Abstract:
Objective:To investigate the related factors that affect the occurrence of severe pancreatic fistula after radical gastrectomy.Methods:The clinical data of 460 patients undergoing radical gastrectomy in The People's Hospital of Shouguang from January 2015 to January 2021 were retrospectively analyzed. These patients were divided into severe pancreatic fistula group ( n = 24) and non-severe pancreatic fistula group ( n = 436) according to whether they developed severe pancreatic fistula after surgery. Preoperative clinical data, surgical data, and abdominal drainage fluid amylase level in the first postoperative days were compared. The receiver operating characteristics (ROC) curve was used to calculate the cutoff value of abdominal drainage fluid amylase level on the 1 st and 3 rd days of developing severe pancreatic fistula after radical gastrectomy. The incidence of pancreatic fistula was compared between different amylase level groups. Multivariate logistic regression was performed to analyze the independent risk factors of severe pancreatic fistula after surgery. Results:There were significant differences in body mass index, operative time, intraoperative blood loss, peritoneal drainage fluid amylase level on the 1 st and 3 rd days after surgery, and the number of cases undergoing splenectomy between the two groups (all P < 0.05). The cutoff values of amylase level in peritoneal drainage fluid (D-AMY) on the 1 st and 3 rd days after surgery were 2 156 IU/L and 596 IU/L respectively, which had high sensitivity and specificity. On the 1 st and 3 rd days after surgery, the incidence of pancreatic fistula in the high-level amylase group was significantly higher than that in the low-level amylase group [26.2% (16/61) vs. 0.8% (3/334), χ2 = 62.82, P < 0.05). Multivariate logistic analysis showed that obesity, splenectomy, and abdominal drainage fluid amylase level higher than the cut-off value on the 1 st and 3 rd days after surgery were independent risk factors for severe pancreatic fistula, and the differences were statistically significant (all P < 0.05). Conclusion:Obesity, splenectomy, and abdominal drainage fluid amylase level higher than the cut-off value on the 1 st and 3 rd days after surgery are independent risk factors affecting the occurrence of severe pancreatic fistula. D-AMY (> 2 156 IU/L) on the 1 st day and D-AMY (> 596 IU/L) on the 3 rd day in the early postoperative days can be used as cutoff values to predict the occurrence of severe pancreatic fistula after radical gastrectomy.
