New technique: removal of embedded esophageal partially covered stent by endoscopic sub-stent space dissection.

Both fully (FCSEMS) and partially (PCSEMS) covered self-expandable metal stents are used for the endoscopic management of leaks, perforations, and fistulas. PCSEMS have lower migration rates as their uncovered flanges allow for anchorage into the surrounding tissue, but this consequently makes them difficult to be removed, with reported cases of esophageal perforation during the removal of the embedded PCSEMS. Stent-in-stent technique is mostly used, where a FCSEMS is placed co-axially into an existing PCSEMS causing pressure necrosis and facilitating subsequent removal of both stents. This technique, although effective, is expensive, requiring the use of a second stent. In this report, we describe a series of 3 patients with embedded PCSEMS removed by a new endoscopic technique, i.e., endoscopic sub-stent space dissection, without using a second stent.

Rescuing the Rescuer: Fractured Dormia Basket and a Second Basket Rescue Technique.

Mechanical lithotripsy is one of the well-known rescue methods for impacted common bile duct (CBD) stones. A fractured Dormia basket with a captured stone is an unusual complication and poses a special management problem. In the past, surgical intervention was the standard method. Various nonsurgical techniques have been reported. If the impaction is at the level of the papilla, extending the sphincterotomy might be sufficient. Stent insertion, endoscopic mechanical lithotripsy, extracorporeal shock wave lithotripsy, endoscopic laser lithotripsy, and transhepatic choledochoscopic lithotripsy have all been reported. In this case, we used a second basket, which is readily available and less expensive, as a rescue technique. HOW TO CITE THIS ARTICLE: Khamaysi I, Hajj E.

Drug-induced Pancreatic Atrophy ("The Vanishing Pancreas").

Immune checkpoint inhibitors have become the therapeutic mainstay in a rapidly growing number of cancers. Immune checkpoint inhibitor-related diarrhea is attributed mainly to inflammatory colitis, with no other drug-related differential diagnosis. However, other causes of diarrhea should be considered. Pancreatic atrophy (and exocrine pancreatic insufficiency) is a relatively rare complication of immune checkpoint inhibitors. Herein we bring a set of striking computed tomography (CT) images that demonstrate a drug-related-progressive pancreatic atrophy until complete vanishing of pancreatic tissue. Exocrine pancreatic insufficiency (EPI) was diagnosed. Pancreatic enzyme replacement therapy was initiated with an excellent clinical response. How to cite this article: Khamaysi I, Hajj E.
