    Wiesław Pesta


    Full Text Available In spite of medical science development and initiation of new technologies in minimally invasive surgery, treatmentof advanced chronic venous insufficiency at the 5th and 6th degree of CEAP classification is still a great clinical challenge.In case of no satisfactory results of non-surgical treatment of recurrent venous ulcers, scientists search for alternativetherapeutic methods which could be more effective and lasting. Subfascial endoscopic perforator vein surgery(SEPS as a method of reducing venous pressure in the superficial venous system could provide healing of the recurrentvenous ulcer. In this study we present a review of contemporary opinions about the place and significance of subfascialendoscopic perforator vein surgery as a treatment of advanced chronic venous insufficiency.

  4. Endoscopic closure of septal perforations. (United States)

    Alobid, Isam


    The management of septal perforations is a challenge for the surgeon. A wide variety of surgical techniques have been described, with different approaches. There is no scientific evidence to support a particular approach. The objective of this review is to present a practical guide on the technique of choice for each case of septal perforation. Inspection of the nasal mucosa, the size of the perforation, the location and especially the osteo-cartilaginous support, are the pillars of a successful surgery. For the sliding or rotating flaps of the mucosa of the septum it is essential to know in advance if the elevation of the mucopericondrio or mucoperiosteo of the septum is possible, otherwise the use of these flaps would not be indicated. The flaps of the lateral wall or nasal floor are the alternative. The pericranial flap may be indicated in total or near total perforations. The remnant of the nasal septum and status of osteo-cartilaginous support are the determining factors in the management of septal perforations. Each case should be evaluated individually and the approach chosen according to the size and location of the perforation, mucosal quality, personal history, previous surgery and the experience of the surgeon.

  7. Esophageal Perforation due to Transesophageal Echocardiogram: New Endoscopic Clip Treatment

    Directory of Open Access Journals (Sweden)

    John Robotis


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

    Gastric perforation is one of the most serious complications that can occur during endoscopic submucosal dissection (ESD). In terms of the treatment of such perforations, we previously reported that perforations immediately observed and successfully closed with endoclips during endoscopic resection could be managed conservatively. We now report the first case in our medical facility of a gastric perforation during ESD that was ineffectively treated conservatively even after successful endoscopic closure. In December 2006, we performed ESD on a recurrent early gastric cancer in an 81-year-old man with a medical history of laparotomy for cholelithiasis. A perforation occurred during ESD that was immediately observed and successfully closed with endoclips so that ESD could be continued resulting in an en-bloc resection. Intensive conservative management was conducted following ESD, however, an endoscopic examination five days after ESD revealed dehiscence of the perforation requiring an emergency laparotomy.

  11. Management and associated factors of delayed perforation after gastric endoscopic submucosal dissection (United States)

    Suzuki, Haruhisa; Oda, Ichiro; Sekiguchi, Masau; Abe, Seiichiro; Nonaka, Satoru; Yoshinaga, Shigetaka; Nakajima, Takeshi; Saito, Yutaka


    AIM: To identify the actual clinical management and associated factors of delayed perforation after gastric endoscopic submucosal dissection (ESD). METHODS: A total of 4943 early gastric cancer (EGC) patients underwent ESD at our hospital between January 1999 and June 2012. We retrospectively assessed the actual management of delayed perforation. In addition, to determine the factors associated with delayed perforation, after excluding 123 EGC patients with perforations that occurred during the ESD procedure, we analyzed the following clinicopathological factors among the remaining 4820 EGC patients by comparing the ESD cases with delayed perforation and the ESD cases without perforation: age, sex, chronological periods, clinical indications for ESD, status of the stomach, location, gastric circumference, tumor size, invasion depth, presence/absence of ulceration, histological type, type of resection, and procedure time. RESULTS: Delayed perforation occurred in 7 (0.1%) cases. The median time until the occurrence of delayed perforation was 11 h (range, 6-172 h). Three (43%) of the 7 cases required emergency surgery, while four were conservatively managed without surgical intervention. Among the 4 cases with conservative management, 2 were successfully managed endoscopically using the endoloop-endoclip technique. The median hospital stay was 18 d (range, 15-45 d). There were no delayed perforation-related deaths. Based on a multivariate analysis, gastric tube cases (OR = 11.0; 95%CI: 1.7-73.3; P = 0.013) were significantly associated with delayed perforation. CONCLUSION: Endoscopists must be aware of not only the identified factors associated with delayed perforation, but also how to treat this complication effectively and promptly. PMID:26640340

  12. Endoscopic Management of Colonic Perforation due to Ventriculoperitoneal Shunt: Case Report and Literature Review

    Directory of Open Access Journals (Sweden)

    Ana Rita Alves


    Full Text Available The authors report the case of a 41-year-old woman with a colonic perforation due to a ventriculoperitoneal shunt (VPS catheter. Left-sided colonic perforation was diagnosed by abdominal computed tomography 28 years after shunt placement, following acute meningitis caused by Escherichia coli. The proximal end of the VPS was exteriorized and it was decided to remove the distal end by colonoscopy. After pulling out the catheter with a polypectomy snare, it broke at the site where it was entering the colon, leaving a small perforation in the colonic wall which was closed with 2 endoclips. The endoluminal fragment of the catheter, being 20 cm in length, was removed through the rectum. The patient is asymptomatic at the 12-month follow-up. A review of the literature regarding 9 endoscopically managed cases of digestive tract perforation caused by VPS is presented.

  13. A novel method for endoscopic perforation management by using abdominal exploration and full-thickness sutured closure. (United States)

    Kumar, Nitin; Thompson, Christopher C


    Perforation of the GI tract during endoscopy can result in significant morbidity and mortality. Early recognition and immediate management of endoscopic perforation are essential to optimize outcome. Larger perforations, defects with complex geometry, and those complicated by leakage of luminal contents have traditionally required surgical management. To assess the feasibility of a new method for managing complex perforations that incorporates abdominal exploration and endoscopic sutured closure. Case series. Tertiary care center. Two patients with large, complicated perforations and peritoneal contamination. Endoscopic exploration of abdomen with angiocatheter placement under direct visualization, management of leaked luminal contents, and full-thickness sutured defect closure. Endoscopic abdominal exploration through the perforation site allowed safe placement of an angiocatheter for management of pneumoperitoneum, inspection for injury that may warrant surgical management, and removal of leaked luminal contents. Endoscopic sutured closure allowed safe and robust perforation management. Repair of gastrojejunal anastomotic perforation required 2 sutures and 63 minutes. Repair of gastric perforation required 4 sutures and 48 minutes. Patients had successful endoscopic defect closure confirmed by an upper GI series and were discharged 1 day later. Report of a new method in 2 patients performed at tertiary care center. We demonstrate successful management of complex perforations with peritoneal contamination by incorporating endoscopic exploration and sutured closure with standard treatment measures. Traditional practice would have directed these patients to surgical management, which introduces additional morbidity and cost. A means for safe and broad implementation of these techniques should be evaluated. Copyright © 2014 American Society for Gastrointestinal Endoscopy. Published by Mosby, Inc. All rights reserved.

  14. Endoscopic observation of different repair patterns in human traumatic tympanic membrane perforations. (United States)

    Huang, Peng; Zhang, Shujun; Gong, Xinhong; Wang, Xuesong; Lou, Zi-Han


    In the last decade, there has been an increasing use of biomaterial patches in the regeneration of traumatic tympanic membrane perforations. The major advantages of biomaterial patches are to provisionally restore the physiological function of the middle ear, thereby immediately improving ear symptoms, and act as a scaffold for epithelium migration. However, whether there are additional biological effects on eardrum regeneration is unclear for biological material patching in the clinic. This study evaluated the healing response for different repair patterns in human traumatic tympanic membrane perforations by endoscopic observation. In total, 114 patients with traumatic tympanic membrane perforations were allocated sequentially to two groups: the spontaneous healing group (n=57) and Gelfoam patch-treated group (n=57). The closure rate, closure time, and rate of otorrhea were compared between the groups at 3 months. Ultimately, 107 patients were analyzed in the two groups (52 patients in the spontaneous healing group vs. 55 patients in the Gelfoam patch-treated group). The overall closure rate at the end of the 3 month follow-up period was 90.4% in the spontaneous healing group and 94.5% in the Gelfoam patch-treated group; the difference was not statistically significant (p>0.05). However, the total average closure time was significantly different between the two groups (26.8±9.1 days in the spontaneous healing group vs. 14.7±9.1 days in the Gelfoam patch-treated group, p<0.01). In addition, the closure rate was not significantly different between the spontaneous healing group and Gelfoam patch-treated group regardless of the perforation size. The closure time in the Gelfoam patch-treated group was significantly shorter than that in the spontaneous healing group regardless of the perforation size (small perforations: 7.1±1.6 days vs. 12.6±3.9, medium-sized perforations: 13.3±2.2 days vs. 21.8±4.2 days, and large perforations: 21.2±4.7 days vs. 38.4±5.7 days

  15. Endoscopic therapy for esophageal perforation or anastomotic leak with a self-expandable metallic stent. (United States)

    Leers, Jessica M; Vivaldi, Carlo; Schäfer, Hartmut; Bludau, Marc; Brabender, Jan; Lurje, Georg; Herbold, Till; Hölscher, Arnulf H; Metzger, Ralf


    Leaks of the esophagus are associated with a high mortality rate and need to be treated as soon as possible. Therapeutic options are surgical repair or resection or conservative management with cessation of oral intake and antibiotic therapy. We evaluated an alternative approach that uses self-expandable metallic stents (SEMS). Between 2002 and 2007, 31 consecutive patients with iatrogenic esophageal perforation (n = 9), intrathoracic anastomotic leak after esophagectomy (n = 16), spontaneous tumor perforation (n = 5), and esophageal ischemia (n = 1) were treated at our institution. All were treated with endoscopic placement of a covered SEMS. Stent removal was performed 4 to 6 weeks after implantation. To exclude continuous esophageal leak after SEMS placement, radiologic examination was performed after stent implantation and removal. SEMS placement was successful in all patients and a postinterventional esophagogram demonstrated full coverage of the leak in 29 patients (92%). In two patients, complete sealing could not be achieved and they were referred to surgical repair. Stent migration was seen in only one patient (3%). After removal, a second stent with larger diameter was placed and no further complication occurred. Two patients died: one due to myocardial infarction and one due to progressive ischemia of the esophagus and small bowl as a consequence of vascular occlusion. Stent removal was performed within 6 weeks, and all patients had radiologic and endoscopic evidence of esophageal healing. Implantation of covered SEMS in patients with esophageal leak or perforation is a safe and feasible alternative to operative treatment and can lower the interventional morbidity rate.

    Glomuvenous malformation (GVM) is an inherited autosomal dominant trait. The lesions, which appear as bluish nodules or plaque-like cutaneous elevations, are usually tender and more firm than sporadic venous malformations. Conventionally, the lesions are thought to be limited to the cutaneous and subcutaneous tissue planes. The objective was to characterize the depth of involvement of GVM lesions. Magnetic resonance imaging (MRI) findings in GVM were retrospectively evaluated by two radiologists. The signal characteristics, tissue distribution, pattern of contrast enhancement of the lesions in GVM were documented. Thirty patients (19 female) aged 1-35 years (mean 18 years) were diagnosed with GVM based on clinical features (n = 20) and/or histopathological findings (n = 10). The lesions were present in the lower extremity (n = 15), upper extremity (n = 6), cervico-facial region (n = 6), pelvis (n = 2), and chest wall (n = 1). All patients had skin and subcutaneous lesions. Fifty percent of the patients (n = 15) demonstrated subfascial intramuscular (n = 15), intra-osseous (n = 1), and intra-articular involvement (n = 1). Contrary to the conventional belief that GVMs are generally limited to the skin and subcutaneous tissue, deep subfascial extension of the lesions is common. (orig.)

  17. Indications and efficacy of endoscopic vacuum-assisted closure therapy for upper gastrointestinal perforations. (United States)

    Ooi, Geraldine; Burton, Paul; Packiyanathan, Andrew; Loh, Damien; Chen, Richard; Shaw, Kalai; Brown, Wendy; Nottle, Peter


    Endoscopic vacuum-assisted closure (EndoVAC) therapy is a recent innovation described for use in upper gastrointestinal perforations and leaks, with reported success of 80-90%. It provides sepsis control and collapses the cavity preventing stasis, encouraging healing of the defect. Whilst promising, initial reports of this new technique have not established clear indications, feasibility and optimal technique. We analysed all patients who underwent EndoVAC therapy between 2014 and 2016. The technique involved a standard gastroscope, nasogastric tube and vacuum-assisted closure dressing kit, with endoscopic placement of the polyurethane sponge. Data were collected on indication, technique, sepsis control, outcomes and drainage volumes. Ten patients were treated. Average age was 56.7 ± 12.3 years. There were three mortalities. EndoVAC placement was feasible in nine patients and successful healing was observed in six patients. Failure was more likely in the cases of large (>8 cm), chronic or complex cavities. A three-phase response was seen in successful cases, with initial reduction in external drainage (average: 143-17 mL/day within 1 week), followed by a progressive reduction in inflammatory markers (2 weeks) and finally a healing phase with reduction in cavity size (3 weeks). EndoVAC therapy is a potentially useful adjunct to conventional treatments of a subset of upper gastrointestinal leaks and perforations when there is a contained cavity <8 cm. It appears less effective in an uncontained perforation or chronically established tract. It has clear advantages of being easily applied with readily available equipment and disposables. © 2016 Royal Australasian College of Surgeons.

    The endoscopic gastric perforation is a consequence of some endoscopic procedures and now a way to manage abdominal organs. This is the reason why endoscopists are studying a safe endoscopic repair. To evaluate an endoscopic closure method for the gastric opening in natural orifice transenteric surgery Short-term survival animal study. Ten White Landrace pigs underwent a gastric perforation of 1.8 cm in diameter under general anesthesia. The opening was repaired with stitch assembled in a T-tag anchor placed through the gastric wall with a needle. A plastic transparent chamber, adapted to the endoscope tip protected the abdominal organs from the needle puncture outside the stomach. Six T-tags were placed in most cases and the stitches were tied with a metallic tie-knot, forming three sutures. The animals received liquids in the same operative day. One shoot antibiotic was used. The leakage test was performed with a forceps and by air distention. No complication was detected in the postoperative course. One month later the endoscopy revealed a scar and some suture material was observed in all animals. The antral anterior gastric wall was clear with few adhesions in the laparotomy performed in the same time. The adhesions were intense in an animal in which a cholecystectomy was performed before the repair. The endoscopic repair using T-tag and a protector chamber is feasible, easy to perform and safe. Further studies are needed to show the real value of this kind of procedure.

  19. Endoscopic treatment of vesical and urethral perforations after tension-free vaginal tape (TVT) procedure for female stress urinary incontinence. (United States)

    Baracat, Fabio; Mitre, Anuar Ibrahim; Kanashiro, Hideki; Montellato, Nelson Ileo Dias


    Stress urinary incontinence is a problem that is prevalent in women, and its treatment with minimally invasive techniques using synthetic materials has increased recently, although the procedure has also brought increased occurrence of specific complications such as vesical and urethral perforations. We describe 11 cases of endoscopic correction of vesical and urethral perforations due to the use of synthetic material for the treatment of stress urinary incontinence. Eleven patients were treated for complications after undergoing the TVT(R) (tension-free vaginal tape) procedure; 6 of them had the polypropylene tape inside the bladder, and 5 had erosion of the urethra. Endoscopic resection of the polypropylene tapes was performed on all patients. A 6-month follow-up with cystoscopic control showed that the procedures were successful with complete relief of the symptoms except for 1 patient who persisted with the polypropylene tape in the bladder. This patient underwent a new endoscopic resection, and the cystoscopic control exam was normal 3 months later. Endoscopic resection of intravesical and intraurethral synthetic tapes can be considered a good alternative for the treatment of complications resulting from the TVT procedure.

  1. Endoscopic Vacuum-Assisted Closure (E-VAC) Treatment in a Patient with Delayed Anastomotic Perforation following a Perforated Gastric Conduit Repair after an Ivor-Lewis Esophagectomy (United States)

    Kwon, Se Hwan


    It has been reported that intrathoracic esophageal leakages occur at a rate of 4%–17% after Ivor-Lewis esophagectomy. There has been no consensus on a specific treatment for the post-operative anastomotic leakage. Recently, endoscopic vacuum-assisted closure (E-VAC) has been introduced as a novel treatment for the post-operative anastomotic leakage. We herein report the case of a patient with early perforation of the gastric conduit followed by late esophagogastric anastomotic leakage who was successfully treated with early surgical repair and subsequent E-VAC. The patient had been previously diagnosed with achalasia and squamous cell carcinoma of the esophagus and undergone an Ivor-Lewis esophagectomy. PMID:27075934

  2. Endoscopic Ultrasound-Guided Drainage of Intra-Abdominal Abscess after Gastric Perforation in a Patient Receiving Ramucirumab and Paclitaxel for Advanced Gastric Cancer

    Directory of Open Access Journals (Sweden)

    Koichiro Mandai


    Full Text Available Gastrointestinal perforation is a serious adverse event that occurs in approximately 1% of patients receiving ramucirumab and paclitaxel. A 67-year-old man with unresectable advanced gastric cancer was admitted to our hospital and treated with ramucirumab and paclitaxel. Gastric perforation occurred during the second cycle of chemotherapy. Although the patient’s condition improved without surgery, an abscess developed in the intra-abdominal fluid collection resulting from the perforation. We performed endoscopic ultrasound-guided abscess drainage. The patient improved and was discharged in satisfactory condition. Endoscopic ultrasound-guided drainage is a treatment option for patients with intra-abdominal abscess following gastric perforation due to ramucirumab.

    Full Text Available Blind oro-(naso-pharyngeal suction and feeding catheter intubation are very common practices in pediatric critical care. However, these simple procedures may produce unexpected complications in friable tiny patients. We encountered 3 extremely premature infants in whom cervical esophageal perforation and further submucosal excavation were caused by traumatic catheter injury and subsequently led to catastrophes. These episodes of iatrogenic trauma were all successfully diagnosed early, documented and managed with the aid of ultrathin flexible endoscopy.

  5. Conservative management of rectal perforation after nerve sparing endoscopic extraperitoneal radical prostatectomy (NSEERPE in a patient with a past history of polypectomy

    Directory of Open Access Journals (Sweden)

    Khoder WY


    Full Text Available Abstract Introduction Rectal polypectomy causes thinning (or even perforation of the rectal wall in addition to thermic injury at the polypectomy site. Case report We present a rare case of spontaneous rectal perforation after uncomplicated nerve sparing endoscopic extraperitoneal radical prostatectomy in a patient with a previous history of rectal polypectomy at the perforation site. The patient could be treated conservatively. There was complete healing of the fistula without any effect on functional results. This Conservative therapy for such rectal perforations is indicated if the patient's general condition remains stable without any signs of infection. Conclusions Polypectomy is an important risk factor for rectal perforation during nsEERPE. Adequate time interval should be given to allow healing and avoid adding further thermal wall damage which may obscure healing leading to complications like fistula. Conservative therapy for small missed rectal perforations constitutes an attractive, feasible and non invasive treatment entity. Following this principle we have not faced this complication in following similar cases.

    Full Text Available Background and Aim. Perforation after endoscopic retrograde cholangiopancreatography (ERCP is a rare complication, but it is associated with significant mortality. This study evaluated the early management experience of these perforations. Patients and Methods. Between November 2003 and December 2011, a total of 8504 ERCPs were performed at our regional endoscopy center. Sixteen perforations (0.45% were identified and retrospectively reviewed. Results. Nine of these 16 patients with perforations were periampullary, 3 duodenal, 1 gastric fundus, and 3 patients had a perforation of an afferent limb of a Billroth II anastomosis. All patients with perforations were recognized during ERCP by X-ray and managed immediately. One patient with duodenal perforation and three patients with afferent limb perforation received surgery, others received medical conservative treatment which included suturing lesion, endoscopic nasobiliary drainage (ENBD, endoscopic retrograde pancreatic duct drainage (ERPD, gastrointestinal decompression, fasting, broad-spectrum antibiotics, and so on. All patients with perforation recovered successfully. Conclusions. We found that: (1 the diagnosis of perforation during ERCP may be easy, but you must pay attention to it. (2 Most retroperitoneal perforations can recover with only medical conservative treatment in early phase. (3 Most peritoneal perforations need surgery unless you can close the lesion up under endoscopy in early phase.

  10. A new subfascial approach in open thyroidectomy: efficacy for postoperative voice, sensory, and swallowing symptoms. A randomized controlled study. (United States)

    Jung, Seung Pil; Kim, Sung Hoon; Bae, Soo Youn; Lee, Se Kyung; Kim, Sangmin; Choi, Min-Young; Kim, Jiyoung; Kim, Minkuk; Kil, Won Ho; Choe, Jun-Ho; Kim, Jung-Han; Nam, Seok Jin; Kim, Jee Soo


    After open thyroidectomy, patients usually complain of voice, sensory, and swallowing symptoms. We approached the thyroid via the subfascial method to reduce these symptoms and compared postthyroidectomy symptoms with the conventional subplatysmal method. Eighty-six patients undergoing thyroidectomy were recruited and randomized into either a conventional subplatysmal approach group (subplatysmal, 42 patients) group or a subanterior fascia of strap muscle approach group (subfascial, 44 patients). Voice symptoms were assessed using the Voice Handicap Index questionnaire and acoustic voice analysis. Sensory alterations were evaluated by the light touch and pain touch methods. Swallowing symptoms were assessed using the Swallowing Impairment Score (SIS) questionnaire, barium swallowing time, and hyoid bone movement range. Each variable was measured preoperatively, and at 2 weeks and 3 months after thyroidectomy. In both groups, the subjective symptoms of voice, sensation, and swallowing were significantly worsened at 2 weeks after operation, but improved 3 months after operation. Patients in the subplatysmal group had worse SIS scores than patients in the subfascial group (p = 0.016) and delayed barium swallowing time 2 weeks after operation (p = 0.008 compared to preoperative level). In the cohort over 50 years of age, SIS score did not recover to preoperative levels in the subplatysmal group 3 months after operation (p = 0.005 compared to preoperative level). The subfascial approach may be an effective method for reducing postthyroidectomy swallowing symptoms based on swallowing impairment score, especially in patients over 50 years of age.

  11. Perforated monolayers

    Energy Technology Data Exchange (ETDEWEB)

    Regen, S.L.


    Goal of this research program is to create ultrathin organic membranes that possess uniform and adjustable pores ( < 7[angstrom] diameter). Such membranes are expected to possess high permeation selectivity (permselectivity) and high permeability, and to provide the basis for energy-efficient methods of molecular separation. Work carried out has demonstrated feasibility of using perforated monolayer''-based composites as molecular sieve membranes. Specifically, composite membranes derived from Langmuir-Blodgett multilayers of the calix[6]arene-based surfactant shown below plus poly[l-(trimethylsilyl)-l-propyne] (PTMSP) were found to exhibit sieving behavior towards He, N[sub 2] and SF[sub 6]. Results of derivative studies that have also been completed are also described in this report.

  12. A Novel Skin and Fascia Opening for Subfascial Inserting of Intrathecal Baclofen Pump. (United States)

    Fiaschi, Pietro; Cama, Armando; Piatelli, Gianluca; Moretti, Paolo; Pavanello, Marco


    The aim of this article is to introduce a new skin and fascia opening for intrathecal baclofen pump implantation in the abdomen, with the purpose of reducing complications related to wound breakdown. We introduce a novel way of cutaneous and fascial opening that leads two opposed "L shaped" incisions. This method entails numerous advantages. The first advantage is avoiding the direct alignment of overlapped sutures, which creates a locus minoris resistentiae that can weaken and break under the push of the pump. Another advantage consists of an increased obstruction against deep extension of infective processes from cutaneous origin. The wide opening of the subfascial pocket permits the implantation of any type of pump available, and it reduces complexities in reopening the pouch for pump replacement. It also permits the fastening of all anchoring systems usually present in pumps. Another advantage is the improved possibility of careful muscle cauterization thanks to the wide fascia opening, with reduced risk of postsurgical hematoma. Our results showed a reduction of wound complications with this method. This method could contribute to reducing the rate of wound complications and patient discomfort. Copyright © 2017 Elsevier Inc.

    Paulo M. Rocha


    Full Text Available Abdominal obesity has been associated with liver fat storage. However, the relationships between other body composition depots and metabolic syndrome features with hepatic fat are still unclear. We examined abdominal and thigh adipose tissue (AT compartments associations with liver fat in 140 overweight and obese premenopausal Caucasian women. Blood lipids and, proinflammatory and atherothrombotic markers associations with hepatic fat were also analyzed. A larger visceral AT (VAT was related with liver fat (P<0.05. Contrarily, thigh subfascial AT was inversely related to liver fat (P<0.05. Increased fasting insulin, triglycerides, PAI-1 concentrations, and a higher total-cholesterol/HDL-cholesterol ratio were also associated with hepatic fat, even after adjustment for VAT (P<0.05. Thigh subfascial adiposity was inversely associated with liver fat, suggesting a potential preventive role against ectopic fat storage in overweight and obese women. These results reinforce the contribution of an abdominal obesity phenotype associated with a diabetogenic and atherothrombotic profile to liver lipotoxicity.

    Rueckauer, K.; Dinkel, E.


    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.

  2. Endoscopic tympanoplasty

    Directory of Open Access Journals (Sweden)

    Abdulvahap Akyigit


    Full Text Available Middle ear surgery is usually performed using a surgical microscope. Initially, in otorhinolaryngology practice, endoscopes were used for paranasal sinus surgeries. It was only later that they were applied in the area of otology. In otologic surgeries, endoscopes were first used to visualize the middle ear, before being used to assist with visualization of instruments during cholesteatoma surgeries, although they are still not used alone in various otologic surgeries. As in other surgical fields, there is also a trend towards minimally invasive intervention in the field of otorhinolaryngology. Smaller incisions performed under the guidance of endoscopes are preferred over conventional large incisions. Using this approach, improved outcomes can be achieved and postoperative morbidities can be reduced. In addition, the outcomes of grafts performed using the endoscopic approach are similar to that achieved by the microscopic approach. Therefore, endoscopic ear surgery implementations are becoming increasingly popular.

    Perforation of gastric cancer is rare and it accounts for less than 1% of the incidences of an acute abdomen. In this study, we reviewed cases of benign or malignant gastric perforation in terms of the accuracy of diagnosis and investigated the clinical outcome after emergency surgery in patients with a free perforation caused by gastric cancer. On the basis of pathological examination, gastric cancer was diagnosed in 8 patients and benign ulcer perforation in 32 patients. The sensitivity, specificity and accuracy of intraoperative diagnosis by pathological examination were 50, 93.8 and 85%, respectively. Except for age, there were no differences in the other demographic characteristics between patients with gastric cancer and benign ulcer perforation. The median survival time of patients with perforated gastric cancer was 195 days after surgery. Patients with gastric cancer perforation had a poorer overall survival rate than those who had T3 tumors without perforation. In addition, in patients with perforation, recurrence of peritoneum occurred more frequently. In conclusion, to improve the survival rate of patients with perforated gastric cancer and to improve the accuracy of intraoperative diagnosis, endoscopic examination and/or pathological examination of the frozen section should be performed, if possible. A balanced surgical strategy using laparoscopic local repair as the first-step of surgery, followed by radical open gastrectomy with lymphadenectomy may be considered.

  9. Endoscopy-assisted subfascial anterior transposition of the ulnar nerve for the treatment of cubital tunnel syndrome. (United States)

    Wong, J K F; Hsu, C C; Lin, C H; Lien, S H; Lin, Y T


    Many techniques have been described to relieve the compression and reduce subluxation of the ulnar nerve following surgery. The subfascial anterior transposition of the ulnar nerve (SfATUN) is one described technique, but involves a long scar, risk of injury to the medial antebrachial cutaneous nerve, and possible nerve ischemia from anterior transposition. We assessed a more refined approach of endoscopy-assisted SfATUN for the treatment of cubital tunnel syndrome. A consecutive case series of 21 patients (15 males and 6 females) with evidence of nerve subluxation after ulnar nerve decompression were operated using an endoscopy-assisted SfATUN. Each patient was assessed with pre- and postoperative nerve conduction studies, McGowan grading, and recovery of grip strength. The average age of patients was 54 years (range 23-74 years), and they were followed up for a mean of 9 months (range 3-22 months). Preoperative McGowan grades were eight grade II and 13 grade III. Eighteen of the 21 patients showed improvement, including improvement by two McGowen grades in 8 patients and improvement by one grade in 10 patients. Three grade III patients did not show improvement in grading after surgery. A proportion of 90% of patients showed significant improvements in motor nerve conduction velocity of the ulnar nerve across the elbow (p cubital tunnel syndrome and the "unstable" nerve.

  10. Endoscopically assisted aesthetic augmentation of tuberous breasts and fat grafting to correct the double bubble. (United States)

    Serra-Renom, Jose M; Muñoz-Olmo, Juan; Serra-Mestre, Jose M


    Treatment of tuberous breasts types 1 and 2 must deal with the problem of the pseudo-double bubble in the primitive inframammary fold and also must release the constrictive ring. Two techniques currently are used to overcome these problems, but neither is entirely satisfactory. The first technique, in which the approach is via the primitive inframammary fold, leaves significant scarring when the lower poles expand. The second technique, in which the approach is periareolar, considerably reduces the area's sensitivity. This report presents a new endoscopically assisted technique with an axillary approach designed to solve these problems. Between 2005 and 2010, 68 patients (ages 18-42 years) underwent surgery. The intervention was bilateral in 57 and unilateral in 11 of these patients. All cases involved tuberous breasts types 1 and 2 (Grolleau's classification). The augmentation involves a transaxillary subfascial endoscopic approach, opening of the fascia at the primitive inframammary fold, and releasing of the constricting ring to enable the breast to expand, followed by implantation of an anatomic prosthesis to add volume to the lower quadrants. If the pseudo-double bubble appears, fat grafting is applied during the same surgical procedure. The results were reported to be highly satisfactory both by the patients and by the independent medical team. For six patients (8.82 %), fat grafting had to be repeated in the double bubble. No major complications were reported. The endoscopically assisted subfascial breast augmentation technique obtains highly satisfactory results in tuberous breasts types 1 and 2 (Grolleau's classification). The single scar is concealed in the axillary fold. This journal requires that authors assign a level of evidence to each article.

    Rectal perforations due to glycerin enemas (GE) typically occur when the patient is in a seated or lordotic standing position. Once the perforation occurs and peritonitis results, death is usually inevitable. We describe two cases of rectal perforation and fistula caused by a GE. An 88-year-old woman presented with a large rectal perforation and a fistula just after receiving a GE. Her case was further complicated by an abscess in the right rectal wall. The second patient was a 78-year-old woman who suffered from a rectovesical fistula after a GE. In both cases, we performed direct endoscopic abscess lavage with a saline solution and closed the fistula using an over-the-scope-clip (OTSC) procedure. These procedures resulted in dramatic improvement in both patients. Direct endoscopic lavage and OTSC closure are very useful for pararectal abscess lavage and fistula closure, respectively, in elderly patients who are in poor general condition. Our two cases are the first reports of the successful endoscopic closure of fistulae using double OTSCs after endoscopic lavage of the debris and an abscess of the rectum secondary to a GE.

    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.

    Lohsiriwat, Varut; Sujarittanakarn, Sasithorn; Akaraviputh, Thawatchai; Lertakyamanee, Narong; Lohsiriwat, Darin; Kachinthorn, Udom


    AIM: To determine the incidence of colonoscopic perforation (CP), and evaluate clinical findings, management and outcomes of patients with CP from the World Gastroenterology Organization (WGO) Endoscopy Training Center in Thailand. METHODS: All colonoscopies and sigmoidoscopies performed between 1999 and 2007 in the Endoscopic unit, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok were reviewed. Incidence of CP, patients’ characteristics, endoscopic information, intra-operative findings, management and outcomes were analyzed. RESULTS: A total of 17 357 endoscopic procedures of the colon (13 699 colonoscopies and 3658 flexible sigmoidoscopies) were performed in Siriraj hospital over a 9-year period. Fifteen patients (0.09%) had CP: 14 from colonoscopy and 1 from sigmoidoscopy. The most common site of perforation was in the sigmoid colon (80%), followed by the transverse colon (13%). Perforations were caused by direct trauma from either the shaft or the tip of the endoscope (n = 12, 80%) and endoscopic polypectomy (n = 3, 20%). All patients with CP underwent surgical management: primary repair (27%) and bowel resection (73%). The mortality rate was 13% and postoperative complication rate was 53%. CONCLUSION: CP is a rare but serious complication following colonoscopy and sigmoidoscopy, with high rates of morbidity and mortality. Incidence of CP was 0.09%. Surgery is still the mainstay of CP management. PMID:19034978

    Jovanović Ivan


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

    Full Text Available Abstract Background Knowledge of the factors influencing colonoscopic perforation (CP is of decisive importance, especially with regard to the avoidance or minimization of the perforations. The aim of this study was to determine the incidence and risk factors of CP in one of the endoscopic training centers accredited by the World Gastroenterology Organization. Methods The prospectively collected data were reviewed of all patients undergoing either colonoscopy or flexible sigmoidoscopy at the Faculty of Medicine Siriraj Hospital, Bangkok, Thailand between January 2005 and July 2008. The incidence of CP was evaluated. Eight independent patient-, endoscopist- and endoscopy-related variables were analyzed by a multivariate model to determine their association with CP. Results Over a 3.5-year period, 10,124 endoscopic procedures of the colon (8,987 colonoscopies and 1,137 flexible sigmoidoscopies were performed. There were 15 colonic perforations (0.15%. Colonoscopy had a slightly higher risk of CP than flexible sigmoidoscopy (OR 1.77, 95%CI 0.23-13.51; p = 1.0. Patient gender, emergency endoscopy, anesthetic method, and the specialty or experience of the endoscopist were not significantly predictive of CP rate. In multivariate analysis, patient age of over 75 years (OR = 6.24, 95%CI 2.26-17.26; p Conclusion The incidence of CP in this study was 0.15%. Patient age of over 75 years and therapeutic colonoscopy were two important risk factors for CP.

    Kishida, Yoshihiro; Kakushima, Naomi; Kawata, Noboru; Tanaka, Masaki; Takizawa, Kohei; Imai, Kenichiro; Hotta, Kinichi; Matsubayashi, Hiroyuki; Ono, Hiroyuki


    Endoscopic dilation (ED) is used for the treatment of benign strictures caused by reflux esophagitis or anastomotic stenosis after esophagectomy. Esophageal stenosis is a major complication after endoscopic submucosal dissection (ESD) of large superficial esophageal cancer, but little is known regarding the incidence of complications of ED for stenosis caused by esophageal ESD. This was a retrospective study conducted at a single institution. From September 2002 to December 2012, a total of 1,337 ED procedures were performed for stenosis after esophageal ESD in 121 patients. The incidence of complications of ED and related clinical characteristics were analyzed. The incidence of bleeding was 0.8 % (1/121) per patient and 0.07 % (1/1,337) per procedure. The incidence of perforation was 4.1 % (5/121) per patient and 0.37 % (5/1,337) per procedure. Perforation occurred at a median of third time of ED procedures (range 2-9 procedures) and at a median of 18 days (range 8-29 days) after ESD. There were no significant characteristics correlated to perforation, such as location, circumferential extent, or diameter of mucosal defect after ESD. The total number of ED procedures was significantly larger among perforation cases (37, range 6-57) compared with those without perforation (7, range 1-70) (p = 0.01), and the treatment duration tended to be longer (190 vs. 69 days, respectively). The incidence of bleeding caused by ED for esophageal stenosis after ESD was very low. Relevant risk of perforation should be considered for patients requiring multiple ED procedures.

  5. Triple-Tube-Ostomy: A Novel Technique for the Surgical Treatment of Iatrogenic Duodenal Perforation

    Directory of Open Access Journals (Sweden)

    Nobuaki Fujikuni


    Full Text Available Although duodenal perforation is currently an infrequent complication of medical procedures, its incidence in the future predictably will increase as endoscopic treatment of duodenal neoplasms becomes more frequently used. In some cases, duodenal perforation is difficult to treat even surgically. We report here a novel technique called ‘triple-tube-ostomy’ for the treatment of iatrogenic duodenal perforation. Since November 2009, there have been three cases of iatrogenic perforation of the duodenum, due to various causes, which we have treated with our novel technique. The main principles of the technique are biliary diversion, decompression of the duodenum, and early enteral nutrition. All patients who underwent the triple-tube-ostomy procedure had good postoperative courses, with few complications. The novel surgical technique we describe in this report is safe, reliable, easy to learn and perform, and led to a good postoperative course in all cases where we performed it.

  10. Endoscopic Management of Nonlifting Colon Polyps

    Directory of Open Access Journals (Sweden)

    Shai Friedland


    Full Text Available Background and Study Aims. The nonlifting polyp sign of invasive colon cancer is considered highly sensitive and specific for cancer extending beyond the mid-submucosa. However, prior interventions can cause adenomas to become nonlifting due to fibrosis. It is unclear whether nonlifting adenomas can be successfully treated endoscopically. The aim of this study was to evaluate outcomes in a referral practice incorporating a standardized protocol of attempted endoscopic resection of nonlifting lesions previously treated by biopsy, polypectomy, surgery, or tattoo placement. Patients and Methods. Retrospective review of patients undergoing colonoscopy by one endoscopist at two hospitals found to have nonlifting lesions from prior interventions. Lesions with biopsy proven invasive cancer or definite endoscopic features of invasive cancer were excluded. Lesions ≥ 8 mm were routinely injected with saline prior to attempted endoscopic resection. Polypectomy was performed using a stiff snare, followed by argon plasma coagulation (APC if necessary. Results. 26 patients each had a single nonlifting lesion with a history of prior intervention. Endoscopic resection was completed in 25 (96%. 22 required snare resection and APC. 1 patient had invasive cancer and was referred for surgery. The recurrence rate on follow-up colonoscopy was 26%. All of the recurrences were successfully treated endoscopically. There was 1 postprocedure bleed (4%, no perforations, and no other complications. Conclusions. The majority of adenomas that are nonlifting after prior interventions can be treated successfully and safely by a combination of piecemeal polypectomy and ablation. Although recurrence rates are high at 26%, these too can be successfully treated endoscopically.

  11. Spontaneous Perforation of Pyometra

    Directory of Open Access Journals (Sweden)

    Begüm Yildizhan


    Full Text Available Pyometra is the accumulation of purulent material in the uterine cavity. Its reported incidence is 0.01–0.5% in gynecologic patients; however, as far as elderly patients are concerned, its incidence is 13.6% [3]. The most common cause of pyometra is malignant diseases of genital tract and the consequences of their treatment (radiotherapy. Other causes are benign tumors like leiomyoma, endometrial polyps, senile cervicitis, cervical occlusion after surgery, puerperal infections, and congenital cervical anomalies. Spontaneous rupture of the uterus is an extremely rare complication of pyometra. To our knowledge, only 21 cases of spontaneous perforation of pyometra have been reported in English literature since 1980. This paper reports an additional case of spontaneous uterine rupture.

  12. Transcanal microscope-assisted endoscopic myringoplasty in children. (United States)

    Migirov, Lela; Wolf, Michael


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

  14. Perforated Gastric Ulcer Associated with Anti-Angiogenic Therapy

    Directory of Open Access Journals (Sweden)

    Diogo Libânio


    Full Text Available Anti-angiogenic therapy with bevacizumab, an inhibitor of vascular endothelial growth factor, is commonly used in metastatic colorectal cancer and is rarely associated with gastrointestinal perforation, perforation being more frequent in the primary tumor site or at the anastomotic level. We present the case of a 64-year-old male with stage IV rectal adenocarcinoma who was on palliative chemotherapy with FOLFOX and bevacizumab. After the 4th chemotherapy cycle, our patient started fever and epigastric pain. He was hemodynamically stable, and signs of peritoneal irritation were absent. There were no alterations in the abdominal X-ray, and C-reactive protein was markedly elevated. A CT scan revealed a de novo thickness in the gastric antrum. Upper digestive endoscopy showed an ulcerated 40-mm lesion in the angulus, with a 20-mm orifice communicating with an exsudative cavity revested by the omentum. A conservative approach was decided including fasting, broad-spectrum intravenous antibiotics, and proton-pump inhibitors. Subsequent gastroduodenal series showed no contrast extravasation, allowing the resumption of oral nutrition. Esophagogastroduodenoscopy after 8 weeks showed perforation closure. Biopsies did not show neoplastic cells or Heliobacter pylori infection. Although the success in the conservative management of perforation allowing the maintenance of palliative chemotherapy (without bevacizumab, the patient died after 4 months due to liver failure. The reported case shows an uncommon endoscopic finding due to a rare complication of anti-angiogenic therapy. Additionally, it reminds clinicians that a history of gastroduodenal ulcers should be actively sought before starting anti-angiogenic treatment and that suspicion for perforation should be high in these cases.

