Bioabsorbable Seamguard (BSG) is a random-fiber web of polyglycolic acid/trimethylene carbonate. It is completely absorbed within 6 months or less due to its constitution of a bioabsorbable membrane with polyester braided suture. It has been used in obesity surgery and pulmonary surgery as staple-line reinforcement with good results. As such, we believe that BSG may be ideal to use in colorectal surgery as an aid during the healing process of an anastomosis and may help prevent anastomotic bleeding and staple-line disruption. From July 2003 through September 2004, 30 patients underwent placement of BSG for the following procedures: 12 right hemicolectomies, 7 low anterior resections, 5 sigmoid colectomies, 3 total colectomies, 2 partial resections, and 1 colostomy closure. Median follow-up was 7 months (range 1-13). There were no clinical leaks, no strictures, and no bleeding in our early postoperative follow-up period. The use of BSG as a staple-line reinforcer appears to be safe and may be useful in preventing anastomotic leakage, bleeding, and intraluminal stenosis.
