[Results of endoscopic interventions in large and giant epithelial neoplasms of the large intestine].

The paper presents the analysis of the results obtained for 319 patients at endoscopic interventions for large and giant tumors of the colon. Altogether 415 neoplasms were removed: 207 nodular, 126 creeping and 82 flat. The latter two were removed using specially developed technique of endoscopic electroresection of the intestinal mucosa along with the tumor. Malignancy was established in 16.1% of the cases. During the endoscopic procedure 2 patients were diagnosed to have colon perforations, 24 intensive hemorrhage which was stopped endoscopically in 22 cases. One patient developed subsequently necrosis of the intestinal wall. Surgical treatment was performed in 5 patients: for hemorrhage, colon wall perforation, malignancy in 2, 2 and 1 patient, respectively. One-eight-year follow-up of 316 patients reports cure in 217 (68.6%), relapses in 79 patients (71 of them were endoscopically successfully retreated), cancer in 15 and corrosive strictures in 5 patients.
