ObjectiveTo investigate the effect of drained versus nondrained pancreaticojejunostomy on prevention of the pancreatic leakage after pancreaticoduodenectomy. MethodsSeventysix patients underwent the standard pancreaticoduodenectomy including resection of the distal stomach,common bile duct, the head of pancreas and the duodenum.Pancreaticenteric reconstruction was accomplished via either pancreaticojejunostomy by endtoside anastomsis or pancreaticojejunostomy by ducttomucosa anastomsis.The stented external drainage of pancreatic duct was used in 45 of 76 patients. ResultsPancreatic leakage was identified in 1 patient in the drained group consisting of 45 patients,in 7 patients in the nondrained group consisting of 31 patients, the incidence of pancreatic leakage in the drained group (2.2%) was significantly less than in the nondrained group (22.6%,P＜0.05).ConclusionComparing the incidences of pancreatic leakage from both groups,the authors believe that the stented external drainage of pancreatic duct can significantly reduce the incidence of pancreatic leakage after pancreaticoduodenectomy.
Objective To evaluate the effectiveness and safety of early enteral nutrition (EN) versus total parenteral nutrition (TPN) after pancreaticoduodenectomy (PD). Methods Such databases as MEDLINE, EMbase, The Cochrane Library, CBM, VIP, CNKI were electronically searched to collect the randomized controlled trials (RCTs) about EN versus TPN after PD published from 2000 to March 2010. The quality of the included trials was assessed according to the inclusive and exclusive criteria, and the data were extracted and analyzed by using RevMan 5.0 software. Results A total of 4 RCTs involving 322 PD patients were included. The meta-analysis showed that the EN (the treatment group) was superior to the TPN (the control group) in the average postoperative hospital stay (MD= –2.34, 95%CI –3.91 to –0.77, Plt;0.05), the total incidence rate of complication (RR=0.75, 95%CI 0.57 to 0.99, P=0.04), the recovery time of enterocinesia (MD= –29.87, 95%CI –33.01 to –26.73, Plt;0.05) and the nutrition costs (MD= –30.51, 95%CI –35.78 to –25.24, Plt;0.05); there were no differences in mortality (RR=0.23, 95%CI 0.03 to 2.03, P=0.19), pancreatic leakage (RR=0.78, 95%CI 0.45 to 1.35, P=0.38), infectious complications (RR=0.71, 95%CI 0.43 to 1.18, P=0.19), non-infectious complications (RR=0.78, 95%CI 0.5 1 to 1.20, P=0.26) and postoperative serum albumin level (MD= –0.79, 95%CI –2.84 to 1.27, P=0.45). Conclusion Compared with total parenteral nutrition, the enteral nutrition used earlier after pancreatoduodenectomy shows significant advantages. But more reasonably-designed and double blind RCTs with large scale are expected to provide high quality proof.
ObjectiveTo investigate the age of patients can be the independence factor to affect the feasibility of pancreaticoduodenectomy. MethodsThe cases in the First Affiliated Hospital, Xinjiang Medical University from Feb. 2011 to Feb. 2015 were retrospectively analyzed, and divided into six groups according to age < 50, 50≤age < 60, 60≤age < 70, 70≤age < 75, 70≤age < 80, and≥80 years old. The complications, hospitalization days, and mortality rates for six groups were analyzed. ResultsThe differences in ASA classification (P < 0.001), hypertension (P < 0.001), coronary heart disease (P=0.001), diabetes mellitus (P < 0.001), heart failure (P=0.001), respiratory failure (P=0.037), postoperative hospitalization days (P=0.014), and delayed gastric emptying grade C (P=0.006) had statistical significance, and pancreatic fistula (P=0.058), postoperative bleeding (P=0.786), and mortality (P=0.125) of the different age groups had no significant difference. ConclusionAge is not the independent risk factor to affect the feasibility of pancreaticoduodenectomy, but the strictly preoperative comorbidities assessment is necessary.
