Loop ileostomy fixation: a simple technique to minimise the risk of stomal volvulus

Turnbull's “loop” ileostomies is a routinely performed procedure in the management of a variety of colorectal problems. Mechanical and functional complications occur with both permanent and temporary ileottomies, however they are more common with the loop than with the end (Brooke) variety. With the advent of restorative proctocolectomy with pouch formation, and the documented benefit of simultaneous temporary faecal diversion, the incidence of such complications will rise. Bowel obstruction, requiring laparotomy in the interval before stoma closure, is more commonly associated with the loop ileostomy. A loop stoma is routinely brought out directly through the abdominal wall, with little or no fixation or closure of the lateral space. However, anti-mesenteric fixation, as described here, minimises the risk of volvulus by widening the attachment of the adjacent ileum to the parities, creating a broader fulcrum. Since adopting this simple technique, we report no complications in over 30 loop ileostomies, “fixed” by this technique and followed up for a minimum of 4 years. Where applicable, no difficulty was encountered with stoma closure, either by a transverse single layer serosubmucosal technique, or as a minimal resection with end to end anastomosis (sewn or stapled), following bowel mobilisation. This technique should minimise the frequency of obstructive events, and we recommend it's routine use.
