Peritoneal perforation is less a complication than an expected event during transanal endoscopic microsurgery. experience from 194 consecutive cases

The aim of the present study was to investigate the occurrence, management and outcome of PP in patients having TEM. Methods: All the patients who had TEM for rectal adenoma or adenocarcinoma in our unit were included. Patients in whom PP occurred (Group A) were compared to those without PP (Group B).
