title: [Colorectal villous tumors. Treatment by electro-resection and laser photocoagulation. 134 cases].
abstract: Endoscopic snare resection prior to Nd:YAG laser photocoagulation was used to treat benign colorectal villous adenoma. One hundred and thirty four patients were included in the study: 72 with surgical contraindications, 61 for whom surgical resection appeared to be too drastic and 1 who refused surgery. Treatment sessions were repeated every fifteen days until total tumour destruction was achieved. A carcinoma was detected in biopsy specimens obtained during endoscopic treatment of seven patients. Eight patients were lost to follow up. Treatment results could be analysed in 119 patients. A successful treatment was achieved in 108 patients. Tumour destruction was complete in 85.4 percent of the cases with lesions of at least 4 cm in diameter and in 94.3 percent of the cases with smaller lesions. During the average 101 weeks follow up period, 15.7 percent of the patients with total tumour destruction had recurrence. The risk of recurrence was correlated with the number of initial treatment sessions and previous surgical treatment. It would appear that endoscopic resection prior to Nd:YAG laser photocoagulation is a safe and effective method for the destruction of colorectal villous adenomas.