  15. Perforated midgut diverticulitis: revisited. (United States)

    Spasojevic, Milan; Naesgaard, Jens Marius; Ignjatovic, Dejan


    To study and provide data on the evolution of medical procedures and outcomes of patients suffering from perforated midgut diverticulitis. Three data sources were used: the Medline and Google search engines were searched for case reports on one or more patients treated for perforated midgut diverticulitis (Meckel's diverticulitis excluded) that were published after 1995. The inclusion criterion was sufficient individual patient data in the article. Both indexed and non-indexed journals were used. Patients treated for perforated midgut diverticulitis at Vestfold Hospital were included in this group. Data on symptoms, laboratory and radiology results, treatment modalities, surgical access, procedures, complications and outcomes were collected. The Norwegian patient registry was searched to find patients operated upon for midgut diverticulitis from 1999 to 2007. The data collected were age, sex, mode of access, surgical procedure performed and number of patients per year. Historical controls were retrieved from an article published in 1995 containing pertinent individual patient data. Statistical analysis was done with SPSS software. Group I: 106 patients (48 men) were found. Mean age was 72.2 ± 13.1 years (mean ± SD). Age or sex had no impact on outcomes (P = 0.057 and P = 0.771, respectively). Preoperative assessment was plain radiography in 53.3% or computed tomography (CT) in 76.1%. Correct diagnosis was made in 77.1% with CT, 5.6% without (P = 0.001). Duration of symptoms before hospitalization was 3.6 d (range: 1-35 d), but longer duration was not associated with poor outcome (P = 0.748). Eighty-six point eight percent of patients underwent surgery, 92.4% of these through open access where 90.1% had bowel resection. Complications occurred in 19.2% of patients and 16.3% underwent reoperation. Distance from perforation to Treitz ligament was 41.7 ± 28.1 cm. At surgery, no peritonitis was found in 29.7% of patients, local peritonitis in 47.5%, and diffuse

  18. Endoscopic vs microscopic myringoplasty: a different perspective. (United States)

    Lade, Himani; Choudhary, Santosha Ram; Vashishth, Ashish


    The objectives of this study were to ascertain the feasibility of transcanal endoscopic underlay myringoplasty using temporalis fascia and compare the results with microscopic myringoplasty. This prospective randomized trial included 60 patients with mucosal chronic otitis media with tympanic membrane perforations of all sizes and locations apart from posteriorly based small or moderate sized perforations. In the endoscopy group, 30 patients underwent exclusive transcanal myringoplasty using tympanomeatal flap elevation with underlay graft placement. In the microscopy group, 30 patients underwent myringoplasty using the postaural approach. Intra-operative variables compared were canalplasty and canal wall curettage for assessment of ossicular status. Graft uptake, hearing outcomes using pure tone audiometry and subjective cosmetic outcomes were assessed 24 weeks post-operatively and compared in the two groups. Resident feedback on the feasibility of endoscopic myringoplasty was obtained using a questionnaire. In the microscopy group, 5/30 patients required canalplasty due to canal overhangs and 4/30 required canal wall curettage for ossicular assessment, whereas none of the patients in the endoscopy group required these procedures. A graft uptake rate of 83.3% was observed in both groups post-operatively after 24 weeks. Mean air-bone gap pre- and post-operatively in the endoscopy group was 28.5 and 18.13 dB, respectively, whereas these values were 32.4 and 16.9 dB, respectively, in the microscopy group. Subjective cosmetic outcomes were better in the endoscopy group. Resident feedback on endoscopic myringoplasty was positive. Endoscopic myringoplasty appears to be an effective alternative to microscopic myringoplasty and results in excellent hearing with good cosmetic outcomes.

  20. Helicobacter pylori in gastroduodenal perforation

    Directory of Open Access Journals (Sweden)

    Bharat B Dogra


    Full Text Available Background:peptic ulcers were earlier believed to be caused by dietary factors, gastric acid, and stress. However, in 1983, Warren and Marshall identified the correlation between Helicobacter pylori (H. pylori and peptic ulcers. It is now well established that most of the peptic ulcers occur as a result of H. pylori infection. But the co-relation between perforated peptic ulcer and H. pylori infection is not yet fully established. Aims and objectives : to study the prevalence of H. pylori infection in patients with perforated peptic ulcer. Materials and methods: this was a prospective study carried out in all cases of perforated peptic ulcer reporting in surgical wards of a medical college during 2008-2010. A total of 50 cases, presenting as acute perforation of duodenum and stomach during this period, formed the study group. After resuscitation, all the cases were subjected to emergency exploratory laparotomy. The exact site of perforation was identified, biopsy was taken from the ulcer margin from 2-3 sites and the tissue was sent for H. pylori culture and histopathological examination. Simple closure of perforation, omentoplasty, thorough peritoneal lavage and drainage was carried out. Results: out of the 50 cases of perforated peptic ulcer, 38 happened to be males, and only 12 were females. The age of the patients ranged from 20 to 70 years. All the patients underwent only emergency laparotomy. As many as 46 cases (92% turned out to be positive for H. pylori and only four cases (8% were negative for this infection. Postoperatively, patients who were found to be positive for H. pylori were put on anti-H. pylori treatment. Conclusion: there was a high prevalence of H. pylori infection in patients with perforated gastroduodenal ulcers.

    Full Text Available Herein we describe a new technical endoscopic removal of embedded partially covered esophageal stent that was inserted to treat a iatrogenic perforation of esophagus. Usually, partially covered stents can be removed by the stent-in-stent technique. In this case, the embedded stent could not be removed safely with this technique; so we performed a sub stent dissection to detach the stent from the esophageal wall.

    Bauer, Margit; Meining, Alexander; Kranzfelder, Michael; Jell, Alissa; Schirren, Rebekka; Wilhelm, Dirk; Friess, Helmut; Feussner, Hubertus


    The history of surgical antireflux treatment is coined by the search for better alternatives to Nissen fundoplication. Implantable devices are one option, beginning with the "Angelchik" prosthesis 30 years ago. However, this procedure was left soon because of the high rate of foreign body connected problems (migration, perforation). A modern approach is a magnetic sphincter augmentation device (LINX Reflux Management System, Torax Medical, Shoreview, MN, USA), a magnetic chain which is implanted laparoscopically. Advantages reported are simplicity to apply and good results in reflux control, with up to now only rare complication rates as reported in the literature (Lipham et al. in Dis Esophagus, 2014). We report one case of erosion of the esophagus by a LINX system resulting in severe dysphagia. A complete endoluminal removal could be achieved by a prototype OTSC-clip remover. Complete remission could be achieved. The technique is presented in detail (video). In principle, total endoscopic removal of the LINX device is feasible in case of major erosion.

    Jessa Baker


    Full Text Available History of present illness: A 53-year-old male with a history of daily alcohol abuse presented with sudden onset epigastric pain. The pain radiated to the right upper abdominal quadrant and was associated with shortness of breath and nausea. The patient’s vitals were notable for blood pressure of 181/107 and a heart rate of 124. He was in moderate distress and had a firm, distended abdomen with diffuse tenderness to palpation, without rebound or guarding. Significant findings: In the chest radiograph, there was obvious free air under the both the right diaphragm (above the liver and the left diaphragm, consistent with pneumoperitoneum. Discussion: A perforated ulcer is a surgical emergency. Overall mortality has been shown to be approximately 6.2%.1 Rapid diagnosis is essential as prognosis improves if treatment is initiated within the first six hours and worsens after 12 hours.2 The sensitivity for detecting pneumoperitoneum on plain radiography ranges from 50%-80%3-8 with specificity of 53%.7 An upright chest radiograph can detect as little as one to two milliliters of air.9,10 If free air is not seen on a posteroanterior (PA upright chest radiograph, an upright lateral chest radiograph can be obtained, which is more sensitive (98% sensitivity.8,11 About 10%-20% of ruptured ulcers will not present with visible free-air under the diaphragm on plain x-ray.12 In this case, given the free air seen on chest radiograph and peritoneal signs on exam, the patient was taken straight to the operating room for general surgery.

  6. Liver Abscess following Hematogenous Transmission due to Rectal Foreign Body Perforation

    Directory of Open Access Journals (Sweden)

    Martin Kobborg


    Full Text Available Liver abscess caused by hematogenous transmission from a gastrointestinal perforation by a foreign body is a rare but life-threatening condition. We present the case of a 57-year-old male with a pyogenic liver abscess generated on the basis of a foreign body perforation of the rectum. This has not been reported previously. During the examination of the patient, computed tomography scan showed not only the liver abscess but also an inflammatory presacral process, which communicated with the rectum through a 6.5-cm-long foreign body. Subsequent sigmoidoscopy showed a toothpick placed transmurally in the rectum; the toothpick was removed endoscopically. We discuss the importance of computed tomography scans and colonoscopies in relation to liver abscesses of unknown etiology, including the importance of detecting possible perforation caused by possible foreign bodies, polyps or cancer.

    Shahsanam Gheibi


    Full Text Available Background Foreign body ingestion is a relatively common in children. Most ingested foreign bodies spontaneously pass out of the body via the gastrointestinal (GI system but sharp materials may perforate the GI tract and need to surgical intervention. Case Presentation  The patient was a 9-year-old girl with progressive abdominal pain for one month and admitted with acute abdomen impression. She underwent esogastroduodenoscopy (EGD due to severe epigastric tenderness. Upper GI endoscopy revealed duodenal ulceration and perforation by a toothpick while she had no history of foreign body ingestion. Toothpick was removed by endoscopy. She was successfully managed conservatively and had no abdominal pain during the one month follow-up period. Conclusion We recommend the endoscopic approach as the preferable method for the extraction of duodenal foreign bodies in children, even in the case of intestinal perforation.

    Full Text Available BACKGROUND The duodenal injury can pose a formidable challenge to the surgeon and failure to manage it properly may have devastating results. Over the centuries, there was little to offer the patient of acute abdomen beyond cupping, purgation and enemas, all of which did more harm than good. It was not until 1884 that Mikulicz made an attempt to repair a perforation. Recent statistics indicate roughly 10% of population develop gastric or duodenal ulcer in life time. Roughly 1-3% of population above the age of 20 years have some degree of peptic ulcer activity during any annual period. A detailed history with regards to the signs and symptoms of the patient, a meticulous examination, radiological and biochemical investigations help to arrive at a correct preoperative diagnosis. In this study, a sincere effort has been put to understand the demographic patterns, to understand the underlying aetiology and to understand the effectiveness of the standard methods of investigation and treatment in use today. METHODS This is a 24 months prospective study i.e., from September 2011 to September 2013 carried out at Dr. Pinnamaneni Siddhartha Institute of Medical Sciences & Research Foundation. The study included the patients presenting to Dr. Pinnamaneni Siddhartha Institute of Medical Sciences & Research Foundation to emergency ward with signs and symptoms of hollow viscus perforation. The sample size included 30 cases of duodenal perforation. RESULTS Duodenal ulcer perforation commonly occurs in the age group of 30-60 years, but it can occur in any age group. Majority of the patients were male. Smoking and alcohol consumption were risk factors in most cases (53.3% for the causation of duodenal ulcer perforation. Sudden onset of abdominal pain, situated at epigastrium and right hypochondrium was a constant symptom (100%. Vomiting, constipation and fever were not so common. CONCLUSION The emergency surgical management for perforated duodenal ulcer is by

  9. SMAS Fusion Zones Determine the Subfascial and Subcutaneous Anatomy of the Human Face: Fascial Spaces, Fat Compartments, and Models of Facial Aging. (United States)

    Pessa, Joel E


    Fusion zones between superficial fascia and deep fascia have been recognized by surgical anatomists since 1938. Anatomical dissection performed by the author suggested that additional superficial fascia fusion zones exist. A study was performed to evaluate and define fusion zones between the superficial and the deep fascia. Dissection of fresh and minimally preserved cadavers was performed using the accepted technique for defining anatomic spaces: dye injection combined with cross-sectional anatomical dissection. This study identified bilaminar membranes traveling from deep to superficial fascia at consistent locations in all specimens. These membranes exist as fusion zones between superficial and deep fascia, and are referred to as SMAS fusion zones. Nerves, blood vessels and lymphatics transition between the deep and superficial fascia of the face by traveling along and within these membranes, a construct that provides stability and minimizes shear. Bilaminar subfascial membranes continue into the subcutaneous tissues as unilaminar septa on their way to skin. This three-dimensional lattice of interlocking horizontal, vertical, and oblique membranes defines the anatomic boundaries of the fascial spaces as well as the deep and superficial fat compartments of the face. This information facilitates accurate volume augmentation; helps to avoid facial nerve injury; and provides the conceptual basis for understanding jowls as a manifestation of enlargement of the buccal space that occurs with age. © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

    G. Bernard Taylor


    Full Text Available OBJECTIVE: To compare postoperative vaginal incision separation and healing in patients undergoing posterior repair with perforated porcine dermal grafts with those that received grafts without perforations. Secondarily, the tensile properties of the perforated and non-perforated grafts were measured and compared. MATERIALS AND METHODS: This was a non-randomized retrospective cohort analysis of women with stage II or greater rectoceles who underwent posterior repair with perforated and non-perforated porcine dermal grafts (PelvicolTM CR Bard Covington, GA USA. The incidence of postoperative vaginal incision separation (dehiscence was compared. A secondary analysis to assess graft tensile strength, suture pull out strength, and flexibility after perforation was performed using standard test method TM 0133 and ASTM bending and resistance protocols. RESULTS: Seventeen percent of patients (21/127 who received grafts without perforations developed vaginal incision dehiscence compared to 7% (5/71 of patients who received perforated grafts (p = 0.078. Four patients with vaginal incision dehiscence with non-perforated grafts required surgical revision to facilitate healing. Neither tensile strength or suture pull out strength were significantly different between perforated and non-perforated grafts (p = 0.81, p = 0.29, respectively. There was no difference in the flexibility of the two grafts (p = 0.20. CONCLUSION: Perforated porcine dermal grafts retain their tensile properties and are associated with fewer vaginal incision dehiscences.

  11. Laparoscopic treatment of perforated appendicitis (United States)

    Lin, Heng-Fu; Lai, Hong-Shiee; Lai, I-Rue


    The use of laparoscopy has been established in improving perioperative and postoperative outcomes for patients with simple appendicitis. Laparoscopic appendectomy is associated with less wound pain, less wound infection, a shorter hospital stay, and faster overall recovery when compared to the open appendectomy for uncomplicated cases. In the past two decades, the use of laparoscopy for the treatment of perforated appendicitis to take the advantages of minimally invasiveness has increased. This article reviewed the prevalence, approaches, safety disclaimers, perioperative and postoperative outcomes of the laparoscopic appendectomy in the treatment of patients with perforated appendicitis. Special issues including the conversion, interval appendectomy, laparoscopic approach for elderly or obese patient are also discussed to define the role of laparoscopic treatment for patients with perforated appendicitis.

    Although percutaneous endoscopic gastrostomy (PEG) is the preferred method to provide enteral nutrition for a longer time period, in obstructive esophageal cancer, we cannot safely perform endoscopic access to the stomach even with the ultrathin endoscope. We experienced 1 fatal case due to esophageal perforation caused by balloon dilation, and hence, we developed a safer method. We treated 4 patients with obstructive esophageal cancer using a 3-step gradual dilation method with nasogastric tubes (from 8 to 16 Fr). After about 2 weeks of initial dilation, we could safely perform endoscopic access to the stomach with the ultrathin endoscope and PEG placement using the introducer technique. The 3-step gradual dilation method is a safe and easy procedure for endoscopic access to the stomach. It can be used to provide enteral access as a palliative treatment for patients with obstructive esophageal cancer that is not suitable for conventional PEG placement.

  17. Laparoscopic management of a retroperitoneal duodenal perforation following ERCP for periampullary cancer. (United States)

    Palanivelu, Chinnusamy; Jategaonkar, Priyadarshan Anand; Rangarajan, Muthukumaran; Anand, Natesan Vijay; Senthilnathan, Palaniswamy


    Endoscopic retrograde cholangiopancreatography (ERCP) is a fairly common procedure being performed in several centers worldwide. Although it is proven to be efficient and relatively safe, complications do occur (1.8%). We present a patient with ERCP-induced retroperitoneal perforation of the duodenum treated laparoscopically at our institution. The patient is a 60-year-old female who underwent ERCP for obstructive jaundice due to periampullary carcinoma, during which the perforation occurred. Laparoscopy was performed 5 hours later and the perforation sutured primarily. The operating time was 125 minutes. On the fourth postoperative day, the patient developed a retroperitoneal collection, confirmed by computed tomographic scan. Re-look laparoscopy was performed and the fluid drained. She recovered completely and was discharged on the eighth postoperative day. Duodenal perforation following ERCP is rare, with an incidence of 1.8%. Both surgical and non-surgical management have been reported, each with its specific indications. Our patient needed surgery, because the perforation was large and a retroperitoneal collection was present. Laparotomy is the preferred approach, though now laparoscopy is a viable and effective alternative, because it provides the benefits of minimal access, such as reduced pain and early ambulation.

  18. Bilateral same-day endoscopic transcanal cartilage tympanoplasty: initial results. (United States)

    Daneshi, Ahmad; Jahandideh, Hesam; Daneshvar, Ali; Safdarian, Mahdi

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

    Full Text Available Multilateral well drilling and completion technology reduces well development cost and increases effectively the benefit and productivity of oil & gas well, which is widely used and expanded in recent years at home and abroad. Whipstock packer oriented perforating technology, a critical step in multilateral well drilling and completion, is for perforating whipstock packer and communicating lower branch wellbore. This technology meets the higher requirement of orientation and accuracy of penetration, perforator being able to perforate whipstock packer but not perforate outer casing of whipstock, and also meets complicated operation process.

  20. Repair of Tympanic Membrane Perforations with Customized Bioprinted Ear Grafts Using Chinchilla Models. (United States)

    Kuo, Che-Ying; Wilson, Emmanuel; Fuson, Andrew; Gandhi, Nidhi; Monfaredi, Reza; Jenkins, Audrey; Romero, Maria; Santoro, Marco; Fisher, John P; Cleary, Kevin; Reilly, Brian


    The goal of this work is to develop an innovative method that combines bioprinting and endoscopic imaging to repair tympanic membrane perforations (TMPs). TMPs are a serious health issue because they can lead to both conductive hearing loss and repeated otitis media. TMPs occur in 3-5% of cases after ear tube placement, as well as in cases of acute otitis media (the second most common infection in pediatrics), chronic otitis media with or without cholesteatoma, or as a result of barotrauma to the ear. About 55,000 tympanoplasties, the surgery performed to reconstruct TMPs, are performed every year, and the commonly used cartilage grafting technique has a success rate between 43% and 100%. This wide variability in successful tympanoplasty indicates that the current approach relies heavily on the skill of the surgeon to carve the shield graft into the shape of the TMP, which can be extremely difficult because of the perforation's irregular shape. To this end, we hypothesized that patient specific acellular grafts can be bioprinted to repair TMPs. In vitro data demonstrated that our approach resulted in excellent wound healing responses (e.g., cell invasion and proliferations) using our bioprinted gelatin methacrylate constructs. Based on these results, we then bioprinted customized acellular grafts to treat TMP based on endoscopic imaging of the perforation and demonstrated improved TMP healing in a chinchilla study. These ear graft techniques could transform clinical practice by eliminating the need for hand-carved grafts. To our knowledge, this is the first proof of concept of using bioprinting and endoscopic imaging to fabricate customized grafts to treat tissue perforations. This technology could be transferred to other medical pathologies and be used to rapidly scan internal organs such as intestines for microperforations, brain covering (Dura mater) for determination of sites of potential cerebrospinal fluid leaks, and vascular systems to determine arterial

    Sanna, Stefano; Taurchini, Marco; Mengozzi, Marta; Monteverde, Marco; Argnani, Desiderio; Dell'Amore, Davide


    Esophageal perforation has been considered a catastrophic and often life-threatening event, with very high mortality rates. Most of the cases are due to a complication in endoscopic manouvers and the best treatment, conservative rather than aggressive, remains a controversial topic. In 1995-2005 period we observed 7 cases of esophageal perforation, 5 women and 2 men mean age 73.2 y (range 60-87). Three cases are due to foreign body ingestion, 2 cases to endoscopic manoeuvres, 2 cases were spontaneous. In 3 cases the lesion was in the cervical tract of the esophagus, in the thoracic tract the others. All the patients were admitted very early to our Unit and presented disphagia, vomiting and dyspnoea, 2 out of them also a pleural effusion. In iatrogenic perforation we performed a cervicotomy and a drainage of mediastinic abscess, while in spontaneous lesions mono (one case) or bipolar esophageal exclusion (one case) with primary suture, jujunostomy and drainage of pleural effusion were the treatment. In foreign body perforation we performed thoracotomic and cervicotomic esophagotomy, extraction of the foreign body, direct suture with pleural or muscle protection. We didn't observe any intra or post-operative mortality. About the complications, we observed a bilateral pleural empyema, a chylous fistula, a digestive bleeding due to gastric ulcer, a laparotomic infection, a parossistic FA and a persistent esophageal fistula. Mean hospital stay was 24.3 days (range 10-43). All the patients were discharged to the hospital in good conditions. In conclusion in most of the cases of esophageal perforation the surgical treatment is the treatment of choice for its lower morbidity and mortality and good functional results.

  2. Perforating ocular injury by Taser. (United States)

    Chen, Sandy L; Richard, Christen K; Murthy, Raghu C; Lauer, Andreas K


    This report describes the features, treatment and outcome of globe perforation by a Taser dart electrode in a 21-year-old man. The Taser electrode caused mechanical iris, lens and retinal injury and consequent retinal detachment as result of proliferative vitreoretinopathy. The effect of electrical stimulation on ocular tissues is unknown. After the scleral and corneal wounds, traumatic cataract and retinal tear were repaired, the patient regained a visual acuity of 6/18. Nine months later a retinal detachment with proliferative vitreoretinopathy was discovered. The Taser may cause globe perforation and posterior segment injury. Understanding the barbed configuration of the dart electrode is important when extricating this device. Visual recovery is possible despite electric discharge of the Taser and suggests that the mechanism of ocular injury is largely mechanical.

  3. Percutaneous transgastric interventional radiology-operated duodenoscopy for the identification of duodenal perforation and Graham patch dehiscence

    Directory of Open Access Journals (Sweden)

    Ravi Nara Srinivasa, MD


    Full Text Available Patients with a Roux-en-Y gastric bypass may be challenging diagnostic and therapeutic dilemmas for gastroenterologists and endoscopists due to anatomic considerations. Pancreaticobiliary limb pathology is particularly difficult to diagnose from standard endoscopic approaches as it often requires double balloon enteroscopy. Percutaneous access and gastrostomy placement into the gastric remnant, however, is a commonly performed procedure by interventional radiology. This report describes the identification of duodenal perforation and Graham patch dehiscence in the pancreaticobiliary limb of a patient with a prior Roux-en-Y gastric bypass who had failed traditional endoscopic measures, using transgastric remnant interventional duodenoscopy and confirmed with methylene blue injection into a periduodenal abscess.

    Li, Bin; Liang, Tiejun; Wei, Lili; Ma, Mingze; Huang, Ya; Xu, Hongwei; Shi, Xiuju; Qin, Chengyong


    Endoscopic Interventional Treatment is of little trauma and less complications in the treatment of gastric schwannoma and leads to faster recovery and fewer days of hospitalization. This study was aimed to investigate the safety and efficacy of endoscopic interventional therapy for gastric schwannoma, including endoscopic submucosal excavation, non-laparoscopic-assisted endoscopic full-thickness resection, endoscopic tunneling submucosal resection, and so on. Six patients of gastric schwannoma diagnosed by pathology examination were retrospectively analyzed ranging from Oct 2011 to Feb 2014 at Shandong Provincial Hospital affiliated to Shandong University. Five of the six patients accepted endoscopic interventional therapy. Among the five patients, there were four males and one female, aged from 48 to 65 years old (the average age was 58 ± 6.4). The lesions located at the fundus, the fundus-cardia, gastric body or gastric antrum, respectively, with the diameters ranged from 8 to 25 millimeter (the average was 17.1 ± 7.8 mm). All the patients were performed endoscopic interventional therapy successfully. Among five patients, one patient was treated by endoscopic tunneling submucosal resection, two by endoscopic submucosal excavation, and the other two were given endoscopic full-thickness resection. Operation duration was about 43 to 83 minutes (the average was 57.6 ± 16.1 minutes). The mass were completely removed, with limited bleeding. During the operation, perforation and pneumoperitoneum occurred in two patients, who finally recovered by endoscopic and conservative treatment. No bleeding, inflammation or infection occurred in these patients. The average follow-up time was (7.4 ± 4.4) months. Neither recurrence nor metastasis was found during follow-up. Endoscopic interventional therapy is a safe and effective treatment for gastric schwannoma.

    Background: To assess the value of computed tomography (CT) in patients with acute perforated sigmoid diverticulitis in correlation with the Hinchey classification of perforated diverticular disease. Methods: Thirty patients with acute perforated sigmoid diverticulitis underwent computed tomography prior to surgery. Computed tomography scans were compared with the surgical and histopathological reports, utilizing the Hinchey classification. Results: In 28 of the 30 (93%) patients examined, the Hinchey stage was correctly determined by means of computed tomography. One patient with Hinchey stage IV was falsely classified as Hinchey stage III, and one patient with Hinchey stage III as Hinchey stage II. Computed tomography revealed 12 out of 14 (86%) patients with perforation sites and 3 out of 3 (100%) patients with contained perforation. In one of 17 (6%) patients with surgically or histopathologically proven perforation or contained perforation, a bowel wall discontinuity was revealed by computed tomography. In 6 of the 17 (35%) patients with surgical or histopathological perforation or contained perforation, extraluminal contrast material was detected by computed tomography. Conclusions: Computed tomography is a valuable imaging tool for determining the degree of acute perforated sigmoid diverticulitis, by means of which patients can be stratified according to the severity of the disease; furthermore, this tool is of assistance in surgical planning.

  8. Identification and management of inverted or everted edges of traumatic tympanic membrane perforations. (United States)

    Lou, Zhengcai; Lou, Zi-Han


    Most of traumatic tympanic membrane perforations have inverted or everted edges, however, the effects of inverted and everted edges on the spontaneous healing of the eardrum remain controversial. We investigated the influence of inverted or everted edges on the spontaneous healing of traumatic tympanic membrane perforations. The clinical records of patients with a traumatic tympanic membrane perforations who met the study criteria were retrieved and categorized into two groups, based on whether the eardrum was inverted or everted. The features along the edge of each inverted or everted eardrum were described using 30° and 70° endoscopes. In total, 196 patients (196 ears) met the inclusion criteria; of these, 148 had inverted or everted eardrums while 48 did not. Of the 148 patients with inverted or everted eardrums, the perforation edges were everted in 77 patients, inverted in 44 patients, drooping in 17 patients, and both inverted and everted in 10 patients. The perforation shape was triangular in 18.9% of patients, sector-shaped in 11.5%, kidney-shaped in 14.2%, ovoid in 20.3%, and irregularly shaped in 35.1% of patients. The difference was not significant between the with and without inverted/everted eardrum edges groups in terms of the closure rate or closure time. Similarly, the difference was not significant between the with and without edge approximation groups in terms of the closure rate or closure time at the end of the 12-month follow-up period. This study suggests that endoscopic inspection can clearly identify inverted/everted eardrum edges using 30° and 70° endoscopes. The edge is glossy in inverted/everted eardrums, whereas the edge is rough and irregular in non-inverted/everted cases. The inverted/everted eardrums gradually became necrotic, but this did not affect the healing process. Additionally, edge approximation did not improve the healing outcome of traumatic tympanic membrane perforations. Copyright © 2017 Associação Brasileira de

    Spirou Spiros


    Full Text Available Abstract Background Since its introduction in the early 1980s, percutaneous endoscopic gastrostomy has become the most popular method for performing a gastrostomy for long-term enteral feeding. It has been associated, however, with a lot of minor and major complications. Case presentation A case of mediastinitis with concominant sepsis caused by a masked esophageal perforation after percutaneous endoscopic gastrostomy in a multi-traumatized, brain-injured patient is presented. Ten – fourteen days after the procedure, the patient became febrile and gradually septic with tenderness of the sternum and upper abdomen. Computerized tomography of the thorax revealed mediastinitis. An urgent left thoracotomy and laparotomy were performed for drainage of the mediastinum, removal of the gastrostomy and insertion of a jejunostomy tube. The patient improved soon after the surgery. He was successfully weaned off the ventilator and was discharged from the Intensive Care Unit. Conclusion Perforating mediastinitis is a rare but potentially lethal complication of percutaneous endoscopic gastrostomy. When diagnosed and properly treated it may have a favourable outcome.

    Colorectal endoscopic submucosal dissection (ESD) has not been standardized due to technical difficulties and requires extensive training for reliability. Ex vivo animal model is convenient, but has no blood flow. The objective of this study is to evaluate the characteristics of various ex vivo animal models including a blood flow model for colorectal ESD training and the usefulness of practicing endoscopic hemostasis and closure using an animal model. Harvested porcine cecum, rectum, and stomach and bovine cecum and rectum were analyzed regarding ease of mucosal injection, degree of submucosal elevation, and status of the proper muscle layer. Ex vivo animal model with blood flow was made using the bovine cecum. The vessel around the cecum was detached, and red ink was injected. Endoscopic hemostasis for perioperative hemorrhage and endoscopic closure for perforation were performed in this model. Mucosal injection was easily performed in the bovine cecum and rectum. Submucosal elevation was low in the bovine cecum, while the proper muscle layer was not tight in the porcine rectum and bovine cecum. Endoscopic hemostasis were accomplished in six (60 %) out of ten procedures of the ex vivo blood flow model. In two non-experts, the completion rates of endoscopic closure were 40 and 60 % in the first five procedures. These rates became 100 % in the last five procedures. We have evaluated the characteristics of various ex vivo animal models and shown the possibility of training for endoscopic hemostasis and endoscopic closure in the ex vivo animal model.

  11. Endoscopic management of erosion after banded bariatric procedures. (United States)

    Spann, Matthew D; Aher, Chetan V; English, Wayne J; Williams, D Brandon


    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

    Full Text Available Background: To study the aetiology, management and outcome of biliary perforations in paediatric age group. Patients and Methods: In a retrospective study, the records of patients presented with biliary peritonitis due to biliary perforations, managed from March 2006 to July 2009, are reviewed. Results: Eight male patients with biliary peritonitis due to biliary perforation were managed. These patients were divided in two groups, A and B. Group A, (n = 3 patients, had common bile duct (CBD perforation, and Group B (n=5 patients had gallbladder perforation. The presenting features were abdominal pain, fever, abdominal distension, vomiting, constipation, jaundice and signs of peritonism. The management of CBD perforations in Group A was by draining the site of perforation and biliary diversion (tube cholecystostomy. In Group B, the gallbladder perforations were managed by tube cholecystostomy in four patients and cholecystectomy in one patient, however, one patient had to be re-explored and cholecystectomy performed due to complete necrosis of gall bladder. There was no mortality in our series. All patients were asymptomatic on regular follow-up. Conclusion: Early optimal management of biliary perforations remarkably improved the very high mortality and morbidity that characterised this condition in the past.

  16. Gastric schwannoma presenting with perforation and abscess formation: a case report and literature review. (United States)

    Euanorasetr, Chakrapan; Suwanthanma, Weerapat


    Gastric schwannoma represent only 0.2% of all gastric tumors and 4% of all benign gastric neoplasms. They are usually asymptomatic but can present with variable symptoms. The authors report a case of a 29-year-old male patient who presented with fever and abdominal pain with epigastric mass. Pre-operative diagnosis was gastric lymphoma with perforation and an abscess formation. Hemigastrectomy with Billroth II anastomosis was performed The pathologic examination and immunohistochemical studies confirmed gastric schawannoma as the diagnosis. The post-operative course was uneventful. Gastric schwannoma are difficult if not impossible to diagnose preoperatively as endoscopic and radiologic findings are nonspecific. The treatment of choice is complete surgical resection because of diagnostic uncertainty and the long-term outcome is excellent. This is the first report of gastric schwannoma presenting with concealed perforation and an abscess formation. The literature was reviewed.

  17. [Successful Removal of Hard Sigmoid Fecaloma Using Endoscopic Cola Injection]. (United States)

    Lee, Jong Jin; Kim, Jeong Wook


    Colorectal fecaloma is hardening of feces into lumps of varying size that is much harder in consistency than a fecal impaction. Complications of colorectal fecaloma include ulceration, bleeding, perforation and obstruction of the colon. Most fecalomas are successfully removed by conservative treatment with laxatives, enemas and rectal evacuation to relieve fecal impaction. When conservative treatments have failed, a surgical intervention may be needed. Herein, we report a case of 4.7 cm sized sigmoid fecaloma showing no response to conservative treatments that was successfully removed by endoscopic fragmentation with Coca-Cola injection instead of surgery.

  5. A Comparative Study of Endoscopic and Microscopic Approach Type 1 Tympanoplasty for Simple Chronic Otitis Media. (United States)

    Huang, Tzu-Yen; Ho, Kuen-Yao; Wang, Ling-Feng; Chien, Chen-Yu; Wang, Hsun-Mo


    Tympanoplasty is a common surgery for chronic otitis media. We analyzed the results of endoscopic and microscopic approaches for type 1 tympanoplasty in patients with simple chronic otitis media. We evaluated the records of 95 patients (100 ears) who underwent type 1 tympanoplasty from 2011 to 2014. Group 1 underwent tympanoplasty with a microscopic approach (50 ears), and Group 2 underwent tympanoplasty with an endoscopic approach (50 ears). The epidemiological profiles and postoperative results, including hearing gain, duration of surgery, perioperative nausea or vomiting, and graft success rate, were reviewed. The epidemiological profiles and preoperative hearing status were similar in both groups. Postoperatively, both groups had equal improvements in hearing and air-bone gap as well as equal perforation rates. However, the endoscopic group suffered less perioperative nausea or vomiting and had a shorter operative time. The endoscopic approach for tympanoplasty offers superior visualization and shorter operative time than conventional surgery, in addition to equal hearing outcomes and perforation rates. Furthermore, observations of fewer tissue injuries, better cosmetic outcomes, and lesser perioperative nausea and vomiting suggest that the endoscopic approach is a better choice for surgery.

  6. Investigation on the Acoustic Absorption of Flexible Micro-Perforated Panel with Ultra-Micro Perforations (United States)

    Li, Guoxin; Tang, Xiaoning; Zhang, Xiaoxiao; Qian, Y. J.; Kong, Deyi


    Flexible micro-perforated panel has unique advantages in noise reduction due to its good flexibility compared with traditional rigid micro-perforated panel. In this paper, flexible micro-perforated panel was prepared by computer numerical control (CNC) milling machine. Three kinds of plastics including polyvinylchloride (PVC), polyethylene terephthalate (PET), and polyimide (PI) were taken as the matrix materials to prepare flexible micro-perforated panel. It has been found that flexible micro-perforated panel made of PET possessing good porosity and proper density, elastic modulus and poisson ratio exhibited the best acoustic absorption properties. The effects of various structural parameters including perforation diameter, perforation ratio, thickness and air gap have also been investigated, which would be helpful to the optimization of acoustic absorption properties.

  7. Intestinal perforation secondary to metastasic lung carcinoma

    Directory of Open Access Journals (Sweden)

    M. C. Álvarez Sánchez


    Full Text Available Secondary symptomatic gastrointestinal metastases from lung primary tumor are rare. They can cause a variety of clinical conditions such as perforation, obstruction and bleeding. Intestinal perforations of intestinal metastases have a very poor prognosis. We present a case of a patient with metastatic lung cancer who presents with intestinal perforation and pneumoperitoneum. A 67 year old male, immunosuppressed and smoker is diagnosed with acute abdomen secondary to perforation of a tumor of the terminal ileum, as well as three other similar injuries. Resection and anastomosis. The patient died two months after surgery. The final pathological diagnosis supports epidermoidide poorly differentiated lung carcinoma. It was concluded that given an intestinal perforation in a patient diagnosed with lung carcinoma, it shouldn´t be excluded the metastases origen . Surgery is a purely palliative procedure.

    He, Shi-Ming; Wang, Yuan; Zhao, Tian-Zhi; Zheng, Tao; Lv, Wen-Hai; Zhao, Lan-Fu; Chen, Long; Sterling, Cole; Qu, Yan; Gao, Guo-Dong


    Symptomatic cavernous malformations involving the brainstem are difficult to access by conventional approaches, which often require dramatic brain retraction to gain adequate operative corridor. Here, we present a successful endoscopic endonasal transclival approach for resection of a hemorrhagic, symptomatic mesencephalic cavernous malformation. A 20-year-old woman presented with acute onset of headache, nausea, and vomiting. Computed tomography scan revealed a ventral midbrain hemorrhage. On day 3 of admission, the patient developed left-sided hemiparesis, restriction of medial and lateral left-eye movements, and loss of left pupillary light reflex. Subsequent magnetic resonance imaging demonstrated an increase of the midbrain lesion to 1.2 cm × 1.7 cm. Diffusion tensor imaging showed compression and lateral displacement of the right corticospinal tract near the thalamus and cerebral peduncle. Given the patient's clinical presentation and the findings on imaging, we suspected a mesencephalic cavernous malformation. The patient underwent an endoscopic endonasal transclival resection of a ventral midline mesencephalon cavernous malformation. A dark red lesion was directly visualized under the endoscope. After a small cortiectomy, the pial and perforator vessels were dissected, and dark-brown blood was drained from the cavernoma cavity. Using a biopsy forceps and with careful attention to the cavernoma borders, the lesion was removed and hemostasis was achieved. Pathologic examination confirmed cavernous malformation. One week after the operation, magnetic resonance imaging demonstrated total resection of the lesion. A 3-month follow-up revealed improved neurologic symptoms with minimal surgical morbidity.

  9. Endoscopic Removal of Foreign Bodies in Children

    Directory of Open Access Journals (Sweden)

    Chien-Heng Lin


    Full Text Available The ingestion of foreign bodies such as coins, fish bones, plastic toy parts, batteries, and needles is common in children. Although the majority of ingested foreign bodies pass through the gastrointestinal tract unaided, some children require either nonsurgical or surgical intervention. The medical records of children who presented to the pediatric emergency department of a single tertiary referral center between December 2001 and May 2006 were reviewed. A total of 87 patients underwent an endoscopic procedure because of suspected foreign body ingestion and foreign bodies were identified by endoscopy in 74 patients (85.1%. The mean age of these 74 patients was 3.4 years (range, 6 months to 13 years. The most common site of foreign body lodgment was the esophagus (n=38,51.4%; other sites included the stomach (n=33,44.6% and duodenum (n=3, 4.0%. The types of foreign bodies included coins (n=42, 56.8%, button batteries (n = 16, 21.6%, sharp objects (n = 9, 12.2%, chicken bones (n = 2, 2.7% and others (n=5, 6.7%. Only two foreign bodies (button batteries in the duodenum could not be removed successfully by endoscopy. Instead, they were moved into the intestine and then eliminated spontaneously the following day. There were no major complications caused by foreign body ingestion or endoscopic procedures. The outcome of all patients was uneventful without morbidity or mortality. In our experience, endoscopic removal of foreign bodies under general anesthesia is an effective and safe method in children; the method also prevents erosion and perforation of the gastrointestinal tract.

