Successful endoscopic reduction of rare post-ESD colonic intussusception: A case report.

Colonic intussusception after endoscopic submucosal dissection (ESD) is an uncommon, yet clinically significant complication. Therapeutic approaches for postoperative intussusception encompass conservative management, endoscopic reduction, and surgical intervention. We present a case involving a woman in her early 40s who experienced acute abdominal pain and fever shortly after ESD for a large ascending colonic adenoma. Contrast-enhanced computed tomography (CECT) of the abdomen confirmed intussusception without bowel ischemia. Immediate colonoscopic reduction was successfully performed, followed by conservative management. The patient achieved complete recovery with no recurrence at 3-month follow up. This case suggests that in patients developing post-ESD intussusception with no evidence of bowel necrosis or perforation, primary endoscopic intervention may be attempted and can be associated with favorable outcomes, potentially reducing the need for surgical management.
