PurposeThe purpose of this current study was to explore whether one-stitch method (OM) of temporary ileostomy influenced the surgical outcomes after laparoscopic low anterior resection (LLAR).MethodsWe retrospectively identified rectal cancer (RC) patients who underwent LLAR plus temporary ileostomy in a single teaching hospital from Jan 2011 to June 2023. According to the different methods of ileostomy, the patients were divided into the OM group and the traditional method (TM) group. A propensity score matching (PSM) analysis was performed to eliminate bias and compare the surgical outcomes.ResultsA total of 469 RC patients were included in this study. There were 57 patients in the OM group and 412 patients in the TM group. After 1:1 PSM, there were 57 patients in each group, and no significant difference was found in baseline information (P > 0.05). In terms of surgical outcomes of primary RC surgery, we found that patients in the OM group had shorter operation time (P < 0.01), less blood loss (P < 0.01), and shorter postoperative hospital stay (P < 0.01) than in the TM group after PSM. Moreover, there was no significant difference in both overall complications and stoma-related complications. As for the outcomes of stoma reversal surgery, patients in the OM group had shorter postoperative hospital stay (P = 0.002) than in the TM group before PSM. However, no significant difference was found after PSM (P > 0.05).ConclusionThe OM of temporary ileostomy was easier, more effective and time-saving than the TM, which did not increase the incidence of both postoperative complications and stoma-related complications.