  10. Preoperative endoscopic diagnosis of superficial non-ampullary duodenal epithelial tumors, including magnifying endoscopy (United States)

    Tsuji, Shigetsugu; Doyama, Hisashi; Tsuji, Kunihiro; Tsuyama, Sho; Tominaga, Kei; Yoshida, Naohiro; Takemura, Kenichi; Yamada, Shinya; Niwa, Hideki; Katayanagi, Kazuyoshi; Kurumaya, Hiroshi; Okada, Toshihide


    Superficial non-ampullary duodenal epithelial tumor (SNADET) is defined as a sporadic tumor that is confined to the mucosa or submucosa that does not arise from Vater’s papilla, and it includes adenoma and adenocarcinoma. Recent developments in endoscopic technology, such as high-resolution endoscopy and image-enhanced endoscopy, may increase the chances of detecting SNADET lesions. However, because SNADET is rare, little is known about its preoperative endoscopic diagnosis. The use of endoscopic resection for SNADET, which has no risk of metastasis, is increasing, but the incidence of complications, such as perforation, is significantly higher than in any other part of the digestive tract. A preoperative diagnosis is required to distinguish between lesions that should be followed up and those that require treatment. Retrospective studies have revealed certain endoscopic findings that suggest malignancy. In recent years, several new imaging modalities have been developed and explored for real-time diagnosis of these lesion types. Establishing an endoscopic diagnostic tool to differentiate between adenoma and adenocarcinoma in SNADET lesions is required to select the most appropriate treatment. This review describes the current state of knowledge about preoperative endoscopic diagnosis of SNADETs, such as duodenal adenoma and duodenal adenocarcinoma. Newer endoscopic techniques, including magnifying endoscopy, may help to guide these diagnostics, but their additional advantages remain unclear, and further studies are required to clarify these issues.

  12. A microdissection study of perforating vessels in the perineum: implication in designing perforator flaps. (United States)

    Jin, Bai; Hasi, Wulan; Yang, Chao; Song, Jianxing


    The objective of this study is to determine the quantity, position, and caliber of perforating vessels in the perineum, and to provide an anatomic basis for designing perineal perforator flaps. Eleven adult cadavers (22 sides) were dissected under an operating microscope (x10). Microstructures, including perforating arteries, vena comitantes, vascular anastomoses, and cutaneous nerves, were measured with a sliding caliper (accurate to 0.2 mm). There were 4 relatively constant perforating arteries in the perineum: inguinal and perineal perforating branches of the superficial external pudendal artery, a perforating branch of the anterior cutaneous branch of the obturator artery, and a perforating branch of the lateral branch of the posterior scrotal (pudendal) artery. All 4 arteries were direct perforating branches. These perforating arteries and accompanying veins overlapped with each other and formed the upper, middle, and lower parts of the vascular anastomosis in deep fascia above the adductor wall. There were 4 important cutaneous nerves in the region originating from the following nerves: the genitofemoral nerve, ilioinguinal nerve, posterior scrotum (labium) major nerve, and rami perineales nervi cutanei femoris posterioris. The perineum has abundant blood supply, venous return, and innervation. Due to its covert location and manoeuvrability, perforator flaps from this region are good sources of donor tissue for perineal reconstruction.

    Objective: To identify the computed tomography findings suggestive of intestinal perforation by an ingested foreign body. Materials and Methods: This was a retrospective study of four cases of surgically proven intestinal perforation by a foreign body, comparing the computed tomography findings with those described in the literature. Results: None of the patients reported having ingested a foreign body, all were over 60 years of age, three of the four patients used a dental prosthesis, and all of the foreign bodies were elongated and sharp. In all four patients, there were findings indicative of acute abdomen. None of the foreign bodies were identified on conventional X-rays. The computed tomography findings suggestive of perforation were thickening of the intestinal walls (in all four cases), increased density of mesenteric fat (in all four cases), identification of the foreign body passing through the intestinal wall (in three cases), and gas in the peritoneal cavity (in one case). Conclusion: In cases of foreign body ingestion, intestinal perforation is more common when the foreign body is elongated and sharp. Although patients typically do not report having ingested such foreign bodies, the scenario should be suspected in elderly individuals who use dental prostheses. A computed tomography scan can detect foreign bodies, locate perforations, and guide treatment. The findings that suggest perforation are thickening of the intestinal walls, increased mesenteric fat density, and, less frequently, gas in the peritoneal cavity, often restricted to the point of perforation.

    Kim, Young Mook; Park, Byung Ran; Kim, Se Jong; Ko, Kang Seok; Park, Weon Gyoo; Moon, Un Hyun; Lee, Jeong Seok [Kwangju Christian Hospital, Kwangju (Korea, Republic of)


    To evaluate the CT grading of complications developing after endoscopic sphinc-terotomy(EST), and their clinical course. We retrospectively evaluated CT in 19 patients in whom pancreatitis or duodenal perforation developed after EST in 594 patients. The CT grading of pancreatitis was classified as mild, moderate or severe, according to the extent of peripancreatic infiltration;duodenal perforation was classified as mild, moderate or severe grade, according to the extent of fluid collection. We attempted to correlate CT grade with the average duration of hospitalization after EST, treatment method and mortality. Post-EST complications detected on CT were pancreatitis(ten patients, 1.7%) and duodenal perforation(nine patients, 1.5%). In those with pancreatitis, hospitalization after EST lasted an average of nine days in mild cases(n=3D2), 21 days in moderate(n=3D1) and 41 days in severe(n=3D7). Nine of ten patients with pancreatitis were treated conservatively, while the other, whose grade was severe, underwnet percutaneous drainage. Eight of these ten recovered;the two who died were severe grade patients, one having been treated conservatively and the other by percutaneous drain-age. In patients with duodenal perforation, hospitalization after EST lasted an average of 13 days in mild cases(n=3D2), 16 days in moderate(n=3D2) and 37 days in severe(n=3D5). Four of nine patients with duodenal perforation were treated conservatively, while the other five (severe, four;moderate, one) underwent percutaneous drainage. One patient, graded as severe, expired, but the remaining eight rocovered. Percutaneous drainage was performed mostly in severe grade cases, and among patients thus graded, only three(3/594;0.5%) died. CT is considered useful for predicting the clinical course and prognosis of complications occurring after EST.=20.

  17. Endoscopic neck surgery

    Directory of Open Access Journals (Sweden)

    Chowbey P


    Full Text Available Endoscopic surgery in the neck was attempted in 1996 for performing parathyroidectomy. A similar surgical technique was used for performing thyroidectomy the following year. Most commonly reported endoscopic neck surgery studies in literature have been on thyroid and parathyroid glands. The approaches are divided into two types i.e., the total endoscopic approach using CO2 insufflation and the video-assisted approach without CO2 insufflation. The latter approach has been reported more often. The surgical access (port placements may vary-the common sites are the neck, anterior chest wall, axilla, and periareolar region. The limiting factors are the size of the gland and malignancy. Few reports are available on endoscopic resection for early thyroid malignancy and cervical lymph node dissection. Endoscopic neck surgery has primarily evolved due to its cosmetic benefits and it has proved to be safe and feasible in suitable patients with thyroid and parathyroid pathologies. Application of this technique for approaching other cervical organs such as the submandibular gland and carotid artery are still in the early experimental phase.

  18. Sterilization of endoscopic instruments. (United States)

    Sabnis, Ravindra B; Bhattu, Amit; Vijaykumar, Mohankumar


    Sterilization of endoscopic instruments is an important but often ignored topic. The purpose of this article is to review the current literature on the sterilization of endoscopic instruments and elaborate on the appropriate sterilization practices. Autoclaving is an economic and excellent method of sterilizing the instruments that are not heat sensitive. Heat sensitive instruments may get damaged with hot sterilization methods. Several new endoscopic instruments such as flexible ureteroscopes, chip on tip endoscopes, are added in urologists armamentarium. Many of these instruments are heat sensitive and hence alternative efficacious methods of sterilization are necessary. Although ethylene oxide and hydrogen peroxide are excellent methods of sterilization, they have some drawbacks. Gamma irradiation is mainly for disposable items. Various chemical agents are widely used even though they achieve high-level disinfection rather than sterilization. This article reviews various methods of endoscopic instrument sterilization with their advantages and drawbacks. If appropriate sterilization methods are adopted, then it not only will protect patients from procedure-related infections but prevent hypersensitive allergic reactions. It will also protect instruments from damage and increase its longevity.

    Oskretkov, V I; Gur'yanov, A A; Gankov, V A; Klimova, G I; Andreasyan, A R; Balatsky, D V; Fedorov, V V; Maslikova, S A

    To analyze the results of surgical treatment of patients with benign diseases and injuries of the esophagus. We summarized the experience of different endoscopic interventions in 159 patients with various benign diseases and perforation of the esophagus. Patients with achalasia (72 cases) underwent videolaparoscopic Geller's esophagomyotomy with anterior hemiesophagofundoplication by Dor. Video-assisted thoracoscopic extirpation of the esophagus with simultaneous or delayed esophagocolo/gastroplasty was performed in 56 patients with post-ambustial cicatricial stenosis of the esophagus. Patients with esophageal perforation (14 cases) underwent videolaparoscopic transhiatal mediastinal drainage. Esophageal leiomyoma has been excised through thoracoscopic (9 cases) or laparoscopic access (4 cases). Removal of esophageal diverticulum was made via VATS-access in 4 patients. Satisfactory early and remote results were achieved in all patients with achalasia. Mortality rate was 5.4% (3 out of 56 patients) and 14.3% (2 out of 14 patients) in groups of cicatricial esophageal stenosis and esophageal perforation respectively. Sutures failure after removal of the diverticulum and leiomyoma occurred in 2 and 1 patient respectively and has been successfully cured. Endoscopic technologies allow to perform successfully complex reconstructive interventions for dysphagia in patients with cicatricial esophageal stenosis and achalasia even at late stages, to remove benign tumors and diverticula of thoracic esophagus and provide adequate drainage of posterior mediastinum in case of esophageal perforation.

  3. Olecranon extrabursal endoscopic bursectomy. (United States)

    Tu, Chen G; McGuire, Duncan T; Morse, Levi P; Bain, Gregory I


    Olecranon bursitis is a common clinical problem. It is often managed conservatively because of the high rates of wound complications with the conventional open surgical technique. Conventional olecranon bursoscopy utilizes an arthroscope and an arthroscopic shaver, removing the bursa from inside-out. We describe an extrabursal endoscopic technique where the bursa is not entered but excised in its entirety under endoscopic vision. A satisfactory view is obtained with less morbidity than the open method, while still avoiding a wound over the sensitive point of the olecranon.

    INTRODUCTION: Stercoral perforation is a rare cause of perforation. This is the first reported case where a partial eating disorder (ED) is the primary causative differential. CASE PRESENTATION: We present the case of a 17-year-old girl who presented to her local Emergency Department with a 24-h history of left-sided abdominal pain. She subsequently deteriorated and a computed tomography scan of her abdomen showed gross distension of the large bowel with a sigmoid perforation. She underwent total colectomy with end ileostomy. Histology reported stercoral perforation but normal bowel ganglia. While an inpatient she was reviewed by the Psychiatric team who were concerned she was suffering from a partial ED. CONCLUSION: This case highlights the importance of a multidisciplinary approach in optimally treating patients such as these. Aggressive medical management with involvement of a psychiatric team and dietetics addresses any underlying causative psychiatric issues and helps prevent recurrence.

In Group 2, the procedure adopted for thoracic perforations was esophagectomy. RESULTS: Operative mortality in Group 1 was 25%, and in Group 2 it was of 8.33%. CONCLUSIONS: a Cervical esophageal lesion generally presents favorable development; b surgical treatment, even when performed at a non-early phase (first 24 hours results in good evolution.

  12. Innervated digital artery perforator flap. (United States)

    Ozcanli, Haluk; Coskunfirat, Osman Koray; Bektas, Gamze; Cavit, Ali


    To describe a technique for covering defects of the fingertips: the innervated digital artery perforator (IDAP) flap. A total of 17 patients were treated with an IDAP flap. The size of the flaps varied between 2 ×1 cm and 3.5 × 2 cm. Postoperative evaluation of the patients consisted of the Semmes-Weinstein Monofilament test, static 2-point discrimination, patient satisfaction, extension loss, and an investigation into complications. All IDAP flaps survived completely, and no patients required secondary interventions. The mean follow-up period was 7 months (range, 6-10 mo). The Semmes-Weinstein monofilament test results ranged from 3.22 to 3.84. The static 2-point discrimination in the flaps ranged from 2 mm to 4 mm (mean, 3.4 mm) compared with a range of 2 mm to 3 mm (mean, 2.7 mm) on the contralateral hand. There were no joint contractures in the reconstructed fingertips, although 2 patients developed mild hook nail deformity. One patient experienced mild cold intolerance, and 1 patient exhibited mild postoperative hypersensitivity. The advantages of the IDAP flap include minimally invasive surgery; a reliable, versatile flap; and the ease of the technique for different-sized fingertip defect reconstructions with few complications. The IDAP flap may be useful in fingertip amputations when the amputated part is not suitable for replantation. Therapeutic IV. Copyright © 2013 American Society for Surgery of the Hand.

    Since the days of Albukasim in medieval Spain, natural orifices have been regarded not only as a rather repugnant source of bodily odors, fluids and excreta, but also as a convenient invitation to explore and treat the inner passages of the organism. However, surgical ingenuity needed to be matched by appropriate tools and devices. Lack of technologically advanced instrumentation was a strong deterrent during almost a millennium until recent decades when a quantum jump materialized. Endoscopic surgery is currently a vibrant and growing subspecialty, which successfully handles millions of patients every year. Additional opportunities lie ahead which might benefit millions more, however, requiring even more sophisticated apparatuses, particularly in the field of robotics, artificial intelligence, and tissue repair (surgical suturing). This is a particularly exciting and worthwhile challenge, namely of larger and safer endoscopic interventions, followed by seamless and scarless recovery. In synthesis, the future is widely open for those who use together intelligence and creativity to develop new prototypes, new accessories and new techniques. Yet there are many challenges in the path of endoscopic surgery. In this new era of robotic endoscopy, one will likely need a virtual simulator to train and assess the performance of younger doctors. More evidence will be essential in multiple evolving fields, particularly to elucidate whether more ambitious and complex pathways, such as intrathoracic and intraperitoneal surgery via natural orifice transluminal endoscopic surgery (NOTES), are superior or not to conventional techniques. © 2014 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

    Full Text Available Background. We present our experience with transnasal endoscopic dacryocystorhinostomy.Patients and methods. We treated 95 patients with lacrimal duct insufficiency from June 2000 to February 2003. The most frequent cause of nasolacrimal duct obstruction was chronic inflammation. We inserted a light probe through the inferior canalliculus to transilluminate the area of the lacrimal sac. We anaemized the region over the lacrimal sac and the attachment of the middle nasal concha and corrected nasal septum deviation were indicated. We coagulated and removed the mucosa over the transilluminated area, the bony wall and the medial portion of the lacrimal sac. After haemostasis, we placed silicone tubes through both canalliculi and fixed its ends with metallic clips. We finally introduced a Merocel tampon in the middle nasal meatus for two days. The silicone tubes remained in place for 3 to 4 months.Results. We observed no serious complications. The silicone tubes remained in place for 3 to 4 months. Follow up period ranged from 8 to 40 months. We noticed recurrence of symptoms in seven patients.Conclusions. Transnasal endoscopic DCR is a contribution to the development of endoscopic surgery technique. Its success rate is comparable to or even better than external DCR, according to other and our own study. Transnasal endoscopic DCR is a simple and successful procedure and well tolerated by the patients.

  17. Endoscopic treatment of obesity (United States)

    Swidnicka-Siergiejko, Agnieszka; Wróblewski, Eugeniusz; Dabrowski, Andrzej


    BACKGROUND: The increasing incidence of obesity and overweight among children and adolescents will be reflected by the imminent increase in the number of obese patients who require more definitive methods of treatment. There is great interest in new, safe, simple, nonsurgical procedures for weight loss. OBJECTIVE: To provide an overview of new endoscopic methods for the treatment of obesity. METHODS: An English-language literature search on endoscopic interventions, endoscopically placed devices and patient safety was performed in the MEDLINE and Cochrane Library databases. RESULTS: The literature search yielded the following weight loss methods: space-occupying devices (widely used), gastric capacity reduction, modifying gastric motor function and malabsorptive procedures. A commercially available intragastric balloon was the most commonly used device for weight loss. In specific subgroups of patients, it improved quality of life, decreased comorbidities and served as a bridge to surgery. More evidence regarding the potential benefits and safety of other commercially available intragastric balloons is needed to clarify whether they are superior to the most commonly used one. Moreover, early experiences with transoral gastroplasty, the duodenaljejunal bypass sleeve and an adjustable, totally implantable intragastric prosthesis, indicate that they may be viable options for obesity treatment. Other agents, such as botulinum toxin and a device known as the ‘butterfly’, are currently at the experimental stage. CONCLUSION: New endoscopic methods for weight loss may be valuable in the treatment of obesity; however, more clinical experience and technical improvements are necessary before implementing their widespread use.

    The ASGE Technology Committee provides reviews of existing, new, or emerging endoscopic technologies that have an impact on the practice of GI endoscopy. Evidence-based methodology is used, with a MEDLINE literature search to identify pertinent clinical studies on the topic and a MAUDE (U.S. Food and Drug Administration Center for Devices and Radiological Health) database search to identify the reported complications of a given technology. Both are supplemented by accessing the "related articles" feature of PubMed and by scrutinizing pertinent references cited by the identified studies. Controlled clinical trials are emphasized, but in many cases data from randomized, controlled trials are lacking. In such cases, large case series, preliminary clinical studies, and expert opinions are used. Technical data are gathered from traditional and Web-based publications, proprietary publications, and informal communications with pertinent vendors. Technology Status Evaluation Reports are drafted by 1 or 2 members of the ASGE Technology Committee, reviewed and edited by the committee as a whole, and approved by the Governing Board of the ASGE. When financial guidance is indicated, the most recent coding data and list prices at the time of publication are provided. For this review, the MEDLINE database was searched through February 2010 for articles related to automated endoscope reprocessors, using the words endoscope reprocessing, endoscope cleaning, automated endoscope reprocessors, and high-level disinfection. Technology Status Evaluation Reports are scientific reviews provided solely for educational and informational purposes. Technology Status Evaluation Reports are not rules and should not be construed as establishing a legal standard of care or as encouraging, advocating, requiring, or discouraging any particular treatment or payment for such treatment.

    Kim, Hyun Cheol; Yang, Dal Mo; Kim, Sang Won [Kyung Hee University Hospital at Gangdong, College of Medicine, Kyung Hee University, Department of Radiology, Seoul (Korea, Republic of); Park, Seong Jin [Kyung Hee University Hospital, College of Medicine, Kyung Hee University, Department of Radiology, Seoul (Korea, Republic of)


    To evaluate mutidetector computed tomography (MDCT) for the prediction of perforation site according to each gastrointestinal (GI) tract site and elapsed time. One hundred and sixty-eight patients who underwent MDCT before laparotomy for GI tract perforation were enrolled and allocated to an early or late lapse group based on an elapsed time of 7 h. Two reviewers independently evaluated the perforation site and assessed the following CT findings: free air location, mottled extraluminal air bubbles, focal bowel wall discontinuity, segmental bowel wall thickening, perivisceral fat stranding and localised fluid collection. The overall diagnostic accuracy was 91.07 % and 91.67 % for reviewers 1 and 2, respectively, with excellent agreement (kappa 0.86). Accuracies (98.97 % and 97.94 %) and agreements (kappa 0.894) for stomach and duodenum perforation were higher than for other perforation sites. Strong predictors of perforation at each site were: focal bowel wall discontinuity for stomach, duodenal bulb and left colon, mottled extraluminal air bubbles for retroperitoneal duodenum and right colon, and segmental bowel wall thickening for small bowel. The diagnostic accuracy was not different between the early- and late-lapse groups. MDCT can accurately predict upper GI tract perforation with high reliability. Elapsed time did not affect the accuracy of perforation site prediction. (orig.)

  1. Differentiation of Acute Perforated from Non-Perforated Appendicitis: Usefulness of High-Resolution Ultrasonography

    Energy Technology Data Exchange (ETDEWEB)

    Choi, Gyu Chang [Dept. of Radiology, Gumi Hospital, Soonchunhyang University College of Medicine, Gumi (Korea, Republic of)


    To evaluate the usefulness of high-resolution ultrasonography (US) for the differentiation of acute perforated appendicitis from non-perforated appendicitis. The high-resolution US features in 96 patients (49 males, 47 females; mean age, 33.8 years; age range, 4-80 years) with pathologically proven acute appendicitis were evaluated. The following US findings were evaluated for differentiation of acute perforated appendicitis from non-perforated appendicitis: circumferential loss of the echogenic submucosal layer, periappendiceal fluid collection, disruption of the serosal layer, asymmetrical wall thickening, maximum overall diameter > 10.5 mm, and the presence of appendicoliths. The sensitivity and specificity of the US features in the diagnosis of acute perforated appendicitis were calculated. All of the US findings, except for appendicoliths, were significantly more common in the acute perforated appendicitis group (p < 0.001). The sensitivity of circumferential loss of the echogenic submucosal layer, periappendiceal fluid collection, disruption of the serosal layer, asymmetrical wall thickening, maximum overall diameter > 10.5 mm, and the presence of appendicoliths was 85.4, 73.2, 68.3, 70.7, 80.5, and 36.6%, respectively, while the specificity was 65.5, 89.1, 96.4, 98.2, 81.8, and 80.0%, respectively. High-resolution US was found to be useful for differentiating acute perforated appendicitis from non-perforated appendicitis.

    The role of magnetic resonance imaging (MRI) in pediatric appendicitis is increasing; MRI findings predictive of appendiceal perforation have not been specifically evaluated. To assess the performance of MRI in differentiating perforated from non-perforated appendicitis. A retrospective review of pediatric patients undergoing contrast-enhanced MRI and subsequent appendectomy was performed, with surgicopathological confirmation of perforation. Appendiceal diameter and the following 10 MRI findings were assessed: appendiceal restricted diffusion, wall defect, appendicolith, periappendiceal free fluid, remote free fluid, restricted diffusion within free fluid, abscess, peritoneal enhancement, ileocecal wall thickening and ileus. Two-sample t-test and chi-square tests were used to analyze continuous and discrete data, respectively. Sensitivity and specificity for individual MRI findings were calculated and optimal thresholds for measures of accuracy were selected. Seventy-seven patients (mean age: 12.2 years) with appendicitis were included, of whom 22 had perforation. The perforated group had a larger mean appendiceal diameter and mean number of MRI findings than the non-perforated group (12.3 mm vs. 8.6 mm; 5.0 vs. 2.0, respectively). Abscess, wall defect and restricted diffusion within free fluid had the greatest specificity for perforation (1.00, 1.00 and 0.96, respectively) but low sensitivity (0.36, 0.25 and 0.32, respectively). The receiver operator characteristic curve for total number of MRI findings had an area under the curve of 0.92, with an optimal threshold of 3.5. A threshold of any 4 findings had the best ability to accurately discriminate between perforated and non-perforated cases, with a sensitivity of 82% and specificity of 85%. Contrast-enhanced MRI can differentiate perforated from non-perforated appendicitis. The presence of multiple findings increases diagnostic accuracy, with a threshold of any four findings optimally discriminating between

  6. Flexible Ultrathin Endoscope Integrated with Irrigation Suction Apparatus for Assisting Microneurosurgery. (United States)

    Otani, Naoki; Morimoto, Yuji; Fujii, Kazuya; Toyooka, Terushige; Wada, Kojiro; Mori, Kentaro


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

  7. Endoscopic indocyanine green video angiography in aneurysm surgery: an innovative method for intraoperative assessment of blood flow in vasculature hidden from microscopic view. (United States)

    Nishiyama, Yoshihisa; Kinouchi, Hiroyuki; Senbokuya, Nobuo; Kato, Tatsuya; Kanemaru, Kazuya; Yoshioka, Hideyuki; Horikoshi, Toru


    Recently, intraoperative fluorescence video angiography using indocyanine green (ICG) has been widely used in aneurysm surgery. This is a simple and useful method to confirm complete occlusion of the aneurysm lumen and preservation of blood flow in the arteries around the aneurysm. However, the observation field of ICG video angiography is limited under a microscope, making it difficult to confirm the flow in the arteries behind the parent arteries or aneurysm. The authors developed a new technique of intraoperative endoscopic ICG video angiography to assess the blood flow in perforating arteries hidden by the parent arteries or aneurysm. The endoscope emits excitation light with a wavelength of approximately 800 nm, and video images were obtained through a cut filter. The authors used this ICG fluorescence endoscope in treating 3 patients with unruptured cerebral aneurysms. During clip placement, the endoscope was inserted to confirm aneurysm occlusion. Then, ICG was intravenously administered, and the fluorescence in the vessels was observed via the endoscope as well as under the microscope. The blood flow in the perforating arteries was clearly identified, and no procedural complication occurred. The authors conclude that the technique is very useful and facilitates intraoperative real-time assessment of the patency of perforating arteries behind parent arteries or aneurysms.

  8. Endoscopic inter laminar management of lumbar disease (United States)

    Yadav, Yad Ram; Parihar, Vijay; Kher, Yatin; Bhatele, Pushp Raj


    Discectomy for lumbar disc provides faster relief in acute attack than does conservative management. Long-term results of open, microscopy-, and endoscopy-assisted discectomy are same. Early results of endoscopy-assisted surgery are better as compared to that of open surgery in terms of better visualization, smaller incision, reduced hospital stay, better education, lower cost, less pain, early return to work, and rehabilitation. Although microscopic discectomy also has comparable advantages, endoscopic-assisted technique better addresses opposite side pathology. Inter laminar technique (ILT) and trans foraminal technique (TFT) are two main endoscopic approaches for lumbar pathologies. Endoscopy-assisted ILT can be performed in recurrent, migrated, and calcified discs. All lumbar levels including L5-S1 level, intracanalicular, foraminal disc, lumbar canal and lateral recess stenosis, multiple levels, and bilateral lesions can be managed by ILT. Migrated, calcified discs, L5-S1 pathology, lumbar canal, and lateral recess stenosis can be better approached by ILT than by TFT. Most spinal surgeons are familiar with anatomy of ILT. It can be safely performed in foramen stenosis and in uncooperative and anxious patients. There is less risk of exiting nerve root damage, especially in short pedicles and in presence of facet osteophytes as compared to TFT. On the other hand, ILT is more invasive than TFT with more chances of perforations of the dura matter, pseudomeningocele formation, and cerebrospinal fluid fistula in early learning curve. Obtaining microsurgical experience, attending workshops, and suitable patient selection can help shorten the learning curve. Once adequate skill is acquired, this procedure is safe and effective. The surgeon must be prepared to convert to an open procedure, especially in early learning curve. Spinal endoscopy is likely to achieve more roles in future. Endoscopy-assisted ILT is a safer alternative to the microscopic technique. PMID

    Voorbrood, C E H; Burgmans, J P J; Clevers, G J; Davids, P H P; Verleisdonk, E J M M; van Dalen, T


    Inguinal hernias are common in elderly males. We addressed outcome following totally extraperitoneal (TEP) hernia repair in patients older than 70 years. We prospectively collected data of patients >70 years with a unilateral or bilateral inguinal hernia operated in our hospital between January 2005 and January 2010 using the TEP technique. A total of 429 patients underwent TEP hernia repair under general anaesthesia, mostly men (n = 405; 94.4%). Median age was 74 years (range 70-89). The mean pre-operative pain score was 3.7 (SD ± 2.5). Ninety-four percent of patients had an ASA score of 1 or 2. Three hundred thirty-six patients underwent a unilateral repair (78%). The conversion rate to an anterior procedure was 0.7 % (n = 3). In 8 patients (1.9%), intra-operative complications occurred, and the postoperative course was complicated in 3 patients (0.7 %). Severe complications attributable to the endoscopic approach occurred in 6 patients (1.4%): a bladder injury (n = 5) and a trocar-induced bowel perforation (n = 1). The mean postoperative pain score after 6 weeks was 1.6 (SD ± 1.2). Patients were able to resume their daily activities after a median of 7 days (range 1-42). Totally, extraperitoneal endoscopic inguinal hernia repair in elderly patients is associated with low overall complication rates and a fast recovery. In a small proportion of patients, severe complications occur attributable to the endoscopic approach.

  10. Double peptic perforation: Report of a rare case

    Atul K. Sharma


    Full Text Available Perforation peritonitis is the most common surgery performed in an emergency. Upper gastrointestinal tract perforation is more common than lower gastrointestinal perforation. Multiple peptic perforations in an individual are a relatively rare entity, with fewer than 10 cases reported in the literature. The factor that contributes the most for the occurrence of multiple peptic perforations is analgesic and steroid abuse. Herein, we report a rare case of double peptic perforation in a middle-aged man with history of analgesic use for 18 months.

  11. Transaxillary Endoscopic Breast Augmentation

    Directory of Open Access Journals (Sweden)

    Hyung-Bo Sim


    Full Text Available The axillary technique is the most popular approach to breast augmentation among Korean women. Transaxillary breast augmentation is now conducted with sharp electrocautery dissection under direct endoscopic vision throughout the entire process. The aims of this method are clear: both a bloodless pocket and a sharp non-traumatic dissection. Round textured or anatomical cohesive gel implants have been used to make predictable well-defined inframammary creases because textured surface implants demonstrated a better stability attributable to tissue adherence compared with smooth surface implants. The axillary endoscopic technique has greatly evolved, and now the surgical results are comparable to those with the inframammary approach. The author feels that this technique is an excellent choice for young patients with an indistinct or absent inframammary fold, who do not want a scar in the aesthetic unit of their chest.

    Full Text Available Endoscopic sphincterotomy (EST is a treatment of choice for stone extraction and is now most frequently used. The study was to compare the efficacy of endoscopic papillary large balloon dilatation (EPLBD and endoscopic sphincterotomy (EST for common bile duct stone removal. Trials comparing the effects between EPLBD and EST treatment were searched according to the study protocol. Overall stone removal rate, complete removal rate in 1st session, treatment duration, mechanical lithotripsy using rate, and overall complication rate were compared using risk ratio (RR and mean difference (MD and their 95% confidence interval (CI via RevMan 5.2 software. For overall stone removal rate, two therapies showed similar effect, but EPLBD showed better overall stone removal rate for stone >10 mm in diameter. For complete stone removal rate in 1st session, no difference was found, even for those with stone >10 mm in diameter; EPLBD showed longer treatment duration, higher mechanical lithotripsy using rate obvious overall complications rate, and more serious bleeding, whereas there were no significant differences for perforation, hyperamylasemia, pancreatitis, and cholecystitis/cholangitis. EPLBD showed better efficacy in certain conditions compared to EST, however with shortcomings, such as more duration, higher mechanical lithotripsy using rate, more serious overall complications rate, and bleeding.

  13. Instrumentation: endoscopes and equipment. (United States)

    Gaab, Michael R


    The technology and instrumentation for neuroendoscopy are described: endoscopes (principles, designs, applications), light sources, instruments, accessories, holders, and navigation. Procedures for cleaning, sterilizing, and storing are included. The description is based on the author's own technical development and neuroendoscopic experience, published technology and devices, and publications on endoscopic surgery. The main work horses in neuroendoscopy are rigid glass rod endoscopes (Hopkins optics) due to the optical quality, which allows full high-definition video imaging, different angles of view, and autoclavability, which is especially important in neuroendoscopy due to the risk of Creutzfeldt-Jakob disease infection. Applications are endoscopy assistance to microsurgery, stand-alone endoscopy controlled approaches such as transnasal skull base, ventriculoscopy, and cystoscopy in the cranium. Rigid glass rod optics are also applicable in spinal endoscopy and peripheral nerve decompression using special tubes and cannulas. Rigid minifiberoptics with less resolution may be used in less complex procedures (ventriculoscopy, cystoscopy, endoscopy assistance with pen-designs) and have the advantages of smaller diameters and disposable designs. Flexible fiberoptics are usually used in combination with rigid scopes and can be steered, e.g. through the ventricles, in spinal procedures for indications including syringomyelia and multicystic hydrocephalus. Upcoming flexible chip endoscopes ("chip-in-the-tip") may replace flexible fiberoptics in the future, offering higher resolution and cold LED-illumination, and may provide for stereoscopic neuroendoscopy. Various instruments (mechanical, coagulation, laser guides, ultrasonic aspirators) and holders are available. Certified methods for cleaning and sterilization, with special requirements in neuroapplications, are important. Neuroendoscopic instrumentation is now an established technique in neurosurgical practice and

  14. Endoscopic tissue diagnosis of cholangiocarcinoma.

    LENUS (Irish Health Repository)

    Harewood, Gavin C


    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.

  15. [Endoscopic Resection of Sporadic Non-ampullary Duodenal Neoplasms: A Single Center Study]. (United States)

    Nam, Yoon Jeong; Lee, Si Hyung; Kim, Kyeong Ok; Jang, Byung Ik; Kim, Tae Nyeun; Kim, Yong Jin


    Sporadic non-ampullary duodenal neoplasms are rare and optimal treatment for these lesions remains undefined. Endoscopic resection of duodenal neoplasms is widely used recently and it is an alternative treatment strategy to surgical excision. This study aimed to evaluate the safety and efficacy of endoscopic resection of duodenal neoplasms and to determine its outcomes. Patients who underwent endoscopic resection for non-ampullary duodenal neoplasms between January 2005 and December 2014 were analyzed retrospectively. Data including size, morphology, histology, location and endoscopic procedural technique were reviewed. The main outcome measurements were success rate, complication, recurrence and follow-up assessments. The study included 33 patients with duodenal neoplasms. The mean size of resected lesion was 8.58 mm. The results of histologic examination were as follows: 23 (69.7%) adenomas, 2 (6.1%) adenocarcinoma, 3 (9.1%) Brunner's gland tumor and 3 (9.1%) neuroendocrine tumor. Tubular adenoma was the most common type (63.6%) of non-ampullary duodenal neoplasms. Eighteen (54.5%) lesions were found in the second portion of the duodenum, and 10 (30.3%) lesions on bulb and 3 (9.1%) lesions on superior duodenal angle. Of the 33 cases, 32 (97.0%) were managed by endoscopic mucosal resection technique during a single session and one case was managed by endoscopic submucosal dissection (ESD). One episode of perforation occurred after ESD. During a median follow-up period of 5.76 months, recurrence was observed in only one case of in a patient with tubular adenoma. Endoscopic resection of duodenal neoplasm is a safe and effective treatment modality that can replace surgical resection in many cases. Careful endoscopic follow-up is essential to manage recurrence or residual lesions.

    Papachristou, Georgios I; Takahashi, Naoki; Chahal, Prabhleen; Sarr, Michael G; Baron, Todd H


    Experience with minimal access, transoral/transmural endoscopic drainage/debridement of walled-off pancreatic necrosis (WOPN) after necrotizing pancreatitis is limited. We sought to determine outcome using this technique. Retrospective analysis. From 1998 to 2006, 53 patients underwent transoral/transmural endoscopic drainage/debridement of sterile (27, 51%) and infected (26, 49%) WOPN. Intervention was performed a median of 49 days (range, 20-300 days) after onset of acute necrotizing pancreatitis. A median of 3 endoscopic procedures/patient (range, 1-12) were performed. Twenty-one patients (40%) required concurrent radiologic-guided catheter drainage of associated or subsequent areas of peripancreatic fluid and/or WOPN. Twelve patients (23%) required open operative intervention a median of 47 days (range, 5-540) after initial endoscopic drainage/debridement, due to persistence of WOPN (n = 3), recurrence of a fluid collection (n = 2), cutaneous fistula formation (n = 2), or technical failure, persistence of pancreatic pain, colonic obstruction, perforation, and flank abscess (n = 1 each). Final outcome after initial endoscopic intervention (median, 178 days) revealed successful endoscopic therapy in 43 (81%) and persistence of WOPN in 10 (19%). Preexistent diabetes mellitus, size of WOPN, and extension of WOPN into paracolic gutter were significant predictive factors for need of subsequent open operative therapy. Successful resolution of symptomatic, sterile, and infected WOPN can be achieved using a minimal access endoscopic approach. Adjuvant percutaneous drainage is necessary in up to 40% of patients, especially when WOPN extends to paracolic gutters or pelvis. Operative intervention for failed endoscopic treatment is required in about 20% of patients.

  17. Congenital breast deformity reconstruction using perforator flaps. (United States)

    Gautam, Abhinav K; Allen, Robert J; LoTempio, Maria M; Mountcastle, Timothy S; Levine, Joshua L; Allen, Robert J; Chiu, Ernest S


    Congenital breast deformities such as Poland syndrome, unilateral congenital hypoplasia, tuberous breast anomaly, and amastia pose a challenging plastic surgical dilemma. The majority of patients are young, healthy individuals who seek esthetic restoration of their breast deformities. Currently, both implant and autologous reconstructive techniques are used. This study focuses on our experience with congenital breast deformity patients who underwent reconstruction using a perforator flap. From 1994 to 2005, a retrospective chart review was performed on women who underwent breast reconstruction using perforator flaps to correct congenital breast deformities and asymmetry. Patient age, breast deformity type, perforator flap type, flap volume, recipient vessels, postoperative complications, revisions, and esthetic results were determined. Over an 11-year period, 12 perforator flaps were performed. All cases were for unilateral breast deformities. The patients ranged from 16 to 43 years of age. Six patients had undergone previous correctional surgeries. Eight (n = 8) flaps were used for correction of Poland syndrome and its associated chest wall deformities. Four (n = 4) flaps were used for correction of unilateral breast hypoplasia. In all cases, the internal mammary vessels were the recipient vessels of choice. No flaps were lost. No vein grafts were used. All patients were discharged on the fourth postoperative day. Complications encountered included seroma, hematoma, and nipple malposition. Revisional surgery was performed in 30% of the cases. Esthetic results varied from poor to excellent. Perforator flaps are an acceptable choice for patients with congenital breast deformities seeking autologous breast reconstruction. Deep inferior epigastric artery (DIEP) or superficial inferior epigastric artery (SIEA) flaps are performed when adequate abdominal tissue is available; however, many young patients have inadequate abdominal tissue, thus a GAP flap can be used

  18. Fast track pathway for perforated appendicitis. (United States)

    Frazee, Richard; Abernathy, Stephen; Davis, Matthew; Isbell, Travis; Regner, Justin; Smith, Randall


    Perforated appendicitis is associated with an increased morbidity and length of stay. "Fast track" protocols have demonstrated success in shortening hospitalization without increasing morbidity for a variety of surgical processes. This study evaluates a fast track pathway for perforated appendicitis. In 2013, a treatment pathway for perforated appendicitis was adopted by the Acute Care Surgery Service for patients having surgical management of perforated appendicitis. Interval appendectomy was excluded. Patients were treated initially with intravenous antibiotics and transitioned to oral antibiotics and dismissed when medically stable and tolerating oral intake. A retrospective review of patients managed on the fast track pathway was undertaken to analyze length of stay, morbidity, and readmissions. Thirty-four males and twenty-one females with an average age of 46.8 years underwent laparoscopic appendectomy for perforated appendicitis between January 2013 and December 2014. Pre-existing comorbidities included hypertension 42%, diabetes mellitus 11%, COPD 5% and heart disease 2%. No patient had conversion to open appendectomy. Average length of stay was 2.67 days and ranged from 1 to 12 days (median 2 days). Postoperative morbidity was 20% and included abscess (6 patients), prolonged ileus (3 patients), pneumonia (1 patient), and congestive heart failure (1 patient). Five patients were readmitted for abscess (3 patients), congestive heart failure (1 patient), and pneumonia (1 patient). A fast track pathway for perforated appendicitis produced shorter length of stay and acceptable postoperative morbidity and readmission. This offers the potential for significant cost savings over current national practice patterns. Copyright © 2016 Elsevier Inc. All rights reserved.

  19. Late presenting Bochdalek hernia with gastric perforation. (United States)

    Ozkan, Aybars; Bozkurter Cil, Asudan Tugce; Kaya, Murat; Etcioglu, Inci; Okur, Mesut


    Late-onset congenital diaphragmatic hernias that give symptoms beyond the neonatal period are rare and are difficult to diagnose. The diagnosis is usually made in case of complications such as intestinal obstruction, strangulation, and perforation, which further necessitate immediate surgical repair. The case of a 5-year-old child presenting with acute respiratory distress with gastric strangulation and perforation secondary to Bochdalek hernia is reported here. Although presentation in the latter ages is less common, congenital diaphragmatic hernia should be included in the differential diagnosis of respiratory distress in children. Symptoms and diagnostic tools should truly be interpreted. Gastrointestinal complications must urgently be recognized, and early surgical intervention must be performed.

  20. Right-Sided Sigmoid Diverticular Perforation

    Directory of Open Access Journals (Sweden)

    Andrew Little


    Full Text Available Diverticulosis is a common disorder among geriatric patients, of whom 10% to 25% go on to develop diverticulitis. Known complications of diverticulitis include formation of phlegmon, fistula, bowel obstruction, bleeding, perforation, and colonic abscess. A less common complication is perforation with formation of an extra-abdominal necrotizing abscess. This case is a report of an 83-year-old female who presented to the emergency department with a necrotizing abdominal wall abscess secondary to right-sided diverticular microperforation.

