Background and Aims null Lumen-apposing metal stents (LAMSs) are a novel class of devices that have expanded the spectrum of endoscopic GI interventions. LAMSs with their dumbbell configuration, short saddle length, and large inner luminal diameter provide favorable stent characteristics to facilitate anastomosis formation between the gut lumen and adjacent structures. null null null Methods null The MEDLINE database was searched through April 2021 for articles related to LAMSs by using addition...
ABSTRACT BACKGROUND and AIMS Major limitations of conventional EMR (C-EMR) include high rates of polyp recurrence and low en-bloc resection rates, especially for lesions >20 mm in size. Underwater EMR (U-EMR) has emerged as an alternate technique for en-bloc resection of larger lesions. We conducted a systematic review and meta-analysis comparing efficacy and safety of the 2 techniques. METHODS Multiple databases were searched through June 2020 for studies that compared outcomes of U-EMR and C-E...
Abstract null null When performed appropriately and safely, esophagogastroduodenoscopy (EGD) is an invaluable tool for diagnosing and monitoring a range of upper gastrointestinal disorders and cancers. With more than 6 million EGDs being performed in the United States and reports of missed upper GI (UGI) lesions, both experienced and budding endoscopists should keep a number of essential considerations in mind when performing an EGD, and that starts with obtaining a thorough patient medical hist...
Abstract null null Background and aims null Risk-stratified endoscopic screening (RSES) has been suggested to improve screening efficiency. We aimed to assess the cost-effectiveness of RSES and identify the optimal risk score thresholds for once in a lifetime esophageal cancer (EC) screening in high-risk areas of China. null null null Methods null From a healthcare system perspective, a Markov model was constructed to compare the cost-effectiveness of 13 RSES strategies (under different score th...
