A Case of Intussusception Due to Inverted Appendeceal Stump Produced by Appendectomy in the Adult

Abstract

Intussusception in the adult is a rare entity in the literature. This report presents a case of intussusception due to inverted stump of the appendix produced by previous appendectomy.
The patient is 38-year-old man, who was admitted to our hospital with RLQ pain. Appendectomy had been performed eight months ago. The mass, fist in size, was palpable at the right lower abdomen. Small intestinal gas was noted on the plain X-ray films of the abdomen. Intussusception of the ascending colon was confirmed by abdominal CT with a characteristic sign, so called “target like appearance”. Reduction of the intussuscepted ascending colon was successfully performed under electronic endoscopic control.
A polypoid elevated lesion was endscopically noted at the head of intussuscepted colon. It was the inverted appendeceal stump prodused by previous appendectomy. The polypoid lesion was released with removal of suture materialnoted around the inverted appendeceal stump. Abdominal CT and electronic colonoscopy are very useful for diagnosis and treatment of intussusception.