  1. Chronic Cervical Perforation by an Intrauterine Device

    Directory of Open Access Journals (Sweden)

    Semra Oruç Koltan


    Full Text Available The intrauterine device (IUD is a widely used, highly effective method of birth control. Uterine perforation is a rare yet serious complication and is usually seen during insertion of the IUD. A regular examination is necessary for follow-up. We present a patient with an IUD that had perforated the cervix. The diagnosis was made during routine gynecological examination, and the patient was treated in a timely manner before any complications such as ectopic pregnancy, intrauterine pregnancy, infection or irreversible harm to the cervix arose. This case stresses the importance of regular visits to maintain health and diagnose possible adverse effects of intrauterine contraceptive methods.

  2. Pneumoperitoneum Secondary to Spontaneously Perforated Pyometra

    Directory of Open Access Journals (Sweden)

    Benjamin A. Raymond


    Full Text Available Pyometra, by definition, is a collection of purulent fluid within the uterine cavity. Incidence has been estimated to range from 0.1% to 0.5%. Typically, this is linked to postmenopausal women; however, it has been linked to premenopausal women with concordant use of intrauterine devices. Based on our knowledge, there have been less than 50 recorded cases reported in the English literature regarding perforation of pyometra resulting in acute abdomen and fewer than 25 resulting in pneumoperitoneum. We report a patient who was evaluated for diffuse peritonitis caused by perforated pyometra who was successfully treated with surgical intervention.

    Nasogastric tube-feeding often is necessary in the treatment of chronically ill patients. The disadvantage (irritation of the hypopharynx, dislocation, stigma) can be avoided by the percutaneous endoscopic gastrostomy (PEG). In childhood there is only limited experience with this techniques. We report about 89 children with PEG. Indications were central dysphagia (67), dystrophy caused by chronic renal failure or congenital heart disease (15), application of special diets (6) and gastric volvulus (1). The endoscopy was done in sedation. The PEG was placed in the stomach (73) or duodenum (16). 14 Complications were observed: inflammation at the insertion site (2), perforation (2, healing under conservative treatment), dislocation of the duodenal part into the stomach or occlusion (6) and distraction of the retention disk (4). There were no procedures-related deaths. The mean duration of the PEG was more than 1 year. The affected persons were very pleased with the efficacy of this treatment. In all patients (including infants) requiring long-term tube-feeding the option of a PEG should be taken into consideration. In our experience the PEG is associated with a low rate of complications and provides a major improvement for children who are dependent on tube feeding.

    Gallbladder perforation is a rare but severe complication of acute cholecystitis with a high morbidity and mortality. Clinical symptoms of gallbladder perforation are usually unspecific, and the differentiation from uncomplicated cholecystitis can be challenging. Early diagnosis of gallbladder perforation and immediate surgical intervention are of crucial importance and might reduce mortality rates and prolonged postoperative hospital stays. We present a case of gallbladder perforation in a 59-year-old man with preoperatively diagnosed by ultrasonography.

    Nishida, Tsutomu; Tsujii, Masahiko; Kato, Motohiko; Hayashi, Yoshito; Akasaka, Tomofumi; Iijima, Hideki; Takehara, Tetsuo


    Early detection of early gastric cancer (EGC) is important to improve the prognosis of patients with gastric cancer. Recent advances in endoscopic modalities and treatment devices, such as image-enhanced endoscopy and high-frequency generators, may make endoscopic treatment, such as endoscopic submucosal dissection, a therapeutic option for gastric intraepithelial neoplasia. Consequently, short-term outcomes of endoscopic resection (ER) for EGC have improved. Therefore, surveillance with endoscopy after ER for EGC is becoming more important, but how to perform endoscopic surveillance after ER has not been established, even though the follow-up strategy for more advanced gastric cancer has been outlined. Therefore, a surveillance strategy for patients with EGC after ER is needed.

  18. Determination of the Fundamental Frequency of Perforated Rectangular Plates: Concentrated Negative Mass Approach for the Perforation

    Directory of Open Access Journals (Sweden)

    Kiran D. Mali


    Full Text Available This paper is concerned with a vibration analysis of perforated rectangular plates with rectangular perforation pattern of circular holes. The study is particularly useful in the understanding of the vibration of sound absorbing screens, head plates, end covers, or supports for tube bundles typically including tube sheets and support plates used in the mechanical devices. An energy method is developed to obtain analytical frequencies of the perforated plates with clamped edge, support conditions. Perforated plate is considered as plate with uniformly distributed mass. Holes are considered as concentrated negative masses. The analytical procedure using the Galerkin method is adopted. The deflected surface of the plate is approximated by the cosine series which satisfies the boundary conditions. Finite element method (FEM results have been used to illustrate the validity of the analytical model. The comparisons show that the analytical model predicts natural frequencies reasonably well for holes of small size.

    ArkalVittal Hegde


    Full Text Available Many new types of breakwaters have been constructed of lateto fulfill the ever increasing demand of marine traffic. The quarter circle breakwater (QBW is a recent type of breakwater developed on the lines of an earlier semicircular breakwater (SBW. QBW may be without perforations, seaside perforated or both sides perforated. A series of laboratory experiments were conducted in a two dimensional monochromatic wave flume on an emerged seaside perforated non-overtopping quarter circle breakwater model to study its stability against sliding. The scale of the model was 1:30. A range of incident wave heights (Hi and wave periods (T were generated in the flume simulating the wave climate off Mangaluru coast in the Karnataka State of India. The experimental data so collected was analyzed to understand the variation of the non-dimensional stability parameter with incident wave steepness for different values of dimensionless depth parameter In the end a nomogram was developed for computing the sliding stability of the breakwater.

    This letter introduces a modified design of membrane-type acoustic metamaterials (MAMs) with a ring mass and a perforation so that an airflow through the membrane is enabled. Simplified analytical investigations of the perforated MAM (PMAM) indicate that the perforation introduces a second anti-resonance, where the effective surface mass density of the PMAM is much higher than the static value. The theoretical results are validated using impedance tube measurements, indicating good agreement between the theoretical predictions and the measured data. The anti-resonances yield high low-frequency sound transmission loss values with peak values over 25 dB higher than the corresponding mass-law. - Highlights: • A new membrane-type acoustic metamaterial exhibiting negative density is presented. • The metamaterial design contains a ring mass with a perforation through the membrane. • The sound transmission loss exhibits narrow-band peaks much higher than the mass-law. • The emergence of the peaks is explained using a simple theoretical model. • Impedance tube measurements are used to validate the theoretical predictions.

  11. Acute phlegmonous gastritis complicated by delayed perforation. (United States)

    Min, Sun Young; Kim, Yong Ho; Park, Won Seo


    Here, we report on a case of acute phlegmonous gastritis (PG) complicated by delayed perforation. A 51-year-old woman presented with severe abdominal pain and septic shock symptoms. A computed tomography scan showed diffuse thickening of the gastric wall and distention with peritoneal fluid. Although we did not find definite evidence of free air on the computed tomography (CT) scan, the patient's clinical condition suggested diffuse peritonitis requiring surgical intervention. Exploratory laparotomy revealed a thickened gastric wall with suppurative intraperitoneal fluid in which Streptococcus pyogenes grew. There was no evidence of gastric or duodenal perforation. No further operation was performed at that time. The patient was conservatively treated with antibiotics and proton pump inhibitor, and her condition improved. However, she experienced abdominal and flank pain again on postoperative day 10. CT and esophagogastroduodenoscopy showed a large gastric ulcer with perforation. Unfortunately, although the CT showed further improvement in the thickening of the stomach and the mucosal defect, the patient's condition did not recover until a week later, and an esophagogastroduodenoscopy taken on postoperative day 30 showed suspected gastric submucosal dissection. We performed total gastrectomy as a second operation, and the patient recovered without major complications. A pathological examination revealed a multifocal ulceration and necrosis from the mucosa to the serosa with perforation.

  12. Jejunal Diverticular Perforation due to Enterolith

    Directory of Open Access Journals (Sweden)

    Ronaldo Nonose


    Full Text Available Jejunal diverticulosis is a rare entity with variable clinical and anatomical presentations. Although there is no consensus on the management of asymptomatic jejunal diverticular disease, some complications are potentially life-threatening and require early surgical treatment. Small bowel perforation secondary to jejunal diverticulitis by enteroliths is rare. The aim of this study was to report a case of small intestinal perforation caused by a large jejunal enterolith. An 86-year-old woman was admitted with signs of diffuse peritonitis. After initial fluid recovery the patient underwent emergency laparotomy. The surgery showed that she had small bowel diverticular disease, mainly localized in the proximal jejunum. The peritonitis was due to intestinal perforation caused by an enterolith 12 cm in length, localized inside one of these diverticula. The intestinal segment containing the perforated diverticulum with the enterolith was removed and an end-to-end anastomosis was done to reconstruct the intestinal transit. The patient recovered well and was discharged from hospital on the 5th postoperative day. There were no signs of abdominal pain 1 year after the surgical procedure. Although jejunal diverticular disease with its complications, such as formation of enteroliths, is difficult to suspect in patients with peritonitis, it should be considered as a possible source of abdominal infection in the elderly patient when more common diagnoses have been excluded.

  18. Rinsability of Orthophthalaldehyde from Endoscopes

    Directory of Open Access Journals (Sweden)

    Norman Miner


    Full Text Available Orthophthalaldehyde high level disinfectants are contraindicated for use with urological instruments such as cystoscopes due to anaphylaxis-like allergic reactions during surveillance of bladder cancer patients. Allergic reactions and mucosal injuries have also been reported following colonoscopy, laryngoscopy, and transesophageal echocardiography with devices disinfected using orthophthalaldehyde. Possibly these endoscopes were not adequately rinsed after disinfection by orthophthalaldehyde. We examined this possibility by means of a zone-of-inhibition test, and also a test to extract residues of orthophthalaldehyde with acetonitrile, from sections of endoscope insertion tube materials, to measure the presence of alkaline glutaraldehyde, or glutaraldehyde plus 20% w/w isopropanol, or ortho-phthalaldehyde that remained on the endoscope materials after exposure to these disinfectants followed by a series of rinses in water, or by aeration overnight. Zones of any size indicated the disinfectant had not been rinsed away from the endoscope material. There were no zones of inhibition surrounding endoscope materials soaked in glutaraldehyde or glutaraldehyde plus isopropanol after three serial water rinses according to manufacturers' rinsing directions. The endoscope material soaked in orthophthalaldehyde produced zones of inhibition even after fifteen serial rinses with water. Orthophthalaldehyde was extracted from the rinsed endoscope material by acetonitrile. These data, and other information, indicate that the high level disinfectant orthophthalaldehyde, also known as 1,2-benzene dialdehyde, cannot be rinsed away from flexible endoscope material with any practical number of rinses with water, or by drying overnight.

The aim of the present study is to compare the safety and outcomes of endoscopic and open resection of small gastric GISTs. From May 2010 to March 2014, a total of 90 small gastric GIST patients were enrolled in the present study, including 40 patients who underwent surgical resection and 50 patients who underwent endoscopic resection. The clinicopathological characteristics, resection-related factors, and clinical outcomes were recorded and analyzed. The clinicopathological characteristics were comparable between the two groups except for tumor location and DOG-1 expression. Compared with the surgical resection group, the operation time was shorter (P = .000, blood loss was less (P = .000, pain intensity was lower (P < .05, duration of first flatus and defecation was shorter (P < .05, and medical cost of hospitalization was lower (P = .027 in the endoscopic resection group. The complications and postoperative hospital stay were comparable between the two groups. No in situ recurrence or liver metastasis was observed during follow-up. Endoscopic resection of small gastric GISTs is safe and feasible compared with surgical resection, although perforation could not be totally avoided during and after resection. The clinical outcome of endoscopic resection is also favorable.

    Full Text Available ObjectiveTo evaluate the feasibility, safety, and follow-up results of endoscopic ligation with nylon snares for adenoma of the major duodenal papilla. MethodsTwenty-three patients with adenoma of the major papilla who were treated in our hospital from January 2012 to June 2014 were enrolled as subjects. All patients had biliary and pancreatic duct stents placed by endoscopic cholangiopancreatography, followed by complete ligation of tumors with nylon snares. Endoscopic follow-up evaluation of recurrence was performed regularly. ResultsAll patients had biliary and pancreatic duct stents successfully placed and tumors successfully ligated with nylon snares in their first surgery. Endoscopic reexamination at two weeks after surgery showed that tumors were removed in all patients. Postoperative complications, cholangitis and pancreatitis, were found in one (4.3% and two (8.7% patients, respectively, and there were no bleeding, perforation, or death. A follow-up of more than one year in all patients showed that two patients had local recurrence of adenoma. ConclusionEndoscopic ligation with nylon snares is a safe and effective approach for treating adenoma of the major duodenal papilla.

  4. Experimental evaluation of photocrosslinkable chitosan hydrogel as injection solution for endoscopic resection. (United States)

    Ishizuka, T; Ishihara, M; Aiko, S; Nogami, Y; Nakamura, S; Kanatani, Y; Kishimoto, S; Hattori, H; Horio, T; Tanaka, Y; Maehara, T


    Saline as an injection solution for endoscopic resection techniques has several disadvantages such as a short-lasting effect leading to a potentially higher risk of bleeding and perforation. The new substance of photocrosslinkable chitosan hydrogel in a DMEM/F12 medium (PCH) can be converted into an insoluble hydrogel by ultraviolet irradiation for 30 s, and was evaluated in two sets of animal experiments. 18 pigs were used in the two parts of the study. First, mucosal resections were done with either PCH or hypertonic saline; the effects of both agents on wound healing were examined endoscopically and histologically. Second, in vivo degradation of PCH was examined using six pig stomachs. PCH injection led to a longer-lasting elevation with clearer margins, compared with hypertonic saline, thus enabling precise endoscopic submucosal dissection (ESD) along the margins of the elevated mucosa. The endoscopic appearance after ESD was similar in both groups. PCH biodegradation was completed within 8 weeks according to endoscopic and histologic analyses. PCH is a promising agent for submucosal injection prior to various techniques of endoresection. It should be evaluated in clinical trials after biocompatibility testing for PCH is completed.

    Nishide, N; Ono, H; Kakushima, N; Takizawa, K; Tanaka, M; Matsubayashi, H; Yamaguchi, Y


    Little information exists regarding the optimal treatment of early gastric cancer (EGC) in a remnant stomach or gastric tube. The aim of this study was to assess the feasibility and clinical outcomes of endoscopic submucosal dissection (ESD) for EGC in a remnant stomach and gastric tube. Between September 2002 and December 2009, ESD was performed in 62 lesions in 59 patients with EGC in a remnant stomach (48 lesions) or gastric tube (14 lesions). Clinicopathological data were retrieved retrospectively to assess the en bloc resection rate, complications, and outcomes. Treatment results were assessed according to the indications for endoscopic resection, and were compared with those of ESD performed in a whole stomach during the same study period. The en bloc resection rates for lesions within the standard and expanded indication were 100 % and 93 %, respectively. Postoperative bleeding occurred in five patients (8 %). The perforation rate was significantly higher (18 %, 11 /62) than that of ESD in a whole stomach (5 %, 69 /1479). Among the perforation cases, eight lesions involved the anastomotic site or stump line, and ulcerative changes were observed in five lesions. The 3-year overall survival rate was 85 %, with eight deaths due to other causes and no deaths from gastric cancer. A high en bloc resection rate was achieved by ESD for EGC in a remnant stomach or gastric tube; however, this procedure is still technically demanding due to the high complication rate of perforation. © Georg Thieme Verlag KG Stuttgart · New York.

  6. Endoscopic management of gastric varices using a detachable snare and simultaneous endoscopic sclerotherapy and O-ring ligation. (United States)

    Yoshida, T; Harada, T; Shigemitsu, T; Takeo, Y; Miyazaki, S; Okita, K


    Cyanoacrylate injection is highly effective and is regarded as the treatment of choice in bleeding gastric varices in Europe, but intravenous injection of cyanoacrylate is not allowed in the USA and Japan because it may cause embolisms in other organs. Accordingly, we developed a new endoscopic combined treatment of endoscopic management of gastric varices using a detachable snare (EVLs) and simultaneous endoscopic sclerotherapy and O-ring ligation (EISL) (i.e. EVLs + EISL), and we prospectively evaluated its efficacy and safety. Gastric varices were ligated with the loop of a detachable snare that opened to a diameter of 4 cm (EVLs). Then the residual varices around the ligated portion were sclerosed by ethanolamine oleate and the injected vessel was ligated using a pneumo-activated EVL device (EISL). The EVLs + EISL was performed in 35 patients: on an emergency basis in eight patients, on an elective basis in six patients and as primary prophylaxis in 21 patients. Liver function was classified as Child-Pugh class A in 12 patients, class B in 12 patients and class C in 11 patients. Endoscopic disappearance of gastric varices was obtained in 97.1% of the patients and they regressed in all patients. Haemostasis was achieved in all eight emergency cases. The 2-year cumulative non-recurrence rate was 85%, the 2-year cumulative non-bleeding rate was 92% and the 2-year cumulative survival was 80%. No patients died of bleeding from gastric varices. There were no serious short-term complications, such as haemorrhage, gastro-oesophageal perforation, ileus, or renal impairment. Combined EVLs + EISL appears to be a useful treatment for gastric varices due to its safety and good clinical outcome.

  7. [Endoscopic vacuum-assisted closure]. (United States)

    Wedemeyer, J; Lankisch, T


    Anastomotic leakage in the upper and lower intestinal tract is associated with high morbidity and mortality. Within the last 10 years endoscopic treatment options have been accepted as sufficient treatment option of these surgical complications. Endoscopic vacuum assisted closure (E-VAC) is a new innovative endoscopic therapeutic option in this field. E-VAC transfers the positive effects of vacuum assisted closure (VAC) on infected cutaneous wounds to infected cavities that can only be reached endoscopically. A sponge connected to a drainage tube is endoscopically placed in the leakage and a continuous vacuum is applied. Sponge and vacuum allow removal of infected fluids and promote granulation of the leakage. This results in clean wound grounds and finally allows wound closure. Meanwhile the method was also successfully used in the treatment of necrotic pancreatitis.

  8. Mortality risk factor analysis in colonic perforation: would retroperitoneal contamination increase mortality in colonic perforation? (United States)

    Yoo, Ri Na; Kye, Bong-Hyeon; Kim, Gun; Kim, Hyung Jin; Cho, Hyeon-Min


    Colonic perforation is a lethal condition presenting high morbidity and mortality in spite of urgent surgical treatment. This study investigated the surgical outcome of patients with colonic perforation associated with retroperitoneal contamination. Retrospective analysis was performed for 30 patients diagnosed with colonic perforation caused by either inflammation or ischemia who underwent urgent surgical treatment in our facility from January 2005 to December 2014. Patient characteristics were analyzed to find risk factors correlated with increased postoperative mortality. Using the Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM) audit system, the mortality and morbidity rates were estimated to verify the surgical outcomes. Patients with retroperitoneal contamination, defined by the presence of retroperitoneal air in the preoperative abdominopelvic CT, were compared to those without retroperitoneal contamination. Eight out of 30 patients (26.7%) with colonic perforation had died after urgent surgical treatment. Factors associated with mortality included age, American Society of Anesthesiologists (ASA) physical status classification, and the ischemic cause of colonic perforation. Three out of 6 patients (50%) who presented retroperitoneal contamination were deceased. Although the patients with retroperitoneal contamination did not show significant increase in the mortality rate, they showed significantly higher ASA physical status classification than those without retroperitoneal contamination. The mortality rate predicted from Portsmouth POSSUM was higher in the patients with retroperitoneal contamination. Patients presenting colonic perforation along with retroperitoneal contamination demonstrated severe comorbidity. However, retroperitoneal contamination was not found to be correlated with the mortality rate.

    Decristoforo, Petra; Kaltseis, Josef; Fritz, Andreas; Edlinger, Michael; Posch, Wilfried; Wilflingseder, Doris; Lass-Flörl, Cornelia; Orth-Höller, Dorothea


    Several outbreaks of severe infections due to contamination of gastrointestinal (GI) endoscopes, mainly duodenoscopes have been described previously. The rate of microbial endoscope contamination is varying dramatically in literature. Thus, 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- and molecular-based analyses. The contamination rate of GI endoscopes was 1.3-4.6% according to 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 in phase II. The most commonly identified indicator organism was Pseudomonas spp., mainly P. 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 to microbial contamination of the last rinsing water, mainly with Pseudomonas spp. In the present study the contamination rate of endoscopes was low compared to results from other European countries, possibly due to high quality of endoscope reprocessing, drying and storage.

  10. Endoscopic egomotion computation (United States)

    Bergen, Tobias; Ruthotto, Steffen; Rupp, Stephan; Winter, Christian; Münzenmayer, Christian


    Computer assistance in Minimally Invasive Surgery is a very active field of research. Many systems designed for Computer Assisted Surgery require information about the instruments' positions and orientations. Our main focus lies on tracking a laparoscopic ultrasound probe to generate 3D ultrasound volumes. State-of-the-art tracking methods such as optical or electromagnetic tracking systems measure pose with respect to a fixed extra-body coordinate system. This causes inaccuracies of the reconstructed ultrasound volume in the case of patient motion, e.g. due to respiration. We propose attaching an endoscopic camera to the ultrasound probe and calculating the camera motion from the video sequence with respect to the organ surface. We adapt algorithms developed for solving the relative pose problem to recreate the camera path during the ultrasound sweep over the organ. By this image-based motion estimation camera motion can only be determined up to an unknown scale factor, known as the depth-speed-ambiguity. We show, how this problem can be overcome in the given scenario, exploiting the fact, that the distance of the camera to the organ surface is fixed and known. Preprocessing steps are applied to compensate for endoscopic image quality deficiencies.

  11. Peroral endoscopic myotomy (POEM) leads to similar results in patients with and without prior endoscopic or surgical therapy. (United States)

    Orenstein, Sean B; Raigani, Siavash; Wu, Yuhsin V; Pauli, Eric M; Phillips, Melissa S; Ponsky, Jeffrey L; Marks, Jeffrey M


    Traditional treatment for the esophageal motility disorder, achalasia, ranges from endoscopic botulinum toxin (Botox) injections or balloon dilatation, to laparoscopic or open surgical myotomy. Recent advances in endoscopic therapy have led to peroral endoscopic myotomy (POEM) as a viable alternative to traditional techniques for myotomy. Uncertainty exists as to whether the procedure is feasible for patients who have already received prior endoscopic or surgical procedures for therapy, as these groups experience higher failure rates as well as intraoperative mucosal perforations and technical difficulty during Heller myotomy. We describe our first 40 patients who have undergone POEM and compare outcomes between patients who have or have not received previous treatment for achalasia. We evaluated our prospectively collected database of POEM procedures performed by two surgeons (JLP and JMM) at a single institution. Perioperative data was collected for operative and hospital outcomes. Patients completed pre- and postoperative GERD-Health-Related Quality of Life Questionnaires (GERD-HRQL) and SF-12 surveys for symptom scoring. Forty patients received a POEM procedure between 2011 and 2013. Of these, 40% (n = 16) had had at least one prior endoscopic or surgical procedure. Nine had prior Botox injections, 7 had balloon dilations, 3 had both Botox and dilations, and 3 received prior laparoscopic Heller myotomy (two with Dor fundoplication). Mean operative time was 102 min for patients with prior procedures (Prior Tx) and 118 min for patients without any prior procedure (No Tx) (p = 0.07). Intraoperative complication rates for the Prior Tx group were 12.5 versus 16.7% for the No Tx group. Mean follow-up was 10 months. Both groups independently demonstrated clinical improvement in both the GERD-HRQL and SF-12 scores following POEM. There were no statistical differences between the two groups for GERD-HRQL reflux and dysphagia subset scores, or SF-12 mental component

  12. Endoscopic sphincterotomy plus large-balloon dilation vs endoscopic sphincterotomy for choledocholithiasis: a meta-analysis. (United States)

    Yang, Xiao-Ming; Hu, Bing


    To perform a meta-analysis of large-balloon dilation (LBD) plus endoscopic sphincterotomy (EST) vs EST alone for removal of bile duct stones. Databases including PubMed, EMBASE, the Cochrane Library, the Science Citation Index, and important meeting abstracts were searched and evaluated by two reviewers independently. The main outcome measures included: complete stone removal, stone removal in the first session, use of mechanical lithotripsy, procedure time, and procedure-related complications. A fixed-effects model weighted by the Mantel-Haenszel method was used for pooling the odds ratio (OR) when heterogeneity was not significant among the studies. When a Q test or I² statistic indicated substantial heterogeneity, a random-effects model weighted by the DerSimonian-Laird method was used. Six randomized controlled trials involving 835 patients were analyzed. There was no significant heterogeneity for most results; we analyzed these using a fixed-effects model. Meta-analysis showed EST plus LBD caused fewer overall complications than EST alone (OR = 0.53, 95%CI: 0.33-0.85, P = 0.008); subcategory analysis indicated a significantly lower risk of perforation in the EST plus LBD group (Peto OR = 0.14, 95%CI: 0.20-0.98, P = 0.05). Use of mechanical lithotripsy in the EST plus LBD group decreased significantly (OR = 0.26, 95%CI: 0.08-0.82, P = 0.02), especially in patients with a stone size larger than 15 mm (OR = 0.15, 95%CI: 0.03-0.68, P = 0.01). There were no significant differences between the two groups regarding complete stone removal, stone removal in the first session, post-endoscopic retrograde cholangiopancreatography pancreatitis, bleeding, infection of biliary tract, and procedure time. EST plus LBD is an effective approach for the removal of large bile duct stones, causing fewer complications than EST alone.

  13. Multiple, Pan-Enteric Perforation Secondary to Intestinal Tuberculosis

    Irfan Masood


    Full Text Available Free perforation is one of the most feared complications of the intestinal tuberculosis. The terminal ileum is the most common site of perforation, while the majority of (90% perforations are solitary. Herein, we describe a case of a 25-year-old male who presented with generalized peritonitis requiring an emergency exploratory laparotomy, which revealed pan-enteric perforation characterized by multiple perforations of the small bowel extending 10–15 cm from the DJ flexure up to the terminal ileum. The perforations were primarily closed, while 6–8 cm of the diseased terminal ileum was resected and the two ends were brought out as double-barreled ostomy. To the best of our knowledge, such an extensive tuberculous perforation of the small bowel has not been previously reported in the literature before.

    Thirty-nine patients (forty-four joints) who had been diagnosed as having meniscus perforation of the temporomandibular joint by inferior joint space arthrography and had been treated by surgical procedures were evaluated retrospectively. Information of clinical findings, arthrotomographic findings and surgical findings was collected on a standardized form and evaluated. The results were as follows: 1. On the 34 patients of 38 joints which were surgically confirmed perforation of meniscus or its attachments of the temporomandibular joint, there were 29 females and 5 males (5.8:1). The average age was 36 years (range 17 to 70). 2. The common clinical findings of group that had meniscus displacement without reduction and with perforation were pain on the affected joint and limitation of mouth opening. In the group showing meniscus displacement with reduction and with perforation the common clinical findings were pain and clicking on the affected joint. 3. 32 joints (84.2%) were arthrotomographically anterior meniscus displacement without reduction and with perforation, 6 joints (15.8%) showed anterior meniscus displacement with reduction and with perforation. 4. Joints categorized arthrotomographically as having meniscus displacement without reduction and with perforation were less likely to have full translation of the condyle in comparison with the normal or meniscus displacement with reduction and with perforation groups (p<0.05) 5. The arthrographic findings of 44 joints having meniscus perforation were compared with surgical findings, there were 6 false positive findings of meniscus perforation, the reliability of arthrographic findings of meniscus perforation was a 86.4% correlation with surgical findings. 6. On the site of perforations of 38 joints which were surgically confirmed perforation of meniscus or its attachments, twenty-three of perforations (60.5%) were in location at the junction of the meniscus and posterior attachment, fourteen (36.9%) were

    Background and Aims. Endoscopic submucosal dissection (ESD) is not widely used in large colorectal lesions because of technical difficulty and possible complications. We aimed to examine the efficacy and safety of ESD for large colorectal neoplasms. Patients and Methods. During the past 5 years, 608 cases of colorectal neoplasm (≧20 mm) were treated by ESD. They were divided into Group A (20–49 mm, 511 cases) and Group B (≧50 mm, 97 cases). Results. The average age, lesion size, and procedure time were 67.4 years, 30.0 mm, and 60.0 min in Group A, and they were 67.1 years, 64.2 mm, and 119.6 min in Group B. En bloc resection rates were 99.2% and 99.0% (P = 0.80), and complication rates were 4.1% and 9.9% (P = 0.03). Complications in Group A consisted of perforation (2.7%), bleeding (1.2%), and ischemic colitis (0.2%). Those in Group B were perforation (8.2%) and bleeding (1.0%). Two cases in Group A and none in Group B required emergency surgery for perforation. Conclusions. There was no difference in efficacy between Groups A and B. Complications were more frequent in Group B, but all perforations in Group B were successfully managed conservatively. ESD can be effective and safe for large colorectal tumors. PMID:24072998

  16. Diagnosis of Acute Appendicitis by Endoscopic Retrograde Appendicitis Therapy (ERAT): Combination of Colonoscopy and Endoscopic Retrograde Appendicography. (United States)

    Li, Yingchao; Mi, Chen; Li, Weizhi; She, Junjun


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

    Berrizbeitia, Luis D; Calello, Diane P; Dhir, Nisha; O'Reilly, Colin; Marcus, Steven


    Ingestion of liquid nitrogen is rare but carries catastrophic complications related to barotrauma to the gastrointestinal tract. We describe a case of ingestion of liquid nitrogen followed by gastric perforation and respiratory insufficiency and discuss the mechanism of injury and management of this condition. Liquid nitrogen is widely available and is frequently used in classroom settings, in gastronomy, and for recreational purposes. Given the potentially lethal complications of ingestion, regulation of its use, acquisition, and storage may be appropriate.

The group included 16 men (88% and two women (11%; the mean age was 24 (15–33 years. In each case, vitrectomy was scheduled 1–6 weeks after repair of the entrance site. Associated retinal detachments were observed in two eyes (11%, retinal incarceration was observed surrounding the exit site in three eyes (16%, and retention of an intraocular foreign body was observed in two cases. After a follow-up period of 8 ± 2 months, two eyes (11% had achieved visual acuity (VA of 0.5, nine eyes (50% had achieved VA between 0.5 and 0.1, and seven eyes (38% had achieved VA between 0.1 and hand movement. The main reasons for functional failure (VA 0.1 to hand movement were macular dragging (due to fibrosis at the exit site near the macula in seven cases (38%, submacular hemorrhage in four cases (22%, and epimacular fibrosis in five cases (27%. All cases developed postoperative exotropia. One case (5% developed postoperative hemorrhage. No cases exhibited signs of postoperative redetachment.Conclusion: The outcome of pars plana vitrectomy in cases with double perforations is variable. Factors including the surgeon's skill level, the time to surgery, and the efficacy of the intraocular tamponade affect the postoperative outcome.Keywords: pars plana vitrectomy, gunshot injury, double perforation

    Directory of Open Access Journals (Sweden)

    Yad Ram Yadav


    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

  5. Perforated jejunal diverticula: a case report

    Directory of Open Access Journals (Sweden)

    Collins Christopher G


    Full Text Available Abstract Introduction Jejunal diverticula are rare and are usually asymptomatic. However, they may cause chronic non-specific symptoms or rarely lead to an acute presentation. Case presentation We report the case of an 82-year-old Caucasian woman presenting with a one-day history of generalized abdominal pain, with three episodes of vomiting. An abdominal X-ray displayed multiple dilated loops of the small bowel. A subsequent computed tomography scan of the abdomen and pelvis revealed a thickening of the duodenum and dilatation of the proximal jejunum. Multiple small bowel diverticula were identified with surrounding pockets of free air adjacent to the jejunal diverticula suggestive of a small bowel perforation. Our patient underwent a laparotomy, which identified multiple jejunal diverticula with two pinhole jejunal perforations and associated fecal contamination. The perforations were repaired with primary closure and extensive washout was performed. Conclusion Jejunal diverticulosis in the elderly can lead to significant morbidity and mortality and so should be suspected in those presenting with crampy abdominal pain and altered bowel habits.

    Zeltzer, Assaf A; De Baerdemaeker, Randy A; Hendrickx, Benoit; Seidenstücker, Katrin; Brussaard, Carola; Hamdi, Moustapha


    Abdominal scars are no longer a contra-indication for abdominal perforator flap harvesting. Few research data exists about the regeneration potential of the abdominal wall's perforator system. Therefore, previous abdominoplasty with umbilical transposition is an absolute contra-indication for a DIEaP-flap (deep inferior epigastric artery perforator flap). A 50-year-old patient required a breast reconstruction of the right breast, 10 years after an abdominoplasty with undermining of the superior abdomen and umbilical transposition. The patient was scheduled for a free lumbar artery perforator (LaP) flap. The preoperative computed tomography-angiography mapping showed nice lumbar perforators and to our surprise a good-sized DIEa perforator in the peri-umbilical region. The DIEa perforator on the right hemi-abdomen, consisting of two veins and one artery, was pulsatile and found suitable in size. A classical flap harvest and transfer was further performed. This case report is the first in which a dominant perforator is found in the area of undermining after a full abdominoplasty with umbilical repositioning. Further investigations regarding the nature and timing of re-permeation or regeneration of perforators after abdominoplasty are to be done. Nevertheless, we are convinced that with appropriate perforator mapping and a suitable plan B, previous abdominoplasty is no longer an absolute but a relative contra-indication for performing DIEaP-flap.

  7. Frequency Dependence Hearing Loss Evaluation in Perforated Tympanic Membrane. (United States)

    Dawood, Mohammed Radef


    Introduction  Tympanic membrane perforation is a relatively common problem that predisposes patients to varying degrees of conductive hearing loss. Objective  The objective of this study is to evaluate and analyze the frequency dependence hearing loss in tympanic membrane perforation based on the size and the site of perforation. Methods  For the study, I selected 71 patients' (89) ears for the cross-sectional study with tympanic membrane perforations; I examined the size and the site of perforations under the microscope and classified them into small, moderate, large, and subtotal perforations, and into anterior central, posterior central, malleolor central, and big central perforations. I measured mean level of speech frequencies hearing loss, and its relation with the site and the size of the perforation analyzed. Results  The mean hearing loss at different sizes of the perforation at all speech frequencies was 37.4 dB, with ABG of 26.6 dB, and its maximum loss was detected in subtotal perforation of 42.3 dB, with ABG of 33.7 dB, at 500 Hz frequency, while in relation to the sites, it was 38.2 dB, with ABG of 26.8 dB, and its maximum loss was detected in big central site perforation of 42.1 dB, with ABG of 33.6 dB, at 500 Hz frequency. Conclusions  The hearing loss was proportionally related with the sizes of the perforations, and the posterior site had greater impact on the hearing than anterior site perforations. This was also applied to the frequency dependence hearing level, as was detected to be worse at lower frequencies as 500 Hz, than those of 1000-2000 Hz.

  9. The Challenging Buried Bumper Syndrome after Percutaneous Endoscopic Gastrostomy

    Directory of Open Access Journals (Sweden)

    Ibrahim Afifi


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

  10. Endoscopic stapling of pharyngeal pouch: a 10-year review of single versus multiple staple rows. (United States)

    Roth, Jason A; Sigston, Elizabeth; Vallance, Neil


    To compare the outcomes obtained in patients undergoing endoscopic stapling of pharyngeal pouches with single versus multiple rows of staples. A retrospective, 10-year review. Review of medical records in 38 patients who underwent endoscopic pharyngeal pouch repair. Patients who underwent stapling with multiple rows had a higher postoperative leak rate than patients who were stapled with a single row (36% vs 0%, P multiple rows also had a more prolonged length of stay and a slower return to both clear fluids and solid diet (P row of staples may be necessary to divide the common wall. However, in our series this is associated with a significantly increased risk of esophageal or pouch perforation. Care should be taken during the placement of multiple rows of staples.

  11. The perforator angiosome: a new concept in the design of deep inferior epigastric artery perforator flaps for breast reconstruction. (United States)

    Rozen, Warren M; Ashton, Mark W; Le Roux, Cara Michelle; Pan, Wei-Ren; Corlett, Russell J


    The previously described "perfusion zones" of the abdominal wall vasculature are based on filling of the deep inferior epigastric artery (DIEA) and all its branches simultaneously. With the advent of the DIEA perforator flap, only a single or several perforators are included in supply to the flap. As such, a new model for abdominal wall perfusion has become necessary. The concept of a "perforator angiosome" is thus explored. A clinical and cadaveric study of 155 abdominal walls was undertaken. This comprised the use of 10 whole, unembalmed cadaveric abdominal walls for angiographic studies, and 145 abdominal wall computed tomographic angiograms (CTAs) in patients undergoing preoperative imaging of the abdominal wall vasculature. The evaluation of the subcutaneous branching pattern and zone of perfusion of individual DIEA perforators was explored, particularly exploring differences between medial and lateral row perforators. Fundamental differences exist between medial row and lateral row perforators, with medial row perforators larger (1.3 mm vs. 1 mm) and more likely to ramify in the subcutaneous fat toward the contralateral hemiabdomen (98% of cases vs. 2% of cases). A model for the perfusion of the abdominal wall based on a single perforator is presented. The "perforator angiosome" is dependent on perforator location, and can mapped individually with the use of preoperative imaging.

    Full Text Available Tsunamis have damaged bridges to various extents in the 2004 Indian Ocean Tsunami. This paper reports an experimental investigation of the effect of perforations in the girders and parapets on the horizontal tsunami loads. The results reveal that the maximum pressures impinging on the front face of the pier and deck are 4.5 and 3 times the hydrostatic pressure at 80mm nominal wave heights. The percentage of force reduction of the bridge deck with 10% perforated girders and 60% perforated parapets is found to be close to the percentage of perforation area in the deck. However, it is also noted that perforations in the bridge deck can substantially reduce the tsunami forces acting on it throughout the force time history. Thus, less damage to the bridge is anticipated for the bridge deck with perforations in girders and parapets.

  13. Perforation rate of intraoral barriers for direct digital radiography. (United States)

    Choi, J-W


    This study aimed to assess the perforation rate of intraoral barriers for a direct digital sensor according to the barrier application. Four types of plastic barriers with different thicknesses and one type of latex finger cot were applied using six modified techniques. The perforations in barrier samples of six groups were examined by a water pressure test. The differences in the perforation rates among the six barrier applications were calculated. The least perforation occurred in Group 4 (0.08-mm-thick single barrier, 22%) and the most in Group 1 (0.04-mm-thick single barrier, 58%). An ANOVA test revealed statistical differences in the perforation rate among the groups (p = 0.00; 95% confidence interval, 0.326-0.403). The use of double barriers can be helpful in reducing the perforation rate of intraoral barriers.

  14. MR Enterography of Inflammatory Bowel Disease with Endoscopic Correlation. (United States)

    Kaushal, Pankaj; Somwaru, Alexander S; Charabaty, Aline; Levy, Angela D


    Crohn disease (CD) and ulcerative colitis (UC) are the two main forms of idiopathic inflammatory bowel disease (IBD). CD is a transmural chronic inflammatory disorder that can affect any part of the gastrointestinal tract in a discontinuous distribution. UC is a mucosal and submucosal chronic inflammatory disease that typically originates in the rectum and may extend proximally in a continuous manner. In treating patients with CD and UC, clinicians rely heavily on accurate diagnoses and disease staging. Magnetic resonance (MR) enterography used in conjunction with endoscopy and histopathologic analysis can help accurately diagnose and manage disease in the majority of patients. Endoscopy is more sensitive for detection of the early-manifesting mucosal abnormalities seen with IBD and enables histopathologic sampling. MR enterography yields more insightful information about the pathologic changes seen deep to the mucosal layer of the gastrointestinal tract wall and to those portions of the small bowel that are not accessible endoscopically. CD can be classified into active inflammatory, fistulizing and perforating, fibrostenotic, and reparative and regenerative phases of disease. Although CD has a progressive course, there is no stepwise progression between these disease phases, and various phases may exist at the same time. The endoscopic and MR enterographic features of UC can be broadly divided into two categories: acute phase and subacute-chronic phase. Understanding the endoscopic features of IBD and the pathologic processes that cause the MR enterographic findings of IBD can help improve the accuracy of disease characterization and thus optimize the medication and surgical therapies for these patients.

