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

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

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

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

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

    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.

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

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

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

  10. Endoscopic treatment of vesicoureteral reflux: Current status

    2009-01-01

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

  11. Update on the endoscopic treatments for achalasia.

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

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

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

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

    2013-04-01

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

    2014-09-28

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

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

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

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

The patients were divided into two groups: in 2000-2004 years without endoscopic methods, in 2004-2008 years using the endoscopic methods in the diagnostics and treatment. Considerably decreased operative activity and death rate was established in cases of treatment with endoscopic methods.

  8. Treatment Strategy after Incomplete Endoscopic Resection of Early Gastric Cancer

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

    Clinical symptoms are the most important factors used by physicians to evaluate the severity and extent of ulcerative colitis (UC). In this context, colonoscopy is also a useful diagnostic tool. We have recently developed an endoscopic activity index (EAI) to assess the severity of UC. Here, we assess the correlations among the EAI, other endoscopic indices, and clinical scores. The usefulness of the EAI for choosing treatment options, such as intravenous corticosteroid or cyclosporine A (CsA), in severe UC patients was also evaluated. Clinical symptoms and endoscopic finding were evaluated in 396 patients with UC (454 colonoscopies). The EAI was scored using the following six items: ulcer size, ulcer depth, redness, bleeding, edema, and mucus exudates. The patients were also scored using Matts' grade, Rachmilewitz's endoscopic index, and the Lichtiger index. Our results showed that (1) the EAI scores were closely correlated with those of the Lichtiger index, Matts' grade, and Rachmilewitz's endoscopic index; (2) the EAI scores significantly decreased in patients who responded to treatment, while Matts' grade did not change in some responders treated with intravenous CsA and steroid; (3) patients with a higher EAI (14-16) tended to be refractory to corticosteroid therapy (responders 19%) compared to CsA (77%), while steroid treatment was effective in 58% of patients with EAI scores of 11-13. The EAI is equivalent to other endoscopic indices and relatively more useful in choosing a treatment for patients with severe UC.

    Full Text Available Severe injuries of biliary or pancreatic ducts are associated with significant morbidity and mortality. Severe bile duct injuries such as major biliary leaks, complete transection, or complete occlusion of bile ducts can be grouped under the term complex bile duct injuries (CBDI. In the spectrum of pancreatic duct injuries, disconnected pancreatic duct syndrome (DPDS represents the most severe form and most often occurs after a severe episode of acute pancreatitis. Treatment of these complex injuries is quite challenging and for many years surgical management has been considered the treatment of choice. However, in the past few years, some studies have reported the successful management of CBDI or DPDS using endoscopic procedures alone or in combination with a percutaneous approach. In this review, we detail the endoscopic or combined endoscopic/percutaneous treatment possibilities for CBDI and DPDS.

    Patients with symptomatic cholelithiasis and suspected choledocolithiasis are a frequent clinical problem and there are different strategies for their treatment. This study evaluated the efficacy of a single cholecystocholedocolithiasis treatment by endoscopic papillotamy during cholecystectomy. Thirty-four patients 30 female and 4 male; average age 40.1 years, range 14 to 78) underwent cholecystectomy and endoscopic papillotomy Intra-operative transcystic cholangiography (IOC) confirmed choledocholithiasis or obstruction of the passage of the contrast medium to the duodenum. Through a hydrophilic guide passed through the cystic, a papillotomy was inserted endoscopically and papillotomy and removal if calculi with canastilla were carried out, as well as transcystic irrigation. choledocholithiasis was found in 32 patients (94%) and obstruction of the passage of the contrast medium in 2 (6%). Papillectomy was possible in all the cases and calculi were successfully removed in 28 patients (87.5%). Three patients required additional endoscopic procedures for the extraction if the calculi. One patient underwent open surgery Two patients had complications relating to the papillotomy 5.8%) with no mortality/morbidity. The average stay in hospital was 2.8 day and follow-up at 38 day. The combined endoscopic and surgical technique is useful in the treatment of patients with choledocholithasis

    Recurrent acute pancreatitis (RAP) is a challenging condition that can lead to chronic pancreatitis and long-term morbidity. Etiology-based treatment can potentially have an impact on the natural history of RAP and its progression to chronic pancreatitis. In cases of divisum-associated RAP and idiopathic RAP, several studies have been performed to evaluate the efficacy of endoscopic therapy in alleviation of symptoms and frequency of AP events. This review discusses the literature available on these topic as well as touching on the role of endoscopic therapy in smoldering acute pancreatitis. Published by Elsevier Inc.

    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.

    Full Text Available Ralf Eberhardt,1,2 Daniela Gompelmann,1,2 Felix JF Herth,1,2 Maren Schuhmann1 1Pneumology and Critical Care Medicine, Thoraxklinik at the University of Heidelberg, 2Translational Lung Research Center, Member of the German Center for Lung Research, Heidelberg, Germany Abstract: As well as lung volume reduction surgery, different minimally invasive endoscopic techniques are available to achieve lung volume reduction in patients with severe emphysema and significant hyperinflation. Lung function parameters and comorbidities of the patient, as well as the extent and distribution of the emphysema are factors to be considered when choosing the patient and the intervention. Endoscopic bronchial valve placement with complete occlusion of one lobe in patients with heterogeneous emphysema is the preferred technique because of its reversibility. The presence of high interlobar collateral ventilation will hinder successful treatment; therefore, endoscopic coil placement, polymeric lung volume reduction, or bronchoscopic thermal vapor ablation as well as lung volume reduction surgery can be used for treating patients with incomplete fissures. The effect of endoscopic lung volume reduction in patients with a homogeneous distribution of emphysema is still unclear and this subgroup should be treated only in clinical trials. Precise patient selection is necessary for interventions and to improve the outcome and reduce the risk and possible complications. Therefore, the patients should be discussed in a multidisciplinary approach prior to determining the most appropriate treatment for lung volume reduction.

    Bariatric endoscopic techniques are minimally invasive and induce gastric volume reduction to treat obesity. Aim : To evaluate endoscopic sleeve gastroplasty (Apollo method) using a suturing method directed at the greater curvature, as well as the perioperative care, two year safety and weight loss. Prospective single-center study over 154 patients (108 females) using the endoscopic sleeve gastroplasty procedure under general anesthesia with overnight inpatient observation. Of the154 initial patients, 143 were available for 1-month of follow-up, 133 for 6-month, 64 for 12-month and 28 completed the 24 month assessment. Follow-up was carried out by a multidisciplinary team (nutritionist and psychologist). Outcomes evaluated were: change in BMI; change in body weight (TBWL); % of loss of initial body weight (%TBWL); % of excess body weight loss (%EWL) (segregated in > or 25% %EWL. There were no mayor adverse events intraprocedure or during the 24 months of follow-up . Endoscopic sleeve gastroplasty with regular monitoring by a multidisciplinary team can be considered an effective, safe and well tolerated procedure for obesity treatment, at least for two years of follow-up.

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

    Full Text Available Eosinophilic esophagitis (EE is a motility disorder of the esophagus that typically presents with dysphagia. The objective of the present study was to explore patient characteristics, clinical and endoscopic features, and response to treatment of patients with EE. Patients were selected retrospectively based on a review of biopsy results from previous endoscopies performed between 2004 and 2008. A total of 54 patients (41 men and 13 women with biopsy-proven EE were included in the study. Further information regarding the patients’ clinical and endoscopic features, and response to treatment were obtained through chart reviews and patient telephone interviews. The mean age of the patients at symptom onset was 30 years. All patients complained of dysphagia, 81% had a history of bolus obstruction, 43% had a history of asthma and 70% had a history of environmental allergies. Thirty-three per cent had a family history of asthma, while 52% had a family history of food or seasonal allergies. The most common endoscopic findings were rings and/or corrugations, which were found in 63% of patients. Swallowed fluticasone therapy resulted in symptom resolution in 74% of patients; however, 79% of these patients relapsed after discontinuing fluticasone therapy and required repeat treatments. Esophageal dilation was complication free and resulted in improvement in 80% of patients. However, 83% of those reporting improvement relapsed within one year. The clinical and endoscopic findings were similar to those found in the literature, with most patients requiring ongoing, repeated therapies. Further studies are needed to assess the safety and efficacy of treatment modalities ideally suited to patients with EE.

    2017-01-01

    Esophageal cancer is one of the leading causes of cancer-related death and is associated with high morbidity and mortality. It carries a poor prognosis as more than half of patients present with advanced and unresectable disease. One contributing factor is the increased risk of lymph node metastases at early stages of disease. As such, it is essential to detect squamous cell neoplasia (SCN) at an early stage. In order to risk stratify lesions, endoscopists must be able to perform image enhanced endoscopy including magnification and Lugol’s chromoendoscopy. The assessment of both the horizontal extent and depth of any lesion is also of utmost importance prior to treatment. Endoscopic mucosal resection and submucosal dissection remain the standard of care with literature supportive their respective use. Radiofrequency ablation and other endoscopic treatments are currently available although should not be considered first line at this time. Our objective is to review the current options for the endoscopic diagnosis and treatment of esophageal SCN. PMID:28979708

    Few effective therapeutic tools are currently available to fight the increasing prevalence of obesity and its associated comorbidities. Bariatric surgery is the only treatment with proven long-term effectiveness, but is associated to a high surgical risk and significant economic costs because of its technical complexity and the characteristics of patients. This is leading to development of new endoscopic procedures with less clinical risks and economic costs, while maintaining the benefits in terms of morbidity and mortality, which could even serve as a bridging element before surgery in cases where this is unavoidable, allowing for preoperative weight loss and control of comorbidities in order to improve anesthetic risks and possible complications. The purpose of this review was to analyze the most relevant and promising endoscopic techniques currently available. Copyright © 2013 SEEN. Published by Elsevier Espana. All rights reserved.

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

    Per oral endoscopic myotomy (POEM) represents the culmination of natural orifice transluminal endoscopic surgery (NOTES) research, and its most successful application to date. Over a thousand POEMs have been performed globally with remarkable results in terms of clinical efficacy and safety. We examine the most recent literature concerning POEM since the last two comprehensive analyses [Natural Orifice Surgery Consortium for Assessment and Research (NOSCAR) White Paper, ASGE Preservation and Incorporation of Valuable endoscopic Innovations (PIVI)], and integrate this literature in the consensus POEM guidelines and perspective. These current works are largely centered on POEM operator learning curve, comparison of POEM and laparoscopic Heller myotomy (LHM) and extended application of POEM. POEM and LHM are comparable in terms of efficacy (diminished dysphagia and Eckardt score) and complications including GERD. POEM has been successfully performed in a wide variety of patients including children, those with prior achalasia therapy and those with spastic esophageal disorders. POEM has been validated as a treatment for achalasia. Issues remain regarding its longer term efficacy in comparison with LHM. Subsequent comparison trials are needed. http://links.lww.com/COG/A14.

    Full Text Available We have introduced two endoscopic treatments for early gastric cancer: endoscopic mucosal resection using a cap-fitted panendoscope (EMRC, and endoscopic laser therapy using a Nd-YAG laser. Thirty-two patients (34 lesions with gastric cancer were treated by Nd-YAG laser; including 23 initial-therapy cases (25 lesions and 9 second-therapy cases representing failures of endoscopic mucosal resection or endoscopic ethanol injection. Endoscopic laser therapy was performed safely without complication in all patients. Three patients had residual cancer, and 2 of these required surgery. Six patients died from other disease. Endoscopic laser therapy can remove early gastric cancer even when the lesion has ulceration or submucosal invasion, and has a powerful hemostatic effect. It is a safe and effective treatment for early gastric cancer.

    Full Text Available The endoscopic treatment of cancerous and precancerous lesions in the gastrointestinal (GI tract has experienced major breakthroughs in the past years. Endoscopic mucosal resection (EMR is a simple and efficient method for the treatment of most benign lesions in the GI tract. However, with the introduction of endoscopic submucosal dissection (ESD and endoscopic full-thickness resection (EFTR, the scope of lesions eligible for endoscopic treatment has been widened significantly even in the colon. These methods are now being used routinely not just for the treatment of benign lesions but also in the curative en bloc resection of early colorectal cancers. The quick, efficient, and noninvasive character of these endoscopic procedures make them not just an alternative to surgery but, in many cases, the methods of choice for the treatment of most early colon cancers and some rectal cancers.

    Posterior calcaneal exostosis treatment modalities showed many controversial opinions. After failure of the conservative treatment, surgical bursectomy and resection of the calcaneal exostosis are indicated by many authors. But clinical studies also show a high rate of unsatisfactory results with a relative high incidence of complications. The minimal surgical invasive technique by an endoscopic calcaneoplasty (ECP) could be an option to overcome some of these problems. We operated on 81 patients with an age range between 25 and 55 years, 40 males and 41 females. The radiologic examination prior to surgery documented in all cases a posterior superior calcaneal exostosis that showed friction to the Achilles tendon. All patients included in the study had neither clinical varus of the hind foot nor cavus deformities. All patients had undergone a trial of conservative treatment for at least 6 months and did not show a positive response. The average follow-up was 35.3 months (12-72). According to the Ogilvie-Harris-Score, 34 patients presented good and 41 patients excellent results, while three patients showed fair results, and three patients only poor results. All the post-operative radiographs showed sufficient resection of the calcaneal spur. Only minor postoperative complications were observed. ECP is an effective and of minimal-invasive procedure for the treatment of patients with calcaneal exostosis. After a short learning curve, the endoscopic exposure is superior to the open technique has less morbidity, less operating time, and nearly no complications; moreover, the pathology can better be differentiated.

    Full Text Available Gastrointestinal bleeding (GIB is determined in 20-30% of patients with peptic ulcer disease. Acute gastrointestinal bleeding is on the first place as the main cause of deaths from peptic ulcer ahead of the other complications. Rebleeding occurs in 30-38% of patients. Materials and Methods For getting of the objective endoscopic picture in patients with bleeding gastroduodenal ulcers we used the classification of J.A. Forrest in our study: Type I - active bleeding: • I a - pulsating jet; • I b - stream. Type II - signs of recent bleeding: • II a - visible (non-bleeding visible vessel; • II b - fixed thrombus - a clot; • II c - flat black spot (black bottom ulcers. Type III - ulcer with a clean (white down. Integrated endoscopic hemostasis included: irrigation of ulcer defect and area around it with 3% hydrogen peroxide solution in a volume of 10 - 30ml; Injection of 2-4 mL of diluted epinephrine (1:10000 for hemostasis; use of Argon plasma coagulation. Results and Discussion Integrated endoscopic stop of bleeding was performed in 57 patients who were examined and treated at the Department of Surgery from 2006 to 2012. In 16 patients bleeding was caused by gastric ulcer. Gastric ulcer type I localization according to classification (HD Johnson, 1965 was determined in 9 patients, type II - in 2 patients, type III – in 5 patients. In 31 patients bleeding was caused by duodenal peptic ulcer, in 4 patients - erosive gastritis, 1 - erosive esophagitis, and in 5 patients - gastroenteroanastomosis area peptic ulcer.

    The purpose of our study is to make a retrospective evaluation of endoscopic treatment of Haglund's syndrome using a new three portal technique. All 23 patients (25 heels) with a mean age of 27.7 years were evaluated pre-operatively and postoperatively with parallel pitch lines, the American Orthopaedic Foot and Ankle Society (AOFAS) score and the Ogilvie Harris score. The mean follow-up was 41 months (range, 30-59 months). There were no obvious complications in our study. In 22 heels, postoperative lateral radiographs showed the achievement of negative parallel pitch lines. The average AOFAS score improved from 63.3 ± 11.9 points pre-operatively to 86.8 ± 10.1 points at final follow-up. There were 14 excellent results, seven good results, two fair results and two poor results. For the Ogilvie Harris score, there were 15 excellent, seven good, one fair, and two poor results. An endoscopic procedure using the three portal technique seemed to be a safe and efficacious option for surgical treatment of Haglund's syndrome.

    In microendoscopic discectomy for spinal disorders, bone cutting procedures are performed in tight spaces while observing a small portion of the target structures. Although optical tracking systems are able to measure the tip of the surgical tool during surgery, the poor shape information available during surgery makes accurate cutting difficult, even if preoperative computed tomography and magnetic resonance images are used for reference. Shape estimation and visualization of the target structures are essential for accurate cutting. However, time-varying shape changes during cutting procedures are still challenging issues for intraoperative navigation. This paper introduces a concept of endoscopic image augmentation that overlays shape changes to support bone cutting procedures. This framework handles the history of the location of the measured drill tip as a volume label and visualizes the remains to be cut overlaid on the endoscopic image in real time. A cutting experiment was performed with volunteers, and the feasibility of this concept was examined using a clinical navigation system. The efficacy of the cutting aid was evaluated with respect to the shape similarity, total moved distance of a cutting tool, and required cutting time. The results of the experiments showed that cutting performance was significantly improved by the proposed framework.

    Full Text Available Background and ObjectiveBalloon dilatation of stricture is one of the new treatment methods for patients with Gastric Outlet Obstruction (GOO. Prevalence and underlying etiologies of GOO in various populations are different. The goal of the present study was to determine the effectiveness of endoscopic balloon dilatation and factors that could affect method advantage among patients with benign etiology for GOO. Methods Forty-five patients with symptoms of benign GOO were randomly selected. The mean age of patients was 43.7±18.1 years and 86.7% of them were men. Gastric outlet was delineated using double channel videoendoscopy. The severity of gastric pain was measured by VAS test immediately before and one month after balloon dilatation. Patients were followed after procedure weekly (for the first month and then monthly. Balloon dilatation was repeated for 27% patients during the follow up period.ResultsPatients were followed for 9.9±5.8 months. Furthermore, 71.1% were H. pylori positive. Positive response percent to endoscopic balloon dilatation was 80% and eight patients were took under surgical resection. Weight loss was seen frequently in the non-respondent group. The pain severity was significantly reduced in respondent subjects. No meaningful correlations were found between the response to balloon dilatation and positive H. pylori and cigarette smoking.ConclusionEndoscopic balloon dilatation is a safe and effective method for treating most of patients with benign gastric outlet obstruction and has favorable long-term outcome.

    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.

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

    Orbital cellulitis is a septic process of the soft tissues behind the orbital septum and is the most frequent cause of the monolateral exophthalmos in pediatrics. Approximately 90% of the orbital cellulitis in pediatrics are associated to acute ethmoiditis. From the 01.01.2001 to 31.12.2010 we treated 36 patients, less than 18 years-old affected by Chandler stage II, III, or IV orbital cellulitis. The inflammation was resolved medically in 6 patients. In the 30 cases that showed no improvement in 48-72 h, an endoscopic drainage of the pus was performed by the transethmoidal route. In children, an adenoidectomy should be included, in order to eliminate eventual infections of this lymphatic organ. Endoscopic treatment has resulted in rapid resolution of disease without any complications. In addition, postoperative discomfort is minimal, with a rapid return to daily activities.

    2014-12-21

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

    2016-01-01

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

    Full Text Available Background/aims: Per-oral endoscopic myotomy (POEM is a new minimally invasive technique to treat achalasia. Methods: 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. Results: 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. Conclusions: 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

    Greater trochanteric pain syndrome (GTPS) is a term used to describe disorders of the peritrochanteric region. This constellation of conditions includes greater trochanteric bursitis, gluteus medius (GM) tears, and external coxa saltans or snapping hip syndrome. Tears of the abductor mechanism, more specifically gluteus medius tears, have recently gained a considerable amount of interest in the orthopaedic literature. Abductor tears were first described by Bunker and Kagan in the late 1990s. They used the rotator cuff as an analogous structure to describe the pathological process associated with gluteus medius tears. Tears of the gluteus medius tendon can often be difficult to recognize. The clinical presentation is often attributed to trochanteric bursal inflammation, without any further workup. Provocative hip physical examination findings are an important key to proper diagnosis of abductor injuries. Depending on the size of the tear, patients with abductor tendon pathology may present with a Trendelenburg gait and reduced resisted abduction strength accompanied by pain. Initial noninvasive management of greater trochanteric pain syndrome includes oral or topical anti-inflammatory medication and activity modification. Physical therapy or other treatment modalities can be considered, with a focus on core strengthening, truncal alignment, and iliotibial band stretching. Gluteus medius tears have historically been repaired in an open fashion; however, the advent of new endoscopic surgery techniques has allowed for a less invasive approach. Access to the peritrochanteric space affords the surgeon with access to pathology associated with the greater trochanter, iliotibial band, trochanteric bursa, sciatic nerve, short external-rota tors, iliopsoas tendon, and the gluteus medius and minimus tendon attachments. Over the last decade, we have seen rapid technological advances in hip arthroscopy, improved diagnostic imaging and interpretation, and an improved

    To compare treatment of intestinal malrotation in newborns and infants using laparoscopy and laparotomy. For the period from January 2004 to December 2013 34 Ladd's procedures were performed. Children were divided into 2 groups by 17 patients: laparoscopic (group I) and open treatment (group II). Both groups had similar demographic and other preoperative parameters. There were significant differences in duration of operation between both groups (61 vs. 70 minutes). Nutrition was initiated earlier after mini-invasive treatment (1.5 days vs. 3 days) and the time need for full enteral nutrition was also less (4.2 days vs. 6.9 days). Hospital-stay was shorter in group I (7.7 vs. 10.2 days). Number of early postoperative complications was similar in groups. Incidence of remote complications was higher in laparotomy group but the differences were not significant. Our results showed that endoscopic correction of congenital anomalies of intestinal rotation provides better postoperative results than open surgery and can be widely used in young children.

  9. COMPARISON OF ENDOSCOPIC AND MICROSURGICAL METHODS IN THE TREATMENT OF LUMBAR DISC HERNIATIONS

    Directory of Open Access Journals (Sweden)

    SERGEY ARESTOV

    Full Text Available ABSTRACT Objective: The development of minimally invasive spine surgery leads us to reflect on the efficiency of new methods compared with older ones. In the case of endoscopic spine surgery, we always seek to compare our results using new techniques with the results of older and trusted microsurgical techniques. Unfortunately, there are few reliable studies measuring endoscopic and microsurgical approaches. We therefore decided to compare our treatment results with those of what are, in our opinion, the best and most thorough studies found. Furthermore, we found no illustrated experience in the usability of endoscopic methods. We therefore analyzed each step of the technique used, according to the practical experience with microsurgical discectomy. Methods: We compared our two-year experience of treatment of 183 patients with lumbar disc herniations using the endoscopic technique, with data reported in the literature on microsurgical minimally invasive methods. Results: Our group achieved good to excellent results in 92.9% of cases (170 patients compared to 90% reported in the literature. We compared the capabilities of endoscopic discectomy with microsurgical methods, and concluded that the endoscopic method is sufficient to perform any movement inside the surgical field that is microscopically possible. It is also possible to perform any type of spinal cord decompression, with better visualization provided by the endoscope. Conclusions: We conclude that endoscopic microdiscectomy is a good and reliable alternative, with better outcomes and more efficient usage of the approach space.

    Alteration of the bony architecture of the sinus cavities has been observed in chronic sinusitis. Plasticity of the ethmoid sinus framework after endoscopic surgery, however, is a newly described entity. The objective of this study was to determine the incidence and extent of changes in ethmoid size after ethmoidectomy. Retrospective review performed at an academic medical center. Computed tomography scans performed from 2006 through 2007 at the Massachusetts Eye and Ear Infirmary (n = 5,131) were reviewed to identify 100 consecutive patients who underwent sinus surgery and met inclusion criteria. Seven dimensions were measured for each pre- and postoperative scan (n = 200) using Voxar 3D software. Computed tomography scans performed before and 2 to 37 months after ethmoidectomy demonstrated a decrease of 1.1 +/- 1.6 mm in mean ethmoid cavity width at the level of the cribriform plate and posterior globe after surgery (P 1 mm decrease in mean ethmoid width, and six patients (6%) had a decrease of >2 mm (mean 3.1 +/- 0.9 mm). These findings seemed to be the result of postoperative bowing of the medial ethmoid walls with a corresponding increase in orbital volume. These volumetric changes resulted in a postoperative subclinical retrodisplacement (enophthalmos) of the globes (mean 0.2 +/- 0.8 mm, P = .008). The extent of surgery, including performance of frontal recess dissection (P = .007) and total ethmoidectomy (P = .021) were found to be independent predictors of the observed changes in sinus dimensions. Postsurgical plasticity of the ethmoid cavity is a new concept supported by observed changes in sinus dimensions after ethmoidectomy. These changes may reflect a loss of internal structural support and forces of contracture during the postoperative healing period.

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

    2001-05-01

    We describe a comprehensive approach to the endoscopic treatment of calcaneal spur syndrome developed by the Arthroscopic Group of the Orthopedic Service of Hospital Hermanos Ameijeiras in Havana, Cuba. The surgical technique involves treatment of the heel spur and plantar fasciitis commonly found in calcaneal spur syndrome, but it also addresses adjacent calcaneal periostitis and allows decompression of the nerve to the abductor digiti quinti. Medial endoscopy and lateral instrumentation are used in a sequential approach with exposure and debridement of the posterior roof of the calcaneal arch, followed by removal of the calcaneal spur, lateral to medial release of the medial 75% of the plantar fascia, and if necessary, debridement of the calcaneal tuberosity periosteum. This technique was used in a prospective case series from June 1997 to May 1998 to treat a select group of 38 feet in 30 patients who reported unacceptable levels of pain despite 5 months of conservative treatment, which included an aggressive 8-week physical therapy program prescribed by the treating physician. Good to excellent results were obtained at 3 months postoperatively in all patients with regard to pain relief and return to normal activity, although 5 patients required a short course of physical therapy to resolve symptoms brought on by sports, trauma, or impact loading before 1-year follow-up, at which time all patients reported good to excellent results. Complications included 3 superficial wound infections cured by oral antibiotics and 2 transient lateral paresthesias that resolved with rest and nonsteroidal inflammatory medications. The described technique may provide a useful method for treating refractory heel spur syndrome and warrants further study.

    There is no consensus as to the best treatment for Mallory-Weiss tears with severe bleeding. Endoscopic ligation is an inexpensive, readily available, and easily learned technique, in contrast to conventional thermocoagulation or hemoclipping. To evaluate the utility of endoscopic ligation, we performed this technique during emergency endoscopy to treat severe bleeding from Mallory-Weiss tears in four patients in our hospital with continuous active bleeding from Mallory-Weiss tears. The patients were all male with an average age of 40.5 years. Symptoms associated with increased intra-abdominal pressure, including retching and vomiting were reported by all patients. The bleeding points were aspirated and controlled by endoscopic ligation, and complete hemostasis was achieved in all cases. We conclude that endoscopic ligation is easy to perform and may provide an alternative treatment for severe bleeding from Mallory-Weiss tears.

    In patients with infected necrotising pancreatitis there is a significant risk (40%) of complications and mortality with the surgical step-up approach. This approach consists of percutaneous retroperitoneal drainage, if necessary followed by video-assisted retroperitoneal débridement. An alternative treatment is an endoscopic step-up approach consisting of endoscopic transluminal drainage, if necessary followed by endoscopic transluminal necrosectomy. The Dutch Pancreatitis Study Group has recently started the nationwide randomized TENSION-trial, in which in 98 patients the endoscopic step-up approach is compared with the surgical method. The primary endpoint is a composite of mortality and major morbidity (new onset organ failure, bleeding, perforation of a hollow organ or incisional hernia for which intervention is needed).

    Full Text Available Purpose. The goal of this review is to present current indications, injectable agents, techniques, success rates, complications, and potential future applications of endoscopic treatment for vesicoureteral reflux (VUR in children. Materials and Methods. The endoscopic method currently achieving one of the highest success rates is the double hydrodistention-implantation technique (HIT. This method employs dextranomer/hyaluronic acid copolymer, which has been used in pediatric urology for over 10 years and may be at present the first choice injectable agent due to its safety and efficacy. Results. While most contemporary series report cure rates of greater than 85% for primary VUR, success rates of complicated cases of VUR may be, depending on the case, significantly lower. Endoscopic treatment offers major advantages to patients while avoiding potentially complicated open surgery. As the HIT method continues to be applied to complex cases of VUR and more outcome data become available, the indication for endoscopic treatment may exceed the scope of primary VUR. Conclusions. Endoscopic injection is emerging as the treatment of choice for VUR in children.

    Upper gastrointestinal bleeding is still an important clinical problem, even though about 80% of bleedings due to peptic lesions stop spontaneously. Starting from 1970, a lot of endoscopic hemostatic procedures has been developed and employed with good results, but, at present, the key problem is represented by the selection and management of the patients at highest risk of rebleeding. This work reviews both techniques and devices most commonly used, but at present none of them can be considered actually better than the other ones. According to the SIED (Società Italiana di Endoscopia Digestiva) guidelines, the techniques of choice should be cheap, effective, safe and easy to perform, the pivotal role in determining the success rate of endoscopic hemostasis being played by the endoscopist's experience.

    To describe endodontic treatment for a rare case of gemination. A case of complex endodontic treatment in a geminated tooth is presented. With the assistance of microinstruments and magnification devices, a geminated maxillary second molar was successfully treated. In such a case, ultrasonic tips and the use of an endoscope were essential to detect the peculiar anatomy of the tooth involved. Knowledge of anomalies concerning fused teeth is essential. Using an endoscope as a magnification device is useful during the inspection of pulp chambers. Ultrasonic tips are safe and useful to detect canal orifices.

    Full Text Available Abstract Background Recently, several new endoscopic treatments have been used to treat patients with Barrett's esophagus with high grade dysplasia. This systematic review aimed to determine the safety and effectiveness of these treatments compared with esophagectomy. Methods A comprehensive literature search was undertaken to identify studies of endoscopic treatments for Barrett's esophagus or early stage esophageal cancer. Information from the selected studies was extracted by two independent reviewers. Study quality was assessed and information was tabulated to identify trends or patterns. Results were pooled across studies for each outcome. Safety (occurrence of adverse events and effectiveness (complete eradication of dysplasia were compared across different treatments. Results The 101 studies that met the selection criteria included 8 endoscopic techniques and esophagectomy; only 12 were comparative studies. The quality of evidence was generally low. Methods and outcomes were inconsistently reported. Protocols, outcomes measured, follow-up times and numbers of treatment sessions varied, making it difficult to calculate pooled estimates. The surgical mortality rate was 1.2%, compared to 0.04% in 2831 patients treated endoscopically (1 death. Adverse events were more severe and frequent with esophagectomy, and included anastomotic leaks (9.4%, wound infections (4.1% and pulmonary complications (4.1%. Four patients (0.1% treated endoscopically experienced bleeding requiring transfusions. The stricture rate with esophagectomy (5.3% was lower than with porfimer sodium photodynamic therapy (18.5%, but higher than aminolevulinic acid (ALA 60 mg/kg PDT (1.4%. Dysphagia and odynophagia varied in frequency across modalities, with the highest rates reported for multipolar electrocoagulation (MPEC. Photosensitivity, an adverse event that occurs only with photodynamic therapy, was experienced by 26.4% of patients who received porfimer sodium. Some

    Full Text Available Gastric bezoars are rare and are usually found incidentally. They can sometimes cause severe complications, including gastric outlet obstruction (GOO or gastric pneumatosis (GP. In cases of bezoars with GP, the optimal treatment strategy has not yet been defined. We report the case of an 89-year-old man with a history of type 2 diabetes mellitus and hypertension who presented to our emergency room with a 2-day history of upper abdominal pain, nausea, and vomiting. Physical examination revealed no rebound tenderness or guarding, and laboratory values revealed no elevation of the serum lactate level. A computed tomography scan of the abdomen showed a dilated stomach with significant fluid collection, GOO, and GP due to a 42 × 40 mm mass composed of fat and air densities. Emergency esophagogastroduodenoscopy revealed two gastric bezoars, one of which was incarcerated in the pyloric region. We used various endoscopic devices to successfully break and remove the bezoars. We used endoscopic forceps and a water jet followed by an endoscopic snare to cut the bezoars into several pieces and remove them with an endoscopic net. Follow-up endoscopy confirmed that the gastric bezoar had been completely removed. As seen in this case, endoscopic treatment may be a safe and viable option for the extraction of gastric bezoars presenting with GOO and GP.

    Full Text Available Upper gastrointestinal bleeding (UGB is a common medical emergency problem with significant morbidity and mortality. The aim of this paper is to establish the incidence of upper gastrointestinal bleeding in relation to sex and age, determine the prevalence of bleeding lesions and perform analysis of bleeding peptic ulcer in relation to the location, age, gender, Forrest classification and the need for endoscopic hemostasis. Thе prospective study included 70 patients with UGB, 42 men and 28 women, mean age 68.64±13.66 years. The diagnosis of bleeding lesions was made exclusively by means of esophagogastroduodenoscopy. Forrest classification was used in the evaluation of the activity of bleeding ulcers of the stomach and duodenum. The largest number of bleeding patients was of male sex (60%. Bleeding most commonly occurred in patients older than 60 years (84.29%. Statistically, female patients were significantly older than patients of male gender (p=0.001. The most common cause of bleeding was peptic ulcer (65.71%. The average age of patients with gastric ulcer was 70.57±15.68 years, with a duodenal ulcer 63.78±16.70 years. In the duodenum, Forrest Ib, IIa and IIb ulcers were usually confirmed, whereas Forrest IIc ulcers were identified in the stomach. Endoscopic hemostasis was required in 55.56% of patients with duodenal and in 23.81% of patients with gastric ulcer. The incidence of UGB is higher in men and it increases with age. The most common cause of bleeding is ulcer disease. Patients with gastric ulcer are older than patients with duodenal ulcer, while both gastric and duodenal ulcers are found in the oldest patients. Duodenal ulcers cause serious bleeding and more often require endoscopic hemostasis.

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

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

    Full Text Available Objective To analyze the efficacy of endoscopic histoacryl injection in the treatment of gastric variceal bleeding caused by regional portal hypertension. Methods The endoscopic features and efficacy of endoscopic histoacryl injection were examined and compared in two groups of patients admitted to our hospital from June 2012 to December 2012. One of the groups included 6 patients with gastric variceal bleeding caused by regional portal hypertension and the other group included 6 patients with gastric variceal bleeding caused by hepatitis B cirrhosis-related portal hypertension. Between-group comparison of categorical data was made by Fisher′s test. Results In patients with regional portal hypertension, five of them had severe isolated gastric varices (IGV and one had severe IGV with mild esophageal varices. All six patients with hepatitis B cirrhosis-related portal hypertension had severe IGV and the endoscopic features were similar to those of patients with regional portal hypertension. Significant differences were observed between the group with regional portal hypertension and the group with hepatitis B cirrhosis related portal hypertension in short-term response rate (1/6 vs 6/6, P=0.015 and long-term response rate (0/6 vs 5/6, P=0.015. Conclusion The gastric varices caused by regional portal hypertension has a fast progression rate and a high bleeding risk. The efficacy of endoscopic histoacryl injection in patients with this type of gastric varices is poor.

    Objectives  The purpose of this study is to report health utility scores for patients with olfactory groove meningiomas (OGM) treated with either the standard transcranial approach, or the expanded endonasal endoscopic approach. Design  The time trade-off technique was used to derive health utility scores. Setting  Healthy individuals without skull base tumors were surveyed. Main Outcome Measures  Participants reviewed and rated scenarios describing treatment (endoscopic, open, stereotactic radiation, watchful waiting), remission, recurrence, and complications associated with the management of OGMs. Results  There were 51 participants. The endoscopic approach was associated with higher utility scores compared with an open craniotomy approach (0.88 vs. 0.74; p  < 0.001) and watchful waiting (0.88 vs.0.74; p  = 0.002). If recurrence occurred, revision endoscopic resection continued to have a higher utility score compared with revision open craniotomy (0.68; p  = 0.008). On multivariate analysis, older individuals were more likely to opt for watchful waiting ( p  = 0.001), whereas participants from higher income brackets were more likely to rate stereotactic radiosurgery with higher utility scores ( p  = 0.017). Conclusion  The endoscopic approach was associated with higher utility scores than craniotomy for primary and revision cases. The present utilities can be used for future cost-utility analyses.

    Cholelithiasis and choledocholithiasis occur frequently in pregnancy and their management can be complicated. Traditional endoscopic retrograde cholangiopancreatography (ERCP) is the first line treatment for choledocholithiasis, but in addition to its baseline risks, fluoroscopy poses an additional radiation risk to the fetus. Endoscopic ultrasound (EUS) is an accurate modality for detecting common bile duct stones, but its role has not been defined in pregnancy. We describe an alternative management strategy to conventional ERCP in a pregnant patient with choledocholithiasis and cholangitis detected using EUS and choledochoscopy. PMID:20653072

    Full Text Available Bouveret's syndrome is a rare condition of gastric outlet obstruction resulting from the migration of a gallstone through a choledochoduodenal fistula. Due to the large size of these stones and the difficult location in which they become impacted, endoscopic treatment is unsuccessful and most patients require surgery. We report the case of an elderly male who presented with nausea and hematemesis, and was found on CT scan and endoscopy to have an obstructing gallstone in his duodenal bulb. After several endoscopic sessions and the use of multiple instruments including a Holmium: YAG laser and electrohydraulic lithotripter, fragmentation and endoscopic removal of the stone were successful. We believe this to be the first case of Bouveret's syndrome successfully treated by endoscopy alone in the United States. We describe the difficulties encountered which necessitated varied and innovative therapeutic techniques.

    Full Text Available Osteoma is one of the most common tumors of the cranial vault and the facial skeleton. For osteoma in the facial region, endoscopic resection is widely used to prevent surgical scarring. Tumors in a total of 14 patients were resected using an endoscopic holmium-doped yttrium aluminium garnet (Ho:YAG laser with a long flexible fiber. Aside from having the advantage of not leaving a scar due to the use of endoscopy, this procedure allowed resection at any position, was minimally invasive, and caused less postoperative pain. This method yielded excellent cosmetic results, so the endoscopic Ho:YAG laser is expected to emerge as a good treatment option for osteoma.

    Epidermolysis bullosa acquisita (EBA) is a rare auto-immune dermatologic disease, produced by auto-antibodies against colagen VII. We report a 44 years old male patient with EBA diagnosed 15 years before, who presented with progressive disphagia, being diagnosed an esophageal involvement of EBA. The patient was submitted to endoscopic treatment with thermoplastic bougie dilation and intralesional corticosteroid injection. The patient improved clinically with recovery of nutritional status. Esophageal involvement in EBA is very rare and its reason is still unknown. Endoscopic approach must be cautiously performed with the use of small diameter endoscopes, small caliber dilators, intralesional injection of corticosteroid and enteral tube in order to minimize the risks of complications, as well as esophageal rest from food trauma and better reparatory molding of the epithelium.

