IS THE LOCALIZATION OF THE TUMOR IN INTRA-PERITONEAL PART OF THE RECTUM CONTRAINDICATION TO TRANSANAL ENDOSCOPIC MICROSURGERY?

Abstract

Transanal endoscopic microsurgery (TEM) is the method used in cases of benign tumors at the early stages of rectal cancer. The tumor localization in peritonized part of the rectum indicates a limiting level for removal of the neoplasm. TEM was performed on 137 patients. The mean age was 63,8±9,8 years and the number of women consisted of 65,7%. Neoplasms were located in the upper ampullar rectum and a potential possibility of connection with the peritoneal cavity was noted in 12 (8,7%) patients, but during TEM it was only in 5 cases. There wasn’t any conversion to a peritoneal surgery. The wound closures were carried out from the side of the rectum lumen and all the operations were finished with the control laparoscopy and formation of sigmostoma. The stomas were closed in 3 patients on fifth- sixth weeks. A connection with the peritoneal cavity during TEM isn’t critical event in the case of wound closure through surgical rectoscope and it doesn’t lead to the conversion to radical operation.
