The Authors report on their experience in endoscopic laser photoablation (Nd-YAG laser) of advanced, non surgical rectosigmoid tumors, large sessile adenomas and their recurrence after polypectomy. 37 patients have been studied: 21 out of them had an advanced rectosigmoid tumor, 10 out a large sessile adenoma, and the remaining 6 had a recurrence of adenoma after polypectomy. All the rectosigmoid tumors improved either clinically or symptomatically after 2-4 laser treatments. In 2 cases stenosis occur after laser therapy but no dilatation was necessary. Large adenomas and recurrence were all cured by the laser treatment, with a recurrence rate of about 30% at six months. In conclusion, endoscopic laser treatment is a safe and effective technique for the treatment of benign sessile rectosigmoid tumors and for palliation of symptoms from malignant ones in selected non surgical patients.
