BACKGROUND: Personal experience on transanal excision of rectal adenomas without affecting sphincteric function is reported.
METHODS: From 1985 to 1997, 27 patients suffering from rectal adenomatous polyps underwent surgery; the sites of lesions were within 3 to 10 cm from anal orifice in the whole series; the age of patients ranged from 30 to 81 years. Two different procedures were employed: the Parks' technique and the electroresection by traction flap technique according to Faivre.
RESULTS: Any postsurgical complication such as hemorrhage, stenosis or incontinentia occurred; surgical mortality was absent. Histological examination disclosed severe dysplasia as well as in situ carcinoma in 6 patients (22.2%) and malignant polyps in 9 patients (33.3%). Only in a case a palliative excision was performed since the poor general conditions of this patient did not permit a more extended treatment; a local relapse of the tumour associated with liver metastases led the patient to death 22 months after surgery. Three patients were lost to follow-up and 2 patients died because of other causes, 6 and 8 years after surgical excision, respectively.
CONCLUSIONS: The conclusions are is drawn that either Park's and Faivre's procedures are useful and safe for the surgical treatment of rectal villous polyps extended up to 8-12 cm from anal orifice, in spite of the presence of malignant foci within their mass. These surgical procedures are simple and relatively poor traumatic; for this reason they are more suitable than other transabdominal or abdomino-perineal approaches for older patients and other at risk-patients. It is underlined that the treated patients require a long-term follow-up aimed at the early diagnosis of possible relapses of adenomatosis.
