Bowel leaks are a dreaded complication in bariatric (gastric bypas) surgery. The most technically difficult leaking suture line to repair is on the posterior stomach, close to the gastric staple line.
The repair is usually done by using reinforcing sutures between the jejunal limb and excluded stomach, rather than resecting the entire anastomosis and redoing it. Some surgeons buttress the repair by placing a pedicle of omentum around the repair.
