 We report a case of mucinous cystadenocarcinoma of the appendix with intussusception, which was treated by laparoscopic surgery with intracorporeal anastomosis. An 88-year-old woman presented with lower right quadrant pain. Computed tomography revealed intussusception in the ascending colon induced by a cystic tumor of the appendix root. Colonoscopy was performed under the diagnosis of intussusception by mucinous cyst of the appendix. Intussusception was easily reduced by colonoscopy and a submucosal tumor-like mass was observed in the cecum. Because of the possibility of mucinous cystadenocarcinoma of the appendix, laparoscopic ileocecal resection with intracorporeal anastomosis was performed cautiously. During intracorporeal anastomosis, the peeling operation was minimized and the procedure to lift the intestinal tract was not performed, thereby reducing the risk of cystic rupture. To prevent dissemination, the resected ascending colon and ileum including the tumor were placed in the retrieval bag and removed. The patient was discharged from our hospital 8 days after surgery. Histopathological examination confirmed a mucinous cystadenocarcinoma of the appendix (T3, N0, StageⅡ). The patient is alive without recurrence 17 months after surgery.
