Short-term clinical and functional results of rectal wall suture defect after transanal endoscopic microsurgery-a prospective cohort study.

Our study suggests that 1/3 of the patients' rectal wall defect after TEM will undergo dehiscence in early postoperative period and will not transfer to clinically significant manifestation (without a need of hospitalization or prolonging it). In late postoperative period, there is no difference in bowel function.
