus the Perioscope ™ (Perioscopy Inc., Oakland, Cali). A calculus index on a 0 to 3 score was performed at baseline and at 2 post-scaling and root planing visits. Sites where calculus was detected at visit 1 were retreated. T-tests were used to determine within-subject differences between Perioscope™ and tactile measures, and changes in measures between visits. Significantly more calculus was detected using the Perioscope™ vs. tactile explorer for all 3 subject visits (pcalculus detection from baseline to visit 1 were statistically significant for both the Perioscope™ and tactile quadrants (pcalculus detection from visit 1 to visit 2 was only significant for the Perioscope™ quadrant (pcalculus at this visit. It was concluded that the addition of a visual component to calculus detection via the Perioscope™ was most helpful in the re-evaluation phase of periodontal therapy.

    Full Text Available Endoscopic third ventriculostomy (ETV is a routine and safe procedure for therapy of obstructive hydrocephalus. The aim of our study is to evaluate ETV success rate in therapy of obstructive hydrocephalus in pediatric patients formerly treated by ventriculoperitoneal (V-P shunt implantation. From 2001 till 2011, ETV was performed in 42 patients with former V-P drainage implantation. In all patients, the obstruction in aqueduct or outflow parts of the fourth ventricle was proved by MRI. During the surgery, V-P shunt was clipped and ETV was performed. In case of favourable clinical state and MRI functional stoma, the V-P shunt has been removed 3 months after ETV. These patients with V-P shunt possible removing were evaluated as successful. In our group of 42 patients we were successful in 29 patients (69%. There were two serious complications (4.7%—one patient died 2.5 years and one patient died 1 year after surgery in consequence of delayed ETV failure. ETV is the method of choice in obstructive hydrocephalus even in patients with former V-P shunt implantation. In case of acute or scheduled V-P shunt surgical revision, MRI is feasible, and if ventricular system obstruction is diagnosed, the hydrocephalus may be solved endoscopically.

    Limited spatial nasal cavity in children, make pediatric dacryocystorhinostomy (DCR) a difficult surgical procedure. We apply a limited approach to pediatric DCR and follow them for their consequences. An experimental study was done in pediatric DCR with limited approach (age bone is exposed and extruded. In contrast with routine procedure, ascending process of maxillary sinus reserve; and marsupialization and wide exposure to lacrimal sac was done only by lacrimal bone defect; and cannulation preserve with temporary silicone tube. Between 2006 and 2012, 16 pediatric DCR was done by a unique surgeon in 2 otorhinolaryngologic centers. Before surgery 14 (87.5%) had epiphora, 3 (18.8%) had eye discharge, and 3 (18.8%) had eye sticky eye. Two (12.5%) had history of facial trauma, and 10 (62.5%) had congenital nasolacrimal duct insufficiency. Five (31.3%) had history of dacryocystitis. Patients were followed for 17 ± 9 months. Silicone tube stayed for 4 ± 2.5 months. We could follow 7 patients and minimal improvement or need to revision surgery considered as technical failure. After surgery, 3 patients had no epiphora with complete improvement; 2 had very good improvement with confidence of the patients and parents; 2 cases had unsuccessful surgery in our patients, who needs to another surgery. One of them had several probing and surgery before our endoscopic DCR. Limited approach in endoscopic DCR of pediatrics can be done in noncomplicated patients, with minimal manipulation, more confidence, and acceptable results.

    Full Text Available Endoscopic submucosal dissection (ESD is accepted as a minimally invasive treatment for colorectal cancer. However, due to technical difficulties and an increased rate of complications, ESD is not widely used in the colorectum. In some cases, endoscopic treatment alone is insufficient for disease control, and laparoscopic surgery is required. The combination of laparoscopic surgery and endoscopic resection represents a new frontier in cancer treatment. Recent developments in advanced polypectomy and minimally invasive surgical techniques will enable surgeons and endoscopists to challenge current practice in colorectal cancer treatment. Endoscopic full-thickness resection (EFTR of the colon offers the potential to decrease the postoperative morbidity and mortality associated with segmental colectomy while enhancing the diagnostic yield compared to current endoscopic techniques. However, closure is necessary after EFTR and natural transluminal endoscopic surgery (NOTES. Innovative methods and new devices for EFTR and suturing are being developed and may potentially change traditional paradigms to achieve minimally invasive surgery for colorectal cancer. The present paper aims to discuss the complementary role of ESD and the future development of EFTR. We focus on the possibility of achieving EFTR using the ESD method and closing devices.

  17. Endoscopic Approach for Major Complications of Bariatric Surgery.

    As lifestyle and diet patterns have become westernized in East Asia, the prevalence of obesity has rapidly increased. Bariatric surgeries, such as Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), and laparoscopic adjustable gastric banding (LAGB), are considered the first-line treatment option in patients with severe obesity. However, postoperative complications have increased and the proper management of these complications, including the use of endoscopic procedures, has become important. The most serious complications, such as leaks and fistulas, can be treated with endoscopic stent placement and injection of fibrin glue, and a novel full-thickness closure over-the-scope clip (OTSC) has been used for treatment of postoperative leaks. Stricture at the gastrojejunal (GJ) anastomosis site after RYGB or incisura angularis in SG can be managed using stents or endoscopic balloon dilation. Dilation of the GJ anastomosis or gastric pouch may lead to failure of weight loss, and the use of endoscopic sclerotherapy, novel endoscopic suturing devices, and OTSCs have been attempted. Intragastric migration of the gastric band can be successfully treated using various endoscopic tools. Endoscopy plays a pivotal role in the management of post-bariatric complications, and close cooperation between endoscopists and bariatric surgeons may further increase the success rate of endoscopic procedures.

    To determine the feasibility, advantages, and disadvantages of using a robot for holding and maneuvering the endoscope in transnasal transsphenoidal surgery. The system used in this study was a Stewart Platform based robotic system that was developed by Kocaeli University Department of Mechatronics Engineering for positioning and holding of endoscope. After the first use on an artificial head model, the system was used on six fresh postmortem bodies that were provided by the Morgue Specialization Department of the Forensic Medicine Institute (Istanbul, Turkey). The setup required for robotic system was easy, the time for registration procedure and setup of the robot takes 15 minutes. The resistance was felt on haptic arm in case of contact or friction with adjacent tissues. The adaptation process was shorter with the mouse to manipulate the endoscope. The endoscopic transsphenoidal approach was achieved with the robotic system. The endoscope was guided to the sphenoid ostium with the help of the robotic arm. This robotic system can be used in endoscopic transsphenoidal surgery as an endoscope positioner and holder. The robot is able to change the position easily with the help of an assistant and prevents tremor, and provides a better field of vision for work.

    Endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) have much in common, including their main indications (biliopancreatic disorders), powerful therapeutic capacities and a steep learning curve. Over the years they have evolved from novel diagnostic procedures to interventional therapeutic techniques, but along different paths (different scopes or devices and endoscopists specializing exclusively in one or the other technique). However, EUS has gradually developed into a therapeutic technique that requires skills in the use of ERCP devices and stents, leading some ERCP specialists to explore the therapeutic potential of EUS. The corresponding literature, which has grown exponentially, includes recent experiments on combining the two techniques, which have gradually come to be used in routine care in a number of centers, with positive technical, clinical and financial outcomes. We review EUS and ERCP as individual or combined procedures for managing biliopancreatic disorders. Copyright © 2016 Elsevier España, S.L.U. y AEEH y AEG. All rights reserved.

