Objective To investigate the main characteristics of intro-abdominal microbial infection and the risk factors for it after pancreaticoduodenectomy. Methods Clinical data of 200 patients underwent pancreaticoduodenectomy at the First Affiliated Hospital of Xinjiang Medical University from Sep. 2008 to Sep. 2013 were reviewed retrospectively to investigate the main characteristics of abdominal microbial infection after pancreaticoduodenectomy and risk factors for it. Results Of the 200 patients, cultures of drainage fluids were positive in 78 patients, and 42 of them(21.0%) met the diagnosis of intra-abdominal infection criterion. One hundred and eighty-five pathogenic strains were isolated totally, 64 strains of them(34.6%) were Gram positive cocci, 103 strains(55.7%) were Gram negative bacilli, and 18 strains (9.7%) were fungus. The top 5 kinds of bacteria in order were Staphylococcus aureus(31 strains), Pseudomonas aemginosa(28 strains), Escherichia co1i(22 strains), Klebsiella pneumoniae(18 strains), and Enterococcus faecium (14 strains). Most of the pathogens were resistant to broad-spectrum antibiotics. The resistance rate of Pseudomonas aeruginosa was 60.7%(17/28) to imipenem. Extended spectrum beta lactamases(ESBLs)-producing strains accounted for 22.7%(5/22) and 33.3%(6/18) in Escherichia coli and Klebsiella pneumoniae respectively. The detection rate of methicillin resistant staphylococcus aureus(MRSA) was 45.2%(14/31) in Staphylococcus aureus. Multivariate logistic regression analysis results showed that status of pancreatic fistula and pulmonary infection were the risk factors for intraabdominal infection, patients with high grade of pancreatic fistula(OR=16.252, P=0.003) and with pulmonary infection (OR=2.855, P=0.017) had higher incidence of intra-abdominal infection. Conclusion Gram negative bacilli is the main pathogenic bacteria of abdominal drainage fluids cultivation of microbiology after pancreaticoduodenectomy. Most of them have multi-drug resistance characteristic. Positive prevention and treatment of pancreatic fistula and pulmonary infection can reduce the incidence of intra-abdominal infection.
【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.
【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 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 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 summarize the application and the complications of pancreaticogastrostomy (PG) after pancreaticoduodenectomy(PD). MethodThe domestic and international publications involving the theory, methods, and clinical application of PG were retrieved and reviewed. ResultsPG was gradually concerned on the choice of the method of the digestive tract reconstruction after PD, in view of its advantages in theory and operation. The literatures about PG were increased in recent years. But the discussion of decreasing complications of PG after PD had yet to be unified. ConclusionsPG is one of the important operations of digestive tract reconstruction after PD. The factors of operator and patient should be comprehensively considered in the choice of PG.
Objective To explore how to integrate the various sources of information in designing an evidence-based nursing care plan for preventing gastrointestinal hemorrhage (GIH) after pancreaticoduodenectomy (PD). Method Papers and references about prevention of GIH after PD were searched between September and October 2015, and an evidence-based nursing care plan was drawn up and implemented from November 2015 to January 2016. Results A total of 79 papers were found and of which 17 were aviliable. Thirty-nine patients were cared on the basis of the effective project, of whom one was dignosed with GIH on the 3rd postoperative day and the rate of post-PD hemorrhage was 2.6%. All patients were diacharged on the 6th or 7th postoperative day. Conclusion Exploring evidences under the guidance of scientific method and applying them to clinical nursing can prevent post-PD hemorrhage and improve life quality of patients.
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.
ObjectiveTo summarize the prevention method for pancreatic fistula following pancreaticoduodenec-tomy. MethodLiteratures related to the prevention methods for postoperative pancreatic fistula at home and abroad in recent years were retrieved and summarized. ResultsThe pancreatic fistula was a common complication following pancreaticoduodenectomy. It was mainly caused by preoperative continuous high jaundice, selection of intraoperative anastomosis, and early postoperative pancreatic juice secretion. Trypsinogen was activated by alkaline intestinal juice and then the nearby tissue was digested. Pancreatic juice flowed into abdominal cavity to digest the tissue, then caused serious complications or even death. Through the prevention of drugs, preoperative biliary drainage and intraoperative anastomosis, etc., the incidence of postoperative pancreatic fistula was slightly decreased. ConclusionThe prevention for postoperative pancreatic fistula is an integrated process, and it needs to be ran through the whole perioperative period.
Objective To explore the situation and prevention of pancreaticoduodenectomy perioperative complications. Methods The clinical data of 111 cases of pancreaticoduodenectomy were retrospectively analyzed， and the possible factor of complications was analyzed. Results There were postoperative complications in 48 patients （43.2%）， which one kind complication occurred in 25 cases， two kinds in 15 cases， and three kinds or more in 8 cases. Four cases （3.6%） died after operation. Conclusions Pancreaticoduodenectomy is a higher risk surgery in abdominal operation. Strengthen perioperative prevention and treatment are important measures to reduce morbidity and mortality after pancreaticoduodenectomy.
