Insulin-like growth factor 1-coated sutures improve anastomotic healing in an experimental model of colitis
Background: Exogenously applied insulin‐like growth factor (rhIGF‐1) may improve normal intestinal healing. This study examined the effect of rhIGF‐1‐coated sutures on anastomotic healing in experimental colitis. Methods: Acute colitis was induced in rats by dextran sodium sulphate (DSS). Inflammati...

Summary: | Background:
Exogenously applied insulin‐like growth factor (rhIGF‐1) may improve normal intestinal healing. This study examined the effect of rhIGF‐1‐coated sutures on anastomotic healing in experimental colitis.
Methods:
Acute colitis was induced in rats by dextran sodium sulphate (DSS). Inflammation was assessed by clinical Disease Activity Index (DAI), myeloperoxidase (MPO) measurement and histological examination. A distal colonic anastomosis was performed using sutures coated with rhIGF‐1 dissolved in poly(D,L‐lactide) (PDLLA) under general anaesthetic. Anastomotic healing was evaluated histologically, and by hydroxyproline measurement and bursting parameters after 1, 3 and 7 days, and compared with healthy, DSS and DSS + PDLLA controls.
Results:
DAI, MPO and histological inflammation scores were significantly increased in all animals treated with DSS. Bursting occurred less often within the anastomotic line on day 3 in the IGF group than in DSS controls (three versus eight of ten). On day 7, the IGF group had significantly increased histological healing scores (mean(s.e.m.) 12·5(0·7) versus 9·2(0·8) (P < 0·050)) and hydroxyproline content (4·6(0·3) versus 3·6(0·1) mg/g tissue; P < 0·050) compared with DSS controls.
Conclusion:
IGF‐1‐coated sutures improve important aspects of anastomotic healing in rats with experimental colitis. Copyright © 2010 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.