    Acute subdural hematoma evacuations frequently necessitate large craniotomies with extended operative times and high relative blood loss, which can lead to additional morbidity for the patient. While endoscopic minimally invasive approaches to chronic subdural collections have been successfully demonstrated, this technique has not previously been applied to acute subdural hematomas. The authors report their experience with an 87-year-old patient presenting with a large acute right-sided subdural hematoma successfully evacuated via an endoscopic minimally invasive technique. The operative approach is outlined, and the literature on endoscopic subdural collection evacuation reviewed. Copyright © 2013. Published by Elsevier Ltd.

    Full Text Available Duodenal intramural hematoma (DIH usually occurs in childhood and young adults following blunt abdominal trauma. It may also develop in the presence of coagulation disorders and may rarely be an iatrogenic outcome of endoscopic procedures. Management of DIH is usually a conservative approach. A case of intramural duodenal hematoma that developed following endoscopic epinephrine sclerotherapy and/or argon plasma coagulation and that was nonresponsive to conservative therapy in a patient with chronic renal failure who died from sepsis is being discussed in this report. Clinicians should be aware of such possible complications after endoscopic hemostasis in patients with coagulation disorders.

    1997-01-01

    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

    Full Text Available Introduction Headache is a common complaint that brings patients to multidisciplinary clinics. It is utmost important to have meticulous clinical diagnosis of patients with rhinogenic and non sinusogenic headaches. The diagnosis has become easier with the advent of modern endoscopy and endoscopic sinus surgical techniques. This study aims to investigate the role of some anatomical nasal abnormalities in rhinogenic contact headache and to evaluate response to endoscopic surgery.   Materials and Method A prospective study was conducted at a secondary level regional referral Hospital in the Sultanate of Oman. Patients with long-lasting, frequent, severe headaches not amenable to medical treatment, above 20 years of age were taken into consideration. Routine nasal endoscopy, Computerized tomography scan of the paranasal sinuses, Nasal decongestion and various surgical techniques to correct the anatomical abnormalities were included in our study and results were correlated statistically.   Result There was a male predominance in our study with duration of headache ranging from 2 weeks to 5 years. There was a preponderance of headache in frontal region in our study group. Diagnostic nasal endoscopy and CT scan of PNS revealed Deviated nasal septum / septal spur, concha bullosa, Haller cell, pneumatised uncinate process and agar nasi cells. The overall success rate of the surgery in relieving headaches, measured by the MIDAS- VAS score, was approximately 75 %. The non-parametric Wilcoxon signed rank test, Chi square and paired T tests shows that the following study has rejected the null hypothesis as statistically significant where the P value <0.05.   Discussion Researchers have examined the contact points as a source of rhinogenic / contact headache. Intranasal mucosal contact released substance P, causing pain and headache, Substance P has a potent vasodilator effect. Vasodilatation and perivascular inflammation are the final common pathways in

    Nasal polyposis is often encountered in rhinology practice. Those who fail conservative management, a definitive surgery is essential to achieve sufficient ventilation and drainage of the affected sinuses by using either microdebrider or conventional instruments for functional endoscopic sinus surgery (FESS). A prospective study was conducted on 40 cases of nasal polypi in a tertiary care hospital. 20 cases were operated by conventional endoscopic instruments and 20 using the microdebrider. The study aimed at comparing the intra operative (blood loss, duration of surgery) and post operative results (crusting, scarring, discharge, symptoms, recurrence) between the two groups using Lund-Mackay scoring system and the data was statistically analysed. There was no statistically significant difference in surgical outcome for patients when either conventional endoscopic instruments or microdebrider was used. However, there was a significant symptomatic improvement in cases undergoing microdebrider FESS. Microdebrider assisted polypectomy is precise, relatively bloodless surgery though the precision depends on the surgeon's anatomical knowledge and operative skills. Study substantiates that these instruments are helpful but not a prerequisite for successful outcomes in FESS. The study re-emphasises the utility of the microdebrider to young learning FESS surgeons.

    Full Text Available Background. Patients with metastatic or radioactive iodine refractory papillary thyroid carcinoma (PTC have poor prognosis due to ineffective therapy for this condition beyond surgery and radioactive iodine (RAI or 131I. BRAF mutation occurs in more than 44% of PCT. Tyrosine kinase inhibitors, the most commonly used agents for these patients, have weak BRAF inhibition activity. BRAF inhibitors have demonstrated promising efficacy in relapsed metastatic PCT after standard treatment, though they are not currently approved for this indication. Case Presentation. We present the case of a 48-year-old Hispanic male who initially presented with columnar-cell variant subtype of PTC and positive BRAFV600E mutation. The patient had widespread bulky metastases to lungs, chest wall, brain, and bone. Discussion. Initial use of vemurafenib demonstrated a 42% cytoreduction of targeted pulmonary metastases and facilitated thyroidectomy and RAI treatment. The patient achieved a durable response over 21 months in the setting of widely metastatic disease. Conclusion. Vemurafenib may be effectively used for cytoreduction in patients with bulky metastatic PTC to bridge them to thyroidectomy and RAI treatment.

    Full Text Available To determine the clinicopathological risk factors and reliable biochemical predictors of the development of hypocalcemic symptoms after total thyroidectomy on the basis of serum calcium and intact parathyroid hormone (PTH levels measured 1 hour after surgery, a prospective study was performed on 817 patients who underwent a total thyroidectomy with central compartment node dissection (CCND due to well-differentiated thyroid cancer. We evaluated the correlations between hypocalcemic symptom development and clinicopathological factors. And the predictability for hypocalcemic symptom development of intact PTH cut-offs (<10 pg/mL and <20 pg/mL, resp. according to serum calcium level subgroup was analyzed. Female gender (P<0.001 was the only independent risk factor for hypocalcemic symptom development in multivariate regression analysis. The negative predictive value (NPV of intact PTH, signifying nondevelopment of hypocalcemic symptoms, was higher than the positive predictive value (PPV which signified development of hypocalcemic symptoms. In addition, when we applied the different adoption of the intact PTH cut-off according to serum calcium level, we could obtain more increased NPVs. A female gender and the application of more specific cut-offs for intact PTH according to the serum calcium levels measured 1 hour after surgery may help the patients to be more safely discharged.

    The aim of the present study was to evaluate the role of hypothyroidism as a cause of hyponatremia in a clinical model of iatrogenic acute hypothyroidism due to thyroid hormone withdrawal prior to ablative radioactive iodine (RAI) therapy after total thyroidectomy. The study group consisted of 101 differentiated thyroid cancer (DTC) patients (77 women and 24 men). Plasma concentration of thyroid-stimulating hormone ([TSH]) and sodium ([Na + ]) was evaluated before total thyroidectomy (pre[TSH] and pre[Na + ]) and on the day of RAI therapy (post[TSH] and post[Na + ]). The frequency of hypothyroidism-associated hyponatremia was 4 % (4/101). Pre[Na + ] was significantly higher than post[Na + ] (140.7 ± 1.6 vs 138.7 ± 2.3 mEq/L, p = 0.012). Moreover, a linear correlation was identified between pre[Na + ] and post[Na + ]. Iatrogenic acute hypothyroidism-related hyponatremia is uncommon. However, because of the significant reduction of [Na + ] in the transition from euthyroidism to iatrogenic hypothyroidism, the value of pre[Na + ] should be viewed as a parameter to be considered. Since it acts as an independent risk factor for the development of hyponatremia, patients with a pre[Na + ] close to the lower limit of normal range may deserve a closer monitoring of [Na + ].