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

    Directory of Open Access Journals (Sweden)

    Ricardo Landini Lutaif Dolci

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

    Tseng, Chih-Chieh; Lai, Ming-Tang; Wu, Chia-Che; Yuan, Sheng-Po; Ding, Yi-Fang


    Microscopic tympanoplasty has been the standard surgery for repairing perforated tympanic membranes since the 1950s, but endoscopic tympanoplasty has been increasingly practiced since the late 1990s. In this study, we compared the efficacies of endoscopic and microscopic tympanoplasty. PubMed, Embase, MEDLINE, and the Clinical Trial Register. We conducted a systematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement. We included clinical studies that compared the efficacies of endoscopic and microscopic tympanoplasty. We assessed the risk of bias and calculated the pooled relative risk (RR) estimates with 95% confidence interval (CI). We identified four studies (involving 266 patients in total) that met the inclusion criteria. The pooled tympanic membrane closure rates and hearing results of endoscopic and microscopic tympanoplasty were comparable (85.1% vs. 86.4%, respectively; RR: 0.98; 95% CI: 0.85 to 1.11; I(2) = 0) (mean difference of improvements of air-bone gaps: -2.73; 95% CI: -6.73 to 1.28; I(2) = 80%). The pooled canalplasty rate of endoscopic tympanoplasty was significantly lower than that of microscopic tympanoplasty. Patients receiving endoscopic tympanoplasty had a more desirable cosmetic result than did those receiving microscopic tympanoplasty. Our up-to-date review evidences the comparable tympanic membrane closure rates and hearing results for endoscopic and microscopic tympanoplasty. Patients receiving endoscopic tympanoplasty have a lower canalplasty rate and more desirable cosmetic result than do those receiving microscopic tympanoplasty.

    Duodenal diverticulum is common, but its perforation is a rare complication. Duodenal diverticulum perforation requires prompt treatments because of its high mortality rate. However, an accurate diagnosis is difficult to make due to nonspecific symptoms and signs. It can be misdiagnosed as pancreatitis, cholecystitis, or peptic ulcer. Herein, we report a case of perforated duodenal diverticulum caused by bezoar in a 33-year-old woman whom was diagnosed by abdomen computed tomography and ultrasonography.

    Full Text Available BACKGROUND Though single sitting myringoplasty using temporalis fascia under general anaesthesia has been documented in many studies, but ours is the first center to have started using tragal cartilage and temporalis fascia harvested from one ear to do bilateral myringoplasty in one sitting using local anaesthesia with excellent results including very good graft uptake rate and audiological improvement without significant complications. The aim of the study is to compare the outcome of bilateral myringoplasty in dry central perforation in one sitting using cartilage on one side and temporalis fascia on the other ear in an urban tertiary care centre. MATERIALS AND METHODS A total of 50 patients above the age of 15 years were included in the study who had dried bilateral perforated ear drum involving pars tensa both sides size of perforation and hearing loss were more or less-matched patients who had persistently discharging ear or had evidence of middle ear infection, granulation tissues, aural polypi, cholesteatoma, ossicular erosion or evidence of sensorineural hearing loss were excluded from the study. In the cases, temporalis fascia graft through postaural incision right side and conchal cartilage was harvested from the right side and endoscopic myringoplasty was performed. Temporalis fascia graft placed by underlay technique and conchal cartilage was used as graft on the left side for all the patients. Patients were followed up after 3 and 6 months to assess closure of tympanic membrane perforation and hearing improvement as depicted by closure of air above gap on pure tone audiometry at 6 months. Study Design- Interventional, descriptive. Place and Duration of Study- Department of ENT, UIORL, Madras Medical College and Rajiv Gandhi Government General Hospital, June 2012 to July 2013. RESULTS A total of 100 myringoplasties were performed on 50 patients included in the study. Majority of the patients included were having medium to large size

    Here, we report the first successful endoscopic resection of an exophytic gastrointestinal stromal tumor (GIST) using a novel perforation-free suction excavation technique. A 49-year-old woman presented for further management of a gastric subepithelial tumor on the lesser curvature of the lower body, originally detected via routine upper gastrointestinal endoscopy. Abdominal computed tomography and endoscopic ultrasound showed a 4-cm extraluminally protruding mass originating from the muscularis propria layer. The patient firmly refused surgical resection owing to potential cardiac problems, and informed consent was obtained for endoscopic removal. Careful dissection and suction of the tumor was repeated until successful extraction was achieved without serosal injury. We named this procedure the suction excavation technique. The tumor's dimensions were 3.5 cm × 2.8 cm × 2.5 cm. The tumor was positive for C-KIT and CD34 by immunohistochemical staining. The mitotic count was 6/50 high-power fields. The patient was followed for 5 years without tumor recurrence. This case demonstrated the use of endoscopic resection of an exophytic GIST using the suction excavation technique as a potential therapy without surgical resection.

    Ye, Li-ping; Zhu, Lin-hong; Zhou, Xian-bin; Mao, Xin-li; Zhang, Yu


    This study was designed to evaluate the safety and efficacy of endoscopic excavation for esophageal subepithelial tumors originating from the muscularis propria. Forty-five patients with esophageal subepithelial tumors originating from the muscularis propria were treated with endoscopic excavation between January 2010 and June 2012. The key steps were: (1) making several dots around the tumor; (2) incising the mucosa along with the marker dots, and then seperating the tumor from the muscularis propria by using a hook knife or an insulated-tip knife; (3) closing the artificial ulcer with clips after the tumor was removed. The mean tumor diameter was 1.1 ± 0.6 cm. Endoscopic excavation was successfully performed in 43 out of 45 cases (95.6%), the other 2 cases were ligated with nylon rope. During the procedure perforation occurred in 4 (8.9%) patients, who recovered after conservative treatment. No massive bleeding or delayed bleeding occurred. Histologic diagnosis was obtained from 43 (95.6%) patients. Pathological diagnoses of these tumors were leiomyomas (38/43) and gastrointestinal stromal tumors (5/43). Endoscopic excavation is a safe and effective method for the treatment of small esophageal subepithelial tumors originating from the muscularis propria.

    To evaluate the efficacy and safety of the endoscopic management of Zenker Diverticulum with IT-Knife 2 device. prospective and multicenter study (Edgardo Rebagliati Martins National Hospital and Golf Clinic). We included all patients with sintomatic Zenker Diverticulum that were treated with endoscopic cricopharyngeal miotomy from september 2013 until august 2016. the diverticulum septum was faced with a cap, and then it was cut by the IT-Knife 2 (ENDOCUT Q, effect 3-2-5) until its baseline. Disphagia score was compared before and 1 and 3 months after the procedure. 20 patients were included (11 men; average age: 71 years). The median size of Zenker Diverticulum was 40.5 mm. The median duration of the cricopharyngeal miotomy was 13.75 minutes. Clinical success was 100%. There was a significative decrease (pdisphagia score from 2+/-0.86 before the procedure to 0.05+/-0.22 one month after it. Recurrence after 3 months was 15% and it was completely solved after a second endoscopic treatment. Niether perforation nor bleeding was reported. Two patients had pneumonia. the endoscopic management of Zenker Diverticulum with IT-Knife 2 is highly effective, safe and less complex than previous technique experience.

    We experienced ileal perforation caused by dislocated biliary endoprosthesis in 59 years old female patient. The endoprosthesis was implanted due to biliary fistula after laparoscopic cholecystectomy 2 years before the perforation. It seems that endoprosthesis dislocation and the perforation were the result of too long stay of endoprosthesis. After the surgical management and the removal of the prosthesis patient was cured. Although ileal perforation caused by dislocated biliary endoprosthesis is rare, clinicians should be aware of the possibility of its occurrence. © 2015 MEDPRESS.

    Full Text Available Dengue viral infections have become one of major emerging infectious diseases in the tropics. Acute abdomen occurring in dengue viral infection is not uncommon. The spectrums of acute surgical emergencies which raise suspicion of an abdominal catastrophe in patients presenting with dengue fever include acute pancreatitis, acute acalculous cholecystitis, non-specific peritonitis and very rarely acute appendicitis. The presence of low white cell count and platelet count can raise suspicion of a diagnosis of dengue in a patient presenting with acute abdominal pain, during a dengue epidemic. We herein report three patients with dengue fever who had appendicular perforation during the course of their viral fever.

  8. Endoscopic Transaxillary Near Total Thyroidectomy (United States)

    Ejeh, Ijeoma Acholonu; Speights, Fredne; Rashid, Qammar N.; Ideis, Mustafa


    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 Background: The early diagnosis of acute appendicitis before progression to gangrene or abscess formation is recognized as important to minimize morbidity from this common disease process. The aim of this study was to assess the value of different risk factors in the diagnosis of perforation. Methods: This descriptive-analytic and retrospective study was conducted to investigate epidemiological characteristics in patients with perforated and non-perforated appendicitis. A series of 1311 patients who were operated on for acute appendicitis between years 1380-1382 in Shahid Beheshti and Yahya-nejad hospitals were reviewed.. Data gathered included age at operation, gender, care sought prior to admission for appendectomy including antibiotic and analgesic therapy, time of presentation in the year, duration of symptoms, signs and symptoms at the time of admission, and the patient’s living area. Results: One hundred twenty one of 1311 patients (9% had perforated appendicitis and 1190 patients (91% had unperforated appendicitis. Presentation and referral in the first 6-month was associated with higher perforation rate. Patients from rural area showed a higher rate of perforations. The perforation rate was significantly higher in elderly patients (>65 year. When the duration of symptoms was more than 12 hours at presentation, the risk of perforation showed a five-fold increase. 30.7% of perforated cases had used antibiotic or sedative before referring to the hospital. Conclusion: Appendiceal perforation continues to be a complication in patients with acute appendicitis and increased in the frequency as the age of the patients increase and the duration of symptoms lengthen. We also found that the perforation rate is higher in patients from rural area and in whom present in the first 6-month of the year, a finding that was not reported so far.

    To evaluate the usefulness of CT for assessing the location and cause of pathologic gastrointestinal perforation. A retrospective analysis of abdominal CT was performed in 27 perforations of 26 patients with underlying gastrointestinal pathology. Fifteen benign and 12 malignant perforations consisted of five gastric cancers, one gastric ulcer, ten duodenal bulb ulcers. two bowel adhesions, one jejunal metastasis from lung cancer, one ileocolic Crohn's disease, one radiation colitis and six colon cancers. CT scans were evaluated for (1) diagnosis of bowel perforation, (2) assessment of the cause and site of perforation, and, in particular, differentiation between benignancy and malignancy, and (3) complications and their extent. CT easily detected varying amounts of free air or fluid collection, and infiltration or abscess formation adjacent to the main lesion, and the diagnosis of gastrointestinal perforation was therefore easy. In 11 of the 12 malignancies (92%), primary tumor was diagnosed, but detection of the site of perforation was possible in only seven cases(7/12, 58%). The 15 benign lesions revealed nonspecific CT findings, and the perforation site could be presumed in six (6/15, 40%). In one case of Crohn's disease, the primary cause was visualized. Among six colonic cancers, four pericolic abscesses and two fistulas to adjacent organs were found, but there was no evidence of diffuse peritonitis. CT was helpful to lead to optimal treatment of pathologic gastrointestinal On CT the detectability of perforation, primary benign or malignant lesion, perforation site and extent of complication was high, and this modality was therefore a useful indicator of the optimal treatment for pathologic gastrointestinal perforations.=20.

  11. Efficacy of Endoscopic Fluorescein Video Angiography in Aneurysm Surgery-Novel and Innovative Assessment of Vascular Blood Flow in the Dead Angles of the Microscope. (United States)

    Hashimoto, Koji; Kinouchi, Hiroyuki; Yoshioka, Hideyuki; Kanemaru, Kazuya; Ogiwara, Masakazu; Yagi, Takashi; Wakai, Takuma; Fukumoto, Yuichiro


    In aneurysm surgery, assessment of the blood flow around the aneurysm is crucial. Recently, intraoperative fluorescence video angiography has been widely adopted for this purpose. However, the observation field of this procedure is limited to the microscopic view, and it is difficult to visualize blood flow obscured by the skull base anatomy, parent arteries, and aneurysm. To demonstrate the efficacy of a new small-caliber endoscopic fluorescence video angiography system employing sodium fluorescein in aneurysm surgery for the first time. Eighteen patients with 18 cerebral aneurysms were enrolled in this study. Both microscopic fluorescence angiography and endoscopic fluorescein video angiography were performed before and after clip placement. Endoscopic fluorescein video angiography provided bright fluorescence imaging even with a 2.7-mm-diameter endoscope and clearly revealed blood flow within the vessels in the dead angle areas of the microscope in all 18 aneurysms. Consequently, it revealed information about aneurysmal occlusion and perforator patency in 15 aneurysms (83.3%) that was not obtainable with microscopic fluorescence video angiography. Furthermore, only endoscopic video angiography detected the incomplete clipping in 2 aneurysms and the occlusion of the perforating branches in 3 aneurysms, which led to the reapplication of clips in 2 aneurysms. The innovative endoscopic fluorescein video angiography system we developed features a small-caliber endoscope and bright fluorescence images. Because it reveals blood flow in the dead angle areas of the microscope, this novel system could contribute to the safety and long-term effectiveness of aneurysm surgery even in a narrow operative field.

  13. Flexible endoscopic treatment for Zenker's diverticulum with the SB Knife. Preliminary results from a single-center experience. (United States)

    Battaglia, Giorgio; Antonello, Alessandro; Realdon, Stefano; Cesarotto, Martina; Zanatta, Lisa; Ishaq, Sauid


    Flexible endoscopic septum division is becoming a prominent treatment option for Zenker's diverticulum (ZD). Over the years, various techniques have been developed and many cutting tools have been tested with varying results. We report our experience with a recently designed, monopolar, rotating, scissor-shaped device (SB Knife). Data on 31 consecutive patients that underwent flexible endoscopic treatment for ZD with the use of the SB Knife were retrieved. Dysphagia, regurgitation, and respiratory symptom severity before the procedure were graded. Procedure duration, rate of complications, symptom changes after the procedure and rate of relapsing patients during follow up were recorded. The procedure was carried out successfully in all patients. Median procedure time was 14 min. One case of late-onset bleeding developed 1 week after the procedure, and was managed endoscopically. A significant symptom improvement was achieved (dysphagia: median score 0, P 0, P 0, P = 0.009). Two patients had mild relapsing symptoms, respectively, after 4 and 9 months from the procedure but refused further treatment. Endoscopic treatment of ZD using this new device is safe and efficient at short term follow up. No perforations were observed and there was a substantial reduction of symptoms after the treatment. Larger studies are needed to fully assess advantages of this new device for endoscopic treatment of ZD. © 2015 The Authors. Digestive Endoscopy © 2015 Japan Gastroenterological Endoscopy Society.

  14. To Pull or to Scope: A Prospective Safety and Cost-effectiveness of Percutaneous Endoscopic Gastrostomy Tube Replacement Methods. (United States)

    Khoury, Tawfik; Daher, Saleh; Yaari, Shaul; Rmeileh, Ayman Abu; Israeli, Eran; Benson, Ariel A; Cohen, Jonah; Arnon, Ron; Mizrahi, Meir


    Percutaneous endoscopic gastrostomy (PEG) tubes are routinely used as an effective method for providing enteral nutrition. The need for their exchange is common. We aimed to examine the comparative safety and cost-effectiveness of PEG percutaneous counter-traction "pulling" approach or by endoscopically guided retrieval. A prospective 215 consecutive patients undergoing PEG tube insertion were included. Fifty patients in total were excluded. The patients were examined for demographics, indications for PEG replacement, as well as procedure-related complications and procedural costs. Group A included 70 patients (42%) with PEG tubes replaced endoscopically, whereas group B included 95 patients (58%) with PEG tubes replaced percutaneously. Baselines characteristics were similar between the 2 groups (P=NS). Group A and group B had similar immediate complication rates including 4 patients in group B (4.2%), and 2 patients in group A (2.8%) (P=0.24). Complications included a conservatively managed esophageal perforation, and self-limited mild bleeding groups A and group B, respectively. The mean procedure cost was significantly higher in the endoscopic PEG replacement group compared with the percutaneous PEG replacement group ($650 vs. $350, respectively). Percutaneous PEG replacement appears as safe as endoscopic PEG replacement, however, percutaneous tube exchange is less costly.

  15. [Drug related colonic perforation: Case report]. (United States)

    Núñez-García, Edgar; Valencia-García, Luis César; Sordo-Mejía, Ricardo; Kajomovitz-Bialostozky, Daniel; Chousleb-Kalach, Alberto


    Acute pseudo-obstruction of the colon is a disorder characterised by an increase in intra-luminal pressure that leads to ischaemia and necrosis of the intestinal wall. The mechanism that produces the lesion is unknown, although it has been associated with: trauma, anaesthesia, or drugs that alter the autonomic nervous system. The pathophysiology of medication induced colon toxicity can progress to a perforated colon and potentially death. Present a case of a colonic pseudo-obstruction in a patient with polypharmacy as the only risk factor and to review the medical literature related to the treatment of this pathology. The case is presented of a 67 year old woman with colonic pseudo-obstruction who presented with diffuse abdominal pain and distension. The pain progressed and reached an intensity of 8/10, and was accompanied by fever and tachycardia. There was evidence of free intraperitoneal air in the radiological studies. The only risk factor was the use of multiple drugs. The colonic pseudo-obstruction progressed to intestinal perforation, requiring surgical treatment, which resolved the problem successfully. It is important to consider drug interaction in patients with multiple diseases, as it may develop complications that can be avoided if detected on time.

    López-Zamudio, José; Ramírez-González, Luis Ricardo; Núñez-Márquez, Julia; Fuentes Orozco, Clotilde; González Ojeda, Alejandro; Leonher-Ruezga, Karla Lisseth


    Gastric non-Hodgkin lymphoma is a rare tumour that represents approximately 7% of all stomach cancers and 2% of all lymphomas. The most frequent location of gastric MALT (mucosa associated lymphoid tissue) lymphomas is in the antrum in 41% of the cases, and 33% can be multifocal. The risk of spontaneous perforation of a gastric MALT lymphoma is 4-10%. 24 year old male patient carrying the Human Immunodeficiency Virus, who began with signs and symptoms of acute abdomen and fever 72 hours before arriving in the emergency room. A computed tomography was performed that showed free fluid in the cavity, and gastric wall thickening. The patient underwent a laparotomy, finding absence of the anterior wall of the stomach, sealed with the left lobe of the liver, colon and omentum. Total gastrectomy, with oesophagosty and jejunostomy tube, was performed. Gastric perforation secondary to a MALT lymphoma is rare, with high mortality. There is limited information reported of this complication and should be highly suspected in order to provide appropriate treatment for a complication of this type.

  17. Total extraperitoneal endoscopic hernioplasty (TEP). (United States)

    Kuthe, A; Mainik, F; Flade-Kuthe, R


    One can no longer think about modern hernia surgery without mentioning endoscopic techniques. But due to their high technical demands the learning curve is comparatively long. And by technical mistakes and their consequences (pain, recurrence, complications) the benefits of the endoscopic techniques can easily be turned to drawbacks. The following text explains the steps of the total extraperitoneal endoscopic hernioplasty (TEP) technique in detail pointing out alternatives and risks. From preparation, indication and positioning, from trocar placement to extraperitoneal dissection and mesh placement, the principles of TEP are elucidated in respect of local anatomy and possible complications. The text as well as the accompanying video in the Mediathek are based on the authors' 20 years of experience in the TEP technique. Both of them may help in safe TEP application to minimise the complication rate as well as recurrences. Then patients can benefit from the advantages of this technique.

  18. Endoscopic treatment of lumbar arachnoiditis. (United States)

    Warnke, J P; Mourgela, S


    The diagnosis of lumbar arachnoiditis remains complex and often inconclusive. Using the technique of lumbar subarachnoidal endoscopy (thecaloscopy), the pathology can be identified and the patient treated with long-term effects on the symptoms. Endoscopic operations were performed on 23 patients suffering from varying symptoms with an enlarged lumbar subarachnoidal space. Having confirmed the diagnosis of lumbar arachnoiditis, a number of endoscopic operations ranging from adhesiolysis to subarachno-epidurostomy were carried out. Radicular symptoms in lumbar arachnoiditis were successfully relieved by various endoscopic dissection techniques, such as restoration of the improved CSF flow by subarachno-epidurostomy along the rootlet. This has been identified as one of the causal factors of the clinical symptoms. In cases where lumbar pain persists in spite of a previous thecaloscopy, further treatment with a lumboperitoneal shunt device has proved most successful.

  19. Endoscopic Palliation for Pancreatic Cancer

    Directory of Open Access Journals (Sweden)

    Mihir Bakhru


    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.

  20. Colorectal endoscopic mucosal resection (EMR). (United States)

    Kandel, Pujan; Wallace, Michael B


    Colonoscopy has the benefit of detecting and treating precancerous adenomatous polyps and thus reduces mortality associated with CRC. Screening colonoscopy is the keystone for prevention of colorectal cancer. Over the last 20 years there has been increased in the management of large colorectal polyps from surgery to endoscopic removal techniques which is less invasive. Traditionally surgical resection was the treatment of choice for many years for larger polyps but colectomy poses significant morbidity of 14-46% and mortality of up to 7%. There are several advantages of endoscopic resection technique over surgery; it is less invasive, less expensive, has rapid recovery, and preserves the normal gut functions. In addition patient satisfaction and efficacy of EMR is higher with minor complications. Thus, this has facilitated the development of advanced resection technique for the treatment of large colorectal polyps called as endoscopic mucosal resection (EMR). Copyright © 2017 Elsevier Ltd.

  1. Motion magnification for endoscopic surgery (United States)

    McLeod, A. Jonathan; Baxter, John S. H.; de Ribaupierre, Sandrine; Peters, Terry M.


    Endoscopic and laparoscopic surgeries are used for many minimally invasive procedures but limit the visual and haptic feedback available to the surgeon. This can make vessel sparing procedures particularly challenging to perform. Previous approaches have focused on hardware intensive intraoperative imaging or augmented reality systems that are difficult to integrate into the operating room. This paper presents a simple approach in which motion is visually enhanced in the endoscopic video to reveal pulsating arteries. This is accomplished by amplifying subtle, periodic changes in intensity coinciding with the patient's pulse. This method is then applied to two procedures to illustrate its potential. The first, endoscopic third ventriculostomy, is a neurosurgical procedure where the floor of the third ventricle must be fenestrated without injury to the basilar artery. The second, nerve-sparing robotic prostatectomy, involves removing the prostate while limiting damage to the neurovascular bundles. In both procedures, motion magnification can enhance subtle pulsation in these structures to aid in identifying and avoiding them.

  9. The Heidelberg Appendicitis Score Predicts Perforated Appendicitis in Children. (United States)

    Boettcher, Michael; Günther, Patrick; Breil, Thomas


    In the future, surgical management of pediatric appendicitis might become limited to nonperforating appendicitis. Thus, it becomes increasingly important to differentiate advanced from simple appendicitis and to predict perforated appendicitis among a group of children with right-sided abdominal pain, which was the aim of this study. An institutionally approved, single-center retrospective analysis of all patients with appendectomy from January 2009 to December 2010 was conducted. All diagnostic aspects were evaluated to identify predictors and differentiators of perforated appendicitis. In 2 years, 157 children suffered from appendicitis. Perforation occurred in 47 (29.9%) of the patients. C-reactive protein (CRP) levels higher than 20 mg/dL ( P = .037) and free abdominal fluid on ultrasonography ( P = .031) are the most important features to differentiate perforated from simple appendicitis. Moreover, all children with perforation had a positive Heidelberg Appendicitis Score (HAS). A negative HAS excludes perforation in all cases (negative predictive value = 100%). Perforated appendicitis can be ruled out by the HAS. In a cohort with right-sided abdominal pain, perforation should be considered in children with high CRP levels and free fluids or abscess formation on ultrasound.

    Innumerable approaches to the ptotic brow and forehead have been described in the past. Over the last twenty-five years, we have used all these techniques in cosmetic and reconstructive patients. We have used the endoscopic brow lift technique since 1995. While no one technique is applicable to all patients, the endoscopic brow lift, with appropriate modifications for individual patients, can be used effectively for most patients with brow ptosis. We present the nuances of this technique and show several different fixation methods we have found useful.

  10. Perforated layer structures in liquid crystalline block copolymers (United States)

    Tenneti, Kishore; Chen, Xiaofang; Li, Christopher; Tu, Yingfeng; Wan, Xinhua; Zhou, Qi-Feng; Sics, Igors; Hsiao, Benjamin


    Phase structures of a series of poly(styrene-block-(2,5-bis-(4- methoxyphenyl)oxycarbonyl)styrene) (PS-b-PMPCS) liquid crystalline “rod-coil” block copolymers (LCBCPs) were investigated using thermal analysis, X-ray analysis and transmission electron microscopy. In the low molecular weight asymmetric BCP system, perforated layer structures were observed where the excessive PS molecules punctured the PMPCS domains and these perforations uniquely possess tetragonal in- plane symmetry. In the high molecular weight system, these perforated layer structures were observed in symmetric samples. Randomly initiated perforations became more regular and uniform upon blending with PS homopolymer in symmetric BCPs. These regular perforations also possess tetragonal in-plane symmetry.

  11. Spontaneous Uterine Perforation due to Pyometra Presenting as Acute Abdomen

    Directory of Open Access Journals (Sweden)

    Loabat Geranpayeh


    Full Text Available Spontaneous perforation of the uterus is rare, its incidence being about 0.01%–0.05%. We report a rare case of diffuse peritonitis caused by spontaneously perforated pyometra. A 63-year-old woman with severe abdominal pain was admitted to our hospital. Laparotomy was performed because of the suspicion of gastrointestinal perforation with generalized peritonitis. At laparotomy, about 900 mL of pus was found in the peritoneal cavity. There were no abnormal findings in the alimentary tract, liver, or gallbladder. A total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed. Pathological investigation of the surgical specimen revealed endometritis and myometritis of the uterus; but there was no evidence of malignancy, and the cervical canal was patent. Although spontaneously perforated pyometra is rare, a perforated pyometra should therefore also be considered when elderly women present with acute abdominal pain.

  12. The Role of Hemoclips Reinforcement in the Ligation-Assisted Endoscopic Enucleation for Small GISTs in Gastric Fundus

    Directory of Open Access Journals (Sweden)

    Ge Nan


    Full Text Available Background. Endoscopic ultrasonography- (EUS- assisted band ligation has been proven to be a safe and effective procedure for the treatment of small gastrointestinal stromal tumors (GISTs apart from the relatively high risk of the postligation perforation of the gastric fundus. The aim of this study is to investigate the efficacy of hemoclip reinforcement in treating small GISTs in the gastric fundus. Method. During a standard endoscopy, a transparent cap attached to the endoscopic tip was placed over the lesion to exert sustained maximal aspiration before a rubber band was released. Once a definite ligation was confirmed by EUS, the tumor was enucleated. Four to 6 hemoclips were placed on the folds around the ligation band to reduce the tension of the ligation site. Results. The small GISTs were resected completely in 192 patients. Two cases of delayed perforation were found 72 hours after the procedure and successfully treated with an ordinary conservative method. Conclusion. Hemoclip-reinforced endoscopic band ligation with systematic follow-up using EUS appears to be a simple and effective technique for the resection of small GISTs in the gastric fundus.

  15. Endoscopic treatment of orbital tumors. (United States)

    Signorelli, Francesco; Anile, Carmelo; Rigante, Mario; Paludetti, Gaetano; Pompucci, Angelo; Mangiola, Annunziato


    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.

    Magnetic anchor-guided endoscopic submucosal dissection (MAG-ESD) was developed to reduce adverse events such as bleeding and perforation and to facilitate ESD. However, the external electromagnet required miniaturization to make it suitable for daily clinical practice. To evaluate the feasibility of simplified MAG-ESD using permanent magnets. Case series. Nagoya University Hospital. Beagle dogs. The simplified MAG-ESD was performed on 10 representative areas of the stomachs of beagle dogs. The magnetic anchor consisted of an internal magnet attached to a hemoclip. The external and internal magnets were made from the rare earth neodymium. The feasibility of countertraction with good visualization using simplified MAG-ESD. The rate of perforation, the time required for preparation, and attaching the magnetic anchor were also evaluated. All lesions were successfully resected without perforation. The magnetic anchor could be controlled easily, and direct visualization was maintained by adequate counter traction. Preparing the magnetic anchor and grasping the mucosal edge using the hemoclip was easy and required a median of only 4 minutes (range, 2-7 minutes). Animal experiment, low number and lesion size. This simplified MAG-ESD is feasible and allowed excellent visualization in the dog stomach. The feasibility of this system should be assessed in humans.

    Henrik Thorlacius


    Full Text Available Objectives. Endoscopic submucosal dissection (ESD is an effective method for en bloc removal of large colorectal tumors in Japan, but this technique is not yet widely established in western countries. The purpose here was to report the experience of implementing colorectal ESD in Sweden. Methods. Twenty-nine patients with primarily nonmalignant and early colorectal neoplasms considered to be too difficult to remove en bloc with EMR underwent ESD. Five cases of invasive cancer underwent ESD due to high comorbidity excluding surgical intervention or as an unexpected finding. Results. The median age of the patients was 74 years. The median tumor size was 26 mm (range 11–89 mm. The median procedure time was 142 min (range 57–291 min. En bloc resection rate was 72% and the R0 resection rate was 69%. Two perforations occurred amounting to a perforation rate of 6.9%. Both patients with perforation could be managed conservatively. One bleeding occurred during ESD but no postoperative bleeding was observed. Conclusion. Our data confirms that ESD is an effective method for en bloc resection of large colorectal adenomas and early cancers. This study demonstrates that implementation of colorectal ESD is feasible in Sweden after proper training, careful patient selection, and standardization of the ESD procedure.

  1. Detection of Perforators Using Smartphone Thermal Imaging. (United States)

    Hardwicke, Joseph T; Osmani, Omer; Skillman, Joanna M


    Thermal imaging detects infrared radiation from an object, producing a thermogram that can be interpreted as a surrogate marker for cutaneous blood flow. To date, high-resolution cameras typically cost tens of thousands of dollars. The FLIR ONE is a smartphone-compatible miniature thermal imaging camera that currently retails at under $200. In a proof-of-concept study, patients and healthy volunteers were assessed with thermal imaging for (1) detecting and mapping perforators, (2) defining perforasomes, and (3) monitoring free flaps. Preoperative, intraoperative, and postoperative thermograms can assist in the planning, execution, and monitoring of free flaps, and the FLIR ONE provides a low-cost adjunct that could be applied to other areas of burns and plastic surgery.

    Yanagisawa, Asako; Hayama, Noriko; Amano, Hiroyuki; Nakamura, Makoto; Hirano, Satoshi; Nakamura, Sukeyuki; Tabeta, Hiroshi


    An 86-year-old Japanese man was diagnosed with stage IV lung adenocarcinoma. The patient was treated with crizotinib after echinoderm microtubule-associated protein-like 4 (EML4)-anaplastic lymphoma kinase (ALK) rearrangement was detected from his pleural effusion. He subsequently developed abdominal pain and rebound tenderness in the right lower abdomen. Contrast-enhanced abdominal CT showed a low-density area in the abdominal cavity. The size of the abscess was decreased by drainage and the administration of antibiotics. Fistulography revealed a fistula from the rectum to the abscess, and a diagnosis of lower intestinal tract perforation with abscess formation was made. Crizotinib was discontinued and treatment with alectinib was initiated. The patient remains under treatment as an outpatient at our department without adverse effects.

    Full Text Available Introduction. Bochdalek hernia is a congenital defect of the diaphragm that is usually diagnosed in the neonatal period and incidentally in asymptomatic adults. Small bowel incarceration in a right-sided Bochdalek hernia is exceptional for an adult. Case Presentation. A 54-year-old woman was admitted for acute dyspnea, tachycardia, hypotension, and fever. Five days before, she had been experiencing an episode of diffuse abdominal pain. The admission chest X-ray was interpreted as right pleural effusion and pneumothorax with left mediastinal shift. Chest tube drainage was purulent. The thoracoabdominal CT examination suspected an intestinal incarceration through a right diaphragmatic defect. At laparotomy, a right-sided Bochdalek hernia was confirmed with a complete necrosis of the incarcerated caecum. Ileocaecal resection was performed, but the patient died from delayed septic complications. Conclusion. Intrathoracic perforation of the caecum is a rare occurrence; delayed diagnosis due to misleading initial symptoms may lead to severe complications and poor prognosis.

  4. Spontaneous Perforation of Pyometra: A Case Report

    Directory of Open Access Journals (Sweden)


    Full Text Available Pyometra is the accumulation of purulent material in the uterine cavity. Its reported incidence is 0.01–0.5% in gynecologic patients; however, as far as elderly patients are concerned, its incidence is 13.6% [3]. The most common cause of pyometra is malignant diseases of genital tract and the consequences of their treatment (radiotherapy. Other causes are benign tumors like leiomyoma, endometrial polyps, senile cervicitis, cervical occlusion after surgery, puerperal infections, and congenital cervical anomalies. Spontaneous rupture of the uterus is an extremely rare complication of pyometra. To our knowledge, only 21 cases of spontaneous perforation of pyometra have been reported in English literature since 1980. This paper reports an additional case of spontaneous uterine rupture.

  5. Bowel Perforation complicating an incarcerated inguinal hernia

    Adam Sigal


    Full Text Available History of present illness: A 51-year-old male presents complaining of increasing right groin pain and an enlarging bulge. Symptoms started as a “bubble” 6 weeks prior to presentation. One week prior to presentation, thinking the bulge was an abscess, the patient attempted to “pop” the bulge with a sewing needle, the needle became lodged in the site and he attempted retrieval with a second sewing needle, which also became lodged. No purulent material was obtained. The patient denied any nausea, vomiting or constipation as well as any fevers or urinary symptoms. His abdomen was soft, non-tender, non-distended with active bowel sounds. The groin exam demonstrated an incarcerated right inguinal hernia and cellulitis of the right hemiscrotum with associated induration and tenderness. Significant findings: The AP and lateral pelvis x-rays revealed two sewing needles, 60 mm in length, within the soft tissue over the anterior right lower hemipelvis. In addition, the AP view showed emphysema involving the right hemiscrotum (arrow, concerning for perforated bowel. Discussion: Groin hernias have a lifetime risk of 27% for men and 3% for women and the incidence increases with age.1 Groin hernias can be either direct or indirect, and inguinal or femoral. The distinction is made during surgery. Femoral hernias make up only 5% of groin hernias but are more common in women.1 Concerning complications include incarceration, in which a hernia cannot be reduced, and strangulation in which vascular compromise occurs.1 Incarcerated hernias often present with a painful, tender mass and are difficult to distinguish from strangulation. Patients with strangulation may present with fevers and peritonitis. The overlying skin may also be red.2 The percentage of patients presenting with strangulation varies by region. Western developed countries report only 1%-3% of patients presenting as surgical emergencies whereas in Africa the percentage can be as high as 26

    Full Text Available A 45 year old Caucasian man with a history of HIV/AIDS was admitted for septic shock secondary to right lower lobe community acquired pneumonia. The patient’s respiratory status continued to decline requiring emergency intubation in a non-ICU setting. Four laryngoscope intubation attempts were made including an inadvertent esophageal intubation. Subsequent CT imaging revealed a tracheal defect (Figure 1, red arrow with communication to the mediastinum and air around the trachea consistent with pneumomediastinum (Figure 2, orange arrow and figure 3, yellow arrow. Pneumopericardium (figure 4, blue arrow was also evident post-intubation. The patient’s hemodynamic status remained stable. Two days following respiratory intubation subsequent chest imaging revealed resolution of the pneumomediastinum and pneumopericardium and patient continued to do well without hemodynamic compromise or presence of subcutaneous emphysema. Post-intubation tracheal perforation is a rare complication of traumatic intubation and may be managed with surgical intervention or conservative treatment (1.

  7. Endoscopic muscularis excavation for subepithelial tumors of the esophagogastric junction originating from the muscularis propria layer. (United States)

    Zhang, Yu; Ye, Li-ping; Zhu, Lin-hong; Zhou, Xian-bin; Mao, Xin-li; Ding, Jin-xiu


    Because of complicating anatomic factors, endoscopic submucosal dissection is seldom performed in subepithelial tumors of the esophagogastric junction originating from the muscularis propria layer. This study was designed to evaluate the feasibility of endoscopic muscularis excavation for treating subepithelial tumors of the esophagogastric junction originating from the muscularis propria layer. Between December 2008 and December 2011, 68 patients with subepithelial tumors of the esophagogastric junction originating from the muscularis propria layer were treated with endoscopic muscularis excavation. Key steps of the procedure included the following: (1) injecting a mixture solution into the submucosal layer after making several dots around the tumor; (2) making a cross incision of the overlying mucosa, and excavating the tumor from the muscularis propria layer; (3) closing the artificial ulcer with clips after tumor removal. The mean tumor size was 16.2 mm (range 7-35 mm). Endoscopic muscularis excavation was successfully performed in 65 out of 68 cases (success rate 95.6 %). Pathological diagnosis of these tumors included leiomyoma (39 out of 68) and gastrointestinal stromal tumor (29 out of 68). Perforation occurred in seven patients (10.3 %). No massive bleeding or delayed bleeding occurred. The median follow-up period after the procedure was 23 months (range 6-42 months). No residual or recurrent tumor was detected and no stricture occurred in patients during the follow-up period. Endoscopic muscularis excavation is a safe, effective and feasible procedure for providing accurate histopathologic evaluation and curative treatment for subepithelial tumors of the esophagogastric junction originating from the muscularis propria layer.

  8. Endoscopic excavation for gastric heterotopic pancreas: an analysis of 42 cases from a tertiary center. (United States)

    Zhang, Yu; Huang, Qin; Zhu, Lin-hong; Zhou, Xian-bin; Ye, Li-ping; Mao, Xin-li


    Because of the difficulty associated with making an accurate diagnosis of gastric heterotopic pancreas (HP) before surgery, surgical resection is usually performed in suspected cases. However, this is an invasive procedure and prone to certain surgical complications. This study was designed to evaluate the feasibility of endoscopic excavation for gastric HP, as well as the value of endoscopic ultrasonography (EUS) in diagnosing gastric HP. Between January 2007 and January 2013, 42 consecutive patients with gastric HP were enrolled in this retrospective study. Key steps: (1) Injection of a solution (100 ml saline + 2 ml indigo carmine + 1 ml epinephrine) into the submucosal layer after making several dots around the lesion; (2) Incision of the mucosa outside the marker dots with a needle-knife, and then circumferential excavation until complete resection of the lesion; (3) Closure of the artificial ulcer with several clips after tumor removal. In this study, 18 cases (42.9%) were suspected as gastric HP (assessed by two experienced endoscopists before endoscopic excavation), 8 (19.0%) were suspected as gastrointestinal stromal tumors, 7 (16.7%) as gastric polyp, and the remaining 9 cases (21.4%) were still unknown. The mean procedure duration was 28.6 min. En bloc resection by endoscopic excavation was achieved in 40 cases (95.2%), and no massive bleeding, delayed bleeding, perforation, or other severe complication occurred in these patients. Among the 42 lesions, a tube echo could be detected in 11 cases by EUS. Those 11 cases were diagnosed as gastric HP by histopathology. Endoscopic excavation appears to be a safe and feasible procedure for accurate histopathologic evaluation and curative treatment in gastric HP. Use of EUS has some value in the diagnosis of gastric HP before the procedure

  9. Per-oral endoscopic myotomy (POEM): a new endoscopic treatment for achalasia. (United States)

    Miranda García, Pablo; Casals Seoane, Fernando; Gonzalez, Jean-Michel; Barthet, Marc; Santander Vaquero, Cecilio


    Per-oral endoscopic myotomy (POEM) is a new minimally invasive technique to treat achalasia. We performed a review of the literature of POEM with a special focus on technical details and the results obtained with this technique in patients with achalasia and other esophageal motility disorders. Thousands of POEM procedures have been performed worldwide since its introduction in 2008. The procedure is based on the creation of a mucosal entry point in the proximal esophagus to reach the cardia through a submucosal tunnel and then perform a myotomy of the muscular layers of the cardia, esophagogastric junction and distal esophagus, as performed in a Heller myotomy. The clinical remission rate ranges from 82 to 100%. Although no randomized studies exist and available data are from single-center studies, no differences have been found between laparoscopic Heller myotomy (LHM) and POEM in terms of perioperative outcomes, short-term outcomes (12 months) and long-term outcomes (up to three years). Procedure time and length of hospital stay were lower for POEM. Post-POEM reflux is a concern, and controversial data have been reported compared to LHM. The technique is safe, with no reported deaths related to the procedure and an adverse event rate comparable to surgery. Potential complications include bleeding, perforation, aspiration and insufflation-related adverse events. Thus, this is a complex technique that needs specific training even in expert hands. The indication for this procedure is widening and other motor hypercontractil esophageal disorders have been treated by POEM with promising results. POEM can be performed in complicated situations such as in pediatric patients, sigmoid achalasia or after failure of previous treatments. POEM is an effective treatment for achalasia and is a promising tool for other motor esophageal disorders. It is a safe procedure but, due to its technical difficulty and possible associated complications, the procedure should be performed

    Schmidt, Bruna Schwingel; Zaccara, Ivana Maria; Reis Só, Marcus Vinícius; Kuga, Milton Carlos; Palma-Dibb, Regina Guenka; Kopper, Patrícia Maria Poli


    Accidental root canal perforations are among the main complications of endodontic treatment. This study evaluated the influence of operating microscope (OM) in the marginal adaptation of mineral trioxide aggregate (MTA) (Angelus(®)) and glass ionomer (Vitremer) inserted into cervical perforations. Perforations were made in the cervical third of the buccal wall of the root canal in mandibular incisors. Next, the teeth were divided into four groups (N = 10): MG - MTA without OM; VG - Vitremer without OM; MOMG - MTA with OM; VOMG - Vitremer with OM. The perforations were sealed according to the group and the teeth were prepared for analysis by confocal laser scanning microscope. Images of perforation region (1,024×) were made and the gap presented by the materials was measured using the Image J program. LEXT OLS4100 three dimensional (3D) measuring laser microscope measured the volumetric misfit. Data of gap were analyzed by Kruskal-Wallis and Dunn's tests. Analysis of variance (ANOVA) and Tukey's tests compared the volumetric misfits. The results showed lower volume and gap in the interface dentin/material in VOMG compared to the other groups (P < 0.05). The use of OM improved the quality of cervical perforations sealed with Vitremer, being indicated in clinical situations of iatrogenic cervical perforations.

