【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.
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 investigate effect of sealing one-layer anastomosis in pancreaticojejunostomy in patients underwent pancreaticoduodenectomy. MethodsThe clinical data of 85 patients underwent pancreaticoduodenectomy in this hospital from January 2014 to May 2015 were collected. Of all the patients, 28 patients were underwent sealing onelayer anastomosis in pancreaticojejunostomy (sealing one-layer anastomosis group), 27 patients were underwent ductto-mucosa pancreaticojejunostomy (duct-to-mucosa anastomosis group), and 30 patients were underwent end-to-side invaginated pancreaticojejunostomy (end-to-side invagination group). The anastomosis time, time to pull out drainage tube, postoperative hospital stay, and incidence rate of postoperative pancreatic fistula were compared among these three groups. Results①The anastomosis time (min) of the sealing one-layer anastomosis group was significantly shorter than that of the duct-to-mucosa anastomosis group or end-to-side invagination group (12.51±2.96 versus 25.65±3.35, P < 0.05; 12.51±2.96 versus 23.73±5.27, P < 0.05).②The time to pull out drainage tube of the sealing one-layer anastomosis group was significantly shorter than that of the end-to-side invagination group (7.65±1.30 versus 11.15±3.47, P < 0.05).③The postoperative hospital stay had no statistical significances among these three groups (P > 0.05).④The incidence of pancreatic fistula was 3.57% (1/28), 7.41% (2/27), and 10.00% (3/30) among the sealing one-layer anastomosis group, duct-to-mucosa anastomosis group, and end-to-side invagination group respectively, which had no statistical differences among these three groups (P > 0.05). ConclusionSealing one-layer anastomosis in pancreaticojejunostomy might be a safe anastomosis, and it has advantages of simple operation and short operation time.
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 systematically review the efficacy and safety of enhanced recovery after pancreaticoduodenectomy surgery (ERAS).MethodsPubMed, EMbase, The Cochrane library, CBM, CNKI and VIP databases were electronically searched to collect clinical controlled trials of comparing ERAS and the traditional rehabilitation management in patients who received pancreaticoduodenectomy from inception to March 31st, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.2 software.ResultsA total of 12 non-randomized historical controlled trials involving 2 588 patients were included. The results of meta-analysis showed that ERAS shortened postoperative hospital stay (MD=–5.44, 95%CI –7.73 to –3.15, P<0.000 01) and the time to the first passage of flatus (MD=–1.40, 95%CI –2.60 to –0.20,P=0.02), reduced the rate of postoperative complication (OR=0.61, 95%CI 0.52 to 0.72, P<0.000 01), pancreatic fistula (OR=0.81, 95%CI 0.66 to 0.99,P=0.04) and delayed gastric emptying (OR=0.49, 95%CI 0.38 to 0.63, P<0.000 01). However, there was no significant difference in incidences of biliary fistula, abdominal cavity infection, wound infection and postoperative pulmonary infection between two groups.ConclusionsThe application of ERAS in pancreaticoduodenectomy is effective and does not increase postoperative complication. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
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.
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.
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.
ObjectiveTo assess the safety for removing nasogastric tube(NGT)within postoperative 24 h in Whipple pancreaticoduodenectomy (PD)patients. MethodsThe clinical data of 310 patients performed classic Whipple PD from January 2008 to March 2013 in this hospital were analyzed retrospectively. The patients were divided into early (≤24 h after operation)removing NGT group and late( > 24 h after operation)removing NGT group according to the time of NGT duration. The ratio of NGT reinsertion, time of solid diet tolerance, hospital stay, mortality, and major complications associated with PD were compared between two groups. Results①The demography and preoperative comorbidities characteristics were similar(P > 0.05).②There was no statistical difference of ratio of NGT reinsertion between two groups(P=0.450).③The differences of rates of major complications associated with PD and mortality were not statistically different(P > 0.05)by univariate analysis, but the rate of total complications in the early removing NGT group was significantly lower than that in the late removing NGT group (P=0.014)by multivariate analysis.④The average time of solid diet tolerance(P=0.013)and average hospital stay(P < 0.001)in the early removing NGT group were significantly shorter than those in the late removing NGT group. ConclusionFor patients comfort, NGT following PD should be removed as early as possible even immediately after extubation for selective patients.
Objective To explore the risk factors and treatment associated with postoperative hemorrhage after pancreaticoduodenectomy. Methods The clinical data of 78 patients undergoing pancreatieoduodeneetomy from May 2009 to October 2011 were retrospectively analyzed in Xinhua Hospital, Shanghai Jiao Tong University School of Medicine. Results The incidence of postoperative hemorrhage was 10.3％ （8/78）. Among these eight patients, intra-abdominal hemorrhage occurred in two cases （one case of early and delayed hemorrhage respectively）, and gastrointestinal hemorrhage occurred in 6 cases （one and five cases of early and delayed hemorrhage respectively）. Univarlate analysis showed that operative blood loss, postoperative celiac infection, pancreatic fistula, and pancreaticogastrostomy were significantly associated with postoperative hemorrhage. Multivariate analysis identified for vailables as independent factors associated with postoperative hemorrhage, namely, pancreaticogastrostomy, postoperative celiac infection, and pancreatic fistula. Conclusions Skillful operation, prevention of pancreatic fistula, and control celiac infection are important for reducing postoperative hemorrhage. Proper treatments should be used according to the site, onset, and severity of hemorrhage. To prevent its occurrence is the key of treatment.
