【Abstract】 Objective To investigate the origin, prevention and treatment of postoperative complications and death rate after pancreaticoduodenectomy （PD）. Methods Retrospective study on the clinical materials of complications and death rate was done on 106 cases of PD performed in our hospital during July 1985 to December 2002. Results In this group, 37 cases (34.91%) had postoperative complications, and the incidence rate of severe complications was 19.81% (21/106), the death rate was 10.38% (11/106). Compared between the two groups with preoperative bilirubin gt;342 μmol/L and ≤342 μmol/L, the incidence of total complications increased evidently (P＜0.05), and the bleeding amount，infusion amount and operation time in those with complications or dead ones were evidently higher than those without complications (P＜0.05). Conclusion The safty and resectability of PD has improved evidently in recent years but good skills, careful operation, the experience of the operatior and careful perioperative treatment and nursing are of crucial importance to reduce the complications and death rate.

Objective To explore the clinical value of preoperative neoadjuvant chemotherapy (NAC) combined with laparoscopic pancreatoduodenectomy (LPD) with multiple surgical approaches in the treatment of borderline resectable pancreatic head cancer. Methods The clinicopathologic data of 35 patients with critical resectable pancreatic head carcinoma admitted to the Department of Hepatobiliary and Pancreatic Surgery of Luoyang Central Hospital Affiliated to Zhengzhou University and the Department of Hepatobiliary and Pancreatic Surgery of the Fifth Affiliated Hospital of Zhengzhou University from January 2017 to June 2022 were retrospectively analyzed. All patients received NAC before operation (AG protocol). At the end of the course of treatment, according to the type of borderline resectable pancreatic cancer (BRPC) [venous invasion type (BRPC-V type) and arterial invasion type (BRPC-A type)], take the individualized surgical approach for LPD (BRPC-V type: inferior mesenteric vein approach; BRPC-A type: left posterior approach, medial uncinate process approach, anterior approach, or lower mesocolon approach). The intraoperative condition, R0/R1 resection rate, lymph node dissection, postoperative complications, average hospital stay, recovery, follow-up and survival were recorded. Results① Efficacy evaluation of NAC: 13 patients were partially relieved , 17 patients were stable and 5 patients were progressive after 4 weeks of treatment. Five progressive patients continued to receive comprehensive internal medicine treatment, and the remaining 30 patients underwent LPD. ② Intraoperative situation: LPD were successfully completed in 30 patients, 2 patients underwent extended pancreaticoduodenectomy combined with superior mesenteric vein (or) portal vein reconstruction among them. Among the 30 patients with LPD, there were 10 cases of inferior mesenteric vein approach, 10 cases of left posterior approach, 6 cases of medial uncinate process approach, 1 case of left posterior approach+medial uncinate process approach, 2 cases of anterior approach, and 1 case of inferior mesocolon approach. The mean operative time was (379.4±77.3) min, the intraoperative blood loss was (436.9±95.1) mL. ③ Postoperative situation: The incidence rate of postoperative surgery-related complications was 33.3% (10/30), including 4 cases of Clavien-Dindo grade Ⅰ [biliary fistula in 1 case (3.3%), A-grade pancreatic fistula in 1 case (3.3%), gastric draining dysfunction in 1 case (3.3%), diarrhea in 1 case (3.3%)], 5 cases of grade Ⅱ [pulmonary infection in 2 cases (6.6%), B-grade pancreatic fistula in 2 cases (6.6%), abdominal infection in 1 case (3.3%)], and 1 case of grade Ⅲ [gastroduodenal artery stump bleeding (3.3%)]. Among the 10 patients with complications, 9 cases recovered after symptomatic treatment, and 1 case died, with a fatality rate of 3.3% (1/30). The mean postoperative hospital stay was (17.3±5.5) days. ④ Excision rate and pathological results: R0 resection rate was 90.0% (9/10) in 10 patients with BR-PV type LPD, and R1 resection was performed in 1 patient. R0 resection rate was 75.0% (15/20) in 20 patients with BR-A type, and R1 resection was performed in 5 patients (2 patients with medial uncinate process approach; Left posterior approach in 2 cases; Submesocolon approach was used in 1 case). In 30 patients with LPD, the total R0 removal rate was 80.0% (24/30), the number of lymph nodes dissected was (11±5). Pathological type: There were 26 cases (86.7%) of ductal adenocarcinoma in 30 patients, 1 case of adeno-squamous carcinoma (3.3%), 1 case of mucinous carcinoma (3.3%), 2 cases of acinocytic cell carcinoma (6.7%). 23 cases (76.7%) of medium-high differentiation and 5 cases (16.6%) of low differentiation, two cases (6.7%) were undifferentiated. ⑤ Postoperative follow-up and survival: 30 patients were completely followed-up for 6-39 months, with a median follow-up time of 17 months. The median survival time of BRPC-V and BRPC-A patients was 24.0 months and 17.0 months, respectively. The overall survival rates of 30 patients at 1, 2 and 3 years after operation were 77.3%、46.5% and 13.7%, respectively. Conclusion The selection of preoperative NAC combined with individualized surgical approach for patients with borderline resectable pancreatic head cancer is beneficial to improve the radical resection rate and clinical therapeutic effect, and has good clinical application value.