Methods: A descriptive, comparative, ambispective and longitudinal study. The clinical records of patients who underwent herniated disc surgery were reviewed from March 2010 to March 2015. Inclusion criteria were individuals of both sexes, aged 18-65 years, with disc herniation diagnosis by MRI, evocative discography (pain and clinical evaluation. The variables were analyzed by VAS, Oswestry disability index for functional assessment and Macnab criteria for modified retrospective cross clinical classification. Results: 161 patients were included, 81 female and 80 male, aged between 18 and 65 years with severe (83.8% and moderate (16.2% disability according to the Oswestry disability index; the total of excellent results was 83.8%, 9.5% were good, 4.8% were median and 1.9% were poor results, according to the Macnab criteria; the average time of surgery was 84 minutes per procedure, and the postoperative average bleeding was 65 ml. Of the total, 87.4% of the patients were on an outpatient basis and 7.6% had a short hospital stay.. Conclusion: It was found that percutaneous endoscopic nucleoplasty with radiofrequency technique is a procedure that offers great benefits for patients with lumbar disc herniation, including performing it under local anesthesia, with clear visualization of the surgical field, minimal pain, little bleeding, shorter operative time, does not cause instability of anatomical structures and has minimal rate of complications.

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

    To present to report the first case of ureteral lithiasis resolved using a new endoscopic approach, which we call microureteroscopy (m-URS) and attempts to reduce the ureteral damage caused by conventional instrumentation. We selected a 53-year-old patient with a 16-mm calculus in the right distal ureter. For endoscopic access, we used a 4.8 Fr sheath from the microperc set and fragmented the stone with a 230-micron laser fiber. Complete fragmentation of the stone was achieved. We placed a JJ catheter due to significant ureteral edema. The surgical time and postsurgical stay were 156minutes and 24hours, respectively. There were no complications, the requirements for analgesia were minimal, and the patient was free of residual stones. The m-URS technique is feasible, simple and effective for the treatment of pelvic ureteral lithiasis in women and optimizes minimal invasion, with results that can be comparable to conventional endoscopic techniques in terms of ease of access and quality of endoscopic vision without affecting the resolution capacity. Larger studies and greater technological development is needed to define the definitive role of this procedure. Currently, its major limitations lie in the treatment of proximal ureter lithiasis and in the treatment of men. This technique could also be a viable alternative for pediatric patients.

    There is limited data on whether scoring systems can be used to predict clinical outcomes in patients with upper gastrointestinal bleeding due to Mallory-Weiss syndrome (MWS). We aimed to evaluate whether the Glasgow-Blatchford score (GBS) could be effective in predicting clinical outcomes of bleeding MWS and to investigate the predictive ability of the Forrest classification for rebleeding and assess the effective endoscopic modalities for bleeding control in MWS. From January 2004 to December 2012 168 patients were diagnosed with MWS in the Asan Medical Center Emergency Department. We analyzed their clinical outcomes, including endoscopic treatment, transfusion and admission as well as the rates of rebleeding and mortality using GBS and the Forrest classification, retrospectively. Endoscopic treatment was applied to patients. The GBS was significantly higher in patients treated with endoscopic therapy than in the conservative treatment group (6.8 ± 3.7 vs 5.1 ± 4.7, P = 0.011). In patients with a GBS of >6 the rates of endoscopic treatment and rebleeding and the need for transfusion and admission were significantly higher (all P < 0.05). The Forrest classification was able to predict recurrent bleeding (area under the receiver operating characteristic curve 0.723, 95% confidence interval 0.609-0.836, P = 0.025). Hemoclip-based therapy and band ligation achieved higher success rates than did injection therapy alone in preventing rebleeding (96.4%, 88.9% and 71.4%, P = 0.013). In MWS, GBS might be useful for predicting clinical outcomes and the Forrest classification in predicting recurrent bleeding. © 2016 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

    Full Text Available ObjectiveTo explore risk factors of early rebleeding after endoscopic treatment of gastroesophageal varices by retrospectively analyzing cases and outcomes from the China-Japan Friendship Hospital. MethodsThree hundred cases of esophagus and/or gastric varices that had received endoscopic therapy between November 1995 and December 2010 were enrolled in the study. The cases were divided into two groups according to presence or absence of early rebleeding, defined as rebleeding within 24 h to six weeks of the operative procedure. Associations with variables of the endoscopic procedure, as well as laboratory and imaging findings, were analyzed by forward stepwise logistic regression analysis to identify independent risk factors of early rebleeding. ResultsPatients experiencing early rebleeding after endoscopic therapy were more likely to be male (P=004, ascites-positive (P=0032, to have a larger portal vein diameter (P=0046, and higher levels of serum creatinine (P=0049 and serum sodium (P=0033 Two significant candidate variables were identified: ascites-positivity (odds ratio (OR=3505, 95% confidence interval (CI: 1169, 10512, P=0025 and higher serum creatinine (OR=1016, 95% CI: 1002, 1031, P=0028. ConclusionEarly rebleeding after endoscopic therapy of gastroesophageal varices is mainly affected by the presence of ascites and higher serum creatinine. Patients with these risk factors should be paid careful attention before and after the endoscopic procedure.

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

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

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

    To present the clinical and radiographic outcomes of 140 patients with pituitary adenomas treated by an endoscopic endonasal approach (EEA) over a period of 4 years. A retrospective analysis was performed between 2011 and 2014. Pre and post operative MRI, ophtalmological assessment, endocrinological laboratory evaluation and surgical morbidity and mortality were assessed. 57,9% of the patients had functional tumors (n=81), acromegaly being the most frequent sub-type (29.3%). 78.6% of the lesions were macroadenomas (n=110) of which 56.4% (n=62) involved the cavernous sinus, 61 patients presented with visual field defects (44%) of which 50.8% of patients showed improvement after surgery. Gross total removal was achieved in 60% of the cases. Hormonal remission was achieved in the 75% of the patients with functional tumors. The morbidity rate was 15% and one patient died after surgery (mortality 0.7%). EEA is a safe and effective tool to treat pituitary adenomas. The main limitation for complete surgical resection is the cavernous sinus invasion. Copyright © 2016 Sociedad Española de Neurocirugía. Publicado por Elsevier España, S.L.U. All rights reserved.

    The aim of this study was to determine the efficacy and complications of postoperative endoscopic retrograde cholangiopancreatography (ERCP) in confirming and treating choledocholithiasis found at intraoperative cholangiography during laparoscopic cholecystectomy. Patients who had undergone ERCP following a cholecystectomy between 2008 and 2011 with an indication of intraoperative cholangiography findings consistent with choledocholithiasis were identified from a prospectively collected database of a single endoscopist. Deep biliary access rate, confirmation of choledocholithiasis, clearance rate of bile duct stones, delay between cholecystectomy and postoperative ERCP, and the complication rates following the procedure were analysed. The median age of the 41 patients (16 male, 25 female) was 42 years (range: 18-82 years). Sixteen surgeons performed the operations with a median delay of 6 days (range: 1-103 days) between cholecystectomy and postoperative ERCP. Common bile duct access was achieved in 100% of the patients, with ERCP taking a median time of 16 minutes (range: 6-40 minutes). Initial ERCP confirmed the presence of a stone in 30 patients (73%) and successful stone removal occurred in 28 of these 30 patients (93%) during the first ERCP and in the remaining 2 on a subsequent ERCP. Following ERCP, two patients (4.9%) experienced extended hospital stays for four and eight days owing to complications, including one patient (2.4%) with mild acute pancreatitis. This study demonstrates that postoperative ERCP is highly effective in both confirming and treating choledocholithiasis. However, there is a significant risk of short-term complications that must be taken into consideration when deciding management.

    Endoscopic Nd-YAG laser treatment and adjuvant therapy were performed in 44 cases with metastatic lesions of airway. The best results were obtained in 31 cases (93.9%) out of 33 cases complaining of ventilatory disturbance in which endoscopic Nd-YAG laser treatment was indicated as an emergency procedure. In most of these cases with metastatic lesions of airway consisted of respiratory tract invasion from mediastinal lymph nodes in cases of esophageal cancer or lung cancer. In these cases, after laser treatment for ventilatory disturbance, the patients condition improved to the extent that adjuvant therapy could be performed. Adjuvant therapy was performed in 38 cases, there were 7 cases treated surgically (resection of the metastatic lesions of airway in 3 cases, tracheal tube stent operation in 4 cases 0, 28 radiotherapy in 28 cases (Linac irradiation in 24 cases, 60 Co intraluminal irradiation of the trachea in 4 cases 0, and 32 cases were treated with chemotherapy. Tracheal tube stent operation was useful for maintenance of the tracheal lumen following laser treatment, and 60 Co intraluminal irradiation was effective for the residual intratracheal tumor. The 1-year survival rate of 44 cases with metastatic lesions of airway was 42% and the 2-year survival rate was 22%, so this result suggested endoscopic Nd-YAG laser treatment and adjuvant therapy for metastatic lesions of airway was useful to prolong survival time. However the main value of this modality is for the rapid relief of severe ventilatory disturbance due to obstructive airway lesions. (author)

    To assess the clinical effects of combined endoscopic-laparoscopic technique for one-stage treatment of cholelithiasis with concomitant choledocholithiasis. A retrospective analysis was conducted of the clinical data of 30 patients (Group A) with cholelithiasis and choledocholithiasis receiving one-stage laparoscopic cholecystectomy (LC) combined with intraoperative encoscopic retrograde cholangio-pancreatography (ERCP) and 32 patients (Group B) receiving LC combined with 1aparoscopic common bile duct exploration. The operative time, blood loss, conversion to open surgery rate, time to postoperative ambulation, calculi residual rate, hospitalization cost and length of hospital stay were analyzed comparatively. There were statistically differences between the two groups in hospitalization cost and length of hospital stay (P0.05). Combined endoscopic-laparoscopic techniques can be a safe and feasible option for one-stage treatment of concomitant cholelithiasis and choledocholithiasis to allow rapid postoperative recovery with a shortened hospital stay.

    In the article, the specially designed devices for pre-sterilization treatment of laparoscopic, endoscopic and other long-length surgical equipment from organic compounds (blood and alkali) in ultrasonic tank-container with ozone has been proposed. The first device was equipped with a bath (up to 30 l), ten ultrasonic emitters with a total power 300 W, and four modular ozone generators based on dielectric barrier discharges. The second device equipped with 3.5 liter volume bath was also designed having a glass pipe 1 meter long, 8 cm in diameter with one ozone module and immersion ultrasonic emitter. During treatment, the ozonized water was injected both into the internal and external surfaces of endoscopes. The output ozone concentration reached 30 mg/l with dry air flow rate 0.3 l/min. Phenolphthalein test and ''Delatest'' solution method determined the remains of alkali and blood, respectively.

    Hirschsprung's disease (HD) is a congenital disorder characterized by the absence of intrinsic ganglion cells in submucosal and myenteric plexuses of the hindgut; and presents with constipation, intestinal obstruction and/or megacolon. HD commonly involves the rectosigmoid region (short segment HD), although shorter and longer variants of the disease are described. Standard treatment involves pull-through surgery for short segment HD or posterior anorectal myotomy in selected ultrashort segment candidates. Third space endoscopy has evolved during the past few years. Per oral endoscopic myotomy and per oral pyloromyotomy are described for treatment of achalasia cardia and refractory gastroparesis, respectively. Using the same philosophy of muscle/sphincter disruption for spastic bowel segments, per rectal endoscopic myotomy could be considered as a treatment option for short segment HD. A 24-year-old male patient presented with refractory constipation since childhood, and habituated to high-dose laxative combinations. Diagnosis was confirmed as adult short segment HD by barium enema, colonoscopic deep suction mucosal biopsies and anorectal manometry. Histopathology confirmed aganglionosis in the distal 15 cm. By implementing principles of third space endoscopy, per rectal endoscopic myotomy 20 cm in length was successfully carried out. At 24-week follow up, the patient reported significant relief of constipation and associated symptoms. Sigmoidoscopy, anorectal manometry and barium enema confirm improved rectal distensibility and reduced rectal pressures. The present case report describes the first human experience of per rectal endoscopic myotomy for successful treatment of adult short segment HD. © 2016 Japan Gastroenterological Endoscopy Society.

    Full Text Available Background. Damage to the urethra in damaged pelvic bones in children is marked less than in adults (less than 1 % (Tarman G.J. et al., 2002. Post-traumatic urethral stricture in children is a quite rare and complex urologic pathology. Due to anatomical features, treatment for urethral stricture in children is different from its treatment in adults (Onen A. et al., 2005; Nerli R.B. et al., 2008; Ranjan P. et al., 2011. M.M. Koraitim (2012 described the experience of treating 20 patients with complications after transperyneal urethral plasty. The author noted that in the absence of need for reconstruction of the bladder neck, it is quite effective to use endoscopic incision of urethral stricture. T.E. Helmy, A.T. Hafez (2013 also described the results of the successful application of endoscopic equipment (direct visual urethrotomia after open urethroplasty. The important point that leads to finding effective minimally invasive treatments for post-traumatic urethral strictures in children is the development of erectile dysfunction in the future, the incidence of which, according to some authors, (Koraitim M.M., 2014 is up to 47 %. The aim of the study: based on the available published data and own treatment outcomes in children with posterior urethral strictures, to establish the role of endoscopic treatment of this complex pathology as a method of prevention and treatment of neuromuscular dysfunction of the bladder.

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

    Endoscopic treatment for post-prostatectomy urinary incontinence has gained popularity using several inject-able bulking materials. The current study reports our experience with endoscopic submucosal injection of dextranomer/hyaluronic acid copolymer for treatment of post-prostatectomy incontinence due to sphincteric deficiency. A total of 14 patients with post-prostatectomy urinary incontinence; 13 post-trans urethral resection of prostate (TURP) and 1 post-open prostatectomy, were enrolled. The patients aged between 59-85 years. Preoperative evaluation included multi-channel video urodynamics. Patients who had verified intrinsic sphincteric deficiency, adequate bladder capacity, absent unhibited detrusor contractions and minimal or no post void residual (PVR) urine were selected for injection therapy. The standard 4 quadrant sub-mucosal injection technique was utilized. Follow-up was scheduled at 1 month after each injection and at 6-months interval thereafter. A total of 25 procedures were done. Seven patients (50%) received single injection, 3 patients (21.4%) required 2 injections and 4 patients (28.6%) needed 3 injections. The mean volume of injected material was 3.7 mL per procedure (range 2-8). The mean operative time was 30 minutes (range 15-60). The procedure was performed without intraoperative adverse events or significant postoperative complications. The overall cure rate, significant improvement rate and failure rate were 28.6%, 35.7% and 35.7%.respectively, with a total of 64.3% considered as success (cured or significantly improved). At 1 year of follow-up, 71.4% of the patients (cured or improved) demonstrated persistence of the favourable outcome. Endoscopic treatment of post prostatectomy incontinence due sphinteric deficiency is a minimally invasive, safe and successful procedure. Endoscopic submucosal injection of dextranomer has shown a durable favorable outcome at 1 year of follow-up. (author)

    Although bezoar dissolution by Coca-Cola® has been described in case reports and case series, to the best of our knowledge, the usefulness of other cola products such as Pepsi-Cola® has never been reported in the English literature. An 86-year-old Taiwanese man was diagnosed with a gastric bezoar. Endoscopic fragmentation with a polypectomy snare was attempted twice but failed to remove the bezoar. Subsequently, 500 mL of Pepsi NEX Zero® was administered daily for 4 days via nasogastric tube. The bezoar was softened and successfully fragmented by the polypectomy snare and needle-knife devices on the third attempt. This report presents the first case of a gastric bezoar successfully treated by endoscopic fragmentation in combination with Pepsi-Cola® administration, suggesting the possible utility of cola beverages in bezoar treatment, regardless of product brands.

    Complications associated with choledocholithiasis are uncommon during pregnancy. However, when it occurs, the morbidity and mortality related for the product and the mother increases, so a proper treatment is imperative in these patients. A 25-year-old pregnant woman on her second trimester. The current condition was started four days prior to the hospital admission with abdominal pain in the right upper quadrant with nausea and vomit.Twenty-four hours later jaundice and dark urine is observed. Physical examination shows scleral jaundice, right upper quadrant abdominal pain without peritoneal irritation. Uterus at umbilicus level without uterine activity. Uterus at umbilicus level without uterine activity. Laboratory tests showed elevated bilirubin and transaminases without leukocytosis; ultrasound reported live intrauterine unique product, with a heart rate of 128 beats per minute, gallbladder with multiple images inside that cast acoustic shadowing, and a 10 mm common bile duct dilated bile duct with dilatation of intrahepatic bile ducts. It was perform laparoscopic cholecystectomy with intraoperative cholangiography and placement of a transcystic jaguar guide for selective cannulation of the common bile duct. Intraoperative endoscopic retrograde cholangiopancreatography was performed with endoscopic stone extraction. The outcome was satisfactory with a hospital discharge at 48 hours. Current evidence has shown that the combined use of laparoscopy and therapeutic endoscopic cholangiography in one step is effective for the treatment of choledocholithiasis, decreasing the risk of complications associated with cannulation of the bile duct.

    Purpose: Evaluation of a percutaneous transhepatic treatment of symptomatic choledocholithiasis in bile ducts that cannot be reached with the endoscope. Methods: From January 1996 to August 2000 a transhepatic extraction of biliary calculus was performed in four patients. Endoscopic retrograde cholangiography (ERC) was not successful in any of the cases. Clinical symptoms were icterus in four cases, additional cholangitis or colics in two cases. First, a ballon dilation of the papilla was performed by a percutaneous transhepatic approach. For removal of bile duct stones, occlusion catheters and Dormia baskets were used. Technical success was defined as complete removal of bile duct stones. Clinical success was defined as normalization of cholestasis and inflammation parameters. In the follow-up an ultrasound examination was performed and blood samples were taken for control of cholestasis parameters. Results: In all four cases treatment was technically and clinically successful. For complete removal of biliary calculus a second intervention was necessary in two cases. In each case an internal to external drainage was left over a mean of 7 days (3 - 13 days). In the mean follow-up of 30.5 months (6 - 50 months) all patients had persistent relief of symptoms. No further interventions were necessary. No complications were present. Conclusion: Percutaneous transpapillary extraction of biliary calculus is an effective alternative to surgery in patients with bile ducts, that cannot be reached with the endoscope. (orig.) [de

    For chronic rhinitis that is refractory to medical therapy, surgical intervention such as endoscopic vidian neurectomy (VN) can be used to control the intractable symptoms. Lasers can contribute to minimizing the invasiveness of ENT surgery. The aim of this retrospective study is to compare in patients who underwent diode laser-assisted versus traditional VN in terms of operative time, surgical field, quality of life, and postoperative complications. All patients had refractory rhinitis with a poor treatment response to a 6-month trial of corticosteroid nasal sprays and underwent endoscopic VN between November 2006 and September 2015. They were non-randomly allocated into either a cold instrument group or a diode laser-assisted group. Vidian nerve was excised with a 940-nm continuous wave diode laser through a 600-μm silica optical fiber, utilizing a contact mode with the power set at 5 W. A visual analog scale (VAS) was used to grade the severity of the rhinitis symptoms for quality of life assessment before the surgery and 6 months after. Of the 118 patients enrolled in the study, 75 patients underwent cold instrument VN and 43 patients underwent diode laser-assisted VN. Patients in the laser-assisted group had a significantly lower surgical field score and a lower postoperative bleeding rate than those in the cold instrument group. Changes in the VAS were significant in preoperative and postoperative nasal symptoms in each group. The application of diode lasers for vidian nerve transection showed a better surgical field and a lower incidence of postoperative hemorrhage. Recent advancements in laser application and endoscopic technique has made VN safer and more effective. We recommend this surgical approach as a reliable and effective treatment for patients with refractory rhinitis.

    Full Text Available Objective. We report the first utilisation of transnasal marsupialization to treat a keratocystic odontogenic tumor in the maxillary sinus of a 37-year-old man. Case Report. A 37-year-old man presented with a nasal discharge and right odontalgia. Computed tomography revealed an expanding cystic lesion with a calcificated wall containing an impacted tooth in the right maxillary sinus. The diagnosis was keratocystic odontogenic tumor. Transnasal marsupialization was performed using endoscopic sinus surgery to enlarge the maxillary ostium and remove a portion of the cystic wall. Pathological findings included lining squamous epithelium and inflammation. The remaining tumor shrank, becoming free of infection after surgery, without proliferation. Conclusion. Transnasal marsupialization using endoscopic sinus surgery is effective in treating keratocystic odontogenic tumors. It offers minimal surgical invasion and reductive change, making it advantageous for complete removal with fewer complications in the bones and surrounding tissue in the case of secondary surgery.

    Full Text Available The authors evaluated the role of endoscopic techniques in the diagnosis and in the potential treatment of neuroendocrine tumors (NET localized in the gastro-entero-pancreatic system, on the basis of their experience and of the international literature. NET are rare tumors that arise from neuroendocrine cells of the gastrointestinal tract and pancreas. It is a possibility that both the digestive endoscopy and EUS play an important role in the diagnosis, staging and surveillance of this disease. In some cases, especially in the early stages, surgical endoscopy allows the treatment of such tumors.

The generalized morphological description of the perforating arteriovenous structures of the leg is presented as a vascular formation including the arteries and veins put in the general connective-tissue vagina and beginning from the profound or/and muscular veins and arteries. Operations were made on 56 patients aged 25-76 years, 40 of them had postthrombotic disease, 16 - varicose disease. The endoscopic subfascial dissection of the perforating veins was conducted using the standard set of tools for laparoscopic surgery of K. Storz Company. During the surgical procedure the perforating vascular bunch in the subfascial space was isolated, the veins were intersected electrosurgically, the other parts of the vascular bunch were preserved. On the average, the patients were in the hospital for 7+/-2 days. Trophic ulcers healed up during 7-30 days. Long-term results were good in 30%, satisfactory in 64%, unsatisfactory - in 6%. So, the selective endoscopical dissection of perforating veins is thought to be a radical, minimally invasive, anatomically and functionally reasonable method of elimination of the horizontal venous blood regurgitation. This technique resulted in a considerably decreased number of postoperative complications and less time of hospital treatment.

    This study was aimed to determine the risk factors of endoscopic variceal ligation-(EVL) induced ulcer bleeding.The prevalence of EVL-induced ulcer bleeding is reported to be 3.6%. However, there are only limited reports of this serious complication, and the risk factors and the treatment methods are not well established.A total of 430 patients who had undergone EVL in Chonnam National University Hospital from January 2014 to October 2016 were studied. EVL was performed for prophylaxis or acute hemorrhage. The patients were classified into 2 groups: a bleeding group (n = 33) and a non-bleeding group (n = 397). The patients who had endoscopically confirmed EVL-induced ulcer bleeding were included in the bleeding group.EVL-induced ulcer bleeding occurred in 7.7% (n = 33) of the patients. In a multivariate analysis, model for end-stage liver disease (MELD) score >10 (odds ratio [OR]: 3.42, 95% confidence interval [CI]: 1.10-10.64), concomitant GV F3 (OR: 14.1, 95% CI: 2.84-71.43), and detachment of o-ring bands on follow-up endoscopy (OR: 8.06, 95% CI: 2.55-25.64) were independent predictive factors of EVL-induced ulcer bleeding. Various endoscopic modalities were attempted for hemostasis (EVL in 8 cases [24.2%], endoscopic variceal obturation [EVO] with cyanoacrylate in 6 cases [18.2%], argon plasma coagulation [APC] in 1 case (3%), Sengstaken-Blakemore (SB) tube in 3 cases [9.1%]), and proton pump inhibitor therapy only in 15 cases (45.5%).MELD score >10, concomitant GV F3, and detachment of o-ring bands on follow-up endoscopy are risk factors for EVL-induced ulcer bleeding.

    The aim of this study is to address the outcomes of endoscopic resection compared with surgery in the treatment of ampullary adenomas. A systematic review and meta-analysis were performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. For this purpose, the Medline, Embase, Cochrane, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Scopus and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases were scanned. Studies included patients with ampullary adenomas and data considering endoscopic treatment compared with surgery. The entire analysis was based on a fixed-effects model. Five retrospective cohort studies were selected (466 patients). All five studies (466 patients) had complete primary resection data available and showed a difference that favored surgical treatment (risk difference [RD] = -0.24, 95% confidence interval [CI] = -0.44 to -0.04). Primary success data were identified in all five studies as well. Analysis showed that the surgical approach outperformed endoscopic treatment for this outcome (RD = -0.37, 95% CI = -0.50 to -0.24). Recurrence data were found in all studies (466 patients), with a benefit indicated for surgical treatment (RD = 0.10, 95% CI = -0.01 to 0.19). Three studies (252 patients) presented complication data, but analysis showed no difference between the approaches for this parameter (RD = -0.15, 95% CI = -0.53 to 0.23). Considering complete primary resection, primary success and recurrence outcomes, the surgical approach achieves significantly better results. Regarding complication data, this systematic review concludes that rates are not significantly different. PMID:26872081

    Full Text Available BACKGROUND: Posterior urethral valves (PUV may cause subtle to severe obstruction of the urethra, resulting in a broad clinical spectrum. PUV are the most common cause of chronic renal disease in boys. Our purpose was to report the incidences of kidney and bladder dysfunction in boys treated with endoscopic valve resection for PUV. METHODOLOGY: We searched MEDLINE and EMBASE databases until 1st of July 2011, to identify original papers that described outcome of endoscopic valve resection (EVR in boys. We extracted information on (1 patient characteristics and clinical presentation of PUV related to outcomes and (2 the post-treatment absolute risks for kidney and bladder dysfunction. PRINCIPAL FINDINGS: Thirty-four studies describing renal function, vesicoureteral reflux (VUR, incontinence, and urodynamic bladder function after EVR in 1474 patients were retrieved. Patients treated for PUV show high percentages of chronic kidney disease (CKD or end stage renal disease (ESRD, 22% (0-32% and 11% (0-20%, respectively. Elevated nadir serum creatinine was the only independent factor associated with renal failure. Before treatment, VUR was present in 43% of boys and after EVR, VUR was present in 22%. Post treatment, 19% (0-70% was reported to suffer from urinary incontinence. Urodynamic bladder dysfunction was seen in many patients (55%, 0-72% after treatment of PUV. CONCLUSIONS: The reported cumulative incidence of renal and bladder dysfunction in patients with PUV after endoscopic PUV treatment varies widely. This may reflect a broad clinical spectrum, which relates to the lack of a standardised quantification of obstruction and its severity. Moreover, the risk of bias is rather high, and therefore we put little confidence in the reported estimates of effect. We found elevated nadir serum creatinine as a predictor for renal dysfunction. In order to be able to predict outcomes for patients with PUV, an objective classification of severity of

    Endoscopic injection of stabilized nonanimal hyaluronic acid/dextranomer gel is an established treatment for vesicoureteral reflux in children. We performed a subgroup analysis to assess this treatment in reflux associated with bladder dysfunction. Of 308 consecutive children treated endoscopically with stabilized nonanimal hyaluronic acid/dextranomer gel for dilating vesicoureteral reflux 54 were observed retrospectively to have bladder dysfunction. Initial followup consisted of voiding cystourethrogram at 3 and 12 months after injection, with positive response defined as reflux grade 0 or I. At 7 to 12 years following treatment patient charts were checked for urinary tract infections and bladder dysfunction, and a followup survey (postal questionnaire) was administered. A positive response to therapy (cure) was observed in 45 children (83%) after 1 to 3 endoscopic treatments. Concurrently, bladder dysfunction had resolved in 32 patients (59%). After the last stabilized nonanimal hyaluronic acid/dextranomer gel implantation 45 patients (83%) were free of urinary tract infections. Questionnaire results were similar to chart based findings. Stabilized nonanimal hyaluronic acid/dextranomer gel implantation was well tolerated, with no associated complications. Endoscopic treatment with stabilized nonanimal hyaluronic acid/dextranomer gel appears to be similarly effective in patients with vesicoureteral reflux with and without bladder dysfunction. These data indicate that bladder dysfunction should not be considered a contraindication to endoscopic treatment for reflux.

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

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

    Endoscopic insufflation has been associated with marked increase in intra-abdominal pressure (IAP) and hemodynamic and respiratory changes during transgastric surgery. To investigate the hemodynamic and respiratory effects during intraperitoneal cavity exploration through 3 different natural orifice transluminal endoscopic surgery (NOTES) access locations compared with laparoscopy. Survival experiments using 40 female pigs randomized to transgastric, transcolonic, transvaginal, and laparoscopic peritoneoscopy. On-demand endoscopic insufflation of CO(2) with feedback pressure regulation was used in NOTES with a maximum pressure of 14 mm Hg. In the laparoscopy group, the IAP was maintained at 14 mm Hg. NOTES procedures were performed by an endoscopist (with the assistance of a gynecologist in the transvaginal group and a second endoscopist in the transgastric and transrectal groups) and laparoscopy by 2 surgeons. Invasive hemodynamic and respiratory data. Blood samples were drawn for gas analyses. All experiments except one in the transrectal group were completed. The IAP was significantly lower in all NOTES groups compared with the laparoscopy group. A significant increase in mean systemic arterial blood pressure was observed in the laparoscopy group at 15 and 30 minutes of intraperitoneal cavity exploration, but it remained unchanged during all NOTES procedures. An increase in airway pressures was observed at 15 and 30 minutes of peritoneoscopy in the animals undergoing laparoscopy, whereas those parameters remained unchanged in the NOTES groups. The laparoscopy group showed a significant impairment in pulmonary gas exchange (decrease in Pao(2), increase in Paco(2), and decrease in arterial pH) after 30 minutes of peritoneoscopy, whereas only a slight increase in Paco(2) was observed in the transrectal and transvaginal groups. Healthy animal model. On-demand endoscopic insufflation of CO(2) with feedback pressure regulation can minimize the risk of hemodynamic and

    Full Text Available Diverticular disease is the most frequent cause of lower gastrointestinal bleeding. Most of the times, bleeding stops without any intervention but in 10-20 % of the cases it is necessary to treat the hemorrhage. Several modalities of endoscopic treatment have been described after purging the colon. We present five cases of severe diverticular bleeding treated with injection of epinephrine and hemoclips. All the colonoscopies were performed without purging of the colon in an emergency setting, with correct visualization of the point of bleeding. Patients recovered well avoiding other aggressive procedures such as angiography or surgery.

    Full Text Available The most common craniosynostosis, scaphocephaly, is the consequence of premature closure of the sagittal suture. Craniosynostosis does not just pose a cosmetic problem, but it can also lead to the permanent neurological deficits. Therefore early diagnosis and treatment are crucial for good outcome. Open surgery with large skin incision is currently the standard procedure. We present our first endoscope-assisted surgical procedure for scaphocephaly. The infant did not need transfusion or intensive therapy after the surgery and skin incision was minimal. This minimal invasive, new surgical technique and its development were described.

    Operative treatment for septic pre-patellar bursitis generally involves open debridement in addition to an extended course of intravenous antibiotics. Skin necrosis and wound breakdown are potential complications of this procedure in addition to scar sensitivity and a prolonged recovery. We report endoscopic bursectomy for the treatment of septic pre-patellar bursitis in eight patients over a 3-year period. All patients had microbiological confirmation of an infective process. The average age was 36 years (23-68 years). The average hospital stay was 6 days (4-9 days). No patient had a recurrence or complained of tenderness or hypoaesthesia around their wound. No patient experienced wound complications or skin necrosis. The average return to work time was 18 days (7-22 days). We conclude that endoscopic bursectomy is a safe and effective treatment for septic pre-patellar bursitis with a shortened hospital stay and a quicker return to work than conventional open debridement.

    Full Text Available Abstract Background There have been no reports discussing which imaging procedures are truly necessary before treatment of endoscopically-diagnosed early gastric cancer (eEGC. The aim of this pilot study was to show which imaging examinations are essential to select indicated treatment or appropriate strategy in patients with eEGC. Methods In 140 consecutive patients (95 men, 45 women; age, 66.4 +/- 11.3 years [mean +/- standard deviation], range, 33-90 with eEGC which were diagnosed during two years, the pre-treatment results of ultrasonography (US and contrast-enhanced computed tomography (CT of the abdomen, barium enema (BE and chest radiography (CR were retrospectively reviewed. Useful findings that might affect indication or strategy were evaluated. Results US demonstrated useful findings in 13 of 140 patients (9.3%: biliary tract stones (n = 11 and other malignant tumors (n = 2. Only one useful finding was demonstrated on CT (pancreatic intraductal papillary mucinous tumor but not on US (0.7%; 95% confidential interval [CI], 2.1%. BE demonstrated colorectal carcinomas in six patients and polyps in 10 patients, altering treatment strategy (11.4%; 95%CI, 6.1-16.7%. Of these, only two colorectal carcinomas were detected on CT. CR showed three relevant findings (2.1%: pulmonary carcinoma (n = 1 and cardiomegaly (n = 2. Seventy-nine patients (56% were treated surgically and 56 patients were treated by endoscopic intervention. The remaining five patients received no treatment due to various reasons. Conclusions US, BE and CR may be essential as pre-treatment imaging examinations because they occasionally detect findings which affect treatment indication and strategy, although abdominal contrast-enhanced CT rarely provide additional information.

    There is scarcity of data concerning the management of bleeding junctional gastroesophageal varices. Our aim was to compare the efficacy and safety of endoscopic variceal ligation (EVL) with cyanoacrylate injection for the treatment of bleeding junctional varices. One hundred fifty patients with bleeding junctional varices were included in the study. Patients were subjected after randomization to either EVL of junctional varices (group 1:75 patients) or cyanoacrylate injection (group 11:75 patients). Endoscopic sessions were continued till obliteration of the varices. Clinical as well as biochemical parameters and severity of liver disease were assessed in all patients. Control of active variceal bleeding was achieved in 61 patients (81%) in group I and in 68 patients (91%) in group II with no significant difference (p = 0.07). Re-bleeding was seen in 12 patients (16%) in group I and 5 patients in group II (6%). Junctional varix obliteration was achieved after one session in 33% of patients in group I and 52% of patients in group II, however after 2 sessions it was achieved in 67% in group I and 93 % in group II. After 3 sessions variceal obliteration was achieved in 99% in group 1. Fever, chest pain and dysphagia were observed more frequently in group II than in group I. Long term complications including spontaneous bacterial peritonitis, hepatic encephalopathy and hepatorenal syndrome were also observed more frequently group II than in group I. EVL may be a good alternative to cyanoacrylate injection in treatment of bleeding junctional varices.

    The aim was to study prospectively primary endoscopic treatment of CBD stones and further the long-term need for renewed gallstone disease interventions, defined as short- and long-term outcome. Seven years prospective follow-up of 101 consecutive patients with CBD stones who underwent endoscopic treatment with the intent of primarily achieving duct clearance. Many patients underwent several endoscopy sessions before stone clearance was completed in 83%. Eleven patients were treated surgically, 2 patients received a permanent stent, and the remaining 3 became stone free with other means. Complications occurred in 47 patients. During follow-up, 31 patients were readmitted for gallstone disease and 15 of these had recurrent CBD stones. Ten percent (8/78) of patients with the gallbladder in situ had acute cholecystitis during follow-up and late cholecystectomy was carried out in 22%. Risk factors for new gallstone disease were an in situ gallbladder containing stones and previous episodes of CBD stones. A goal of complete CBD stone clearance with ERC and ES proved to be relatively resource consuming. Subsequent cholecystectomy after duct clearance for CBD should be advised when the gallbladder lodges gallstones, especially in younger patients. Recurrent CBD stones were not influenced by cholecystectomy.

    Full Text Available

    Background and Objective

    Balloon dilatation of stricture is one of the new treatment methods for patients with Gastric Outlet Obstruction (GOO. Prevalence and underlying etiologies of GOO in various populations are different. The goal of the present study was to determine the effectiveness of endoscopic balloon dilatation and factors that could affect method advantage among patients with benign etiology for GOO.

     

    Methods

     Forty-five patients with symptoms of benign GOO were randomly selected. The mean age of patients was 43.7±18.1 years and 86.7% of them were men. Gastric outlet was delineated using double channel videoendoscopy. The severity of gastric pain was measured by VAS test immediately before and one month after balloon dilatation. Patients were followed after procedure weekly (for the first month and then monthly. Balloon dilatation was repeated for 27% patients during the follow up period.

     

    Results

    Patients were followed for 9.9±5.8 months. Furthermore, 71.1% were H. pylori positive. Positive response percent to endoscopic balloon dilatation was 80% and eight patients were took under surgical resection. Weight loss was seen frequently in the non-respondent group. The pain severity was significantly reduced in respondent subjects. No meaningful correlations were found between the response to balloon dilatation and positive H. pylori and cigarette smoking.

     

    Conclusion

    Endoscopic balloon dilatation is a safe and effective method for treating most of patients with benign gastric outlet obstruction and has favorable long-term outcome.

    Though transforaminal endoscopic discectomy has achieved a satisfactory clinical outcome in the treatment of paracentral disc herniation, it has a high failure rate for treating central disc herniation. To explore the surgical techniques of transforaminal endoscopic discectomy in treating central disc herniation and the clinical outcome based on 2-year follow-up. A retrospective study. The Department of Spinal Surgery at the Third Hospital of Hebei Medical University in China. Sixty-nine consecutive patients (male:female = 14:9, mean age 38.8 ± 10.5 years) were enrolled in the study, all of whom underwent transforaminal endoscopic discectomy due to central disc herniation. The rod adjustment technique, apex technique, and posterior longitudinal ligament detection technique were adopted for intraoperative individualization. All of the patients were followed up for 24 months to assess the visual analog scale (VAS), Japanese Orthopaedic Association (JOA), and Oswestry Disability Index (ODI) scores. The postoperative segmental instability and recurrence were observed during the follow-up period as well. MacNab criteria scores were recorded both intraoperatively and at the final follow-up; postoperative complications and the surgical outcome and safety were also evaluated. The herniated disc tissues were successfully removed for all patients, without revision by open surgery. Twenty-one cases (30.43%) were rated excellent, 44 (63.77%) good, 4 (5.80%) fair, and 0 (0.00%) poor upon the final follow-up, with an overall excellent-to-good rate of 86.96%. The VAS scores of low back and leg pain were all significantly lower at 3, 6, 12, and 24 months postoperatively compared to preoperatively (all P disc herniations. Intraoperative individualized application of rod adjustment technique, apex technique, or posterior longitudinal ligament detection technique is the key to satisfactory clinical outcome.

    Superparamagnetic iron oxide nanoparticles (SPION) may be used for local tumor treatment by coupling them to a drug and accumulating them locally with magnetic field traps, that is, a combination of permanent magnets and coils. Thereafter, an alternating magnetic field generates heat which may be used to release the thermosensitively bound drug and for hyperthermia. Until today, only superficial tumors can be treated with this method. Our aim was to transfer this method into an endoscopic setting to also reach the majority of tumors located inside the body. To find the ideal endoscopic magnetic field trap, which accumulates the most SPION, we first developed a biophysical model considering anatomical as well as physical conditions. Entities of choice were esophageal and prostate cancer. The magnetic susceptibilities of different porcine and rat tissues were measured with a superconducting quantum interference device. All tissues showed diamagnetic behavior. The evaluation of clinical data (computed tomography scan, endosonography, surgical reports, pathological evaluation) of patients gave insight into the topographical relationship between the tumor and its surroundings. Both were used to establish the biophysical model of the tumors and their surroundings, closely mirroring the clinical situation, in which we could virtually design, place and evaluate different electromagnetic coil configurations to find optimized magnetic field traps for each tumor entity. By simulation, we could show that the efficiency of the magnetic field traps can be enhanced by 38-fold for prostate and 8-fold for esophageal cancer. Therefore, our approach of endoscopic targeting is an improvement of the magnetic drug-targeting setups for SPION tumor therapy as it holds the possibility of reaching tumors inside the body in a minimal-invasive way. Future animal experiments must prove these findings in vivo.