  9. Pre-Operative Lugol's Iodine Treatment in the Management of Patients Undergoing Thyroidectomy for Graves' Disease: A Review of the Literature.

    2017-02-01

    To undertake a review of the relevant English literature published on the pre-operative use of Lugol's iodine in the management of patients undergoing thyroidectomy for Graves' disease. We reviewed all relevant papers found through Ovid Medline, PubMed, EMBASE and the American Thyroid Association website. Searches were limited to the English language only. The critical appraisal tool CASP was used to help analyse the papers. Following this, the evidence was ranked using the Harbour and Miller classification of hierarchy. Four papers were deemed appropriate for analysis. The evidence contained within the review is considered weak. The literature available in the public domain regarding the use of iodinated solutions in the pre-operative period for those patients about to undergo thyroidectomy for Graves' disease is scant. Having undertaken an extensive literature review, we are of the opinion that the evidence on which the American Thyroid Association's guidance on the use of preoperative Lugol's iodine is based is tenuous. There appears to be little in the way of sound clinical evidence that post-operative outcomes are any different following a course of Lugol's iodine. Given the lack of robust clinical evidence regarding the clinical need for iodine solution in the pre-operative period, it appears clear that a larger, prospective, randomised controlled trial of all relevant outcomes - clinical and scientific - is required to answer whether or not patient preparation with Lugol's iodine is in fact necessary prior to operative intervention for Graves' disease.

    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.

  13. Per-oral endoscopic myotomy for achalasia.

    Science.gov (United States)

    DeMeester, Steven R

    2017-03-01

    Symptoms in patients with achalasia are produced by outflow obstruction at the level of the lower esophageal sphincter (LES). As a consequence of neural destruction the LES does not undergo normal swallow-induced relaxation. In addition, the esophageal body loses normal peristaltic function and esophageal emptying is on the basis of gravity. All therapies for achalasia are palliative in that normal LES or esophageal body function cannot be restored. The efficacy of any therapy for achalasia is directly related to its ability to reduce the outflow obstruction at the LES. The three main treatment options are pneumatic dilatation, laparoscopic myotomy and partial fundoplication and per-oral endoscopic myotomy or per-oral esophageal myotomy (POEM). Details of the procedures and outcomes will be discussed.

    2016-03-01

    Tears in the gluteus medius and minimus tendons have been recognized as an important cause of recalcitrant greater trochanteric pain syndrome. Because of the frequency of partial-thickness undersurface tears, this relatively unknown pathology is often misdiagnosed and left untreated. Surgery is indicated in case of 4 associated conditions: (i) Failure of conservative treatment with duration of symptoms >6 months; (ii) magnetic resonance imaging showing a tendon tear; (iii) positive ultrasound-guided infiltration test; and (iv) the absence of an evolved fatty degeneration or atrophy of the gluteus medius and minimus muscle. Endoscopic repair of partial or full-thickness tears, with systematic resection of the bony structures implicated in the impingement, and a complete bursectomy appear to give satisfactory results, although these results remain to be confirmed by clinical studies with longer follow-up. The degree of tendon degeneration may compromise the tissue left for reattachment, raising concerns over its healing capacity, durability, and ultimate strength of the repair.

    Tan, Ke; Wang, Bin; Gao, Yuan

    2017-07-01

    Endoscopy imaging is utilized to provide a realistic view about the surfaces of organs inside the human body. Owing to the damp internal environment, these surfaces usually have a glossy appearance showing specular reflections. For many computer vision algorithms, the highlights created by specular reflections may become a significant source of error. In this paper, we present a novel method for restoration of the specular reflection regions from a single image. Specular restoration process starts with generating a substitute specular-free image with RPCA method. Then the specular removed image was obtained by taking the binary weighting template of highlight regions as the weighting for merging the original specular image and the substitute image. The modified template was furthermore discussed for the concealment of artificial effects in the edge of specular regions. Experimental results on the removal of the endoscopic image with specular reflections demonstrate the efficiency of the proposed method comparing to the existing methods.

    2012-01-01

    To demonstrate a comprehensive review of published articles regarding endoscopic ultrasound (EUS)-guided biliary drainage. Review of studies regarding EUS-guided biliary drainage including case reports, case series and previous reviews. EUS-guided hepaticogastrostomy, coledochoduodenostomy and choledoantrostomy are advanced biliary and pancreatic endoscopy procedures, and together make up the echo-guided biliary drainage. Hepaticogastrostomy is indicated in cases of hilar obstruction, while the procedure of choice is the coledochoduodenostomy or choledochoantrostomy in distal lesions. Both procedures must be performed only after unsuccessful ERCPs. The indication of these procedures must be made under a multidisciplinary view while sharing information with the patient or legal guardian. Hepaticogastrostomy and coledochoduodenostomy or choledochoantrostomy are feasible when performed by endoscopists with expertise in biliopancreatic endoscopy. Advanced echo-endoscopy should currently be performed under a rigorous protocol in educational institutions.

    Pescarus, Radu; Shlomovitz, Eran; Swanstrom, Lee L

    2014-01-01

    Per-oral endoscopic myotomy (POEM) is a new minimally invasive endoscopic treatment for achalasia. Since the first modern human cases were published in 2008, around 2,000 cases have been performed worldwide. This technique requires advanced endoscopic skills and a learning curve of at least 20 cases. POEM is highly successful with over 90 % improvement in dysphagia while offering patients the advantage of a low impact endoscopic access. The main long-term complication is gastroesophageal reflux (GER) with an estimated incidence of 35 %, similar to the incidence of GER post-laparoscopic Heller with fundoplication. Although POEM represents a paradigm shift in the treatment of achalasia, more long-term data are clearly needed to further define its role in the treatment algorithm of this rare disease.

    Science.gov (United States)

    Kim, Sang Gyun

    2016-01-01

    Endoscopic resection of early gastric cancer is defined as incomplete when tumor cells are found at the resection margin upon histopathological examination. However, a tumor-positive resection margin does not always indicate residual tumor; it can also be caused by tissue contraction during fixation, by the cautery effect during endoscopic resection, or by incorrect histopathological mapping. Cases of highly suspicious residual tumor require additional endoscopic or surgical resection. For inoperable patients, argon plasma coagulation can be used as an alternative endoscopic treatment. Immediately after the incomplete resection or residual tumor has been confirmed by the pathologist, clinicians should also decide upon any additional treatment to be carried out during the follow-up period.

    2017-01-01

    Full Text Available Squamous cell head and neck carcinoma is frequently associated with dysphagia. An adequate enteral nutrition is the key to successful treatment and rehabilitation of these patients. Percutaneous endoscopic gastrostomy is the preferred route of feeding and nutritional support in head and neck cancer patients with dysphagia. We report a rare case of implantation metastasis of laryngeal cancer following percutaneous endoscopic gastrostomy. Our experience in treating this complication has been described. Percutaneous endoscopic gastrostomy is a less-invasive procedure than open gastrostomy. Percutaneous endoscopic gastrostomy can be accompanied by severe complications such as implantation metastasis at gastrostomy site. Careful monitoring can provide early detection of this complication and early treatment.

