[Report of a Case Having Adult Intussusception Associated with an Ascending Colon Cancer].

A 66-year-old woman was referred to our hospital with complaints of pain in the lower right abdomen and bloody stools for 2 days. The WBC counts of 9,100/μL, CRP levels of 5.0 mg/dL, Hb counts of 9.8 g/dL were without normal range, but no other abnormal values were noted. Abdominal CT showed intussusception of the right colon with a solid tumor. Lower gastrointestinal endoscopy revealed a type 1 tumor in the ascending colon. The scope was not passed through to the oral side, and repositioning by endoscopy was unsuccessful. Since abdominal pain had been continued, an emergency surgery was performed. Surgical findings revealed a protruding lesion at the ascending colon that extended to the transverse colon, and the intussusception was intrusive up to the ascending colon at the end of the intestinal ileum. Thus, right hemicolectomy of the colon with D3 lymphadenectomy was performed. Resected specimens revealed a type 1 tumor measuring 60 mm in diameter at the ascending colon. Histopathologic findings revealed pT2, pN1a, cM0, pStage Ⅲa tumor. The postoperative course was favorable, and the patient was discharged on the postoperative day 13.