  11. Risk of surgical glove perforation in oral and maxillofacial surgery. (United States)

    Kuroyanagi, N; Nagao, T; Sakuma, H; Miyachi, H; Ochiai, S; Kimura, Y; Fukano, H; Shimozato, K


    Oral and maxillofacial surgery, which involves several sharp instruments and fixation materials, is consistently at a high risk for cross-contamination due to perforated gloves, but it is unclear how often such perforations occur. This study aimed to address this issue. The frequency of the perforation of surgical gloves (n=1436) in 150 oral and maxillofacial surgeries including orthognathic surgery (n=45) was assessed by the hydroinsufflation technique. Orthognathic surgery had the highest perforation rate in at least 1 glove in 1 operation (91.1%), followed by cleft lip and palate surgery (55.0%), excision of oral soft tumour (54.5%) and dental implantation (50.0%). The perforation rate in scrub nurses was 63.4%, followed by 44.4% in surgeons and first assistants, and 16.3% in second assistants. The odds ratio for the perforation rate in orthognathic surgery versus other surgeries was 16.0 (95% confidence interval: 5.3-48.0). The protection rate offered by double gloving in orthognathic surgery was 95.2%. These results suggest that, regardless of the surgical duration and blood loss in all fields of surgery, orthognathic surgery must be categorized in the highest risk group for glove perforation, following gynaecological and open lung surgery, due to the involvement of sharp objects.

  12. [Non-surgical treatment of perforations of the thoracic esophagus]. (United States)

    Slim, K; Elbaz, V; Pezet, D; Chipponi, J


    Thoracic oesophageal perforations are life-threatening conditions requiring immediate treatment. The type of treatment remains however controversial. The aim of this study was to evaluate the efficacy of the nonoperative management in this disease. Six patients were admitted in our surgical unit for thoracic oesophageal perforations during the study period. One perforation was spontaneous (Boerhaave's syndrome). One had complicated an oesophageal ulcer. Two were secondary to caustic lesions. Two were secondary to instrumental dilations. The diagnostic and therapeutic delay was tube suction, and total parenteral nutrition. There was no death in this group of patients. The mediastinitis healed in all cases. In the follow-up period two patients did not have nutritional restriction after healing. Three patients complained of oesophageal stenosis which required oesophageal replacement (n = 2) and dilation (n = 1). One neoplastic stenosis required an endoprosthesis. Nonoperative treatment is feasible and safe in selected cases of thoracic oesophageal perforations: perforations diagnosed early and confined to the mediastinum, instrumental perforations, and perforations diagnosed late but well tolerated.

    Sosa, Pablo; Dujovny, Manuel; Onyekachi, Ibe; Sockwell, Noressia; Cremaschi, Fabián; Savastano, Luis E


    The cerebellopontine angle is a common site for tumor growth and vascular pathologies requiring surgical manipulations that jeopardize cranial nerve integrity and cerebellar and brainstem perfusion. To date, a detailed study of vessels perforating the cisternal surface of the middle cerebellar peduncle-namely, the paraflocculus or parafloccular perforating space-has yet to be published. In this report, the perforating vessels of the anterior inferior cerebellar artery (AICA) in the parafloccular space, or on the cisternal surface of the middle cerebellar peduncle, are described to elucidate their relevance pertaining to microsurgery and the different pathologies that occur at the cerebellopontine angle. Fourteen cadaveric cerebellopontine cisterns (CPCs) were studied. Anatomical dissections and analysis of the perforating arteries of the AICA and posterior inferior cerebellar artery at the parafloccular space were recorded using direct visualization by surgical microscope, optical histology, and scanning electron microscope. A comprehensive review of the English-language and Spanish-language literature was also performed, and findings related to anatomy, histology, physiology, neurology, neuroradiology, microsurgery, and endovascular surgery pertaining to the cerebellar flocculus or parafloccular spaces are summarized. A total of 298 perforating arteries were found in the dissected specimens, with a minimum of 15 to a maximum of 26 vessels per parafloccular perforating space. The average outer diameter of the cisternal portion of the perforating arteries was 0.11 ± 0.042 mm (mean ± SD) and the average length was 2.84 ± 1.2 mm. Detailed schematics and the surgical anatomy of the perforating vessels at the CPC and their clinical relevance are reported. The parafloccular space is a key entry point for many perforating vessels toward the middle cerebellar peduncle and lateral brainstem, and it must be respected and protected during surgical approaches to the

  14. Gastric Perforation Associated with Tuberculosis: A Case Report

    Directory of Open Access Journals (Sweden)

    Richdeep S. Gill


    Full Text Available Gastric tuberculosis is a rare presentation of tuberculosis infection. Gastric perforation associated with tuberculosis is exceedingly rare with five previously published cases. We present a case of a male patient that developed presumed gastric tuberculosis secondary to pulmonary tuberculosis infection. He subsequently developed gastric perforation and sepsis, for which he was treated both surgically and medically. Despite ongoing antituberculosis treatment, the patient's condition worsened and the patient died secondary to multiorgan failure. This case highlights gastric perforation as a rare but devastating complication of pulmonary tuberculosis.

  15. Recurrent Pelvic Infections and Salpingitis after Perforated Appendicitis. (United States)

    Limberg, Jessica; Ginsburg, Howard; Lala, Shailee; Tomita, Sandra


    The effect of perforated appendicitis on the adnexa is an issue of concern and controversy. Long-term fertility studies have been conflicting. We present the case of a patient with chronic pelvic infections, salpingitis, and hydrosalpinx after perforated appendicitis. Magnetic resonance imaging was helpful in diagnosing a chronically obstructed fallopian tube, likely secondary to the dense adhesions from her previously treated perforated appendicitis. Salpingectomy relieved her symptoms of chronic pain and recurrent infections. Copyright © 2015 North American Society for Pediatric and Adolescent Gynecology. Published by Elsevier Inc.

    Kimbiris, D; Iskandrian, A S; Goel, I; Bemis, C E; Gehl, L; Owens, J; Segal, B L


    Transluminal coronary angioplasty may be associated with complications resulting from the dilatation catheter and inflation of the balloon. The most common complications are dissection, occlusion, and coronary spasm. We report an unusual complication of coronary artery perforation by the dilatation catheter resulting in acute pericardial tamponade. The complication was immediately recognized and confirmed by dye injection and hemodynamic measurements. Pericardiocentesis was performed, followed by successful coronary bypass surgery. The reasons for the perforation are unclear. We postulate that the acute angle of the perforated vessel was an important factor for this complication. The importance of a standby cardiac surgeon and operating room is emphasized.

  17. Oral antibiotics for perforated appendicitis is not recommended

    DEFF Research Database (Denmark)

    Alamili, Mahdi; Gögenur, Ismail; Rosenberg, Jacob


    In the majority of surgical departments in Denmark, the postoperative treatment for acute perforated appendicitis comprises three days of intravenous antibiotics. Recently, it has been proposed that such antibiotic regimen should be replaced by orally administered antibiotics. The aim of this paper...... was to give an overview of studies on acute perforated appendicitis with postoperative oral antibiotics. Five studies were found in a database search covering the 1966-2009 period. There is no evidence to support a conversion of the postoperative antibiotic regimen from intravenous to oral administration...... in patients with acute perforated appendicitis....

  18. A Rare Acute Abdomen Reason: Perforated Jejunal Diverticulitis

    Directory of Open Access Journals (Sweden)

    Oktay Karakose


    Full Text Available Jejunal diverticulosis is a rare case that is diagnosed incidental. Although it is generally asymptomatic, it can cause non-spesific symptoms like stomachache, nausea, diarrhoea, malabsorption, bleeding, obstruction and / or perforation. Perforated jejunal diverticulitis is a very rare acute abdomen cause. The acute complications of jejunal diverticulosis can be cause of significant morbidity and mortality especially in old patients. In this text, we report a 81 year old woman case that was operated emergently because of perforated jejunal diverticulitis and was lost in postoperation term because of multiple organ failure.

    Nikhil Ranjan


    Full Text Available A 19-year-old male patient underwent right percutaneous nephrolithotomy (PNL for right renal 1.5 × 1.5 cm lower pole stone. The procedure was completed uneventfully with complete stone clearance. The patient developed peritonitis and shock 48 h after the procedure. Exploratory laparotomy revealed a large amount of bile in the abdomen along with three small perforations in the gall bladder (GB and one perforation in the caudate lobe of the liver. Retrograde cholecystectomy was performed but the patient did not recover and expired post-operatively. This case exemplifies the high mortality of GB perforation after PNL and the lack of early clinical signs.

  20. Correlating the site of tympanic membrane perforation with Hearing loss

    Directory of Open Access Journals (Sweden)

    Ijaduola Taiwo G


    Full Text Available Abstract Background It is recognized that the size of tympanic membrane(TM perforation is proportional to the magnitude of hearing loss, however, there is no clear consensus on the effect of the location (site of the perforation on the hearing loss. Hence the study is set to investigate the relationship between the location of perforation on TM and hearing loss. Methods A cross-sectional prospective study of consecutive adult patients with perforated TM conducted in the ENT clinic of University College Hospital Ibadan between January 1st 2005 and July 31st 2006. Instruments used for data collection/processing include questionnaires, video and micro-otoscopy, Pure tone audiometer, image J and SPSS packages. Results Sixty-two patients (22-males, 40-females, aged 16–75 years (mean = 35.4 +/- 4 with 77 perforated ear drums were studied and 15(24.2% had bilateral TM perforations, 21 (33.9% right unilateral and 26(41.9% left unilateral. The locations of the TM perforations were 60(77.9% central, 6(9.6% antero-inferior, 4(5.2% postero-inferior, 4(5.2% antero-superior and 3(3.9% postero-superior respectively with sizes ranging from 1.51%–89.05%, and corresponding hearing levels 30 dB – 80 dB (59% conductive and 41% mixed. Fifty-nine percent had pure conductive hearing loss and the rest mixed. Hearing losses (dBHL increased with the size of perforations (P = 0.01, r = 0.05. Correlation of location of perforations with magnitude of hearing loss in acute TM perorations was (P = 0.244, r = 0.273 and for chronic perforations (p = 0.047 & r = 0.31. Conclusion The location of perforation on the tympanic membrane (TM has no effect on the magnitude of hearing loss in acute TM perforations while it is significant in chronic ones.

  1. External perforated Solar Screens for daylighting in residential desert buildings: Identification of minimum perforation percentages

    KAUST Repository

    Sherif, Ahmed


    The desert climate is endowed by clear sky conditions, providing an excellent opportunity for optimum utilization of natural light in daylighting building indoor spaces. However, the sunny conditions of the desert skies, in countries like Egypt and Saudi Arabia, result in the admittance of direct solar radiation, which leads to thermal discomfort and the incidence of undesired glare. One type of shading systems that is used to permit daylight while controlling solar penetration is " Solar Screens" Very little research work addressed different design aspects of external Solar Screens and their influence on daylighting performance, especially in desert conditions, although these screens proved their effectiveness in controlling solar radiation in traditional buildings throughout history.This paper reports on the outcomes of an investigation that studied the influence of perforation percentage of Solar Screens on daylighting performance in a typical residential living room of a building in a desert location. The objective was to identify minimum perforation percentage of screen openings that provides adequate illuminance levels in design-specific cases and all-year-round.Research work was divided into three stages. Stage one focused on the analysis of daylighting illuminance levels in specific dates and times, while the second stage was built on the results of the first stage, and addressed year round performance using Dynamic Daylight Performance Metrics (DDPMs). The third stage addressed the possibility of incidence of glare in specific cases where illuminance levels where found very high in some specific points during the analysis of first stage. The research examined the daylighting performance in an indoor space with a number of assumed fixed experimentation parameters that were chosen to represent the principal features of a typical residential living room located in a desert environment setting.Stage one experiments demonstrated that the screens fulfilled the

  2. External perforated window Solar Screens: The effect of screen depth and perforation ratio on energy performance in extreme desert environments

    KAUST Repository

    Sherif, A.


    In hot arid desert environments, the solar radiation passing through windows increases the cooling loads and the energy consumption of buildings. Shading of windows can reduce these loads. Unlike the woven solar screens, wooden solar screens have a thickness that provides selective shading properties. Perforated wooden solar screens were traditionally used for windows shading. Developing modern types of these shading systems can lead to significant energy savings. The paper addresses the influence of changing the perforation percentage and depth of these screens on the annual energy loads, hence defining the optimum depth/perforation configurations for various window orientations. Series of experiments were performed using the EnergyPlus simulation software for a typical residential building in the Kharga Oasis, located in the Egyptian desert. A range of perforation percentages and depths were tested. Conclusions prove that external fixed deep perforated solar screens could effectively achieve energy savings up to 30% of the total energy consumption in the West and South orientations. Optimum range of depths and perforation percentages were recommended. These are: 80-90% perforation rate and 1:1 depth/opening width ratio. These lighter and deeper solar screen configurations were found to be more efficient in energy consumption in comparison with the traditional ones. © 2012 Elsevier B.V. All rights reserved.

  3. Reuse of a Reversed "Bone Pad" to Perforate Incompletely Penetrated Burr Holes Created by Automatic-Releasing Cranial Perforators. (United States)

    Murai, Yasuo; Ishisaka, Eitaro; Tsukiyama, Atsushi; Nakagawa, Shunsuke; Matano, Fumihiro; Tateyama, Kojiro; Morita, Akio


    It can be difficult to make complete burr holes using a perforator with automatic releasing systems in cases of a soft diploe or thick calvarial bone. To demonstrate the utility of a flipped "bone pad" (BP) in recovery of penetration failure when using an automatic releasing perforator. For craniotomy or ventricular drainage, the first step is to make 1 or more burr holes using a craniotome. Neurosurgeons sometimes incompletely penetrate the skull using the latest tools. As a countermeasure for such cases, we have developed a simple and practical method. When making a perforation using a high-speed perforator, a round bone piece we call the BP is formed just above the dura. We pulled the BP from a completed burr hole, and placed the reversed BP in position at the bottom of the incompletely perforated burr hole. The BP acted as a new hard surface, preventing the automatic releasing system from activating, and allowed the burr hole to be completed by the craniotome without the need for additional tools. With this technique, we have successfully completed 6 out of 7 imperfectly perforated burr holes using a perforator with an automatic releasing system. There were no technique-related complications, such as plunging or dural laceration. The method has the advantage that the BP can be obtained without drilling an additional burr hole, and can be completed without the need for increasing cost, time, or instrument usage.

  4. Endoscopic submucosal dissection training with ex vivo human gastric remnants. (United States)

    Pham, David V; Shah, Anand; Borao, Frank J; Gorcey, Steven


    Endoscopic submucosal dissection (ESD) offers en bloc resection of early cancer or precancerous lesions, potentially saving patients from major organ resection, such as gastrectomy, colectomy, and esophagectomy. Japan now leads the world in ESD due to its high rate of gastric cancer. Western countries, with their lower gastric cancer rates, do not get as much experience with the technique. Training in ESD utilizing both in vivo and ex vivo porcine stomach has been shown to decrease rates of perforation and operative time. Both models can be prohibitively expensive or not generally available to the majority of endoscopists on a regular basis. This study describes the framework for using human gastric remnants from sleeve gastrectomy patients for ESD training. Patients undergoing sleeve gastrectomy for morbid obesity were consented for use of their gastric specimen before surgery. The specimen was weighed and measured by the pathologist and then used for ESD training. The specimen was mounted to a 15-mm laparoscopic port and secured using a pursestring suture. ESD was then performed through this port. We were able to successfully use this model to resect multiple marked out lesions in an en bloc fashion. Training using this model has improved our dissection times from approximately 2 h to 30 min for a 2-cm simulated lesion. ESD requires the endoscopist to perform a surgical dissection. Until now, development of these skills required intensive training on porcine models that are not widely available. We were able to create a method using the excised portion from sleeve gastrectomy patients, providing a more accessible and cost-effective model for ESD training and potentially other endoscopic therapeutic modalities.

  5. The DIEA branching pattern and its relationship to perforators: the importance of preoperative computed tomographic angiography for DIEA perforator flaps. (United States)

    Rozen, Warren M; Palmer, Kate P; Suami, Hiroo; Pan, Wei R; Ashton, Mark W; Corlett, Russell J; Taylor, G Ian


    Abdominal donor-site flaps based on the deep inferior epigastric artery (DIEA) are the most common flaps used in autologous breast reconstruction. With significant variation in the vascular anatomy of the DIEA, preoperative imaging is desirable. Computed tomographic angiography, recently described for this purpose, uniquely demonstrates the branching pattern of the DIEA. The authors sought to correlate the DIEA branching pattern to the location and course of perforators as a preoperative planning tool for perforator flaps. Forty-five cadaveric hemi-abdominal walls were used for contrast injection of the DIEA with subsequent radiographic imaging. The branching pattern on radiography was thus correlated to the location and intramuscular course of perforators, from the main DIEA trunk to the point of the penetrating rectus sheath. The DIEA branching pattern correlated closely with the course of perforators. A bifurcating (type II) branching pattern demonstrated a reduced transverse distance traversed by each perforator, whereas a trifurcating (type III) branching pattern demonstrated significantly greater transverse distances (p = 0.0002). Type I vessels were intermediate. Vessel branching type, however, displayed no significant correlation with the number of perforators (p = 0.56). The distances traversed by perforators were significantly reduced with a bifurcating branching pattern of the DIEA, particularly those originating from the lateral branch, and were greatest with a trifurcating branching pattern. Increased transverse distances correlate with greater rectus muscle sacrificed during perforator flap surgery. As computed tomographic angiography is the optimal modality for demonstrating this pattern preoperatively, the authors suggest its use for preoperative assessment in transverse rectus abdominis musculocutaneous and DIEA perforator flaps.

  6. Endoscopic prevention of post-endoscopic retrograde cholangiopancreatography pancreatitis. (United States)

    Lee, Tae Hoon; Park, Do Hyun


    Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is not an uncommon adverse event but may be an avoidable complication. Although pancreatitis of severe grade is reported in 0.1%-0.5% of ERCP patients, a serious clinical course may be lethal. For prevention of severe PEP, patient risk stratification, appropriate selection of patients using noninvasive diagnostic imaging methods such as magnetic resonance cholangiopancreatography or endoscopic ultrasonography (EUS), and avoidance of unnecessary invasive procedures, are important measures to be taken before any procedure. Pharmacological prevention is also commonly attempted but is usually ineffective. No ideal agent has not yet been found and the available data conflict. Currently, rectal non-steroidal anti-inflammatory drugs are used to prevent PEP in high-risk patients, but additional studies using larger numbers of subjects are necessary to confirm any prophylactic effect. In this review, we focus on endoscopic procedures seeking to prevent or decrease the severity of PEP. Among various cannulation methods, wire-guided cannulation, precut fistulotomy, and transpancreatic septostomy are reviewed. Prophylactic pancreatic stent placement, which is the best-known prophylactic method, is reviewed with reference to the ideal stent type, adequate duration of stent placement, and stent-related complications. Finally, we comment on other treatment alternatives, and make the point that further advances in EUS-guided techniques may afford useful PEP prophylaxis.

  7. Development of a Swine Benign Biliary Stricture Model Using Endoscopic Biliary Radiofrequency Ablation. (United States)

    Park, Jin Seok; Jeong, Seok; Kim, Joon Mee; Park, Sang Soon; Lee, Don Haeng


    The large animal model with benign biliary stricture (BBS) is essential to undergo experiment on developing new devices and endoscopic treatment. This study conducted to establish a clinically relevant porcine BBS model by means of endobiliary radiofrequency ablation (RFA). Endoscopic retrograde cholangiography (ERC) was performed on 12 swine. The animals were allocated to three groups (60, 80, and 100 W) according to the electrical power level of RFA electrode. Endobiliary RFA was applied to the common bile duct for 60 seconds using an RFA catheter that was endoscopically inserted. ERC was repeated two and four weeks, respectively, after the RFA to identify BBS. After the strictures were identified, histologic evaluations were performed. On the follow-up ERC two weeks after the procedure, a segmental bile duct stricture was observed in all animals. On microscopic examination, severe periductal fibrosis and luminal obliteration with transmural inflammation were demonstrated. Bile duct perforations occurred in two pigs (100 W, n = 1; 80 W, n = 1) but there were no major complications in the 60 W group. The application of endobiliary RFA with 60 W electrical power resulted in a safe and reproducible swine model of BBS.

  8. Reappraisal of endoscopic papillary balloon dilation for the management of common bile duct stones (United States)

    Lai, Kwok-Hung; Chan, Hoi-Hung; Tsai, Tzung-Jiun; Cheng, Jin-Shiung; Hsu, Ping-I


    Although endoscopic sphincterotomy (EST) is still considered as a gold standard treatment for common bile duct (CBD) stones in western guideline, endoscopic papillary balloon dilation (EPBD) is commonly used by the endoscopists in Asia as the first-line treatment for CBD stones. Besides the advantages of a technical easy procedure, endoscopic papillary large balloon dilation (EPLBD) can facilitate the removal of large CBD stones. The indication of EPBD is now extended from removal of the small stones by using traditional balloon, to removal of large stones and avoidance of lithotripsy by using large balloon alone or after EST. According to the reports of antegrade papillary balloon dilatation, balloon dilation itself is not the cause of pancreatitis. On the contrary, adequate dilation of papillary orifice can reduce the trauma to the papilla and pancreas by the basket or lithotripter during the procedure of stone extraction. EPLBD alone is as effective as EPLBD with limited EST. Longer ballooning time may be beneficial in EPLBD alone to achieve adequate loosening of papillary orifice. The longer ballooning time does not increase the risk of pancreatitis but may reduce the bleeding episodes in patients with coagulopathy. Slowly inflation of the balloon, but not exceed the diameter of bile duct and tolerance of the patients are important to prevent the complication of perforation. EPBLD alone or with EST are not the sphincter preserved procedures, regular follow up is necessary for early detection and management of CBD stones recurrence. PMID:25685263

  9. An Artificial Cadaveric Leg Blood Flow System for Endoscopic Vein Harvesting Simulation. (United States)

    Karras, Constantine L; DeDonato, Emily A; DiBartola, Kaitlin K; Zhao, Jin-Cheng

    Despite being the most common training model for endoscopic vein harvesting, cadaveric legs are limited by their absence of blood flow, resulting in a faded vascular appearance. Because the saphenous vein and the surrounding tissue seem less distinguishable, dissection of the saphenous vein and bipolar coagulation of its branches becomes increasingly inefficient and difficult. An inexpensive artificial blood flow system was developed to overcome this limitation. A cadaveric leg was thawed to a soft and yielding degree, and the saphenous vein was dissected medial and proximal to the medial malleolus. An artificial blood solution was prepared by dissolving 4% protein powder, red dye, and a contrast agent-for x-ray visualization-in saline. The solution was perfused through the saphenous vein and artery. The open ends of the vessels were temporarily clamped after the perfusion had been completed. Blood flow within the vessels was confirmed via angiography and endoscopic visualization of the leg's vessels. A bleeding effect was observed when the saphenous vein was perforated or when a vascular branch was transected. Conversely, a tight seal indicated successful bipolar coagulation of a branch, providing an objective, quantifiable assessment parameter. The artificial blood flow system helps overcome the limitations of the cadaveric leg, creating a more realistic and inexpensive model for endoscopic vein harvesting simulation training.

  11. Iatrogenic Colonic Perforation due to Computed Tomographic Colonography

    Directory of Open Access Journals (Sweden)

    Takashi Kato


    Full Text Available Although the complications of computed tomographic colonography (CTC are very rare, CTC is associated with potential risk of colonic perforation. In the present report we describe two cases of colonic perforation secondary to CTC. In the first case with ascending colonic carcinoma, insertion of a rigid double-balloon catheter caused direct rectal wall perforation. In the second case with obstructive colonic carcinoma, pneumoperitoneum developed due to automated carbon dioxide insufflation. Both patients were asymptomatic after examination and recovered without any complications. Based on the findings of the current cases, we recommend that a soft-tip catheter be used for CTC, and suggest that colonic perforation can occur even with automatic insufflation, depending on patient characteristics.

  12. Severe visual loss caused by ocular perforation during chalazion removal. (United States)

    Shiramizu, Kevin M; Kreiger, Allan E; McCannel, Colin A


    To report two cases of ocular perforation during chalazion removal procedures leading to severe vision loss. Observational case series. Two patients presented with unilateral decreased vision after chalazion removal procedures. Complete ophthalmologic examinations were performed. Examination revealed a cherry red spot and perforation site in the first patient. In the second patient, there was an intraocular gas bubble and ischemic retina. Local anesthetic injections for procedures such as chalazia removal can result in ocular perforation. We postulate that the intraocular injections led to extremely high pressures, compromising the blood supply to the retina and optic nerve. Anesthetic injections for all procedures, even chalazia removal, should be done with great caution. It is imperative to avoid injection if ocular perforation is suspected, as the high pressure may cause the majority of the visual morbidity.

  14. Colon perforation after esophagogastroduodenoscopy in an asymptomatic diverticulitis patient

    Directory of Open Access Journals (Sweden)

    Li-Wen Huang


    Full Text Available Esophagogastroduodenoscopy (EGD is regarded as a relatively safe procedure; however, it carries a very low incidence of severe adverse events. Perforation is a rare complication of EGD, and it may further lead to pneumoperitoneum or pneumoretroperitoneum. The occurrence of large bowel perforation after EGD is extremely rare, and it has never been reported in the international literature. Herein, we present a case of concurrence of pneumoperitoneum and pneumoretroperitoneum as a result of sigmoid perforation after EGD. In our case, the probable mechanism of the perforation may have stemmed from the excessive inflation of air that passed through the gastrointestinal tract to the sigmoid colon, causing the increased intraluminal pressure, and then prompting a healed asymptomatic diverticulitis leak again.

  19. Endoscopic subsurface imaging in tissues

    Energy Technology Data Exchange (ETDEWEB)

    Demos, S G; Staggs, M; Radousky, H B


    The objective of this work is to develop endoscopic subsurface optical imaging technology that will be able to image different tissue components located underneath the surface of the tissue at an imaging depth of up to 1 centimeter. This effort is based on the utilization of existing technology and components developed for medical endoscopes with the incorporation of the appropriate modifications to implement the spectral and polarization difference imaging technique. This subsurface imaging technique employs polarization and spectral light discrimination in combination with image processing to remove a large portion of the image information from the outer layers of the tissue which leads to enhancement of the contrast and image quality of subsurface tissue structures.

  20. Endoscopic approach to subepithelial lesions. (United States)

    Menon, Laila; Buscaglia, Jonathan M


    Endoscopy and endoscopic ultrasound (EUS) play a critical role in the detection and management of subepithelial lesions of the gastrointestinal tract. The most common subepithelial lesions detected by endoscopists are gastrointestinal stromal tumors (GISTs), leiomyomas, lipomas, granular cell tumors (GCTs), pancreatic rests and carcinoid tumors. These lesions can be classified based on unique histochemical staining and the gastrointestinal layer of origin. While the majority of the lesions are considered benign, some tumors such as GISTs and carcinoids have a strong propensity for malignant transformation. Therefore, appropriate endoscopic versus surgical management based on size and location is crucial in the prevention of malignant transformation and metastasis. In this review, we provide a systematic approach to the diagnosis, management and treatment of commonly encountered subepithelial lesions.

    Full Text Available Iatrogenic bladder injuries have been reported in the neonate during umbilical artery/vein catheterization, voiding cystourethrogram, urinary catheterizations, and overwhelming hypoxic conditions. Patients with iatrogenic bladder perforations can present with acute abdomen indicating urinary peritonitis, septic-uremic shock, or subtle symptoms like abdominal distension, pain, hematuria, uremia, electrolyte imbalances, and/or difficulty urinating. The following neonatal case report of perforated bladder includes a review of the signs, symptoms, diagnostic tools, and management of bladder injury in neonates.

  6. Perforated villous adenoma of the cecum: report of a case. (United States)

    Rothstein, R D; Shrager, J; Rombeau, J L


    Villous adenomas are common neoplasms of the colon, often causing anemia or hemoccult positive stools. Less typically, these lesions may result in abdominal pain, melena, obstruction, or change in bowel habits. Intussusception may occur, but this complication is unusual in adults. Spontaneous bowel perforation attributable to colonic polyps has not been previously reported. We present here the first reported case of an adenomatous polyp with bowel perforation and bladder involvement.

  9. Endoscopic cubital tunnel recurrence rates. (United States)

    Cobb, Tyson K; Sterbank, Patrick T; Lemke, Jon H


    Cubital tunnel syndrome is the second most common nerve entrapment in the upper extremity. There are no current publications concerning the recurrence rates after endoscopic cubital tunnel release. The purpose of this study is to evaluate the recurrence rate of endoscopic cubital tunnel release compared to published reports of recurrence following open cubital tunnel procedures. We reviewed 134 consecutive cases of endoscopic cubital tunnel release in 117 patients. There were 104 cases in 94 patients with greater than 3 months follow-up. The mean follow-up time was 736 days. They were grouped using Dellon's classification. Two literature control groups were used from published reports of recurrence rate following open cubital tunnel release. A recurrence was identified if the patient was symptom-free following surgery but had symptoms reappear 3 months or more after surgery as defined in the literature. Of the 104 cases, 92.31% had more than a 4-month follow-up. One case (0.96%) met the criteria for recurrence at 4 months postprocedure. Data were then compared to the literature control groups used from published reports of recurrence rates following open cubital tunnel release. Pooled, the combined controls had 22 of 180 cases (12.22%) with recurrences. The percentage of procedure recurrence varied significantly with p value equal to 0.0004. It is recognized that there is a lack of common classification and comparative analysis of these studies, but they do classify preoperative grading and recurrence similarly. We are 95% confident that our true recurrence rate is between 0.02% and 5.24% and that endoscopic cubital tunnel release has a recurrence rate, which is not higher than open cubital tunnel release literature controls.

  10. Endoscopic versus microscopic stapes surgery. (United States)

    Surmelioglu, Ozgur; Ozdemir, Suleyman; Tarkan, Ozgur; Tuncer, Ulku; Dagkiran, Muhammed; Cetik, Fikret


    The aim of this study to compare the outcomes and complications of endoscopic stapes surgery versus microscopic stapes surgery. This study involved patients who underwent stapedotomy at the Department of Otorhinolaryngology, Faculty of Medicine, Cukurova University between January 2012 and July 2014. The patients were divided into two groups. Patients in group I were operated with endoscope and patients in group II were operated with microscope. Pure tone audiometry was carried out in all patients preoperatively. Peroperative surgical findings, complications, and duration of surgery were noted and compared between the two groups. Air conduction and bone conduction thresholds were measured at frequencies of 500, 1000, 2000, and 4000Hz, and the mean (±SD) air-bone gap was noted. Mean preoperative air-bone gap was 36.9±6.8dB (23.3-50dB) in group I and 35.1±6dB (26.6-50dB) in group II. Mean postoperative air-bone gap was 9.3±7.1dB (0-30dB) in group I and 13.5±9.7dB (1.6-35dB) in group II. The difference in preoperative and postoperative air-bone gap between the two groups was statistically significant (p=0.023). Patients in group I did not complain of postoperative pain but this was felt in four patients in group II. The difference was statistically significant (p=0.045). Endoscopic stapes surgery has many benefits such as good visualization, and easy accessibility to the stapes, oval window niche, and facial nerve. Removal of the scutum and manipulation of the chorda tympani nerve are less frequent with the endoscopic technique. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

  11. Endoscopic Aspects of Gastric Syphilis

    Mariana Souza Varella Frazão


    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.

  12. Evaluation of Double Perforated Baffles Installed in Rectangular Secondary Clarifiers

    Directory of Open Access Journals (Sweden)

    Byonghi Lee


    Full Text Available Double perforated baffles in rectangular secondary clarifiers were studied to determine whether they contribute to producing high-quality effluents. The Computational Fluid Dynamics (CFD simulations indicated that bio-flocculation occurred at the front of the baffle and the longitudinal movement of the settled sludge was hampered whenever the clarifier had high inflow. Simulation results showed that the rectangular clarifier with the double perforated baffle produced an effluent with lower suspended solid (SS concentrations than the effluent from the clarifier without the baffle. To verify the simulation results, a double perforated baffle was installed in two of the 48 rectangular clarifiers in a 300,000 m3/d-capacity wastewater treatment plant. To study the effect of the baffle on solid removal, the effluent turbidity of the clarifier with and without the double perforated baffle was measured simultaneously. Experimental data showed that the double perforated baffle played a significant role in reducing effluent turbidity. The effluent turbidity reduction ratio with the baffle decreased when the Sludge Volume Index (SVI of the Mixed Liquor Suspended Solids (MLSS was below 100 mL/g. The overall average reduction ratio was 24.3% for SVI < 100 mL/g and 45.1% for SVI > 100 mL/g. The results of this study suggest that double perforated baffles must be installed in secondary rectangular clarifiers to produce high-quality effluent regardless of the operational conditions.

  13. [Microsurgical anatomy of perforating branches of anterior communicating artery]. (United States)

    Ego, H; N'Da, H; Viart, L; Foulon, P; Le Gars, D; Havet, E; Peltier, J


    The anterior communicating artery (ACoA) gives perforating branches to the optic chiasma, the hypothalamus and the corpus callosum. Perforating branches are variable (number, direction). Nevertheless, their knowledge is crucial during surgery of this area to spare injuries leading to ischemic post-operative complications. The objective was to update the anatomical knowledge about perforating branches of the ACoA. The study was led on a series of seven brains taken from human cadavers. An injection of latex neoprene was performed for every case. The region of interest was observed under operating microscope. Were examined: the length of the ACoA, its diameter, its orientation, its configuration and perforating branches (number and areas). Three cases on five presented with an anatomical variation at the level of the ACoA. The average length of AcoA was 2.1 millimeters (min: 2, max: 2.2). The average diameter of the ACoA was 1.67 mm (min: 1.1, max: 2.1). The average number of perforating branches was 4.2 (min: 2, max: 6). The presence of a median artery of the corpus callosum seemed to correlated with a low number of perforating branches. Branches supplying the optic chiasma seemed to be more numerous.

  14. Delayed Diagnosis of Pharyngeal Perforation following Exploding Tyre Blast Barotrauma. (United States)

    Field, Samantha M; Manjaly, Joseph G; Ramdoo, S Krishan; Jones, Huw A S; Tatla, Taran S


    Introduction. Pharyngoesophageal perforation secondary to barotrauma is a rare phenomenon that can have serious complications if identified late. It is challenging to detect due to nonspecific symptoms. We present a case in which detection proved difficult leading to delayed diagnosis. Case Report. A 27-year-old mechanic presented with haemoptysis, dysphonia, and odynophagia after a car tyre exploded in his face. Flexible nasoendoscopy (FNE) revealed blood in the pharynx, thought to represent mucosal haemorrhage. Initial treatment consisted of IV dexamethasone and antibiotics. After 3 days, odynophagia persisted prompting a CT scan. This revealed a defect in the posterior hypopharynx and surgical emphysema in the deep neck tissues. Contrast swallow confirmed posterior hypopharyngeal leak. NG feeding was commenced until repeated contrast swallow confirmed resolution of the defect. Discussion. Prompt nonsurgical management of pharyngoesophageal perforation has good outcomes but untreated perforation can have serious complications. FNE should be performed routinely, but only a contrast swallow can diagnose a functional perforation. Clinicians should have a high index of clinical suspicion when patients present with barotrauma and odynophagia. Patients should be kept nil by mouth until perforation has been excluded. Conclusion. When faced with cases of facial barotrauma, clinicians should have a low threshold for further imaging to exclude pharyngoesophageal perforation.

  16. Factors That Influence Perforator Thrombosis and Predict Healing Perforator Sclerotherapy for Venous Ulceration Without Axial Reflux (United States)

    Kiguchi, Misaki M.; Hager, Eric S.; Winger, Daniel G.; Hirsch, Stanley A.; Chaer, Rabih A.; Dillavou, Ellen D.


    OBJECTIVES Refluxing perforators contribute to venous ulceration. We sought to describe patient characteristics and procedural factors that (1) impact rates of incompetent perforator vein (IPV) thrombosis with ultrasound-guided sclerotherapy (UGS) and (2) impact the healing of venous ulcers (CEAP 6) without axial reflux. METHODS Retrospective review of UGS of IPV injections from 1/2010–11/2012 identified 73 treated venous ulcers in 62 patients. Patients had no other superficial/axial reflux and were treated with standard wound care and compression. Ultrasound was used to screen for refluxing perforators near ulcer(s), and these were injected with sodium tetradecyl sulfate or polidocanol foam and assessed for thrombosis at 2 weeks. Demographic data, comorbidities, treatment details and outcomes were analyzed. Univariate and multivariable modeling was performed to determine covariates predicting IPV thrombosis and ulcer healing. RESULTS 62 patients with active ulcers for an average of 28 months with compression therapy prior to perforator treatment had an average age of 57.1 years, were 55% male, 36% had a history of DVT and 30% had deep venous reflux. 32 patients (52%) healed ulcers, while 30 patients (48%) had non-healed ulcer(s) in mean follow-up of 30.2 months. Ulcers were treated with 189 injections, with average thrombosis rate of 54%. Of 73 ulcers, 43 ulcers healed (59%), and 30 ulcers did not heal (41%). Patients that healed ulcers had an IPV thrombosis rate of 69 % vs. 38% in patients who did not heal (Pulcer healing found complete IPV thrombosis was a positive predictor (P=.02), while large initial ulcer area was a negative predictor (P=.08). Increased age was associated with fewer ulcer recurrences (P=.05). Hypertension and increased follow-up time predicted increased ulcer recurrences (P=.04, P=.02). Calf vein thrombosis occurred after 3% (6/189) of injections. CONCLUSIONS Thrombosis of IPVs with UGS increases venous ulcer healing in a difficult patient

    Perforation of jejunal diverticulum is a rare complication. Here, we report a case of jejunal diverticulum penetration with surrounding ectopic pancreas. An 83-year-old female patient was admitted to our department with acute onset of severe abdominal pain lasting for half a day. Abdominal computed tomography showed outpouching of the small intestine that contained air/fluid, with multiple surrounding air bubbles in the mesentery of the small intestine. She was diagnosed with penetration of the small intestine, and an emergency laparotomy was indicated. The penetrated jejunal diverticulum was identified ~20-cm distal to the ligament of Treitz. Partial resection of the jejunum was performed, and her postoperative course was uneventful. The pathological findings confirmed diverticulum penetration into the mesentery and severe inflammation at the site, with surrounding ectopic pancreas. Furthermore, the pancreatic ducts were opened through the penetrated diverticulum. This rare case shows that the ectopic pancreas might have caused penetration of jejunal diverticulum owing to the pancreatic duct opening through the diverticulum.

