Feasibility of umbilical loop ileostomy in overweight and obese patients with rectal cancer during laparoscopic surgery: Preliminary results.

We examined the feasibility of umbilical diverting ileostomy for overweight and obese patients with rectal cancer undergoing laparoscopic surgery. Four patients who were overweight or obese (BMI > 27 kg/m ) were initially scheduled for the creation of a conventional loop ileostomy. Intraoperatively, however, this was considered too complicated because of thick subcutaneous fat, bulky mesentery, or both. Instead, patients received a diverting ileostomy with the placement of an umbilical stoma. All patients had protruding umbilical ileostomies. No severe stoma-related complications were encountered. One patient had minor skin dehiscence, and another had paralytic ileus but resumed oral intake after a short time. Performing a temporary loop ileostomy at the umbilicus was safe and feasible in this small group of overweight and obese patients. This stoma placement may avoid the problems inherent to conventional loop ileostomy in obese subjects.
