A Case of Appendiceal Adenoma Diagnsed Preopertively and Resected with Laparoscopic Surgery

Abstract

A 61-year-old man had undergone colonoscopic examination regularly as follow-up after resection of a colon polyp. Colonoscopy revealed a tumor exposing the appendix orifice. Histological findings of a biopsy from the tumor demonstrated tubular adenoma and a laparoscopic appendectomy was carried out. The resected sub-pedunculated tumor of the appendix measured 7×5 mm and the histologically confirmed diagnosis was tubular adenoma. The postoperative course was favorable and he was discharged on postoperative day 7. A case of benign adenoma of the appendix diagnosed preoperatively is rare and a good indication for laparoscopic surgery.
