Meckel's Diverticulum Causing Sigmoid Knotting and Closed‐Loop Obstruction: A Rare Case Report From a Resource‐Limited Setting

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Meckel's diverticulum rarely causes large bowel obstruction through a fibrous band, leading to sigmoid knotting and closed‐loop gangrene. In patients presenting with acute intestinal obstruction without prior abdominal surgery, this etiology should be considered.

“Cat scratch colon” causing cecal perforation as a rare complication due to barotrauma during colonoscopy: A case report and literature review

DEN Open, Volume 6, Issue 1, April 2026.
Abstract “Cat scratch colon” (CSC), characterized by spontaneous bright‐red linear markings or mucosal laceration with bleeding due to air insufflation barotrauma, is a rare complication during colonoscopy. These mucosal lacerations can present as superficial tears that do not generally have clinical repercussions or as deeper tears that damage the ...

Optimal timing of precut sphincterotomy to prevent post‐endoscopic retrograde cholangiopancreatography pancreatitis in difficult biliary cannulation: A retrospective study

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Objectives Precut sphincterotomy is often performed when bile duct cannulation is difficult; however, the former has a higher risk of complications than conventional methods. Early precut reduces the risk of post‐endoscopic retrograde cholangiopancreatography pancreatitis (PEP).

Gel‐immersion Endoscopic Submucosal Dissection for Superficial Colorectal Neoplasms: A Retrospective Study Comparing Conventional Endoscopic Submucosal Dissection

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Gel‐immersion endoscopy offers benefits such as buoyancy, traction, and a clear visual field without gas insufflation. While some case reports have described colorectal gel‐immersion endoscopic submucosal dissection (Gi‐ESD), there have been no consecutive case series. This study aimed to clarify the usefulness of Gi‐ESD.
