Current Practice of Acute Appendicitis Diagnosis and Management in China (PANDA-C): A National Cross-Sectional Survey.

Abstract

Background: The aim of this study was to describe and analyze the current status of the diagnosis and management of acute appendicitis in China. Patients and Methods: An online record system was used to collect data retrospectively from 52 medical centers in mainland China. All patients with acute appendicitis who were first treated at the hospital in 2017 were included and followed up for one year. Propensity score matching (PSM) was used to exclude the potential confounders and analyze the difference in outcomes between the non-operative management (NOM) and surgical groups. Results: A total of 10,187 patients were enrolled, of whom 5,517 (54.2%) were males. A total of 2,056 (20.2%) cases received NOM. The one-year recurrence rate of appendicitis in the NOM group was 19.3%. On PSM analysis, we found that the NOM group had a lower complication rate (2% vs. 4.2%; p = 0.001) and an acceptable success rate (96.8% vs. 100%; p < 0.001) compared with the operative group in patients with non-complicated acute appendicitis. However, in the complicated acute appendicitis population, the in-hospital complication rate in the NOM group was higher (10.8% vs. 5.8%; p = 0.048) and the success rate was lower (95.4% vs. 100%; p < 0.001) than the operative group. The recurrence rate was lower in patients with non-complicated acute appendicitis than in those with complicated acute appendicitis (17.3% vs. 30.8%; p = 0.010). In the operative group, pre-operative antimicrobial prophylaxis-covered anaerobes could reduce the surgical site infection (SSI) rate compared with that in the non-covered anaerobes group in non-complicated patients (0.9% vs. 1.9%; p = 0.020). Conclusions: Appendectomy is currently the most effective treatment for acute appendicitis. However, NOM is an alternative treatment for non-complicated acute appendicitis but not for complicated acute appendicitis because of the lower complication rate, considerable success rate, and recurrence rate.