    Most surgeons have rapidly accepted the use of minimally invasive surgical approaches for the treatment of primary hyperparathyroidism. The role of the endoscope in neck surgery is still being discussed due to its technical difficulty and complex patient selection criteria. A prospective study was conducted between April 2010 and April 2013. It included patients diagnosed with sporadic primary hyperparathyroidism (sPHPT) by locating a single adenoma using ultrasound and sestamibi scintigraphy imaging. All patients agreed to be included in the study. Experienced endocrine surgeons that had been trained in endocrine minimally invasive surgery performed the procedure. The same surgical technique was used in all of the cases. The demographic and clinical variables were evaluated. A descriptive analysis was performed on the data measuring mean, standard deviation, and range. A total of 28 endoscopic lateral parathyroidectomies were performed. All patients were diagnosed with sporadic hyperparathyroidism sPHPT. The mean age was 68 years (59-89). No intraoperative complications were registered. Postoperative morbidity was comparable to that reported in the classical approach. A favourable outcome was observed in 27 of the 28 patients (96%) after a mean follow-up time of 22 (9 - 53) months. An endoscopic approach for hyperparathyroidism sPHPT is feasible and reproducible, and it obtains comparable results to the classical open surgery. Several factors make this technique suitable for highly specialised hospitals with a high patient volume and specialised endocrine surgery units. Copyright © 2015 Academia Mexicana de Cirugía A.C.

    Full Text Available Endoscopic injection treatment for VUR appears to have less success rate than open surgical treatment, even in Gr 3 VUR. Economics of use of deflux injection and its success rate do not suit Indian milieu. To achieve high success rate of Atlanta group in endoscopic injection treatmnent , requires a longer learning curve and yet it has not achieved success rate of 96-98% achieved by open surgical techniques. Recent addition of modified extravesical reimplantation technique has reduced significantly the post operative pain and patient can be discharged within 2 days from the hospital.

    Orbital apex syndrome (OAS) is a complex disease caused by a variety of pathological factors, and trauma is one of the main factors/causes. Clinical data of 17 cases of traumatic OAS treated by nasal endoscopic surgery in our department from January 2002 to April 2009 were gathered and reviewed. Among them, the six patients presented with OAS after injury to the lateral wall of orbital apex. Seven other patients exhibited OAS after injury to the medial wall of orbital apex, two displayed OAS after zygomatic trauma, while OAS manifested in the other two patients with craniocerebral trauma 3 days after they had decompressive craniotomy--of them, one was blind in both eyes. In the 17 cases, 6 patients were without light sensation, 1 was blind in both eyes; the sight-chart index of eight patients was 0.1, that of three other patients was 0.1-0.2. Fifteen patients displayed eyeball movement disturbance (disorder) and cornea sensory disturbance (disorder), two were with the eyeball abducent disturbance. After the nasal endoscopic surgeries for OAS performed on the 17, the sight of the most patients was restored in varying degrees. The sight of nine patients was between 0.2 and 0.3, that of two patients was between 0.1 and 0.2, that of the other two patients was 0.1, and that of four patients remained unchanged. The eyeball movement and the cornea esthesia in 15 patients recovered from the surgeries, one patient recovered with good eyeball adducent movement and the cornea esthesia but with eyeball abducent disturbance, the other patient did not make a recovery from the eyeball immobility, cornea anesthesia and ptosis. A follow-up lasting 2 months to 2 years suggested that the 16 patients had stable recovery from the surgeries. Satisfactory results could be achieved in the treatment of traumatic OAS by nasal endoscopic surgery. From objective assessment of the therapeutic effects of traumatic OAS, it can be concluded that if a patient is diagnosed with fractures of the

    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.

    Heterotopic gastric mucosa patches are congenital gastrointestinal abnormalities and have been reported to occur anywhere along the gastrointestinal tract from mouth to anus. Complications of heterotopic gastric mucosa include dysphagia, upper gastrointestinal bleeding, upper esophageal ring stricture, adenocarcinoma and fistula formation. In this case report we describe the diagnosis and treatment of the first case of esophago-bronchial fistula due to heterotopic gastric mucosa in mid esophagus. A 40-year old former professional soccer player was referred to our department for treatment of an esophago-bronchial fistula. Microscopic examination of the biopsies taken from the esophageal fistula revealed the presence of gastric heterotopic mucosa. We decided to do a non-surgical therapeutic endoscopic procedure. A sclerotherapy catheter was inserted through which 1 mL of ready to use synthetic surgical glue was applied in the fistula and it closed the fistula opening with excellent results.

    Bezoars result from accumulation of indigestible materials in the gastrointestinal tract and often occur in the stomach. In this study, we evaluated the use of guidewires in patients with gastric phytobezoars (PBs) as a new method for PB removal and examined the safety of the procedure. Between February 2009 and January 2013, we analyzed data from 11 patients with gastric PBs. We fitted a transparent cap to a standard endoscope (EG450WR5, Fujinon), and a 0.025 inch guidewire was passed through the standart endoscope. PBs were surrounded by a loop in the guidewire and destroyed. After 2 weeks of treatment, patients were re-evaluated for effectiveness. PB fragmentation time was 5-11 minutes. In five patients with a history of gastric surgery, we needed an additional 16-28 minutes for removal of the fragments. In six patients additionally treated with enzymatic degradation after the breaking procedure, PBs completely disappeared within 2 weeks. There were no complications during the procedure. The guidewire and fragmentation procedure for PBs is an efficient and reliable method. When combined with enzymatic degradation, PBs can be managed quickly and effectively.

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

    Aim of this study is to examine the effectiveness of dextranomer/hyaluronic acid copolymer and polyacrylate polyalcohol copolymer in endoscopic treatment of vesicoureteral reflux disease in adult patients with and without chronic renal failure. Thirty two patients (12 female, 20 male) with a total of 50 renal units were treated for vesicoureteral reflux. There were 26 (81%) chronic renal failure patients. The success of treatment was evaluated by voiding cystouretrography at 3rd and 12th months after subureteric injection. The persistence of reflux was considered as failure. Patients were divided into two groups according to injected material. Age, sex, grade of reflux and treatment results were recorded and evaluated. Reflux was scored as grade 1 in seven (14%), grade 2 in 16 (32%), grade 3 in 21 (42%) and grade 4 in six (12%) renal units. There was not patient with grade 5 reflux. Fourteen renal units (28%) were treated with dextranomer/hyaluronic acid copolymer (group 1) and 36 renal units (72%) were treated with polyacrylate polyalcohol copolymer (group 2). The overall treatment success was achieved at 40 renal units (80%). The treatment was successful at 11 renal units (79%) in group 1 and 29 renal units (81%) in group 2 (p = 0.71). There was not statistically significant difference between two groups with patients with chronic renal failure in terms of treatment success (p = 1.00). The effectiveness of two bulking agents was similar in treatment of vesicoureteral reflux disease in adult patients and patients with chronic renal failure.

    Pancreaticojejunostomy stricture (PJS) is a late complication of pancreaticoduodenectomy. The endoscopic treatment of PJS is very challenging due to the difficulty of locating the small anastomotic site and passing the stricture using a guidewire. We herein report two cases of severe PJS. These patients could not be treated using only double-balloon endoscopy or endoscopic ultrasound-guided puncture of the main pancreatic duct because of severe stenosis at the anastomotic site. However, we could treat them by the rendezvous technique using the rigid part of the guidewire to penetrate PJS. This method was useful and safe for treating severe PJS. PMID:29151507

    BACKGROUNDS AND STUDY AIMS: Effect of endoscopic variceal ligation (EVL) on gastric mucosal hemodynamics would differ in patients with and without large fundal varices. The aim of this study was to test this hypothesis. Twenty-seven patients with cirrhosis and large sized esophageal varices were prospectively studied. There were eight patients with large fundal varices and 19 patients without large fundal varices. Before EVL, gastric mucosal hemodynamics were endoscopically assessed by laser-Doppler velocimetry and reflectance spectrophotometry in the antrum and the corpus. In the reflectance spectrophotometric measurements, gastric mucosal hemoglobin content (IHb) and gastric mucosal oxygen saturation (ISO2) were determined. The severity of portal-hypertensive gastropathy (PHG) was also recorded at the antrum and the corpus. For data analysis, PHG was scored (absent, 0; mild, 1; severe, 2; bleeding, 3). These measurements were repeated after initial (three days after initial session) and repeated (seven days after last session) EVL. At the antrum, neither PHG score nor gastric mucosal hemodynamic parameters were modified after initial and repeated EVL in patients with and without large fundal varices. In addition, no significant differences of the integrated changes in PHG score and gastric mucosal hemodynamic parameters were observed in the two groups. At the corpus, PHG score significantly increased after initial and repeated EVL in patients without large fundal varices. In these patients, laser-Doppler signal and ISO2 significantly decreased and IHb significantly increased after initial and repeated EVL. In contrast, PHG score, laser-Doppler signal, and ISO2 did not change significantly in patients with large fundal varices, although IHb transiently increased after initial EVL. Furthermore, the integrated changes in PHG score and gastric mucosal hemodynamic parameters were significantly lower in patients with large fundal varices than in those without. The

    Full Text Available Background Proton-pump inhibitors have been used for at least two decades. They are among the most commonly sold drugs in the world. However, some controversy remains about the indications for their use and the consequences of their prolonged use. Objectives To evaluate and compare the endoscopic and histopathologic gastric changes in chronic users of proton-pump inhibitors to changes in non-users. Methods A prospective study performed at a tertiary Public Hospital involving 105 patients undergoing upper-gastrointestinal endoscopy. Subjects included 81 proton-pump inhibitor users and 24 non-users (control group. Biopsies of the antral-type mucosa, the antral-fundic transition, and the fundus were evaluated by the Sydney System. The presence of erosion or ulceration, lymphatic follicles, reactive gastropathy, and polypoid or epithelial hyperplasia was also determined. Serum levels of gastrin were measured. Results We found two polyps, one in each group, both of which were negative for Helicobacter pylori. There were two cases of parietal cell hyperplasia in users of proton-pump inhibitors. Gastrin was elevated in 28 users of proton-pump inhibitors and in four members of the control group. We did not find statistically significant differences in the endoscopic or histopathologic findings between the two groups. Conclusions Chronic use of proton-pump inhibitors for the duration examined was not associated with significant gastric changes. An interesting finding was that the 4 chronic users of proton-pump inhibitors who had serum gastrin levels above 500 pg/mL also had positive serology for Chagas disease.

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

    Full Text Available Background: Kartagener syndrome (KS is a rare congenital disease characterised by a clinical triad of symptoms: situs inversus, chronic rhinosinusitis, and bronchiectasis. Although congenital ciliary defect is recognised as the main cause of this syndrome, it remains difficult to treat the associated airway infection. Case Report: A 17-year-old female patient presented with repeated refractory airway infection. She also had bronchiectasis and situs inversus. Electron microscopic evaluation of her nasal mucosa revealed ciliary defect and confirmed the diagnosis of KS. She underwent functional endoscopic sinus surgery (FESS followed by long-term postoperative debridement of the sinonasal cavity. This treatment reduced chronic rhinosinusitis and protected against subsequent airway infection in a 7-year follow-up. Conclusion: FESS is effective for relieving both chronic rhinosinusitis and lung infection of KS in the long term.

    Radiation-crosslinked poly(vinyl pyrrolidone) (PVP)-Chitosan was prepared as a potential injectable implant for endoscopic treatment of vesicoureteral reflux (VUR). The physical and histological properties of PVP-Chitosan implant in comparison with the commercial dextranomer/hyaluronic acid copolymer (Deflux) have been evaluated in vivo by subcutaneous and abdominal injection in rats over a period of 6 months. The PVP-Chitosan implant was easily injected through 26-gauge needle. Monthly gross examination of the implanted sites showed no significant decrease in volume of implant and no local inflammatory reaction. Histological findings indicated no evidence of migration to the distant organs after 6 months of implantation. Results of this study indicated that PVP-Chitosan implant has properties of a good tissue augmenting substance such as stability, biocompatibility and non-migration but long-term studies are needed to evaluate its therapeutic efficiency.

    The development of minimally invasive techniques allowed access to the necrotic cavity through transperitoneal, retroperitoneal, transmural and transpapillary routes. The choice of access to walled-off pancreatic necrosis (WOPN) should depend not only on the spread of necrosis, but also on the experience of the clinical center. Herein we describe treatment of a patient with multilocular symptomatic walled-off pancreatic necrosis using minimally invasive techniques. The single transmural access (single transluminal gateway technique - SGT) to the necrotic collection of the patient was ineffective. The second gastrocystostomy was performed using the same minimally invasive technique as an extra way of access to the necrosis (multiple transluminal gateway technique - MTGT). In the described case the performance of the new technique consisting in endoscopic multiplexing transmural access (MTGT) was effective enough and led to complete recovery of the patient.

    Full Text Available OBJECTIVE: Blake's pouch cyst (BPC is a midline cystic malformation of the posterior fossa, within Dandy-Walker's complex (DWC, often associated with hydrocephalus. Endoscopic third ventriculostomy (ETV has been an alternative to conventional methods for BPC treatment. This study aimed at reporting our experience with ETV in a series of patients with BPC. METHODS: Of 33 patients diagnosed with midline posterior fossa cyst, 26 met the protocol criteria for DWC, and eight subjects with BPC were selected (aged one month to two years old. All cases were treated with ETV. RESULTS: Five patients were male; and three were prenatally diagnosed. They had hydrocephalus and motor deficiencies. Motor assessment at a five-year follow-up yielded normal findings. All patients improved, and only one had residual cognitive dysfunction, despite overall neurological improvement. There were no complications. CONCLUSIONS: ETV was a safe and effective procedure, reducing risks and morbidity associated with open surgery and shunt-related problems.

    There are few data regarding endoscopic retrograde cholangiopancreatography (ERCP) usefulness in children and adolescents. We reviewed the long-term experience with diagnostic and therapeutic ERCP in a tertiary single center in Southern Brazil. A retrospective chart review of patients aged 0-18 years who had undergone ERCPs from January 2000 to June 2012 was done. Data on demographics, indications, diagnosis, treatments, and complications were collected. Seventy-five ERCPs were performed in 60 patients. The median age of the patients at the procedure was 13.9 years (range: 1.2-17.9). Of the 60 patients, 47 (78.3%) were girls. Of all ERCPs, 48 (64.0%) were performed in patients above 10 years and 35 (72.9%) of them were in girls. ERCP was indicated for patients with bile duct obstruction (49.3%), sclerosing cholangitis (18.7%), post-surgery complication (12%), biliary stent (10.7%), choledochal cyst (5.3%), and pancreatitis (4%). The complication rate of ERCP was 9.7% involving mild bleeding, pancreatitis and cholangitis. Patients who had therapeutic procedures were older (13.7±3.9 vs. 9.9±4.9 years; P=0.001) and had more extrahepatic biliary abnormalities (82% vs. 50%; P=0.015) than those who had diagnostic ERCPs. A marked change in the indications of ERCPs was found, i.e., from 2001 to 2004, indications were more diagnostic and from 2005 therapeutic procedures were predominant. Diagnostic ERCPs are being replaced by magnetic resonance cholangiopancreatography and also by endoscopic ultrasound. All these procedures are complementary and ERCP still has a role for therapeutic purposes.

    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.

    Background and study aims: Overall, 5 % to 15 % of patients undergoing cholecystectomy for cholelithiasis have concomitant bile duct stones, and the incidence of choledocholithiasis increases with age. There is no clear consensus on the best therapeutic approach (endoscopic versus surgical). Patients and methods: A prospective randomized controlled clinical trial was performed to compare three treatment options for patients with choledocholithiasis at the National Center for Minimally Invasive Surgery in Havana, Cuba from November 2007 to November 2011. The patients were randomized in three groups. Group I: patients who underwent intraoperative cholangiography (IOC) to confirm the choledocholithiasis followed by laparoscopic cholecystectomy (LC) associated with intraoperative endoscopic retrograde cholangiopancreatography (ERCP), group II: patients who underwent preoperative ERCP followed by LC during the same hospital admission and group III: patients who underwent IOC to confirm the choledocholithiasis followed by LC associated with laparoscopic common bile duct exploration (LCBDE). Results: A total of 300 patients with suspected choledocholithiasis were included in the trial and were randomized. As a result, a total of 134 patients were diagnosed with the presence of choledocholithiasis and treated during the study period. There were no significant differences in success rates of ductal stone clearance, but retained stone, postoperative complications and length of hospital stay were better in group I. Conclusions: Intraoperative ERCP/ES shows a higher rate of common bile duct stones clearance, a shorter hospital stay, and lower morbidity, but further research with a larger study population is necessary to determine the additional benefits of this procedure. The results to date suggests that in appropriate patients, single-stage treatments are the best options. PMID:27857966

    Fecal incontinence (FI) is a major part of illness and physical discomfort in the general population. Since the 1990s, sacral nerve stimulation has been well established in the treatment of neurogenic FI. The precise placement of the electrode is crucial for the success of the procedure. Eighty percent of the patients benefit from permanent treatment, but in 10-20% of the patients tested electrode placement proves impossible due to anatomical variations of the sacral foramina. In this study, we describe the technical requirements and a new method of electrode placement with reference to the anatomical (bone) landmarks in an animal model. With a small endoscope (Verres needle), we accessed the perirectal space to identify the nervous structures. A stimulated sphincter EMG was obtained for the experimental animals and muscle action potential (MAP/M-wave), latency time [ms], and the amplitude of the motor response [μV] were recorded. Electrodes were placed, the animals killed and dissected leaving the pelvic cavity untouched. The specimens were examined in a magnetic resonance scanner and in a multi-slice computed tomography scanner to detect the electrode material and possible surgical complications. After that the specimens were dissected. In all eight cases in the four animals tested, we were able to stimulate the sacral nerve as demonstrated by the EMG findings. No major surgical complications were observed for the procedure. Endoscopic sacral nerve root stimulation is a safe and effective method for delivering stimulation material in the pelvis of the sheep. It is a promising procedure to be tested in humans. © 2010 Blackwell Publishing Ltd.

    Full Text Available Introduction: Obstructive airway pathology in children may be congenital or acquired. Fortunately, it is a rare condition, but in most cases, it implies a diagnostic and therapeutic challenge. Endoscopic techniques have experienced in the last years a breakthrough in the treatment of these lesions, but open surgery still plays an important role. Objective: Our objective was to review the most frequent causes of obstruction of the central airway in the child, their diagnostic and current treatment status. Conclusions: Obstructive airway pathology in children requires immediate stabilization, detailed assessment, meticulous planning and individualized treatment. Management of patients with airway obstruction requires a close cooperation between specialists organized in multidisciplinary teams, whose main objective is the diagnosis and timely resolution of the various congenital malformations and acquired lesions that affect the larynx, trachea and bronchi. In many cases the decision of the treatment of choice is not easy. Selection of the most suitable treatment depends on the patient’s clinical situation and the anatomic type of stenosis. The surgeon must master all available techniques, to solve each specific situation.

Thereafter, an alternating magnetic field generates heat which may be used to release the thermosensitively bound drug and for hyperthermia. Until today, only superficial tumors can be treated with this method. Our aim was to transfer this method into an endoscopic setting to also reach the majority of tumors located inside the body. To find the ideal endoscopic magnetic field trap, which accumulates the most SPION, we first developed a biophysical model considering anatomical as well as physical conditions. Entities of choice were esophageal and prostate cancer. The magnetic susceptibilities of different porcine and rat tissues were measured with a superconducting quantum interference device. All tissues showed diamagnetic behavior. The evaluation of clinical data (computed tomography scan, endosonography, surgical reports, pathological evaluation of patients gave insight into the topographical relationship between the tumor and its surroundings. Both were used to establish the biophysical model of the tumors and their surroundings, closely mirroring the clinical situation, in which we could virtually design, place and evaluate different electromagnetic coil configurations to find optimized magnetic field traps for each tumor entity. By simulation, we could show that the

    Although laparoscopic Nissen fundoplication is the standard surgical treatment for gastroesophageal reflux disease (GERD), surgical complications and post-operative pain are not uncommon, especially for those patients who are neurologically impaired (NI) or undergoing re-operative procedures. To address this challenge, we utilized the transoral incisionless fundoplication (TIF) procedure to treat GERD via an endoscopic approach. Eleven TIF patients were included with an average age of 16.5 ± 5.1 years and weight of 45.7 ± 13.3 kg. NI was present in nine patients (82%), including a predominant number of patients with a history of seizures and gastrostomy tube feeding. Five patients had a history of a previous failed fundoplication requiring a re-operative procedure (45%). A retrospective chart review evaluated patient outcomes and post-operative complications. The length of the TIF procedure was 113.3 ± 31.3 min with minimal blood loss. The length of stay was 1.2 ± 0.4 days, although one TIF patient was re-admitted for endoscopic clipping for gastric bleeding. At a follow-up of 8.2 ± 4.2 months, TIF effectively resolved GERD in 10 out of 11 children. A few of the patient's families reported complaints of gagging or dysphagia (30%, 3/11); however it was difficult to determine if complaints were due the procedures itself or baseline NI. All patients who had a follow-up upper GI or pH probe study showed no evidence of reflux. One TIF patient had no recurrent reflux but required an esophago-gastric disconnection for retching. The TIF procedure can complement the current surgically and medically available options for children with GERD, especially in complicated patients such as those with NI. However, complications including hemorrhage emphasize the potential risk of the procedure. Further studies with more patients and a longer follow-up course must be conducted to better assess efficacy.

    Full Text Available ObjectiveTo investigate the effect and safety of endoscopic injection of cyanoacrylate in the treatment of esophageal and gastric variceal bleeding (EGVB in children. MethodsThe clinical data of 35 children with acute EGVB who were treated with endoscopic injection of cyanoacrylate in Children′s Hospital of Baoji Maternal and Child Health Care Hospital from August 2010 to August 2015 were analyzed retrospectively. The emergency response rate, rebleeding rate, and incidence of complications after the treatment were analyzed statistically. ResultsThirty-five patients received 46 times of endoscopic injection of cyanoacrylate in total. The response rate to the initial injection was 95.6% (44/46. The volume of cyanoacrylate injected was 0.2-0.6 ml, with a mean volume of 0.4±0.2 ml. The emergency hemostasis rate was 93.4% (43/46, the rebleeding rate was 11.4% (4/35, and the cycle for 4 patients with the recurrence of bleeding to be cured was 1.2-23.0 months (mean 121±10.9 months. One patient experienced abdominal pain, and no patients experienced ectopic embolism. Two patients died after injection. ConclusionFrequent, small-volume endoscopic injection of cyanoacrylate is an effective and convenient therapeutic method for EGVB in children, has few complications, and holds promise for clinical application.

    Background Among the various methods of combined endoscopic therapy for high-risk bleeding peptic ulcers the use of adrenaline followed by injection of ethanolamine is minimally demanding in terms of the endoscopic skills and instrumentation but has not been adequately studied. The aim of the present study is to determine whether the injection of ethanolamine in combination with epinephrine compared to injection of epinephrine alone reduces rebleeding rates, need for surgery and overall mortality of patients with bleeding ulcers. Methods Patients with ulcers and endoscopic features indicative of a high risk for spontaneous recurrent bleeding were included. High risk was defined by the Forrest classification. Patients were assigned to injection of epinephrine alone (n = 284) or epinephrine plus ethanolamine (n = 131). Results Initial hemostasis was achieved in 96% of patients in both groups. We detected significant difference in rates of recurrent bleeding, 16.4% vs. 8.7%, for epinephrine and epinephrine plus ethanolamine respectively (P<0.05). When patients were stratified according to Forrest criteria, no significant difference could be found, although there was a trend towards less recurrent bleeding in the case of dual injection therapy in all patient subgroups. There was no significant difference in the proportions of patients who required surgery, 7.7% vs. 7.6% respectively. Mortality was equal (3.2 vs. 3.1%) in the two groups. No major complications from endoscopic treatment were observed in either group. Conclusion Adding ethanolamine to epinephrine for injection treatment of bleeding peptic ulcers decreases bleeding recurrence rates and represents a safe endoscopic treatment for high-risk bleeding ulcers.

    In the post-ESWL period, ureteroscopy represented the solution giving a second choice in the treatment of ureteral calculi in case of failure of extracorporeal lithotripsy. The aim of this study is to review a wide series of ureteral stones in which ureteroscopy combined with endoscopic lithotripsy can be chosen as the first approach for the treatment of ureteral calculi. Between January 1994 and September 1997, 378 patients underwent ureteroscopy and endoscopic lithotripsy for ureteral stones with a miniscope associated with either a pneumatic or electropneumatic lithotriptor. Three different miniscopes were used: Olympus (8 Fr), Wolf (7 Fr) and Circon Acmi (7.7 Fr). 238 patients were male and 140 were female. The stones were localized in the upper tract of the ureter in 62 cases (16.4%), 96 (25.3%) in the mid ureter and 220 (58. 3%) in the lower ureter. A complete stone fragmentation with spontaneous expulsion of the fragments occurred in 354 patients (93.6%). In 22 patients (5.8%) the stones were accidentally pushed up and successfully underwent ESWL. In 38 patients (10%) the fragments were completely removed by basket. A single J polyethylene catheter was placed in 21 (5.5%) and a JJ stent in 147 patients (38. 8%). The operative time ranged from 10 to 60 min, with an average time span of 32. In 22 cases (5.8%) an iterative ureteroscopy for stenosis or incomplete fragmentation was needed. Five cases (1.3%) of ureteral perforation were successfully treated by JJ stent, and only 1 case of ureteral avulsion (upper ureter) was treated by open surgery. In the attempt of overcoming an ureteral stenosis, we had 1 case (0.2%) of ureteral reimplantation. One patient (0.2%) underwent ureterolithotomy for an extremely narrow stenosis just before the ureteropelvic junction. No relevant complication was recorded in the postoperative period. Patients were dismissed after 1- 4 days (average 1.9). Up until now, no case of postoperative ureteral stricture has been observed

    Achalasia is a rare motility disorder of the esophagus. Treatment is palliative with the goal of symptom remission and slowing the progression of the disease. Treatment options include per oral endoscopic myotomy (POEM), laparoscopic Heller myotomy (LM) and endoscopic treatments such as pneumatic dilation (PD) and botulinum toxin type A injections (BI). We evaluate the economics and cost-effectiveness of treating achalasia. We performed cost analysis for POEM, LM, PD and BI at our institution from 2011 to 2015. Cost of LM was set to 1, and other procedures are presented as percentage change. Cost-effectiveness was calculated based on cost, number of interventions required for optimal results for dilations and injections and efficacy reported in the current literature. Incremental cost-effectiveness ratio was calculated by a cost-utility analysis using quality-adjusted life year gained, defined as a symptom-free year in a patient with achalasia. Average number of interventions required was 2.3 dilations or two injections for efficacies of 80 and 61 %, respectively. POEM cost 1.058 times the cost of LM, and PD and BI cost 0.559 and 0.448 times the cost of LM. Annual cost per cure over a period of 4 years for POEM, and LM were consistently equivalent, trending the same as PD although this has a lower initial cost. The cost per cure of BI remains stable over 3 years and then doubles. The cost-effectiveness of POEM and LM is equivalent. Myotomy, either surgical or endoscopic, is more cost-effective than BI due to high failure rates of the economical intervention. When treatment is being considered BI should be utilized in patients with less than 2-year life expectancy. Pneumatic dilations are cost-effective and are an acceptable approach to treatment of achalasia, although myotomy has a lower relapse rate and is cost-effective compared to PD after 2 years.

    Full Text Available Purpose Aim of this study is to examine the effectiveness of dextranomer/hyaluronic acid copolymer and polyacrylate polyalcohol copolymer in endoscopic treatment of vesicoureteral reflux disease in adult patients with and without chronic renal failure. Materials and Methods Thirty two patients (12 female, 20 male with a total of 50 renal units were treated for vesicoureteral reflux. There were 26 (81% chronic renal failure patients. The success of treatment was evaluated by voiding cystouretrography at 3rd and 12th months after subureteric injection. The persistence of reflux was considered as failure. Patients were divided into two groups according to injected material. Age, sex, grade of reflux and treatment results were recorded and evaluated. Results Reflux was scored as grade 1 in seven (14%, grade 2 in 16 (32%, grade 3 in 21 (42% and grade 4 in six (12% renal units. There was not patient with grade 5 reflux. Fourteen renal units (28% were treated with dextranomer/hyaluronic acid copolymer (group 1 and 36 renal units (72% were treated with polyacrylate polyalcohol copolymer (group 2. The overall treatment success was achieved at 40 renal units (80%. The treatment was successful at 11 renal units (79% in group 1 and 29 renal units (81% in group 2 (p = 0.71. There was not statistically significant difference between two groups with patients with chronic renal failure in terms of treatment success (p = 1.00. Conclusions The effectiveness of two bulking agents was similar in treatment of vesicoureteral reflux disease in adult patients and patients with chronic renal failure.

    Full Text Available Aim: We aimed to compare the success rate of the use of a pneumatic and a holmium laser lithotripter for endoscopic treatment of upper ureteral calculi with semirigid uretero-renoscopy (URS. Material and Method: A total of 74 patients were included in this study. The patients were divided into two groups; a ballistic lithotripter was used for group 1 containing 33 and a Holmium-YAG laser lithotripter for the remaining 41 patients in group 2. Both groups were compared in terms of stone size the duration of the operation, postoperative hospitalization time, stone-free rate and complications. Results: The mean age of the patients was 47.6. The mean stone size in groups 1 and 2 were 16.4mm and 11.0mm, respectively (p=0.043. The mean stone-free rate groups 1 and 2 were 78.7% and 80.5% respectively at the approximately 1 month follow-up (p=0.391. In group 1 two patients and in group 2 two patients had a minor complication (ClavienI-II. In group 1 three patients had major complications due to ureteral perforation (Clavien 3a and 3b. No major complications (Clavien III-V occurred in Group 2. Discussion: Based on these findings laser lithotripsy can be regarded as safer. If laser lithotripter is available in medical centers, we argue that it should be the first choice for the treatment of upper ureteral stones.

    In children, endoscopic sclerotherapy and variceal ligation (EVL) are the most used techniques for the treatment of gastroesophageal variceal bleeding (VB). However, these techniques achieve poor results in cases of gastric variceal bleeding, and EVL is not applicable in young infants. Our purpose was to evaluate the feasibility, efficacy, and safety of cyanoacrylate glue injection for the treatment of gastroesophageal varices in young infants. Single-center prospective study. From 2001 to 2005, 8 young infants (data and the results were registered and analyzed at 1, 6, and 12 months after treatment. The mean age and weight were 1.3 +/- 0.42 years (range 0.8 to 1.9 years) and 8.5 +/- 1.6 kg (range 5.5 to 10 kg). Glue injection was successfully performed in all infants. The mean volume injected was 1.15 +/- 0.62 mL (range 0.5 to 2 mL). Immediate control of bleeding was achieved in all cases. Ulcer bleeding as a complication was observed in 1 case. Varices relapse with bleeding was observed in 3 of 8 (37.5%) patients after a mean of 12.5 +/- 10.6 weeks (range 5 to 20 weeks). Patients with variceal rebleeding were retreated. Varices eradication was achieved in all cases after a mean of 1.4 +/- 0.52 sessions (range 1 to 2 sessions). Open prospective series with a relatively small number of patients. In young infants, the use of cyanoacrylate glue is safe and effective for the treatment of gastroesophageal VB.

    To analyze the clinical effects of percutaneous transforaminal endoscopic technique in treating lumbar intervertebral disc herniation and sciatica. From June 2011 to January 2012,the clinical data of 46 patients with lumbar intervertebral disc herniation and sciatica underwent percutaneous transforaminal endoscopic technique were retrospectively analyzed. There were 28 males and 18 females,ranging in age from 11 to 77 years old with an average of (39.7_ 15.3) years old,20 cases were L5S1 and 26 cases were L4,5. All patients had the symptoms such as lumbago and sciatica and their straight-leg raising test were positive. Straight-leg raising test of patients were instantly repeated after operation;operative time,volume of blood loss,complication, length of stay and duration of back to work or daily life were recorded. The clinical effects were assessed according to the VAS,JOA and JOABPEQ score. All operations were successful,postoperative straight-leg raising test were all negative. Operative time,volume of blood loss,length of stay,duration of back to work or daily life,follow-up time were (93.0+/-28.0) min, (20.0+/-9.0)ml, (3.1+/-1.5) d, (11.6+/-4.2) d, (13.9+/-1.6) months,respectively.

    Full Text Available Morbid obesity is an epidemic and complex disease which imposes a multidisciplinary approach. Laparoscopic sleeve gastrectomy has become a frequent procedure given its efficacy and safety compared to other surgical options. However, it isn’t free from complications. Lax gastric fixation or incorrect positioning of the stomach during surgery can result in early gastric outlet obstruction caused by a volvulus-like mechanism by rotation of the stomach around its anatomic axes. This report refers to two cases of post sleeve gastric torsion resulting in persisting vomiting after initiating oral intake. The diagnosis was confirmed by upper gastrointestinal-contrast study and gastroscopy. In both cases, a fully covered self-expandable metallic stent was inserted which prompted the gastric lumen to become permeable resulting in symptomatic resolution. The stents were removed endoscopically after two and three months. Beyond more than three years of follow-up, the patients remain asymptomatic and no recurring “stenosis” was noticed. In these cases the use of fully covered self-expandable metallic stents demonstrated to be effective and safe in the treatment of post sleeve gastric torsion.

    Thoracic disc herniation is a relatively rare yet challenging-to-diagnose condition. Currently there is no universally accepted optimal surgical treatment for symptomatic thoracic disc herniation. Previously reported surgical approaches are often associated with high complication rates. Here we describe our minimally invasive technique of removing thoracic disc herniation, and report the primary results of a series of cases. Between January 2009 and March 2012, 13 patients with symptomatic thoracic disc herniation were treated with endoscopic thoracic foraminotomy and discectomy under local anesthesia. A bone shaver was used to undercut the facet and rib head for foraminotomy. Discectomy was achieved by using grasper, radiofrequency, and the Holmium-YAG laser. We analyzed the clinical outcomes of the patients using the visual analogue scale (VAS), MacNab classification, and Oswestry disability index (ODI). At the final follow up (mean: 17 months; range: 6–41 months), patient self-reported satisfactory rate was 76.9%. The mean VAS for mid back pain was improved from 9.1 to 4.2, and the mean ODI was improved from 61.0 to 43.8. One complication of postoperative spinal headache occurred during the surgery and the patient was successfully treated with epidural blood patch. No other complications were observed or reported during and after the surgery. PMID:24455232

    Fetal endoscopic tracheal occlusion (FETO) is a promising treatment for severe congenital diaphragmatic hernia, a condition that carries significant morbidity and mortality. It is hypothesised that balloon occlusion of the fetal trachea leads to an improvement in lung growth and development. The major documented complications of FETO to date are related to preterm delivery. To report a series of five infants who developed tracheomegaly following FETO. Review of all children referred with tracheomegaly to the paediatric intensive care and tracheal service at two referral centres. Five neonates presented with features of respiratory distress shortly after birth and were subsequently found to have marked tracheomegaly. Two neonates had tracheomalacia in addition. There are no previous reports in the literature describing tracheomalacia, or more specifically, tracheomegaly, as a consequence of FETO. We propose that the particularly compliant fetal airway is at risk of mechanical damage from in utero balloon occlusion. This observation of a new problem in this cohort suggests a thorough evaluation of the trachea should be performed in children who have had FETO in utero. It may be that balloon occlusion of the trachea earlier in utero (before 26 weeks' gestation) predisposes to this condition. (orig.)

    Full Text Available Background: Biliary cast syndrome (BCS was a postoperative complication of orthotopic liver transplantation (OLT, and the reason for BSC was considered to relate with ischemic type biliary lesions. This study aimed to evaluate the relationship between BCS following OLT and the hepatic artery resistance index (HARI, and to observe pathological changes and morphology of biliary casts. Methods: Totally, 18 patients were diagnosed with BCS by cholangiography following OLT using choledochoscope or endoscopic retrograde cholangiopancreatography. In addition, 36 patients who did not present with BCS in the corresponding period had detectable postoperative HARI on weeks 1, 2, 3 shown by color Doppler flow imaging. The compositions of biliary casts were analyzed by pathological examination and scanning electron microscopy. Results: HARI values of the BCS group were significantly decreased as compared with the non-BCS group on postoperative weeks 2 and 3 (P 1 (OR = 1.300; 1.223; and 1.889, respectively. The OR of HARI 3 was statistically significant (OR = 1.889; 95% confidence interval = 1.166-7.490; P = 0.024. The compositions of biliary casts were different when bile duct stones were present. Furthermore, vascular epithelial cells were found by pathological examination in biliary casts. Conclusions: HARI may possibly serve as an independent risk factor and early predictive factor of BCS. Components and formation of biliary casts and bile duct stones are different.

    Esophageal perforations and postoperative leakage of esophagogastrostomies are considered to be life-threatening conditions due to the potential development of mediastinitis and consecutive sepsis. Vacuum-assisted closure (VAC) techniques, a well-established treatment method for superficial infected wounds, are based on a negative pressure applied to the wound via a vacuum-sealed sponge. Endoluminal VAC (E-VAC) therapy as a treatment for GI leakages in the rectum was introduced in 2008. E-VAC therapy is a novel method, and experience regarding esophageal applications is limited. In this retrospective study, the experience of a high-volume center for upper GI surgery with E-VAC therapy in patients with leaks of the upper GI tract is summarized. To our knowledge, this series presents the largest patient cohort worldwide in a single-center study. Between October 2010 and January 2017, 77 patients with defects in the upper gastrointestinal tract were treated using the E-VAC application. Six patients had a spontaneous perforation, 12 patients an iatrogenic injury, and 59 patients a postoperative leakage in the upper gastrointestinal tract. Complete restoration of the esophageal defect was achieved in 60 of 77 patients. The average duration of application was 11.0 days, and a median of 2.75 E-VAC systems were used. For 21 of the 77 patients, E-VAC therapy was combined with the placement of self-expanding metal stents. This study demonstrates that E-VAC therapy provides an additional treatment option for esophageal wall defects. Esophageal defects and mediastinal abscesses can be treated with E-VAC therapy where endoscopic stenting may not be possible. A prospective multi-center study has to be directed to bring evidence to the superiority of E-VAC therapy for patients suffering from upper GI defects.

    Sleeve gastrectomy has become one of the main bariatric procedures over the last few years. This can be explained by the relative simplicity and high effectiveness of this method. Yet, it causes complications as any other method. Staple line leaks are the most frequent ones. According to different sources, this complication may occur with 0-7% frequency. Until 2013, surgery was the only effective treatment method for this complication. However, reoperations considerably increased treatment cost and patient morbidity. The aim of this study is to present the possibilities of endoscopic treatment of leaks after laparoscopic sleeve gastrectomy. From 2014 to 2016 14, cases of leaks following sleeve gastrectomy were diagnosed in our Department in Łódź. All of them were treated with MEGA stent in order to cover the leak site. Due to severe peritonitis, 3 patients had to undergo surgery prior to implantation of the prosthesis. Another patient underwent an unsuccessful attempt of leak closing via OTSC method prior to implantation of the prosthesis. Patients were nourished from the 3rd day after the surgery. On average, prostheses were removed on the 34th day after the implantation. The leak was fully sealed in 13 out of 14 cases. In 10 cases the leak was fully healed. There were 2 cases of patients' deaths: the result of a multi-organ failure in one case and early esophageal perforation in the other one. The overall success rate was 90.9%. Sealing leaks occurring after sleeve gastrectomy with MEGA stents represent an effective method and should become the technique of choice.

