ObjectiveTo summarize the application status and prospect of laparoscopic pancreaticoduodenectomy (LPD).MethodThe relevant literatures about studies of LPD at home and abroad were reviewed.ResultsLPD was a difficult operation, mainly suitable for pancreatic head and periampullary benign and malignant tumors. With the development of laparoscopic techniques in recent years, LPD combined the superior mesenteric vein and portal vein resection and reconstruction, or combined multi-visceral resection was feasible, but the survival benefit of LPD with arterial resection and reconstruction and extended lymph node dissection remained to be discussed. At present, there was no clear requirement on the way to reconstruct the pancreatic fluid outflow tract, but the pancreaticojejunostomy for digestive tract reconstruction was chose by the most surgeons. The most studies had confirmed that LPD was minimally invasive and had a short-term prognosis that was not inferior to that of open pancreaticoduodenectomy. However, the results of large sample analysis about long-term survival rate and oncology results were lacking, so it was difficult to judge the advantages and disadvantages of long-term prognosis of the two methods.ConclusionsLPD is a safe, feasible, reasonable, and effective surgical method. With improvement of laparoscopic technology, LPD is expected to become a standard operation method for treatment of pancreatic head cancer and periampullary carcinoma, and oncology benefits of LPD will be further confirmed in future by large-sample clinical randomized control trials and studies of long-term prognosis follow-up.
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

ObjectiveTo evaluate the predictive value of pancreatic duct diameter and pancreatic gland thickness measured using preoperative CT imaging on pancreatic fistula(PF)following pancreaticoduodenectomy (PD). MethodsOne hundred and fifty-one patients who underwent PD consecutively from January 2013 to April 2014 were reviewed retrospectively. Associations between the gender, age and the pancreatic duct diameter and pancreatic gland thickness from preoperative CT imaging and PF were analyzed. The diagnostic values of the pancreatic duct diameter and pancreatic gland thickness in patients with PF were evaluate by receiver operating characteristic (ROC) analysis. The reliability analysis was done for the pancreatic duct diameter and pancreatic gland thickness by using the intraclass correlation coefficient (ICC). The Spearman rank correlation analysis was done between the pancreatic duct diameter and pancreatic gland thickness. Results①PF occurred in 46 cases (30.1%).②The gender and age were not associated with PF (Gender: χ2=1.698, P=0.193; Age: χ2=0.016, P=0.900). The pancreatic duct diameter and pancreatic gland thickness were associated with PF (Pancreatic duct diameter: OR=0.275, 95% CI 0.164-0.461, P=0.000; Pancreatic gland thickness: OR=1.319, 95% CI 1.163-1.496, P=0.000).③There was no correlation between the pancreatic duct diameter and the pancreatic gland thickness (rs=-0.120, P=0.145).④The area under curve of ROC was 0.814 (95% CI 0.745-0.883, P < 0.001) for the pancreatic duct diameter in predicting the PF, the sensitivity and specificity was 68.6% and 78.3% respectively when the best critical value was 3.5 mm. The area under curve of ROC was 0.762 (95% CI 0.674-0.849, P < 0.001) for the pancreatic gland thickness in predicting PF, the sensitivity and specificity was 63.0% and 85.7% respectively when the best critical value was 31 mm.⑤The ICC of the pancreatic duct diameter and pancreatic gland thickness was 0.984 and 0.992 respectively by two medical diagnostic measurement. ConclusionPancreatic duct diameter and pancreatic gland thickness measured using preoperative CT imaging might be useful in predicting PF following PD.

Forty-five pancreatoduodenectomies had been performed in our hospital from 1981 to 1994, of which 35 cases were diagnosed as carcinomas of Vater’s ampulla or pancreatic head, and 10 (cases) as benign lesions. Through analysis of misdiagnosed cases, the authors emphasize that it is important to take correct history of jaundiced patients in detail according to the character of the jaundice and associated symptoms before any operation done. Secondly, all clinical materials must be thoroughly collected and special examinations for diagnosis should be chosen scientifically to avoid relying only on one sort of examination result as diagnostic standard. Thirdly, during operation the area of pancreatic head should be explored carefully and any lesions in doubt should be examined pathologically by puncture biopsy and frozen section to avoid misdiagnosis and thus performing pancreatoduodenectomy.
Objective To explore the effects of recombinant human growth hormone （rhGH） on senile patients after pancreaticoduodenectomy. MethodsFortysix patients were divided into the therapeutic group (rhGH, n=17) and control group (n=29). Both were treated with parenteral nutrition. In the therapeutic group, rhGH (8 u/d) was given hypodermically for 7 days. After operation the levels of albumin, prealbumin, transferrin, and immunoglobulin were measured. Postoperative fatigue syndrome and the average length of stay in hospital were observed too. ResultsAfter operation the levels of albumin, prealbumin, transferrin, and immunoglobulin in the therapeutic group were significantly higher than those of control group. The degree of postoperative fatigue syndrome in the therapeutic group was less than that of control group. The average length of stay in hospital was significantly shortened. Conclusion The early application of rhGH in senile patients after pancreaticoduodenectomy can enhance immune function, reduce the incidence of infection, promote the postoperative recovery, shorten the average length of stay in hospital,decrease the mortality, increase the safety of operation and improve the postoperative life quality of senile patients.
