Intracolonic by-pass: a new technique to prevent anastomotic complications in colon and rectal surgery.

A new technique, the "intracolonic bypass" designed to prevent anastomotic complications after colonic and rectal resections is reported. It consists of a latex tube fixed to the intestinal wall above the anastomosis, which prevents the fecal stream from reaching the anastomotic site. The tube is retained until complete healing of the anastomosis and then excreted spontaneously through the anus. This new and simple technique avoids the disadvantages of a temporary diverting ileostomy or colostomy.
