Polypropylene suture in esophageal and gastrointestinal operations.

A comparison was made of the gross and microscopic wound healing and tissue reactivity between stainless steel wire, polypropylene and silk in anastomoses in the u-prepared colon of the dog. While all anastomoses healed irrespective of the suture material used, wire was associated with the least inflammatory response, silk the most and polypropylene intermediate, its low reactivity approaching that of wire. A clinical trial of Prolene for 71 varied anastomoses between pharynx, esophagus, stomach and colon in 47 patients undergoing esophageal resection and reconstruction or bypass was done. In four of the seven anastomotic disruptions which occurred, causative factors unrelated to the suture material could factorily in the remainder of these patients. Monotive suture which works well in esophageal and gastrointestinal anastomoses.
