Abstract

Background: Sepsis is fatal in patients with gastrointestinal perforation (GIP). However, few studies have focused on this issue.

Aim: To investigate the risk factors for postoperative sepsis in patients with GIP.

Methods: This was a retrospective study performed at the Department of General Surgery in our treatment center. From January 2016 to December 2018, the medical records of patients with GIP who underwent emergency surgery were reviewed. Patients younger than 17 years or who did not undergo surgical treatment were excluded. The patients were divided into the postoperative sepsis group and the non-postoperative sepsis group. Clinical data for both groups were collected and compared, and the risk factors for postoperative sepsis were investigated. The institutional ethical committee of our hospital approved the study.

Results: Two hundred twenty-six patients were admitted to our department with GIP. Fourteen patients were excluded: Four were under 17 years old, and 10 did not undergo emergency surgery due to high surgical risk and/or disagreement with the patients and their family members. Two hundred twelve patients were finally enrolled in the study; 161 were men, and 51 were women. The average age was 62.98 ± 15.65 years. Postoperative sepsis occurred in 48 cases. The prevalence of postoperative sepsis was 22.6% [95% confidence interval (CI): 17.0%-28.3%]. Twenty-eight patients (13.21%) died after emergency surgery. Multiple logistic regression analysis confirmed that the time interval from abdominal pain to emergency surgery [odds ratio (OR) = 1.021, 95%CI: 1.005-1.038, P = 0.006], colonic perforation (OR = 2.761, CI: 1.821-14.776, P = 0.007), perforation diameter (OR = 1.062, 95%CI: 1.007-1.121, P = 0.027), and incidence of malignant tumor-related perforation (OR = 5.384, 95%CI: 1.762-32.844, P = 0.021) were associated with postoperative sepsis.

Conclusion: The time interval from abdominal pain to surgery, colonic perforation, diameter of perforation, and the incidence of malignant tumor-related perforation were risk factors for postoperative sepsis in patients with GIP.
