Intussusception due to an Inverted Meckel's Diverticulum Diagnosed by Double-Balloon Enteroscopy.
An 18-year-old man presented after undergoing multiple investigations for abdominal pain. Retrograde double-balloon enteroscopy showed a protruding red lesion in the ileum with small ulcers, approximately 75 cm proximal to the ileocecal valve, resulting in an intussusception. An inverted Meckel's diverticulum was strongly suspected. Pressure was applied to the protruding lesion using contrast medium injection after wedging the lumen with a balloon. The intussusception partially reduced, avoiding the need for emergent surgery. Endoscopic tattooing was performed to mark the lesion for subsequent resection. Elective laparoscopy-assisted surgery with minimum laparotomy revealed an inverted Meckel's diverticulum, which was resected.
