B-suture Ileostomy in Clinical Practice: a Retrospective, Single-center, Propensity Score-matched Study

OBJECTIVE: The purpose of this study was to introduce a new temporary ileostomy modality, the B-suture ileostomy, and to compare its technical advantages in comparison with conventional ileostomy.

METHODS: A retrospective single-center study analyzed 185 patients undergoing laparoscopic low anterior resection for rectal cancer combined with temporary ileostomy, collecting general case data, surgery-related data, postoperative-related complications, secondary surgical return data, and postoperative health status data, and divided into a B-suture ileostomy group (n=62) and a conventional method ileostomy group (n=123) according to the different stoma methods, by propensity score matching (pSM) for 1:1 matching (n=59 for both groups after matching). The advantages and disadvantages of the B-suture method ileostomy were evaluated by analyzing and comparing information on the perioperative period, postoperative related complications, and postoperative health status.

Inclusion criteria

• If necessary, combine bulleted, numbered, and lettered lists in order to create lists within a list. For example:simultaneous laparoscopic low anterior resection of rectal cancer + temporary ileostomy;
• pathologically confirmed primary rectal cancer;
• rectal tumor height ≤12 cm from the anal verge;
• no tumor metastasis at the time of surgical resection;
• all surgeries were performed by the same surgical team with more than 10 years of experience in laparoscopic radical resection of rectal cancer and ileostomy.

Exclusion criteria

• patients who did not undergo stoma rejection due to tumor metastasis or recurrence;
• patients who were too old or in poor general condition to undergo stoma reversal surgery;
• patients with multiple primary colorectal cancers who underwent simultaneous multifocal resection;
• patients with incomplete clinical medical information.