    Gastric schwannoma is not so recognized by clinicians as its counterparts. The efficacy of endoscopic resection has not been described yet. Our aim was to assess the efficacy and safety of endoscopic resection in the management of gastric schwannoma. Retrospective data were reviewed from January 2008 to December 2013 in our center. Fourteen patients who had endoscopic resection with the final pathology result of gastric schwannoma were included in the study. Of the 14 patients, there were 12 females and two males. The median age was 59 years (range 32-83). Thirteen tumors (92.9 %) were from the muscularis propria and one located in the submucosa. Endoscopic en bloc resection was achieved in 12 patients (12/14, 85.7 %), including seven cases of endoscopic full-thickness resection (EFTR). The mean resected tumor size was 1.73 ± 1.10 cm (range 0.3-4.0 cm). In one case, endoscopic resection was suspended due to the limited experience of EFTR during the early period of the study. In another case, due to the difficult tumor location (gastric angle) and extraluminal growth pattern, the patient was referred to laparoscopic surgery. In the 12 successful endoscopic resection cases, during the median follow-up time of 4 years (range 17-77 months, one patient lost), no tumor residue, recurrence or metastasis was found. Endoscopic resection is safe and effective in treating gastric schwannoma with excellent long-term outcomes. However, it should be performed with caution because schwannoma is mainly located in the deep muscular layer, which leads to the full-thickness resection of gastric wall.

    Full Text Available The endoscopic examination of a 64-year-old male patient revealed a gastric submucosal tumor in the anterior wall of the gastric antrum. The lesion increased in diameter to 25 mm and was resected completely with endoscopic submucosal dissection (ESD. Histological examination of the submucosal tumor gave a diagnosis of an inflammatory fibroid polyp (IFP. It is suggested that ESD may be an effective and safe therapy for gastric submucosal tumors.

    We report a case of leiomyosarcoma of the distal third of the esophagus in a 51-year-old woman presenting with a six-month history of severe epigastric pain, disphagia and weight loss. The diagnosis, suspected on endoscopic examination, was preoperatively acheived by biopsy and immunohistological stain. Surgical treatment was undertaken with good results. Differentiation between leiomyosarcoma and more common esophageal neoplasm may be difficult if based on radiographic and endoscopic appeara...

    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.

    Five endoscopes equipped with infrared cameras working in the medium infrared range (3-5 μm) are installed on the controlled thermonuclear fusion research device Tore-Supra. These endoscopes aim at monitoring the plasma facing components surface temperature to prevent their overheating. Signals delivered by infrared cameras through endoscopes are analysed and used on the one hand through a real time feedback control loop acting on the heating systems of the plasma to decrease plasma facing components surface temperatures when necessary, on the other hand for physics studies such as determination of the incoming heat flux . To ensure these two roles a very accurate knowledge of the absolute surface temperatures is mandatory. Consequently the infrared endoscopes must be calibrated through a very careful procedure. This means determining their transmission coefficients which is a delicate operation. Methods to calibrate infrared endoscopes during the shutdown period of the Tore-Supra machine will be presented. As they do not allow determining the possible transmittances evolution during operation an in-situ method is presented. It permits the validation of the calibration performed in laboratory as well as the monitoring of their evolution during machine operation. This is possible by the use of the endoscope shutter and a dedicated plasma scenario developed to heat it. Possible improvements of this method are briefly evoked.

    Endoscopic approaches to obesity may help fulfill the unmet need of over half the US adult population who would benefit from therapy for obesity but are not receiving it. Endoluminal approaches have the potential to be more efficacious than antiobesity medications and have a lower risk-cost profile compared with bariatric surgery. This review outlines the current state of primary endoscopic weight loss and metabolic therapies and sheds light on the challenges faced toward making endoscopic bariatric therapies 'ready for prime time'. Endoscopic approaches to obesity are being increasingly modeled on the proposed mechanisms contributing to the benefits of bariatric surgery.Therapies targeted at the stomach induce weight loss with only a proportional benefit to underlying metabolic disorders.Therapies targeting the proximal small bowel appear to modulate various neurohormonal pathways resulting in an improvement in metabolic profile in excess to that accounted for by weight loss itself. Rigorous scientific assessment of endoscopic approaches to obesity is necessary to allow its integration into the treatment algorithm of obesity. The endoscopic armamentarium against obesity continues to evolve with the endoscopist poised to be a key player in the management of this disease. http://links.lww.com/COG/A12.

  18. Endoscope-magnetic tracker calibration via trust region optimization

    2010-02-01

    Minimally invasive surgical techniques and advanced imaging systems are gaining prevalence in modern clinical practice. Using miniaturized magnetic trackers in combination with these procedures can help physicians with the orientation and guidance of instruments in graphical displays, navigation during surgery, 3D reconstruction of anatomy, and other applications. Magnetic trackers are often used in conjunction with other sensors or instruments such as endoscopes and optical trackers. In such applications, complex calibration procedures are required to align the coordinate systems of the different devices in order to produce accurate results. Unfortunately, current calibration procedures developed for augmented reality are cumbersome and unsuitable for repeated use in a clinical setting. This paper presents an efficient automated endoscope-tracker calibration algorithm for clinical applications. The algorithm is based on a state-of-the-art trust region optimization method and requires minimal intervention from the endoscope operator. The only required input is a short video of a calibration grid taken with the endoscope and attached magnetic tracker prior to the procedure. The three stage calibration process uses a traditional camera calibration to determine the intrinsic and extrinsic parameters of the endoscope, and then the endoscope is registered in the tracker's reference frame using a novel linear estimation method and a trust region optimization algorithm. This innovative method eliminates the need for complicated calibration procedures and facilitates the use of magnetic tracking devices in clinical settings.

    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.

    This study aimed to verify whether the approaching time (the time taken to reach the target point from another point, a short distance apart, during point-to-point movement in endoscopic surgery), assessed using the Hiroshima University Endoscopic Surgical Assessment Device (HUESAD), could distinguish the skill level of surgeons. Expert surgeons (who had performed more than 50 endoscopic surgeries) and novice surgeons (who had no experience in performing endoscopic surgery) were tested using the HUESAD. The approaching time, total time, and intermediate time (total time--approaching time) were measured and analyzed using the trajectory of the tip of the instrument. The approaching time and total time were significantly shorter in the expert group than in the novice group (p time did not significantly differ between the groups (p > 0.05). The approaching time, which is a component of the total time, is very mportant in the measurement of the total time to assess endoscopic surgical skills. Further, the approaching time was useful for skill assessment by the HUESAD for evaluating the skill of surgeons performing endoscopic surgery.

    2007-09-01

    To review the current state of natural orifice surgery and examine the concerns, challenges, and opportunities presented by translumenal research. Translumenal endoscopic procedures have been the focus of extensive research. Researchers have reported natural orifice translumenal endoscopic surgery in a swine model in several areas involving the abdominal cavity. Diagnostic procedures have included endoscopic peritoneoscopy, liver biopsy, lymphadenectomy, and abdominal exploration. Several gynecologic procedures including tubal ligation, oophorectomy, and partial hysterectomy have been demonstrated using current commercial endoscopes. Gastrointestinal surgical procedures, including gastrojejunostomy, cholecystectomy, splenectomy, and distal pancreatectomy have been performed successfully via transgastric and/or transcolonic approaches. There have been no studies of natural orifice translumenal endoscopic surgery procedures published in humans. While fundamental questions about the emerging technology have not been scrutinized, limitations of the large animal model will pose a challenge to the development of large randomized trials. While natural orifice translumenal endoscopic surgery may represent a paradigm shift and may offer significant benefits to patients, rigorous testing of the techniques is lacking and current data have been drawn from case series.

