Bioabsorbable staple-line reinforcement to reduce staple-line bleeding in the transection of mesenteric vessels during laparoscopic colorectal resection: a pilot study.
BACKGROUND: Staple line hemorrhage and leak are the 2 most dreaded complications of laparoscopyassisted resection of colorectal cancer (LARCC). Recently, anastomotic staple lines have been reinforced with a range of absorbable and non-absorbable bioprosthetic reinforcement materials. This pilot prospective study used the bioabsorbable Seamguard (BSG; WL Gore & Associates, Flagstaff, AZ) for routine reinforcement of the mesenteric vascular staple transection to prevent mesenteric hemorrhage and to assess its safety and feasibility in a consecutive series of laparoscopic colonic resections. METHODS: Twenty-five patients consecutively scheduled to undergo LARCC were enrolled in the study. All operations were performed with a standard LARCC technique which included loading of the BSG sleeves onto the jaws of the cutter/stapler. RESULTS: There were 23 wholly LARCC cases and 2 open conversions. BSG was used in all 25 patients. No patient experienced staple-line bleeding or other complications during the surgical procedure. The mean number of staple-line reinforcement sleeves used was 2.6 (range, 2-4). The mean operative time was 118 minutes (range, 65-184 minutes). Additional measures to achieve hemostasis were not required in any case. The mean cost was US 475.20 dollars for the procedure. CONCLUSIONS: This small pilot study has shown the routine use of BSG mesenteric staple line reinforcement to be safe, quick and effective during LARCC.
