Background: Postoperative gastrointestinal fistula (PGF) is one of the main causes of abdominal infection and perioperative death. This study was designed to investigate the risk factors of PGF, anastomotic fistula (AF), and duodenal stump fistula (DSF) for patients who underwent radical distal gastrectomy. Materials and Methods: In this retrospective observational study, 2652 gastric cancer cases who received radical distal gastrectomy from 2010 to 2020 were selected as research subjects. Subsequently, we adopted the univariate and multivariate logistic regression analysis as statistical method to screen the risk factors for PGF, AF, and DSF, respectively. Results: In univariate analysis, gender (P = .022), operative time (P = .013), intraoperative blood loss (P < .001), tumor diameter (P = .002), and tumor stage (P < .001) were related to PGF. Multivariate logistic regression analysis identified the male (odds ratio [OR] = 2.691, P = .042), massive intraoperative hemorrhage (OR = 1.002, P = .008), and advanced tumor (OR = 2.522, P = .019) as independent predictors for PGF. Moreover, diabetes (OR = 4.497, P = .008) and massive intraoperative hemorrhage (OR = 1.003, P = .010) were proved to be associated with AF, while massive intraoperative hemorrhage (OR = 1.001, P = .050) and advanced tumor (OR = 6.485, P = .005) were independent risk factors of DSF. Conclusions: The gender, intraoperative hemorrhage, tumor stage, and diabetes were expected to be used as predictors of PGF for radical distal gastrectomy.
