Abstract:
Objective:To investigate the clinical features and prognosis of duodenal lateral fistula (DLF), and to explore the high-risk factors affecting its prognosis, so as to improve its treatment outcome.Methods:The regression study was conducted based on the database of the Registration System of Chinese Gastrointestinal Fistula and Intra-Abdominal Infections. DLF patients who were hospitalized from January 1, 2018 to December 31, 2018 and had complete clinical data in the database were selected as the research object. The clinical data included patient gender, age, length of hospital stay, hospitalization costs, intensive care unit (ICU) admission, underlying diseases, primary diseases, direct causes of DLF, complications, treatment and outcomes.Results:A total of 142 patients with DLF were enrolled, including 97 males and 45 females, with a median age of 54 years. The top three primary diseases of DLF were gastrointestinal ulcers and perforations in 33 cases (23.2%), biliary tract disease in 27 cases (19.0%), and trauma in 24 cases (16.9%). There were 117 cases (82.4%) with single DLF, and 25 cases (17.6%) were combined with other fistula. Among the 142 patients, 127 were healed (49 by surgery and 78 self-healing) and 15 (10.6%) died. 14 cases (9.9%) underwent percutaneous catheter drainage, and 18 cases underwent laparotomy drainage. Univariate prognostic analysis showed that advanced age (≥60 years old) (χ 2=6.891, P=0.009), primary diseases as gastrointestinal ulcers/perforations (χ 2=8.515, P=0.004), combined with other fistula (χ 2=5.798, P=0.016), malnutrition (χ 2=5.595, P=0.018), pulmonary infection (χ 2=12.449, P<0.001), hemorrhage (χ 2=6.466, P=0.011), multiple organ dysfunction syndrome(MODS ) (χ 2=37.258, P<0.001), underwent laparotomy drainage (χ 2=6.466, P=0.011) were associated with mortality. Multivariate prognostic analysis confirmed that age ≥60 years old ( OR=44.375, 95% CI: 2.676-735.822, P=0.008), combined with other fistula ( OR=16.54, 95% CI: 1.744-156.913, P=0.015) and MODS ( OR=238.447, 95% CI: 9.496-5 987.78, P=0.001) were independent risk factors of the death for DLF patients. Conclusions:The mortality rate of DLF is still relatively high. Iatrogenic duodenal injury (surgical operation, endoscopic treatment) is the main direct cause of fistula. Advanced age, combined with other fistula and MODS significantly increases the risk of death of patients.