ObjectiveTo investigate the predictive value of preoperative D-dimer, CA19-9, neutrophil-to-lymphocyte ratio (NLR) in the diagnosis of pancreatic cancer. MethodsThe clinicopathologic data of patients who underwent pancreaticoduodenectomy for pancreatic occupying lesions in the First and Fifth Affiliated Hospitals of Xinjiang Medical University from January 2016 to December 2019 were analyzed retrospectively. According to the pathological characteristics, the patients were divided into pancreatic cancer and pancreatic benign tumour. The gender, age, accompanying diseases, preoperative D-dimer, CA19-9, lymphocyte count, neutrophil count, NLR and so on were compared between them. The receiver operating characteristic (ROC) curves of preoperative D-dimer, CA19-9, and NLR for diagnosis of pancreatic cancer were draw. ResultsA total of 142 patients were collected, including 79 patients with pancreatic cancer and 63 patients with pancreatic benign tumour. Compared with the patients with pancreatic benign tumour, the age was older (P<0.05), the number of neutrophils was more (P<0.05), the number of lymphocytes was less (P<0.05), the preoperative levels of CA19-9 and D-dimer, and the preoperative NLR were higher (P<0.05) for the patients with pancreatic cancer. The multivariate analysis of logistic regression revealed that the preoperative higer CA19-9, D-dimer, and NLR increased the incidence of pancreatic cancer (P<0.05), then the optimal cut-off value of preoperative levels of CA19-9 and D-dimer, and preoperative NLR on diagnosis of pancreatic cancer was 108 U/mL, 306 μg/L and 3.2, respectively, the corresponding area under ROC curve was 0.900, 0.891, 0.768, respectively, and which of combination of preoperative CA19-9, D-dimer, and NLR was 0.931. For the pancreatic cancer patients with preoperative NLR, CA19-9, and D-dimer higher than the optimal cut-off value, the proportions of patients with pTNM stage Ⅲ and lymph node metastasis were higher than those for pancreatic cancer patients with below than optimal cut-off value (P<0.05). ConclusionFrom preliminary study results, preoperative CA19-9, D-dimer, and NLR values have certain values in diagnosis of pancreatic cancer, and diagnostic value of combined detection of 3 indexes is higher than single index.
Objective To investigate the clinical value of " O”continuous biliary-enteric anastomosis combined with percutaneous transhepatic cholangial drainage (PTCD) in pancreaticoduodenectomy (PD). Methods The clinical data of 35 patients with PD who were admitted to Xinyang Central Hospital from June 2015 to June 2017 were retrospectively analyzed. Results All patients completed the " O” continuous biliary-enteric anastomosis combined with PTCD without perioperative death. ① The preoperative indwelling time of PTCD tube was (13.24±3.39) d, total bilirubin (TBIL) was (363.67±12.26) μmol/L on admission and (155.59±17.63) μmol/L on preoperative after PTCD, respectively. ② The operative time was (231.46±18.69) min, the intraoperative blood loss was (158.30±31.33) mL, the diameter of the hepatic ductal segment was (1.3±0.2) cm, and the duration of the " O” continuous biliary-enteric anastomosis was (7.31±1.52) min. ③ After surgery, the indwelling time of PTCD tube was (8.13±1.49) d, the hospitalization time was (27.31±5.49) d. Biliary leakage occurred in 1 case, pancreatic fistula occurred in 5 cases (3 cases of biochemical sputum and 2 cases of B-stage pancreatic fistula), abdominal infection occurred in 2 cases, pneumonia occurred in 3 cases, wound infection occurred in 2 cases. No postoperative biliary-enteric anastomosis stenosis, biliary tract infection, and intra-abdominal hemorrhage occurred. There was no laparotomy patients in this group and all patients were discharged. ④ All patients were followed-up for 180 days after surgery. No death, bile leakage, biliary-enteric anastomotic stenosis, biliary tract infection, pancreatic fistula, gastro-intestinal leakage, and abdominal infection occurred. One case of delayed gastric emptying and 2 cases of alkaline reflux gastritis were cured after outpatient treatment. Conclusions The preoperative PTCD can improve the preoperative liver function and increase the security of PD. " O” continuous biliary-enteric anastomosis is simple, safe, feasible, and has the function of preventing biliary-enteric anastomosis stenosis. For severe jaundice patients with blood TBIL >170 μmol/L, the " O” continuous biliary-enteric anastomosis combined with PTCD is an alternative surgical procedure for PD.