    Gopal Lingam


    Full Text Available Purpose: To report a case series of penetrating injury complicated by occurrence of intraocular cilia. Methods: Retrospective analysis of charts of 11 eyes of 11 patients with penetrating injury and intraocular cilia, presenting between September 1978 and November 1998. Ten eyes underwent surgery for trauma-related problems such as cataract, vitritis, retinal detachment etc., at which time intraocular cilia were removed. One eye did not have surgery and continues to harbour cilia at the posterior perforation site. Results: Metallic wire was responsible for injury in 6 of 11 eyes with intraocular cilia. Five eyes had significant intraocular inflammation. The cilia were located in the anterior segment in 4 eyes; in the posterior segment in 6 eyes and in both in one eye. At the last follow up, 72.7% had 6/18 or better vision. Poor vision in the rest was due to recurrent retinal detachment (2 eyes and macular scarring (1 eye. Conclusion: Intraocular cilia are more commonly associated with injury by a metallic wire. The presentation and management of an injured eye does not seem to be influenced by the presence of cilia in the eye.

  19. Percutaneous endoscopic gastrojejunostomy for a patient with an intractable small bowel injury after repeat surgeries: a case report

    Full Text Available Abstract Introduction The management of intestinal injury can be challenging, because of the intractable nature of the condition. Surgical treatment for patients with severe adhesions sometimes results in further intestinal injury. We report a conservative management strategy using percutaneous endoscopic gastrojejunostomy for an intractable small bowel surgical injury after repeated surgeries. Case presentation A 78-year-old Japanese woman had undergone several abdominal surgeries including urinary cystectomy for bladder cancer. After this operation, she developed peritonitis as a result of a small bowel perforation thought to be due to an injury sustained during the operation, with signs consistent with systemic inflammatory response syndrome: body temperature 38.5°C, heart rate 92 beats/minute, respiratory rate 23 breaths/minute, white blood cell count 11.7 × 109/L (normal range 4-11 × 109/μL. Two further surgical interventions failed to control the leak, and our patient's clinical condition and nutritional status continued to deteriorate. We then performed percutaneous endoscopic gastrojejunostomy, and continuous suction was applied as an alternative to a third surgical intervention. With this endoscopic intervention, the intestinal leak gradually closed and oral feeding became possible. Conclusion We suggest that the technique of percutaneous endoscopic gastrojejunostomy combined with a somatostatin analog is a feasible alternative to surgical treatment for small bowel leakage, and is less invasive than a nasojejunal tube.

    Heuss, L T; Spalinger, R


    A 43-year-old woman with spastic tetraparesis, mental retardation and long-term tube feeding was admitted for a replacement of the PEG tube, 15 months after placement and regular use of her first feeding tube. New problems had occurred with local infection and a suspected leakage. The gastrostoma showed a local erythema and increased secretion of putrid fluids, furthermore a tendency to diarrhea had developed. Otherwise the abdomen was inconspicuous. All routinely achieved blood tests were normal. Gastroscopy revealed a mucosal scar with a small fistula instead of the expected tip of the PEG tube. A CT scan demonstrated displacement of the tip into the transverse colon. The displaced PEG tube was removed by colonoscopy. After laparoscopic occlusion of the colocutaneous fistula with a surgical stapler and clearing of further adhesions a new PEG was inserted endoscopically during the same operation with laparoscopic guidance through the pneumoperitoneum. The development of a colocutaneous fistula as a result of an unperceived perforation is a rare complication of a PEG placement. Despite of the notable mechanism that the tip of the tube erodes the gastric wall and penetrates into the adjacent colon, the clinic is often oligosymptomatic and can easily been missed. © Georg Thieme Verlag KG Stuttgart · New York.

  1. Peroral endoscopic myotomy (POEM): feasible as reoperation following Heller myotomy. (United States)

    Vigneswaran, Yalini; Yetasook, Amy K; Zhao, Jin-Cheng; Denham, Woody; Linn, John G; Ujiki, Michael B


    The purpose of this study was to demonstrate the feasibility of performing peroral endoscopic myotomy (POEM) in the management of recurrent achalasia after failed myotomy. Eight patients presented to our institution between October 2010 and June 2013 with recurrent/persistent symptoms after prior laparoscopic Heller myotomy. Three patients underwent redo laparoscopic Heller myotomy, and five patients consented to redo myotomy with POEM. Demographics were similar between the groups with exception of age (POEM 69.5 vs. laparoscopic Heller myotomy (LHM) 34.5, p = 0.003). Preoperative Eckardt scores, motility, and prior interventions were not significantly different. Three patients who underwent POEM and two who underwent laparoscopic Heller myotomy had prior fundoplication. There was one perforation identified after laparoscopic Heller myotomy and one patient with persistent subcutaneous emphysema after POEM. Both POEM and laparoscopic Heller myotomy demonstrated significant improvement in symptoms and Eckardt scores at average follow-up of approximately 5 months (p POEM is a feasible option for patients after failed myotomy even in the presence of prior fundoplication. The procedure can be performed safely using a similar technique as for primary myotomy with the exception of creating the myotomy laterally along the right side of the esophagus and lesser curvature avoiding the previous anterior myotomy.

  2. Endoscopic submucosal dissection using a novel grasping type scissors forceps. (United States)

    Akahoshi, K; Akahane, H; Murata, A; Akiba, H; Oya, M


    Endoscopic submucosal dissection (ESD) with a knife is a technically demanding procedure that is associated with a high complication rate. The shortcoming of this method is the difficulty in fixing the knife to the target lesion. This difficulty can lead to unexpected incision, resulting in major complications such as perforation and bleeding. To reduce the risk of complications related to ESD, we developed a new grasping type scissors forceps (GSF), which can grasp and incise the targeted tissue using an electrosurgical current. The ESD procedure using the GSF was carried out in an animal model (resected porcine stomachs in vitro). After marking the lesion and injecting a solution into the submucosa, the lesion was separated from the surrounding normal mucosa following complete incision around the lesion using the GSF. A piece of submucosal tissue was grasped and cut with the GSF using an electrosurgical current to achieve submucosal exfoliation. ESD using the GSF was carried out safely and easily without unintentional incision. ESD using GSF appears to be an easy, safe, and technically efficient method for resecting gastrointestinal neoplasms.

  3. [Identification of perforating vessels by augmented reality: Application for the deep inferior epigastric perforator flap]. (United States)

    Bosc, R; Fitoussi, A; Pigneur, F; Tacher, V; Hersant, B; Meningaud, J-P


    The augmented reality on smart glasses allows the surgeon to visualize three-dimensional virtual objects during surgery, superimposed in real time to the anatomy of the patient. This makes it possible to preserve the vision of the surgical field and to dispose of added computerized information without the need to use a physical surgical guide or a deported screen. The three-dimensional objects that we used and visualized in augmented reality came from the reconstructions made from the CT-scans of the patients. These objects have been transferred through a dedicated application on stereoscopic smart glasses. The positioning and the stabilization of the virtual layers on the anatomy of the patients were obtained thanks to the recognition, by the glasses, of a tracker placed on the skin. We used this technology, in addition to the usual locating methods for preoperative planning and the selection of perforating vessels for 12 patients operated on a breast reconstruction, by perforating flap of deep lower epigastric artery. The "hands-free" smart glasses with two stereoscopic screens make it possible to provide the reconstructive surgeon with binocular visualization in the operative field of the vessels identified with the CT-scan.

  4. Factors predicting clinical outcomes of endoscopic submucosal dissection in the rectum and sigmoid colon during the learning curve (United States)

    Agapov, Mikhail; Dvoinikova, Ekaterina


    Background and study aims: Colorectal endoscopic submucosal dissection (ESD) is associated with significant technical difficulty, long procedure time, and increased risk of complications, especially perforation. This study aimed to determine the factors associated with clinical results of ESD during the learning curve. Patients and methods: In total, 44 patients with sessile and flat rectal and sigmoid colon lesions underwent ESD from November 2009 to September 2013. The procedure time, resection method, tumor size, location, gross morphology, presence of fibrosis, histologic findings, rates of en bloc and piecemeal resections and perforation were analyzed. The ESD procedure was classified as technically difficult in the case of procedure time > 120 minutes and/or piecemeal resection. The whole study time was divided into two periods: first period: resections 1 – 22, second period: resections 23 – 44. Results: En bloc and R0 resection have been achieved in 84.1 % of lesions. The mean procedure time was 119.95 ± 11.22 minutes (range 25 – 360 minutes). Perforation was seen in five cases (11.4 %). A larger tumor size was a risk factor for difficult ESD (P = 0.0001). A finding of fibrosis was a risk factor for piecemeal ESD (P = 0.0074), and perforation (P = 0.0012). There was a high direct positive correlation between tumor size and operation time (r = 0.83, P < 0.0001, 0.95 and 0.99 confidence interval for rho 0.71 – 0.904). There was no significant difference between the first and second period in terms of mean procedure time, en bloc resection or complication rate. Conclusion: A larger tumor size was associated with technically difficult ESD. Severe submucosal fibrosis was a risk factor for both piecemeal resection and perforation. PMID:26135099

    Full Text Available Introduction: Perforation of the tympanic membrane primarily results from middle ear infections, trauma or iatrogenic causes. The perforation causes conductive hearing loss by reducing the surface area available for sound transmission to the ossicular chain. Objective: The objective was to analyze the characteristics of tympanic membrane perforations in relation to hearing loss and to determine the type and degree of hearing loss. Materials and methods: We analyzed audiometric, otoscopic findings and medical reports of 218 patients, 114 males (52.3% and 104 females (47.7%, aged 9 to 75 years (mean age of 47.9 years, examined during the period of November 2012 to October 2015. For statistical data analysis we used Chi-square test with level of significance p<0.05. Results: Most of the patients had unilateral perforations (89% with right ear predominance and involvement of two quadrants of pars tensa (37.2%. Mean air-bone gap was 23.9 dB. The largest air-bone gap was at frequency of 250 Hz. Most of the patients (73.1% had mixed hearing loss (p=0.032, and average hearing thresholds from 21 to 40 dB. Conclusion: Mean air-bone gap is largest at the lower frequencies, and decreases as frequency increases. Size of the perforation has effect on hearing loss. Mean air-bone gap increases with increasing size of the perforation. There is no big difference between the mean air-bone gap in posterior versus anterior perforations.

  6. Bladder perforation in a peritoneal dialysis patient

    M Ounissi


    Full Text Available The dysfunction of the catheter in peritoneal dialysis (PD is a frequent compli-cation. However, perforation of organs are rare, particularly that of the urinary bladder. This re-quires an early diagnosis and prompt treatment of patients. We report here the case of a 38-year-old woman having end-stage renal disease due to autosomal-dominant polycystic kidney disease treated by PD since November 2000. Three years later, she was treated for Staphylococcal peritonitis. Four months later, she presented with a severe urge to urinate at the time of the fluid exchanges. The biochemical analysis of the fluid from the bladder showed that it was dialysis fluid. Injection of contrast through the catheter demonstrated the presence of a fistula between the bladder and the peritoneal cavity. She underwent cystoscopic closure of the fistulous tract and the PD catheter was removed. Subsequently, the patient was treated by hemodialysis. One month later, a second catheter was implanted surgically after confirming the closure of the fistula. Ten days later, she presented with pain at the catheter site and along the tunnel, which was found to be swollen along its track. The injection of contrast produced swelling of the subcutaneous tunnel but without extravasation of the dye. PD was withdrawn and the patient was put back on hemodialysis. Bladder fistula is a rare complication in PD and diagnosis should be suspected when patient complains of an urge to pass urine during the exchanges, which can be confirmed by contrast study showing presence of dye in the bladder. PD may be possible after the closure of the fistula, but recurrence may occur.

    Abdoulhossein Davoodabadi


    Full Text Available Introduction: In Ramadan, healthy adult Muslims are obliged to fast. Prolonged fasting increase gastric acid and pepsin levels, which promote the risk of duodenal ulcer perforation (DUP. Effects of Ramadan fasting on DUP have not been thoroughly studied yet, and the limited number of studies investigating the impact of Ramadan fasting on DUP yielded discrepant results. This study aimed to evaluate DUP frequency during Ramadan 2011-2015 and compare it with other months. Methods: This cross-sectional study was performed in 82 patients undergoing surgery due to DUP during July 2011-September 2015. The demographics, history of addiction, use of nonsteroidal and antiinflammatory drugs, previous history of acid peptic disease, as well as complications and outcomes of treatment were recorded and analyzed, and the obtained results were compared between Ramadan and other lunar months. Results: The majority of patients were male (86.6%, 71 patients, with a mean age of 43.9±16.5 years (age range: 20-75 years. Male to female ratio was 6:1. Cases with less than 30 years of age were less frequent (22%, 18 patients. DUP was more frequent during Rajab with nine cases (11%, while during Ramadan, six cases were reported, the difference between Ramadan and other months regarding the incidence of DUP was not significant (P=0.7. Risk factors such as smoking (60% and addiction (44%; especially to crystal and crack were noted. Consumption of nonsteroidal antiinflammatory drugs in 20 (24% patients, and use of antacids in 17 (25% patients. Distribution of DUP in different blood types was as follows: O+=41%, A+=28%, B+=23%, AB=5%, and O-=3%; moreover, post-operative Helicobacter pylori antibody was present in 67% of the patients. Conclusion: Ramadan fasting did not escalate DUP incidence, and those with DUP risk factors can fast with the use of antacids.

    We have previously reported the feasibility of diagnostic and therapeutic peritoneoscopy including liver biopsy, gastrojejunostomy, and tubal ligation by an oral transgastric approach. We present results of per-oral transgastric splenectomy in a porcine model. The goal of this study was to determine the technical feasibility of per-oral transgastric splenectomy using a flexible endoscope. We performed acute experiments on 50-kg pigs. All animals were fed liquids for 3 days prior to procedure. The procedures were performed under general anesthesia with endotracheal intubation. The flexible endoscope was passed per orally into the stomach and puncture of the gastric wall was performed with a needle knife. The puncture was extended to create a 1.5-cm incision using a pull-type sphincterotome, and a double-channel endoscope was advanced into the peritoneal cavity. The peritoneal cavity was insufflated with air through the endoscope. The spleen was visualized. The splenic vessels were ligated with endoscopic loops and clips, and then mesentery was dissected using electrocautery. Endoscopic splenectomy was performed on six pigs. There were no complications during gastric incision and entrance into the peritoneal cavity. Visualization of the spleen and other intraperitoneal organs was very good. Ligation of the splenic vessels and mobilization of the spleen were achieved using commercially available devices and endoscopic accessories. Transgastric endoscopic splenectomy in a porcine model appears technically feasible. Additional long-term survival experiments are planned.

  10. Endoscopic cubital tunnel release: a systematic review. (United States)

    Smeraglia, Francesco; Del Buono, Angelo; Maffulli, Nicola


    Theoretical advantages of endoscopic cubital tunnel release are the short incision, lower risk of nerve damage, reduced manipulation of the nerve and possible faster recovery. We systematically searched Medline (PubMed), Web of Science and Scopus databases using the following keywords: 'endoscopic ulnar nerve', 'endoscopic cubital nerve', 'endoscopic ulnar compression' and 'endoscopic ulnar neuropathy'. Twenty-one studies were included in this review. The quality of the studies was assessed using the Coleman Methodological Score. Endoscopic release is effective for cubital tunnel entrapment and allows adequate visualization of the site of entrapment. There is a negative association between the severity of the compression and reported outcomes. Injury to the medial branch of the antebrachial cutaneous nerve is less frequent thanks to the limited dissection. The most frequent complication is the development of a hematoma. It is unclear whether ulnar nerve instability is a contraindication to simple decompression. The shorter time to return to work and the cosmetic appearance of the scar can be considered advantages of the endoscopic technique. There is a need to perform randomized clinical trials with common and validated scoring system with a longer duration of follow-up. The literature pertinent to endoscopic cubital tunnel release is lacking in the evaluation of the learning curve. Further investigations are necessary to assess the role of ulnar nerve instability. © The Author 2015. Published by Oxford University Press. All rights reserved. For permissions, please e-mail:

  15. Safety and efficacy of endoscopic excavation for gastric subepithelial tumors originating from the muscularis propria layer: results from a large study in China. (United States)

    Zhang, Yu; Ye, Li-Ping; Zhou, Xian-Bin; Mao, Xin-Li; Zhu, Lin-Hong; He, Bi-Li; Huang, Qin


    In this retrospective study, we investigated the safety and efficacy of endoscopic excavation of gastric subepithelial tumors (SETs) originating from the muscularis propria (MP) layer. Between November 2007 and June 2012, 212 patients with gastric SETs originating from the MP layer were treated via endoscopic excavation. The key procedures were: (1) injecting a mixture solution (100 mL saline+2 mL indigo carmine+1 mL epinephrine) into the submucosa around the tumor; (2) making a cross-incision of the mucosa and then excavating the tumor by the technique of endoscopic excavation. After the tumor was completely excavated from the MP layer, it was removed using a snare; (3) closing the artificial ulcer with clips. The mean diameter of the 212 tumors was 16.5 mm. Complete resection by endoscopic excavation was achieved in 204 cases (96.2%). The rate of complete resection was significantly higher for tumors 2 cm (91.9%) (P=0.035). Perforation occurred in 32 cases (15.1%), and massive bleeding occurred in 9 cases (4.2%) during the procedure. The rate of perforation was significantly higher for the fundus and the body than for antrum (21.5%, 11.5%, 0%, respectively; P=0.036), and also differed significantly in relation to histologic diagnosis (23.7% for gastrointestinal stromal tumors vs. 7.8% for leiomyoma; P=0.001). Histologic diagnosis showed that the density of gastrointestinal stromal tumors located in the fundus and the body of the stomach was significantly higher than in the antrum (44.1%, 51.9%, 13.3%, respectively; P=0.036). Endoscopic excavation is a safe and efficient method for resecting small (>3.5 cm) gastric SETs originating from the MP layer.

  16. Integrated biophotonics in endoscopic oncology (United States)

    Muguruma, Naoki; DaCosta, Ralph S.; Wilson, Brian C.; Marcon, Norman E.


    Gastrointestinal endoscopy has made great progress during last decade. Diagnostic accuracy can be enhanced by better training, improved dye-contrast techniques method, and the development of new image processing technologies. However, diagnosis using conventional endoscopy with white-light optical imaging is essentially limited by being based on morphological changes and/or visual attribution: hue, saturation and intensity, interpretation of which depends on the endoscopist's eye and brain. In microlesions in the gastrointestinal tract, we still rely ultimately on the histopathological diagnosis from biopsy specimens. Autofluorescence imaging system has been applied for lesions which have been difficult to morphologically recognize or are indistinct with conventional endoscope, and this approach has potential application for the diagnosis of dysplastic lesions and early cancers in the gastrointestinal tract, supplementing the information from white light endoscopy. This system has an advantage that it needs no administration of a photosensitive agent, making it suitable as a screening method for the early detection of neoplastic tissues. Narrow band imaging (NBI) is a novel endoscopic technique which can distinguish neoplastic and non-neoplastic lesions without chromoendoscopy. Magnifying endoscopy in combination with NBI has an obvious advantage, namely analysis of the epithelial pit pattern and the vascular network. This new technique allows a detailed visualization in early neoplastic lesions of esophagus, stomach and colon. However, problems remain; how to combine these technologies in an optimum diagnostic strategy, how to apply them into the algorithm for therapeutic decision-making, and how to standardize several classifications surrounding them. 'Molecular imaging' is a concept representing the most novel imaging methods in medicine, although the definition of the word is still controversial. In the field of gastrointestinal endoscopy, the future of

    An evaluation of the efficacy of endoscopic methods for the diagnosis and correction of surgical and immunological complications after retroperitoneal pancreas transplantation. From October 2011 to March 2015, 27 patients underwent simultaneous retroperitoneal pancreas-kidney transplantation (SPKT). Diagnostic oesophagogastroduodenoscopy (EGD) with protocol biopsy of the donor and recipient duodenal mucosa and endoscopic retrograde pancreatography (ERP) were performed to detect possible complications. Endoscopic stenting of the main pancreatic duct with plastic stents and three-stage endoscopic hemostasis were conducted to correct the identified complications. Endoscopic methods showed high efficiency in the timely diagnosis and adequate correction of complications after retroperitoneal pancreas transplantation. © 2017 John Wiley & Sons A/S.

  18. Endoscopic Thyroidectomy for Differentiated Thyroid Cancer

    Directory of Open Access Journals (Sweden)

    Yi Yang


    Full Text Available Endoscopic thyroidectomy is a relatively new approach in treating differentiated thyroid cancer. Since last decades, more and more endoscopic thyroidectomies have been performed. We review the indications and contraindications, methods, and postoperational complications of this surgical procedure. Lots of surgical approaches have been developed in endoscopic thyroidectomy for differentiated thyroid cancer. Compared to conventional thyroidectomy, scarless endoscopic thyroidectomy has a superior cosmetic result. And it also reduces the incidence of hypesthesia, paresthesia, or feelings of self-consciousness. However, the outcome depends, to a large extent, on the skill of the operator and the learning curve being relatively long. With the development of surgical equipments and skills, operation time and complications will be reduced. Indications of endoscopic thyroidectomy will be widened and it will be more and more performed.

    de Avila, Erica Dorigatti; Filho, José Scarso; de Oliveira Ramalho, Lizete Toledo; Real Gabrielli, Mario Francisco; Pereira Filho, Valfrido Antônio


    Autogenous bones are frequently used because of their lack of antigenicity, but good osteoconductive and osteoinductive properties. This study evaluated the biological behavior of perforated and nonperforated cortical block bone grafts. Ten nonsmoking patients who required treatment due to severe resorption of the alveolar process and subsequent implant installation were included in the study. The inclusion criteria was loss of one or more teeth; the presence of atrophy of the alveolar process with the indication of reconstruction procedures to allow rehabilitation with dental implants; and the absence of systemic disease, local infection, or inflammation. The patients were randomly divided into two groups based on whether they received a perforated (inner surface) or nonperforated graft. After a 6-month healing period, a biopsy was performed and osseointegrated implants were installed in the same procedure. Fibrous connective tissue was evident at the interface in patients who received nonperforated grafts. However, full union between the graft and host bed was visible in those who had received a perforated graft. We found that cortical inner side perforations at donor sites increased the surface area and opened the medullary cavity. Our results indicate an increased rate of graft incorporation in patients who received such perforated grafts.

    Mente, Johannes; Hage, Nathalie; Pfefferle, Thorsten; Koch, Martin Jean; Geletneky, Beate; Dreyhaupt, Jens; Martin, Nicolas; Staehle, Hans Joerg


    The use of biocompatible materials like mineral trioxide aggregate (MTA) may improve the prognosis of teeth with root perforations. The treatment outcome of root perforations repaired between 2000 and 2006 with MTA was investigated. Twenty-six patients received treatment with MTA in 26 teeth with root perforations. Treatment was performed by supervised undergraduate students (29%), general dentists (52%), or dentists who had focused on endodontics (19%). Perforation repair by all treatment providers was performed using a dental operating microscope. Calibrated examiners assessed clinical and radiographic outcome 12 to 65 months after treatment (median 33 months, 81% recall rate). Pre-, intra-, and postoperative information relating to potential prognostic factors was evaluated. Of 21 teeth examined, 18 teeth (86%) were classified as healed. None of the analyzed potential prognostic factors had a significant effect on the outcome. MTA appears to provide a biocompatible and long-term effective seal for root perforations in all parts of the root. Copyright 2010 American Association of Endodontists. Published by Elsevier Inc.

  2. The research progress of acute small bowel perforation

    Directory of Open Access Journals (Sweden)

    Rudolf Schiessel


    Full Text Available This article reviews the various aetiologies of small bowel perforations and their management. In addition to the well-known aetiologies such as trauma, inflammation and circulatory disorders, several new causes of small bowel perforation have been described in recent years. The spectrum reaches from iatrogenic perforations during laparoscopic surgery or enteroscopies to drug-induced perforations with new anticancer agents. The management of small bowel perforations requires a concept consisting of the safe revision of the leaking bowel and the treatment of the peritonitis. Depending on the local situation and the condition of the patient, several treatment options are available. The surgical management of the bowel leak can range from a simple primary closure to a delayed restoration of bowel continuity. When the condition of the bowel or patient is frail, the risk of a failure of a closure or anastomosis is too high, and the exteriorization of the bowel defect as a primary measure is a safe option. The treatment of the peritonitis is also dependent on the condition of the patient and the local situation. Early stages of peritonitis can be treated by a simple peritoneal lavage, either performed by laparoscopy or laparotomy. Severe forms of peritonitis with multi-organ failure and an abdominal compartment syndrome need repeated peritoneal revisions. In such cases, the abdomen can only be closed temporarily. Different technical options are available in order to overcome the difficult care of these patients.

  3. Diagnosing perforated appendicitis in pediatric patients: a new model. (United States)

    van den Bogaard, Veerle A B; Euser, Sjoerd M; van der Ploeg, Tjeerd; de Korte, Niels; Sanders, Dave G M; de Winter, Derek; Vergroesen, Diederik; van Groningen, Krijn; de Winter, Peter


    Studies have investigated sensitivity and specificity of symptoms and tests for diagnosing appendicitis in children. Less is known with regard to the predictive value of these symptoms and tests with respect to the severity of appendicitis. The aim of this study was to determine the predictive value of patient's characteristics and tests for discriminating between perforated and nonperforated appendicitis in children. Pediatric patients who underwent an appendectomy at Spaarne Hospital Hoofddorp, the Netherlands, between January 1, 2009 and December 31, 2013, were included. Baseline patient's characteristics, history, physical examination, laboratory data and results of ultrasounds were collected. Univariate and multivariate logistic regressions were used to determine predictors of perforation. In total, 375 patients were included in this study of which 97 children (25.9%) had significant signs of perforation. Univariate analysis showed that age, duration of complaints, temperature, vomiting, CRP, WBC, different findings on ultrasound and the diameter of the appendix were good predictors of a perforated appendicitis. The final multivariate prediction model included temperature, CRP, clearly visible appendix and free fluids on ultrasound and diameter of the appendix and resulted in an area under the curve (AUC) of 0.91 showing sensitivity and specificity of respectively 85.2% and 81.2%. This prediction model can be used for identification of 'high-risk' children for a perforated appendicitis and might be helpful to prevent complications and longer hospitalization by bringing these children to theater earlier.

  4. Tenons Patch Graft in the Management of Large Corneal Perforations. (United States)

    Korah, Sanita; Selvin, Satheesh S T; Pradhan, Zia S; Jacob, Pushpa; Kuriakose, Thomas


    To describe a technique to manage corneal perforations between 3 and 6 mm in size using autologous Tenons tissue with cyanoacrylate glue and a bandage contact lens. A thin layer of Tenons capsule harvested from the patient's own eye is used to seal the perforation and act as a scaffold. The Tenons patch graft is spread over the perforation and held in place by the application of cyanoacrylate glue. A bandage contact lens is then placed on the eye. A 6-year retrospective review of 28 patients who underwent this procedure was performed. One patient was lost to follow-up. Of the 27 patients who were followed up, 20 healed completely, with an adherent leucoma and preservation of the anterior chamber. The condition of one patient (with a perforated Pseudomonas corneal ulcer) progressively worsened despite maximum medical therapy and had to undergo evisceration. This procedure makes use of easily available autologous Tenons tissue in patients with corneal perforations too large to be managed with cyanoacrylate glue alone, to preserve eyeball morphology. A corneal transplant can then be done when the cornea has healed.

  5. [Treatment of venous trophic ulcers, using echoscleroobliteration of perforant veins]. (United States)

    Rusyn, V I; Korsak, V V; Boldizhar, P O; Borsenko, M I; Mytrovka, B A


    In 36 patients, suffering trophic ulcers on a chronic venous insufficiency background in a decompensated stage (C6 in accordance to CEAP), echoscleroobliteration of perforant veins, using a "foam-form" method in accordance to Tessari, was performed. In 29 patients postrombophlebitic syndrome in incomplete recanalization stage was diagnosed, in 7 recurrence of varicose disease of the lower extremities. In all the patients during echoscleroobliteration there was possible to obliterate the insufficient perforant veins, in 3 patients two perforant veins were obliterated in each of them. In a one week a pathological blood flow along perforant veins, in accordance to data of ultrasound duplex scanning, was absent. This effect lasted during 6 mo in 29 (80.6%) patients. In 25 (69.4%) patients a trophic ulcers healing was achieved in 1 - 3 mo. In a one year in 30 (83.3%) patients a stable obliteration was noted, in 3 (8.3%) - partial recanalization, in 3 (8.3%) - complete recanalization of perforant veins.

  6. Colonic perforation as an unusual manifestation of Behcet's disease

    Directory of Open Access Journals (Sweden)

    Tomić-Lučić Aleksandra


    Full Text Available Introduction. Behcet's disease is multisystemic vasculitis which affects vein and artery blood vessels. Intestinal perforation rarely occurs as clinic manifestation in as litle as 1% of patients. The transverse colon is the most infrequent site of perforation. We presented a patient diagnosed with Behcet's disease who underwent both surgical and conversative treatment due to perforation of the colon. Case report. A 34-year-old patient was admitted to the hospital with fever, aphthous ulcerations on oral mucosa and genitals and bilateral uveitis. On the basis of clinical symptoms and the International Criteria developed in 1990 Behcet's disease was diagnosed. During the next few days the patient developed erythema nodosum, diarrheic syndrome and acute abdominal symptoms due to perforation of the transverse colon. An emergent laparotomy was undertaken involving resection of a perforated segment of the colon, and bipolar colostomy on the left side of abdomen. Following the surgery the patient was treated except for antibiotics with three successive pulse doses of methylprednisolone (500 mg/daily and cyclophosphamide (15 mg/kg. The treatment was continued by gradual decrease in the close of the corticosteroid (perorally and by cyclophosphamide first with monthly doses (5 monthly pulse doses of 15 mg/kg cyclophosphoamide, and then with 3-month doses (totally 6 doses up to totally 12 g. Conclusion. The therapy with pulse doses of methylprednisolone combined with pulse doses of cyclophosphamide was very effective in the reported case with the complex clinical manifestations leading to resolution of gastrointenstinal, ocular and orogenital lesions.

  7. [Anterolateral thigh perforator flaps for facial reconstruction after tumour surgery]. (United States)

    Gaggl, Alexander; Bürger, Heinz; Lesnik, Gerald; Müller, Ernst; Chiari, Friedrich


    Individual flap design and minor donor site morbidity are main criteria in the treatment of facial defects after tumour surgery. Microvascular perforator flaps seem to follow these criteria well. In the following study our experiences with microvascular anterolateral thigh perforator flaps (ALTPF) in reconstruction of the face following ablative tumour surgery are described and discussed in comparison to the present literature. In 19 patients with squamous cell carcinomas of the floor of the mouth (8), the cheek (6) or the mandible (5) of stadium T3 or T4 ablative tumour surgery followed by reconstruction was performed. For covering the soft tissue defects 19 ALTPF were used. In the five patients with carcinomas of the mandible a microvascular iliac crest transplant was combined with the anterolateral thigh perforator flap for complete chin reconstruction. In one patient an intraoperative dissection of the perforator vessels happened. In all other patients surgery and postoperative period was free of complications. Five patients had minor second surgery for aesthetic of functional reasons. At the end there were good aesthetic and functional results in every patient. The anterolateral thigh perforator flap is of great advantage in reconstruction of the face after tumour surgery. Individual designing, central and save perfusion, easy to be controlled, and a low incidence of donor site morbidity are their main advantages.

  8. Rare occupational cause of nasal septum perforation: Nickel exposure

    Directory of Open Access Journals (Sweden)

    Ertugrul Cagri Bolek


    Full Text Available Many etiologies are held accountable for nasal septum perforations. Topical nasal drug usage, previous surgeries, trauma, nose picking, squamous cell carcinoma, some rheumatological disorders such as granulomatosis with polyangiitis (Wegener granulomatosis, some infectious diseases such as syphilis and leprosy are among the causes of the perforations. Occupational heavy metal exposures by inhalation rarely may also cause nasal septum perforation. Here, we present a 29-year-old patient without any known diseases, who is a worker at a metallic coating and nickel-plating factory, referred for investigation of his nasal cartilage septum perforation from an otorhinolaryngology clinic. The patient questioning, physical examination and laboratory assessment about rheumatic and infectious diseases were negative. There was a metallic smell in the breath during the physical examination. The analysis showed serum nickel level at 31 μg/l and urine nickel at 18 μg/l (84.11 μg/g creatinine. Other possible serum and urine heavy metal levels were within normal ranges. Nickel exposure is usually together with other heavy metals (chromium or cadmium, it is rarely alone. Nickel ingested by inhalation usually leads to respiratory problems such as reduced olfactory acuity, ulcers, septum perforation or tumors of the nasal sinuses. This case demonstrates the importance of occupational anamnesis and awareness of diagnosis. Int J Occup Med Environ Health 2017;30(6:963–967

  9. Perforated Meckel's diverticulitis complicating active Crohn's ileitis: a case report

    Directory of Open Access Journals (Sweden)

    Schwenter Frank


    Full Text Available Abstract Introduction In Crohn's disease, the extension of active terminal ileitis into a Meckel's diverticulum is possible, but usually has no impact on clinical decision-making. We describe an original surgical approach in a young woman presenting with a combination of perforated Meckel's diverticulitis and active Crohn's ileitis. Case presentation We report the case of a 22-year-old woman with Crohn's disease, who was admitted for abdominal pain, fever and diarrhoea. CT scan demonstrated active inflammation of the terminal ileum, as well as a fluid collection in the right iliac fossa, suggesting intestinal perforation. Laparoscopy was performed and revealed, in addition to extensive ileitis, a 3 × 3 cm abscess in connection with perforated Meckel's diverticulitis. It was therefore possible to avoid ileocaecal resection by only performing Meckel's diverticulectomy; pathological examination of the surgical specimen revealed the presence of transmural inflammation with granulomas and perforation of the diverticulum at its extremity. Conclusion Crohn's disease of the ileum may be responsible for Meckel's diverticulitis and cause perforation which, in this case, proved to be a blessing in disguise and spared the patient an extensive small bowel resection.

  10. Perforated duodenal ulcer: a rare complication of deferasirox in children. (United States)

    Yadav, Sunil Kumar; Gupta, Vipul; El Kohly, Ashraf; Al Fadhli, Wasmi


    Duodenal ulcer perforation in pediatric age group is an uncommon entity; hence, it is not usually considered in the differential diagnosis of acute abdomen in these patients. It is important for the emergency physician to consider perforated peptic ulcer in the differential diagnosis of children presenting with acute abdominal pain, gastrointestinal bleeding, or shock. We report a 6½-year-old male child with thalassemia major who presented to emergency room with an acute abdomen and shock, who was subsequently found to have a perforated duodenal ulcer, probably related to use of oral chelating agent, deferasirox. Although, gastrointestinal symptoms like nausea, vomiting, and abdominal pain has been mentioned as infrequent adverse event in the scientific product information of deferasirox, in our current knowledge this is the first case report of perforated duodenal ulcer after oral deferasirox. The severity of this event justifies the reporting of this case. This patient had an atypical presentation in that there were no signs or symptoms of peptic ulcer disease before perforation and shock he was successfully managed with open surgery after initial resuscitation and stabilization of his general condition.

  11. Large balloon dilation post endoscopic sphincterotomy in removal of difficult common bile duct stones: a literature review. (United States)

    Rouquette, Olivier; Bommelaer, Gilles; Abergel, Armando; Poincloux, Laurent


    Endoscopic sphincterotomy (ES) is the standard therapy in common bile duct (CBD) stones extraction. Large stones (≥ 12 mm) or multiple stones extraction may be challenging after ES alone. Endoscopic sphincterotomy followed by large balloon dilation (ESLBD) has been described as an alternative to ES in these indications. Efficacy, safety, cost-effectiveness and technical aspects of the procedure have been here reviewed. PubMed and Google Scholar search resulted in forty-one articles dealing with CBD stone extraction with 12 mm or more dilation balloons after ES. ESLBD is at least as effective as ES, and reduces the need for additional mechanical lithotripsy. Adverse events rates are not statistically different after ESLBD compared to ES for pancreatitis, bleeding and perforation. However, particular attention should be paid in patients with CBD strictures, which is identified as a risk factor of perforation. ESLBD is slightly cost-effective compared to ES. A small sphincterotomy is usually performed, and may reduce bleeding rates compared to full sphincterotomy. Dilation is performed with 12-20 mm enteral balloons. Optimal inflation time is yet to be determined. The procedure can be performed safely even in patients with peri-ampullary diverticula and surgically altered anatomy. ESLBD is effective and safe in the removal of large CBD stones, however, small sphincterotomy might be preferred and CBD strictures should be considered as a relative contraindication.

  12. Endoscopic retrieval of multiple fragmented gastric bamboo chopsticks by using a flexible overtube. (United States)

    Chang, Jia-Jang; Yen, Cho-Li


    This is a rare case of a patient with mental disorder, who ingested nineteen pieces of fragmented bamboo chopsticks. We managed the multiple gastric foreign bodies with a sclerotherapy overtube, and these multiple fragmented bamboo chopsticks were retrieved successfully using the endoscopic method. There were only multiple erosions with hemorrhage over the mucosa of fundus and body of stomach, no fragments adhered or perforated through the gastric wall. The mucosa of esophagus was intact. The patient tolerated the procedure well and without any major complications. Multiple sharp elongated gastric foreign bodies can be successfully and safely retrieved by using protective sheath of oropharynx without assistance with laparoscopy or surgical intervention. This renders an option for the endoscopists to manage multiple elongated gastric foreign bodies.

  13. Novel Endoscopic Management of Obesity (United States)

    Dargent, Jerome


    Endoscopic procedures have been well-documented in the obesity field, but have not yet reached a sufficient level of evidence as stand-alone methods for treating obesity. It is unclear if they should take over. Although expanding, the array of bariatric surgical techniques does not fully meet the current needs, and there are not enough resources for increasing surgery. Surgery is avoided by a majority of patients, so that less aggressive procedures are necessary. For the time being, relevant endoscopic methods include intra-gastric balloons, gastric partitioning (Endo-plication), and the metabolic field (Endo-barrier). Surgical novelties and basic research are also important contributors owing to their potential combination with endoscopy. Conditions have been listed for implementation of bariatric endoscopy, because innovation is risky, expensive, and faces ethical challenges. A scientific background is being built (e.g., hormonal studies). Some techniques require additional study, while others are not ready but should be priorities. Steps and goals include the search for conceptual similarities and the respect of an ethical frame. Minimally invasive bariatric techniques are not ready for prime time, but they are already being successful as re-do procedures. A time-frame for step-strategies can be defined, and more investments from the industry are mandatory. PMID:26855921

  14. Perforated jejunal diverticulum: a rare case of acute abdomen (United States)

    Sehgal, Rishabh; Cheung, Cherry X.; Hills, Tristram; Waris, Aqueel; Healy, Donagh; Khan, Tahir


    Jejunal pseudo-diverticulosis is a rare acquired herniation of the mucosa and submucosa through weakened areas of the muscularis mucosa of the mesenteric aspect of the bowel. They are asymptomatic in the majority of cases; however, they can present with a wide spectrum of non-specific symptoms such as chronic abdominal discomfort, postprandial flatulence, diarrhoea, malabsorption and steattorhoea. In up to 15% of cases, more serious acute complications may arise such as the development of intestinal obstruction, haemorrhage or as in our case, localized peritonitis secondary to perforation. Perforation carries an overall mortality rate of up to 40% and exploratory laparotomy followed by copious lavage with segmental resection and primary anastomosis remains the mainstay of managing such sequalae of jejunal pseudo-diverticulosis. Our case report highlights the importance of maintaining a high clinical suspicion of a perforated jejunal diverticulum in an elderly patient presenting with an acute abdomen. PMID:27765806

  15. Acoustic Liner Drag: Measurements on Novel Facesheet Perforate Geometries (United States)

    Howerton, Brian M.; Jones, Michael G.


