Randomized clinical trial of intracutaneously versus transcutaneously sutured ileostomy to prevent stoma-related complications (ISI trial)

Background

Ileostomy construction is a common procedure but can be associated with morbidity. The stoma is commonly secured to the skin using transcutaneous sutures. It is hypothesized that intracutaneous sutures result in a tighter adherence of the peristomal skin to the stoma plate to prevent faecal leakage. The study aimed to compare the effect of intracutaneous versus transcutaneous suturing of ileostomies on faecal leakage and quality of life.

Methods

This randomized trial was undertaken in 11 hospitals in the Netherlands. Patients scheduled to receive an ileostomy for any reason were randomized to intracutaneous or transcutaneous suturing (IC and TC groups respectively). The primary outcome was faecal leakage. Secondary outcomes were stoma-related quality of life and costs of stoma-related materials and reinterventions.

Results

Between April 2011 and February 2016, 339 patients were randomized to the IC (170) or TC (169) group. Leakage rates were higher in the IC than in the TC group (52·4 versus 41·4 per cent respectively; risk difference 11·0 (95 per cent c.i. 0·3 to 21·2) per cent). Skin irritation rates were high (78·2 versus 72·2 per cent), but did not differ significantly between the groups (risk difference 6·1 (95 per cent c.i. –3·2 to 15·10) per cent). There were no significant differences in quality of life or costs between the groups.

Conclusion

Intracutaneous suturing of an ileostomy is associated with more peristomal leakage than transcutaneous suturing. Overall stoma-related complications did not differ between the two techniques. Registration number: NTR2369 ( http://www.trialregister.nl).
