Covered versus uncovered double bare self-expandable metal stent for palliation of unresectable extrahepatic malignant biliary obstruction: a randomized controlled multicenter trial
In a recent randomized controlled trial, a double bare metal stent (DBS) showed better stent patency than single-layer metal stents. However, clear evidence comparing the efficacy of uncovered (UCDBS) and partially covered (PCDBS) DBSs for distal malignant biliary obstruction (MBO) is lacking. Therefore, we compared the clinical outcomes including stent patency of UCDBSs versus PCDBSs.Clip closure to prevent adverse events after EMR of proximal large nonpedunculated colorectal polyps: meta-analysis of individual patient data from randomized controlled trials
After EMR, prophylactic clipping is often performed to prevent clinically significant post-EMR bleeding (CSPEB) and other adverse events (AEs). Prior evidence syntheses have lacked sufficient power to assess clipping in relevant subgroups or in nonbleeding AEs. We performed a meta-analysis of individual patient data (IPD) from randomized trials assessing the efficacy of clipping to prevent AEs after EMR of proximal large nonpedunculated colorectal polyps (LNPCPs) ≥20 mm.EUS-directed transgastric interventions in Roux-en-Y gastric bypass anatomy: a multicenter experience
Placement of a lumen-apposing metal stent (LAMS) between the gastric pouch and the excluded stomach allows for EUS-guided transgastric interventions (EDGIs) in patients with Roux-en-Y gastric bypass (RYGB). Although EUS-guided transgastric ERCP (EDGE) outcomes have been reported, data are scant on other endoscopic interventions. We aimed to evaluate the outcomes and safety of EDGIs.Comparison of distal primary obesity surgery endolumenal techniques for the treatment of obesity (with videos)
Distal primary obesity surgery endolumenal (POSE) procedures involve plication of the gastric body, sparing the fundus. We aim to assess the efficacy of distal POSE procedures and to compare plication techniques (single-helix vs double-helix approaches).Efficacy of narrow-band imaging during peroral cholangioscopy for predicting malignancy of indeterminate biliary strictures (with videos)
Direct peroral cholangioscopy (POC) can be useful when combined with narrow-band imaging (NBI) to explore the etiologies of indeterminate biliary strictures. We evaluated the efficacy of NBI compared with that of conventional white-light imaging (WLI) during POC diagnosis of indeterminate biliary strictures.Endoscopic gastric plication for the treatment of weight regain after Roux-en-Y gastric bypass (with video)
Gastric plication involves inverting the stomach with tissue anchor placement to achieve serosa-to-serosa apposition. One potential application of gastric plication is the treatment of weight regain after Roux-en-Y gastric bypass (RYGB), a procedure also known as plication transoral outlet reduction (P-TORe). This study aims to assess technical feasibility, safety, and efficacy of P-TORe.Comparative diagnostic performance of end-cutting fine-needle biopsy needles for EUS tissue sampling of solid pancreatic masses: a network meta-analysis
Evidence is limited on the comparative diagnostic performance of newer end-cutting fine-needle biopsy (FNB) needles for tissue sampling of pancreatic masses. We performed a systematic review with network meta-analysis to compare the diagnostic accuracy of available FNB needles for sampling of solid pancreatic lesions.Novel classification for adverse events in GI endoscopy: the AGREE classification
Standardized registration and evaluation of adverse events (AEs) are essential to assess the safety of endoscopic procedures. We propose a novel classification system, named adverse events in GI endoscopy (AGREE), adapted from a widely accepted surgical tool.Initial multicenter experience using a novel endoscopic tack and suture system for challenging GI defect closure and stent fixation (with video)
Closure of endoscopic resection defects can be achieved with through-the-scope clips, over-the-scope clips, or endoscopic suturing. However, these devices are often limited by their inability to close large, irregular, and difficult-to-reach defects. Thus, we aimed to assess the feasibility and safety of a novel through-the-scope, suture-based closure system developed to overcome these limitations.Safety and efficacy of a novel resection system for direct endoscopic necrosectomy of walled-off pancreas necrosis: a prospective, international, multicenter trial
Direct endoscopic necrosectomy (DEN) of walled-off pancreatic necrosis (WOPN) lacks dedicated instruments and requires repetitive and cumbersome procedures. This study evaluated the safety and efficacy of a new powered endoscopic debridement (PED) system designed to simultaneously resect and remove solid debris within WOPN.Safety and efficacy of a novel electrocautery-enhanced lumen-apposing metal stent in interventional EUS procedures (with video)
Electrocautery-tip lumen-apposing metal stents (EC-LAMSs) have extended the indications of therapeutic EUS. We aimed to retrospectively evaluate safety and technical and clinical success of a newly developed EC-LAMS, the Hot-Spaxus (Taewoong Medical Co, Gimpo, Korea), for various EUS-guided procedures.Classification, outcomes, and management of misdeployed stents during EUS-guided gastroenterostomy
Stent misdeployment (SM) has hindered the dissemination of EUS-guided gastroenterostomy (EUS-GE) for gastric outlet obstruction (GOO) management. We aimed to provide a classification system for SM during EUS-GE and study clinical outcomes and management accordingly.Single-use duodenoscope for ERCP performed by endoscopists with a range of experience in procedures of variable complexity
Expert endoscopists previously reported ERCP outcomes for the first commercialized single-use duodenoscope. We aimed to document usability of this device by endoscopists with different levels of ERCP experience.Endoscopic versus surgical gastrojejunal revision for weight regain in Roux-en-Y gastric bypass patients: 5-year safety and efficacy comparison
An enlarged gastrojejunal anastomosis (GJA) is associated with weight regain after Roux-en-Y gastric bypass (RYGB) and can be corrected with endoscopic or surgical revision; however, there has been no direct comparison between techniques. This study aims to compare serious adverse event (AE) rates and weight loss profiles between endoscopic and surgical revisional techniques over a 5-year period.Single-pass 1-needle actuation versus single-pass 3-needle actuation technique for EUS-guided liver biopsy sampling: a randomized prospective trial (with video)
Several reports have validated EUS-guided liver biopsy sampling (EUS-LB) as safe and effective. Nineteen-gauge EUS aspiration (FNA) or core (fine-needle biopsy [FNB]) needles are used, but different needle techniques can yield variable outcomes. Some data show that 1 pass (single liver puncture) with 1 actuation (1 to-and-fro needle movement) may be enough to obtain a satisfactory specimen. However, there has not been a head-to-head comparison of single versus multiple needle actuations for EUS-LB.Outcomes of a hybrid technique using EMR and endoscopic full-thickness resection for polyps not amenable to standard techniques (with video)
The full-thickness resection device (FTRD) offers a safe and effective approach for resection of complex colorectal lesions but is limited to lesions <2 cm in size. A hybrid approach—combining EMR with the FTRD—significantly expands the pool of lesions amenable to this technique; however, its safety and efficacy has not been well established.