目的 探讨捆绑式胰肠吻合术的改良方法。方法 对8例胰十二指肠切除术患者行捆绑式胰肠吻合术时采用带血管蒂的大网膜包绕空肠浆肌鞘，以达捆绑之目的。8例中行桥袢空肠造瘘5例，胆总管造口T管引流3例，并观察其术后5 d内每天平均引流液量。结果 8例患者均治愈出院，无胰瘘、胆瘘发生； 5 d内每天平均引流液量除第1天胆总管造口低于空肠造瘘外，其余4 d每天平均引流液量均明显高于空肠造瘘； 1例空肠造瘘者术后第8天继发胰腺残端出血，经电灼后止血。结论 带血管蒂的大网膜包绕空肠浆肌鞘完全可以代替粗线环绕空肠结扎，并使整个空肠浆肌鞘与胰腺紧贴，更利于胰肠间愈合； 空肠造瘘或胆总管造口对桥袢空肠均有减压引流的作用，但T管引流更简单、有效、省时。
【Abstract】 Objective To investigate the preoperative and intraoperative evaluation and the operative methods of pancreaticoduodenectomy combined with resection of involved blood vessel. Methods The materials of 226 cases of carcinoma of head of pancreas, which were collected from January 2002 to June 2005, were assessed according to the T-grade evaluative method and were summarized into a more accurate method of preoperative and intraoperative evaluation and an operative method of the pancreaticoduodenectomy combined with vascular resection. The statistical analyses were performed by SAS 6.12 Stat software package with χ2 test for categorical data. Results The coincidence of every preoperative evaluations on pancreaticoduodenectomy with T-grade method were more than 85.00% and the accurate rate of evaluation on relationship between tumor and blood vessel was 80.97%. As the degree of T-grade increased, the proportion of requiring pancreaticoduodenectomy combined with vascular resection increased significantly as well (P＜0.001). All operations were smoothly done and the reconstruction of removed vascular took 12 to 46 minutes. The complication rate and the mortality rate of perioperative period were 19.61% and 1.96%, respectively. Conclusion With more practice, experience and the advanced imaging technology, it is possible for professional surgeon to evaluate more accurately on the pancreaticoduodenectomy combined with vascular resection by using the preoperative T-grade method. T-grade evaluative method is useful for operator to assess the indication accurately and to design the operative schedule reasonably. Accurate operational evaluation and careful operation are also important for pancreatoduodenectomy combined vascular resection.
