Loop ileostomy

Loop ileostomy

A loop ileostomy is often used for defunctioning a low rectal anastomosis or an ileal pouch. A knuckle of ileum is exterior - ised through a skin trephine in the right iliac fossa. An incision is made in the distal part of the knuckle, and this is then pulled over the top of the more proximal part to create a spout on the proximal side of the loop with a flush distal side still in continuity . This allows near perfect defunctioning , but also the possibility of restoration of continuity , by taking down the - spout and reanastomosing the partially divided ileum. The advantage of a loop ileostomy over a loop colostomy is the ease with which the bowel can be brought to the surface. Care is needed when the ileostomy is closed such that suture line obstruction does not occur. Closure of a loop ileostomy can be a technically challenging pr ocedure, particularly if there are dense adhesions resulting from previous surgery . -
