Background:
Secondary generalized peritonitis is a potentially life-threatening condition. The aim of this study was to investigate the association between secondary generalized peritonitis and short-term mortality and postoperative complications in patients undergoing major abdominal emergency surgery.
Methods:
The study included patients with the age ≥ 18 years undergoing major emergency abdominal surgery in a University Hospital from 2017 to 2019 after the introduction of a perioperative bundle care program. The primary outcome measures were short-term mortality, defined as death within 30 and 90 days after surgery and postoperative complications within 30 days after surgery. Uni- and multivariable logistic regression analyses were performed to evaluate risk factors for 30- and 90-days mortality and 30-days postoperative complications.
Results:
A total of 591 patients were included, of whom 21% (124/591) had generalized peritonitis. The overall 30 day-mortality rate was 12.5% (74/591). Patients with generalized peritonitis had a significantly higher 30-day mortality rate than patients with non-generalized peritonitis 18.5% (23/124) vs. 10.9% (51/467), P = 0.033. Generalized peritonitis was an independent risk factor for 30- and 90- days mortality. There was a significantly higher rate of admission to ICU for patients with generalized peritonitis 39.5% (49/124) vs. 12.6% (59/467), P < 0.001. Patients with generalized peritonitis had significantly higher rates of surgical and non-surgical complication compared to patients with non-generalized peritonitis 87.1% (108/124) vs. 65.7% (307/467), P < 0.001. Generalized peritonitis was an independent risk factor of 30 days postoperative complications.
Conclusion:
In a population undergoing major emergency abdominal surgery treated in a perioperative optimization protocol, generalized peritonitis was an independent risk factor for both 30- and 90-days mortality and postoperative complications.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