    Peroral endoscopic myotomy (POEM) is an evolving therapeutic modality for achalasia. We aim to determine efficacy of POEM for the treatment of achalasia and compare it with laparoscopic Heller's myotomy (LHM). Systematic review and meta-analyses was conducted on 19 studies using POEM for achalasia. Pubmed, Medline, Cochrane, and Ovid databases, were searched using the terms 'achalasia', 'POEM', 'peroral endoscopic myotomy', 'per oral endoscopic myotomy', and 'per-oral endoscopic myotomy'. Reduction in Eckhart's score and lower esophageal sphincter (LES) pressure were the main outcome measures. A total of 1,045 patients underwent POEM in 29 studies. Ninety patients undergoing POEM was compared with 160 undergoing LHM in five studies. Nineteen and 14 studies, respectively, evaluated for Eckhart's score and LES pressure. There was significant reduction in Eckhart's score and LES pressure with effect sizes of -7.95 (p < 0.0001) and -7.28 (p < 0.0001), respectively. There was significant heterogeneity among the studies [(Q = 83.06; I (2) = 78.33 %; p < 0.0001) for Eckhart's score and (Q = 61.44; I (2) = 75.68 %; p < 0.0001) for LES pressure]. There were no differences between POEM and LHM in reduction in Eckhart's score, post-operative pain scores and analgesic requirements, length of hospital stay, adverse events, and symptomatic gastroesophageal reflux/reflux esophagitis. Operative time was significantly lower for POEM. POEM is effective for achalasia and has similar outcomes as LHM. Multicenter randomized trials need to be conducted to further compare the efficacy and safety of POEM between treatment naïve achalasia patients and those who failed treatment.

    Our experience in the endoscopic treatment of vesicoureteral reflux (VUR) has significantly increased during the last decade. To help develop diagnostic tests to check the success of this procedure, we evaluated the accuracy of surgeons' intraoperative observations as a predictor of treatment results. We performed a prospective study of patients with VUR who were endoscopically treated during 1 year (106 renal units). Patients' age and gender, laterality, material used, grade of reflux, presence of ureteral duplication or associated pathology, and morphology of ureteral orifice were recorded as predictive factors related to the success rate. Surgeon and assistant indicated at the end of the endoscopic procedure whether the VUR was cured or not for each renal unit. These estimations were compared with postoperative voiding cystourethrogram results. Overall cure rate was 75.5%. Positive predictive value (PPV) for surgeon's opinion was 0.79 and negative predictive value (NPV) was 0.40. Statistical analysis demonstrated that the association between the surgeon's opinion and the cure rate was low with a Kappa value of 0.171 (p = 0.30). PPV of assistant's opinion was 0.80 and NPV was 0.40, with a Kappa value of 0.2 (p = 0.13). Concordance of surgeon and assistant's opinion resulted in PPV of 0.79 and NPV of 0.53 (Kappa = 0.261). Kappa value did not improve when surgeon's opinion was related to other factors such as the material employed, grade of reflux, presence of ureteral duplication or associated pathology and morphology of the ureteral orifice. In our experience, surgeon's opinion is not an accurate tool to predict the outcome of endoscopic treatment of VUR. Copyright © 2013 Journal of Pediatric Urology Company. Published by Elsevier Ltd.

    To Improve the diagnosis of duodenal ulcer and preneoplastic changes of gastroduodenal transition. 112 patients with duodenal ulcer, 208 healthy pearsons of three age periods: second period of mature age, elderly and senile age were examined. Video endoscopy equipment company "OLYMPUS" (Japan), morphological methods and the determination of Helicobacter pylori (Hp) were used. The connecting line of gastric and duodenal mucous membrane can be located on the gastric side of the pylorus (13% in normal cases and 22.3% in cases of ulcer disease), on pylorus and go into the bulbus of duodenum (87% and 77.7 %, respectively), in cases of duodenal ulcer the connecting line more often has jagged and tongue-shaped form. Mucous membrane forms folds in prepyloric part of the stomach most often on the front wall in healthy pearsons in 14.4% of cases, in patients with duodenal ulcer--in 75.9%. The number of folds decreases with age. HP, atrophy, intestinal metaplasia of the mucous membrane is more often found in duodenal ulcer disease--76.8%, 69.7% and 62.5% comparing with healthy persons: 51.4%, 5.3% and 47.7% respectively. Frequency of preneoplastic changes increases with age. The individual differences of the mucous membrane of the gastroduodenal transition are identified. They are expressed in the particular location and shape of the connecting line of gastric and duodenal mucous membranes in normal cases and in cases of ulcer disease in different age groups. Some endoscopic changes requiring biopsy and morphological studies are revealed.

    Per-oral endoscopic myotomy (POEM) is an emerging treatment for achalasia. Pneumatic dilation, botulinum toxin injection, and previous myotomy increase the difficulty of subsequent Heller myotomy, but their impact on POEM remains unknown. The purpose of this study was to compare patients who had undergone prior treatment for their achalasia to those undergoing POEM as an initial therapy. All patients undergoing POEM were entered into a prospective database from August 2012 to October 2014. Data collected included demographics, dysphagia and symptom survey scores, operative time, clips required for mucosotomy closure, perioperative complications and length of hospital stay. Forty-five patients underwent POEM during the study period. Fifteen (30%) had undergone previous treatment (seven Botox injection, five pneumatic dilation and three Heller myotomy). Primary POEM patients were younger than those who had had prior treatment (mean age 46 ± 17 vs. 64 ± 12 years, p myotomy or perioperative complications in either group. Operative time for primary POEM was 103 ± 27 versus 102 ± 29 min following prior treatment (p = 0.84). Mucosotomy closure required a median 7 (4-16) and 8 (5-16) clips, respectively (p = 0.08). Length of stay was 1 day in each group. Median dysphagia scores decreased from 4 (0-5) to 1 (0-4) following primary POEM and 4 (0-5) to 0 (0-4) in the prior treatment group (p = 0.45) during a median follow-up of 10 months (5-17 months). All patients in each group expressed satisfaction with their procedure and would undergo the procedure again given the benefit of hindsight. Per-oral endoscopic myotomy is a safe and effective treatment for achalasia which improves dysphagia and disease-specific quality of life. Previous endoscopic or laparoscopic treatment of achalasia does not affect the performance or early outcome of POEM.

    In the differential diagnosis of biliary obstruction with unknown etiology, biliary fascioliasis should be considered in endemic and nonendemic regions. After diagnostic evaluation, endoscopic retrograde cholangiopancreatography (ERCP) was performed for etiological evaluation and/or treatment of biliary obstruction in five patients with a mean age of 55.8 years. Endoscopic sphincterotomy and cholangiogram revealed linear filling defects in the biliary system. Fasciola hepatica parasites were extracted using balloon and basket catheters in two and three patients, respectively. No morbidity or mortality was observed. F. hepatica infection should be considered as a differential diagnosis of biliary obstruction with unknown etiology in endemic and non-endemic regions. ERCP can be the standard diagnostic and/or therapeutic procedure in cases of biliary obstruction due to fascioliasis. Due to slippery and gel-like characteristics of the parasite, use of a basket catheter in semi-opened position may be required in case of unsuccessful extraction using a balloon catheter.

    Full Text Available Background. The aim of this study was to compare the effect of high-dose oral rabeprazole versus high-dose IV PPI on rebleeding after endoscopic treatment of bleeding peptic ulcers. Methods. This was a two-center, prospective, randomized, controlled trial. Patients with a high-risk bleeding peptic ulcer had endoscopic hemostasis and were randomly assigned to the high-dose oral rabeprazole group (20 mg twice daily for 72 hours or the high-dose IV omeprazole group (80 mg as a bolus injection followed by continuous infusion at 8 mg/h for 72 hours. Results. The study was stopped because of slow enrollment (total n=106. The rebleeding rates within 3 days were 3.7% (2 of 54 patients given oral rabeprazole and 1.9% (1 of 52 patients given IV omeprazole (P=1.000. The rebleeding rates after 3 days were 1.9% and 0% (P=1.000, respectively. The surgical intervention rates were 3.7% and 0% (P=0.495, and the mortality rates were 1.9% and 0% (P=1.000, respectively. Conclusions. The effect of high-dose oral rabeprazole did not differ significantly from that of high-dose IV omeprazole on rebleeding, surgical intervention, or mortality after endoscopic treatment of bleeding peptic ulcers, but this requires further evaluation.

    Full Text Available Aim: To determine the efficacy and potential complications of double-J ureteric stents in the treatment of persistent or progressive primary obstructive megaureter in pediatric patients within our institution. Materials and Methods: A retrospective case-note review of all patients with double-J ureteric stents, between 1997 and 2004, was performed. In all, 38 stents were inserted in 31 patients aged between 2 months and 15 years of age. Complications and results of follow-up investigations and the need for follow-up investigations were recorded. Patients were followed up clinically and radiologically for a minimum of 2 years following stent insertion. Results: Endoscopic placement of double-J ureteric stents in childhood is straightforward and complications are uncommon (8/38 insertions. In non-resolving or progressive primary non-refluxing megaureter, double-J ureteric stenting alone is effective with resolution of primary non-refluxing megaureter in 66% of cases (25/38 insertions. Conclusions: Ureteric stenting provides an alternative to early surgery in patients with primary non-refluxing megaureter. The youngest patient in our series was 2 months old at the time of endoscopic ureteric double-J stent insertion. Endoscopic placement of ureteric double-J stents should be considered as a first-line treatment in the management of persistent or progressive non-refluxing megaureter leading to progressive hydronephrosis or pyonephrosis.

    Gastric per oral endoscopic myotomy (G-POEM) of the pylorus is a technique that is recently being used to treat gastroparesis. Our aim was to report our experience in performing G-POEM for refractory gastroparesis of different etiologies and determine symptom improvement. Thirteen patients undergoing G-POEM are reported. Pre- and post-procedure gastric emptying study (GES) and PAGI-SYM for symptom severity were obtained. Patients underwent G-POEM by creating a submucosal tunnel starting in the greater curvature of the distal antrum and extending it to the beginning of the duodenal bulb, followed by a full thickness pyloromyotomy. All 13 gastroparesis patients successfully underwent G-POEM (one diabetic [DGp], four idiopathic [IGp], eight postsurgical [PSGp]). Postsurgical patients included 4 s/p esophagectomy for esophageal cancer, 3 s/p Nissen fundoplication, and 1 s/p esophagectomy for achalasia. There were no procedure-related side effects. Of 11 patients completing follow-up questionnaires, eight were improved subjectively (four patients reported considerably better, four patients somewhat better, one unchanged, and two worse). Individual symptom severity scores tended to improve, particularly vomiting, retching, and loss of appetite. Of six patients that had post-G-POEM GES; GES improved in four, unchanged in one, and worsened in one). G-POEM for treatment of refractory gastroparesis appears to be a feasible and safe technique that can be successfully performed in patients with a variety of etiologies including different types of postsurgical gastroparesis. Our initial experience suggests that the majority of patients report some improvement in symptoms, particularly symptoms of vomiting, retching, and loss of appetite. Further experience is needed to determine the efficacy and safety of G-POEM and predict those who best respond to this treatment.

    Papillary ureteral neoplasm of low malignant potential (PUNLMP) is a rare diagnosis, and to our knowledge, has not yet been reported in the upper urinary tract. In this study, we aimed to present our experience in managing a very rare diagnosis, PUNLMP, in the upper urinary tract, with endoscopic treatment. Files of patients who received surgery between January 2007 and January 2013 for upper urinary tract tumors were reviewed and patients treated for PUNLMP in the upper urinary tract in 4 urology clinics were reviewed. Patients included in the study had at most 2 tumors in the ureter and had a pathology of PUNLMP. The study included 11 patients with a mean age of 58.5 years. There were 9 men, and 2 women with a smoking rate of 81.8%. Nine patients (8 in the distal and 1 in the mid ureter) were managed using a semirigid ureteroscope. Two patients (1 with mid ureteral and 1 proximal) were treated using flexible ureteroscopy. The mean hospital stay was 1.56 days. Mean surgical time was 37.18 ± 7.14 minutes. The mean follow-up was 31.5 (range, 7-72) months. In the follow-ups, 3 patients had recurrences of 3, 2, and 4 mm in 9, 15, and 17 months, respectively. For tumors with a low risk of progression and relatively low risk of recurrence, organ-sparing treatments should be the choice of preference. To support our initial findings, randomized controlled studies on larger cohorts should be designed. Copyright © 2014 Elsevier Inc. All rights reserved.

    Purpose. We reviewed our 20 years of experience and the current literature regarding the long-term outcome of endoscopic treatment of vesicoureteric reflux (VUR) using the different tissue bulking substances with a special emphasis on the long-term efficacy. Material and Methods. Our own experience and the current literature on the long-term results after endoscopic treatment using various bulking agents were reviewed. Results. Short-term data following endoscopic treatment of VUR is similar to the various substances and comparable in the majority of the series to the success rate following open surgery. Recently, a relatively high recurrence rate was noticed especially with the use of dextranomer hyaluronic acid (Dx/HA) as a tissue augmenting material which raises the need for further search for alternative substances. Conclusions. Unfortunately, there is a significant shortage of evidence-based literature on the long-term followup after endoscopic correction of reflux with various substances. No doubt, there is a high recurrence rate during long-term followup after Dx/HA injection, and there is probably lack of proper evaluation regarding the long-term efficacy of other bulking materials. These facts demand long-term close observation and long-term studies beyond the routine protocols following endoscopic treatment of VUR and the correct parental counseling upon the endoscopic correction.

    2017-01-01

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

    Purpose: Endoscopic examinations are routine procedures for head-and-neck cancer patients. Our goal is to develop a method to map the recorded video to CT, providing valuable information for radiotherapy treatment planning and toxicity analysis. Methods: We map video frames to CT via virtual endoscopic images rendered at the real endoscope’s CT-space coordinates. We developed two complementary methods to find these coordinates by maximizing real-to-virtual image similarity:(1)Endoscope Tracking: moves the virtual endoscope frame-by-frame until the desired frame is reached. Utilizes prior knowledge of endoscope coordinates, but sensitive to local optima. (2)Location Search: moves the virtual endoscope along possible paths through the volume to find the desired frame. More robust, but more computationally expensive. We tested these methods on clay phantoms with embedded markers for point mapping and protruding bolus material for contour mapping, and we assessed them qualitatively on three patient exams. For mapped points we calculated 3D-distance errors, and for mapped contours we calculated mean absolute distances (MAD) from CT contours. Results: In phantoms, Endoscope Tracking had average point error=0.66±0.50cm and average bolus MAD=0.74±0.37cm for the first 80% of each video. After that the virtual endoscope got lost, increasing these values to 4.73±1.69cm and 4.06±0.30cm. Location Search had point error=0.49±0.44cm and MAD=0.53±0.28cm. Point errors were larger where the endoscope viewed the surface at shallow angles<10 degrees (1.38±0.62cm and 1.22±0.69cm for Endoscope Tracking and Location Search, respectively). In patients, Endoscope Tracking did not make it past the nasal cavity. However, Location Search found coordinates near the correct location for 70% of test frames. Its performance was best near the epiglottis and in the nasal cavity. Conclusion: Location Search is a robust and accurate technique to map endoscopic video to CT. Endoscope

    Hydrocephalus develops in up to 90% of patients born with myelomeningocele. Although endoscopic third ventriculostomy (ETV) is currently considered the preferred treatment for obstructive hydrocephalus, its results have been inconsistent in patients with myelomeningocele. This study focuses on clinical and radiologic outcomes of ETV in children with hydrocephalus related to myelomeningocele. Medical records of 18 pediatric patients with myelomeningocele treated with ETV from 1998 to 2015 at the Centro Hospitalar São João (Porto, Portugal) were reviewed retrospectively. Patients' caregivers were contacted to evaluate their clinical manifestations before and after surgery regarding signs and symptoms of hydrocephalus and Chiari malformation. Control neuroradiologic imaging of 9 patients was obtained and analyzed. Success of ETV was defined by clinical resolution and radiologic confirmation. ETV was successful in 8 of 18 cases (44.4%). Groups of patients were compared according to age at the time of surgery, with a 40% (2/5) success rate in newborns and a 50% success rate (3/6) in children older than 1 year. Eight patients underwent ETV as a first option, with a 37.5% success rate. Ten patients underwent the procedure after previous ventriculoperitoneal shunt (VPS), 5 for malfunction and 5 for VPS infection with 60% and 40% success rates, respectively. Early postoperative complications occurred in 2 patients. ETV can be performed in patients with myelomeningocele and hydrocephalus with success rates of almost 50%. Prior VPS or VPS malfunction or infection do not contraindicate ETV. If possible, the procedure should be delayed until the patient is at least 1 month old. Copyright © 2017 Elsevier Inc.

    Ingested button batteries (BB) can cause corrosive damage of digestive mucosa within minutes. Immediate endoscopic removal of esophageal BB has been clearly established, but the management of BB located in the stomach is still controversial. To describe demographic, clinical, radiologic, and endoscopic characteristics of a series of pediatric patients evaluated for BB ingestion. Retrospective analysis of clinical charts belonging to children younger than 15 years, who underwent endoscopic removal of BB at Clínica Alemana of Santiago, between November 2007 and November 2011. Twenty-five patients subjected to upper endoscopy were analyzed; median age, 31 months; 15 were male (60%), and 11 patients (46%) were symptomatic after ingestion. The BB ingestion was confirmed by radiograph. Endoscopy revealed 10 patients with BB in the esophagus, 12 patients in the stomach and 3 distal to duodenum. Range time between ingestion and endoscopy was 2 to 10 hours for esophageal BB and 2 hours to 3 days for gastric BB. Eight of the 22 BBs removed had a diameter of 20 mm or greater, 6 of them were located in the esophagus and 2 in stomach. The BB color changes were observed in 14 of the 22 BBs. Breakage of battery edges was present in 11 of the 22 batteries. All patients with esophageal BB and 6 of those 12 with gastric BB presented mucosal damage. Esophageal BB cause damage within hours. The BB located in the stomach may also cause damage early. Extraction of gastric BB before 48 hours should be considered.

    Gastrointestinal endoscopy is a standard diagnostic tool for gastrointestinal ulcers and cancer. In this study, we have developed recombinant human epidermal growth factor-containing ulcer-coating polymeric sol-gel for endoscopic application. Chitosan and pluronic F127 were employed for their thermoresponsive and bioadhesive properties. At temperatures below 21, polymeric sol-gel remains liquid during endoscopic application and transforms to gel at body temperature after application on ulcers. In an in vitro cellular wounding assay, recombinant human epidermal growth factor sol-gel significantly enhanced the cell migration and decreased the wounding area (68%) compared to nontreated, recombinant human epidermal growth factor solution, and sol-gel without recombinant human epidermal growth factor (42, 49, and 32 % decreased at day 1). The in vivo ulcer-healing study was performed in an acetic acid-induced gastric ulcer rat model and proved that our recombinant human epidermal growth factor endoscopic sol-gel facilitated the ulcer-healing process more efficiently than the other treatments. Ulcer sizes in the recombinant human epidermal growth factor sol-gel group were decreased 2.9- and 2.1-fold compared with those in the nontreated group on days 1 and 3 after ulceration, respectively. The mucosal thickness in the recombinant human epidermal growth factor sol-gel group was significantly increased compared to that in the nontreated group (3.2- and 6.9-fold on days 1 and 3 after ulceration, respectively). In a gastric retention study, recombinant human epidermal growth factor sol-gel stayed on the gastric mucosa more than 2 h after application. The present study suggests that recombinant human epidermal growth factor sol-gel is a prospective candidate for treating gastric ulcers via endoscopic application.

    To present our cases of ureteral obstruction after endoscopic treatment of vesicoureteral reflux (VUR) with dextranomer/hyaluronic acid (Dx/HA). We collected data from patients who had suffered ureteral obstruction after endoscopic treatment of VUR with Dx/HA in our institution. From April 2002 to April 2011 we treated endoscopically 475 ureters with VUR, and detected 5 ureteral obstructions. Median age at reflux treatment was 39 months. Reflux grade before treatment was III in one patient and IV in four. Three ureterovesical junctions (UVJ) were blocked after a second endoscopic treatment. The median of Dx/HA injected was 1 ml (0.6-1.1). In two patients ureteral obstruction presented acutely and was treated with a ureteral stent. In the other three, the ureteral obstruction appeared gradually and was detected by ultrasound scans and MAG3 diuretic renogram; one underwent nephrectomy because of poor renal function, and the other two were treated with endoscopic dilatation of the UVJ. In all these patients both reflux and obstructions have resolved. On preoperative cystography, three of the patients had a narrowed distal ureter, and probably had a refluxing and obstructive megaureter. Other causes are not clear, except for those patients with acute presentation in whom edema of the UVJ was found. Ureteral obstruction after endoscopic treatment of VUR is rare. Endoscopic intervention such as ureteral stent placement or high-pressure balloon dilatation of the UVJ has good results as a treatment of acute and delayed obstruction.

    The influence of Helicobacter pylori (HP) in inflammatory disorders of the digestive mucosa has been the subject of several studies since socioeconomic, personal and environmental factors were implicated in the bacteria transmission. To correlate the inflammatory endoscopic findings with HP infection and the onset of mucosal diseases mucous of the upper digestive tract. Comparative observational study, in which were collected data from 2247 patients who underwent upper endoscopy and biopsies for HP with urease test. The patients were divided into two groups: HP+ and HP- (control) in which endoscopic findings were observed for the following changes: esophagitis, esophageal ulcer, gastritis, erosive gastritis, gastric ulcer, bulboduodenitis, bulbar ulcer and without disease. As for esophagitis, there was little disparity in the distribution favorable to HP+ group (HP+ =67.11% and HP- =69.89%) and esophageal ulcer (HP+ =0% and HP- =0, 21%). Gastritis was favorable to HP- group (HP+ =78.34% and HP- =73.63%), as well as erosive gastritis (HP+ = 67,11% and HP- = 64,55%), in bulboduodenitis (HP+ =1,87% and HP- 1,23%), in gastric ulcer (HP+ =2,14% and HP- =2,03%) and in the absence of alterations in the HP+ group (4.81%) with the HP- control group (6,30%), in which there was little disproportion in favor of HP- group, but without statistical significance. As for the bulbar ulcer (HP +=10.16% and HP- =4.48%), there was statistically significant (p=0.00001). There is no difference between HP+ and HP- groups in inflammatory changes in endoscopic gastroduodenal mucosa, except for the relationship between HP and bulbar ulcer.

    The craniovertebral junction (CVJ), or the craniocervical junction (CCJ) as it is otherwise known, houses the crossroads of the CNS and is composed of the occipital bone that surrounds the foramen magnum, the atlas vertebrae, the axis vertebrae, and their associated ligaments and musculature. The musculoskeletal organization of the CVJ is unique and complex, resulting in a wide range of congenital, developmental, and acquired pathology. The refinements of the transoral approach to the CVJ by the senior author (A.H.M.) in the late 1970s revolutionized the treatment of CVJ pathology. At the same time, a physiological approach to CVJ management was adopted at the University of Iowa Hospitals and Clinics in 1977 based on the stability and motion dynamics of the CVJ and the site of encroachment, incorporating the transoral approach for irreducible ventral CVJ pathology. Since then, approaches and techniques to treat ventral CVJ lesions have evolved. In the last 40 years at University of Iowa Hospitals and Clinics, multiple approaches to the CVJ have evolved and a better understanding of CVJ pathology has been established. In addition, new reduction strategies that have diminished the need to perform ventral decompressive approaches have been developed and implemented. In this era of surgical subspecialization, to properly treat complex CVJ pathology, the CVJ specialist must be trained in skull base transoral and endoscopic endonasal approaches, pediatric and adult CVJ spine surgery, and must understand and be able to treat the complex CSF dynamics present in CVJ pathology to provide the appropriate, optimal, and tailored treatment strategy for each individual patient, both child and adult. This is a comprehensive review of the history and evolution of the transoral approaches, extended transoral approaches, endoscopie assisted transoral approaches, endoscopie endonasal approaches, and CVJ reduction strategies. Incorporating these advancements, the authors update the

    We histologically investigated the cause of failed endoscopic treatment of vesicoureteral reflux with dextranomer/hyaluronic acid injections in children. A total of 192 children underwent dextranomer/hyaluronic acid injection at our institution between January 2008 and September 2010. The study population consisted of 13 children (22 ureters) with vesicoureteral reflux who underwent ureteroneocystostomy following failed endoscopic injections (1 to 2) of dextranomer/hyaluronic acid. In all cases the dextranomer/hyaluronic acid was implanted in the mucosa of the mid to distal ureteral tunnel following hydrodistention of the ureter. The medical records were reviewed, and specimens of the archived distal ureters removed during surgery were examined histologically. Mean patient age was 4.1 years. Mean dose of dextranomer/hyaluronic acid was 0.9 ml (both treatments) and mean lag between treatments was 13.4 months. Indications for open surgery were recurrent urinary tract infections and/or residual or aggravated reflux grade IV or higher. Histological study revealed that the dextranomer/hyaluronic acid was malpositioned in 21 of 22 ureters, residing in the muscle fibers in 2, adventitia in 14 and periureteral space in 5. This is the first known study to provide a histologically proved cause of failure of endoscopic treatment of vesicoureteral reflux with dextranomer/hyaluronic acid injections in children. Malpositioning of the material outside the submucosal ureter was identified in a high percentage of cases. Larger studies are needed to corroborate these findings.

    The objective of the study is to investigate the impact of receiving daily WeChat services on one's cell phone on adherence to corticosteroid nasal spray treatment in chronic rhinosinusitis (CRS) patients after functional endoscopic sinus surgery (FESS). This study was a two-arm, randomized, follow-up investigation. Patients with chronic rhinosinusitis with/without nasal polyps following bilateral FESS were randomised to receive, or to not receive, daily WeChat service on their cell phone to take corticosteroid nasal spray treatment. A prescription of budesonide aqueous nasal spray 128 µg bid was given to all the subjects. Then they returned to the clinic after 30, 60, 90 days. The primary study outcome was adherence to nasal spray treatment, whereas secondary outcomes were change in endoscopic findings and SinoNasal Outcome Test-20 (SNOT-20). On the whole, there was a significant inter-group difference in the change of adherence rate (F = 90.88, p = 0.000). The WeChat group had much higher adherence rate than the control group during the follow-up. In terms of postoperative endoscopic scores and SNOT-20, except granulation score, no significant differences were observed between the two randomization groups. WeChat services are already after a short period of observation associated with improved adherence to corticosteroid nasal spray treatment in CRS patients after FESS.

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

    Full Text Available Abstract Background Lethal pancreatitis has been reported after treatment for common bile duct stones using small endoscopic papillary balloon dilation. Methods We retrospectively evaluated the safety and efficacy of using large balloon dilation alone without the use of sphincterotomy for the treatment of large common bile duct stones in Kaohsiung Veterans General Hospital. Success rate of stone clearance, procedure-related adverse events and incidents, frequency of mechanical lithotripsy use, and recurrent stones were recorded. Results A total of 247 patients were reviewed in the current study. The mean age of the patients was 71.2 years. Most of them had comorbidities. Mean stone size was 16.4 mm. Among the patients, 132 (53.4% had an intact gallbladder and 121 (49% had a juxtapapillary diverticulum. The mean size of dilating balloon used was 13.2 mm. The mean duration of the dilating procedure was 4.7 min. There were 39 (15.8% patients required the help of mechanical lithotripsy while retrieving the stones. The final success rate of complete retrieval of stones was 92.7%. The rate of pancreatic duct enhancement was 26.7% (66/247. There were 3 (1.2% adverse events and 6 (2.4% intra-procedure bleeding incidents. All patients recovered completely after conservative and endoscopic treatment respectively, and no procedure-related mortality was noted. 172 patients had a follow-up duration of more than 6 months and among these, 25 patients had recurrent common bile duct stones. It was significantly correlated to the common bile duct size (p = 0.036 Conclusions Endoscopic papillary large balloon dilation alone is simple, safe, and effective in dealing with large common bile duct stones in relatively aged and debilitated patients.

    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, performing 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.

  17. Current Innovations in Endoscopic Therapy for the Management of Colorectal Cancer: From Endoscopic Submucosal Dissection to Endoscopic Full-Thickness Resection

    Directory of Open Access Journals (Sweden)

    Shintaro Fujihara

    2014-01-01

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

    Anastomotic bile duct complications after liver transplantation (LT) have been treated endoscopically by dilation and plastic tube stenting, with the stent therapy having moved toward using covered, self-expandable metallic stents (cSEMS) in recent years. The aim of this study was to analyze therapy outcome of post-LT anastomotic complications using cSEMS. Seventeen post-LT patients had 29 cSEMS (Allium stent, n = 23; Wallstent, n = 4; Micro-Tech, n = 2) placed during endoscopic retrograde cholangiopancreatography (ERCP). The fully covered stents (Allium, Micro-Tech) were placed entirely inside the common bile duct. Data were collected and analyzed in a retrospective manner. These 17 patients had 19 stent treatment periods. Resolution was eventually established in all patients. There were four (14%) stent migrations. Pancreatitis was seen after one ERCP procedure, whereas five cases of cholangitis were seen. Treatment of post-LT anastomotic complications with cSEMS seems to be both safe and efficient. Further assessment regarding indications, stent types and stenting time is needed.

    Purpose. Minimal data exists comparing dextranomer/hyaluronic acid (Dx/HA) and calcium hydroxyapatite (CaHA) for the endoscopic treatment of VUR in the hands of a single user. Materials and Methods. We reviewed our consecutive single-user case series of 27 children (42 ureters) receiving endoscopic treatment with CaHA and 21 children (33 ureters) who received Dx/HA injection. Children receiving CaHA injections were divided into two groups of 13 and 14 patients (Coaptite I and II) to assess the learning curve effects. Postoperatively, RBUS and VCUG were performed. Multiple regression analysis was performed to assess statistical significance of success rates. Results. The total CaHA group had a per-ureter success rate (Grade 0) of 52% after one injection. When separated into two cohorts, the single injection per-ureter success rates were 43% for Coaptite I and 62% for Coaptite II. In contrast, the Dx/HA series had a single injection per-ureter success rate (Grade 0) of 78%. Conclusions. Our consecutive case experience shows improved results for Dx/HA compared to CaHA, though the learning curve effects and evolution of injection technique likely played a role in the improved outcomes in the Dx/HA cohort. A randomized controlled multicenter trial would provide the most accurate data comparing these two agents. PMID:24235969

    Full Text Available Purpose. Minimal data exists comparing dextranomer/hyaluronic acid (Dx/HA and calcium hydroxyapatite (CaHA for the endoscopic treatment of VUR in the hands of a single user. Materials and Methods. We reviewed our consecutive single-user case series of 27 children (42 ureters receiving endoscopic treatment with CaHA and 21 children (33 ureters who received Dx/HA injection. Children receiving CaHA injections were divided into two groups of 13 and 14 patients (Coaptite I and II to assess the learning curve effects. Postoperatively, RBUS and VCUG were performed. Multiple regression analysis was performed to assess statistical significance of success rates. Results. The total CaHA group had a per-ureter success rate (Grade 0 of 52% after one injection. When separated into two cohorts, the single injection per-ureter success rates were 43% for Coaptite I and 62% for Coaptite II. In contrast, the Dx/HA series had a single injection per-ureter success rate (Grade 0 of 78%. Conclusions. Our consecutive case experience shows improved results for Dx/HA compared to CaHA, though the learning curve effects and evolution of injection technique likely played a role in the improved outcomes in the Dx/HA cohort.

    Fibrous dysplasia (FD) and aneurysmal bone cyst involving the facial skeleton are rare but their synchronous association in other parts of the body is well-known. The most common treatment for these lesions has been based on surgical resection using an external approach. Only recently has the endonasal endoscopic approach been utilized for the partial or complete removal of these lesions. In this report, we attempt to outline the effectiveness of the endonasal endoscopic approach for the treatment of a 5-year-old child affected by a fibrous dysplasia associated with an aneurysmal bone cyst of the right maxillary.

    Endoscopic injection of non-animal-stabilized hyaluronic acid/dextranomer gel is an increasingly recognized treatment option for vesicoureteral reflux. The procedure is minor compared with open surgery and, when successful, avoids the need for long-term antibiotic prophylaxis. We present data from 3 years of using non-animal-stabilized hyaluronic acid/dextranomer gel to treat children with vesicoureteral reflux. Pediatric patients aged 16 years with uncomplicated primary vesicoureteral reflux were recruited for endoscopic treatment with non-animal-stabilized hyaluronic acid/dextranomer gel. A follow-up voiding cystourethrogram was scheduled at 2 weeks after treatment, and vesicoureteral reflux resolution was defined as grade 0. Repeat non-animal-stabilized hyaluronic acid/dextranomer gel treatment was offered to patients with persistent vesicoureteral reflux. Of 178 patients treated, 12 were lost to follow-up or yet to undergo post-treatment voiding cystourethrogram. The 166 remaining patients (efficacy population) had a mean age of 4.21 years (range: 0-16), and the median reflux grade was 3 (range: 1-5). Vesicoureteral reflux was resolved in 81.9% of patients and 86.4% of ureters after initial endoscopic treatment with non-animal-stabilized hyaluronic acid/dextranomer gel. The overall reflux resolution rate for patients increased to 89.6% after a second treatment in 19 patients, and 90.2% after a third treatment in 1 patient. No adverse events were reported. Five patients underwent open ureteral reimplantation after failed endoscopic injections. Endoscopic treatment with non-animal-stabilized hyaluronic acid/dextranomer gel is effective in a high proportion of children with vesicoureteral reflux and, in our opinion, should be considered as a first-line treatment option.

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

    Detachable mini-loop ligation is useful for endoscopic management of esophageal varices. This study evaluated the treatment of gastroduodenal angiodysplasia by detachable mini-loop ligation. Eleven patients (9 women, 2 men; mean age 61 [18] years) with bleeding gastroduodenal angiodysplasia were treated endoscopically by detachable mini-loop ligation. At endoscopy, two patients had actively bleeding lesions. By using a ligating device, a detachable nylon ring was inserted through the accessory channel of an endoscope and opened at the rim of a transparent ligation chamber attached to the tip of the instrument. The angiodysplasia was aspirated into the chamber, and the mini-loop was closed and detached. Initial ligation therapy was successful in all patients without inducing uncontrollable bleeding. In one patient, two mini-loops were applied to the same angiodysplastic lesion. The only significant complication was severe GI bleeding from a duodenal ulcer that developed at the ligation site in one patient. This was successfully treated by endoscopic placement of hemoclips. Detachable mini-loop ligation is an effective and safe modality for endoscopic treatment of bleeding gastroduodenal angiodysplasia.

    In achalasia, muscle spasm may involve the proximal esophagus. When the muscle spasm is located in the proximal esophagus, conventional per oral endoscopic myotomy (POEM) may not be sufficient to relieve symptoms. In this paper, we describe retrograde endoscopic myotomy (REM) as a novel approach to perform myotomy of the proximal esophagus, with the application of a navigation tool for anatomical guidance during REM. We aim to evaluate the feasibility and safety of REM and usefulness of the navigation during REM. A 42-year-old male with type III achalasia who was treated with laparoscopic myotomy with fundoplication, multiple pneumatic balloon dilations, Botox injections and anterior POEM of the middle and distal esophagus without symptomatic effect. Repeated high-resolution- manometry (HRM) revealed occluding contractions of high amplitude around and above the aortic arch. A probe-based real-time electromagnetic navigation platform was used to facilitate real-time anatomical orientation and to evaluate myotomy position and length during REM. The navigation system aided in identifying the major structures of the mediastinum, and position and length of the myotomy. Twelve weeks after REM, the Eckardt score fell from seven at baseline seven to two. We also observed improvement with reduction of the pressure at the level of previous spasms in the proximal esophagus from 124 mmHg to 8 mmHg on HRM. REM makes the proximal esophagus accessible for endoscopic myotomy. Potential indication for REM is motility disorders in the proximal esophagus and therapy failure after POEM. © 2017 John Wiley & Sons Ltd.

    Colocolonic intussusception is an uncommon cause of intestinal obstruction in children. The most common type is idiopathic ileocolic intussusception. However, pathologic lead points occur approximately in 5% of cases. In pediatric patients, Meckel's diverticulum is the most common lead point, followed by polyps and duplication. We present a case of recurrent colocolonic intussusception which caused colonic obstruction in a 10-year-old boy. A barium enema revealed a large polypoid mass at the transverse colon. Colonoscopy showed a colonic polyp, 3.5 centimeters in diameter, which was successfully removed by endoscopic polypectomy.

    Full Text Available Abstract Background Spontaneous intracerebral hemorrhage is a disease with high morbidity, high disability rate, high mortality, and high economic burden. Whether patients can benefit from surgical evacuation of hematomas is still controversial, especially for those with moderate-volume hematomas in the basal ganglia. This study is designed to compare the efficacy of endoscopic surgery and conservative treatment for the moderate-volume hematoma in spontaneous basal ganglia hemorrhage. Methods Patients meet the criteria will be randomized into the endoscopic surgery group (endoscopic surgery for hematoma evacuation and the best medical treatment or the conservative treatment group (the best medical treatment. Patients will be followed up at 1, 3, and 6 months after initial treatment. The primary outcomes include the Extended Glasgow Outcome Scale and the Modified Rankin Scale. The secondary outcomes consist of the National Institutes of Health Stroke Scale and the mortality. The Barthel Index(BI will also be evaluated. The sample size is 100 patients. Discussion The ECMOH trial is a randomized controlled trial designed to evaluate if endoscopic surgery is better than conservative treatment for patients with moderate-volume hematomas in the basal ganglia.

    Full Text Available Objective “Traditional subureteral transurethral injection” (STING and “Double hydrodistention-implantation” (Double-HIT injection techniques for vesicoureteral reflux (VUR treatment are a less invasive, yet very effective options. The influence of injection techniques in treatment success is not adequately searched in children with overactive bladder syndrome (OAB. The objective of this study to compare the short-term success rates of STING and Double-HIT techniques in children with OAB-VUR complex. Materials and Methods Children who underwent endoscopic injection for VUR between 2010 and 2013 were retrospectively evaluated. Patients were grouped into two groups according to the surgical techniques (STING or Double-HIT. Success of the treatment was defined with a negative voiding cystourethrogram at the 6th postoperative week. Patients were evaluated according to sex, age, pre- and postoperative reflux grades, laterality, type and volume of bulking agent and presence of OAB. Results Both groups were similar in terms of sex, age, lower urinary tract dysfunction, reflux grade and success rates. Surgical technique, score of pediatric lower urinary tract symptom questionnaire, age, sex, laterality of reflux and type of the bulking agent found to have no effect on the overall success rates (p>0.05. Presence of OAB and/or a high grade reflux were identified as statistically significant predictive factors that could affect the treatment results. Conclusion The short-term surgical success of the double-HIT and STING techniques showed no difference in children with OAB. The presence of a high grade reflux and/or OAB seemed to be the main factors for overall success in endoscopic VUR surgery.

