Postoperative Outcomes of Closed Versus Nonclosed Mesentery Laparoscopic Colectomy: A Retrospective Single-center Study

Abstract

Purpose: This study aimed to clarify the clinical significance of closing the mesenteric defect in laparoscopic colectomy.

Materials and methods: We retrospectively evaluated 369 patients who underwent left-sided or right-sided resection via laparoscopic colectomy at our institute. Patients were stratified by open versus closed handling of the mesenteric defect. The perioperative clinical factors, surgical maneuvers, and postoperative complications were statistically analyzed.

Results: No significant intergroup differences were found in the perioperative clinical factors or surgical maneuvers except for number of days to the first soft diet (P=0.0214) and postoperative complications (P=0.0379). Among the postoperative complications, only ileus occurred more frequently in the closed group than in the open group (P=0.0227).

Conclusions: This study revealed that closure of the mesenteric defect following laparoscopic colectomy might be associated with an increased incidence of postoperative ileus.
