| Objective:To investigate the relationship between pancreas and peripancreatic arteries in patients with gastric cancer,and to explore the influence of the anatomic position on the degree of pancreatic injury in laparoscopic radical gastrectomy for gastric cancer.Methods:A retrospective evaluation was performed on 30 patients who underwent laparoscopic radical gastrectomy in the Department of General Surgery,Second Hospital of Shanxi Medical University from October 2021 to February 2023.The parameters of the anatomic relationship between peripancreatic arteries and pancreas were evaluated on preoperative computed tomography（CT）images and multiplanar reconstruction（MPR）.The relationship between the parameters and the degree of pancreatic injury was analyzed according to the concentration of amylase in drainage fluid on the first day after operation.Results:Among the 30 patients in this study,the median of the length between the highest point of the pancreatic body surface and the abdominal aorta（LPA）and the length between the highest point of the pancreatic body surface and the root of the common hepatic artery（LPC）were significantly longer in the high-injury group than the low-injury group(52mm vs 39.9mm,PLPA<0.05;31mm vs 23.1mm,PLPC=0.006);Receiver operating characteristic（ROC）curve analysis showed that the cut-off values of LPA and LPC for predicting the severity of pancreatic injury were 46.8 mm and 24.6 mm,,and LPA and LPC were positively correlated with the concentration of amylase in drainage fluid on the first day after operation respectively.(RLPA=0.724,PLPA<0.05;RLPC=0.579,PLPC<0.05).Conclusion:Long LPA and long LPC are associated with high amylase concentration in drainage fluid of gastric cancer patients,and can be used as anatomical parameters of pancreas and peripancreatic arteries to predict the degree of pancreatic injury during laparoscopic radical gastrectomy for gastric cancer. |