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

    To evaluate the effectiveness of endoscopic submucosal dissection using an insulation-tipped diathermic knife (IT-ESD) for the treatment of patients with gastric remnant cancer. Thirty-two patients with early gastric cancer in the remnant stomach, who underwent distal gastrectomy due to gastric carcinoma, were treated with endoscopic mucosal resection (EMR) or ESD at Sumitomo Besshi Hospital and Shikoku Cancer Center in the 10-year period from January 1998 to December 2007, including 17 patients treated with IT-ESD. Retrospectively, patient backgrounds, the one-piece resection rate, complete resection (CR) rate, operation time, bleeding rate, and perforation rate were compared between patients treated with conventional EMR and those treated with IT-ESD. The CR rate (40% in the EMR group vs 82% in the IT-ESD group) was significantly higher in the IT-ESD group than in the EMR group; however, the operation time was significantly longer for the IT-ESD group (57.6 +/- 31.9 min vs 21.1 +/- 12.2 min). No significant differences were found in the rate of underlying cardiopulmonary disease (IT-ESD group, 12% vs EMR group, 13%), one-piece resection rate (100% vs 73%), bleeding rate (18% vs 6.7%), and perforation rate (0% vs 0%) between the two groups. IT-ESD appears to be an effective treatment for gastric remnant cancer post distal gastrectomy because of its high CR rate. It is useful for histological confirmation of successful treatment. The long-term outcome needs to be evaluated in the future.

    To evaluate the effectiveness of improved sengstaken-blackmore tube combined with intensive endoscopic detachable mini-loop ligation for the treatment of massive esophageal variceal bleeding (EVB). Eighty-three patients diagnosed with massive EVB and admitted from January 2005 to July 2011 were retrospectively evaluated. Upon admission, all patients received 12 h balloon tamponade with sengstaken-blackmore tube in addition to conventional therapy (blood volume resuscitation, prophylactic antibiotics and somatostatin). Within 24 h after admission, all patients further received endoscopic variceal ligation (EVL) with intensive endoscopic detachable nylon ring (mini-loop). No severe complications were observed after the patients received the 12 h consistent compression with sengstaken-blackmore tube. Eighty-two patients (98.8%) showed effective hemostasis, among which seventy-eight showed complete hemostasis. After receiving the subsequent EVL therapy with intensive endoscopic detachable mini-loop in 24 h after admission, patients did not show active bleeding in 24 h after EVL. Rehaemorrhagia appeared only in one patient within the 7 days of observation period, which was controlled by a second EVL. Each patient was ligated with 10 to 15 loops. EVB can be effectively treated with improved sengstaken-blackmore tube followed by EVL therapy with intensive endoscopic detachable mini-loop.

    1997-08-01

    To measure the effects of different working instruments and holmium laser fibers on the deflectability in a variety of actively deflectable flexible endoscopes, a benchtop study was performed. The endoscopes studied were the Storz 7.5 flexible ureteroscope, the AUR-7 and AUR-9 flexible ureteroscopes (Circon-ACMI), a prototype Mitsubishi flexible ureteroscope (Mitsubishi Optics, Inc.), the ACN flexible cystoscope (Circon-ACMI), and the Storz flexible cystoscope. Working instruments included 1.6F (Wolf) and 1.9F (Microvasive) electrohydraulic lithotripsy (EHL) probes, 1.9F two-prong graspers and Bagley baskets, 2.4F Segura and helical baskets (Microvasive), 3.0F Segura basket, and 200- and 365-micron holmium laser fibers (Xintec). In ureteroscopes, the effect of 1.6F and 1.9F EHL probes ranged from having no effect in the Xintec 6,000, to decreasing deflection by 30 degrees in the AUR-7. Working instruments that were 2.4F or greater reduced deflection from 33 degrees to 93 degrees. Better deflectability was noted with the 200-micron holmium laser fiber than with the 365-micron fiber. The diameter of the working instrument did not affect deflectability as severely in cystoscopes. No significant differences in deflection existed between the 365-micron and 200-micron fibers in the flexible nephroscopes tested. In general, working instruments less than 2.4F and the 200-micron laser fiber have little effect on deflectability compared with working instruments 2.4F or larger and the 365-micron fiber. Flexible cystoscopes, with their larger working channels and stronger deflection cables, are affected less by working instrument diameter than are flexible ureteroscopes.

    To determine whether professional and amateur athletes showed differences in ankle function when treated with endoscopic technique for posterior ankle impingement syndrome, to verify the impact of the presence of associated lesions in clinical evolution and to assess time to return to sport (we hypothesize that time will be the only difference between groups). Thirty-two athletes with a diagnosis of posterior impingement syndrome underwent surgery endoscopically. The American Orthopaedics Foot and Ankle Society (AOFAS) scale was used to compare functional results between amateur (15) and professional athletes (17). The satisfaction, time to return to sport, operative time, intraoperative findings and complications were evaluated, and the presence of associated injuries interfering in these results was verified. The preoperative AOFAS score range for the professional group was 62.9 ± 14 preoperatively and 92.3 ± 7.7 postoperatively, and for the amateur group was 67.9 ± 19.7 and 94 ± 9.3. The satisfaction was excellent or good in 94 % of all cases and fair in 6%. The average time of surgery was 48.3 + 25 min. Bone involvement was present in 100% of cases and complications in three cases. Time to return to sports was similar (n.s.) in both groups, and the mean time was 15.6 ± 13.7 and 16.3 ± 9 weeks, respectively. No significant difference regarding functional results and time to return to sports between professionals and amateur athletes operated was found. Athletes showed mainly good and excellent results and low complication rate. The presence of associated injuries did not significantly influence the results. With these results, the high-level athlete can better programme their surgeries so they can fully recover and perform better in the most important competitions. Level III.

    Trigeminal schwannomas are the most common intracranial nonvestibular schwannomas, and the dumbbell-shaped subtype is the most challenging. To evaluate the efficiency and safety of the endoscope-assisted retrosigmoid intradural suprameatal approach (EA-RISA) for dumbbell trigeminal schwannomas and to compare EA-RISA with classic RISA. A retrospective study of all patients with trigeminal schwannomas was performed with a focus on dumbbell tumors. Tumors were classified according to a modified Samii classification. Extent of tumor removal, outcome, and morbidity rates in the 2 subgroups were compared. Twenty patients were enrolled: 8 had dumbbell-shaped tumors (type C1), 8 had middle fossa tumors (A1-3), 3 had extracranial extension (D2), and 1 had posterior fossa tumor. Gross total resection was achieved in 15 and near-total resection in 5 patients. In 4 patients with dumbbell tumors, the classic RISA (Samii approach) was used; EA-RISA was used in the other 4 patients. The extent of petrous apex drilling was determined individually on the basis of the anatomic variability of suprameatal tubercle and degree of tumor-induced petrous apex erosion; in 2 patients, only minimal drilling was needed. The endoscope was applied after microsurgical tumor removal and in 3 of 4 patients revealed a significant unrecognized tumor remnant in the anterolateral and superolateral aspects of the Meckel cave. Thus, the EA-RISA technique allowed gross total resection of the tumor. The EA-RISA enlarges the exposure obtained with the classic RISA. Its judicious use can help achieve safe and radical removal of dumbbell-shaped trigeminal schwannomas (C1 type).

    To determine the current preferred injection technique(s) for endoscopic management of pediatric vesicoureteral reflux (VUR). Since the approval of dextranomer hyaluronic acid copolymer (Dx/HA) in 2001, injection methods have evolved and now include the hydrodistention implantation technique (HIT) and double HIT as well as subureteral transurethral injection (STING) method. In July 2012, 278 pediatric urologists in the United States were contacted to complete a 15-question survey regarding Dx/HA injection technique(s) currently used in their practice. Fifty board-certified pediatric urologists completed the survey for a response rate of 18%. Most respondents (60%) were in a single-specialty group practice, and 12% were affiliated with an academic- or university-based practice. Respondents reported seeing a mean of 159 pediatric patients (range, 40-400 patients) with VUR annually, and 94% used Dx/HA ≥4 times in the past year. Forty-seven respondents (94%) reported using double HIT over the course of their career compared with 36 (72%) for STING and 30 (60%) for HIT (P injection techniques. A significantly higher percentage currently perform double HIT (92%) compared with either STING (24%) or HIT (34%; P <.001). Respondents reported the use of double HIT 15 times more often than STING technique and 5 times more often than HIT during the past 12 months (P <.001). The double HIT method is currently the most commonly performed technique for endoscopic correction of VUR by pediatric urologists in the United States. Copyright © 2014 Elsevier Inc.

    Endoscopic therapy is the principal method of treatment for esophageal varices. The recurrence of varices is still common following endoscopic treatment. The aim was to identify predictive factors for variceal recurrence detected by endosonography. We performed a systematic review of studies published prior to June 2013. Studies analyzing gastroesophageal collateral veins as risk factors for variceal recurrence after endoscopic treatment were included. The primary outcome was to identify predictive factors for variceal recurrence investigated by endosonography. After a full-text review, 13 studies were included in our analysis. Analysis of risk factors was not possible for all studies included. Perforating veins and periesophageal collateral veins were related to a higher risk of variceal recurrence (OR = 3.93; 95 % CI 1.06-14.51; I (2) = 96 %; OR = 2.29; 95 % CI 1.58-3.33; I (2) = 55 %). Analysis of cardiac intramural veins and paragastric/cardiac collateral veins showed the same trend, but without reaching statistical significance because of the small group size and wide CI (OR = 3.72; 95 % CI 0.14-101.53; I (2) = 91 %; OR = 1.85; 95 % CI 0.84-4.07; I (2) = 0 %). Analysis of other collateral veins as risk factors for variceal recurrence and analysis of risk factors with regard to the endoscopic treatment method was not possible because of the limited number of cases and different methodologies. A positive association between variceal recurrence and type and grade of collateral veins, investigated by endosonography, was demonstrated. Endosonography is a promising tool for predicting recurrence of esophageal varices following endoscopic treatment. These findings should be interpreted with caution because of the heterogeneity of the studies.

    Following an increasing number of submissions on endoscopic treatment of vesicoureteral reflux (VUR), the Journal of Pediatric Urology sought to establish a quality guideline that would enable reviewers to select the best papers for publication in the journal. The "Strengthening the Reporting of Observational Studies in Epidemiology" (STROBE) Statement, established in 2007, is a 22-item checklist designed to assist with clear reporting of observational studies. This checklist includes a description of methodological items and instructions on how to use them to transparently report observational studies. The aim of the present study was to apply the STROBE principle to observational studies about endoscopic management of VUR, and to establish a "check-list" to assist authors with good-quality submissions. The 22 STROBE criteria were listed and applied to publications on endoscopic treatment by utilizing examples from the current literature, with additional suggestions about how future studies could build upon the information already published on the subject. Based on this strategy, a checklist that is particular to endoscopic treatment studies was produced as a guideline for authors and reviewers. Application of the STROBE statement principles, in combination with key VUR data, will allow better quality submissions and a higher chance of positive reviews and acceptance rates.

    Full Text Available INTRODUCTION Chronic pain abdomen and dyspepsia is the most common presenting symptoms in the Paediatric Outpatient Department (OPD after respiratory illnesses. It is increasing alarmingly both in the paediatric and adult population. We, therefore carried out a cross-sectional study among children with chronic dyspepsia aged between 5 to 15 years attending Paediatric OPD in a rural medical college hospital, Melmaruvathur, Tamilnadu, South India. OBJECTIVE To evaluate the gastroduodenal morbidity in children presenting to the paediatric department of a rural medical college hospital with chronic dyspeptic symptoms. METHODS Forty six children between the age group of 5 to 15 years with chronic dyspeptic symptoms of at least one month duration were evaluated for their symptom profile, epidemiological profile, nutritional status, endoscopic appearance and histopathological changes. Data analysis was done using SPSS version 18. RESULTS Of the 46 children studied, 43% were between the age group of 5-10 years and 70% were female children. Pain abdomen lasting for more than at least one month was the most common finding (93% observed. Other common symptoms in the order of decreasing frequency were early satiety (87%, poor appetite (76%, nausea (57% and not thriving (57%. History of loss of appetite was significantly associated with chronic dyspepsia with an odds ratio of 68.9394 and 95% confidence interval 26.62 to 178.54, p value of <0.0001. Most of the children belonged to lower income group predominantly of a rural background. 33 (72% children had under nutrition as per IAP classification. 10 (30% Grade I, 15 (45% Grade II and eight (24% had Grade III malnutrition. 26 children (57% had abnormal endoscopic findings. Antral mucosal biopsy done showed chronic lymphocytic gastritis in 44 (96% cases. 38 of these 44 (86% were H. pylori positive. H. pylori positivity in chronic dyspepsia was highly statistically significant with a p value of 0

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

    Superficial esophageal neoplasias resected in piecemeal manner with endoscopic mucosal resection (EMR) sometimes recur locally, and additional treatments need to be developed. Efficacy and safety of endoscopic submucosal dissection (ESD) for esophageal neoplasias are not sufficiently demonstrated, so we conducted a retrospective study to evaluate the efficacy and safety of ESD for superficial esophageal neoplasias. Thirty-seven superficial esophageal neoplasias consisted of 34 squamous cell neoplasias and 3 columnar neoplasias in 35 patients were treated with ESD from May 2006 to July 2008. Patients were regularly followed up with endoscopy every 6 months, and with echoendoscope and computed tomography every year. Therapeutic efficacy, complications, and follow-up results were evaluated. The mean size of the resected neoplasias and that of the resected specimens were 22 mm (range 10-83 mm) and 41 mm (range 18-90 mm), respectively. The mean duration of the ESD procedures was 117 min (range 40-235 min). The overall rates of en bloc resection and of free margin resection were 100% (37/37) and 95% (35/37), respectively. The mean follow-up period of 19 months (range 7-32 months) revealed no local or distant recurrence. There were no complications such as bleeding or perforation in any case. In all nine cases, the strictures were successfully managed with prophylactic endoscopic balloon dilation. ESD with a combination of small-caliber-tip transparent hood and flex knife is a safe endoscopic treatment for superficial esophageal neoplasias and enables large en bloc resection.

    We have developed a regenerative medicine therapy for the alveolar bone and endoscopic surgery for maxillary sinus lift without bone grafts, in patients experiencing severe periodontal disease with significant absorption of the maxillary alveolar bone, in which more than 10 mm of bone thickness in the maxillary bone was attained, with satisfactory results. The objective of this study was to examine the treatment outcomes of implants that were performed after these therapies. The participants were 36 patients with severe periodontal disease, who cannot be cured with any other treatments except the extirpation of all teeth. The 36 patients are all patients who underwent regenerative treatment of the alveolar bone through tooth replantation and transplantation of the iliac cancellous bone (the bone marrow) as well as endoscopic surgery for maxillary sinus lift from May 2003 to July 2007 in our clinic. A total of 120 implants were placed in these patients when the replanted teeth fell out because of root resorption, and the success rate was examined. The success rates of the implants were 16 of 33 (48%) in the group when surveyed less than 2 years after the surgery and 84 of 87 (96.5%) in the group when surveyed more than 2 years after the surgery. A statistically significant difference was found between the 2 groups (Chi-squared test, P implant placement. Therefore, although the implant treatment should be performed later than 2 years after surgery, chewing is possible during this period, with the replanted teeth that were used for regenerative treatment of the alveolar bone. It is believed that this is an extremely effective treatment method to improve the patients' quality of life.

    In 1995, PDT was approved for palliative use in patients with esophageal cancer. We report our experience using PDT to treat esophageal cancer patients previously treated with combination chemotherapy and radiation therapy. In our series, nine patients referred for PDT with persistent esophageal cancer after chemo-radiation therapy. We found: (1) All patients were men with a mean age of 63 years and eight out of nine had adenocarcinoma with Barrett's esophagus; (2) All patients required endoscopic dilation after PDT; (3) At a mean follow up of 4 months, two T2N0 patients had no demonstrable tumor and all three T3N0 patients had greater than 50% tumor reduction (the partially responsive T3N0 patients will be offered repeat PDT); (4) Patients with metastatic disease (T3N1 or M1) had effective dysphagia palliation. Thus, PDT is safe and effective in ablating all or most tumor in patients with persistent esophageal cancer after chemotherapy and radiation therapy.

    The primary vesicoureteral reflux (PVUR) is the most common urologic pathology during childhood and affects from 1 to 3% of newborn. It causes acute pyelonephritis (APN) and renal damage in addition to hospital visits with high economic and social costs. Nowadays the endoscopic treatment (ETR) seems to be the most suitable one for the reflux, due to its lower biological cost and its good results. We report our experience in the endoscopic treatment of the primary vesicoureteral reflux (ETR) in Murcia Pediatric Hospital from 1998 to 2007. We present a retrospective study describing 989 patients (1498 ureters) treated by means of ETR. All patients were treated with chemoprophylaxis since the moment of the diagnosis. ETR was fulfilled by the surgeon in an ambulatory way and with Sevofluorano. Deflux, Macroplastique and Coaptite were used. Age, stade, number of ETR, material, chemoprophylaxis, ureterocistoneostomy and ETR costs were evaluated. One-thousand four-hundred and ninty-eight ureteral units, corresponding to 989 patients, (51,2% males), at ages from 4 months to 21-years-old, have been treated by means of ETR. The average age was 4-years-old. Grade III reflux was the most common of all, with 801 ureters affected. Deflux was used in 777 patients, Macroplastique in 203 and Coaptite in 9. No problems in early post-operation happened and the average length was shorter than 2 hours. Forty-eight hours after, 7 patients had to be treated due to APN. Four patients showed late litiasis related to ETR. Two suffered litotomy. The 89.9% of the patients were cured at first ETR. The 11.2% needed a second ETR, with 2.12% of failure (21 patients). Six cured with the third injection and 2 needed a fourth ETR. Thirteen children were treated with ureterocistoneostomy. Radiological correction have not relation with PVUR level and does not show significant differences. Failure regarding the used material was around 9% for Deflux, 11.8% for Macroplastique and 66.6% for Coaptite. The

    In recent years the endoscopic injection of dextranomer/hyaluronic acid has become an established alternative to long-term antibiotic prophylaxis and the surgical management of vesicoureteral reflux. We determined the safety and effectiveness of the endoscopic injection of dextranomer/hyaluronic acid as first line treatment for high grade vesicoureteral reflux. Between 2001 and 2010, 1,551 children (496 male, 1,055 female, median age 1.6 years) underwent endoscopic correction of intermediate and high grade vesicoureteral reflux using dextranomer/hyaluronic acid soon after the diagnosis of vesicoureteral reflux on initial voiding cystourethrogram. Vesicoureteral reflux was unilateral in 761 children and bilateral in 790. Renal scarring was detected in 369 (26.7%) of the 1,384 patients who underwent dimercapto-succinic acid imaging. Reflux grade in the 2,341 ureters was II in 98 (4.2%), III in 1,340 (57.3%), IV in 818 (34.9%) and V in 85 (3.6%). Followup ultrasound and voiding cystourethrogram were performed 3 months after the outpatient procedure, and renal ultrasound was performed annually thereafter. Patients were followed for 3 months to 10 years (median 5.6 years). Vesicoureteral reflux resolved after the first, second and third endoscopic injection of dextranomer/hyaluronic acid in 2,039 (87.1%), 264 (11.3%) and 38 (1.6%) ureters, respectively. Febrile urinary tract infections developed during followup in 69 (4.6%) patients. None of the patients in the series needed reimplantation of ureters or experienced any significant complications. Our results confirm the safety and efficacy of the endoscopic injection of dextranomer/hyaluronic acid in the eradication of high grade vesicoureteral reflux. We recommend this 15-minute outpatient procedure as the first line of treatment for high grade vesicoureteral reflux. Copyright © 2012 American Urological Association Education and Research, Inc.

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

    To evaluate the effectiveness of endoscopic submucosal dissection using an insulation-tipped diathermic knife (IT-ESD) for the treatment of patients with over 20 mm early gastric cancer (EGC). A total of 112 patients with over 10 mm EGC were treated with IT-ESD at Sumitomo Besshi Hospital and Shikoku Cancer Center in the 5 year period from January 2002 to December 2006, including 40 patients with over 20 mm EGC. We compared patient backgrounds, the one-piece resection rate, complete resection (CR) rate, operation time, bleeding rate, perforation rate between patients with over 20 mm EGC [over 20 mm group (21-40 mm)] and the remaining patients (under 20 mm group). We found no significant difference in the rate of underlying cardiopulmonary disease (over 20 mm group vs under 20 mm group, 5.0% vs 5.6%), one-piece resection rate (95% vs 96%), CR rate (85% vs 89%), operation time (72.3 min vs 66.5 min), bleeding rate (5% vs 4.2%), and perforation rate (0% vs 1.4%) between the 2 groups. Three patients in each group had submucosal invasion and two in each groups underwent additional surgery. There was no significant difference in the outcome resulting from IT-ESD between the 2 groups. Our study proves that IT-ESD is a feasible treatment for patients with over 20 mm mucosal gastric cancer although the long-term outcome should be evaluated in the future.

    The modalities of local and minimally invasive treatment were described for early rectal adenocarcinomas. The most adequate diagnostic studies and interdisciplinary interactions involved were considered in the process and the therapeutic results, in comparison with the current radical treatments. The historical evolution of the different surgical techniques developed over time, and the anatomical and physiological concepts were reviewed. The epidemiological behavior of the disease was documented according to gender, age and most prevalent sites to direct the possible risk groups to suffer the disease. Risk factors that affect patients with colorectal cancer were identified and related to the environment, social habits and hereditary. The different genetic syndromes involved in colorectal cancer, its physiopathology and clinical manifestations and implications were examined with respect to colorectal cancer. Colorectal cancer was defined according to the updated classifications of the American Joint Cancer Committee, according to the depth, affectation of lymph nodes and metastasis to distant organs, in relation to its clinical stage. Current surgical techniques were named to treat early adenocarcinomas of inferior rectus. The different risk factors were analyzed to allow local resections of the early rectal tumors, from the histopalogical, radiological and clinical point of view. The traditional techniques of transanal and radical resection were compared against the transanal endoscopic microsurgery between different aspects such as technical difficulty, recurrence rate, morbidity and mortality, and economic cost [es

    Single-stage management of CBD stones comprises simultaneous common bile duct (CBD) clearance and cholecystectomy. The CBD can be cleared by using endoscopic treatment (ET) or laparoscopic surgery (LS) alone. To determine the most rapid recovery after the single-stage laparoscopic management of CBD stones. Patients with CBD stones treated at either of two centers (one performing ET only and one performing LS only for single-stage treatment) were included. The primary endpoint was "the textbook outcome". The feasibility rate was 74% for ET and 100% for LS (p≤0.001). The proportion of cases with the textbook outcome was higher in the ET group than in the LS-only group (73% vs. 10%; pCBD clearance rate was similar in the ET and LS-only groups (100% vs. 96.6%, respectively; p=0.17). The overall morbidity rate was lower in the ET group than in the LS-only group (23% vs. 29%, p=0.05). Both ET and LS are feasible, safe and effective for clearance of the CBD. ET was better than LS in terms of a less frequent requirement for drainage and a shorter length of hospital stay. LS was associated with a shorter operating time.

    Endoscopic subureteral injection of dextranomer/hyaluronic acid has become an established alternative to long-term antibiotic prophylaxis or surgical treatment for vesicoureteral reflux. We evaluated the effectiveness of endoscopic injection of dextranomer/hyaluronic acid in intermediate and high grade vesicoureteral reflux in patients with complete duplex collecting systems. A total of 123 children underwent endoscopic correction of intermediate or high grade vesicoureteral reflux using injection of dextranomer/hyaluronic acid into complete duplex systems between 2001 and 2010. Vesicoureteral reflux was diagnosed by voiding cystourethrogram, and dimercapto-succinic acid scan was performed to evaluate the presence of renal scarring. Followup ultrasound and voiding cystourethrogram were performed 3 months after the outpatient procedure and renal ultrasound thereafter every 2 years. Mean followup was 6.7 years. Complete duplex systems were unilateral in 110 patients and bilateral in 13. Reflux severity in the 136 refluxing units was grade II in 1 (0.7%), III in 52 (38.2%), IV in 61 (44.9%) and V in 22 (16.2%). Dimercapto-succinic acid scan revealed renal functional abnormalities in 63 children (51.2%). Vesicoureteral reflux resolved after the first endoscopic injection of dextranomer/hyaluronic acid in 93 ureters (68.4%), after a second injection in 35 (25.7%) and after a third injection in 8 (5.9%). Febrile urinary tract infection developed in 5 patients (4.1%) during followup. No patient required ureteral reimplantation or experienced significant complications. Our results confirm the safety and efficacy of endoscopic injection of dextranomer/hyaluronic acid in eradicating intermediate and high grade vesicoureteral reflux in patients with complete duplex systems. We recommend this minimally invasive, 15-minute outpatient procedure as a viable option for treating intermediate and high grade vesicoureteral reflux in patients with complete duplex collecting systems

    Proton pump inhibitors are effective for the treatment of gastric ulcers after endoscopic submucosal dissection (ESD). However, the most excellent therapy is controversial. Vonoprazan, an active potassium-competitive acid blocker, has a strong gastric acid secretion inhibitory effect, but its efficacy for the treatment of post-ESD gastric ulcers is unclear. Herein, we aimed to determine the healing effect of vonoprazan on post-ESD gastric ulcers. We carried out a prospective randomized controlled trial examining 92 patients who had undergone ESD for the treatment of gastric neoplasms between April 2015 and June 2016 at Machida Municipal Hospital. Patients were treated with 20 mg/day vonoprazan (V group) or 20 mg/day esomeprazole (E group) for 8 weeks. We evaluated the 8-week cure rate for artificial ulcers and any complications after ESD. A total of 80 patients (median age, 73.5 years; 71.3% male) were analyzed. Cure rate for the V group was significantly higher than that for the E group (94.9% [37/39] vs 78.0% [32/41], respectively; P = 0.049). In a multivariate analysis, only vonoprazan was correlated with ulcer healing (odds ratio = 6.33; 95% CI = 1.21-33.20; P = 0.029). Delayed bleeding was experienced only in the E group (7.3% [3/41]), but no significant difference compared with the V group was observed (P = 0.241). Vonoprazan was significantly superior to esomeprazole for the healing of post-ESD gastric ulcers and should be considered as a treatment of first choice. © 2017 Japan Gastroenterological Endoscopy Society.

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

    We aimed at evaluating the efficacy and complications of two bulking substances: dextranomer/hyaluronic acid copolymer(Dx/Ha;Dexell®) versus polyacrylate polyalcohol copolymer(PPC;Vantris®) in subureteric injection treatment of children with high grades (grades IV-V) vesicoureteral reflux(VUR). Data of patients undergoing endoscopic treatment of high grade VUR (January 2009-August 2015) were retrospectively investigated. Patients with high grade VUR caused by posterior urethral valve, duplex system, paraureteral diverticula and neurogenic bladder were excluded. Classical subureteric injection method (STING) was used. Seventy-three children (45 girls and 28 boys) who had 88 refluxing renal units (RRUs) with grades IV-V VUR (n=64/n=24) underwent endoscopic treatment using Dx/Ha (n=63 RRUs) and PPC (n=25 RRUs). Mean age of patients in Dx/Ha and PPC groups were 6 (3) and 6 (3.75) year (p=0.81), and volumes of these substances given were 1.3 (1) and 1 (0.5) mL (p=0.003), respectively. Overall, for the first endoscopic injection, success rate of grades IV-V VUR per RRU was 53.9% with Dx/Ha, compared to 80% in PPC-injected group, (p=0.024). Late ureterovesical junction obstruction developed only in one patient in PPC-injected group. No ureteral obstruction was observed in Dx/Ha-injected group. Endoscopic injection of PPC resulted in significantly higher success rate, compared to Dx/Ha in subureteric injection treatment of children with high grade VUR. However, the development of late ureterovesical junction obstruction should also be taken into account in PPC injection. Copyright © 2016 Elsevier Inc. All rights reserved.

    Background A number of bulking agents have been used for the endoscopic correction of vesicoureteral reflux in children. We present our long-term results of endoscopic use of dextranomer/hyaluronic acid copolymer (Deflux®) for VUR treatment in children. Patients and methods Between 2004 and 2008, 21 children underwent endoscopic subureteral injection of Deflux® in 30 ureters as an outpatient procedure. Twelve children had unilateral reflux (2 duplicated systems) and nine had bilateral reflux. Median age was 5-years (6-months to 14.9-years). Six weeks postoperatively, a voiding cystourethrogram was performed. This study examined the disappearance of VUR and urinary tract infection (UTI) in the long-term follow-up as well as QoL (questionnaire of the parents). Results No intra- or postoperative complications had been noticed. In 25 ureters (83%), VCUG showed no VUR 6-weeks postoperatively. Three children received a 2nd injection (two successful). After a median follow-up of 2.5 years, 27 ureters in 17 children (90%) had no urinary tract infection and VUR. The questionnaire results in regard to quality of life (QoL) were very good in the successfully treated children and the parents would choose the same treatment option again. Conclusion Subureteral injection of Deflux® for children with VUR is an effective treatment option with a low complication rate. PMID:24578870

    Postoperative leaks are a dreaded complication after bariatric surgery (BS). Its treatment is based on nutritional support and sepsis control by antibiotics, collections drainage and/or prosthesis, and/or surgery. The aim of this study is to report our experience with coated self-expandable endoscopic stents (SEES) for leaks treatment. This study was performed in a University Hospital, (censored). We performed a retrospective analysis of our BS database from January 2007 to December 2013. All patients with leak after BS treated with SEES were included. We identified 29 patients; 17 (59%) were women, with median age of 37 (19-65) years, and preoperative body mass index of 40 (28.7-56-6) kg/m(2). Nineteen (65.5%) patients had a sleeve gastrectomy and 10 (34.5%) a Roux-en-Y gastric bypass. All patients had a leak in the stapler line. Median time from surgery to leak diagnosis was 7 (1-51) days, and SEES were installed 8 (0-104) days after diagnosis. Twenty-one (72%) patients also had abdominal exploration. Median length of SEES use was 60 (1-299) days. Patients who had SEES as primary treatment (with or without simultaneous reoperation) had a shorter leak closure time (50 [6-112] vs 109 [60-352] days; p = 0.008). Twenty-eight (96.5%) patients successfully achieved leak closure with SEES. There were 16 migrations in 10 (34%) patients, 1 (3%) stent fracture, 1 opening of the blind end of alimentary limb (3%), and 5 patients (17%) required a second stent due to leak persistence. SEES is a feasible, safe, and effective management of post BS leaks, although patients may also require prosthesis revision and abdominal exploration. Primary SEES placement is associated with a shorter leak resolution time.

    Endoscopic injection of dextranomer/hyaluronic is widely acknowledged as first-line treatment of lower grade vesicoureteral reflux. Our objective was to demonstrate its long-term efficacy and safety in eradicating high-grade reflux. Eight-hundred-fifty-one children (518 girls, 333 boys), median age 2.3 years (2 months-13.7 years), underwent endoscopic correction of high-grade vesicoureteral reflux using dextranomer/hyaluronic acid. Reflux was unilateral in 415 cases and bilateral in 436, comprising 1,287 refluxing units: grade IV in 1,153 (89.6%) and grade V in 134 (10.4%). 99m technetium-dimercaptosuccinic acid imaging identified renal scarring in 317 (37.3%) patients. Follow-up ultrasound and voiding cystourethrogram were performed 3 months post intervention and renal ultrasound annually thereafter. Median follow-up was 8.5 years (6 months-16 years). Overall resolution rate after the first endoscopic injection was 895/1,287 (69.5%): 70.4% in grade IV and 61.9% in grade V, respectively. Reflux resolved after a second injection in 259 (20.1%) and after a third in 133 (10.4%). Persistent reflux after initial treatment was significantly more common in infants injection of dextranomer/hyaluronic acid. Endoscopic injection of dextranomer/hyaluronic acid is an efficient and safe long-term treatment for grade IV and V vesicoureteral reflux, which can be easily repeated in cases of failure with a high subsequent resolution rate.

    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.

    The choice of appropriate treatment of discogenic low back pain (DLBP) frequently is difficult. This study sought to identify the clinical efficacy of percutaneous endoscopic lumbar annuloplasty and nucleoplasty (PELAN) to treat patients with DLBP and to investigate prognostic clinical or radiologic variables. Eighty-nine patients with a diagnosis of DLBP who underwent PELAN were included. Numeric Rating Scale (NRS) for back pain, Oswestry Disability Index % (ODI%), and modified Macnab criteria were measured at short-term (3-4 weeks) and long-term follow-up period (at least 12 months) to investigate clinical efficacy of PELAN. The subjects were defined as successful group in case of 50% or more reduction of NRS, 40% or more reduction of ODI%, and good or excellent response of Macnab criteria. Clinical and radiologic variables were compared between successful and unsuccessful outcomes group to determine prognostic variables. NRS and ODI% were significantly reduced at short- and long-term follow-up after PELAN. Sixty-two (69.7%) and 68 (76.4%) obtained successful NRS reduction and 59 (66.3%) and 68 (76.4%) accomplished successful ODI% reduction at short-term and long-term follow-up, respectively. Successful Mcnab response was found in 61% at short term and 65.2% at long term. Pain during waist flexion among clinical variables was significantly related to good clinical outcomes and Modic change among radiologic variables was significantly related to poor clinical outcomes. PELAN provided favorable outcomes in patients with DLBP who were refractory to conservative treatments. Flexion pain was good prognostic, and Modic change was a poor prognostic variable.

    Objective: To discuss the operational technique and clinical effect of metallic stent placement in treating malignant gastroduodenal obstruction. Methods: Metallic stent placement under fluoroscopic monitoring and endoscopic direct vision was performed in 47 patients with malignant gastroduodenal obstruction. A total of 54 metallic stents was used. Results: The procedure was successfully completed in all 47 patients. During the follow-up period, all the patients could take liquid or ordinary diet and were markedly relived of vomiting. The living quality was much improved and no serious complications occurred. Conclusion: Under fluoroscopic monitoring and endoscopic direct vision, stent placement is a safe, effective, technically-simple and time-saving procedure for the treatment of malignant gastroduodenal obstruction with less sufferings to the patient. Therefore, it is definitely worth popularizing this technique in clinical practice. (authors)

  7. A Case of Pseudoaneurysm of the Internal Carotid Artery Following Endoscopic Endonasal Pituitary Surgery: Endovascular Treatment with Flow-Diverting Stent Implantation

    2017-10-01

    Full Text Available Internal carotid artery (ICA pseudoaneurysm is a rare complication of endoscopic endonasal surgery occurring in 0.4–1.1% of cases. Pseudoaneurysms can subsequently result in other complications, such as subarachnoid hemorrhage, epistaxis, and caroticocavernous fistula with resultant death or permanent neurologic deficit. In this case, we illustrate endovascular treatment with a flow-diverting stent for an ICA pseudoaneurysm after endoscopic endonasal surgery for a pituitary adenoma in a 56-year-old male. Surgery was complicated by excessive intraoperative bleeding and emergent CT angiography confirmed an iatrogenic pseudoaneurysm on the anteromedial surface of the ICA. The pseudoaneurysm was treated endovascularly with flow-diverting stent implantation only. Follow-up CT angiography after three months demonstrated occlusion of the pseudoaneurysm.

    Transluminal retroperitoneal endoscopic necrosectomy (TREN) is an attractive NOTES technique alternative to surgery for treatment of walled-off pancreatic necrosis (WOPN). The main limitations to this technique are the need for repeated sessions, prolonged external irrigation, and EUS availability. In our study, we introduced new modifications, including the use of hydrogen peroxide, and abandoning the use of EUS and external irrigation. This is a retrospective study of outcome of consecutive patients who underwent TREN for WOPN between April 2011 and August 2012. The technique included (1) non-EUS-guided transluminal drainage, and (2) direct endoscopic debridement using hydrogen peroxide and different accessories. No external irrigation was used. Ten patients were included. Initial clinical and technical success was achieved in all patients. Complete radiological success and long-term clinical efficacy was achieved in nine patients (1 patient had an inaccessible left paracolic gutter collection and died 62 days after endotherapy). Mean number of sessions was 1.4 (range 1-2). Complications included bleeding, which was self-limited in three patients and endoscopically controlled in one. All patients avoided surgery, and no recurrence was reported during median follow-up of 289 (range 133-429) days. TREN is a safe and effective treatment for WOPN and could be performed safely without EUS guidance in selected cases. Hydrogen peroxide played a major role in reduction of number of sessions and timing. External irrigation of WOPN is not necessary, if adequate debridement could be achieved.

    Background The goals of medical intervention in patients with vesicoureteral reflux are to allow normal renal growth, prevent infections and pyelonephritis, and prevent renal failure. We present our experience with endoscopic treatment of vesicoureteral reflux in children by subureteral dextranomer/hyaluronic acid copolymer injection. Methods Under cystoscopic guidance, dextranomer/hyaluronic acid copolymer underneath the intravesical portion of the ureter in a subureteral or submucosal location was injected in patients undergoing endoscopic correction of vesicoureteral reflux. Results A total of 282 patients (120 boys and 162 girls) underwent the procedure. There were 396 refluxed ureters altogether. The mean age of patients was 4.9 years. The mean overall follow-up period was 44 months. Among the 396 ureters treated, 76% were cured with a single injection. A second and third injection raised the cure rate to 93% and 94%, respectively. Twenty-two (6%) ureters failed all 3 injections, and were converted to open surgery. Conclusion Endoscopic treatment of vesicoureteral reflux can be recommended as a first-line therapy for most cases of vesicoureteral reflux, because of the short hospital stay, absence of complications and the high success rate.

    Peroral endoscopic myotomy (POEM) is a recently introduced technique for the treatment of achalasia cardia (AC). Data regarding safety and efficacy are still emerging. We report our experience of POEM emphasizing its safety, efficacy and follow-up data. Patients with AC (220; mean age 39 years, range 9-74 years) underwent POEM from January 2013 to August 2014 for AC. Retrospective analysis of prospectively collected data was done. POEM was carried out by the standard technique of mucosal incision, submucosal tunneling, and myotomy of the esophageal and gastric muscle bundles followed by closure of the mucosal incision by hemoclips. Eckardt score, high-resolution manometry (HRM) and timed barium esophagogram (TBE) were used to evaluate the results. Post-procedure patients were followed up. Technical success rate of POEM was 96%. At 1 year, clinical success rate was 92%. Mean Eckardt score was 7.2 ± 1.55 prior to POEM and 1.18 ± 0.74 after POEM (P = 0.001). There was significant improvement of esophageal emptying on TBE (38.4 ± 14.0 % vs 71.5 ± 16.1 % (P = 0.001). Pre-procedure and post-procedure mean lower esophageal sphincter pressure was 37.5 ± 14.5 mmHg and 15.2 ± 6.3 mmHg, respectively. (P = 0.001) Erosive esophagitis was seen in 16% of patients who underwent POEM. There were no major adverse events. Study demonstrates excellent safety profile of POEM with significant relief of symptoms, reduced pressure at HRM and improved emptying at TBE. Further prospective studies are required to compare with other treatment modalities. © 2015 The Authors Digestive Endoscopy © 2015 Japan Gastroenterological Endoscopy Society.

