Does the length matter in acute appendicitis for the perforation risk?: A retrospective cohort study

Abstract

It has been hypothesized that short appendices increase intraluminal pressure more rapidly and perforate more frequently than long appendices. Two hundred seventy-seven adult patients were retrospectively analyzed and underwent an appendectomy between January 2015 and August 2021. Data extracted from patient records included sex, age, time from admission to operation (hospital interval), weekday or weekend operation time, and operative and pathological findings. Operation was performed on 273 patients, of whom 178 (65.2%) were male and 95 (34.8%) female. The mean age of the male patients was 31.7 +/- 08 (range 18-67), and that of the female patients was 38.9 +/- 1.4 (range 18-78). Perforation was observed in 57 (20.9%) patients. Sex was not a factor in the development of perforation (P = .95). The mean age of the patients with and without perforation was 40.1 +/- 2.2 and 32.7 +/- 0.7, respectively. The perforation rate increased with age (P = .003). Appendix lengths were similar in both groups, and length was not a factor in the development of perforation (P = .83). This study found that the development of perforated appendicitis is not related to the length of the appendix. The risk of perforation increased with age.
