Ileostomy rod - is it a bridge too far?

Objective Defunctioning loop ileostomies are used commonly to protect low colorectal anastomoses and thereby reducing the serious complications of leakage. However, they are associated with specific complications such as retraction. Traditionally, a supporting rod is placed as a bridge to support both limbs of the stoma in the hope of reducing the incidence of stomal retraction. There is little evidence in the published literature to support this practice. The aim of this study was to determine whether using an ileostomy rod would reduce the incidence of stomal retraction. Method A prospective, randomised controlled trial was performed in 60 consecutive patients who required a defunctioning loop ileostomy. Patients were allocated to either a 'bridge' or 'bridge-less' protocol. All the patients were assessed by dedicated stoma nurses for at least 3 months and until their stomas were closed. Their postoperative symptoms, including stoma activity and retraction rate, were recorded. Results Between May 2001 and June 2004, 57 patients completed the study (28 bridge; 29 bridge-less). There were no significant differences in the retraction rate between the groups. No clinical anastomotic leakage was recorded and none of the patients required early closure. Conclusions If a loop ileostomy is constructed properly, stomal retraction is uncommon and routine use of a bridge is unnecessary.
