Abstract

Introduction

Appendicitis is the surgical disease with the highest prevalence in emergency rooms. Its clinical and/or surgical complications are associated with the time course of symptoms, age, comorbidities, and stages of the disease.

Objectives

To analyze the demographic and clinical data of patients who underwent appendectomy for acute appendicitis in a tertiary referral hospital in the city of São Paulo and compare these data between services provided by the Public and Supplementary Health System.

Methodology

Retrospective analysis of data from electronic medical records of patients over 14 years old who underwent appendectomy for acute appendicitis at Hospital Santa Marcelina, both in the Public and Supplementary Health Systems from January 2015 to December 2017.

Results

A total of 536 patients were analyzed, 354 (66%) of whom were male with a general mean age of 29.85 years (14-81 years). The mean time from symptoms to seeking medical care was 53.84 hours. Regarding the phases of acute appendicitis, a greater number of cases of complicated disease was observed in patients operated on in the Public Health System (p < 0.0001), as well as the time course of symptoms (p = 0.0005) and

Conclusion

There was a predominance of male patients undergoing appendectomy for acute appendicitis, with longer time course of symptoms in those operated on in the Public Health System and a predominance of appendicitis in advanced stages (3 and 4) in this group. However, in this group there was no significant increase in the rate of postoperative infection, and the length of stay was shorter than that of patients operated on in the Supplementary Health System.
