自1985年第一例腹腔鏡膽囊切除術成功，腹腔鏡逐漸成為治療結石性膽囊疾病的金標準。近10年來其應用范圍迅速擴展，并被廣大普外科醫生接受和認可，開創了醫學領域高速發展的歷史新紀元。急腹癥是指能夠引起急腹痛的腹腔內急性病變，要求外科醫生做出快速、準確判斷，而不允許花費更多的時間做全面的輔助檢查。要想做出快速診斷又不耽誤病情，近年來微創外科同行認識到腹腔鏡兼有診斷和治療的特點，在外科急腹癥中發揮了重要的作用，現分述之。
ObjectiveThis review aimed to summarize the current epidemiological status and risk factors of pancreatic cancer at home and abroad.MethodThe literatures on epidemiology and risk factors of pancreatic cancer in recent years were collected and summarized.ResultsCurrently the overall incidence of pancreatic cancer was lower in all malignant tumors, but the mortality rate was the opposite. Incidence varies from region to region, the incidence rate in economically developed areas was higher than that of underdeveloped areas. Although the disease had made some progress in the fields of surgery, chemotherapy, an so on, the long-term survival of patients with pancreatic cancer was still not ideal. The onset of pancreatic cancer was associated with smoking, alcohol, obesity, dietary imbalance, age, gender, blood type, ethnicity, family history and genetic history, chronic pancreatitis, infection, and intestinal flora imbalance.ConclusionsPancreatic cancer is a high malignancy with a poor prognosis. It is influenced by a variety of risk factors. Therefore, it is especially necessary to pay attention to the primary prevention of pancreatic cancer and screen high-risk individuals regularly, to diagnose pancreatic cancer at an early stage.
ObjectiveTo investigate the occurrence and treatment of postoperative complications after laparoscopic laparoscopic pylorus-preserving pancreaticoduodenectomy (LPPPD) or pancreaticoduodenectomy (LPD). MethodThe clinical data of 130 patients undergoing LPD from October 2010 to December 2015 in West China Hospital of Sichuan University were analyzed retrospectively. ResultsOf 130 patients, postoperative complications occurred in 55 cases, including 24 cases of pancreatic fistula, 14 cases of gastric emptying disorder, 3 cases of anastomotic bleeding, 6 cases of peritoneal infection, 1 case of bile leakage, 1 case of venous thrombosis, 1 case of chylous leakage, 5 cases of peritoneal effusion, without the occurrence of stress ulcer and incision complications. There were significant difference in the incidence of pancreatic fistula (P=0.025), gastric emptying disorder (P=0.034), anastomotic bleeding (P=0.020), and peritoneal infection (P=0.016) among prophase group, metaphase group, and the later stage group. ConclusionsThe most common complication after LPD is pancreatic fistula. With the improvement of surgical techniques and procedures, incidences of some postoperative complications decreases gradually.
ObjectiveTo study the predictability of dynamic prediction model of clinical pancreatic fistula in patients with or without pancreatic duct stent in laparoscopic pancreaticoduodenectomy (LPD).MethodsA total of 66 patients who underwent LPD in West China Hospital of Sichuan University from November 2019 to October 2020 were enrolled in the randomized controlled trial (registration number: ChiCTR1900026653). The perioperative data of the patients were collected in real time. The patients were divided into groups according to whether the pancreatic duct support tube was retained during the operation, and the probability prediction value was output according to the model formula. The specificity, sensitivity, accuracy, discrimination, and stability of the prediction results were analyzed.ResultsFor the group with pancreatic stent tubes, the specificity, sensitivity, and accuracy of the model at the model cut-off points on the postoperative day 2, 3 and 5 were 92.0%, 76.7% and 57.1%, 50.0%, 100% and 66.7%, and 88.8%, 78.8% and 61.3%, respectively. The areas under the ROC curve were 0.870, 0.956 and 0.702, respectively. The kappa values of the prediction result based on model cut-off point and cut-off point of ROC curve were 0.308, 0.582 and 0.744, respectively. Whereas for those who without the stent tube, the specificity, sensitivity, and prediction accuracy of the model on the postoperative day 5 were 66.7%, 100% and 72%, respectively. The area under curve at different time points were 0.304, 0.821, and 0.958, respectively. The kappa values at the last two time points were 0.465 and 0.449, respectively.ConclusionsFor patients with pancreatic duct support during LPD operation, the dynamic model of clinical pancreatic fistula can more accurately screen high-risk groups of clinical pancreatic fistula, and has better stability of prediction results. For patients without supporting tube, in the case of flexible adjustment of the boundary point, the model can also be more accurate screening on the 3rd and 5th days after operation.
