Comparative study between parietal peritoneum suture and nonsuture in midline laparotomies in rats.
OBJECTIVE
Compare the parietal peritoneum suture and nonsuture in midline laparotomies in rats, as for the formation of adhesions.


METHODS
40 adult albino Wistar rats (20 males and 20 females) underwent a surgery, weighing between 350 and 400 grams. After anesthesia, a midline laparotomy was performed, followed by cavity closure with and without peritoneum suture. After 40 days, the rats underwent a new surgery in order to verify the peritoneum and check if there were any adhesions, and the rats were then sacrificed.


RESULTS
Statistical analysis showed there was no significant difference between the adhesions occurring or not with peritoneal suture or nonsuture, including in relation to the rats' gender.


CONCLUSIONS
Closing the peritoneum or not does not interfere with the formation of adhesions after midline laparotomies in rats from both genders.
