Purpose
Our goal was to assess the outcomes of rectal wall suture during the early and late periods after transanal endoscopic microsurgery (TEM) and long-term bowel function.
Methods
Patients who underwent TEM for rectal neoplasms from May 2017 to March 2021 were prospectively included. A total of 70 patients were enrolled. Seven to 10 days after TEM, clinical data were recorded, and digital rectal examination and rigid proctoscopy were performed. After at least 6 months, bowel function was evaluated using low anterior resection syndrome (LARS) and Wexner questionnaires.
Results
Forty-five men with an average age of 67 ± 10.1 (40–85) were included. TEM sutures were recorded as intact in 48/70 (68%) and as dehiscent in 22/70 (32%). It did not have any significant clinical manifestation and was not related with longer postoperative stay or incidence of postoperative complications. Eight of 22 (36.4%) patients with suture dehiscence had per rectal bleeding or febrile temperature without any need for intervention or treatment. The only risk factor for wound dehiscence was a posteriorly located defect. In late postoperative period, there was no difference between groups in LARS or Wexner questionnaire (p value 0.72 and 0.85, respectively).
Conclusions
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.