ObjectiveTo summarize the clinical experience of 58 operations for biliary malignant tumor with da Vinci surgical system. MethodsFrom January 2009 to October 2010, 180 patients with hepatopancreaticobiliary and gastrointestinal disease underwent robotic surgeries by using da Vinci surgical system, including 58 patients with biliary malignant tumor. The case distribution, intra and postoperative data were analyzed. ResultsOf 58 patients, 3 patients with intrahepatic bile duct cystadenocarcinoma received wedge resections of liver. In 36 patients with hilar cholangiocarcinoma, anatomical left hemihepatectomies were performed in 3 cases, resection of extrahepatic duct and gallbladder bridge type biliary revascularization in 3 cases, resection of extrahepatic duct and biliary-enteric Roux-en-Y anastomosis in 14 cases, tumor resection and revascularization of hepatic portal bile duct in 1 case, palliative external drainage of intrahepatic bile duct in 5 cases, and Y-internal drainage of hepatic portal in 10 cases. In 10 patients with gallbladder carcinoma, resection of extrahepatic duct and gallbladder and biliaryenteric Roux-en-Y anastomosis in 2 cases, cholecystectmy in 3 cases, cholecystectmy and external drainage of intrahepatic bile duct in 1 case, cholecystectmy and Y-internal drainage by suspension of hepatic portal in 4 cases. A patient with middle bile duct cancer received radical resection of cholangiocarcinoma and biliary-enteric Roux-en-Y anastomosis. Of 8 patients with distal bile duct cancer, Whipple procedure were performed. Of 58 patients, 2 cases converted to hand-assistant procedure (3.4%). For all patients, operation time was (6.18±1.71) h, blood loss was (116.66±56.06) ml, blood transfusion was (85.55±38.28) ml, ambulation time was (9.10±2.91) h, feeding time was (14.95±4.35) h, and hospital stay was (12.81±4.29) d. Postoperative complications occurred in 8 cases (13.8%), including bile leakage (3 cases), wound bleeding (1 case), pancreatoenteric anastomotic leakage (2 cases), pulmonary infection (1 case), and renal failure (1 case). Of these 8 cases, 6 cases recovered smoothly and 2 cases die of severe pulmonary infection and renal failure after conservative treatment (3 or 4 weeks), therefore, the mortality of patients was 3.4%. In 36 patients with hilar cholangiocarcinoma, 19 cases died (on 2 monthes 4 cases, on 6 monthes 5 cases, on 10 monthes 8 cases, and on 12 monthes 2 cases after operation), 11 cases survival well (gt;26 monthes 4 cases, gt;22 monthes 3 cases, and gt;19 monthes 4 cases), and 6 cases required hospitalization. Of 10 patients with gallbladder carcinoma, 7 cases died (on 3 monthes 1 case, on 5 monthes 1 case, on 8 monthes 1 case, on 11 monthes 3 cases, and on 12 monthes 1 case after operation) and 3 cases survival (gt;17 monthes 2 cases, gt;13 monthes 1 case). In 8 cases undergoing pancreatoduodenectomy, 5 cases died (on 4 monthes 2 cases, on 6 monthes 2 cases, and 10 monthes 1 case after operation) and 3 cases survived well over 2 years. Three patients with intrahepatic bile duct cystadenocarcinoma survived over 1 year. Conclusionsda Vinci surgical system can carry out all kinds of surgery for biliary malignant tumor, especially prominent in the complicated surgeries for hepatic portal, which breaks through the restricted area of laparoscope in hepatobiliary malignant tumor.
ObjectiveTo evaluate the various methods in prevention of pancreatic fistula after pancreaticoduodenectomy.MethodsThe literatures over the years related to prevention of pancreatic fistula were reviewed.ResultsManagement of the pancreatic stump following pancreaticoduodenectomy played the most important role in preventing pancreatic fistula. None of the methods of pancreatic stump had proved to be perfect in preventing pancreatic fistula, though pancreaticojejunostomy was the most widely practiced reconstruct strategy in varieties of option. For pancreaticojejunostomy and pancreaticogastrostomy, the rate of this complication was 12.3% and 11.1%,respectively. In recent years, a new procedure, bindingup pancreaticoduodenectomy, had shown a promise and excellent results in prevention of pancreatic fistula, the rate of fistula was 0 for consecutive 100 cases after pancreaticoduodenectomy.ConclusionBindingup pancreaticojejunostomy have a definite effect to avoid pancreatic fistula and be worthy of being recommended
Objective To evaluate the application of a surgical method in pancreaticoduodenectomy. Methods All the 211 cases of purse-string invaginated pancreaticojejunostomy performed from Dec.1985 to Dec.2007 were reviewed. Firstly, an accordant plastic tube was put and fastened in main pancreatic duct, and pancreas was ligated at 2-3 cm apart from the pancreatic stump to let secretin flow far away. Furthermore, invaginated pancreaticojejunostomy was performed to get closer between pancreas and jejunum. Results Pancreatic fistula and perioperative death didn’t occur among these 211 cases. The complications included 2 cases of incision dehiscence, 4 cases of biliary fistula and 1 case of scission of superior mesentric artery. Conclusion Purse-string invaginated double-layer anastomosis of pancreaticojejunal would be feasible for pancreaticoduodenectomy preventing pancreatic fistula.
