Comparative study between parietal peritoneum suture and nonsuture in midline laparotomies in rats

Abstract

Purpose: 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.

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