Summary

This study is a prospective, randomized controlled trial designed to compare two surgical techniques for stoma creation in patients undergoing colorectal surgery. The trial evaluates whether an extraperitoneal stoma created via the arcuate line approach can reduce the risk of developing parastomal hernia compared to the conventional transperitoneal stoma formation. Parastomal hernia is a common complication after stoma surgery, often requiring additional treatment or surgery. By testing a novel surgical route that avoids entering the abdominal cavity, this study aims to improve postoperative outcomes and quality of life for patients requiring a permanent stoma.

Conditions

  • Parastomal Hernia
  • Rectal Surgery
  • Stoma Complications
  • Extraperitoneal Stoma
  • Surgical Technique Comparison

Interventions

PROCEDURE

extraperitoneal colostomy

Patients in this group will undergo extraperitoneal stoma creation using the arcuate line approach. This technique involves creating a stoma through the extraperitoneal space by accessing the posterior sheath at or below the arcuate line, thereby avoiding direct peritoneal entry. The goal is to reduce the risk of parastomal hernia by maintaining abdominal wall integrity and preventing intra-abdominal content herniation around the stoma.

PROCEDURE

transperitoneal colostomy

Patients in this group will receive a conventional transperitoneal stoma. In this approach, the stoma is brought out through the abdominal wall via a peritoneal opening, which is the standard method used in colorectal surgery. This technique serves as the control for evaluating whether the arcuate line approach offers improved outcomes, particularly in reducing parastomal hernia incidence.
