  • Look Inside

 Twenty-four large adenomas of the colorectum, over 3 cm in diameter, were collected from the endoscopy and surgery files of The First Dept. of Surgery, The University of Tokyo, and their clinicopathological details and treatment modalitities were reviewed. Among 24 lesions, 11(46%) were located in the rectum, 6 (25%) in the sigmoid colon and 5 (22%) in the right colon, respectively. Gross appearances were divided into villous tumor in 12 lesions (50%), nodule-aggregating lesion in 6 lesions (25%)and polypoid lesion (Is, Isp, Ip) in 6 lesions (25%), respectively. Histology showed tubular adenoma in 8 lesions (33%), tubulo-villous adenoma in 13 lesions (54%) and villo-tubular adenoma in 3 lesions (13%), respectively. Grades of atypia were classified into Ca in adenoma in 14 lesions (58%), moderate atypia in 7 lesions (29%)and mild atypid in 2 lesions (8%), respectively. All polypoid lesions were able to be resected with endoscopic polypectomy alone and no tumor recurrence was found. However, surgical treatment (local excision or bowel resection) was mandatory for most of the villous tumors and nodule-aggregating lesions. Six of 13 tumors (villous tumor or nodule-aggregating tumor) recurred between two month and 10 years after initial treatment. All recurrent tumors were histologically benign and could be treated with endoscopic polypectomy or local excision. Re-recurrence was observed in two villous tumors, however, endoscopic polypectomy was appropriate to treat these tumors. The importance of endoscopic surveillance was stressed.