    Endoscopic repair of orbital blow-out fractures could become a predictable and efficient treatment alternative to traditional methods. However, maxillary sinus endoscopy provides a complex and disorienting view of the orbital floor. To be a useful and consistent technique for providing access to the orbital floor, specific knowledge of maxillary endoscopic anatomy is required. The purpose of the study was to provide an anatomic description of the orbital floor via the endoscopic approach. Objectives include defining consistent landmarks for use in endoscopic repair of orbital floor fractures. Using 0- and 30-degree rigid endoscopes, 6 fresh cadavers (12 maxillary sinuses) were examined via a standard Caldwell-Luc approach. Computed tomographic scans, plastic molds, and digital images were used to compare observable averages within bony anatomy. Potential bony landmarks were correlated with soft-tissue anatomy in fresh specimens. The maxillary ostium, orbital floor, and lateral ethmoid air cells were visualized, and their structures were described. Observations were made in relation to the anatomy of the orbital floor and maxillary sinus, including fracture pattern and force transmission pathways. An "orbitomaxillary" sinus bony thickening was identified and described for the first time. This study provides the basis for further refinement of surgical technique and opens the door for future clinical trials using endoscopic repair.

    Full Text Available Non Steroidal Anti Inflammatory Drugs (NSAID have been associated with a sudden and sustained rise in the incidence of gastrointestinal ulcer complications. The aim of the study was to reveal the endoscopical abnormalities found in the duodenum & proximal jejunum due to NSAID. Thirty eight patients taking NSAID for their arthritis or rheumatism were included in this study. Gastro-duodeno-jejunoscopy was done with Olympus PCF-10. The endoscopical appearances of NSAID entero gastropathy were evaluated with a scoring system. The NSAID-entero-gastropathy appearances were endoscopically seen as hyperemia, erosion and ulcer. From all patient recruited, 7.9% complaint of diarrhea and 71.1% complaint of dyspepsia. Endoscopically, in the duodenal bulb we found 79% cases of hyperemia, 39.5% cases of erosion and 7.9% cases of ulcer. In the second part (descending part of the duodenum we found 28.9% cases of hyperemia, 15.8% cases of erosion and 2.6% case of ulcer. In the jejunum, we found 7.9% cases of hyperemia, 2.6% case of erosion and no ulcer. It is concluded that the most frequent abnormal endoscopical appearances in NSAID- enteropathy was hyperemia. The most frequent site of NSAID-enteropathy abnormal findings was in the duodenal bulb. (Med J Indones 2005; 14: 225-9Keywords: NSAID-enteropathy, endoscopical appearances.

    Full Text Available Endoscopic examination of the gastrointestinal (GI tract plays a very important role in the diagnosis and follow-up of patients with Crohn's disease (CD and intestinal tuberculosis (TB. The clinical, morphological, and histological features of GI TB and CD are so similar that it becomes difficult to differentiate between these two entities. In geographical regions such as India where both GI TB and CD are prevalent, differential diagnosis between the two is challenging. While there is a lot of similarities between these two disorders, these two can be differentiated from each other with a combination of clinical, endoscopic, histological, radiological, and endoscopic features. The observation of the characteristic lesions at endoscopic examination and the extent of involvement in CD and intestinal TB is an important step in differentiation between these two disorders. While the most important endoscopic characteristics such as involvement of left side of the colon and presence of longitudinal ulcerations and cobblestoning support a diagnosis of CD, predominant involvement of ileocecal region and transverse ulcers support the diagnosis of intestinal TB. In this review, we have described the usefulness and limitations of endoscopic modalities in the diagnosis and differentiation of intestinal TB and CD.

    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 extent of thyroidectomy for low-risk well-differentiated thyroid cancer (WDTC) remains controversial. Historically, total thyroidectomy (TT) has been recommended for WDTC ≥1 cm in size. However, recent National Comprehensive Cancer Network and American Thyroid Association guidelines recognize unilateral thyroid lobectomy as a viable alternative for 1-4 cm cancers due to their otherwise favorable prognosis, with TT remaining the preferred option for tumors with unfavorable pathological characteristics. This study sought to determine how often a completion TT would be recommended based on these guidelines if lobectomy was initially performed in patients with 1-4 cm WDTC without preoperatively known risk factors. Patients who underwent thyroidectomy for 1-4 cm WDTC (January 2000 to January 2010) were retrospectively reviewed. Patients with preoperatively known high-risk characteristics, including gross extrathyroidal extension (ETE) on preoperative imaging, clinically apparent lymph node metastases, distant metastases, history of radiation, and positive family history, were excluded. The pathology specimens from the cancer-containing lobe were evaluated for features that would lead to a recommendation for TT based on current guidelines, including aggressive histology, vascular invasion, microscopic ETE, positive margins, and any positive lymph nodes within the specimen. Of 1000 consecutive patients operated for WDTC, 287 would have been eligible for lobectomy as the initial operation. The mean age in this cohort was 45 years, and 80% were women. Aggressive tall-cell variant histology was found in one patient (0.5%), angio-invasion in 34 (12%), ETE in 48 (17%), positive margins in 51 (18%), and positive lymph nodes in 49 (18%) patients. Completion TT would have been recommended in 122/287 (43%) patients. Even in those with 1-2 cm cancers, completion TT would have been recommended in 52/143 (36%) patients. Nearly half of the patients with 1-4 cm WDTC

    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.

    Review of the English orthopaedic literature reveals no prior report of endoscopic repair of rectus abdominis tears and/or prepubic aponeurosis detachment. This technical report describes endoscopic reattachment of an avulsed prepubic aponeurosis and endoscopic repair of a vertical rectus abdominis tear immediately after endoscopic pubic symphysectomy for coexistent recalcitrant osteitis pubis as a single-stage outpatient surgery. Endoscopic rectus abdominis repair and prepubic aponeurosis repair are feasible surgeries that complement endoscopic pubic symphysectomy for patients with concurrent osteitis pubis and expand the less invasive options for patients with athletic pubalgia.

    Reoperative thyroid surgery is associated with a higher morbidity and has traditionally been done in conventional open approach. This study aimed to evaluate the safety and effectiveness of endoscopic areola approach for reoperative thyroid surgery. A retrospective study was conducted in 46 patients undergoing reoperative thyroid surgery with endoscopic areola approach (endoscopic group) and 70 patients with conventional open approach (open group). Perioperative and follow-up outcomes were compared between the two groups. Baseline characteristics were comparable between the two groups. Except for two cases of the endoscopic group intraoperatively converted to open surgery, all the other surgery was successfully completed. No significant difference was found between two groups concerning operation time, drainage volume, drainage time and postoperative hospital stay (all P > 0.05). Estimated blood loss was more in the open group than the endoscopic group (P = 0.000). Although not statistically significant, the overall complication rate was less in the endoscopic group than in the open group (21.7 vs. 37.1 %, P = 0.079). Of these complications, transient hypocalcemia was the most common (endoscopic group, 17.4 %; open group, 21.4 %; P = 0.594). One patient of the endoscopic group and 7 patients of the open group suffered from transient recurrent laryngeal nerve (RLN) paralysis (P = 0.210). Moreover, 2 patients of open group experienced permanent RLN paralysis. During the follow-up period (range 1-6 years), no recurrent case was encountered, but the endoscopic group had a higher cosmetic score (9.0 ± 0.9 vs. 5.9 ± 0.9, P = 0.000). In high-volume centers, with strict operation indication, sufficient preoperative evaluation and careful surgical maneuvers, endoscopic areola approach is a safe and effective method for reoperative thyroid surgery, allowing to provide a better cosmetic result and reduce intraoperative blood loss compared with open

    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

    Transforaminal Percutaneous Endoscopic Discectomy (TPED) is a minimally invasive technique mainly used for the treatment of lumbar disc herniation from a lateral approach. Performed under local anesthesia, TPED has been proven to be a safe and effective technique which has been also associated with shorter rehabilitation period, reduced blood loss, trauma, and scar tissue compared to conventional procedures. However, the procedure should be performed by a spine surgeon experienced in the specific technique and capable of recognizing or avoiding various challenging conditions. In this review, pitfalls that a novice surgeon has to be mindful of, are reported and analyzed.

