Reopening of the gastroduodenal pylorus after its closure in rats.

Background: Duodenal injury occurs in 3% to 12% of patients with abdominal trauma. The best procedure to treat major duodenal ruptures continues to be a challenge. The purpose of the present study was to analyze differences between the time of gastroduodenal pylorus reopening after its closure with different suture materials and to verify the influence of vagotomy on local tissue changes.
