摘要

Background

To explore the risk factors of intra-abdominal abscess (IAA) after laparoscopic appendectomy (LA).

Methods

A total of 839 patients who underwent LA in Nanjing Jiangbei Hospital from July 2021 to November 2024 were retrospectively analyzed, and their clinical data were collected. Through univariate and multivariate analysis, the risk factors affecting the formation of IAA after operation were screened, and the predictive efficacy was evaluated by ROC curve.

Results

After screening, there were 25 cases with IAA after operation, 741 cases were cured and 73 cases were excluded. Multivariate analysis showed that appendix perforation (OR = 4.763, 95%CI: 1.827 ~ 12.414, P = 0.001) and operative time (OR = 1.024, 95%CI: 1.002 ~ 1.046, P = 0.029) were related to the formation of IAA after operation. The area under ROC curve (AUC) of appendix perforation was 0.623, and the operative time was 0.683.

Conclusion

For patients with LA, perforation of appendix and longer operative time are independent risk factors for the formation of IAA after operation, which can help predict whether IAA will occur after operation.