    Interest in characterization of the aerodynamic drag of acoustic liners has increased in the past several years. This paper details experiments in the NASA Langley Grazing Flow Impedance Tube to quantify the relative drag of several perforate-over-honeycomb liner configurations at flow speeds of centerline flow Mach number equals 0.3 and 0.5. Various perforate geometries and orientations are investigated to determine their resistance factors using a static pressure drop approach. Comparison of these resistance factors gives a relative measurement of liner drag. For these same flow conditions, acoustic measurements are performed with tonal excitation from 400 to 3000 hertz at source sound pressure levels of 140 and 150 decibels. Educed impedance and attenuation spectra are used to determine the impact of variations in perforate geometry on acoustic performance.

  16. Neovaginal perforation following sexual intercourse in a transsexual patient. (United States)

    Deliktas, Hasan; Ozcan, Onder; Cullu, Nesat; Erdogan, Omer


    Neovaginal perforation can develop following sexual intercourse in patients that have undergone male to female gender reassignment surgery. In such cases urinary tract symptoms may mimic acute cystitis and acute pyelonephritis. A 33-year old white transsexual patient presented to the emergency department with dysuria, hematuria, difficulty urinating, widespread groin pain, bilateral side pain, clear vaginal discharge, abdominal pain, and nausea 2-3 h after sexual intercourse. Abdominal tomography showed fluid around the vaginal cuff and air throughout the abdomen. Vaginography showed contrast leaking to the abdomen from the vaginal cuff. The patient was considered as vaginal perforation and admitted to clinic. Vaginal perforation should be considered in transsexual patients that develop urinary system symptoms following sexual intercourse. Such cases were treated medically without the need surgery.

  17. Computational analysis of acoustic transmission through periodically perforated interfaces

    Directory of Open Access Journals (Sweden)

    Rohan E.


    Full Text Available The objective of the paper is to demonstrate the homogenization approach applied to modelling the acoustic transmission on perforated interfaces embedded in the acoustic fluid. We assume a layer, with periodically perforated obstacles, separating two half-spaces filled with the fluid. The homogenization method provides limit transmission conditions which can be prescribed at the homogenized surface representing the "limit" interface. The conditions describe relationship between jump of the acoustic pressures and the transversal acoustic velocity, on introducing the "in-layer pressure" which describes wave propagation in the tangent directions with respect to the interface.This approach may serve as a relevant tool for optimal design of devices aimed at attenuation of the acoustic waves, such as the engine exhaust mufflers or other structures fitted with sieves and grillages. We present numerical examples of wave propagation in a muffler-like structure illustrating viability of the approach when complex 3D geometries of the interface perforation are considered.

  19. A simple prognostic scoring system for typhoid ileal perforation peritonitis. (United States)

    Singh, Hemant; Mishra, Arpan; Sharma, Dhananjaya; Somashekar, Uday


    The increasing awareness of the worse than expected outcome after typhoid ileal perforation (TIP) prompted us to prospectively prognosticate patients with the help of the Jabalpur prognostic score (JPS), a simplified scoring system for peptic perforation peritonitis (PPP). Eighty-two consecutive patients with TIP were studied from May 2005 to August 2008 in the Department of Surgery, NSCB Government Medical College, Jabalpur (MP), India. Six parameters used in the JPS were recorded: age, heart rate, mean blood pressure, serum creatinine, any co-morbid illness and perforation-operation interval. JPS correlated with morbidity and mortality in TIP patients and, as the score increased, so did the morbidity and mortality. Survivors had a significantly lower mean score (3.86 ± 2.23) than non-survivors (7.94 ± 3.6; P PPP patients. JPS can be easily modified for TIP (JPS-TIP) and can be easily used for its prognostication.

  20. Distal thoracic oesophageal perforation secondary to blunt trauma: Case report

    Directory of Open Access Journals (Sweden)

    Tandon Ruchi


    Full Text Available Abstract Background Traumatic perforation of the distal oesophagus due to blunt trauma is a very rare condition and is still associated with a significant morbidity and mortality. This is further exacerbated by delayed diagnosis and management as symptoms and signs are often masked by or ascribed to more common blunt thoracic injuries. Case report We present a case of a distal oesophageal perforation, secondary to a fall from a third storey window, which was masked by concomitant thoracic injuries and missed on both computed tomography imaging and laparotomy. The delay in his diagnosis significantly worsened the patient's recovery by allowing the development of an overwhelming chest sepsis that contributed to his death. Conclusion Early identification of an intrathoracic oesophageal perforation requires deliberate consideration and is essential to ensure a favorable outcome. Treatment should be individualised taking into account the nature of the oesophageal defect, time elapsed from injury and the patient's general condition.

  1. A Case of Concomitant Perforated Acute Cholecystitis and Pancreatitis

    Directory of Open Access Journals (Sweden)

    Marlon Perera


    Full Text Available Introduction. Concomitant cholecystitis and gallstone pancreatitis is an infrequent clinical encounter, reported sparsely in the literature. Concurrent acute cholecystitis and pancreatitis complicated by gall bladder perforation has not been reported before. Presentation of Case. We report a 39-year-old female presenting with concomitant cholecystitis and acute pancreatitis, complicated by gallbladder perforation. Discussion. There is much controversy surrounding the timing of cholecystectomy following gallstone pancreatitis, with the recent literature suggesting that “early” operation is safe. In the current case, gallbladder perforation altered the “routine” management of gallstone pancreatitis and posed as a management dilemma. Conclusion. Clinical judgement dictated timing of operative management and ultimately cholecystectomy was performed safely.

  3. Primary tubercular caecal perforation: a rare clinical entity

    Directory of Open Access Journals (Sweden)

    Moses Sonia


    Full Text Available Abstract Background Intestinal tuberculosis is a common problem in endemic areas, causing considerable morbidity and mortality. An isolated primary caecal perforation of tubercular origin is exceptionally uncommon. Case presentation We report the case of a 39 year old male who presented with features of perforation peritonitis, which on laparotomy revealed a caecal perforation with a dusky appendix. A standard right hemicolectomy with ileostomy and peritoneal toileting was done. Histopathology revealed multiple transmural caseating granulomas with Langerhans-type giant cells and acid-fast bacilli, consistent with tuberculosis, present only in the caecum. Conclusions We report this extremely rare presentation of primary caecal tuberculosis to sensitize the medical fraternity to its rare occurrence, which will be of paramount importance owing to the increasing incidence of tuberculosis all over the world, especially among the developing countries.

We enrolled 370 patients with traumatic TM perforations of different sizes. These patients were randomly assigned to control group and treatment group. In the treatment group, a sterile cotton patch with sea buckthorn oil was used to cover the TM perforations. In the control group, patients were treated with a sterile cotton patch. The healing rate and time were compared between the two groups. We found that the overall healing rate was significantly higher in the treatment group than in the control group. For middle and large TM perforations, sea buckthorn oil treatment led to a significant increase in the healing rate. At 2 months after injury, the duration of healing was, generally, shorter in the treatment group than in the control group (P<0.05. In conclusion, sea buckthorn oil patches are effective in treating middle and large TM perforations, which results in increased healing rates and decreased healing time.

  5. High-energy gas fracturing in cased and perforated wellbores

    Energy Technology Data Exchange (ETDEWEB)

    Cuderman, J.F.


    A propellant-based technology, High-Energy Gas Fracturing (HEGF), has been applied to fracturing through perforations in cased boreholes. HEGF is a tailored-pulse fracturing technique originally developed by Sandia National Laboratories for application in uncased, liquid-free gas wells in Appalachian Devonian shales. Because most oil and gas wells are liquid filled as well as cased and perforated, the potential impact of present research is significantly broader. A number of commercial tailored-pulse fracturing services, using a variety of explosives or propellants, are currently available. Present research provides valuable insight into phenomena that occur in those stimulations. The use of propellants that deflagrate or burn rather than detonate, as do high-order explosives, permits controlled buildup of pressure in the wellbore. The key to successful stimulation in cased and perforated wellbores is to control the pressure buildup of the combustion gases to maximize fracturing without destroying the casing. Eight experiments using cased and perforated wellbore were conducted in a tunnel complex at the Department of Energy's Nevada Test Site, which provides a realistic in situ stress environment (4 to 10 MPa (600 to 1500 psi)) and provides access for mineback to directly observe fracturing obtained. Primary variables in the experiments include propellant burn rate and amount of propellant used, presence or absence of liquid in the wellbore, in situ stress orientation, and perforation diameter, density, and phasing. In general, the presence of liquid in the borehole results in a much faster pressure risetime and a lower peak pressure for the same propellant charge. Fracture surfaces proceed outward along lines of perforations as determined by phasing, then gradually turn toward the hydraulic fracture direction. 8 refs., 23 figs., 3 tabs.

  6. Practical Considerations for Perforator Flap Thinning Procedures Revisited

    Directory of Open Access Journals (Sweden)

    Theddeus OH Prasetyono


    Full Text Available BackgroundA thin perforator flap is one of the best methods for covering defects. This study aimed to revisit and further test the rapidly advancing field of flap thinning techniques.MethodsWe performed two cadaveric studies to test the known flap thinning methods, and then applied these methods to a clinical series. In the first study, five cadavers were used to observe the anatomical relation of the perforator with the subdermal plexuses and the subcutaneous fat layer by injecting a colored latex solution. The second study was done on four cadavers independently from the first study. Last, a clinical series was performed on 15 patients.ResultsThe areolar fat lobules of 10 anterolateral thigh perforator (ALT, seven deep inferior epigastric artery perforator (DIEAP, and six thoracodorsal artery perforator (TAP flaps were dissected to reduce the flap thickness guided by the colored vascular pattern. On average, the ALT, DIEAP, and TAP flaps were reduced to 32.76%±9.76%, 37.01%±9.21%, and 35.42%±9.41%, respectively. In the second study, the areolar fat lobules were directly dissected in six ALT, six TAP, and four MSAP flaps, and an average reduction in flap thickness of 53.41%±5.64%, 52.30%±2.88%, and 47.87%±6.41%, respectively, was found. In the clinical series, 13 out of the 15 cases yielded satisfactory outcomes with an average thickness reduction of 37.91%±7.15%.ConclusionsThese multiple studies showed that the deep fat layer could be safely removed to obtain a thin yet viable perforator flap. This evidence suggests that the macroscopic flap thinning technique can achieve thin flaps. Surgeons should consider this technique before embracing the latest technique of supermicrosurgery.

  7. Perforating the atretic pulmonary valve with CTO hardware: Technical aspects. (United States)

    Patil, Nilkanth C; Saxena, Anita; Gupta, Saurabh K; Juneja, Rajnish; Mishra, Sundeep; Ramakrishnan, Sivasubramanian; Kothari, Shyam S


    To review the success and technical aspects of pulmonary valve (PV) perforation using chronic total occlusion (CTO) hardware in patients with pulmonary atresia and intact ventricular septum (PA-IVS). Interventional therapy is possible in selected patients with PA-IVS. Among the various interventional options available, radiofrequency and laser assisted perforation may be more successful, but require expertise and may be substantially costly. We describe the technique of mechanical catheter PV perforation using currently available coronary hardware meant for coronary CTO in nine cases with PA-IVS. After complete echocardiographic evaluation and informed parental consent was obtained, patients were electively intubated, mechanically ventilated, adequately heparinized and were placed on intravenous prostaglandin infusion. Basic steps involved were-localizing the atretic segment and accomplishing coaxial alignment of catheters using biplane fluoroscopy, crossing the atretic segment with the soft end of perforating guidewire, stabilizing the assembly and performing graded balloon dilatation with the balloon size never exceeding 130% of pulmonary annulus diameter. For crossing the atretic PV, a retrograde approach was used in one patient where the antegrade approach was not possible. The procedure was successful in 8/9 cases (89%). Valve opening was achieved in all eight patients with immediate fall in right ventricular (RV) systolic pressures. One neonate died following surgery after catheter induced RV perforation. All surviving cases were discharged from the hospital in good general condition with no evidence of heart failure and a room air oxygen saturation of >85%. No patient required an additional pulmonary irrigation procedure. With appropriate patient and hardware selection, PV perforation using readily available coronary hardware is feasible in PA-IVS. © 2014 Wiley Periodicals, Inc. © 2014 Wiley Periodicals, Inc.

    Christensen, P; Krogh, K; Perrouin-Verbe, B; Leder, D; Bazzocchi, G; Petersen Jakobsen, B; Emmanuel, A V


    Transanal irrigation is increasingly used against chronic constipation and fecal incontinence in selected patients. The aims were to estimate the incidence of irrigation-related bowel perforation in patients using the Peristeen Anal Irrigation(®) system, and to explore patient- and procedure-related factors associated with perforation. External independent expert audit on the complete set of global vigilance data related to Peristeen Anal Irrigation from 2005 to 2013. In total, 49 reports of bowel perforation had been recorded. Based on sales figures, this corresponds to an average risk of bowel perforation of 6 per million procedures. The latest two-year data indicate a risk of 2 per million procedures. In 29 out of 43 evaluable cases (67 %), perforation happened within the first 8 weeks since start of treatment. After 8 weeks, long-term use has an estimated risk of less than 2 per million procedures. Among patients with non-neurogenic bowel dysfunction, 11 out of 15 (73 %) had a history of pelvic organ surgery compared to 5 out of 26 (19 %) in neurogenic bowel dysfunction. In 11 of 46 (24 %) evaluable cases, burst of the rectal balloon was reported. Enema-induced perforation is a rare complication to transanal irrigation with Peristeen Anal Irrigation, which increases the benefit risk ratio in support of the further use of transanal irrigation. Increased risk is present during treatment initiation and in patients with prior pelvic organ surgery. Careful patient selection, patient evaluation and proper training of patients are critical to safe practice of this technique.

  9. Transmission conditions for the Helmholtzequation in perforated domains


    Dörlemann, Christina; Heida, Martin; Schweizer, Ben


    We study the Helmholtz equation in a perforated domain . The domain Ωε. The domain Ωε is obtained from an open set Ω⊂ℝ³ by removing small obstacles of typical size ε > 0, the obstacles are located along a 2-dimensional manifold Γ0 ⊂Ω, We derive effective transmission conditions across Γ0 that characterize solutions in the limit ε→0O. We obtain that, to leading order O(ε0)=O(1), the perforation is invisible. On the other hand, at order O(ε1)=O(ε), inhomogeneous jump conditions...

    Preoperative imaging using a range of imaging modalities has become increasingly popular for preoperative planning in plastic surgery, in particular in perforator flap surgery. Modalities in this role include ultrasound (US), magnetic resonance angiography (MRA), and computed tomographic angiography (CTA). The evidence for the use of these techniques has been reported in only a handful of studies. In this paper we conducted a non-systematic review of the literature to establish the role for each of these modalities. The role of state-of-the-art vascular imaging as an application in perforator flap surgery is thus offered.

    We present a prospective and protocolizeted study of 98 patients over 65 years, underwent emergency surgery for perforated acute abdomen in the Hospital Nacional de Clínicas during the period from April/2007 to April/2013. The purpose was to determine the morbidity and mortality of this entity in the elderly. Mainly affected were women between 65 and 75 years. The leading cause of intervention was the colonic involvement, in its entirety. Septic complications and renal failure are the disorders that prevailed. Practical application of Mannheim peritonitis index. The perforated acute abdomen is a picture with a high rate of mortality in the elderly.

  12. Conservative management of esophageal perforation after a fall. (United States)

    Delos Reyes, Arthur P; Clancy, Christopher; Lach, Joseph; Olorunto, William A; Williams, Mallory


    Esophageal perforation in the setting of blunt trauma is rare, and diagnosis can be difficult due to atypical signs and symptoms accompanied by distracting injury. We present a case of esophageal perforation resulting from a fall from height. Unexplained air in the soft tissues planes posterior to the esophagus as well as subcutaneous emphysema in the absence of a pneumothorax on CT aroused clinical suspicions of an injury to the aerodigestive tract. The patient suffered multiple injuries including bilateral first rib fractures, C6 lamina fractures, C4-C6 spinous process fractures, a C7 right transverse process fracture with associated ligamentous injury and cord contusion, multiple comminuted nasal bone fractures, and a right verterbral artery dissection. Esophageal injury was localized using a gastrograffin esophagram to the cervical esophagus and was most likely secondary to cervical spine fractures. Because there were no clinical signs of sepsis and the esophagram demonstrated a contained rupture, the patient was thought to be a good candidate for a trial of conservative management consisting of broad spectrum intravenous antibiotics, oral care with chlorhexadine gluconate, NPO, and total parenteral nutrition. No cervical spine fixation or procedure was performed during this trial of conservative management. The patient was received another gastrograffin esophagram on hospital day 14 and demonstrated no evidence of contrast extravasation. Early diagnosis and control of the infectious source are the cornerstones to successful management of esophageal perforation from all etiologies. Traditionally, esophageal perforation relied on a high index of clinical suspicion for early diagnosis, but the use of CT scan for has proved to be highly effective in diagnosing esophageal perforation especially in patients with atypical presentations. While aggressive surgical infection control is paramount in the majority of esophageal perforations, a select subset of patients can

    Ripolles, T.; Concepcion, L.; Martinez-Perez, M.J.; Morote, V. [Dept. of Radiology, Dr. Peset Hospital, Valencia (Spain)


    We describe four patients in whom ultrasound (US) and/or computed tomography (CT) demonstrated a thickened appendix, secondarily enlarged due to perforated sigmoid diverticulitis (n = 2) or carcinoma (n = 2). The underlying pathology was correctly recognized in all cases. Secondary thickening of the appendix due to perforated sigmoid disease provides a potential pitfall mainly on US and may lead to an incorrect diagnosis and thus to unnecessary surgery or a wrong surgical intervention. Although US alone is enough to diagnose periappendicitis and sigmoid disease, combined use of US and CT may improve assessment of its origin and extension. (orig.) With 4 figs., 19 refs.

    In the majority of surgical departments in Denmark, the postoperative treatment for acute perforated appendicitis comprises three days of intravenous antibiotics. Recently, it has been proposed that such antibiotic regimen should be replaced by orally administered antibiotics. The aim of this paper...... was to give an overview of studies on acute perforated appendicitis with postoperative oral antibiotics. Five studies were found in a database search covering the 1966-2009 period. There is no evidence to support a conversion of the postoperative antibiotic regimen from intravenous to oral administration...

  16. An Improved Model for Air Damping of Perforated Structures (United States)

    Lu, Cunhao; Li, Pu


    the prediction of air damping of micromachined mechanical resonant structures is significant in the design of high quality factor devices. In rarefied air, based on Bao’s molecule model, Li gives an analytical model for air damping of perforated structures. By studying the action of molecules going through holes and reflected by the fixed plate, this paper gives a probability of molecules through holes going into the gap between the moving plate and the fixed one. Comparison with Li’s model, the new model can play a better performance of air damping for perforated structures, at a wide range of size of holes.

  17. Experimental Method for Determining Forces at Bending of Perforated Plates (United States)

    Pascu, Adrian; Oleksik, Mihaela; Avrigean, Eugen


    This paper describes the method of calculating the forces which appear at the bending of perforated plates with holes of different shapes and placed in different patterns, by means of a dynamometric table which uses resistive tensometric transducers (strain gauges). It also describes an instrument for the recording of data from the dynamometric table, a tool created with the aid of the "TestPoint" software which, beneath the data recording, ensures the filtering and statistic processing of data. The obtained results are displayed in comparative graphs for six types of perforated plates, as well as for an unperforated plate.

    Duplication cysts of the gastrointestinal tract are rare congenital abnormalities. Ectopic gastric mucosa, which can be found in duplications, may cause peptic ulceration, gastrointestinal bleeding or perforation. We report a 1-year-old boy with a perforated ileal duplication cyst with haemorrhagic pseudocyst formation caused by peptic ulceration of the duplication cyst. It presented a snowman-like appearance consisting of a small, thick-walled, true enteric cyst and a large, thin-walled haemorrhagic pseudocyst on US and CT. It is an unusual manifestation of a duplication cyst, which has not been reported in the English language literature. (orig.)

  19. Case Report: A Neocystostomy Perforation Presenting as a Gallstone

    R. Kalra


    Full Text Available An 83-year-old man, with a surgical history of radical cystectomy with simultaneous construction of a neobladder 13 years ago, presented clinically and radiologically as acute cholecystitis. Upon emergent exploratory laparotomy for his acute deterioration, a perforated neobladder was identified with its spilled stones in the gallbladder fossa, mimicking acute cholecystitis. This is the first case report of this presentation. Neobladder perforations should be considered in any patient who has undergone orthotopic bladder substitution, no matter how long it has been since the original reconstruction.

  20. Isolated perforation of a duodenal diverticulum following blunt abdominal trauma

    Directory of Open Access Journals (Sweden)

    Metcalfe Matthew


    Full Text Available Only 10% of duodenal diverticula are symptomatic. We present the case of a man who fell from a height of 6 ft, landing on his abdomen and presenting 4 h later with severe back pain and a rigid abdomen. At laparotomy, a perforated retroperitoneal duodenal diverticulum was found and repaired with an omental patch. No other injury was noted. Not only is this perforation unusual, but the absence of other injuries sustained during this minor blunt trauma makes this case unique. This case highlights the need for a high index of suspicion when managing patients with back or abdominal pain following minor trauma.

  1. Successes rate of endoscopic dacryocystorhinostomy at KMC. (United States)

    Shrestha, S; Kafle, P K; Pokhrel, S; Maharjan, M; Toran, K C


    Nasolacrimal duct obstruction is a common problem which can be corrected by dacryocystorhinostomy (DCR). The gold standard treatment for this is DCR operation through an external approach. Development of endoscopic sinus surgery and endoscopic DCR performed through intranasal route is a major recent development in this field. The aim of this study is to find out the success rate of endoscopic dacryocystorhinostomy without silicon stent intubation within the period of six month following surgery. A prospective study was done on 26 patients with obstruction of the nasolacrimal duct referred from eye out-patient department to ENT OPD during one year period from 2008 to 2009. All the cases had undergone endoscopic DCR operation which was regularly followed up for a period of six months. Postoperative patency of ostium was checked by sac syringing and endoscopic visualisation of ostium in the nasal cavity. The success of surgery was categorised as: complete cure, partial cure and no improvement depending upon symptomatic relief and clinical examination such as sac syringing and endoscopic examination following surgery. In six months' follow-up, 22 (84.5%) out of 26 patients had achieved the complete cure and 4 patients (15.5%) continued to have persistent epiphora. Endoscopic DCR is a beneficial procedure for nasolacrimal duct obstruction with no external scar on face and less bleeding. The success rate is as good as external DCR.

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

    Wright, Andrew; Chang, Andrew; Bedi, Aarti Oza; Wamsteker, Erik-Jan; Elta, Grace; Kwon, Richard S; Carrott, Phillip; Elmunzer, B Joseph; Law, Ryan


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

  3. Stent migration following endoscopic suture fixation of esophageal self-expandable metal stents: a systematic review and meta-analysis. (United States)

    Law, Ryan; Prabhu, Anoop; Fujii-Lau, Larissa; Shannon, Carol; Singh, Siddharth


    Covered self-expandable metal stents (SEMS) are utilized for the management of benign and malignant esophageal conditions; however, covered SEMS are prone to migration. Endoscopic suture fixation may mitigate the migration risk of covered esophageal SEMS. Hence, we conducted a systematic review and meta-analysis to evaluate the effectiveness and safety of endoscopic suture fixation for covered esophageal SEMS. Following PRISMA guidelines, we performed a systematic review from 2011 to 2016 to identify studies (case control/case series) reporting the technical success and migration rate of covered esophageal SEMS following endoscopic suture fixation. We searched multiple electronic databases and conference proceedings. We calculated pooled rates (and 95% confidence intervals [CI]) of technical success and stent migration using a random effects model. We identified 14 studies (212 patients) describing covered esophageal SEMS placement with endoscopic suture fixation. When reported, SEMS indications included leak/fistula (n = 75), stricture (n = 65), perforation (n = 10), and achalasia (n = 4). The pooled technical success rate was 96.7% (95% CI 92.3-98.6), without heterogeneity (I 2  = 0%). We identified 29 SEMS migrations at rate of 15.9% (95% CI 11.4-21.6), without heterogeneity (I 2  = 0%). Publication bias was observed, and using the trim-and-fill method, a more conservative estimate for stent migration was 17.0%. Suture-related adverse events were estimated to occur in 3.7% (95% CI 1.6-8.2) of cases. Endoscopic suture fixation of covered esophageal SEMS appears to reduce stent migration when compared to published rates of non-anchored SEMS. However, SEMS migration still occurs in approximately 1 out of 6 cases despite excellent immediate technical success and low risk of suture-related adverse events.

  4. Minimally invasive surgery for resection of duodenal carcinoid tumors: endoscopic full-thickness resection under laparoscopic observation. (United States)

    Carcinoid tumors of the duodenum are rare, and the most effective treatment for duodenal carcinoid tumors remains debatable. Because carcinoid tumors of the gastrointestinal tract tend to spread to the submucosal layer even during the early stages of the disease, the possibility of tumor seeding in the vertical margin of the tumor cannot be eliminated by conventional endoscopic mucosal resection (EMR). In addition, because the duodenal wall is thinner than the gastric wall, EMR performed for duodenal lesions may be associated with a high risk of accidental perforation. In this article, we introduce a minimally invasive endoscopic full-thickness resection technique after laparoscopic repair for the local resection of duodenal carcinoid tumors. Under general anesthesia, after the duodenum was mobilized laparoscopically, the duodenal serosa at the site of the lesion was suctioned under laparoscopic observation, and full-thickness resection of the duodenum was performed using a cap-fitted endoscope, i.e., EMR-c, without injecting hypertonic saline-epinephrine. The sample was retrieved endoscopically after resection. After confirming that the full-thickness resection of the duodenal wall with enough surgical margins was achieved and that there was no active bleeding, the wound was sutured by the laparoscopic hand-suturing technique. We have performed this surgical procedure in two cases of duodenal carcinoid tumor. The mean operation time was 116 +/- 14 minutes, and the estimated blood loss was 2.5 +/- 0.5 ml. The postoperative courses were uneventful in both cases. The technique of endoscopic full-thickness resection of gastrointestinal tract under laparoscopic observation is a safe, simple, and can be radical surgical procedure for a small duodenal carcinoid tumor. This surgical procedure may be applicable in the case of other gastrointestinal tumors.

    Full Text Available Environmental modifications caused by low tunnels made of perforated transparent polyethylene were determineted in an area alocated at the Federal University of Santa Maria, RS. The perforation densities were 100, 200, 300 and 400 perforations per square meter, corresponding respectively to 0.78% (T1, 1.57% CT2, 2.35% (T3 and 3.14% (T4 of area perforated. The results indicated that perforation density did not significantly affected solar energy availability. As perforation density increased there was a decrease on the average diurnal air temperature which demonstrated the viability of ventilating low tunnels with perforated plastic. It was also observed that inside the perforated tunnels the averages values for soil, air minimun and diurnal temperatures and air relative humidity were higher than on the external environment.

  7. Endoscopic retrograde cholangiopancreatography for primary sclerosing cholangitis. (United States)

    Thosani, Nirav; Banerjee, Subhas


    Although there are no randomized, controlled trials evaluating the efficacy of endoscopic retrograde cholangiography (ERC) in primary sclerosing cholangitis (PSC) patients, substantial indirect evidence supports the effectiveness of ERC in symptomatic PSC patients with a dominant stricture. Currently, cumulative evidence supports the role of ERC with endoscopic dilation with or without additional short-term stent placement for symptomatic PSC patients with a dominant stricture. Differentiating benign dominant strictures from cholangiocarcinoma (CCA) remains difficult; however, newer endoscopic techniques and advanced cytologic techniques are likely to improve sensitivity for the diagnosis of CCA over that achieved by traditional cytology brushing alone.

    Full Text Available While percutaneous endoscopic gastrostomy (PEG is a well-known approach for achieving enteral feeding, direct percutaneous endoscopic jejunostomy (DPEJ is a technique that allows endoscopic placement of percutaneous/transabdominal feeding tube directly into the jejunum. It offers a non-surgical alternative for postpyloric enteral feeding for long-term nutritional support when gastric feeding is not technically possible or is inappriopriate. Conventionally DPEJ is done with pediatric colonoscope or small bowel enteroscope. Here, we report a case where DPEJ was accomplished with gastroscope.

    Full Text Available To evaluate the usefulness of ultrasonography, endoscopic retrieval, and the outcome of patients with diabetes mellitus presenting with ureteric obstruction caused by necrosed renal papillae. Material And Methods: Eleven seriously ill patients with diabetes mellitus, admitted into medical wards, were found to have ureteric obstruction complicated by urinary infection. The diagnosis was made by ultrasonography alone. Prompt relief followed endoscopic extraction of the offending necrosed papillae. Results: Ten patients improved dramatically. One patient died from septicemia. Conclusions: Ultrasonography appears to be a useful diagnostic method to diagnose ureteric obstruction. It is cheap, fast, and extremely reliable. Endoscopic extraction of the obstructing papilla offers the best chance for successful outcome.

  10. Comparative study of software techniques for 3D mapping of perforators in deep inferior epigastric artery perforator flap planning (United States)

    Hunter-Smith, David J.; Rozen, Warren Matthew


    Background Computed tomographic (CT) angiography (CTA) is widely considered the gold standard imaging modality for preoperative planning autologous breast reconstruction with deep inferior epigastric artery (DIEA) perforator (DIEP) flap. Improved anatomical understanding from CTA has translated to enhanced clinical outcomes. To achieve this, the use of appropriate CT hardware and software is vital. Various CT scanners and contrast materials have been demonstrated to consistently produce adequate scan data. However, the availability of affordable and easily accessible imaging software capable of generating 3D volume-rendered perforator images to clinically useful quality has been lacking. Osirix (Pixmeo, Geneva, Switzerland) is a free, readily available medical image processing software that shows promise. We have previously demonstrated in a case report the usefulness of Osirix in localizing perforators and their course. Methods In the current case series of 50 consecutive CTA scans, we compare the accuracy of Osirix to a commonly used proprietary 3D imaging software, Siemens Syngo InSpace 4D (Siemens, Erlangen, Germany), in identifying perforator number and location. Moreover, we compared both programs to intraoperative findings. Results We report a high rate of concordance with Osirix and Siemens Syngo InSpace 4D (99.6%). Both programs correlated closely with operative findings (92.2%). Most of the discrepancies were found in the lateral row perforators (90%). Conclusions In the current study, we report the accuracy of Osirix that is comparable to Siemens Syngo InSpace 4D, a proprietary software, in mapping perforators. However, it provides an added advantage of being free, easy-to-use, portable, and potentially a superior quality of 3D reconstructed image. PMID:27047778

  11. Clinical endoscopic management and outcome of post-endoscopic sphincterotomy bleeding.

    Wei-Chen Lin

    Full Text Available Post-endoscopic sphincterotomy bleeding is a common complication of biliary sphincterotomy, and the incidence varies from 1% to 48%. It can be challenging to localize the bleeder or to administer various interventions through a side-viewing endoscope. This study aimed to evaluate the risk factors of post-endoscopic sphincterotomy bleeding and the outcome of endoscopic intervention therapies. We retrospectively reviewed the records of 513 patients who underwent biliary sphincterotomy in Mackay Memorial Hospital between 2011 and 2016. The blood biochemistry, comorbidities, indication for sphincterotomy, severity of bleeding, endoscopic features of bleeder, and type of endoscopic therapy were analyzed. Post-endoscopic sphincterotomy bleeding occurred in 65 (12.6% patients. Forty-five patients had immediate bleeding and 20 patients had delayed bleeding. The multivariate analysis of risk factors associated with post-endoscopic sphincterotomy bleeding were liver cirrhosis (P = 0.029, end-stage renal disease (P = 0.038, previous antiplatelet drug use (P<0.001, and duodenal ulcer (P = 0.023. The complications of pancreatitis and cholangitis were higher in the bleeding group, with statistical significance. Delayed bleeding occurred within 1 to 7 days (mean, 2.5 days, and 60% (12/20 of the patients received endoscopic evaluation. In the delayed bleeding group, the successful hemostasis rate was 71.4% (5/7, and 65% (13/20 of the patients had ceased bleeding without endoscopic hemostasis therapy. Comparison of different therapeutic modalities showed that cholangitis was higher in patients who received epinephrine spray (P = 0.042 and pancreatitis was higher in patients who received epinephrine injection and electrocoagulation (P = 0.041 and P = 0.039 respectively. Clinically, post-endoscopic sphincterotomy bleeding and further endoscopic hemostasis therapy increase the complication rate of pancreatitis and cholangitis. Realizing the effectiveness of each

  12. Analysis of opto-thermal interaction of porcine stomach tissue with 808-nm laser for endoscopic submucosal dissection

    Directory of Open Access Journals (Sweden)

    Seongjun Kim


    Full Text Available In endoscopic submucosal dissection (ESD, the narrow gastrointestinal space can cause difficulty in surgical interventions. Tissue ablation apparatuses with high-power CO2 lasers or Nd:YAG lasers have been developed to facilitate endoscopic surgical procedures. We studied the interaction of 808-nm laser light with a porcine stomach tissue, with the aim of developing a therapeutic medical device that can remove lesions at the gastrointestinal wall by irradiating a near-infrared laser light incorporated in an endoscopic system. The perforation depths at the porcine fillet and the stomach tissues linearly increased in the range of 2–8 mm in proportion to the laser energy density of 63.7–382 kJ/cm2. Despite the distinct structural and compositional difference, the variation of the perforation depth between the stomach and the fillet was not found at 808-nm wavelength in our measurement. We further studied the laser–tissue interaction by changing the concentration of the methyl blue solution used conventionally as a submucosal fluidic cushion (SFC in ESD procedures. The temperature of the mucosal layer increased more rapidly at higher concentration of the methyl blue solution, because of enhanced light absorption at the SFC layer. The insertion of the SFC would protect the muscle layer from thermal damage. We confirmed that more effective laser treatment should be enabled by tuning the opto-thermal properties of the SFC. This study can contribute to the optimization of the driving parameters for laser incision techniques as an alternative to conventional surgical interventions.

  13. The Helminths Causing Surgical or Endoscopic Abdominal Intervention: A Review Article

    Directory of Open Access Journals (Sweden)

    Erdal UYSAL


    Full Text Available Background: Helminths sometimes require surgical or endoscopic intervention. Helminths may cause acute abdomen, mechanical intestinal obstruction, gastrointestinal hemorrhage, perforation, hepatitis, pancreatitis, and appendicitis. This study aimed to determine the surgical diseases that helminths cause and to gather, analyze the case reports, case series and original articles about this topic in literature.Methods: This study was designed as a retrospective observational study. In order to determine the studies published in literature, the search limits in PubMed database were set to 1 Jan 1957 and 31 Mar 2016 (59 yr, and the articles regarding Helminth-Surgery-Endoscopy were taken into examination. Among 521 articles scanned, 337 specific ones were involved in this study.Results: The most common surgical pathology was found to be in Ascaris lumbricoides group. Enterobius vermicularis was found to be the parasite that caused highest amount of acute appendicitis. Anisakiasis was observed to seem mainly because of abdominal pain and mechanical intestinal obstruction. Strongyloides stercoraries causes duodenal pathologies such as duodenal obstruction and duodenitis. Taenia saginata comes into prominence with appendicitis and gastrointestinal perforations. Fasciola hepatica exhibits biliary tract involvement and causes common bile duct obstruction. Hookworms were observed to arise along with gastrointestinal hemorrhage and anemia. Trichuris trichiuria draws attention with gastrointestinal hemorrhage, mechanical intestinal obstruction.Conclusion: Helminths may lead to life-threatening clinic conditions such as acute abdomen, gastrointestinal perforation, intestinal obstruction, and hemorrhages. There is a relationship between surgery and helminths. It is very important for surgeons to consider and remember helminths in differential diagnoses during their daily routines.

  5. Vibroacoustic properties of thin micro-perforated panel absorbers. (United States)

    Bravo, Teresa; Maury, Cédric; Pinhède, Cédric


    This paper presents theoretical and experimental results on the influence of panel vibrations on the sound absorption properties of thin micro-perforated panel absorbers (MPPA). Measurements show that the absorption performance of thin MPPAs generates extra absorption peaks or dips that cannot be understood assuming a rigid MPPA. A theoretical model is established that accounts for structural-acoustic interaction between the micro-perforated panel and the backing cavity, assuming uniform conservative boundary conditions for the panel and separable coordinates for the cavity cross-section. This model is verified experimentally against impedance tube measurements and laser vibrometric scans of the cavity-backed panel response. It is shown analytically and experimentally that the air-frame relative velocity is a key factor that alters the input acoustic impedance of thin MPPAs. Coupled mode analysis reveals that the two first resonances of an elastic MPPA are either panel-cavity, hole-cavity, or panel-controlled resonances, depending on whether the effective air mass of the perforations is greater or lower than the first panel modal mass. A critical value of the perforation ratio is found through which the MPPA resonances experience a frequency "jump" and that determines two absorption mechanisms operating out of the transitional region.

  13. Spontaneous Uterine Perforation of Pyometra Presenting as Acute Abdomen

    Directory of Open Access Journals (Sweden)

    Toshihiro Kitai


    Full Text Available Pyometra is the accumulation of pus in the uterine cavity, and spontaneous perforation of pyometra resulting in generalized diffuse peritonitis is extremely uncommon. We report a rare case of diffuse peritonitis caused by spontaneous perforation of pyometra. A 66-year-old postmenopausal woman with diffuse abdominal pain and vomiting was admitted to our institution. She had a history of mixed connective-tissue disease and had been taking steroids for 20 years. Under a diagnosis of generalized peritonitis secondary to perforation of the gastrointestinal tract or uterus, supravaginal hysterectomy and bilateral salpingo-oophorectomy were performed. Unfortunately, wound dehiscence and infection occurred during the postoperative course, which were exacerbated by her immunocompromised state. Despite intensive care and a course of antibiotics, the patient died of multiple organ failure resulting from sepsis on the 36th postoperative day. Although correct diagnosis, early intervention, and proper treatment can reduce morbidity and mortality of spontaneous perforation of pyometra, if severe infection occurs, this disease can be life threatening for immunocompromised hosts.

  4. [Conservative management of esophageal perforation after pneumatic dilatation for achalasia]. (United States)

    Scatton, Olivier; Gaudric, Marianne; Massault, Pierre-Philippe; Chaussade, Stanislas; Houssin, Didier; Dousset, Bertrand


    To assess the results and indications of conservative management of esophageal perforation following pneumatic dilatation for achalasia. Thirteen esophageal perforations complicating 524 dilatations in 412 patients (3%) were diagnosed by esophagogram. Medical treatment consisted of nasogastric succion, antibiotics and pleural drainage, if necessary. Conservative surgical treatment included left thoracophrenotomy, perforation closure, controlateral myotomy and anterior fundoplication. Surgical decision was based upon clinical and radiological parameters. Functional outcome was assessed by the means of the Eckardt's grading score. Six patients were successfully managed by medical treatment. Seven patients underwent conservative surgery, three of whom after failure of medical treatment. The presence of a pneumomediastinum at initial presentation led to immediate (n=2) or delayed (n=2) surgery in all instances. No patients died. In the surgical group, morbidity consisted of one wound infection, one pleural effusion and one venous thrombosis. One severe chest infection occurred in the medical group. Oral feeding was reintroduced after a median of 10 and 11 days in the surgical and medical groups, respectively. Functional results were satisfactory and similar in both groups. Conservative medical or surgical management of oesophageal perforation following pneumatic dilatation is safe, if the diagnosis is done early. Pneumomediastinum at initial presentation seems to predict failure of conservative medical treatment.

  6. Scour around a perforated disk modeling a marine hydrokinetic device (United States)

    Beninati, M. L.; Soliani, G.; Zhou, C. C.; Krane, M.; Fontaine, A.


    A study was conducted to investigate the behavior of scour hole dimensions and scour rates around a bottom-mounted cylindrical support structure of a perforated disk. The experiments focus on collecting temporal variations of scour depth around the support structure of the perforated disk for two scour regimes: transitional (ReD = 8500 and 9400) and live-bed (ReD = 10200). A perforated disk is used to approximate the drag of a submerged, horizontal axis, marine hydrokinetic (MHK) turbine. The goal is to compare the scour behavior around a perforated disk to that of a marine hydrokinetic (MHK) device. This study is motivated by the need to predict the environmental effect of MHK devices on an erodible bed. Testing is conducted in the small-scale hydraulic flume facility (1.2 m wide, 0.38 m deep, and 9.75 m long) at Bucknell University. The base of the support structure is marked incrementally to allow for time based observations of changes in scour depth. Bed form topologies are then acquired after a three hour time interval using a 2D sediment bed profiler. Experimental results show that scour rate is dependent on flow speed. Additionally, an increase in scour hole size occurs as the scour conditions are varied from transitional to live-bed.
