Endoscopic lithotripsy of a gallstone impacted in lumen-apposing metal stent positioned for cholecysto-gastrostomy

Post written by Mauro Manno, MD, from the Gastroenterology and Digestive Endoscopy Unit, Azienda USL Modena, Carpi, Italy. EUS-guided gallbladder drainage with a lumen-apposing metal stent (LAMS) is a viable treatment option for acute cholecystitis and an alternative to cholecystectomy in patients at high risk for surgery. However, recurrent acute cholecystitis with stone impaction in the LAMS can …

Double-balloon enteroscopy with EUS-guided rendezvous for failed cannulation in patients with history of Roux-en-Y gastric bypass

Post written by Kambiz S. Kadkhodayan, MD, from the Center for Interventional Endoscopy, AdventHealth, Orlando, Florida, USA. We describe 2 patients with Roux-en-Y gastric bypass (RYGB) who underwent double-balloon enteroscopy—assisted ERCP (DBE-ERCP) for the management of pancreatolithiasis and choledocholithiasis. After reaching the ampulla, deep cannulation of the bile duct could not be achieved using the enteroscope. …

Circumferential endoscopic submucosal dissection of distal rectal polyp in a patient with portal hypertension complicated by bowel obstruction

Post written by Siddharth B. Javia, MD, from Confluence Health, Wenatchee, Washington, USA. Our video demonstrates a technique for circumferential endoscopic submucosal dissection (ESD) without using any traction accessories. This was performed in a patient who had significant scarring from Crohn’s colitis and portal hypertension with large blood vessels in the submucosa, which made ESD challenging. …

Long per-rectal endoscopic myotomy for a case of Hirchsprung’s disease

Post written by Akshay Kulkarni, DM, from Midas Multi-Specialty Hospital, Nagpur, India. This video case shows the procedure of per-rectal endoscopic myotomy (PREM) for a case of Hirchsprung’s disease. It was a particularly difficult case requiring a long (25 cm) myotomy, and a delayed perforation complicated recovery. However, it was successfully managed endoscopically, and the patient …

Full-thickness resection closure using reopenable-clip over-the-line method inside a submucosal pocket

Post written by Tatsuma Nomura, MD, from Mie Prefectural Shima Hospital, Shima, Mie, Japan. We recently developed a new procedure known as full-thickness resection closure using a reopenable-clip over-the-line method inside a submucosal pocket (ROLM-SP) procedure. During this procedure, the first mucosal incision was made at 20 mm from the center, and a calibrated, small-caliber tip, …

EUS-guided choledochoantrostomy as an alternative for biliary decompression in malignant distal biliary obstruction with duodenal invasion

Post written by Ahmed Altonbary, MD, FRCP, from Mansoura Specialized Medical Hospital, Mansoura University, Mansoura, Egypt. We describe a case of unresectable pancreatic cancer with extrahepatic biliary obstruction and duodenal invasion that was successfully treated with a variant of EUS-guided biliary drainage by performing EUS-guided choledochoantrostomy (EUS-CAS). EUS-guided choledochoduodenostomy (EUS-CDS) is commonly performed for biliary decompression …
