Diagnostic yield and therapeutic impact of novel motorized spiral enteroscopy in small-bowel disorders

Post written by Mohan Ramchandani, MD, DM, from the Department of Gastroenterology, Asian Institute of Gastroenterology Hospitals, Hyderabad, India. The small bowel is long mobile organ in the peritoneum, which makes it difficult to be evaluated by conventional endoscopy. Deep enteroscopy (DE) is a cumbersome procedure; there are many shortcomings of balloon-assisted enteroscopy (BAE), which …

Postpolypectomy bleeding of colorectal polyps in patients with continuous warfarin and short-term interruption of direct oral anticoagulants

Post written by Hideaki Harada, MD, from the Department of Gastroenterology, New Tokyo Hospital, Chiba, Japan. Our study aimed to clarify the risk of postpolypectomy bleeding (PPB) after endoscopic snare resection of colorectal polyps in patients receiving continuous warfarin and 1-day cessation of direct oral anticoagulants (O-DOACs) because the evidence for use of continuous anticoagulants …

EUS-guided gallbladder drainage versus laparoscopic cholecystectomy for acute cholecystitis

Post written by Anthony Yuen Bun Teoh, FRCSEd (Gen), from the Department of Surgery, Prince of Wales Hospital, Chinese University of Hong Kong, Shatin, Hong Kong SAR. EUS-guided gallbladder drainage (EUS-GBD) is a safe alternative to percutaneous cholecystostomy (PT-GBD) for acute cholecystitis. How the procedure compares to laparoscopic cholecystectomy (LC) is uncertain. The aim of …

Evaluation of colorectal endoscopic submucosal dissection using a multifunctional snare

Post written by Jun Arimoto, MD, PhD, from the Department of Gastroenterology, Omori Red Cross Hospital, Tokyo, Japan. In this study, we evaluate the safety and efficacy of colorectal ESD using the SOUTEN snare. Although the SOUTEN snare was introduced for hybrid ESD, hybrid ESD involves partial submucosal dissection. So, we thought that “SOUTEN-ESD,” mean …

Clinical utility of cricopharyngeal distensibility measurements during endoscopic myotomy for Zenker’s diverticulum

Post written by Linda Yun Zhang, MBBS, FRACP, from the Department of Gastroenterology & Hepatology, St George Hospital, Sydney, New South Wales, Australia. Flexible endoscopic cricopharyngeal myotomy allows minimally invasive treatment of patients with Zenker’s diverticulum. Despite its wide uptake there is a substantial retreatment rate, which is at least partly due to the lack …
