ABSTRACT
BACKGROUND:
Rectal cancer is a common cancer worldwide. Surgery for rectal cancer with low anterior resection often includes the formation of a temporary protective loop ileostomy. The temporary ostomy is later reversed in a separate operation. One complication following stoma closure is the development of a hernia at the former stoma site, and this has been reported in 7-15% of patients. The best method to avoid hernia after stoma closure is unclear. The most common closure is by suturing only, but different forms of mesh have been tried. Biological mesh has in a randomized trial halved hernia incidence after stoma reversal. Biosynthetic mesh and retromuscular mesh are currently being evaluated in ongoing studies.METHODS:
The present multicenter, double-blinded, randomized, controlled study will compare standard suture closure of the abdominal wall in loop ileostomy reversal with retromuscular synthetic mesh at the stoma site. The study has been approved by the Regional Ethical Review board in Stockholm. Patients aged 18-90 years, operated on with low anterior resection and a protective loop ileostomy for rectal cancer and planned for ileostomy reversal, will be considered for inclusion in the study. Randomization will be 11 on the operation day with concealed envelopes. The estimated sample size is intended to evaluate the superiority of the experimental arm and to detect a reduction of hernia occurrence from 12 to 3%. The operation method is blinded to the patients and in the chart and for the observer at the 30-day follow-up. The main outcome is hernia occurrence at the stoma site within 3 years postoperatively, diagnosed through CT with strain. Secondary outcomes are operation time, length of hospital stay, pain, and 30-day complications.DISCUSSION:
This double-blinded randomized controlled superiority study will compare retromuscular synthetic mesh during the closure of loop ileostomy to standard care. If this study can show a lower frequency of hernia with the use of prophylactic mesh, it may lead to new surgical guidelines during stoma closure. TRIAL REGISTRATION ClinicalTrials.gov NCT03720262.
