[Villous tumors of the rectum. 50 cases treated surgically].
The authors report a study of 50 patients who underwent surgery for a villous adenoma between 1978 and 1988 (29 men and 21 women). Mean age was 70 years old. 84% of the lesions were sessile. They ranged from 1 to 15 centimeters in size. They were associated 12 times with colon adenomas and 3 times with adenocarcinomas. All these lesions were biopsied preoperatively. Removal was performed: in 38% of cases vie a transanal approach in 38% of cases by colorectal resection vie an abdominal approach in 12% of cases by rectal amputation vie both an abdominal and perineal approach, in 12% of cases by Kraske's procedure. 22 adenocarcinomas and 28 benign lesions were discovered. 2 patients died in the early post-operative course after colorectal resection performed vie an abdominal approach. At long term (minimum of 2 years) there were 5 complications and 9 recurrences, the later occurring after tumorectomies. It is essential to know the lesions histologic characteristics in order to administer appropriate therapy, but this is not only possible to determine precisely before excision. Even biopsy specimens may miss the malignant portion of a lesion. Only complete pathological examination of the tumor can establish the diagnosis of a malignancy. Surgery remains the principal method of treatment of these lesions because it permits complete histologie examination and properly adapted management: simple removal for benign tumors or those with malignant degeneration in situ, wide excision for invasive tumors.
