POEM is safe and effective for patients with achalasia who were not treated successfully by prior HM. Although the rate of clinical success in patients with prior HM is lower than in those without prior HM, the safety profile of POEM is comparable between groups.

BFMS appear to be superior to MPS for EUS-guided WON drainage in terms of clinical success, number of DEN sessions, adverse events, need for salvage surgery and hospital stay.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) and biliary stenting fails in 5-10% patients of malignant biliary obstruction because papilla is inaccessible. Percutaneous transhepatic biliary drainage (PTBD) is an accepted alternative. Endosonography-guided biliary drainage (EUS-BD) has been described recently. Aim: To compare success rates and complications of EUS-BD and PTBD internal stenting. Methods: This retrospective study included failed ERCP in inoperable malignant biliary obstruction due to inaccessible papilla undergoing PTBD or EUS-BD. Percutaneous transhepatic cholangiography guided/EUS-guided rendezvous procedures were excluded. When PTBD internal stenting failed, external drainage was performed. EUS-BD was performed using either intra-or extrahepatic approach, and stents were placed by transmural (choledocho-duodenostomy or hepaticogastrostomy) or antegrade approach. Self-expandable metallic stents or plastic stents were placed in both groups. Success of internal stenting and complications were compared using t-test and chi-squared test. Results: Retrospective review of 6 years of records (2005)(2006)(2007)(2008)(2009)(2010)(2011) revealed 50 patients meeting the required criteria. EUS-BD was attempted in 25 and PTBD in 26 patients (one crossover from EUS-BD to PTBD). Internal stenting was technically and clinically successful in 23/25 (92%) EUS-BD vs. 12/26 (46%) PTBD (p < 0.05). External catheter drainage was performed in remaining 14 PTBD patients. Complications occurred in 5/25 (20%) EUS-BD (one major, four minor) and in 12/26 (46%) PTBD (four major, eight minor; p < 0.05). Late stent occlusion occurred in one EUS-BD and three PTBD. Conclusions: In this retrospective study comparing success and complications of EUS-BD and PTBD in patients with inoperable malignant biliary obstruction and inaccessible papilla, EUS-BD was found superior to PTBD for both comparators.

BackgroundBoth long-term proton pump inhibitor (PPI) use and surgical fundoplication have potential drawbacks as treatments for chronic gastroesophageal reflux disease (GERD). This multi-center, prospective study evaluated the clinical experiences of 69 patients who received an alternative treatment: endoscopic anterior fundoplication with a video- and ultrasound-guided transoral surgical stapler.MethodsPatients with well-categorized GERD were enrolled at six international sites. Efficacy data was compared at baseline and at 6 months post-procedure. The primary endpoint was a ≥50 % improvement in GERD health-related quality of life (HRQL) score. Secondary endpoints were elimination or ≥50 % reduction in dose of PPI medication and reduction of total acid exposure on esophageal pH probe monitoring. A safety evaluation was performed at time 0 and weeks 1, 4, 12, and 6 months.Results66 patients completed follow-up. Six months after the procedure, the GERD-HRQL score improved by >50 % off PPI in 73 % (48/66) of patients (95 % CI 60–83 %). Forty-two patients (64.6 %) were no longer using daily PPI medication. Of the 23 patients who continued to take PPI following the procedure, 13 (56.5 %) reported a ≥50 % reduction in dose. The mean percent of total time with esophageal pH <4.0 decreased from baseline to 6 months (P < 0.001). Common adverse events were peri-operative chest discomfort and sore throat. Two severe adverse events requiring intervention occurred in the first 24 subjects, no further esophageal injury or leaks were reported in the remaining 48 enrolled subjects.ConclusionsThe initial 6-month data reported in this study demonstrate safety and efficacy of this endoscopic plication device. Early experience with the device necessitated procedure and device changes to improve safety, with improved results in the later portion of the study. Continued assessment of durability and safety are ongoing in a three-year follow-up study of this patient group.
