Abstract

A 58-year-old man was admitted to the hospital because of abdominal pain. A tumor was palpated in the upper abdomen. Abdominal plain X-ray film showed niveau. A barium enema study showed a crab-finger finding in the ascending colon leading to the diagnosis of intussusception. A hemispherical protrusion still remained after reduction of the intussusception. Colonoscopy also revealed submucosal tumor in the cecum. Abdominal CT scan and ultrasound showed a cystic tumor. The patient was diagnosed as having appendiceal mucocele associated with intussusception. On laparoscopy, appendiceal mucocele was found loosely attached to the retroperitoneum and invaginating into the cecum. Laparos-copy-assisted cecectomy was performed. The appendix, 12cm×3cm×3cm in size, was swollen and filled with mucin. Pathological diagnosis was mucinous cystadenoma of the appendix.<br> Laparoscopic procedure is very useful to the treatment of the appendiceal mucocele complicated with intussusception, in respects of the curability and less invasiveness.