ObjectiveTo analyze the risk factors for pancreatic fistula following pancreaticoduodenectomy. MethodThe clinical data of 150 patients underwent pancreaticoduodenectomy in this hospital from January 2011 to January 2014 were reviewed, and the potential factors for pancreatic fistular were evaluated by both univariate and multivariate analysis. ResultsThe incidence of pancreatic fistula was 12.7% (19/150). Univariate analysis results showed that the age, preoperative high bilirubin level, texture of the remnant pancreas, diameter of wirsung, operative time were associated with pancreatic fistula following pancreaticoduodenectomy (P < 0.05). Multivariate logistic regression analysis results revealed that the texture of the remnant pancreas, diameter of wirsung, and operative time were the inde-pendent risk factors (P < 0.05) for pancreatic fistula following pancreaticoduodenectomy. ConclusionsTexture of the remnant pancreas, diameter of wirsung, operative time are independent risk factors for pancreatic fistula following pancreaticoduodenectomy. Rich experience and skilled surgical procedures could effectively reduce the incidence of pancreatic fistula.
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.
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.
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.
ObjectiveTo introduce the method of laparoscopic pancreaticoduodenectomy through an arterial approach, and to evaluate the clinical value of this technique. MethodsThe clinical data of 19 patients with periampullary carcinoma, distal bile duct cancer, and early-stage pancreatic head carcinoma that underwent laparoscopic pancreaticoduodenectomy through an arterial approach in the Department of Hepatobiliary and Pancreatic Surgery, Sun Yat-sen Memorial Hospital between September 2010 and July 2013 were retrospectively analyzed. The patients were followed-up until February 28, 2014. ResultsLaparoscopic pancreaticoduodenectomy were successfully performed in all 19 cases, there were no need to convert to open surgery. Open reconstruction was performed in 2 cases, and 17 cases underwent total laparoscopic reconstruction of the digestive tract. The duration of the operations ranged from 5-10.5 h(mean 6.3 h), and the intra-operative blood loss ranged from 170-430 mL(mean 250 mL). Post-surgical pathology detected a mean number of 13.7 lymph(9-21) nodes in all patients. No deaths occurred during the perioperative period. Complications were observed in 42.1%(8/19) of the subjects, including 5 cases with pancreatic fistula, 1 case with bile leak, 1 case with gastric emptying disorder, and 1 case with a gastroduodenal artery aneurysm. The mean length of hospital stay was 10.7 d(7-19 d). The mean followed-up period was 7.5 months(2-28 months), there were 6 patients died of tumor metastasis or recurrence during the followed-up. ConclusionLaparoscopic pancreaticoduodenectomy through an arterial approach simplifies pancreaticoduodenectomy and lymph node dissection procedures, and can completely remove lymph nodes.
ObjectiveTo explore the risk factors of intraabdominal complications (IACs), pancreatic fistula (PF), and operative death after pancreatoduodenectomy (PD), and to provide a theoretical basis in reducing the rates of them. MethodsClinical data of 78 patients who underwent standard PD surgery in The Third People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from Jun. 2003 to Nov. 2011 were collected to analyze the influence factors of IACs, PF, and operative death. ResultsThere were 29 cases suffered IACs (13 cases of PF included), and 6 case died during 1 month after operation. Univariate analysis results showed that IACs and PF occurred more often in patients with soft friable pancreas, diameter of main pancreatic duct less than 3 mm, preoperative biliary drainage, no pancreatic duct stenting, and without employment of somatostatin (P < 0.05), no influence factor was found to be related to operative death. Multivariate analysis results showed that patients with no pancreatic duct stenting (OR=1.867, P=0.000), soft texture of remnant stump (OR=1.356, P=0.046), and diameter of main pancreatic duct less than 3 mm (OR=2.874, P=0.015) suffered more IACs; PF was more frequent in patient with no pancreatic duct stenting (OR=1.672, P=0.030), soft texture of remnant stump (OR=1.946, P=0.042), and diameter of main pancreatic duct less than 3 mm (OR=1.782, P=0.002);no independent factor was found to have relationship with operative death. ConclusionsSoft texture of remnant stump, diameter of main pancreatic duct less than 3 mm, and no pancreatic duct stenting are independent risk factors that should be considered in indications for PD surgery.
【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.
