Abstract
There may be technical difficulties in the use of recommended clamp for the insertion of the purse-string suture during the construction of an end-to-end staple anastomosis. Hand sewing the purse string eliminates some of the problems, but unless the suture is positioned within a few millimetres of the cut edge of the bowel, ischaemic tissue may be included in the staple line. In dogs, this leads to anastomotic dehiscence. The anastomosis may, however, be protected by excising the ischaemic tissue and reinforcing the staple line with sutures. An "over and over" purse-string technique is now preferred to minimize the risk of this occurring.
