Isolated adult ileocecal intussusception in sigmoid colon due to non-specific inflammation.

Adult ileocecal intussusception due to non-specific inflammation is a rare condition. Intussusception is the intestinal segment telescoping into the adjacent intestinal lumen. Typically, a pathological lesion is discovered with a high percentage of malignancy. Intussusception of the most common ileocolic kind includes the appendix, but it is uncommon for an appendix to serve as the lead point. The patient was admitted to the emergency department with a complaint of acute intestinal obstruction. After getting a diagnostic workup, an exploratory laparotomy was done, and the ileocecal and ascending colon segment was intussuscepted directly into the sigmoid colon. Transverse and descending colon were normal, and resection of necrosed intussuscepted bowel, primary repair of sigmoid colon with ileostomy with transverse colon as distal mucus fistula done, after the 3-month restoration of bowel continuity done, patient discharged and doing well. After the diagnosis of intussusception, the best surgical choice is in the hands of an experienced surgeon.