    Ring complications after a banded Roux-en-Y gastric bypass (RYGB) are usually managed surgically. The aim of this study was to analyze the safety and effectiveness of endoscopic removal of noneroded rings after banded-RYGB, by inducing intragastric erosion of the ring using a self-expandable plastic stent (SEPS). A total of 41 patients with banded RYGB who had noneroded rings and food intolerance were prospectively enrolled. Patients were treated with endoscopic SEPS placement and ring removal. Data from time of stenting, resolution of symptoms, need for endoscopic dilation, and complications were recorded. Successful ring removal was possible in all patients. In 21 cases, the SEPS induced complete erosion, and in 17 cases the ring was removed a month later because of incomplete erosion at the time of SEPS removal. Nine patients (22.0 %) needed endoscopic dilation after stent removal in order to treat fibrotic strictures. Food tolerance was observed in 32 patients (78.0 %) after the procedure. No patient needed surgery and there were no deaths. Endoscopic removal of the ring using SEPS appeared to be safe and effective after a banded RYGB. © Georg Thieme Verlag KG Stuttgart · New York.

  12. Asymptomatic Esophageal Varices Should Be Endoscopically Treated

    Directory of Open Access Journals (Sweden)

    1998-01-01

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

    Congestive heart failure results in an increase in systemic venous pressure that is transmitted to the inferior vena cava and to the hepatic veins. This can cause GI vascular and mucosal congestion. The aim of this study was to define upper-GI mucosal changes in patients with congestive heart failure. A total of 57 patients with congestive heart failure presenting with GI symptoms underwent upper endoscopy. Echocardiography was performed in all patients to determine the ejection fraction and the degree of tricuspid regurgitation. Transabdominal US was performed to measure the diameters of the hepatic veins, the inferior vena cava, and the portal vein. The presence and the severity of gastropathy and duodenopathy were compared with the parameters relating to severity of cardiac failure. Of the 57 patients studied, gastric mucosal changes were observed in 50 (88%), duodenal mucosal changes in 31 (54%), and esophageal mucosal changes in none. Gastric mucosal changes were the following: mosaic-like pattern (n = 50), punctate spots (n = 34), thickened folds (n = 5), watermelon stomach (n = 3), and telangiectasia (n = 10). Duodenal mucosal changes were the following: mosaic-like pattern (n = 29), thickened folds (n = 8), and telangiectasia (n = 2). Upper-GI symptoms were associated with gastropathy ( p = 0.027) and duodenopathy ( p = 0.003). The presence and the severity of duodenopathy showed a high degree of positive correlation with the presence and the severity of gastropathy (gamma value 0.690; p value <0.001). Patients with gastropathy and duodenopathy had higher mean inferior vena cava and hepatic vein diameters than those without gastropathy and duodenopathy. The severity of duodenopathy but not that of gastropathy was significantly associated with increasing severity of tricuspid regurgitation ( p = 0.001), larger portal vein diameter ( p = 0.02), and lower ejection fraction ( p = 0.008). Among patients with congestive cardiac failure with GI symptoms, changes

    2017-07-01

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

    Here we report the results of a review of a prospectively maintained database of the use polyacrylate polyalcohol copolymer (PPC) injection to correct grades IV and V VUR. All children with grades IV and V primary VUR that presented with febrile urinary tract infection while on prophylaxis, in a 3-year period, were treated with a sub-ureteral injection of PPC. Institutional ethical approval was obtained. Exclusion criteria were incomplete bladder emptying documented on videourodynamic study, ureteral duplication, paraureteral diverticula, and poor ureteral emptying observed during fluoroscopy and previous open surgical or endoscopic treatment. Pre- and post-operative evaluation included urinalysis, renal and bladder ultrasonography, DMSA scan, and videourodynamic studies. Thirty-three children [36 renal units (RU)] were included with a median age of 57 months (range 7-108). There were 18 boys and 15 girls. Thirty RU had grade IV and 6 grade V VUR. Median follow-up time was 32 months (range 7-58). Reflux was cured in 32/36 RU with the first injection, but another two patients were reimplanted because of dilatation. Complications included early urinary tract infection in seven children, transient lower urinary tract symptoms in five children. Progressive ureteral dilatation was noted in four children and was treated with insertion of a double J stent. Two of these children eventually required an ureteroneocystostomy. The use of PPC to treat grades IV and V vesicoureteral reflux in young children has an overall success rate of 83.3%. Persistent ureteral dilatation was present in 11% associated with high injection volume. Future studies will attempt to maintain a high success rate reducing the volume of injection and the incidence of dilatation.

    Full Text Available Small bowel adenocarcinoma (SBA has generally been considered to have a poor prognosis because of nonspecific presentations and difficulties in detection of the disease. The advent of capsule endoscopy (CE and double-balloon endoscopy (DBE makes it possible to access to the small intestine for endoscopic interventions. We describe a successful case of early jejunum adenocarcinoma completely resected by endoscopic mucosal resection (EMR using double-balloon endoscopy (DBE. Early diagnosis and EMR using new technologies such as CE and DBE may improve the recognition of this disease that, at present, has a poor prognosis.

    Basal encephaloceles are rare, accounting for about 1.5% of all encephaloceles. The trans-sellar trans-sphenoidal encephalocele variety is the rarest. Morning glory syndrome is often associated with basal encephalocele. Spontaneous cerebrospinal fluid (CSF) rhinorrheas are the least common of these, accounting for only 3% to 5% of all CSF rhinorrheas. The authors describe the outcome of a 10-year follow-up study of a 26-year-old male patient with a spontaneous CSF rhinorrhea occurring trans-sphenoidal encephalocele associated with bilateral morning glory syndrome that was treated with an endoscopic endonasal approach. Endoscopic exploration of the sella floor was performed and closed with abdomen fat packing and muscle fascia. The postoperative course was uneventful. A follow-up magnetic resonance (MR) image at 6 months postoperatively showed extension of encephalocele in the sphenoidal sinus, which was repaired. The patient had no further CSF rhinorrhea and showed no ophthalmologic changes over a follow-up period of over 10 years. Ophthalmologic findings such as strabismus, in association with anomalies of the optic nerve, should alert the physician to the possible presence of an unrecognized skull base midline defect and encephalocele before CSF leakage is seen. The authors believe that a surgeon who has equal confidence in performing the endoscopic endonasal and conventional microscopic trans-sphenoidal approaches should choose the less invasive surgery.

    Per oral endoscopic myotomy (POEM) has recently emerged as a viable option relative to the classic approach of laparoscopic Heller myotomy (LHM) for the treatment of esophageal achalasia. In this cost-utility analysis of POEM and LHM, we hypothesized that POEM would be cost-effective relative to LHM. A stochastic cost-utility analysis of treatment for achalasia was performed to determine the cost-effectiveness of POEM relative to LHM. Costs were estimated from the provider perspective and obtained from our institution's cost-accounting database. The measure of effectiveness was quality-adjusted life years (QALYs) which were estimated from direct elicitation of utility using a visual analog scale. The primary outcome was the incremental cost-effectiveness ratio (ICER). Uncertainty was assessed by bootstrapping the sample and computing the cost-effectiveness acceptability curve (CEAC). Patients treated within an 11-year period (2004-2016) were recruited for participation (20 POEM, 21 LHM). During the index admission, the mean costs for POEM ($8630 ± $2653) and the mean costs for LHM ($7604 ± $2091) were not significantly different (P = 0.179). Additionally, mean QALYs for POEM (0.413 ± 0.248) were higher than that associated with LHM (0.357 ± 0.338), but this difference was also not statistically significant (P = 0.55). The ICER suggested that it would cost an additional $18,536 for each QALY gained using POEM. There was substantial uncertainty in the ICER; there was a 48.25% probability that POEM was cost-effective at the mean ICER. At a willingness-to-pay threshold of $100,000, there was a 68.31% probability that POEM was cost-effective relative to LHM. In the treatment of achalasia, POEM appears to be cost-effective relative to LHM depending on one's willingness-to-pay for an additional QALY.

    To demonstrate a new minimally invasive approach for the diagnosis and treatment of ectopic pregnancy. Stepwise explanation of the technique using original video footage. Hospital. Since 2014, 15 patients were treated transvaginally for ectopic pregnancy and pregnancy of unknown location (PUL). In case of a diagnosis of ectopic pregnancy on ultrasound, a 2.5-cm colpotomy is made under general anesthesia, and the ectopic pregnancy is treated by transvaginal natural orifice transluminal endoscopic surgery (vNOTES) salpingectomy or salpingostomy. In case of a PUL on ultrasound, transvaginal hydrolaparoscopy (TVHL), an established technique for fertility exploration under local or general anesthesia, is used to investigate. If a tubal pregnancy is confirmed on TVHL, the colpotomy is extended to a 2.5-cm incision, and the ectopic pregnancy is treated transvaginally by vNOTES. If the TVHL investigation of the pelvis is negative (fallopian tubes and ovaries are normal), the procedure is stopped and the patient is followed up further. If the TVHL is inconclusive, the NaCl is drained and CO 2 is insufflated (requiring general anesthesia) through the 4-mm TVHL port to improve visualization. Again, an ectopic pregnancy is then treated by vNOTES, and in case of a negative investigation the procedure is stopped and the patient is followed up further. Successful diagnosis and treatment of ectopic pregnancies. All patients were successfully operated without complications or conversions to standard laparoscopy. Twelve patients were treated by vNOTES for ectopic pregnancy. Three TVHL explorations for PUL were negative, and these patients were followed up; two patients developed a normal intrauterine pregnancy, and the third patient was treated with methotrexate for persistent asymptomatic raised hCG levels. Transvaginal hydrolaparoscopy and vNOTES are complementary techniques enabling gynecologic surgeons to explore PUL and treat ectopic pregnancies via minimally invasive

    Full Text Available Purpose: VUR is a common urologic problem in children. Cystoscopic injection of bulking agents (most commonly Deflux has gained popularity as the first line treatment in the west. However, primarily due to cost factors, it has not gained much popularity in our country. We present our initial experience with cystoscopic Deflux injection for VUR. Materials and Methods: We reviewed our 3-yr experience with the use of Dx/HA (Deflux for correction of VUR in children and adolescents. All children were evaluated with Ultrasound, MCUG and DMSA renal cortical scan. The indications for surgical correction of VUR included breakthrough infections while on antibiotic prophylaxis, persistent high-grade VUR beyond 3 yrs of age, and presence of significant renal damage on DMSA at diagnosis (in those children presenting with UTI. All children underwent cystoscopic Deflux injection using the standard technique of subureteral injection (0.4-1 ml per ureter. All children received antibiotic prophylaxis for 3-6 months after the injection. USG was done at 1 month and MCUG at 3-6 months after the injection. Results: 33 patients (48 ureters underwent cystoscopic Deflux injection for correction of VUR. Mean age was 4.5 yrs (1-17 yrs; there were 12 boys and 21 girls. Thirteen children had antenatally diagnosed HDN, while 20 children presented with febrile UTI. All children had primary VUR except one child with persistent VUR 4 yrs after PUV fulguration. The VUR was grade 1-2 in 8, grade 3-4 in 37, and grade 5 in 3 ureters. Every child had at least one ureter with dilating reflux (grades 3,4 or 5. When present, low grade VUR (grade 1or 2 was always on the contralateral side. Only one child received a 2 nd injection after 6 months. Follow-up MCUG was done in 28 children (41 ureters. Complete reflux resolution was achieved in 27 ureters (65%, and the reflux was downgraded in 2 (5%. There were no complications of Deflux injection. Conclusions: Endoscopic correction of VUR in

    Despite significant therapeutic progress in recent years, inflammatory bowel disease (IBD), which includes Crohn's disease and ulcerative colitis, remains a challenge regarding its pathogenesis and long-term complications. New concepts have emerged in the management of this disease, such as the "treat-to-target" concept, in which mucosal healing plays a key role in the evolution of IBD, the risk of recurrence and the need for surgery. Endoscopy is essential for the assessment of mucosal inflammation and plays a pivotal role in the analysis of mucosal healing in patients with IBD. Endoscopy is also essential in the detection of dysplasia and in the identification of the risk of colon cancer. The current surveillance strategy for dysplasia in IBD patients indicates white-light endoscopy with non-targeted biopsies. The new chromoendoscopy techniques provide substantial benefits for both clinicians and patients. Narrow-band imaging (NBI) has similar rates of dysplastic lesion detection as white-light endoscopy, and it seems that NBI identifies more adenoma-like lesions. Because it is used instinctively by many endoscopists, the combination of these two techniques might improve the rate of dysplasia detection. Flexible spectral imaging color enhancement can help differentiate dysplastic and non-dysplastic lesions and can also predict the risk of recurrence, which allows us to modulate the treatment to gain better control of the disease. The combination of non-invasive serum and stool biomarkers with endoscopy will improve the monitoring and limit the evolution of IBD because it enables the use of a personalized approach to each patient based on that patient's history and risk factors.

    To compare efficacy of Cohen's ureteral reimplantation and endoscopic treatment with Dx/HA in patients with primary VUR grades II, III and IV. From April 2002 to June 2004, patients over 1 year old with VUR grade I, II, III or IV were included. Patients were randomized into two groups: endoscopic treatment (ET) or ureteral reimplantation (UR). In the ET group, an ultrasonography study was performed 24 h and 1 month after surgery, and two voiding cystourethrographies at 3 and 6 months post treatment. In the UR group, an ultrasonography study was done 7 days and 1 month after surgery and a micturial cystography 6 months post surgery. A postoperative nuclear direct cystogram was performed 5 years later in both groups. A total of 41 patients were included in this study: in ET 22 patients with 35 refluxing ureters and in UR 19 patients with 32 refluxing ureters. The VUR grades in ET were: 16 grade II, 16 grade III and 3 grade IV; and in UR: 15 grade II, 12 grade III and 5 grade IV. VUR was resolved in 91% (32/35) of ET (28% of ureters needed a second injection), and in 100% of UR group. Five years after the procedure, VUR was still resolved in 30/32 of ET and 32/32 of UR. Short- and long-term follow up shows that multiple endoscopic treatment of VUR grades II, III and IV with Dx/HA is as effective as ureteral reimplantation.

    Effective urolithiasis treatment, especially in overweight patients has a considerable medical and social implication. Extracorporeal shock wave lithotripsy (ESWL) and percutaneous nephrolithotripsy (PCNL) in prone position of the patient are standard treatment options for kidney and ureter stones. These interventions are not always effective in patients with concomitant obesity and are associated with technical difficulties and an increased risk of complications. The study included 175 patients with obesity. The first group consisted of 96 (54.8%) patients treated with transurethral contact lithotripsy. The 2nd group consisted of 54 (30.9%) patients who underwent PCNL in the supine position. The third group comprised 25 (14.3%) patients with multiple stones of kidney and ureter, who underwent combined transurethral and percutaneous intervention in the supine position. The 1st and 3rd group had a higher prevalence of patients with II degree of obesity, in the 2nd group--with I degree of obesity. The mean duration of surgery in 1st group was 43.4 min, in the 2nd--70.3 min and in the third--84.6 min. Method of kidney drainage depended mainly on the presence, location and size of residual stone fragments. The average duration of the kidney drainage stent in patients of the 1st group was 39 days (ureteral catheter--1.3 days). In all patients of the 2nd and 3rd groups, at the final stage of the operation a nephrostomy tube was placed for an average of 2.7 days. The average postoperative hospital stay was 2.9 days in the 1st group, 4.1 days in the 2nd group and 4.5 days in the third group. In the 1st group, the stone-free status was achieved in 81 (84.4%) patients. Another 10 (10.4%) patients later needed ESWL for the complete disposal of the stones. In the 2nd group, the complete clearance of kidney stones was achieved in 49 (90.7%) patients. Another 3 (5.6%) patients required added ESWL to achieve the stone-free status. In the third group of patients stone free status

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

    The study describes the design and synthesis of an implantable smart magnetic nanofiber device for endoscopic hyperthermia treatment and tumor-triggered controlled drug release. This device is achieved using a two-component smart nanofiber matrix from monodisperse iron oxide nanoparticles (IONPs) as well as bortezomib (BTZ), a chemotherapeutic drug. The IONP-incorporated nanofiber matrix was developed by electrospinning a biocompatible and bioresorbable polymer, poly (d,l-lactide-co-glycolide) (PLGA), and tumor-triggered anticancer drug delivery is realized by exploiting mussel-inspired surface functionalization using 2-(3,4-dihydroxyphenyl)ethylamine (dopamine) to conjugate the borate-containing BTZ anticancer drug through a catechol metal binding in a pH-sensitive manner. Thus, an implantable smart magnetic nanofiber device can be exploited to both apply hyperthermia with an alternating magnetic field (AMF) and to achieve cancer cell-specific drug release to enable synergistic cancer therapy. These results confirm that the BTZ-loaded mussel-inspired magnetic nanofiber matrix (BTZ-MMNF) is highly beneficial not only due to the higher therapeutic efficacy and low toxicity towards normal cells but also, as a result of the availability of magnetic nanoparticles for repeated hyperthermia application and tumor-triggered controlled drug release. The current work report on the design and development of a smart nanoplatform responsive to a magnetic field to administer both hyperthermia and pH-dependent anticancer drug release for the synergistic anticancer treatment. The iron oxide nanoparticles (IONPs) incorporated nanofiber matrix was developed by electrospinning a biocompatible polymer, poly (d,l-lactide-co-glycolide) (PLGA), and tumor-triggered anticancer drug delivery is realized by surface functionalization using 2-(3,4-dihydroxyphenyl)ethylamine (dopamine) to conjugate the boratecontaining anticancer drug bortezomib through a catechol metal binding in a p

    This study aimed to assess whether endoscopic implantation of an injectable esophageal prosthesis, the Gatekeeper Reflux Repair System (GK), is a safe and effective therapy for controlling gastroesophageal reflux disease (GERD). A prospective, randomized, sham-controlled, single-blinded, international multicenter study planned final enrollment of 204 patients in three groups: up to 60 lead-in, 96 GK, and 48 sham patients. The sham patients were allowed to cross over to the GK treatment arm or exit the study at 6 months. The primary end points were (1) reduction in serious device- and procedure-related adverse device effects compared with a surgical composite complication rate and (2) reduction in heartburn symptoms 6 months after the GK procedure compared with the sham procedure. The secondary end point was improved esophageal pH (total time pH was <4) 6 months after the GK procedure compared with baseline. A planned interim analysis was performed after 143 patients were enrolled (25 lead-in, 75 GK, and 43 sham patients), and the GK study was terminated early due to lack of compelling efficacy data. Four reported serious adverse events had occurred (2 perforations, 1 pulmonary infiltrate related to a perforation, and 1 severe chest pain) at termination of the study with no mortality or long-term sequelae. Heartburn symptoms had improved significantly at 6 months compared with baseline in the GK group (p < 0.0001) and the sham group (p < 0.0001), but no significant between-group difference in improvement was observed (p = 0.146). Esophageal acid exposure had improved significantly at 6 months compared with baseline in the GK group (p = 0.021) and the sham group (p = 0.003), but no significant between-group difference in improvement was observed (p = 0.27). The GK procedure was associated with some serious but infrequent complications. No statistically significant difference in outcomes was observed between the treatment and control groups at 6 months compared with

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

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

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

    The topical antispasmodic agent l-menthol is useful for inhibiting gastric peristalsis during diagnostic upper gastrointestinal endoscopy. However, it remains unclear whether l-menthol is similarly effective during therapeutic endoscopy, thereby improving treatment outcomes in a clinical setting. A total of 83 patients scheduled to undergo endoscopic treatment at 8 Japanese referral centers were randomly assigned to receive l-menthol or placebo. The degree of gastric peristalsis (peristaltic score: grade 1-5) was assessed by an independent committee. The primary outcome was the proportion of subjects in whom no or mild peristalsis (grade 1 or 2) was maintained throughout endoscopic treatment. Secondary outcomes were the duration of sustained response and the incidence of adverse drug reactions. The proportion of patients with no or mild peristalsis was significantly higher in the l-menthol group (85.4 %, 95 % confidence intervals 70.8-94.4: 35/41 subjects) than in the placebo group (39.0 %, 24.2-55: 16/41; P peristalsis, with minimal adverse drug reactions as compared with placebo. l-menthol solution might be useful for therapeutic endoscopy.

    Full Text Available Objective: Robotic assisted pyeloplasty (RAP is rapidly adopted by surgeons around the world. We present a unique complication of the technique, consisting of pigtail misplacement, which was endoscopically resolved. We discuss the clinical findings, differential diagnosis and principles of endoscopic treatment. Materials and Methods: A 41 years old female patients underwent transperitoneal right side RAP with the Hynes-Anderson technique for ureteropelvic junction obstruction. Pigtail was placed intraoperatively in an antegrade fashion. Post operative course appeared normal but Kidney-Ureterer-Bladder(KUB X-ray, revealed a misplaced pigtail. Patient underwent a semirigid ureterorenoscopy demonstrating that the pigtail was exiting the collecting system in the rear line of suturing between continuous sutures. Pigtail was retrieved with a stone retrieval forceps with short upward motions in the renal pelvis under fluoroscopy and then removed from patient, in order to avoid stressing the anastomosis. No leakage was noted in fluoroscopy, a pigtail was correctly placed and patient recovery was uneventful. Results: Retrograde pyelography was the key to accurate diagnosis and endoscopic treatment, because the exact point of exit and anastomosis integrity were established. Retrieval of the pigtail was the most challenging part. Lack of proper visualization and mobilization of the rear part of the anastomosis during surgery, combined with lack of tactile feedback, because of robotic instrumentation, were of critical importance in the manifestation of such a mishap. Endoscopy facilitated case resolve, but proper handling is required to protect the anastomosis. Conclusions: The introduction of novel techniques can carry the burden of novel complications. A surgeon must always keep in mind the complications inherent to the technique and at the same time the limitations of the equipment used, especially the lack of tactile feedback in robotic instrumentation.

    Traditionally, Helicobacter infection is considered to be the most common cause of gastritis. In the cross-sectional Central European histoGERD trial, we assessed the prevalence of different types of gastritis, correlating histological and endoscopic diagnoses. A total of 1123 individuals participated in an observational multicentre study. Endoscopists classified individuals as positive or negative for gastritis and rendered the putative cause. Pathologists evaluated biopsy specimens based upon the Updated Sydney System. Histological diagnosis of gastritis was made in 639 (56.9%) participants. In all, 210 (18.7%) individuals were diagnosed with Helicobacter gastritis, 215 (19.1%) with post Helicobacter gastritis, 234 (20.8%) with reactive gastropathy, 26 (2.3%) with autoimmune gastritis, and 6 (0.5%) with focally enhanced gastritis related to Crohn's disease. In 46 out of 639 (7.2%) individuals diagnosed with gastritis, combinations of different histological subtypes were noted the most common being reactive gastropathy and post Helicobacter gastritis. Endoscopic diagnosis of gastritis was made in 534 (47.6%) individuals. Reactive gastropathy was more common than active Helicobacter gastritis, and the majority of cases attributable to Helicobacter infection were no longer ongoing, i.e. post Helicobacter gastritis. Agreement between histological and endoscopic diagnoses was better in reactive gastropathy than in Helicobacter gastritis. Copyright © 2014 Editrice Gastroenterologica Italiana S.r.l.

    The study was to comprehensively compare the postoperative outcome and imaging parameter characters in a short/middle period between the percutaneous endoscopic lumbar discectomy (PELD) and the internal fixation of bone graft fusion (the most common form is posterior lumbar interbody fusion [PLIF]) for the treatment of adjacent segment lumbar disc prolapse with stable retrolisthesis after a previous lumbar internal fixation surgery.In this retrospective case-control study, we collected the medical records from 11 patients who received PELD operation (defined as PELD group) for and from 13 patients who received the internal fixation of bone graft fusion of lumbar posterior vertebral lamina decompression (defined as control group) for the treatment of the lumbar disc prolapse combined with stable retrolisthesis at Department of Spine Surgery, the Third Hospital of Hebei Medical University (Shijiazhuang, China) from May 2010 to December 2015. The operation time, the bleeding volume of perioperation, and the rehabilitation days of postoperation were compared between 2 groups. Before and after surgery at different time points, ODI, VAS index, and imaging parameters (including Taillard index, inter-vertebral height, sagittal dislocation, and forward bending angle of lumbar vertebrae) were compared.The average operation time, the blooding volume, and the rehabilitation days of postoperation were significantly less in PELD than in control group. The ODI and VAS index in PELD group showed a significantly immediate improving on the same day after the surgery. However, Taillard index, intervertebral height, sagittal dislocation in control group showed an immediate improving after surgery, but no changes in PELD group till 12-month after surgery. The forward bending angle of lumbar vertebrae was significantly increased and decreased in PELD and in control group, respectively.PELD operation was superior in terms of operation time, bleeding volume, recovery period, and financial

    Abstract The study was to comprehensively compare the postoperative outcome and imaging parameter characters in a short/middle period between the percutaneous endoscopic lumbar discectomy (PELD) and the internal fixation of bone graft fusion (the most common form is posterior lumbar interbody fusion [PLIF]) for the treatment of adjacent segment lumbar disc prolapse with stable retrolisthesis after a previous lumbar internal fixation surgery. In this retrospective case-control study, we collected the medical records from 11 patients who received PELD operation (defined as PELD group) for and from 13 patients who received the internal fixation of bone graft fusion of lumbar posterior vertebral lamina decompression (defined as control group) for the treatment of the lumbar disc prolapse combined with stable retrolisthesis at Department of Spine Surgery, the Third Hospital of Hebei Medical University (Shijiazhuang, China) from May 2010 to December 2015. The operation time, the bleeding volume of perioperation, and the rehabilitation days of postoperation were compared between 2 groups. Before and after surgery at different time points, ODI, VAS index, and imaging parameters (including Taillard index, inter-vertebral height, sagittal dislocation, and forward bending angle of lumbar vertebrae) were compared. The average operation time, the blooding volume, and the rehabilitation days of postoperation were significantly less in PELD than in control group. The ODI and VAS index in PELD group showed a significantly immediate improving on the same day after the surgery. However, Taillard index, intervertebral height, sagittal dislocation in control group showed an immediate improving after surgery, but no changes in PELD group till 12-month after surgery. The forward bending angle of lumbar vertebrae was significantly increased and decreased in PELD and in control group, respectively. PELD operation was superior in terms of operation time, bleeding volume, recovery period

    The hypothesis that non-erosive reflux disease (NERD) patients comprise various subgroups is gaining popularity. This study was conducted to investigate the possibility of categorizing NERD patients according to symptom types and response to acid-suppressive drug rabeprazole (RPZ) 10 mg/day. NERD patients were classified as grade N (endoscopically normal), M (minimal change), or erosive GERD, and answered a 51-item, yes-or-no questionnaire pre and post-treatment. Compared to erosive GERD, clear differences existed in pretreatment prevalence of symptoms and responsiveness to RPZ in grades N and M; the results suggested stomachaches (especially at night) were significant symptoms in grade N and dysmotility-like symptoms like bloated stomach were significant in grade M while gastroesophageal reflux symptoms were significant in erosive GERD. Clinical significance of classifying NERD was indicated from different symptoms and responsiveness to PPI.

    To determine whether treatment outcome is associated with visualization of contrast extravasation in patients with acute massive gastrointestinal bleeding after endoscopic failure. From January 2007 to December 2009, patients that experienced a first attack of acute gastrointestinal bleeding after failure of initial endoscopy were referred to our interventional department for intra-arterial treatment. We enrolled 79 patients and divided them into two groups: positive and negative extravasation. For positive extravasation, patients were treated by coil embolization; and in negative extravasation, patients were treated with intra-arterial vasopressin infusion. The two groups were compared for clinical parameters, hemodynamics, laboratory findings, endoscopic characteristics, and mortality rates. Forty-eight patients had detectable contrast extravasation (positive extravasation), while 31 patients did not (negative extravasation). Fifty-six patients survived from this bleeding episode (overall clinical success rate, 71%). An elevation of hemoglobin level was observed in the both two groups; significantly greater in the positive extravasation group compared to the negative extravasation group. Although these patients were all at high risk of dying, the 90-day mortality rate was significantly lower in the positive extravasation than in the negative extravasation (20% versus 42%, p < 0.05). A multivariate analysis suggested that successful hemo stasis (odds ratio [OR] = 28.66) is the most important predictor affecting the mortality in the two groups of patients. Visualization of contrast extravasation on angiography usually can target the bleeding artery directly, resulting in a higher success rate to control of hemorrhage.

    Full Text Available IntroductionSymptomatic umbilical and/or epigastric hernias are often seen concomitantly with rectus abdominis diastasis (RAD, and suture repair of such defects has a high recurrence rate. In the literature there are reports of both endoscopic and open techniques for repair of symptomatic umbilical and/or epigastric hernias in association with RAD. This paper now reports on the early results of a hybrid technique used for reconstruction of the linea alba and mesh augmentation (ELAR plus.Material and methodsBetween 15 June 2015 and 31 January 2016, 40 patients with symptomatic umbilical and /or epigastric hernia and concomitant RAD underwent reconstruction of the linea alba using a hybrid technique involving a small umbilical incision and the use of video endoscopic equipment. The patients comprised 29 men and 11 women with a mean age of 53.6 years and mean BMI of 32.6. The mean operating time was 120 minutes. The mesh had a mean longitudinal extension of 18.6 cm and transverse extension of 9.1 cm. ResultsThirty-day follow-up results are available for all patients. Thirty-seven out of 40 patients (92.5 % experienced no postoperative complication. Two cases of discrete impaired umbilical wound healing and one seroma were successfully managed with conservative treatment. On 30-day follow-up, three out of 40 patients (7.5 % complained of intermittent pain on exertion, and two out of 40 patients (5 % still took painkillers when required.ConclusionEndoscopic-assisted linea alba reconstruction plus mesh augmentation (ELAR plus is a novel minimally invasive procedure for repair of symptomatic umbilical and/or epigastric hernias with concomitant RAD. Reconstruction of the linea alba via a minimally invasive access route is able to restore the normal anatomy of the abdominal wall.

    Some guidelines recommend an early voiding cystourethrography (VCUG) after endoscopic treatment of vesicoureteral reflux (VUR), but there's no consensus if it's necessary a long-term follow-up in these patients. The aim of our study is analyze if it's necessary a delayed VCUG after initial successful treatment with Dx/HA. We have reviewed all medical charts of patients that underwent Dx/HA treatment from 2006 to 2010. We have selected patients with initial successful treatment and more than 3 years of radiological and clinical follow-up. We have analyzed late clinical and radiological outcomes. One hundred and sixty children with 228 refluxing ureters underwent Dx/HA endoscopic treatment with a mean follow-up of 52.13 months. Early VCUG was performed in 215 ureters with an initial successful rate of 84.1%. The group of study was 94/215 ureters with more than 3 years of follow-up with a delayed VCUG. VUR was still resolved in 79,8% of the ureters. Clinical success rate was 91.7%. The incidence of febrile urinary tract infection in those patients with cured VUR and those with a relapsed VUR was 8 and 15%, respectively; but there were no significant differences. We have not found any variable related with relapsed VUR except those ureters that initially received 2 injections (P<.05). If our objective in the treatment of VUR is to reduce the incidence of febrile urinary tract infection it is not necessary to perform a delayed VCUG even though the long-term radiological outcomes is worse than clinical outcome.

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

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

    The study aimed to estimate the value of embryonal natural orifice transluminal endoscopic surgery (ENOTES) in treating severe acute pancreatitis (SAP) complicated with abdominal compartment syndrome (ACS). The patients, who were randomized into an ENOTES group and an operative group, underwent ENOTES and laparotomy, respectively. The results and complications of the two groups were compared. Enterocinesia was observed earlier in the ENOTES group than in the operative group. Acute Physiology and Chronic Health Evaluation II (APACHE II) score of patients in the ENOTES group was lower than that of the operative group on the 1st, 3rd and 5th post-operative day (Pcomplications and mortality between the two groups (Pcomplications.

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

    Per oral endoscopic myotomy (POEM) is increasingly utilized to treat patients with achalasia. Early results have demonstrated significant improvement of symptoms, but there are concerns about postoperative reflux. With only limited comparative data available, we sought to compare POEM to laparoscopic Heller myotomy (LHM) with partial fundoplication. This is a retrospective review of 42 POEM and 84 LHM patients undergoing primary myotomy for achalasia. Patients were matched by achalasia type, by Eckardt and dysphagia scores, and by quality of life (QOL) metrics. Analysis at 6-12-month follow-up evaluated these metrics, PPI use, pH, manometric, and endoscopic data. We matched 25 patients with achalasia types I (6), II (13), and III (6). Follow-up was longer for LHM at 158.1 (36.5-272.9) weeks versus 36.2 (22.2-41.2) weeks (p = 0.001). Eckardt scores, QOL metrics, and dysphagia significantly improved in both groups. DeMeester scores and total percent time less than 4 were abnormal in both groups and comparable (p = 0.925 and p = 0.838). Esophagitis was seen in 53.4 % (POEM) and 31.6 % (LHM) (Yates' p = 0.91), and PPI use was equivalent at 36 %. Early clinical outcomes are excellent with POEM and comparable to the standard of care LHM. Long-term follow-up is required as concerns for reflux persist.

    To investigate the impact of tissue glue on mast cells (MC) and epidermal growth factor receptor (EGFR) in rat peptic ulcer. SD rats were used to establish peptic ulcer model. Cimetidine gavage was adopted in the positive control, while cimetidine and endoscopic tissue glue therapy were applied in the experimental group. The ulcer inhibition rate and ulcer index were measured to evaluate healing quality. Real-time PCR was performed to test EGFR mRNA in the ulcer surrounded gastric mucosa. Immunohistochemistry was selected to determine MC quantity. HE staining and apoptosis detection were used to evaluate cell apoptosis. Tissue glue significantly reduced MC number in the peptic ulcer rat compared with control with dose dependence (p ulcer area, and elevated ulcer index and inhibition rate (p 0.05). Tissue glue induced MC apoptosis with dose dependence. Endoscopic application of tissue glue accelerated ulcer mucosa healing via up-regulating EGFR mRNA, enhancing gastrointestinal mucous membrane regeneration and repair ability, and decreasing MC number.

    Percutaneous endoscopic interlaminar discectomy (PEID), which poses advantages for certain types of herniated disc, is gaining wider acceptance in clinical practice. We retrospectively analyzed the efficacy of the PEID technique in treatment of calcified lumbar disc herniation. A retrospective case-control study. University hospital in China. To evaluate the efficacy of the PEID technique in treatment of calcified lumbar disc herniation, and a comparison between calcified and noncalcified disc herniation was drawn to analyze the causes of herniated disc calcification. Data from patients who underwent full-endoscopic lumbar discectomy in our department between March 2011 and May 2013 were collected. Thirty cases with calcified lumbar disc herniation were included in the study group, and 30 age-, gender-, and body mass index (BMI)-matched cases with noncalcified lumbar disc herniation served as controls. Perioperative data, preoperative and postoperative Visual Analog Scale (VAS) scores, Oswestry Disability Index (ODI) values, MacNab scores, and postoperative low-extremity dysesthesia among patients in the 2 groups were collected. The values of computed tomography (CT) in the calcified group were significantly higher than those in the noncalcified group (P 0.05). Three months after surgery, the rate of low-extremity dysesthesia in the calcified group was significantly higher than that in the control group (P = 0.03) but became similar at 6 months. By applying MacNab criteria the proportions of good and excellent were greater than 90% in both groups, and there was no difference between groups (P > 0.05). The sample size was small in this retrospective study. The PEID technique is an effective method in the treatment of calcified lumber disc herniation, although the rate of postoperative dysesthesia is higher in this group during the early postoperative period. Long-term TCM administration may be related to the calcification of herniated lumbar discs.

    Full Text Available Objective To analyze the causes of surgical complications after treatment of lumbar disc herniation (LDH and lumbar intervertebral foraminal stenosis by percutaneous transforaminal endoscopic discectomy (PTED.  Methods From December 2009 to December 2014, 286 patients with LDH (N = 201 and lumbar intervertebral foraminal stenosis (N = 85 were confirmed by X-ray, CT or MRI and treated by PTED in our hospital. Visual Analogue Scale (VAS was used to evaluate the degree of pain in each paitent before and after operation. The curative effect was evaluated by Macnab score. Surgical complications were recorded to find out the causes and methods to prevent them.  Results All cases were followed up for 3 months, and the VAS score decreased significantly compared with preoperation [1.00 (0.00, 1.05 vs 8.50 (7.75, 9.25; Z = 2.825, P = 0.050]. According to Macnab score, the rate of excellent and good functional recovery was 95.45% (273/286. Procedure-related complications included nerve injury in 8 cases (2.80%, hemorrhage at the operation site and hematoma formation around nerve root in 6 cases (2.10%, rupture of dural sac in one case (0.35%, muscle cramps in 3 cases (1.05%, surgical infection in one case (0.35%, postoperative recurrence in 4 cases (1.40%. All patients with complications were cured after symptomatic treatment. Conclusions The overall effect of percutaneous transforaminal endoscopic discectomy for treating lumbar disc herniation and lumbar intervertebral foraminal stenosis is satisfactory, which has a low incidence rate of postoperative complications. Some tips can effectively reduce the rate of surgical complications such as preoperative evaluation, precise performance, careful hemostasis, shortening the operation time and postoperatively symptomatic treatment, etc. DOI: 10.3969/j.issn.1672-6731.2016.04.007

    2012-01-01

    Conclusions: Preoperative recurrent IVU, together with high-grade reflux, seem to correlate to lower success rate of Deflux injection for primary VUR. Even after successful endoscopic treatment, long-term surveillance may be needed among these cases, mainly if voiding dysfunction is also recorded. Late recurring VUR must be actively excluded in case of new IVU episodes.

    Purpose: Evaluation of a percutaneous transhepatic treatment of symptomatic choledocholithiasis in bile ducts that cannot be reached with the endoscope. Methods: From January 1996 to August 2000 a transhepatic extraction of biliary calculus was performed in four patients. Endoscopic retrograde cholangiography (ERC) was not successful in any of the cases. Clinical symptoms were icterus in four cases, additional cholangitis or colics in two cases. First, a ballon dilation of the papilla was performed by a percutaneous transhepatic approach. For removal of bile duct stones, occlusion catheters and Dormia baskets were used. Technical success was defined as complete removal of bile duct stones. Clinical success was defined as normalization of cholestasis and inflammation parameters. In the follow-up an ultrasound examination was performed and blood samples were taken for control of cholestasis parameters. Results: In all four cases treatment was technically and clinically successful. For complete removal of biliary calculus a second intervention was necessary in two cases. In each case an internal to external drainage was left over a mean of 7 days (3 - 13 days). In the mean follow-up of 30.5 months (6 - 50 months) all patients had persistent relief of symptoms. No further interventions were necessary. No complications were present. Conclusion: Percutaneous transpapillary extraction of biliary calculus is an effective alternative to surgery in patients with bile ducts, that cannot be reached with the endoscope. (orig.)

