We conducted laparoscopic partial excision of the cecum to treat mucinous cystadenoma of the appendix in a 67-years old woman admitted to our hospital due to submucosal tumor in the cecum on colonoscopy. Barium enema and abdominal computed tomography (CT) showed mucocele in the appendix and laparoscopic partial excision was conducted. Ileocecal stenosis occurred temporarily postoperatively, but no serious sequel was observed. Postoperative pathologic examination showed that the mucocele was benign mucinous cystadenoma. Even though the mucocele did not appear malignant histologically, it could induce pseudomyxoma peritonei, so surgery is often chosen with appendectomy, ileocecal resection, or right hemicolectomy done after abdominal section. Although laparoscopy has recently been applied to mucocele treatment, little attempt has been made to apply laparoscopic partial excision of cecum according to our search of a computer-assisted database. As indicated here, laparoscopic partial excision of cecum for a mucocele is beneficial in diagnosis and is safe and less invasive than conventional operation.
