Novel classification system for walled-off necrosis: a step toward standardized nomenclature and risk-stratification framework
The optimal therapeutic approach for walled-off necrosis (WON) is not fully understood, given the lack of a validated classification system. We propose a novel and robust classification system based on radiologic and clinical factors to standardize the nomenclature, provide a framework to guide comparative effectiveness trials, and inform the optimal WON interventional approach.Impact of trimodality sampling on detection of malignant biliary strictures compared with patients with primary sclerosing cholangitis
Malignant biliary strictures can be difficult to diagnose, with up to 20% considered indeterminate after initial tissue sampling. This study aimed to determine the performance characteristics of transpapillary biopsy sampling (TPB) and fluorescence in situ hybridization (FISH) in isolation or in combination with standard brush cytology (BC) in patients who received trimodality sampling for biliary strictures.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.Transpapillary gallbladder stent placement for long-term therapy of acute cholecystitis
Select patients with acute cholecystitis (AC) are poor candidates for cholecystectomy. ERCP-guided transpapillary gallbladder (GB) drainage (ERGD) is one modality for nonoperative management of AC in these patients. Our primary aim was to evaluate long-term success of destination ERGD. Secondary aims were the rate of technical and clinical success, number of repeat procedures, rate of adverse events, and risk factors for recurrent AC.
