title: [Effect of guided adhesions on ischemic colic anastomoses in rats].
abstract: OBJECTIVE
  Evaluate the effect of conducted adhesions on the mechanical resistance of anastomoses performed in ischemic colon through the Bursting Strength Test and Breaking Strength Test.
  
  
  METHODS
  Forty rats were divided into two groups. Group 1 was composed of 20 rats in which the anastomoses were covered with P.V.C. (Polyvinyl Chloride) to prevent the occurrence of adhesions over the anastomotic line. Group 2 was composed of 20 rats in which anastomotic line was covered with epididimal fat besides P.V.C. to prevent formation of other adhesions.
  
  
  RESULTS
  The mean Bursting Strength of the anastomoses in the group without adhesion was 10 mmHg and this value was 55.2 mmHg in the group with adhesion (p < 0.05). The mean Breaking Strength of the anastomoses was 142.5 gf in the group without adhesion and 262 gf in the group with adhesion (p < 0.05).
  
  
  CONCLUSIONS
  Based on those mechanical tests, adhesions were benefic to ischemic anastomoses, rising their intrinsic resistance both on Bursting and Breaking Strength.