    The general surgeon has been practising thyroid surgery for over 70 years and has done it well. The exposure to short-lived isotopes of iodine is a risk factor in the development of thyroid cancer. Therefore, the objective of this study was two-fold. Firstly, to reemphasize the importance of the general surgeon in thyroid surgery. Secondly, to examine the possible links between the incidence of thyroid cancer in Belgium and the radiation exposure caused by the Chernobyl cloud. To carry out this study we retrospectively analysed the files of 1207 patients who had undergone thyroid surgery between 1978 and 2004 in a hospital in the south of Belgium; all operations were performed by the same surgeon. The study showed that surgery of the thyroid is carried out safely and effectively by the general surgeon. The study included 18 haemorrhagic complications (1.5%) of which 9 needed reintubation and further emergency surgery; 8 recurrent laryngeal nerve damage (0.66%); 73 cases of transitory symptomatic hypocalcaemia requiring the administration of oral calcium (6%) and 15 cases of postoperative infection of the surgical wound (1.24%). This level of complication proves that accurate, well-regulated procedures always carried out by the same surgeon make it possible to reduce the number of complications relating to thyroidectomy. The study also shows us that the question of the link with the Chernobyl accident remains open. Several facts may be emphasized. The annual average rate for cancer went from 1 before the nuclear plant accident of Chernobyl to 3.6 after April 1986. There was also an "increase" of thyroid surgical operations in 1999 (13 years after the accident). In this particular year there were 79, while the usual annual average is 46 surgery cases per year. Of these 79 surgical cases, there were 16 cancers (20.25%), while the percentage of cancer cases for the entire study was 6% of patients. Before 1986, of the 286 cases operated on, 8 were cancer, which

    Prosthetic materials wrapped around a portion of the stomach have been used to provide gastric restriction in bariatric surgery for many years. Intraluminal erosion of adjustable and nonadjustable gastric bands typically occurs many years after placement and results in various symptoms. Endoscopic management of gastric band erosion has been described and allows for optimal patient outcomes. We will describe our methods and experience with endoscopic management of intraluminal gastric band erosions after bariatric procedures. University hospital in the United States. A retrospective review of our bariatric surgery database identified patients undergoing removal of gastric bands. A chart review was then undertaken to confirm erosion of prosthetic material into the gastrointestinal tract. Baseline characteristics, operative reports, and follow-up data were analyzed. Sixteen patients were identified with an eroded gastric band: 11 after banded gastric bypass, 3 after laparoscopic adjustable gastric band (LAGB), and 2 after vertical banded gastroplasty. All patients were successfully treated with endoscopic removal of the prosthetic materials using either endoscopic scissors or ligation of the banding material with off-label use of a mechanical lithotripter device. Complications included a postoperative gastrointestinal bleed requiring repeat endoscopy, 1 patient with asymptomatic pneumoperitoneum requiring observation, and 1 with seroma at the site of LAGB port removal. Endoscopic management of intraluminal prosthetic erosion after gastric banded bariatric procedures can be safe and effective and should be considered when treating this complication. Erosion of the prosthetic materials inside the gastric lumen allows for potential endoscopic removal without free intraabdominal perforation. Endoscopic devices designed for dividing eroded LAGBs may help standardize and increase utilization of this approach. Copyright © 2017 American Society for Bariatric Surgery

    The advent of endoscopic techniques changed surgery in many regards. This paper intends to describe an overview about technologies to facilitate endoscopic surgery. The systems described have been developed for the use in general surgery, but an easy application also in other fields of endoscopic surgery seems realistic. The introduction of system technology and robotic technology enables today to design a highly ergonomic solo-surgery platform. This consists of a system of devices for endoscopic surgery (HF, light source, etc...) with which the surgeon interacts directly, positioning systems for optic and instruments that the surgeon drives as the likes without assistance, and a chair to increase the comfort of the surgeon during surgery. The system of endoscopic devices named OREST (Dornier, München) designed already in 1992 opened the way to a number of systems available today that allow to the surgeon a direct control of the instrumentation. A considerable step ahead in endoscopic technology is the introduction of robotic technology to design assisting systems for solo-surgery and microsurgical instrument manipulators. Results of a number of experimental trials on combinations of different positioning devices are presented and commented. A further step in the employment of robotic technology is the design of "master-slave manipulators" to provide the surgeon with additional degrees of freedom of instrumentation. In 1996 a first prototype of an endoscopic manipulator system, named ARTEMIS, designed in cooperation with the Research Center in Karlsruhe, could be used in experimental applications. Clinical use of the system, however, will require further development of the arm mechanics and the control system. The combination with the implementation of telecommunication technology will open new frontiers, such as teleconsulting, teleassistance and telemanipulation.

    The learning curve for endonasal endoscopic and neuroendoscopic port surgery is long and often associated with an increase in complication rates as surgeons gain experience. We present an animal model for laboratory training aiming to encourage the young generation of neurosurgeons to pursue proficiency in endoscopic neurosurgical techniques. 20 Wistar rats were used as models. The animals were introduced into a physical trainer with multiple ports to carry out fully endoscopic microsurgical procedures. The vertical and horizontal dimensions of the paired ports (simulated nostrils) were: 35×20 mm, 35×15 mm, 25×15 mm, and 25×10 mm. 2 additional single 11.5 mm endoscopic ports were added. Surgical depth varied as desired between 8 and 15 cm. The cervical and abdominal regions were the focus of the endoscopic microsurgical exercises. The different endoscopic neurosurgical techniques were effectively trained at the millimetric dimension. Levels of progressive surgical difficulty depending upon the endoneurosurgical skills set needed for a particular surgical exercise were distinguished. LEVEL 1 is soft-tissue microdissection (exposure of cervical muscular plane and retroperitoneal space); LEVEL 2 is soft-tissue-vascular and vascular-capsule microdissection (aorto-cava exposure, carotid sheath opening, external jugular vein isolation); LEVEL 3 is artery-nerve microdissection (carotid-vagal separation); LEVEL 4 is artery-vein microdissection (aorto-cava separation); LEVEL 5 is vascular repair and microsuturing (aortic rupture), which verified the lack of current proper instrumentation. The animal training model presented here has the potential to shorten the length of the learning curve in endonasal endoscopic and neuroendoscopic port surgery and reduce the incidence of training-related surgical complications. © Georg Thieme Verlag KG Stuttgart · New York.

