[Combined endoscopic treatment of villous adenoma of the stomach and large intestine in middle-aged and elderly patients].

Electroexcision combined with laser photocoagulation was performed in 12 patients with creeping neoplasms of the stomach and in 39 patients with the same condition of the large intestine. One-year follow-up studies showed that 2 patients with a malignant gastric tumour had recurrence 9 months after the combined treatment; I patient has recurrence in the same terms after similar treatment of creeping benign adenoma. Combined treatment proved to be more effective in 39 patients with large-intestinal tumour, including invasive cancer, with no recurrence during a year.
