Abstract:
Objective:To evaluate the feasibility and preventive efficacy of a fascia- locking circular continuous suture ostomy technique in reducing parastomal hernia incidence.Methods:This technique was applied to patients undergoing permanent colostomy following radical rectal cancer resection. Surgical steps included: (1) A circular incision was made 1-2 cm medial to the intersection of the lateral margin of the rectus abdominis muscle and the line connecting the umbilicus to the left anterior superior iliac spine. Subcutaneous tissues were dissected vertically to expose the anterior rectus sheath, followed by blunt separation of the rectus abdominis after longitudinal incision of the sheath. The posterior rectus sheath and peritoneum were similarly incised. (2) Eight equidistant interrupted sutures (anchoring knots) were placed through the anterior rectus sheath, partial rectus abdominis, posterior rectus sheath, and peritoneum. (3) The terminal colon was exteriorized, and continuous sutures were applied to secure the anchoring knots and seromuscular layers of the bowel between knots, forming a circular locking mechanism by tying the terminal suture to the initial knot's tail. (3) The skin and seromuscular layers of the bowel margin were intermittently sutured (8-12 stitches) to achieve mucosal eversion.Results:From February to October 2023, 13 patients (11 males, 2 females; age: 67 ± 10 years; BMI: 23.8 ± 4.0 kg/m2) underwent this technique at the Second Affiliated Hospital of Army Medical University. Mean stoma creation time was 15.7 ± 3.0 minutes. During a follow-up of 14.6 ± 3.1 months, physical examinations and abdominal CT scans identified parastomal hernias in 2 male patients at 10 and 7 months postoperatively. Only one patient experienced a Clavien-Dindo grade ≥Ⅲ complication, which resolved with treatment. No stoma-related complications (e.g., infection, stenosis, or prolapse) occurred in any patient.Conclusion:The fascia-locking circular continuous suture ostomy technique is safe and feasible, demonstrating potential efficacy in preventing parastomal hernia following colostomy.
