[A Case of Emergency Surgery for Intussusception Due to Cecal Cancer].

A 79-year-old woman was admitted to the hospital because of continuous right lower abdominal pain lasting for 1 day. There was tenderness with signs of peritoneal irritation at the right lower abdomen along with a palpable mass. With the diagnosis of intussusception of the ileocecal region by CT examination, an emergency surgery was performed under general anesthesia. By laparoscopic ileocecal resection with lymph node dissection, the ileocecal region was found invaginated into the transverse colon, although this was easily reduced by Hutchinson's procedure. The histological diagnosis of the tumor was highly differentiated adenocarcinoma in Stage Ⅲb. The postoperative course was uneventful and the patient remained in good health without any recurrence during a follow-up period of 12 months. When a patient has a sign of peritoneal irritation, such as in our case, and intestinal tract necrosis and perforation by intussusception cannot be excluded, it is necessary to perform an emergency surgery.
