Background: Previous experimental studies on cyanoacrylate (CA) glue for the prevention of colorectal anastomotic leakage (AL) have shown promising results. The aim of this study was to investigate the effect of CA in prevention of leakage in a porcine model of ischemic colorectal AL. Methods: Twenty-four animals were divided into four groups of six: (1)ischemic anastomosis with sufficient suture (ISCH), (2)ischemic anastomosis with sufficient suture and CA reinforcement (CA-ISCH), (3)ischemic anastomosis with insufficient suture (ISCH-AI), and (4)ischemic anastomosis with insufficient suture and CA reinforcement (CA-ISCH-AI). In CA groups, N-butyl-2-cyanoacrylate was applied between the colon ends. Anastomotic bursting pressure, abscess formation, and adhesion formation were evaluated on postoperative day 7. Tissue samples were obtained for histologic evaluation of foreign body reaction. Results: The AL rate was 4 of 6 (67%) in the ISCH-AI group compared with none in the other three groups. The ISCH and ISCH-AI groups had significantly higher AL scores compared with the CA groups. The mean anastomotic bursting pressure was 167 ± 54 mm Hg in the ISCH-group versus 213 ± 43 mm Hg in the CA-ISCH-group (P = nonsignificant) and 145 ± 102 mm Hg in the ISCH-AI group versus 187 ± 19 mm Hg in the CA-ISCH-AI group (P = nonsignificant). The average adhesion score was significantly higher in the ISCH group than in the CA-ISCH group (4.2 ± 1.3 versus 1.7 ± 0.82; P = 0.019). Stricture of the anastomosis occurred only in the non-CA groups (3/12, 25%). Conclusions: Anastomotic reinforcement with CA is effective and safe to prevent leakage in a high-risk colorectal anastomosis in a porcine model.
