Abstract:
Objective To discuss CT examination in the diagnosis of gastrointestinal perforation (GP). Methods All CT data of 13 adult patients with GP were reviewed retrospectively. Results In all 13 cases,gastric perforation occurred in 5 cases,duodenal perforation in 7,and traumatic duodenal avulsion in 1.CT findings of GP included gas accumulation under the recess of xiphoid,gas accumulation in the area of lesser omentum,gas accumulation under the recess of peritoneal cavity,and seroperitoneum. Conclusion As a non-invasive examination means for abdomen,CT examination can discover whether there is dissociative gas or not and estimate the amount of gas in abdomen more rapidly and exactly.CT can also estimate the position of perforation elementarily.The recess under xiphoid is the first place where the dissociative gas assembles after gastrointestinal perforation.
