Peroral endoscopic myotomy as a treatment for Killian-Jamieson diverticulum (KJ-POEM).

Killian-Jamieson diverticulum (KJD) is a rare type of esophageal diverticulum that occurs in a specific area called the Killian-Jamieson space. Although surgery has been the conventional treatment for symptomatic KJD, minimally invasive endoscopic techniques, particularly Killian-Jamieson per-oral endoscopic myotomy (KJ-POEM), have emerged as an alternative. The aim of the study was to evaluate the effectiveness and safety of KJ-POEM in treating KJD.

Short esophageal myotomy versus standard myotomy for treatment of sigmoid-type achalasia: results of an international multicenter study.

Background And Aims: Patients with sigmoid-type achalasia can be challenging to treat with peroral endoscopic myotomy (POEM). A short myotomy improves technical success; however, outcomes have not previously been evaluated.

Methods: This was a multicenter, international, retrospective study of patients who underwent POEM with short (≤4 cm) or standard esophageal myotomy.

Evaluating no fixation, endoscopic suture fixation, and an over-the-scope clip for anchoring fully covered self-expanding metal stents in benign upper gastrointestinal conditions: a comparative multicenter international study (With Video).

Background And Aims: Fully covered self-expandable metal stents (FCSEMSs) are widely used in benign upper gastrointestinal (GI) conditions, but stent migration remains a limitation. An over-the-scope clip (OTSC) device (Stentfix {SF], Ovesco Endoscopy) for stent anchoring has recently been developed. The aim of this study was to evaluate the effect of OTSC fixation on FCSEMS migration rate.
