title: [Bursting pressure comparison between stapler and staple line reinforcement with sutures and butress biologic material: an experimental study].
abstract: BACKGROUND
  Staple line leaks carry significant morbidity and mortality. Reinforcement is controversial. Several staple techniques have been described for this purpose. Oversuture and butressing material are more common.
  
  
  OBJECTIVE
  To compare these two ways of reinforcement and staple line without any reinforcement regarding the bursting pressure.
  
  
  METHODS
  Ten segments of small bowel were created in a pig under general anesthesia. The bowel was inflatted until burst point and the pressure was measured.
  
  
  RESULTS
  The staple line bursting pressure was 94 mmHg +/- 18,52mmHg in the stapler technique; 87,5 mmHg +/- 18,59mmHg in the oversuture and 83,33 mmHg +/- 23,04mmHg with Surgisis®. There was no statistic difference among the techniques.
  
  
  CONCLUSIONS
  Oversuture or Surgisis® use did not increase the staple line resistance in pig.
