Key result
Generalized peritonitis is linked to ~70% higher 30-day mortality vs non-generalized peritonitis after emergency abdominal surgery.
Why the study?
Secondary generalized peritonitis is potentially life-threatening, but its association with short-term mortality and postoperative complications after major emergency abdominal surgery required investigation.
Does generalized peritonitis increase short-term mortality and postoperative complications in patients undergoing major emergency abdominal surgery?

In patients undergoing major emergency abdominal surgery, generalized peritonitis is an independent risk factor for increased 30- and 90-day mortality and severe postoperative complications.
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.

Olausson et al. (2025) conducted a cohort in Major emergency abdominal surgery (n=591). Generalized peritonitis vs. Non-generalized peritonitis was evaluated on 30-day mortality (p=0.033). Generalized peritonitis was associated with a significantly higher 30-day mortality rate compared to non-generalized peritonitis (18.5% vs. 10.9%) in patients undergoing major emergency abdominal surgery.
