ENDOSCOPIC REMOVAL OF LARGE NON-POLYPOUS GROWTH IN LARGE BOWEL

Abstract

The authors compare efficiency of endoscopic mucous membrane resection method and loop electrosurgical excision procedure used to remove large non-polypous and polypous growth in large bowel, and estimate results of 19 endoscopic resections and 19 loop electrosurgical excision procedures. These growths most often localized on the left half of large bowel were in the form of glandular or villous adenoma, and corresponded to surface tumors (16 cases) and wide base tumors (22 cases). The tumors were from 20 to 54 mm (30±10 mm) in size. Incomplete removal, complications and relapses were observed during both resection method and electrosurgical excision procedure. The tumor of over 22 mm in size was a factor indicating low possibility of removing en bloc. Therefore, the endoscopic mucous membrane resection method was more efficient compared to the loop electrosurgical excision in case of large non-polypous and polypous tumors of large bowel.
