Background: Peroral endoscopic myotomy (POEM) is a well-established endoscopic treatment for achalasia, utilizing an endoscopic knife for dissection. Recently, new knives with an integrated water-jet (WJ) function have been introduced. This study aims to compare the technical, perioperative, and late postoperative outcomes between WJ knives and conventional (C) knives, which lack the WJ function, through a pairwise meta-analysis of published comparative studies.

Background And Aims: Several studies have hypothesized that sparing the oblique/sling fibers during posterior peroral endoscopic myotomy (POEM) may reduce the incidence of gastroesophageal reflux disease (GERD) and reflux esophagitis without compromising the established safety and efficacy of the procedure. This study compares perioperative, postoperative motility-related, and postoperative GERD-related outcomes between posterior oblique/sling fibers-sparing POEM (OFS-POEM) and conventional posterior POEM through a pairwise meta-analysis of comparative studies.
Methods: We conducted a systematic literature review following PRISMA guidelines to identify articles directly comparing posterior OFS-POEM with conventional posterior POEM.
Stent-induced ductal change is a complication of endoscopic treatment of the main pancreatic duct in chronic pancreatitis. Most previous reports have been based on morphological duct changes observed via pancreatography. Here, we describe a case of stent-induced ductal change in which the course of the mucosal changes was observed through peroral pancreatoscopy with a videoscopy.

Background: Achalasia is a primary esophageal motility disorder, which shows impaired relaxation of the lower esophageal sphincter (LES) and the absence of peristalsis, leading to dysphagia, weight loss, and chest pain. In recent years, peroral endoscopic myotomy (POEM) has become a popular method for treating achalasia. However, the effectiveness and safety of full-thickness myotomy (FTM) versus circular muscle myotomy (CMM) in POEM require further investigation.

Background And Aims: Peroral endoscopic myotomy (POEM) has become the treatment of choice for achalasia. However, the impact of myotomy length on POEM outcomes remains unclear. We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing the outcomes of short versus standard-length myotomy in achalasia patients.
