Surgical method for using an intraintestinal bypass graft
First Claim
1. A method of anastomosing the severed proximal and distal segments of an internal body duct of a mammal and protecting the site of the completed anastomosis, comprising the steps of:
- (a) providing a bypass graft having distal and proximal ends and comprising a tube formed of a thin, water-impervious wall material having sufficient flexibility to conform to the natural body duct movements;
(b) anastomosing the proximal end of the bypass graft to the inner wall of the proximal body duct segment at a location spaced from the distal extremity of said proximal duct segment;
(c) inserting the main body of the bypass graft into the distal body duct segment; and
(d) completing the anastomosis of the proximal body duct segment to the distal body duct segment to form the completed anastomosis site.

Abstract
A technique whereby leakage from an anastomosis and problems directly resulting from such leakage are eliminated. The technique is an anastomosis procedure for securing intraintestinal bypass graft formed preferably of a soft latex or silastic tube with a radiopaque axial line for x-ray observation after implantation. The ends of the tube are sutured or stapled to the mucosal or submucosal linings, and after a period of about 10 to 15 days during which the anastomosis is healing, the bypass graft separates naturally from the wall of the intestine, and is finally expelled naturally from the anus. This graft prevents leakage at the anastomosis and thus substitutes for and makes unnecessary a colostomy or any other diversionary procedure.
