BACKGROUND AND STUDY AIMS Secure transluminal closure is the most fundamental prerequisite for the safe introduction of natural orifice transluminal endoscopic surgery (NOTES). The aim was to compare acute strength of various gastrotomy closure techniques in an in vitro porcine stomach model by assessing leak pressures. METHODS Standardized gastrotomies(More)
BACKGROUND Surgical repair of endoscopic perforations of the GI tract used to be the standard, but immediate, secure endoscopic closure has become an attractive alternative treatment with the potential to reduce morbidity and mortality. OBJECTIVE We aimed to perform a systematic review of the medical literature on endoscopic closure of acute iatrogenic(More)
BACKGROUND Ileocolic resection for Crohn's disease can be performed entirely laparoscopically. However, an incision is needed for specimen extraction. This prospective observational study assessed the feasibility of endoscopic transcolonic specimen removal. METHODS Endoscopic specimen removal was attempted in a consecutive series of ten patients scheduled(More)
We performed a systematic review to assess the outcome of endoscopic transluminal necrosectomy in necrotising pancreatitis with additional focus on indication, disease severity, and methodological quality of studies. We searched the literature published between January 2005 and June 2013. Cohorts, including patients with (infected) necrotising pancreatitis,(More)
BACKGROUND Surgical management of pancreatic necrosis is associated with significant morbidity and mortality. Several weeks after an episode of a necrotizing pancreatitis, necrosis can become organized. By the time necrosis becomes organized, endoscopic therapy has the potential to offer an alternative treatment to surgery. OBJECTIVE To evaluate the(More)
Secure transluminal closure remains the most fundamental barrier to safe translation of transgastric natural orifice transluminal endoscopic surgery (NOTES) procedures to humans. Obtaining optimal critical view of safety (CVS) is a prerequisite to performing cholecystectomy avoiding common bile duct injury. (1) To evaluate feasibility and safety of hybrid(More)
BACKGROUND AND STUDY AIMS Secure transluminal closure remains a fundamental barrier to clinical introduction of natural orifice transluminal endoscopic surgery (NOTES). Current NOTES closure modalities either do not provide secure closure or are too challenging to apply in vivo. The aims of this study were to evaluate gastric closure using the(More)
BACKGROUND EUS-guided drainage of pancreatic fluid collections (PFCs) is commonly performed with oblique-viewing echoendoscopes. However, accessing the PFC under an oblique angle can make drainage difficult. These difficulties might be overcome by using a forward-viewing echoendoscope. OBJECTIVE To compare endoscopic PFC drainage with an oblique-viewing(More)
BACKGROUND Infected necrotising pancreatitis is a potentially lethal disease that nearly always requires intervention. Traditionally, primary open necrosectomy has been the treatment of choice. In recent years, the surgical step-up approach, consisting of percutaneous catheter drainage followed, if necessary, by (minimally invasive) surgical necrosectomy(More)
BACKGROUND AND STUDY AIM Colonic perforation is a serious complication of colonoscopy, with surgical repair usually indicated. The aim was to compare acute strength of various endoscopic colonic closure techniques by assessing air leak pressures in a previously described ex vivo experimental apparatus. METHODS Standardized colonic perforations were(More)
