Development and validation of a nomogram for predicting perforation in the early 24 h of acute appendicitis.

ABSTRACT:

Objectives

This study aimed to develop and validate a nomogram prediction model for identifying the risk of early perforation (within 24 h) in patients with acute appendicitis, using objective clinical and imaging indicators.

Methods

A retrospective study was performed on 880 patients with acute appendicitis who underwent laparoscopic appendectomy within 24 h of symptom onset at the General Surgery Department of the Central Theater Command General Hospital between January 2011 and December 2022. Patients admitted from 2011 to 2020 were assigned to the modeling group (n = 616), and those from 2021 to 2022 to the validation group (n = 264). Based on postoperative pathology, patients were classified as having early or non-early perforated appendicitis. Independent
