Role of Mesh Stoma Reinforcement Technique (MSRT) in Prevention of Parastomal Hernia After Ileal Conduit Urinary Diversion

Parastomal Hernia Clinical Trial

Official title: Role of Mesh Stoma Reinforcement Technique (MSRT) in Prevention of Parastomal Hernia After Ileal Conduit Urinary Diversion: A Randomized Controlled Trial

Status Recruiting

Clinical Trial Summary

The aim of this clinical trial is to investigate the safety and efficacy of prophylactic mesh on prevention of parastomal hernia(PSH) after ileal conduit urinary diversion (IC) in a randomized controlled fashion.

Clinical Trial Description

All patients will be recruited from the urology practice of the study`s investigators, Urology department of Urology and Nephrology Center (UNC), Mansoura university, Egypt. Patients will be asked to participate after the patient and physician have made a decision that ileal conduit urinary diversion of choice. Those patients meeting all inclusion criteria will be asked to participate in this study with informed consent then obtained. No monetary income will be offered for participation in the study.

Those patients will be evaluated clinically and radiologically according to the specified protocol.

After enrollment in the study, the stoma site will be marked on the skin the day prior to surgery by the stoma therapist. All patients will be operated by high volume surgeon experienced in IC urinary diversion. The procedure started by radical cystectomy and bilateral pelvic lymphadenectomy. After sparing the distal 15 cm of the terminal ileum, a 15 cm ileal segment will be isolated and the bowel continuity will be restored and the mesenteric defect will be closed. The distal end of the isolated bowel segment will be mobilized and exteriorized at the predetermined site on the abdominal wall followed by stoma eversion. A preferred rectal muscle splitting approach is preferred for IC exteriorization. In case of MSRT, dissection of subcutaneous fat off the rectus sheath will be accomplished to create a potential space for mesh placement. Then, 5 x 5 cm polypropylene mesh will be placed and incised at the center to create an orifice to allow IC exteriorization. The mesh is then fixed to underlying rectus sheath with 1-0 non-absorbable proline sutures. The IC is exteriorized through the central orifice and then fixed to the peritoneum and to the cut-edges of the rectus muscle using 3-0 polyglactin sutures. A 12 CH subcutaneous tube drain will be fixed and the subcutaneous tissue is closed to collapse the dissected space around the mesh. The stoma is then everted and fixed to the skin. Sham group patients will undergo the same technique without mesh placement. The ureters will be mobilized and anastomosed to the proximal end of the conduit using direct ureteroileal anastomosis.

All patients will undergo the routine protocol at the investigators' center including enrollment in fast track restoration of bowel habits, ileal conduit catheter to be removed on the 5th day and the ureteral stents on the 7th and 8th days. Any deviation from normal postoperative course will be recorded using the modified Clavien-Dindo system.

At followup, patients will be asked to attend the outpatient clinic at 1, 3, 6, and 12 months after discharge clinically and radiologically to assess the intended outcomes of the study. ;
