Background: Anastomotic leakage (AL) remains an important complication after colorectal surgery. Experimental research aims to find a solution to overcome this serious complication; however, no validated AL model exists in the rat. This study was designed to develop a feasible new, reproducible AL model for use in colorectal anastomotic research. Methods: Forty-four male Wistar rats, randomly divided into 4 groups, underwent a midline laparotomy and transection of the proximal colon. An anastomosis was created with 3, 4, 5, or 12 (control) sutures. After 7 days, the rats were euthanized and scored for the presence of AL. The secondary outcomes were anastomotic bursting pressure (ABP), histological evaluation, and maturation of collagen. After the initial experiment, the AL model was reproduced in an external academic center to ensure reproducibility. Results: AL occurred in 68.8% of rats treated with an insufficient anastomosis, compared to 10% of the control group (P=0.005). AL rates were highest (81.8%) in the 3-suture group and lowest (50%) when 5 sutures were used. The experiment with 4 sutures was reproduced at an external academic center and showed similar AL rates as in our center (72.7% vs. 63.6%). Conclusions: Our rat model for inducing AL by creating an anastomosis using an insufficient number of sutures is feasible and reproducible. When combining all outcome measures, the AL model for colorectal leakage using 4 sutures is the most suitable for use in future research.

Background Although cyanoacrylate glue (CA) has been widely used in various kinds of medical applications, its application in gastrointestinal anastomosis remains limited, and outcomes of experimental studies have not been satisfactory. This systematic review summarizes research regarding CA application in intestinal and colorectal anastomosis, and correlates methodological aspects to experimental outcomes. Methods A systematic literature search was performed using Medline, Embase, Cochrane, and Web-of-Science libraries. Articles were selected if CA was applied to intestinal or colorectal anastomoses. Included articles were categorized according to CA molecular structure; the method details in each study were extracted and analyzed. Results Twenty-two articles were included. More than half of the inclusions reported positive outcomes (seven articles) or neutral outcomes (eight articles). Analysis of the methods revealed that methodological details such as CA dosage, time of polymerization were not consistently reported. Porcine studies, inverted anastomosis, and n-butyl-cyanoacrylate studies showed more positive outcomes; everted anastomosis, and oversized sutures might negatively influence the outcomes. Conclusions Owing to the positive outcome from the porcine studies, application of CA in gastrointestinal (GI) anastomosis still seems promising. To achieve a better consistency, more methodological details need to be provided in future studies. Optimizing the dosage of CA, choice of animal model, inverted anastomosis construction, and other method details may improve intestinal and colorectal anastomoses with CA application in future studies.
