Background/Aims: Surgery is the mainstay of treatment for cholecystitis. However, gallbladder stenting (GBS) has shown promise in debilitated or high-risk patients. Endoscopic transpapillary GBS and endoscopic ultrasound-guided GBS (EUS-GBS) have been proposed as safe and effective modalities for gallbladder drainage. Methods: Data from patients with cholecystitis were prospectively collected from August 2004 to May 2013 from two United States academic university hospitals and analyzed retrospectively. The following treatment algorithm was adopted. Endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy and cystic duct stenting was initially attempted. If deemed feasible by the endoscopist, EUS-GBS was then pursued. Results: During the study period, 139 patients underwent endoscopic gallbladder drainage. Among these, drainage was performed in 94 and 45 cases for benign and malignant indications, respectively. Successful endoscopic gallbladder drainage was defined as decompression of the gallbladder without incidence of cholecystitis, and was achieved with ERCP and cystic duct stenting in 117 of 128 cases (91%). Successful endoscopic gallbladder drainage was also achieved with EUS-guided gallbladder drainage using transmural stent placement in 11 of 11 cases (100%). Complications occurred in 11 cases (8%). Conclusions: Endoscopic gallbladder drainage techniques are safe and efficacious methods for gallbladder decompression in non-surgical patients with comorbidities.

Background/Aims: Performing endoscopic retrograde cholangiopancreatography (ERCP) in patients who have undergone Roux-en-Y gastric bypass (RYGB) is challenging. Standard ERCP and enteroscopy-assisted ERCP are associated with limited success rates. Laparoscopy- or laparotomy-assisted ERCP yields improved efficacy rates, but with higher complication rates and costs. We present the first multicenter experience regarding the efficacy and safety of endoscopic ultrasound (EUS)-directed transgastric ERCP (EDGE) or EUS. Methods: All patients who underwent EDGE at two academic centers were included. Clinical success was defined as successful ERCP and/or EUS through the use of lumen-apposing metal stents (LAMS). Adverse events related to EDGE were separated from ERCP- or EUS-related complications and were defined as bleeding, stent migration, perforation, and infection. Results: Sixteen patients were included in the study. Technical success was 100%. Clinical success was 90% (n=10); five patients were awaiting maturation of the fistula tract prior to ERCP or EUS, and one patient had an aborted ERCP due to perforation. One perforation occurred, which was managed endoscopically. Three patients experienced stent dislodgement; all stents were successfully repositioned or bridged with a second stent. Ten patients (62.5%) had their LAMS removed. The average weight change from LAMS insertion to removal was negative 2.85 kg. Conclusions: EDGE is an effective, minimally invasive, single-team solution to the difficulties associated with ERCP in patients with RYGB.

Peroral Endoscopic Myotomy: Establishing a New Program
Nikhil A. Kumta,Shivani Mehta,Prashant Kedia,Kristen Weaver,Reem Z. Sharaiha,Norio Fukami,Hitomi Minami,Fernando Casas,Monica Gaidhane,Arnon Lambroza,Michel Kahaleh 대한소화기내시경학회 2014 Clinical Endoscopy Vol.47 No.5
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.
