Ileocolonic anastomosis: a comparison of the patency of stapled versus hand-sewn techniques.
This study compared strength of hand-sewn sutures to that of staples for end-to-end anastomoses of ileocolostomies in 20 mongrel dogs. In ten dogs, the authors used four applications of staples for the anastomoses. In the other ten, they performed single-layer anastomoses using 4-0 polypropylene sutures. Half the dogs were sacrificed on the third postoperative day; half were sacrificed on the fifth postoperative day. Bursting strengths were obtained by infusing air through a catheter inserted into the colon. Results showed the single-layer hand-sewn anastomosis was significantly stronger than the stapled anastomosis. In addition, a histologic comparison of the two closures showed no difference in inflammatory responses.
