Intussusception is defined by Treves in 1899 as invagination of segment of bowel into adjacent segment usually proximal into distal. It’s a common cause of abdominal emergencies especially in children two years of age and younger. It accounts for 1 in 2000 infants and children and results in intestinal obstruction. Post-operative intussusception is one of the rare etiologies of intestinal obstruction that represents 0.01 to 0.25% after laparotomies and 5 -10% of all early postoperative intestinal obstructions. Our case is a ten years old female presented to the National Center for Pediatric Surgery; Gezira state; Sudan; February 2021 complaining of abdominal distention and constipation for 6 days. She had past history of acute appendicitis due to which she underwent emergency opened appendectomy. Her condition started one day after appendectomy. O/E : patient looks ill, febrile, not pale or jaundice; PR:140b/m; RR:25c/m; abdominal examination show: distended abdomen with full flanks, unhealed lanz incision with small amount of pus discharge; no dilated veins or visible peristalsis; hernia orifice were intact; lower abdomen was tense & tender; no palpable mass; DRE: rectum contains impacted hard stool. Emergency explorative laparotomy was done. Findings: Ileocecal intussusception, bowel was healthy and viable. Simple reduction was done. Conclusion and Recommendations: Post-operative intussusception usually associated with bowel ischemia and necrosis which is not consistent with our case. We highly recommended abdominal ultrasonography, CT scan; when there is a high index of suspicion.
