RESUMO
Objective:To investigate the classification of main pancreatic duct and treatment strategy after linear stapler closure of pancreatic neck in laparoscopic pancreaticoduodenectomy (LPD).Methods:The records of 51 consecutive patients with LPD who were treated by linear staple closure technique of pancreatic neck from February to December 2022 from Binzhou Second People′s Hospital, Shijingshan Campus, Beijing Chaoyang Hospital, Capital Medical University, Rizhao Hepatobiliary-Pancreatic-Splenic Surgery Research Institute, Chaoyang Central Hospital, Shandong Juxian People′s Hospital, Weihai Municipal Hospital, Binzhou Central Hospital, and Affiliated Hospital of Chifeng University were retrospectively reviewed. According to the visibility, position and diameter of the main pancreatic duct at the stump of the pancreas, the type of main pancreatic duct was divided into type I, type Ⅱ, type Ⅲa and type Ⅲb. The number of cases in each main pancreatic duct classification and the corresponding treatment strategies were examined.Results:A total of 51 cases of LPD were successfully completed. Of these patients, the males comprised 56.9%(29/51), and females comprised 43.1%(22/51), with age ranging from 31 to 88 years old. The type of the main pancreatic duct at the stump of the pancreas included 7 cases (13.7%) of type Ⅰ, 39 cases (76.5%) of type Ⅱ, 2 cases (3.9%) of type Ⅲa, and 3 cases (5.9%) of type Ⅲb. Corresponding treatment strategies were adopted according to different main pancreatic duct types, the main pancreatic duct was successfully found, and a support drainage tube was inserted.Conclusion:After linear stapler closure of pancreatic neck, corresponding treatment strategies should be adopted according to the classification of the main pancreatic duct, which would help to improve the success rate of finding the main pancreatic duct and placing a support drainage tube.
