Background:
The aim of our study is to select patients with nonperforated appendicitis verified by computed tomography (CT) scan and to determine if there is a temporal component to perforation.
Methods:
A retrospective cohort study of patients with CT scan evidence of nonperforated appendicitis from 2007 to 2012.
Results:
411 patients, aged 39.7 ± 16.25 years (47.5% male) were included in the study. 330 patients (80.3%) were nonperforated at surgery. Analysis of 3-hour intervals from CT scan to operating room (OR) revealed an absolute reduction in the rate of perforation from 27% at the 6- to 9-hour interval, to 17% and 10% at the 3- to 6-hour and 0- to 3-hour intervals, respectively, (P < .04). All organ space infections occurred in patients who were delayed to the OR greater than 3 hours. Mean length of hospitalization was .93 days and 2.81 days, respectively, in nonperforated and perforated appendicitis patients (P < .001).
Conclusions:
Delays to the OR were associated with increased risk of perforation. Patients with uncomplicated appendicitis had shorter hospitalization and fewer postoperative wound infections.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