  19. Exploring the efficacy of endoscopic ventriculostomy for hydrocephalus treatment via a multicompartmental poroelastic model of CSF transport: a computational perspective.

    Directory of Open Access Journals (Sweden)

    John C Vardakis

    Full Text Available This study proposes the implementation of a Multiple-Network Poroelastic Theory (MPET model coupled with finite-volume computational fluid dynamics for the purpose of studying, in detail, the effects of obstructing CSF transport within an anatomically accurate cerebral environment. The MPET representation allows the investigation of fluid transport between CSF, brain parenchyma and cerebral blood, in an integral and comprehensive manner. A key novelty in the model is the amalgamation of anatomically accurate choroid plexuses with their feeding arteries and a simple relationship relaxing the constraint of a unique permeability for the CSF compartment. This was done in order to account for the Aquaporin-4-mediated swelling characteristics. The aim of this varying permeability compartment was to bring to light a feedback mechanism that could counteract the effects of ventricular dilation and subsequent elevations of CSF pressure through the efflux of excess CSF into the blood system. This model is used to demonstrate the impact of aqueductal stenosis and fourth ventricle outlet obstruction (FVOO. The implications of treating such a clinical condition with the aid of endoscopic third (ETV and endoscopic fourth (EFV ventriculostomy are considered. We observed peak CSF velocities in the aqueduct of the order of 15.6 cm/s in the healthy case, 45.4 cm/s and 72.8 cm/s for the mild and severe cases respectively. The application of ETV reduced the aqueductal velocity to levels around 16-17 cm/s. Ventricular displacement, CSF pressure, wall shear stress (WSS and pressure difference between lateral and fourth ventricles (ΔP increased with applied stenosis, and subsequently dropped to nominal levels with the application of ETV. The greatest reversal of the effects of atresia come by opting for ETV rather than the more complicated procedure of EFV.

  20. Surgical treatment of choanal atresia with transnasal endoscopic approach with stentless single side-hinged flap technique: 5 year retrospective analysis

    Directory of Open Access Journals (Sweden)

    Carmelo Saraniti

    Full Text Available Abstract Introduction: Choanal atresia is a rare congenital malformation of the nasal cavity characterized by the complete obliteration of the posterior choanae. In 67% of cases choanal atresia is unilateral, affecting mainly (71% the right nasal cavity. In contrast to the unilateral form, bilateral choanal atresia is a life-threatening condition often associated with respiratory distress with feeding and intermittent cyanosis exacerbated by crying. Surgical treatment remains the only therapeutic option. Objective: To report our experience in the use of a transnasal endoscopic approach with stentless single side-hinged flap technique for the surgical management of choanal atresia. Methods: A 5 year retrospective analysis of surgical outcomes of 18 patients treated for choanal atresia with a transnasal technique employing a single side-hinged flap without stent placement. All subjects were assessed preoperatively with a nasal endoscopy and a Maxillofacial computed tomography scan. Results: Ten males and eight females with a mean age at the time of surgery of 20.05 ± 11.32 years, underwent surgery for choanal atresia. Fifteen subjects (83.33% had a bony while 3 (26.77% a mixed bony-membranous atretic plate. Two and sixteen cases suffered from bilateral and unilateral choanal atresia respectively. No intra- and/or early postoperative complications were observed. Between 2 and 3 months after surgery two cases (11.11% of partial restenosis were found. Only one of these presented a relapse of the nasal obstruction and was subsequently successfully repaired with a second endoscopic procedure. Conclusion: The surgical technique described follows the basic requirements of corrective surgery and allows good visualization, evaluation and treatment of the atretic plate and the posterior third of the septum, in order to create the new choanal opening. We believe that the use of a stent is not necessary, as recommended in case of other surgical techniques

    Open surgical excision of the os trigonum has been the traditional treatment for posterior ankle impingement syndrome (PAIS). However, the endoscopic excision has recently become quite popular. Purpose/Hypothesis: The purpose of our study was to compare the results of endoscopic versus open excision of a symptomatic os trigonum for the treatment of PAIS in an athletic population. It was hypothesized that the endoscopic technique would be superior to the open technique regarding functional outcomes, pain, and time to return to training and the previous sports level. Randomized controlled trial; Level of evidence, 2. From 2008 to 2011, 52 athletes underwent a symptomatic os trigonum excision; 26 athletes had an open procedure (group A) and 26 had an endoscopic procedure (group B). The American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score and the Visual Analog Score-Foot and Ankle (VAS-FA) were obtained, and the time to return to training and to previous sports level was recorded. Patients in group B appeared to have significant improvement of AOFAS hindfoot score compared with those in group A ( P os trigonum is a safe and effective treatment option for athletes who require early return to their previous sports level.

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

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

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

    Two-stage treatment involving stone removal after drainage is recommended for mild to moderate acute cholangitis associated with choledocholithiasis. However, single-stage treatment has some advantages. We aimed to assess the efficacy and safety of single-stage endoscopic treatment for mild to moderate acute cholangitis associated with choledocholithiasis. A multicenter, non-randomized, open-label, exploratory clinical trial was performed in 12 institutions. A total of 50 patients with a naïve papilla and a body temperature ≥37 °C who were diagnosed with mild to moderate cholangitis associated with choledocholithiasis were enrolled between August 2012 and February 2014. Of the 50 patients, 15 had mild cholangitis and 35 had moderate cholangitis. The median number of common bile duct stones was 2 (range, 1-8), and the median diameter of the common bile duct stones was 7.5 mm (range, 1-18). The cure rate of acute cholangitis within 4 days after single-stage treatment was 90% (45/50) based on a body temperature choledocholithiasis (clinical trial registration number: UMIN000008494). © 2015 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

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

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

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

    Bleeding from gastric varices is generally more severe than bleeding from esophageal varices, although it occurs less frequently. Recently, new endoscopic treatment options and interventional radiological procedures have broadened the therapeutic armamentarium for gastric varices. This review provides an overview of the classification and pathophysiology of gastric varices, an introduction to current endoscopic and interventional radiological management options for gastric varices, and details of a practical approach to endoscopic variceal obturation using N-butyl-2-cyanoacrylate.

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

    Achalasia is a rare primary motility disorder of esophagus; treatments include endoscopic balloon dilatation (EBD) and laparoscopic Heller's cardiomyotomy (LC). This study compared EBD versus LC for treatment of achalasia with focus on quality of life (QoL) and prevalence of post-treatment gastroesophageal reflux disease. This was a retrospective cohort study of all patients diagnosed with achalasia older than 16 treated with either EBD or LC from January 1998 to April 2008. Patients' demographic data, comorbidities, postintervention GERD symptoms, QoL, recurrence of dysphagia, reintervention rate, hospital stay, and time to resumption of diet were collected. Sixty-eight patients were recruited into the study (EBD n= 50; LC n= 18). A significant improvement in QoL was found in patients undergoing LC (0.917 vs. 0.807, P= 0.006). A higher proportion of patients treated with EBD developed post-treatment gastroesophageal reflux symptoms (60.5% vs. 43.8%) when compared with LC, although statistically insignificant (P= 0.34). Patients treated with balloon dilatation had a greater percentage of recurrence of dysphagia (55.1% vs. 26.7%; P= 0.235) and need of reintervention (42.1% vs. 9.1%; P= 0.045). However, these patients had a shorter median hospital stay (1d [range 0-4]) and earlier resumption of diet (0d [range 0-3]). Although EBD is associated with a quicker perioperative recovery, LC accomplished a better QoL, lower incidence of recurrence of dysphagia, and need of reintervention after treatment for achalasia. © 2012 Copyright the Authors.

The Eckardt score was 7–12 (type III. Seventeen (85% POEM procedures were performed in the Endoscopy Department, according to a previous study. During POEM, CO2 insufflation was mandatory, while the Triangle Tip knife was the only knife used in all procedures. Eckardt score, esophagogram and manometry before and after performing POEM were used for evaluation of our results. The follow-up period was 6 months to 3 years.Results: Selective circular myotomy, 10–13 cm in length, was successfully completed in all patients without severe acute or late complications. Three patients (15% showed moderate pneumomediastinum and pneumoperitoneum, which was successfully managed by abdominal needle drainage during the procedure. One patient showed mild pleural collection, and in one patient the clip–endoloop technique was used to successfully close the mucosal entry after the completion of POEM. The outcome was uneventful without any further clinical consequences. No other short- or long-term serious complications were reported. Patients were discharged after 1–3 days of hospitalization.

DATA SOURCE: Relevant publications cited at PubMed database in the last 10 years were analyzed and compared with the experience developed at the Gastrointestinal Endoscopy Division of the Department of Gastroenterology of the University of São Paulo School of Medicine. Mucosectomy and advanced tumor tunnelization were the most important developments in that area. DATA SYNTHESIS: Endoscopic mucosal resection of early epidermoid cancer of the esophagus is indicated when the lesion is confined to the epithelium (m1 or to the lamina propria (m2. The described 5-year survival rate after endoscopic mucosal resection of intramucosal epidermoid tumor of the esophagus approaches 95%. Based on the available evidence, it seems reasonable to indicate endoscopic mucosal resection as a first-choice treatment for patients with intramucosal epidermoid esophageal carcinoma. There are a variety of endoscopic palliative methods for dysphagia relief in advanced esophageal cancer. CONCLUSIONS: The choice will vary according to the anatomical features and location of the tumor, patient preferences, local and expertise availability. The technical success rate for placement of metal stents across the malignant stenosis is close to 100%. The rate of long-term palliation of dysphagia approaches 80% which makes expandable metal stents the treatment of choice for palliation of obstructive symptoms caused by advanced squamous cell cancer of the esophagus.

    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

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

    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.

  4. Design and performance of optical endoscopes for the early detection of cancer

    Science.gov (United States)

    Keenan, Maureen Molly

    Cancer is a multistage, heterogeneous disease that develops through a series of genetic mutations. Early stage cancer is most responsive to treatment but can be the hardest to detect due to its small size, lack of definitive symptoms and potential location deep in the body. Whole body imaging methods, MRI/CT/PET, lack the necessary resolution to detect cellular level abnormalities. Optical methods, which have sufficient resolution, can be miniaturized into endoscopes, which are necessary to overcome limited penetration of light into tissue. By combining optical coherence tomography (OCT) and fluorescence imaging methods it is possible to create endoscopes sensitive to molecular and structural changes. I applied a dual-modality 2mm diameter rigid endoscope to the study of the natural history of colon cancer in a mouse model, and later applied this knowledge to the design and characterization of a 0.8 mm dual-modality flexible probe for use in human fallopian tubes. By using this endoscope, which is introduced through the natural orifice and is compatible with existing hysteroscopes, high-risk women could be screened in a procedure at a similar level of invasiveness as a colonoscopy. Therefore, the endoscope fills this gap in clinical care for women at high-risk for ovarian cancer.

    2015-01-01

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

    We compare the outcomes and postoperative MRI changes of endoscopic endonasal (EEA) and bifrontal craniotomy (BFC) approaches for olfactory groove meningiomas (OGM). All patients who underwent either BFC or EEA for OGM were eligible. Matched pairs were created by matching tumor volumes of an EEA patient with a BFC patient, and matching the timing of the postoperative scans. The tumor dimensions, peritumoral edema, resectability issues, and frontal lobe changes were recorded based on preoperative and postoperative MRI. Postoperative fluid-attenuated inversion recovery (FLAIR) hyperintensity and residual cystic cavity (porencephalic cave) volume were compared using univariable and multivariable analyses. From a total of 70 patients (46 EEA, 24 BFC), 10 matched pairs (20 patients) were created. Three patients (30%) in the EEA group and two (20%) in the BFC had postoperative cerebrospinal fluid leaks (p=0.61). Gross total resections were achieved in seven (70%) of the EEA group and nine (90%) of the BFC group (p=0.26), and one patient from each group developed a recurrence. On postoperative MRI, there was no significant difference in FLAIR signal volumes between EEA and BFC approaches (6.9 versus 13.3 cm(3); p=0.17) or in porencephalic cave volumes (1.7 versus 5.0 cm(3); p=0.11) in univariable analysis. However, in a multivariable analysis, EEA was associated with less postoperative FLAIR change (p=0.02) after adjusting for the volume of preoperative edema. This study provides preliminary evidence that EEA is associated with quantifiable improvements in postoperative frontal lobe imaging. Copyright © 2015 Elsevier Ltd. All rights reserved.

    New endoscopic techniques for hemostasis in nonvariceal bleeding were introduced and known methods further improved. Hemospray and Endoclot are two new compounds for topical treatment of bleeding. Initial studies in this area have shown a good hemostatic effect, especially in active large scale oozing bleeding, e.g., tumor bleedings. For further evaluation larger prospective studies comparing the substanced with other methods of endoscopic hemostasis are needed. For localized active arterial bleeding primary injection therapy in the area of ​​bleeding as well as in the four adjacent quadrants offers a good method to reduce bleeding activity. The injection is technically easy to learn and practicable. After bleeding activity is reduced the bleeding source can be localized more clearly for clip application. Today many different through-the-scope (TTS) clips are available. The ability to close and reopen a clip can aid towards good positioning at the bleeding site. Even more important is the rotatability of a clip before application. Often multiple TTS clips are required for secure closure of a bleeding vessel. One model has the ability to use three clips in series without changing the applicator. Severe arterial bleeding from vessels larger than 2 mm is often unmanageable with these conventional methods. Here is the over-the-scope-clip system another newly available method. It is similar to the ligation of esophageal varices and involves aspiration of tissue into a transparent cap before closure of the clip. Thus a greater vascular occlusion pressure can be achieved and larger vessels can be treated endoscopically. Patients with severe arterial bleeding from the upper gastrointestinal tract have a very high rate of recurrence after initial endoscopic treatment. These patients should always be managed in an interdisciplinary team of interventional radiologist and surgeons.

    Full Text Available Background: in recent years new endoscopic strategies and techniques for the treatment of obesity have emerged and developed. Aim of the study: in this article we will review and analyze the current state of the following techniques and the basic differential characteristics between each of them: balloons and prosthesis, injection of substances, systems of sutures, malabsorptives techniques and others currently in research. Methods: we will evaluate the endoscopic technique and their main indications, results, tolerances, complications and adverse effects observed, reporting our personal experience and in relation with an extensive literature review. Results: comparatively with the most widespread technique of the Bioenterics balloon, the Spatz balloon can provide greater weight loss but with worse tolerance and more complications and the Heliosphere Bag gets a similar weight loss but with greater technical difficulty. Other balloons and prosthesis (Ullorex, Semistationary, Silimed, Endogast still require technical improvements and higher studies. The injection of botulinum toxin, although secure, seems to offer a smaller and more transient efficacy. Suture systems (TOGa, Endoluminal vertical gastroplasty and POSE appear to be effective but are technically more laborious. Malabsorptives procedures (Endobarrier, ValenTX are somewhat laborious but effective, particularly indicated in obese patients with type 2 diabetes mellitus. Conclusions: the development of new endoscopic techniques and improvement in existing designs, suggest an increasingly important role of the endoscopist in the treatment of obesity. We consider it important to individually select and use the endoscopic technique, depending on the desirable outcomes (efficacy, tolerance, safety, adverse effects and risks and the experience of each hospital. We believe that these techniques should be applied by specifically trained endoscopists in specialized hospitals.Antecedentes: en los

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

    The aim of the present study was to compare elective transjugular intrahepatic portosystemic shunt (TIPS) and laparoscopic splenectomy (LS) plus preoperative endoscopic varices ligation (EVL) in their efficacy in preventing recurrent bleeding and improving the long-term liver function in patients with liver cirrhosis and portal hypertension. Between January 2009 and March 2012, we enrolled 83 patients (55 with TIPS, defined as the TIPS group, and 28 with LS plus preoperative EVL, defined as the LS group) with portal hypertension and a history of gastroesophageal variceal bleeding resulting from liver cirrhosis. The clinical characteristics, perioperative outcomes, and follow-up were recorded. No significant differences were observed between the two treatment groups with respect to the patients' characteristics and preoperative variables. Within 30 days after surgery, one patient in the TIPS group died of multiple organ dysfunction syndrome, whereas no patient in the LS group died. Complications occurred in 14 patients in the TIPS group, which included rebleeding, encephalopathy, ascites, bleeding from a pseudoaneurysm of the thoracoabdominal aorta, and pulmonary infection, compared with 5 patients in the LS group, which included pulmonary effusion, pancreatic leakage, and portal vein thrombosis. During a mean follow-up of 13.6 months in the TIPS group and 12.3 months in the LS group, the actuarial survival was 85.5 % in the TIPS group versus 100 % in the LS group. The long-term complications included rebleeding and encephalopathy in the TIPS group. LS plus EVL was superior to TIPS in the prevention of gastroesophageal variceal rebleeding in cirrhotic patients. This treatment was associated with a low rate of portosystemic encephalopathy and improvements in the long-term liver function.

    Per-oral endoscopic myotomy (POEM) has received wide acceptance as a highly effective and safe treatment for esophageal achalasia. Short-term and small-scale studies are ample, but long-term large-scale studies are few. The aim of the study was to systematically analyze our long-term results of POEM, with particular emphasis on POEM failures and associated risk factors. In this single-center study, consecutive patients treated with POEM between August 2010 and December 2012 were included. The Kaplan-Meier survival function was used to estimate clinical success rate at each year. The Cox proportional hazards model was used to analyze risk factors related to recurrence. A total of 564 patients were included. Major perioperative adverse events occurred in 36 patients (6.4%). After a median follow-up of 49 months (range, 3-68), the Eckardt score and lower esophageal sphincter (LES) pressure were significantly decreased (median Eckardt score, 8 to 2 [P < .05]; median LES pressure, 29.7 mm Hg to 11.9 mm Hg [P < .05]). Fifteen failures occurred within 3 months, 23 between 3 months and 3 years, and 10 after 3 years. The estimated clinical success rates at 1, 2, 3, 4, and 5 years were 94.2%, 92.2%, 91.1%, 88.6%, and 87.1%, respectively. Multivariate Cox regression revealed long disease duration (≥10 years) and history of prior interventions to be risk factors for recurrence. Clinical reflux occurred in 37.3% of patients (155/ 416). POEM is a highly safe and effective treatment for esophageal achalasia with favorable long-term outcomes. Copyright © 2017 American Society for Gastrointestinal Endoscopy. Published by Elsevier Inc.

    Purpose The aim of this study was to compare cure rates and complications of polydimethylsiloxane (Macroplastique®) and dextranomer/hyaluronic acid copolymer (Deflux®) in the treatment of vesicoureteral reflux (VUR). Materials and Methods From April 2001 to March 2008, 29 boys and 42 girls (total of 115 ureters) with a mean age of 6 years who had undergone endoscopic subureteral transurethral injection for VUR were enrolled. A single subureteral injection of Macroplastique was performed in 31 ureters in 23 children (group I; grade II: 4; grade III: 12; grade IV: 9; grade V: 6), and a single subureteral injection of Deflux was performed in 84 ureters in 48 children (group II; grade II: 24; grade III: 14; grade IV: 25; grade V: 21). Renal ultrasound was done 1 day after injection, and voiding cystourethrography (VCUG) was done at 3 months. Successful reflux correction was defined as absent or grade I reflux on follow-up VCUG. Results No significant difference in success rates was observed between group I and group II [80.6% (25/31) vs. 78.6% (66/84), respectively, p>0.05]. The following postoperative complications developed: ureteral obstruction in 2 ureters of group I and 3 ureters of group II, asymptomatic urinary tract infection in 3 patients of group I and 2 patients of group II, and bladder calcification by erosion or mucosal necrosis in 2 patients of group I. Conclusions Despite differences in material properties, both Macroplastique and Deflux were safe for the treatment of children with VUR. Because of the risk of bladder mucosal necrosis and substantial decreases in volume after implantation, long-term follow-up is required. PMID:20414426

    Full Text Available Colonoscopic screening in developed countries allows detection and resection of a great number of early colorectal cancers. There is a strong controversy to decide when endoscopic treatment is enough or when surgical resection is necessary. To this contributes the diverse names to define the lesions, the wide number of classifications and the different criteria of each author. We perform an extense literature review, aiming to clarify concepts and unify criteria that can be used as a guide for the treatment of early colorectal cancer. We conclude that in early colorectal cancer arising in pedunculated polyps (0-Ip, mucosal endoscopic resection would be indicated as only treatment in Haggitt levels 1, 2 and 3, tumors smaller than 2 cm, well- or moderately differentiated, without vascular or lymphatic affection, with submucosal infiltration lower than 1 µm from the muscularis mucosae and maximal submucosal width lower than 4 µm, and undergoing en bloc resection. In sessile polyps (0-Is or non-polypoideal elevated (0-IIa or plain (0-IIb lesions, recommendations will be similar, without applicability of Haggitt levels.El screening mediante colonoscopia que se realiza en países occidentales ha permitido la detección y resección de un número elevado de tumores colorrectales en estadio temprano.

    Full Text Available Introduction. Lumbar disc herniation is a frequent pathology and surgical target. Endoscopic discectomy becomes more popular due to minimally invasive surgical technique. There is a deficit of scientific papers dedicated to analysis of potential for endoscopic discectomy depending on the specifics of spinal anatomy and degenerative changes.The purpose of the study was to evaluate the efficacy of transforaminal endoscopic discectomy (TED in comparison with microdiscectomy (MD and to specify factors determining complications and failures.Materials and methods. The authors performed randomized controlled study where main group of patients included data on prospective examination of 101 patients after TED procedure for lumbar intervertebral disc herniation. Age of patients ranged from 19 to 81 years with average of 41,4±12,6 years. Control group included data of retrospective examination of 153 patients that were operated by the same surgeon in the period from 201 till 2104 with microdiscectomy procedure. Age of patients ranged from 18 to 77 years with average of 47,8±11,3 years. Inclusion criteria were as follows: surgical procedure at the same level of the primary intervertebral herniation. Exclusion criteria were: degenerative spinal canal stenosis, spondylolisthesis, spine deformity.Results. Clinical outcomes after TED demonstrated no difference from MD procedure. No factors of significant influence on outcomes after surgical procedure were observed. The main group was characterized by more cases of revisions and conversions of endoscopic into open procedures (13,9% which was related to mistakes in transforaminal approach due to features of intervertebral joints and foramina anatomy resulting in impossibility to achieve adequate spinal canal decompression.Conclusion. Transforaminal endoscopic discectomy is an effective and safe method of lumbar intervertebral herniation treatment. Complications and failures during learning curve of endoscopic

    Acute gastrointestinal bleeding is among the most urgent situations in daily gastroenterological practise. Endoscopy plays a key role in the diagnosis and treatment of such cases. Endoscopic haemostasis is probably the most important technical challenge that must be mastered by gastroenterologists. It is essential for both the management of acute gastrointestinal haemorrhage and the prevention of bleeding during high-risk endoscopic procedures. During the last decade, endoscopic haemostasis techniques and tools have grown in parallel with the number of devices available for endotherapy. Haemostatic powders, over-the-scope clips, haemostatic forceps, and other emerging technologies have changed daily practise and complement the standard available armamentarium (injectable, thermal, and mechanical therapy). Although there is a lack of strong evidence-based information on these procedures because of the difficulty in designing statistically powerful trials on this topic, physicians must be aware of all available devices to be able to choose the best haemostatic tool for the most effective procedure. We herein present an overview of procedures and clinical scenarios to optimise the management of gastrointestinal bleeding in daily practise.

    A 26-year-old woman with a congenital port-wine stain on the forehead was treated three times at 2-month intervals with an argon laser. Six months after the last treatment, moderate blanching and mild scaling confined to the treated area was observed. A biopsy specimen of the treated area revealed a significant decrease in ectatic vessels. However, epidermal changes similar to those of actinic keratosis with disorganized cell layers and marked cytologic abnormalities were seen. Analysis of peripheral blood lymphocytes for a defect in DNA repair was negative. Multiple, argon laser-induced photothermal effects may be responsible for the changes observed in our case and may lead to premalignant epidermal transformation.

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

    Introduction: Diagnosis and treatment of vaginal and cervical cytological cell changes are described in European and national guidelines. The aim of this data collection was to evaluate the remission rates of PAP III and PAP III D cytological findings in patients over a period of 3–4 months. Method: The current state of affairs in managing suspicious and cytological findings (PAP III, and III D) in gynecological practice was assessed in the context of a data collection survey. An evaluation over a period of 24 months was conducted on preventative measures, the occurrence and changes to normal/suspect/pathological findings and therapy management (for suspicious or pathological findings). Results: 307 female patients were included in the analysis. At the time of the survey 186 patients (60.6 %) had PAP III and 119 (38.8 %) had PAP III D findings. The spontaneous remission rate of untreated PAP III patients was 6 % and that of untreated PAP III D patients was 11 %. The remission rates of patients treated with a vaginal gel were 77 % for PAP III and 71 % for PAP III D. Conclusion: A new treatment option was used in gynecological practice on patients with PAP III and PAP III D findings between confirmation and the next follow-up with excellent success.

    Prior studies show promising results of the gastric peroral endoscopic pyloromyotomy (G-POEM) procedure for treatment of refractory gastroparesis. One major technical challenge involved in this procedure is identifying the pyloric muscular ring (PMR). The aim of this study is to establish a reliable method for identification of the PMR during G-POEM. Fluoroscopy-guided G-POEM was performed by placing an endoclip at the 9 to 11'o clock position at the pylorus for identification of PMR. Conventional G-POEM was performed by observation of blue colored mucosa at the pylorus area as an indirect marker for PMR. The degree of the PMR identification was graded into well identified, identified, and not identified based on the appearance of the PMR. Procedure times were accurately documented. Gastroparesis cardinal symptoms index and gastric emptying scintigraphy were evaluated before and after the procedure. Fourteen patients were studied, seven underwent fluoroscopy-guided G-POEM, and seven patients underwent conventional G-POEM. All procedures achieved technical success and no adverse events occurred. In the seven patients who underwent fluoroscopy-guided G-POEM, the PMR was well identified in four patients and identified in three patients. In the seven patients who underwent conventional G-POEM, the PMR was identified in four patients and not identified in three patients. The average time to complete the fluoroscopy-guided G-POEM was significantly shorter than that of the conventional G-POEM. Fluoroscopy-guided G-POEM by placement of an endoclip at the pylorus was a reliable and safe method to direct the orientation of the submucosal tunnel, to facilitate the location of the PMR, and to shorten the procedure time.

    Dysphagia is common after stroke. Neuromuscular electrical stimulation (NMES) and fiberoptic endoscopic evaluation of swallowing (FEES) for the treatment of dysphagia have gained in popularity, but the combined application of these promising modalities has rarely been studied. We aimed to evaluate whether combined NMES, FEES, and traditional swallowing rehabilitation can improve swallowing functions in stroke patients with moderate to severe dysphagia. Thirty-two patients with moderate to severe dysphagia poststroke (≥3 weeks) were recruited. Patients received 12 sessions of NMES for 1 h/day, 5 days/week within a period of 2-3 weeks. FEES was done before and after NMES for evaluation and to guide dysphagic therapy. All patients subsequently received 12 sessions of traditional swallowing rehabilitation (50 min/day, 3 days/week) for 4 weeks. Primary outcome measure was the Functional Oral Intake Scale (FOIS). Secondary outcome measures included clinical degree of dysphagia, the patient's self-perception of swallowing ability, and the patient's global satisfaction with therapy. Patients were assessed at baseline, after NMES, at 6-month follow-up, and at 2-year follow-up. Twenty-nine patients completed the study. FOIS, degree of dysphagia, and patient's self-perception of swallowing improved significantly after NMES, at the 6-month follow-up, and at the 2-year follow-up (p rehabilitation showed promise for improving swallowing functions in stroke patients with moderate-to-severe dysphagia. The benefits were maintained for up to 2 years. The results are promising enough to justify further studies.

    Subureteral injection of dextranomer/hyaluronic acid copolymer is a minimally invasive method to treat vesicoureteral reflux. We report short and long-term success in treating secondary vesicoureteral reflux in patients with neurogenic bladder dysfunction or severe voiding dysfunction. We performed a retrospective chart review of all subureteral injection procedures done to identify patients with neurogenic bladder or severe voiding dysfunction. Short (less than 12 months) and long-term vesicoureteral reflux results for patients and ureters were recorded. Preoperative urodynamics and radiographic findings were reviewed. Preoperative factors were evaluated to identify patients with greater chances of success. A total of 12 patients (17 ureters) were identified (10 with neurogenic bladder and 2 with Hinman syndrome). Short-term success (no vesicoureteral reflux) was achieved in 50% of patients and 58% of ureters. At a median followup of 4.5 years (range 1 to 9) success decreased to 35% of ureters. Overall, long-term success was found in 25% of patients who were free of vesicoureteral reflux and required no additional surgery. Of the patients 41% required additional urological surgery for vesicoureteral reflux or related conditions. With long-term followup many patients who had initial improvement in vesicoureteral reflux ultimately experienced treatment failure and recurrence of reflux. At a median of 4.5 years 25% of patients with neurogenic bladder and vesicoureteral reflux were successfully treated with endoscopic injection of dextranomer/hyaluronic acid copolymer.

    Percutaneous transforaminal endoscopic discectomy (PTED) is a minimally invasive surgical technique used principally for the treatment of lumbar disc herniation (LDH). LDH is a frequent spinal ailment in obese individuals. The aim of this prospectively designed study was to assess for the first time in the literature the impact of PTED in postoperative parameters of health-related quality of life (HRQoL) in obese patients with LDH within a 2-year follow-up period, to further evaluate the effectiveness of PTED. Patients with surgically treatable LDH were divided into 2 groups. Group A constituted 20 obese patients, and group B was composed of 10 patients with normal body mass index (BMI). A visual analog scale was used for pain evaluation, and the Short Form SF-36 Medical Survey Questionnaire contributed to HRQoL assessment. Follow-up was conducted preoperatively and at 6 weeks and 3, 6, 12, and 24 months postoperatively. Two of the 20 patients (10%) presented with severe postoperative pain, necessitating conventional microdiscectomy. All studied parameters exhibited maximal improvement at 6 months in group A and at 6 weeks in group B, with subsequent stabilization. Obese patients scored lower in all parameters compared with their healthy counterparts with normal BMI, acquiring a less favorable clinical benefit. PTED appears to be a generally safe and effective method for treating obese patients with LDH. However, major technical challenges that lead to a higher frequency of complications, as well as the lesser acquired clinical benefit, in obese patients may contribute to the further consideration for PTED in specific obese patients, especially on the grounds of low surgical experience.

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

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

    The pathogenesis of painful heel syndrome is multifactorial including plantar fasciitis, increased intra-osseous pressure of the os calcis, calcaneal periostitis and presence of calcaneal spur. The currently used endoscopic treatment of painful heel syndromes involves endoscopic plantar fascia release alone without addressing other pathological changes. To evaluate the clinical outcome of endoscopic plantar fascia release, calcaneal drilling and calcaneal spur removal. The study was conducted on 22 cases/24 feet with idiopathic painful heel syndrome resistant to conservative treatment. All cases were treated by plantar fasciotomy; calcaneal drilling and calcaneal spur removal using a modified cannula trocar system. Evaluation of pain was done using VAS and functional evaluation was done using the Modified Mayo Scoring System for Plantar Fasciotomy. Also patient's satisfaction was evaluated by direct questionnaire. There was statistically significant improvement in the mean VAS from 82.81 (±7.8 std) preoperative to 6.63 (±2.75 std) and the Mayo score form 7.05 (±3.67 std) preoperative to 87.5 (±4.81 std) at 2 years follow up (Pcalcaneal drilling and calcaneal spur removal has high success rate and patient's satisfaction rate when compared to published reports on isolated endoscopic plantar release.

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

    2017-01-01

    Peroral endoscopic myotomy (POEM) has been considered as a minimal-invasive, innovative technique for long-term treatment of all types of esophageal achalasia and other esophageal motility disorders. We report on 20 consecutive Greek patients with manometrically proved esophageal achalasia (14 patients with type I, 4 with type II, 2 with type III, and 4 with sigmoid esophagus), with an age range of 32-92 years, mean age 59 years, 12 males, successfully treated by POEM from 2013 to 2015. The Eckardt score was 7-12 (type III). Seventeen (85%) POEM procedures were performed in the Endoscopy Department, according to a previous study. During POEM, CO 2 insufflation was mandatory, while the Triangle Tip knife was the only knife used in all procedures. Eckardt score, esophagogram and manometry before and after performing POEM were used for evaluation of our results. The follow-up period was 6 months to 3 years. Selective circular myotomy, 10-13 cm in length, was successfully completed in all patients without severe acute or late complications. Three patients (15%) showed moderate pneumomediastinum and pneumoperitoneum, which was successfully managed by abdominal needle drainage during the procedure. One patient showed mild pleural collection, and in one patient the clip-endoloop technique was used to successfully close the mucosal entry after the completion of POEM. The outcome was uneventful without any further clinical consequences. No other short- or long-term serious complications were reported. Patients were discharged after 1-3 days of hospitalization. Six months to 3 years after the POEM procedure, all patients were alive; the majority (90%) had complete clinical improvement, while two patients with sigmoid-type achalasia showed moderate-to-significant clinical improvement. Erosive esophagitis was reported in 15%. Our results are in accordance with international data, and proved the safety and efficacy of the POEM technique for radical long-term treatment of all

    The herniated nucleus pulposus (HNP) is a very common disorder. In those patient, who do not respond, more direct therapeutic measures, may be necessary. The chymopapain cheomonuclelysis, after two decades of development, has provided a variable alternative to surgical diskectomy for treatment of HNP. The changes of CT scan follow-up 1 month and 3 month that occur in the disks of those patient who respond to chymopapain chemonucleolysis must be defined and evaluation of temporal radiographic changes may also help clarity mechanism by which chemonucleolysis relieves sciatic pain caused by HNP. The results were as follows: 1. Our data indicates that chymopapain chemonucleolysis was effective in 70% and 90% of patients at both 1 M. and 3 M. follow-up. (average 80%) 2. At 1 M. follow-up, a successful response was noted in 70% of patients, with all significant intervertebral disc space narrowing (average 2.7 mm) and 30% of them showing an observable diminution in the herniated disc fragment (average 0.8 mm). At 3 M. follow-up, a successful response was noted in 90% of patients, with 70% of them showing significant narrowing (average 1.2 mm) and observable diminution in the herniated disc fragment (average 1.5 mm). The refor, with 3 M. follow-up, the CT changes did become more pronounced with greater number of patients exhibiting a diminution of the disk herniation and interspace narrowing, and associated with more progressive improvement of clinical outcome. 3. New vaccum phenomenon and extradiskal effects of chymopapain appear to be absent. 4. At 1 M. follow-up, Housefield Unit (HU) of disk is generally increased (average 8.8 HU) and at 3 M. follow-up, it is decreased (average 6 HU)

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

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

    Per-oral endoscopic myotomy (POEM) was developed less than a decade ago for the treatment of achalasia. Its minimally invasive approach and the favorable short-term outcome have led to rapid adoption of the technique throughout the world. As with any new technique, there will be adverse events, and it is important that effective treatments for these adverse events be discussed. We present a case of successful endoscopic management of an intramural sinus leak after a POEM procedure using tandem fully covered esophageal stents.

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

    2014-01-01

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

    Full Text Available Objective is to analyze the surgical strategy, safety, and clinical results of percutaneous full-endoscopic discectomy through interlaminar or extraforaminal puncture technique for LDH. Preoperative CT and MRI were analyzed, which were based on the main location of the herniated disc and its relationship with compressed nerve root. Sixty-two patients satisfied the inclusion criteria during the period from August 2012 to March 2014. We use percutaneous full-endoscopic discectomy through different puncture technique to remove the protrusive NP for LDH. Sixty patients completed the full-endoscopic operation successfully. Their removed disc tissue volume ranged from 1.5 mL to 3.8 mL each time. Postoperative ODI and VAS of low back and sciatica pain were significantly decreased in each time point compared to preoperative ones. No nerve root injury, infection, and other complications occurred. The other two patients were shifted to open surgery. No secondary surgery was required and 91.6% of excellent-to-good ratio was achieved on the basis of Macnab criteria at postoperative 12 months. Acquired benefits are fewer complications, rapid recovery, complete NP removal, effective nerve root decompression, and satisfactory cosmetic effect as well. This is a safe, effective, and rational minimally invasive spine-surgical technology with excellent clinical outcome.

    2018-04-17

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

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

    Full Text Available Gastroesophageal reflux disease results primarily from the loss of an effective antireflux barrier, which forms a mechanical barrier against the retrograde movement of gastric contents. Multiple devices have been developed for the endoscopic treatment of GERD, using approaches such as sewing, transmural fasteners, endoscopic staplers, and thermal treatment. Devices that are currently commercially available for the endoscopic treatment of GERD in the US include: EndoCinch; EsophyX; Stretta. This article will highlight the endoscopic therapy of gastroesophageal reflux disease with focus on Stretta and EsophyX.

    Colonoscopic location of a tumor can influence both the surgical procedure choice and overall treatment strategy. To determine the accuracy of colonoscopy in determining the location of colon cancer compared to surgical localization and to elucidate factors that predict discordant colon cancer localization. We conducted a retrospective cross-sectional study of colon cancers diagnosed on colonoscopy at two academic tertiary-care hospitals and two affiliated community hospitals from 2012 to 2014. Colon cancer location was obtained from the endoscopic and surgical pathology reports and characterized by colon segment. We collected data on patient demographics, tumor characteristics, endoscopic procedure characteristics, surgery planned, and surgery performed. Univariate analyses using Chi-squared test and multivariate analysis using forward stepwise logistic regression were performed to determine factors that predict discordant colon cancer localization. There were 110 colon cancer cases identified during the study period. Inaccurate endoscopic colon cancer localization was found in 29% (32/110) of cases. These included 14 cases (12.7%) that were discordant by more than one colonic segment and three cases where the presurgical planned procedure was significantly changed at the time of surgery. On univariate analyses, right-sided colon lesions were associated with increased inaccuracy (43.8 vs 24.4%, p = 0.04). On multivariate analysis, right-sided colon lesions remained independently associated with inaccuracy (OR 1.74, 95% CI 1.03-2.93, p = 0.04). Colon cancer location as determined by colonoscopy is often inaccurate, which can result in intraoperative changes to surgical management, particularly in the right colon.