    Although all types of endoscopic procedures harbor risk of aspiration, little is understood about risk factors for aspiration pneumonia developing after endoscopic hemostasis. The present study aimed to identify risk factors for aspiration pneumonia after endoscopic hemostasis. Charts from consecutive patients with upper gastrointestinal bleeding that had been treated by endoscopic hemostasis at a single center between January 2004 and January 2015 were retrospectively reviewed. Patient information and clinical characteristics including cause of hemorrhage, established prognostic scales, laboratory data, comorbidities, medications, duration of endoscopic hemostasis, vital signs, sedative use, and the main operator during the procedure were compared between patients who developed aspiration pneumonia and those who did not. Aspiration pneumonia developed in 24 (4.8%) of 504 patients after endoscopic hemostasis. Endotracheal intubation was required for three of them, and one died of the complication. Multivariate analysis revealed that age >75 years (odds ratio (OR) 4.4; 95% confidence interval (CI) 1.5-13.6; p = 0.0073), procedural duration >30 min (OR 5.6; 95% CI 1.9-18.2; p = 0.0023), hemodialysis (OR 3.6; 95% CI 1.2-11; p = 0.024), and a history of stroke (OR 3.8; 95% CI 1-14; p = 0.041) were independent risk factors for developing aspiration pneumonia. Specific risk factors for aspiration pneumonia after endoscopic hemostasis were identified. Endoscopists should carefully consider aspiration pneumonia when managing older patients who are on hemodialysis, have a history of stroke, and undergo a longer procedure.

    Endoscopic vacuum therapy is a novel option for the management of esophageal leaks. This study compares endoscopic vacuum therapy versus placement of covered stents for anastomotic leaks after esophagectomy. N = 45 consecutive patients with anastomotic leaks following esophagectomy (including patients referred to our center from other hospitals for complication management) were managed by endoscopic therapy at our institution from January 2009 to February 2015. Outcomes of stent and endoscopic vacuum therapy were analyzed retrospectively. Thirty patients received endoscopic stent placement and 15 endoscopic vacuum therapy. In the stent group, seven patients were switched to endoscopic vacuum and four to surgery. Classified by type of initial endoscopic therapy, the success rate (anastomotic healing, patient recovered) was higher for endoscopic vacuum therapy (endoscopic vacuum 93.3%, stent 63.3 %; p = 0.038). Classified by final endoscopic therapy (after switches in therapy), success rates were 86.4 and 60.9% (p = 0.091), respectively. There was no difference observed in mortality, duration of therapy, and length of hospital stay between the study groups. Endoscopic vacuum therapy might be more effective than endoscopic stent placement in the management of esophageal anastomotic leaks.

    Objective: To study the changes of serum lipid profile after withdrawl of levo-thyroxine replacement for 4 weeks in patient with radical thyroidectomy for cancer. Methods: Serum thyroid hormones (FT 3 , FT 4 , sTSH, with RIA) levels and lipid profile (Total cholesterol, triglycerides, LDL, HDL, apolipoprotein A-I, apolipoprotein B and Lp (a), with biochemistry) were determined in 46 patients with thyroid carcinoma after operation both during and after 4 weeks' withdrawl of levo-thyroxine replacement treatment. Results: Serum FT 3 , FT 4 levels decreased significantly and serum sTSH, TC, TG, LDL, apo-B, Lp (a) levels increased significantly after 4 weeks' withdrawl of levo-thyroxine replacement (vs during treatment, P 0.05). Conclusion: Hyperlipidaemia did develop in the hypothyroid patients after withdrawl of levo-thyroxine replacement but the degree of which did not not necessarily correlate with the increment of sTSH levels.

    Endoscopic ultrasonography (EUS) is widely used to evaluate pancreaticobiliary diseases, especially pancreatic masses. EUS has a good ability to detect pancreatic masses, but it is not sufficient for the differential diagnosis of various types of lesions. In order to address the limitations of EUS, new techniques have been developed to improve the characterization of the lesions detected by EUS. EUS-guided fine needle aspiration (EUS-FNA) has been used for diagnosing pancreatic tumors. In order to improve the histological diagnostic yield, a EUS-FNA needle with a core trap has recently been developed. Contrast-enhanced harmonic EUS is a new imaging modality that uses an ultrasonographic contrast agent to visualize blood flow in fine vessels. This technique is useful in the diagnosis of pancreatic solid lesions and in confirming the presence of vascularity in mural nodules for cystic lesions. EUS elastography analyzes several different variables to measure tissue elasticity, color patterns, and strain ratio, using analytical techniques such as hue-histogram analysis, and artificial neural networks, which are useful for the diagnosis of chronic pancreatitis and pancreatic cancer.

    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.

    Clinical statistics has shown a stable prevalence of bladder cancer in recent years, which by far remains among the most common types of malignancy in the USA. With smoking as the most well-established risk factor, bladder cancer is the fourth most common cancer occurrences in male population [1]. In the year of 2014, an estimated 74,690 new cases are expected to occur with estimated 15,580 deaths. Bladder cancer often refers to transitional cell carcinoma (TCC) as it originates primarily from the epithelial cell layer (i.e., urothelium) of the bladder. Unlike prostate-specific antigen (PSA) for prostate cancer screening, there is currently no effective screening technique approved or recommended for the population at average risk [2-5]. As a result, hematuria (i.e., blood in the urine) is often the first clinical symptom of bladder cancer. Fortunately, urinary bladder is more accessible than prostate glands endoscopically; thus cytology following white-light cystoscopy has been the gold standard for current clinical detection of bladder cancer. This is important because bladder cancer if diagnosed prior to muscle invasion (e.g., superficial or at cancer patients.

  4. Chromaticity based smoke removal in endoscopic images

    In minimally invasive surgery, image quality is a critical pre-requisite to ensure a surgeons ability to perform a procedure. In endoscopic procedures, image quality can deteriorate for a number of reasons such as fogging due to the temperature gradient after intra-corporeal insertion, lack of focus and due to smoke generated when using electro-cautery to dissect tissues without bleeding. In this paper we investigate the use of vision processing techniques to remove surgical smoke and improve the clarity of the image. We model the image formation process by introducing a haze medium to account for the degradation of visibility. For simplicity and computational efficiency we use an adapted dark-channel prior method combined with histogram equalization to remove smoke artifacts to recover the radiance image and enhance the contrast and brightness of the final result. Our initial results on images from robotic assisted procedures are promising and show that the proposed approach may be used to enhance image quality during surgery without additional suction devices. In addition, the processing pipeline may be used as an important part of a robust surgical vision pipeline that can continue working in the presence of smoke.

    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.

    Resection of the hippocampus is the standard of care for medically intractable epilepsy in patients with mesial temporal sclerosis. Although temporal craniotomy in this setting is highly successful, the procedure carries certain immutable risks and may be associated with cognitive deficits related to cortical and white matter disruption. Alternative surgical approaches may reduce some of these risks by preserving the lateral temporal lobe. This study examined the feasibility of transorbital endoscopic amygdalohippocampectomy (TEA) as an alternative to open craniotomy in cadaveric specimens. TEA dissections were performed in 4 hemispheres from 2 injected cadaveric specimens fixed in alcohol. Quantitative predictions of the limits of exposure based on predissection imaging were compared with intradissection measurements. The extent of resection and angles of exposure during the dissection and on postdissection imaging were recorded. These measurements were validated with MRI studies from 10 epilepsy patients undergoing standard surgical evaluations. The transorbital approach permitted direct access to the mesial temporal structures through the lateral orbital wall. Up to 97% of the hippocampal formation was resected with no brain retraction and minimal (mean 6.0 ± 1.4 mm) globe displacement. Lateral temporal lobe white matter tracts were preserved. TEA permits hippocampectomy comparable to standard surgical approaches without disrupting the lateral temporal cortex or white matter. This novel approach is feasible in cadaveric specimens and warrants clinical investigation in carefully selected cases.

