Background
When delivering bowel through the abdominal wall for loop stoma formation, the bowel can be traumatised by the use of instruments and digital traction. This technique allows for atraumatic bowel delivery.
Technique
This technique can be used to create any loop stoma, both open and laparoscopic. The example used is a laparoscopic loop ileostomy.
The desired loop for stoma formation is identified and the orientation confirmed. A mesenteric window, close to the edge of the bowel and avoiding vessels is created using blunt dissection with a Maryland (Fig 1). A 30-cm length of nylon tape is introduced; one end is grasped with the Maryland (Fig 2) and withdrawn through the mesentery, resulting in one end of tape either side. The two ends are grasped with a ratcheted instrument to create a sling at the point to be delivered (Fig 3).

The stoma hole is made through the abdominal wall. The grasper is identified and the two ends of tape delivered with gentle traction allowing for atraumatic bowel delivery. The orientation of the bowel is confirmed and the stoma formed in the usual fashion.
Discussion
Loop stoma formation is a common procedure in emergency and colorectal surgery. This simple technique, which, to the authors’ knowledge, has not been previously described, results in bringing the bowel loop accurately and efficiently through the abdominal wall in an atraumatic fashion. In our series, there have been no incidents of mesenteric vascular injury or bleeding. The technique requires minimal expenditure and is easily reproducible.