    Subureteral endoscopic injection of a bulking agent is an attractive alternative to open surgery or antibiotic prophylaxis for vesico ureteral reflux (VUR). Little information is available about long-term risk of recurrence after an initially successful treatment. Aim of this paper was to review short- and long-term success rate of endoscopic treatment in a single Center series after risk stratification of individual patients. The records of 126 patients who underwent Deflux injection for primary VUR were examined. Indications to treatment were an unvaried high grade VUR (IV-V) at 1 year from diagnosis and/or and recurrent urinary tract infection (UTI) on antibiotic prophylaxis even in the presence of mild grade VUR (III grade). Gender, age and mode of diagnosis, infections (UTI), voiding dysfunctions, VUR grade and side, renal function, number of treatments were correlated to outcome. Long-term evaluation was planned at a minimum of 1 year from the last negative post-injection cystogram (MCUG). A new MCUG and DMSA scan were also offered to those complaining new UTI episodes. Late recurrences were correlated to history and grade of reflux. Data were analyzed with Graph Pad Instat software; the Chi-square test was used for univariate comparisons, the Fisher's exact test for categorical variables.and multiple regression tests for factors influencing outcome. M/F ratio was 62 to 64; median age at diagnosis was 28 months. VUR affected 198 renal units. Preinjection VUR grade was I in 1, II in 27, III in 107, IV in 59, and V in 4 units. Reduced DMSA uptake was evidenced in 51 units and scarring in 24. Median age at treatment was 34.5 months, for persistent high grade VUR (IV-V) in 55 patients and recurrent IVU in 92. Two hundred sixty seven injections were performed on 198 ureters. Complete resolution was documented by MCUG at 3-5 months in 68%, low grading IVU, together with high-grade reflux, seem to correlate to lower success rate of Deflux injection for primary VUR

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

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

    Mucosal incision technique by diode laser ablation was studied to ensure the operation of endoscopic mucosal resection (EMR), which is gold standard method for early gastric cancer with little/no risk of lymphnode metastasis. Our method was designed to facilitate grasping a large lesion by hitching the snaring wire on the incised mucosal groove around the lesion. We employed local submucosal injection of indocyanine green (ICG) solution. ICG solution was used to prevent direct laser light penetration to the muscularis propriae owing to strong absorption of 805nm light (absorption coefficent at 805 nm is about 200cm-1). We used diode laser radiation with an output of 25W by contact (0.1, 0.5, 1.0 kg/cm2) and non-contact irradiation methods. In the preliminary experiment with resected porcine stomach, muscularis propriae was intact by the 60s non-contact irradiation or the 8s contact irradiation with contact pressure of 1kg/cm2. In the endoscopic experiment we used 3 dogs. Using conical contact probe, we successfully demonstrated 3cm diameter circular incision with sharp groove in 10 minutes. We could place the snaring wire on the incised groove. Histology of the endoscopically incised canine stomach revealed that the submucosal layer welled up to 6mm in thickness and the bottom of the incision groove reached 1.9mm at deepest below the mucosal muscle. The thickness of the coagulation layer around the incised groove was up to 1.8mm. No damage was seen a the muscularis propriae. We demonstrate easy as well as sure snaring by using our laser incision technique. We think our technique may be available to enhance the efficacy of EMR for early gastric cancer including the lesion over 2cm in diameter.

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

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

    A review of splenic injuries at Cincinnati Children's Hospital Medical Center from July 1978 to June 1980 revealed this form of injury in 29 patients. Treatment without surgery was successful in 21 patients. Seven patients required operation. One patient died shortly after admission of severe associated injuries. All patients admitted with blunt abdominal trauma were initially treated conservatively. If the clinical state improved, after transfusions if necessary, or remained stable and there were no objective signs of further blood loss, conservative therapy was continued. Liver-spleen scans were obtained on an urgent basis to confirm the diagnosis of splenic injury in patients who did not undergo surgery. No complications of treatment without surgery were recognized. The satisfactory outcome in these patients suggests that there is a place for treatment without surgery in some children with splenic injury

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

    The objective was to evaluate abnormalities in the quality of dreams after the use of efavirenz. Ten HIV patients without neuropsychiatric diseases underwent a polisomnography (PSG) study before and after efavirenz treatment, [after 10.4 (SD 5.4) days]. Patients were awoke after REM phases to record their dreams. All patients had therapeutic efavirenz plasma levels. Dreams were recalled in 84% before efavirenz and 43% after efavirenz (p=0.024). There were no differences in the mean number of words per dream before and after efavirenz treatment (61.9 versus 47.5, p=0.115). The proportion of dreams with no neutral emotional content (either pleasant or unpleasant) was 37.5% in the first night and 66.7% in the second night (p=0.046). There were a higher proportion of dreams with no neutral emotional content after efavirenz treatment in this group of patients. However, no longer dreams and no more dreams with negative emotional content were noted. Dream recall was lower after efavirenz treatment. Copyright © 2010 Elsevier España, S.L. All rights reserved.

    Harewood, Gavin C

    2008-09-01

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

These lesions are usually locally aggressive and require complete removal, including the surrounding apparently healthy bone, to provide the best chance of cure. GCTs, as well as other lesions located in the clivus, can nowadays be treated by a minimally invasive fully endoscopic extended endonasal approach. This approach ensures a more direct route to the craniovertebral junction than other possible approaches (transfacial, extended lateral, and posterolateral approaches. The case reported is a clival GCT operated on by an extended endonasal approach that provides another contribution on how to address one of the most feared complications attributed to this approach: a massive bleed due to an internal carotid artery injury.Keywords: clival giant cell tumor, endoscopic endonasal approach, internal carotid artery injury, minimally invasive surgery

    We report a case of gastric bezoar-induced gastric outlet obstruction that was successfully treated with a combination of endoscopic injection and irrigation with Coca Cola. A 73-year-old diabetic woman had a history of perforated peptic ulcer and had received pyloroplasty more than 20 years previously. She had been ingesting Pho Pu Zi (Cordia dichotoma Forst. f.) as an appetizer for 1 month. She presented with epigastric pain, nausea, and vomiting. Upper gastrointestinal endoscopy, performed at a local hospital, showed 2 gastric bezoars in the stomach, and 1 of them impacted at the pylorus. She was referred to our emergency department for removal of the gastric bezoars that were suspected to be causing gastric outlet obstruction. All attempts at endoscopic removal using a polypectomy snare, biopsy forceps and Dormia basket failed. We then injected Coca Cola directly into the bezoar mass, followed by irrigation with Coca Cola. Follow-up endoscopy was performed the next day, which revealed that the gastric bezoars had dissolved spontaneously.

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

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

  5. Endoscopic management of biliary injuries and leaks

    2012-01-01

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

    Esophageal achalasia is a chronic and progressive motility disorder characterized by absence of esophageal body peristalsis associated with an impaired relaxation of lower esophageal sphincter (LES) and usually with an elevated LES pressure, leading to an altered passage of bolus through the esophago-gastric junction. A definitive cure for achalasia is currently unavailable. Palliative treatment options provide only food and liquid bolus intake and relief of symptoms. Endoscopic therapy for a...

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

    The femtosecond (FS) pulse laser incises soft tissues with minimal peripheral damage and is a promising cutting tool for ureteroscopic endoureterotomy of benign ureteral strictures. To evaluate the feasibility of applying the FS laser to ureteroscopic endoureterotomy. A commercial Ti:Sapphire regenerative amplifier system (Coherent, RegA 9050, USA) was used in this study. Normal saline, 5% glucose solution, 4% mannitol solution, distilled water, and a 1% (v/v) suspension of whole blood with each of these solutions were tested for their attenuation rate (AR) of the FS laser's power. Bladder specimens from Sprague-Dawley (SD) rats were used as a surrogate model. The laser incised slots of 2 mm in length at bladder samples using three power grades (5×, 10×, and 20× the threshold power) combined with five effective pulse rates (40, 20, 10, 5, and 2.5 kHz), both in air and in normal saline. After samples were processed with standard hematoxylin-eosin staining procedures, the incision depth and collateral damage range were determined microscopically. The ARs of blood suspensions with each of the three isosmotic solutions were significantly higher than the other five solutions (P laser's cutting depth and the collateral damage were increased with the laser power or power density but the collateral damages were less than 100 µm. Microbubble formation was detected in the liquid environments tested and influenced the effective laser power. Endoscopic application of the FS laser is feasible. Microbubble formation with the laser incision, however, may influence cutting effects. Proposed methods to address these issues include increasing the irrigation rate, using distilled water as irrigation or using gas insufflation instead of irrigation. It is necessary to evaluate these methods, as well as the long-term biologic response to laser incision, on living animal models in endoscopic settings before use on humans.

    To evaluate rebleeding, primary failure (PF) and mortality of patients in whom over-the-scope clips (OTSCs) were used as first-line and second-line endoscopic treatment (FLET, SLET) of upper and lower gastrointestinal bleeding (UGIB, LGIB). A retrospective analysis of a prospectively collected database identified all patients with UGIB and LGIB in a tertiary endoscopic referral center of the University of Freiburg, Germany, from 04-2012 to 05-2016 ( n = 93) who underwent FLET and SLET with OTSCs. The complete Rockall risk scores were calculated from patients with UGIB. The scores were categorized as < or ≥ 7 and were compared with the original Rockall data. Differences between FLET and SLET were calculated. Univariate and multivariate analysis were performed to evaluate the factors that influenced rebleeding after OTSC placement. Primary hemostasis and clinical success of bleeding lesions (without rebleeding) was achieved in 88/100 (88%) and 78/100 (78%), respectively. PF was significantly lower when OTSCs were applied as FLET compared to SLET (4.9% vs 23%, P = 0.008). In multivariate analysis, patients who had OTSC placement as SLET had a significantly higher rebleeding risk compared to those who had FLET (OR 5.3; P = 0.008). Patients with Rockall risk scores ≥ 7 had a significantly higher in-hospital mortality compared to those with scores < 7 (35% vs 10%, P = 0.034). No significant differences were observed in patients with scores < or ≥ 7 in rebleeding and rebleeding-associated mortality. Our data show for the first time that FLET with OTSC might be the best predictor to successfully prevent rebleeding of gastrointestinal bleeding compared to SLET. The type of treatment determines the success of primary hemostasis or primary failure.

    This study investigated the morphometric changes that occur in palatal rugae during orthodontic treatment. The potential impact of these changes on the individuality of the palatal rugae patterns and on the use of palatal rugae patterns in human identification was also explored. Fifty pairs of pre- and post-orthodontic treatment dental casts were used. The palatal rugae patterns were compared between each pre-treatment cast and its post-treatment counterpart to reveal any morphometric changes. In addition, the individuality of the pre- and post-treatment sets of the casts was evaluated. Finally, a matching test of the palatal rugae patterns was performed in which the ability to match each post-treatment cast with its duplicate was compared with the ability to match that post-treatment cast with its pre-treatment counterpart. Statistical analysis of the results revealed the incidence of several morphometric changes, including segmentation (22%); unification (20%); changes in orientation (6%), shape (6%), and length (28%); anteroposterior displacement of the medial (54%) and lateral (60%) end of the ruga; and mediolateral displacement of the medial end of ruga (20%). The individuality of the palatal rugae patterns was confirmed in both pre- and post-treatment sets of casts. Finally, the mean percentage of correct matches was found to be significantly higher when the post-treatment casts were matched with their duplicates compared to when they were matched with their pre-treatment counterparts. The study revealed that Orthodontic treatment induces various morphometric changes in the palatal rugae patterns. These changes may potentially complicate palatal rugae-based human identification.

    2014-12-16

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

    Market research was undertaken to establish the public perception of physiotherapy. Using this market research strategic recommendations for the future marketing of physiotherapy are made within the professional context. Marketing will be used to contribute to changing the public perception of physiotherapy. The market research involved a qualitative study of five focus groups of the general public and one focus group of physiotherapists. The responses from the focus groups were used to construct an appropriate questionnaire for the qualitative study. A random sample of 510 members of the general public were then surveyed. The market research results yielded the following key features: The best known conditions treated by physiotherapists are musculoskeletal. The least known are women and children. Client-centered care is sought. The importance of location gives potential for physiotherapists to capitalise on tailoring to clients in their area. Doctors are important for referral and communication about physiotherapy. Marketing should be used to inform doctors of what physiotherapy has to offer. A marketing orientation has begun within physiotherapy; however, it must 'fit' the culture initially to be successful. A marketing strategy should be developed on national, state and individual levels based on a strategic intent. At the state level, strategies must be responsive to area or regional needs. Marketing needs to target identified market segments such as workers compensation organisations. Individual physiotherapists must promote themselves within their region, particularly to doctors and clients with the use of relationship marketing. Informal presentations to community groups and school students about physiotherapy will increase their profile.

    No consensus exists as to the best endoscopic treatment for Mallory-Weiss syndrome. Endoscopic band ligation is a readily available and easily learned technique. This prospective study evaluated the efficacy and safety of endoscopic band ligation therapy for Mallory-Weiss syndrome. From August 1998 to June 2005, a clinical trial assessed 37 patients with a diagnosis of Mallory-Weiss syndrome who had active bleeding, exposed vessels, or both. Their lesions were treated using endoscopic band ligation. Endoscopic band ligation was successful in 36 of 37 cases, with a follow-up period ranging from 1 to 24 months. The remaining patient had severe liver failure and disseminated intravascular coagulation. The patient bled again at 12 h and subsequently died. Except for this case, no recurrent bleeding, perforation, or other complications occurred. The study results suggest that endoscopic band ligation is an effective, safe, and easily learned procedure for treating upper gastrointestinal bleeding related to Mallory-Weiss syndrome.

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

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

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

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

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

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

    Endoscopic third ventriculostomy is the treatment of choice for non communicating hydrocephalus at our institution. Several factors have been associated with failure of endoscopic third ventriculostomy. The goals of the study have been to evaluate the outcome, the influence of factors theoretically prone to failure of ventriculostomy and the evolution of ventricular size. Fifty-six patients (mean age 48.5 yrs) treated with an endoscopic third ventriculostomy during the period 1997-2002 were analysed retrospectively. Hydrocephalus was classified as acute (68%) and chronic forms. Etiology was classified in space-occupying lesions (59%), primary aqueductal stenosis (34%) and Chiari malformation (7%). The presence of the following factors theoretically prone to failure was considered: age below one year, history of mielomeningocele, cerebrospinal fluid (CSF) infection, intracranial haemorrhage, radiotherapy, craniotomy and previous treatment of hydrocephalus with a shunt. Ventricular size was measured linearly with four ventricular index pre- and postoperatively. The global success rate was 71.4% (mean follow-up 26 months). Endoscopic third ventriculostomy for hydrocephalus secondary to cerebral metastases obstructing CSF pathways was associated with a higher risk of failure (p=0.006). None of the risk factors considered was associated with a higher risk of failure. The evolution of the ventricular size measured with linear methods is associated with outcome. Evans ratio, third ventricle index, cella media index and ventricular score decreased in patients whose outcome is satisfactory and increased in those cases deemed clinical failures (p< 0.05). The risk of failure increases in patients with cerebral metastases close to CSF pathways, likely due to the concurrence of mechanisms other than obstruction. Changes in ventricular size are associated with outcome.

    This study presents a method to identify early esophageal cancer within endoscope using hyperspectral imaging technology. The research samples are three kinds of endoscopic images including white light endoscopic, chromoendoscopic, and narrow-band endoscopic images with different stages of pathological changes (normal, dysplasia, dysplasia - esophageal cancer, and esophageal cancer). Research is divided into two parts: first, we analysis the reflectance spectra of endoscopic images with different stages to know the spectral responses by pathological changes. Second, we identified early cancerous lesion of esophagus by principal component analysis (PCA) of the reflectance spectra of endoscopic images. The results of this study show that the identification of early cancerous lesion is possible achieve from three kinds of images. In which the spectral characteristics of NBI endoscopy images of a gray area than those without the existence of the problem the first two, and the trend is very clear. Therefore, if simply to reflect differences in the degree of spectral identification, chromoendoscopic images are suitable samples. The best identification of early esophageal cancer is using the NBI endoscopic images. Based on the results, the use of hyperspectral imaging technology in the early endoscopic esophageal cancer lesion image recognition helps clinicians quickly diagnose. We hope for the future to have a relatively large amount of endoscopic image by establishing a hyperspectral imaging database system developed in this study, so the clinician can take this repository more efficiently preliminary diagnosis.

    To analyse the long-term results of treatment of posterior urethral disruptions with endoscopic realignment, and to assess the efficacy, simplicity and benefit of this technique. Between 1989 and 2001, thirty six patients were treated by endoscopic realignment for traumatic rupture of the posterior urethra. The analysis of the results took in consideration the quality of urinary stream, the continence and the erectile function. With a mean follow-up of thirty four months (12 to 72 months), the 36 patients treated by endoscopic realignment are continent and urinate with a satisfactory urine output. This result was obtained after internal urethrotomy in 13 patients (36.1%), and after transperineal urethroplasty in two patients. Only 7 patients (19.4%) developed an impotence. The endoscopic realignment can be considered like initial treatment of all post-traumatic rupture of the posterior urethra. This simple and little aggressive technique doesn't compromise the recourse to another type of ulterior treatment and resulted in negligible morbidity. The secondary urethral strictures are short and accessible to an endoscopic urethrotomy.

  11. Techniques and efficacy of flexible endoscopic therapy of Zenker's diverticulum.

    2015-03-16

    Zenker's diverticulum (ZD) is an abnormal hypopharyngeal pouch often presenting with dysphagia. Treatment is often sought with invasive surgical management of the diverticulum being the only mode of definitive therapy. Primarily done by an open transcervical approach in the past, nowadays treatment is usually provided by otolaryngologists using a less invasive trans-oral technique with a rigid endoscope. When first described, this method grew into acceptance quickly due to its similar efficacy and vastly improved safety profile compared to the open transcervical approach. However, the main limitation with this approach is that it may not be suitable for all patients. Nonetheless, progress in the field of natural orifice endoscopic surgery over the last 10-20 years has led to the increase in utilization of the flexible endoscope in the treatment of ZD. Primarily performed by interventional gastroenterologists, this approach overcomes the prior limitation of its surgical counterpart and allows adequate visualization of the diverticulum independent of the patient's body habitus. Additionally, it may be performed without the use of general anesthesia and in an outpatient setting, thus further increasing the utility of this modality, especially in elderly patients with other comorbidities. Today, results in more than 600 patients have been described in various published case series using different techniques and devices demonstrating a high percentage of clinical symptom resolution with low rates of adverse events. In this article, we present our experience with flexible endoscopic therapy of Zenker's diverticulum and highlight the endoscopic technique, outcomes and adverse events related to this minimally invasive modality.

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

    Acute upper gastrointestinal bleeding is a common and potentially life-threatening emergency with substantial mortality. Fresh frozen plasma (FFP), a good source of coagulation factors, might be an ideal injection agent based on its physiologic properties. Therefore, we evaluated the role of FFP as a hemostatic agent in patients with high-risk bleeding peptic ulcers. From August 2015 to April 2016, 108 consecutive patients with high-risk bleeding ulcers were admitted to our university hospital. They were randomly assigned to undergo injection of epinephrine alone (A) or epinephrine plus FFP (B). The primary outcomes assessed were the initial hemostasis, recurrent bleeding, hospital stay, blood transfusion, surgery rate, and 14-day mortality. Initial hemostasis was achieved in 47 of 50 patients (94%) in the Group A and 49 of 50 patients (98%) in the Group B ( P = 0.61). There were no significant differences in the rate of recurrent bleeding between Group A (14%) and Group B (8%) ( P = 0.52). We found no significant differences between Group A and Group B with respect to the surgery rate, bleeding death, procedure-related death, and duration of hospitalization ( P > 0.05). It is concluded the injection of epinephrine alone was equally effective as injection of epinephrine plus FFP to endoscopic hemostasis. Epinephrine alone and epinephrine plus FFP were not different in recurrent bleeding, rate of surgery, blood transfusion, or mortality.

    Clinical parameters of 72 patients who were operated upon for nasal polyps were evaluated as well as biopsy specimens of the mucosa of the middle and inferior turbinates of 41 of these patients. Biopsies were taken at the time of endoscopic sinus surgery (ESS), after 6 months and after 1 year in 23 patients. During the follow-up period the patients were treated with topical corticosteroids (budesonide). At the time of ESS significantly more CD8+ (suppressor/cytotoxic) cells than CD4+ (helper/inducer) cells were found in the middle and inferior turbinates. At 6 months significantly more CD4+ cells were found than at the time of ESS, whereas at 1 year the number of CD4+ cells had decreased and was lower than at 6 months. These data support the theory that the occurrence of nasal polyps is associated with T-cell-dependent disturbances. Clinical evaluation revealed that most of the patients with chronic airway obstruction had better pulmonary functions postoperatively or required less medication for lung disease. These findings show that ESS combined with topical corticosteroids has a positive effect on upper and lower respiratory tract pathology.

    2007-02-01

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

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

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

    Endoscopic ultrasonography is accurate, safe, and cost-effective in diagnosing common bile duct stones, thus suggesting the possibility to avoid invasive endoscopic retrograde cholangiopancreatography. To prospectively evaluate the diagnostic and therapeutic performance of early endoscopic ultrasonography in suspected choledocholithiasis. All consecutive patients presenting to the Emergency Department with suspicion of choledocholithiasis between January 2010 and January 2012 were evaluated and categorized as low, moderate, or high probability of choledocholithiasis, according to accepted criteria. Endoscopic endosonography was carried out within 48 h from the admission and endoscopic retrograde cholangiopancreatography was performed soon in case of confirmed choledocholithiasis. Overall 179 patients were included: 48 (26.8%) were classified as low, 65 (36.3%) as moderate, and 66 (36.9%) as high probability of choledocholithiasis. Of the 86 patients with common bile duct stones at endoscopic endosonography, endoscopic retrograde cholangiopancreatography confirmed the finding in 79 (92%). By multivariate analysis only the common bile duct diameter proved an independent predictor of common bile duct stones. Early endoscopic endosonography is accurate in identifying choledocholithiasis allowing immediate endoscopic treatment and significant spare of unnecessary endoscopic retrograde cholangiopancreatography. This approach can be useful as a triage test to select patients not needing endoscopic retrograde cholangiopancreatography, allowing, in selected cases, their early discharge.

    2009-03-01

    To successfully facilitate the treatment of problem gambling, change processes should be examined in order to identify those variables that differentiate good versus poor treatment outcomes. The current study explored the change facilitating effects of certain characteristics or conditions of an individual being treated: emotional support, instrumental support, emotional awareness, GA involvement, and depressed affect. These conditions were hypothesized to be predictive of a change-oriented mindset (i.e., "resources for change") measured by abstinence self-efficacy, motivation for change, and readiness for change. Participants were 60 outpatients (54.2% male; M age = 46.7 years) with problem gambling recruited from several treatment centres throughout Ontario, Canada. Results indicated that: (1) depressed affect and emotional support seem to influence self-efficacy for abstinence, (2) emotional support alone appears to influence motivation for change, and (3) GA involvement, depressed affect, and emotional awareness, together, seem to influence readiness for change. These findings have implications for promoting change oriented dispositions in problem gambling individuals.

    To investigate the efficacy of endoscopic ablation of Hunner lesions (HLs) in patients with interstitial cystitis (IC) and to find predictors of early recurrence of HLs. A prospective study was performed of patients with Hunner type IC who underwent transurethral ablation. We repeated endoscopic ablation when symptoms and HLs recurred during the follow-up period. The primary endpoint was recurrence-free time. Secondary endpoints were a change in frequency, nocturia, and urgency episodes, and changes in visual analogue scale (VAS) pain scores and other symptom indices at follow-up visits. A total of 72 patients were analysed. The median (range) follow-up period was 29.5 (12.0-50.0) months. After primary ablation treatment, HLs recurred in 75.0% (54/72) of patients, and the median (sd) recurrence-free time was 12.0 (1.6) months. Amongst the 54 patients with recurrence, 50 underwent a second ablation treatment. HLs occurred in 44.0% (22/50) of individuals after the second operation, and the median (sd) recurrence-free time was 18.0 (5.1) months. Lower maximal cystometric capacity (odds ratio 1.01, 95% confidence interval 1.001-1.013) was the predictive factor for early recurrence. There were significant improvements in the VAS pain scores, O'Leary-Sant Interstitial Cystitis Symptom Index and Problem Index, Pelvic Pain and Urgency/Frequency Patient Symptom Scale after treatment (all, P < 0.05). Endoscopic ablation is an effective treatment option for HLs and significantly reduces pain and improves voiding symptoms. Repeat ablation upon recurrence could help symptom control and bladder preservation only if the bladder capacity is maintained. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

    Gastroparesis is a chronic, debilitating condition. We report an experience conducting gastric per-oral endoscopic pyloromyotomy (G-POEM) with objectives to assess clinical efficacy, gastric emptying evolution, and procedural adverse events. This was a clinical pilot series on 12 consecutive patients who underwent G-POEM for refractory gastroparesis in our tertiary center between February 2014 and August 2015. Patients included had severe disease as defined by elevated Gastroparesis Cardinal Symptoms Index (GCSI) score and delayed gastric emptying scintigraphy (GES). G-POEM was performed by mucosal incision upstream the pylorus followed by submucosal tunnel and antropyloromyotomy with subsequent access closure. Efficacy was assessed at 5 days, 1 month, and 3 months, based on GCSI score, and individualizing (Likert scale) the main symptoms (nausea, vomiting, abdominal pain, early satiety, and anorexia). GES was performed 2 months after the procedure. G-POEM was successfully performed in all 12 patients, yielding a technical success rate of 100%. Significant improvements in GCSI were observed: 3.5 ± .8 versus .9 ± .9 (1 month) and 1.1 ± 1.5 (3 months), respectively (P < .001), as well as the severity of main symptoms at 3 months. Clinical efficacy was 85% (10/12). GES normalized in 75% of cases, with improvement of half emptying time (222 ± 90 minutes vs 133 ± 90 minutes; P = .03) and retention at 2 hours (76% ± 20% vs 44% ± 26%; P = .009). There were no adverse events related to the procedure. We report a single-center study evaluating G-POEM for refractory gastroparesis, demonstrating its feasibility, reproducibility, and safety with promising clinical and scintigraphic efficacy.

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

    The Transtheoretical, or Stages of Change Model, has been applied to the investigation of help-seeking related to a number of addictive behaviors. Overall, the model has shown to be very important in understanding the process of help-seeking. However, substance abuse rarely exists in isolation from other health, mental health, and social problems. The present work extends the original Stages of Change Model by proposing "Steps of Change" as they relate to entry into substance abuse treatment programs for women. Readiness to make life changes in four domains-domestic violence, HIV sexual risk behavior, substance abuse, and mental health-is examined in relation to entry into four substance abuse treatment modalities (12-step, detoxification, outpatient, and residential). The Steps of Change Model hypothesizes that help-seeking behavior of substance-abusing women may reflect a hierarchy of readiness based on the immediacy, or time urgency, of their treatment issues. For example, women in battering relationships may be ready to make changes to reduce their exposure to violence before admitting readiness to seek substance abuse treatment. The Steps of Change Model was examined in a sample of 451 women contacted through a substance abuse treatment-readiness program in Los Angeles, California. A series of logistic regression analyses predict entry into four separate treatment modalities that vary. Results suggest a multidimensional Stages of Change Model that may extend to other populations and to other types of help-seeking behaviors.

    The aim of this study was to report and show the technique, results, and complications of combined endoscopic and intraoperative magnetic resonance imaging (IMRI) surgical treatment of pituitary disease from both a technical and a surgical perspective. We performed a retrospective chart review of 10 endoscopic, endonasal resections of 10 pituitary macroadenomas using the Polestar N-10 IMRI system in a tertiary health care facility. The patient demographics, tumor measurements, and postoperative symptoms and complications were assessed. The effect of the magnetic field on the video screen, the image quality of the IMRI images, and IMRI detection of residual tumor were evaluated also. IMRI images were obtained in all cases and were of sufficiently high quality to indicate adequate decompression of the optic chiasm and the removal of all suprasellar tumor. However, there was significant distortion of the video monitor regardless of the viewing angle. This was overcome with a wall-mounted plasma screen. Residual tumor was found with IMRI and resected endoscopically in three cases. In two other cases, suspected residual tumor on IMRI was examined endoscopically and found to be a normal postoperative change. In two cases no tumor was seen on the IMRI. Five patients who had preoperative progressive visual loss preoperatively improved postresection and two patients who had increased insulin growth factor 1 preoperatively normalized postoperatively. No delayed cerebrospinal fluid leaks or any other complications occurred. Combining intraoperative endoscopy and IMRI is an effective surgical modality for pituitary surgery. Each technology provides complimentary information, which can assist the surgeon in safely maximizing the extent of resection.

    Full Text Available Objective : Impaction of the third molar tooth mandibular is often found in patients with orthodontic treatment. In orthodontic treatment, extraction cases of impaction of the third molar tooth are usually performed, but the patients often refuse this extraction. Extraction of premolar has a good effect on the third molar mandibular angulation during treatment. Material and Methods : This study is a retrospective clinical study with descriptive analytic to find out the effect of the first mandibular premolar tooth extraction to angulation change of the third molar mandibular in orthodontic treatment with a standard edgewise method. Angulation change was performed by comparing the third molar mandibular angulation before and after orthodontic treatment with panoramic radiographs. Angulation of the third molar tooth mandibular was calculated from the angle formed between the long axis of the tooth with the reference line infraorbita. Results : The sample comprised 60 of impacted mandibular third molar region of the left and right regions of 30 patients who had been treated declared cured in clinic of orthodontic specialist of Dentistry Faculty Padjadjaran University. The sample was divided into three (3 groups of patients before treatment angulation of the third molar tooth mandibular under 300, 300 to 600 and above 60o, then measured change of angulation and observed whether it increased, fixed or decreased. Results were analyzed by T- test and Wilcoxon test showed that there was a significant change in angulation of the third molar mandibular in orthodontic treatment with the first premolar tooth mandibular extraction. Conclusion : This study is that the first premolar tooth mandibular extraction affects the angulation of the third molar tooth mandibular after orthodontic treatment.

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

    2007-01-01

    We compared injected volume of dextranomer/hyaluronic acid with sonographic volumes obtained 2 weeks to 36 months postoperatively to evaluate the amount of volume retention with time and to correlate volume retention with voiding cystourethrogram results. We retrospectively reviewed sonographic volume measurements of dextranomer/hyaluronic acid implants in children at 2 weeks to 36 months postoperatively. Hydronephrosis and percentage of dextranomer/hyaluronic acid retained at each interval were recorded. Average change in volume at each interval was used to compare volume retention with time. The fraction of dextranomer/hyaluronic acid retained was compared to voiding cystourethrogram at 3 months. No patient had new or worsened hydronephrosis. Volumetric data were available for 296, 150, 42, 23 and 20 ureters at 2, 3, 6 and 12 weeks, and 24 to 36 months postoperatively, respectively. Percentage of dextranomer/hyaluronic acid retained was 79% at 2, 74% at 3, 70% at 6 and 78% at 12 weeks, and 65% at 24 to 36 months (p >0.05). While there was no significant difference in mean volume retained between cures (74%) and treatment failures (67%), the 94% cure rate with mega-implants (greater than anticipated volume retention) was higher than that with micro-implants (75%) or nonvisualized implants (70%). After the initial volume reduction at 2 weeks dextranomer/hyaluronic acid implants remained durable with insignificant volume reduction for up to 36 months postoperatively. Although overall mean volume retention did not correlate with cure, mega-implants were associated with high cure rates and may justify elimination of postoperative voiding cystourethrography.

    Interventional endoscopic ultrasonography (EUS) based on EUS-guided fine-needle aspiration has rapidly spread as a minimally invasive procedure. Especially in patients with failed endoscopic retrograde cholangiopancreatography, EUS-guided biliary intervention is reported to be useful as salvage therapy. EUS-guided biliary interventions are carried out using three techniques: EUS-guided bilioenteric anastomosis, EUS-guided rendezvous procedure, and EUS-guided antegrade treatment. Although interventional EUS is not yet a standardized procedure, there have been recent advances in this field that address various biliary diseases. Here, we summarize the indications, techniques, clinical results of previous studies, and future perspectives. PMID:26327757

    2016-01-01

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

    1998-01-01

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

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

    To evaluate the efficacy and safety of transpapillary papilloplasty in patients with choledocholithiasis. All endoscopic retrograde cholangiopancreatography (ERCP) procedures performed at Hospital Ana Costa, in the city of Santos, Brazil, over the last five years were retrospectively evaluated using the hospital's information database. The success of the procedure and complications due to residual calculi, pancreatitis, bleeding and perforation were evaluated. From January 2010 to May 2014, 1860 ERCP procedures were performed. Fifty-five patients were evaluated here. Their ages ranged from 12 to 98 years (mean, 66.3; standard deviation, 19.34; median, 71). Thirty-two patients (58.2%) were women. Sixteen (29.1%) presented giant choledocholithiasis, with calculi larger than 12 mm. Twenty-seven (49.1%) had mul-tiple choledocholithiasis. In view of the therapeutic efficacy and low complication rate among our patients, we can conclude that endoscopic papilloplasty is a safe and effective method for endoscopic treatment of choledocolithiasis in selected cases.

    2016-07-01

    Treatment of choledocholithiasis and cholelithiasis in patients with cirrhosis often requires diagnostic and therapeutic endoscopy such as endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP). Patients with underlying cirrhosis may have coagulopathy, hepatic encephalopathy, ascites and other comorbidities associated with cirrhosis that can make endoscopic therapy challenging and can be associated with a higher risk of adverse events. Given the unique derangements of physiologic parameters associated with cirrhosis this population requires a truly multifaceted and multidisciplinary understanding between therapeutic endoscopists, hepatologists and anesthesiologists. For therapeutic endoscopists, it is critical to be aware of the specific issues unique to this population of patients to optimize outcomes and avoid adverse events. The epidemiology of gallstone disease, the diagnostic and therapeutic approach to patients with varying degree of hepatic dysfunction, and a review of the available literature in this area are presented.

    2015-06-01

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

    Endoscopic findings of the background gastric mucosa are important in the Helicobacter pylori-seroprevalent population. It is strongly correlated not only with the risk of gastric cancer, but also with the excretion ability of gastric mucosa cells. In noninfected subjects, common endoscopic findings are regular arrangement of collecting venules, chronic superficial gastritis, and erosive gastritis. In cases of active H. pylori infection, nodularity on the antrum, hemorrhagic spots on the fundus, and thickened gastric folds are common endoscopic findings. The secreting ability of the gastric mucosa cells is usually intact in both noninfected and actively infected stomachs, and the intragastric condition becomes hyperacidic upon inflammation. Increased serum pepsinogen II concentration correlates well with active H. pylori infection, and also indicates an increased risk of diffuse-type gastric cancer. In chronic inactive H. pylori infection, metaplastic gastritis and atrophic gastritis extending from the antrum (closed-type chronic atrophic gastritis) toward the corpus (open-type chronic atrophic gastritis) are common endoscopic findings. The intragastric environment is hypoacidic and the risk of intestinal-type gastric cancer is increased in such conditions. Furthermore, there is a decrease in serum pepsinogen I concentration when the secreting ability of the gastric mucosa cells is damaged. Serologic and endoscopic changes that occur upon H. pylori infection are important findings for estimating the secreting ability of the gastric mucosa cells, and could be applied for the secondary prevention of gastric cancer.

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

    As part of a hospital clinical research program on endoscopic curative treatment for early epithelial neoplastic lesions of the gastrointestinal tract, a new hospital sterile and non-pyrogenic preparation of fructose (5%)-glycerol (10%) was realized. Under pharmaceutical legislation, the provision of this hospital preparation involves of aseptic process validation and achieve a stability study. After the aseptic process validation with Mediafill Test, the preparation was made under aseptic conditions associated with a sterilizing filtration according to the good practices preparation. Prepared flexible bags (100mL of solution) were stored for one year in a climatic chamber (25±2°C). To assess stability, the physicochemical controls (fructose concentration, glycerol concentration, hydroxy-methyl-5 furfural [5-HMF] concentration, sodium concentration, pH measure, osmolality and sub-visible particles count) and microbiological (bioburden, bacterial endotoxin and sterility) were performed at regular intervals for one year. Neither significant decrease of fructose concentration, glycerol concentration and sodium concentration nor pH, 5-HMF, osmolality variations out of specifications were observed for one year. The sub-visible particles count, the bacterial endotoxin and sterility were in accordance with the European pharmacopoeia attesting limpidity, apyrogenicity and sterility of this injectable preparation. The hospital preparation was stable over one year at 25±2°C, ensuring safe administration in humans within the framework of this clinical research. Copyright © 2014 Elsevier Masson SAS.

    Endoscopes have been commonly used in transsphenoidal surgery to treat pituitary tumors, to compensate for the narrow surgical field. Although many navigation systems have been introduced for neurosurgical procedures, there have been few reports of navigation systems for endoscopic operations. This report presents our recently developed, endoscopic, augmented reality (AR) navigation system. The technology is based on the principles of AR environment technology. The system consisted of a rigid endoscope with light-emitting diodes, an optical tracking system, and a controller. The operation of the optical tracking system was based on two sets of infrared light-emitting diodes, which measured the position and orientation of the endoscope relative to the patient's head. We used the system during endonasal transsphenoidal operations to treat pituitary tumors in 12 recent cases. Anatomic, "real," three-dimensional, virtual images of the tumor and nearby anatomic structures (including the internal carotid arteries, sphenoid sinuses, and optic nerves) were superimposed on real- time endoscopic live images. The system also indicated the positions and directions of the endoscope and the endoscopic beam in three-dimensional magnetic resonance imaging or computed tomographic planes. Furthermore, the colors of the wire-frame images of the tumor changed according to the distance between the tip of the endoscope and the tumor. These features were superior to those of conventional navigation systems, which are available only for operating microscopes. The endoscopic AR navigation system allows surgeons to perform accurate, safe, endoscope-assisted operations to treat pituitary tumors; it is particularly useful for reoperations, in which midline landmarks may be absent. We consider the AR navigation system to be a promising tool for safe, minimally invasive, endonasal, transsphenoidal surgery to treat pituitary tumors.

    Full Text Available Abstract Most Spanish prisons provide specialised treatment for incarcerated sex offenders, both rapists and child molesters. This treatment is a cognitive-behavioural intervention that has shown relative effectiveness in previous research. With regard to offenders’ rehabilitation, recidivism assessments are necessary as a final measure of treatment effectiveness. However, the evaluation of recidivism by itself does not provide sufficient information on the treatment process and the specific effects that treated subjects could undergo. This paper aims to analyse the therapeutic effectiveness of psychological treatment provided to rapists (in general, males sentenced for committing a sexual offence against women. To this aim, a group of treated rapists (N=153 serving a sentence in prison was analysed. Using a specially designed scale (PASSO, the global therapeutic change and ten specific variables (including assertiveness, readiness to change, cognitive distortions, impulsivity, etc. were assessed. The within-subjects comparison showed that treated sex offenders improved, in therapeutic terms, globally as well as in most of the specific variables assessed (improvements not experimented by the control group. Also, different therapeutic subscales showed relevant associations between them. The findings regarding treatment effectiveness are discussed.

    The emergence of Plasmodium falciparum resistance to most anti-malarial compounds has highlighted the urgency to develop new drugs and to clarify the mechanisms of anti-malarial drugs currently used. Among them, doxycycline is used alone for malaria chemoprophylaxis or in combination with quinine or artemisinin derivatives for malaria treatment. The molecular mechanisms of doxycycline action in P. falciparum have not yet been clearly defined, particularly at the protein level. A proteomic approach was used to analyse protein expression changes in the schizont stage of the malarial parasite P. falciparum following doxycycline treatment. A comparison of protein expression between treated and untreated protein samples was performed using two complementary proteomic approaches: two-dimensional fluorescence difference gel electrophoresis (2D-DIGE) and isobaric tagging reagents for relative
