The Incidence of Acute Peritonitis Secondary to Different Sites of Viscus Perforation.

Objective The incidence of peritonitis secondary to viscus perforation will be examined to determine the most common sites of perforation and associated comorbidities. Methods This is a retrospective observational study based on data collected from the King Fahad Hospital of the University (KFUH). This research targeted patients who had viscus organ perforation and the relation of peritonitis secondary to it. The sample was taken from patients under the care of the General Surgery Department from the first of Feb 2016 to the 12th of Sep 2022. The final sample consisted of 450 patients. The method of diagnosis of peritonitis was mainly clinical, and the surgical approach was either through an exploratory laparotomy or a diagnostic laparoscopy. Incidental findings of viscus organ perforation were noted in addition to certain postoperative complications (e.g., adhesions) and hospital stay. Results Analysis of the results showed a significant relation (p<0.001) between viscus organ perforation and peritonitis. The most common comorbidities associated with secondary peritonitis were hypertension (12, 24.5%), diabetes mellitus (10, 20.4%), any abdominal mass (3, 6.1%), and inflammatory bowel disease (1, 2%). However, a chi-square analysis has shown no significant association between peritonitis and the targeted associated comorbidities. Conclusion Perforation of the small intestine carries the biggest association with peritonitis incidence, in addition to comorbidities such as hypertension and diabetes mellitus. Further study to establish the value of these factors might contribute to decreasing the morbidity and mortality of secondary peritonitis.
