We present a case of intussusception due to advanced ascending–colon cancer necessitating radical laparoscopic surgery after colonoscopic repositioning. A 42–year–old woman seen for lower abdominal pain was found in abdominal ultrasonography to have a target sign of the ascending colon. Enhanced computed tomography (CT) showed multiple concentric ring signs and local colon–wall thickening diagnosed as tumor–induced intussusception. Colonoscopy indicated a polypoid ascending–colon tumor with intussusception, reduced by air injection. Histological findings showed moderately differenriated adenocarcinoma. Seven days after intussusception repositioning, laparoscopic right hemicolectomy with lymph node dissection was conducted with 4 trocars. Pathologically, the 7.5×4.0 cm tumor was moderately differentiated adenocarcinoma type 1 pSS in depth, ly1, v2, and pN0. Adult intussusception is rare and mostly tumor–induced. If intussusception is reduced by colonoscopy or enema, elective laparoscopic surgery is a possibility.