    Objective: To assess the quality and patient satisfaction in Endoscopy Unit of Shifa International Hospital. Study Design: Cross-sectional survey. Place and Duration of Study: Division of Gastroenterology, Shifa International Hospital, Islamabad, Pakistan, from July 2011 to January 2012. Methodology: Quality and patient satisfaction after the endoscopic procedure was assessed using a modified GHAA-9 questionnaire. Data was analyzed using SPSS version 16. Results: A total of 1028 patients were included with a mean age of 45 A+- 14.21 years. Out of all the procedures, 670 (65.17%) were gastroscopies, 181 (17.60%) were flexible sigmoidoscopies and 177 (17.21%) were colonoscopies. The maximum unsatisfactory responses were on the waiting time before the procedure (13.13 %), followed by unsatisfactory explanation of the procedure and answers to questions (7.58%). Overall, unsatisfied impression was 4.86%. The problem rate was 6.22%. Conclusion: The quality of procedures and level of satisfaction of patients undergoing a gastroscopy or colonoscopy was generally good. The factors that influence the satisfaction of these patients are related to communication between doctor and patient, doctor's manner and waiting time for the procedure. Feedback information in an endoscopy unit may be useful in improving standards, including the performance of endoscopists. (author)

  8. Bilateral Truncal Ligation of the Inferior Thyroid Artery during Bilateral Subtotal Thyroidectomy Causes a Decrease in Parathormone without Clinically Manifest Hypoparathyroidism: A Randomized Clinical Trial.

    Bilateral truncal ligation (BTL) of the inferior thyroid artery (ITA) is frequently used during subtotal thyroidectomy to reduce the risk of post-operative bleeding as well as to reduce the blood loss intra-operatively. However, its effect on parathyroid function has not been evaluated in relation to age, residual and resected thyroid volume. A total of 83 patients were randomized to receive non-BTL or BTL. After bilateral resection, the residual thyroid tissue on each side was measured by intra-operative ultrasonography. Laboratory and clinical examinations were performed the day before operation, intra-operatively and on post-operative days 2 and 5. The primary outcome measure was the difference in intact parathormone (PTHi) on post-operative day 5. Secondary outcomes were laboratory-diagnosed hypocalcaemia or hypoparathyroidism and clinically manifest hypoparathyroidism, respectively. PTHi on post-operative day 5 was significantly lower in the BTL group (29.4 vs. 34.7 ng/l in the non-BTL group, p = 0.033), especially in 61- to 80-year-old patients (0 vs. -7.91 ng/l, p = 0.029). The biggest decline in PTHi was found in the BTL group (-14.067 ng/l PTH, p = 0.018) with a residual thyroid volume of 0.5-1.9 ml. There were two cases of asymptomatic hypoparathyroidism in each group (5.1 vs. 4.8%, respectively, p = 1.000). The only case of clinically manifest hypoparathyroidism was in a BTL group patient aged 64 years (2.4%, p = 1.000). BTL of the ITA during subtotal thyroidectomy causes a larger decrease in PTH but does not lead to a significantly higher rate of clinically manifest hypoparathyroidism.

    Carpal tunnel syndrome (CTS) is the most common compressive neuropathy of the upper extremity. It is caused by increased pressure on the median nerve between the transverse carpal ligament and the carpal bones. Surgical treatment consists of the release of the nerve by cutting the transverse carpal ligament. This can be done either with an open approach or endoscopically. To assess the effectiveness and safety of the endoscopic techniques of carpal tunnel release compared to any other surgical intervention for the treatment of CTS. More specifically, to evaluate the relative impact of endoscopic techniques in relieving symptoms, producing functional recovery (return to work and return to daily activities) and reducing complication rates. This review fully incorporates the results of searches conducted up to 5 November 2012, when we searched the Cochrane Neuromuscular Disease Group Specialized Register, CENTRAL, MEDLINE and EMBASE. There were no language restrictions. We reviewed the reference lists of relevant articles and contacted trial authors. We also searched trial registers for ongoing trials. We performed a preliminary screen of searches to November 2013 to identify any additional recent publications. We included any randomised controlled trials (RCTs) and quasi-RCTs comparing endoscopic carpal tunnel release (ECTR) with any other surgical intervention for the treatment of CTS. We used standard methodological procedures expected by the Cochrane Collaboration. Twenty-eight studies (2586 hands) were included. Twenty-three studies compared ECTR to standard open carpal tunnel release (OCTR), five studies compared ECTR with OCTR using a modified incision, and two studies used a three-arm design to compare ECTR, standard OCTR and modified OCTR.At short-term follow-up (three months or less), only one study provided data for overall improvement. We found no differences on the Symptom Severity Scale (SSS) (scale zero to five) (five studies, standardised mean

    2012-08-01

    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.

    Full Text Available Abstract Background The instrument channels of gastrointestinal (GI endoscopes may be heavily contaminated with bacteria even after high-level disinfection (HLD. The British Society of Gastroenterology guidelines emphasize the benefits of manually brushing endoscope channels and using automated endoscope reprocessors (AERs for disinfecting endoscopes. In this study, we aimed to assess the effectiveness of decontamination using reprocessors after HLD by comparing the cultured samples obtained from biopsy channels (BCs of GI endoscopes and the internal surfaces of AERs. Methods We conducted a 5-year prospective study. Every month random consecutive sampling was carried out after a complete reprocessing cycle; 420 rinse and swabs samples were collected from BCs and internal surface of AERs, respectively. Of the 420 rinse samples collected from the BC of the GI endoscopes, 300 were obtained from the BCs of gastroscopes and 120 from BCs of colonoscopes. Samples were collected by flushing the BCs with sterile distilled water, and swabbing the residual water from the AERs after reprocessing. These samples were cultured to detect the presence of aerobic and anaerobic bacteria and mycobacteria. Results The number of culture-positive samples obtained from BCs (13.6%, 57/420 was significantly higher than that obtained from AERs (1.7%, 7/420. In addition, the number of culture-positive samples obtained from the BCs of gastroscopes (10.7%, 32/300 and colonoscopes (20.8%, 25/120 were significantly higher than that obtained from AER reprocess to gastroscopes (2.0%, 6/300 and AER reprocess to colonoscopes (0.8%, 1/120. Conclusions Culturing rinse samples obtained from BCs provides a better indication of the effectiveness of the decontamination of GI endoscopes after HLD than culturing the swab samples obtained from the inner surfaces of AERs as the swab samples only indicate whether the AERs are free from microbial contamination or not.

    Endoscopic drainage of pancreatic acute and chronic pseudocysts and pancreatic necrosectomy have been shown to be beneficial for critically ill patients, with complete endoscopic resolution rates of around 80%. Our purpose was to describe an improved endoscopic technique used to treat pancreatic necrosis. Case report. University hospital. Two patients with large retroperitoneal necroses were treated with percutaneous transgastric retroperitoneal flushing tubes and a percutaneous transgastric jejunal feeding tube by standard percutaneous endoscopic gastrostomy access in addition to endoscopic necrosectomy. Intensive percutaneous transgastric flushing in combination with percutaneous normocaloric enteral nutrition and repeated endoscopic necrosectomy led to excellent outcomes in both patients. Small number of patients. The "double percutaneous endoscopic gastrostomy" approach for simultaneous transgastric drainage and normocaloric enteral nutrition in severe cases of pancreatic necroses is safe and effective. It could be a promising improvement to endoscopic transgastric treatment options in necrotizing pancreatitis.
