ObjectiveTo evaluate the postoperative complications after pancreaticoduodenectomy with modified triple-layer(MTL) duct-to-mucosa pancreaticojejunostomy and with resection of jejunal serosa, analyse the risk factors of pancreatic fistula, and compare effects with two-layer(TL) duct-to-mucosa pancreaticojejunostomy.
MethodsData on 184 consecutive patients who underwent the two methods of pancreaticojejunostomy during standard PD between January 1, 2010 and January 31, 2013 were collected retrospectively. The risk factors of pancreatic fistula were investigated by using univariate and multivariate analyses.
ResultsA total of 88 patients received TL and 96 underwent MTL. Rate of pancreatic fistula for the entire cohort was 8.2%(15/184). There were 11 fistulas(12.5%) in the TL group and four fistulas(4.2%) in the MTL group(P=0.039). Body mass index, pancreatic texture, pancreatic duct diameter, and methods of pancreaticojejunostomy had significant effects on the formation of pancreatic fistula on univariate analysis. Multivariate analysis showed that pancreatic duct diameter less than 3 mm and TL were the significant risk factors of pancreatic fistula.
ConclusionsMTL technique effectively reduced the pancreatic fistula rate after PD in comparison with TL, especially in patients with pancreatic duct diameter less than 3 mm.
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 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 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 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 risk factors of gastric paralysis following pancreaticoduodenectomy so as to offer help for prevention and treatment of gastric paralysis.
MethodDomestic and international literatures about gastric paralysis following pancreaticoduodenectomy were collected, diagnostic criteria, risk factors, and the latest progress of gastric paralysis were summarized.
ResultsGastric paralysis is one of the most common postoperative complications following pancreaticoduodenectomy. It might be caused by many risk factors, such as operation method, gastrointestinal anastomosis, abdominal complications, chronic hyperglycemia, and excess infusion, etc.
ConclusionsAlthough definition of gastric paralysis by ISGPS is widely adopted, it fails to distinguish gastric paralysis from impaired gastric function related to other postoperative complications and it might result in an overestimation of its true morbidity. The risk factors of occurrence of gastric paralysis are still in controversy and results of research in different centers are not same, more prospective randomized controlled trials are needed.
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.
Objective To analyze the difference in the incidence of postoperative pancreatic leakage and anasto-motic bleeding complications in various methods of pancreaticojejunostomy after pancreaticoduodenectomy （PD）. Methods The clinical data of 526 patients underwent pancreaticojejunostomy from January 2008 to September 2012 in this hospital were analyzed retrospectively. End-to-side “pancreatic duct to jejunum mucosa-to-mucosa” anastomosis （abbreviation：mucosa-to-mucosa anastomosis） was performed in 359 patients， which contained 149 patients with internal drainage， 130 patients with external drainage， and 80 patients with no drainage. End-to-side invaginated anastomosis was performedin 165 patients without drainage. In addition， side-to-side anastomosis was performed in 2 patients without drainage.Results There were 34 cases （6.46%） of pancreatic leakage， 8 cases （1.52%） of anastomotic bleeding in pancreaticoje-junostomy， and 32 cases of death （6.08%）. ① The pancreatic leakage rate of mucosa-to-mucosa anastomosis was signi-ficantly lower than that of end-to-side invaginated anastomosis 〔4.18% （15/359） versus 11.52% （19/165）， χ2=10.029， P=0.002〕. There was no significant difference of the anastomotic bleeding incidence between mucosa-to-mucosa anasto-mosis and end-to-side invaginated anastomosis 〔1.67% （6/359） versus 1.21% （2/165）， χ2=0.159， P=0.691〕. ② In the mucosa-to-mucosa anastomosis group， the pancreatic leakage rates in the ones with internal drainage and external drainage were lower than those in the ones without drainage， respectively （2.68% （4/149） versus 11.25% （9/80）， χ2=7.132， P=0.008；1.54% （2/130） versus 11.25% （9/80）， χ2=9.410， P=0.002）；which was no significant difference between the ones with internal drainage and external drainage 〔2.68% （4/149） versus 1.54% （2/130）， χ2=0.433， P=0.510〕. But there were no significant differences for both the pancreatic leakage 〔2.68% （4/149） versus 1.54% （2/130）， χ2=0.433， P=0.510〕and anastomotic bleeding incidence 〔2.68% （4/149） versus 1.54% （2/130）， χ2=0.433， P=0.510〕 between the ones with internal drainage and external drainage. Conclusions Mucosa-to-mucosa anastomosis has a lower pancreatic leakage incidence as compared with end-to-side invaginated anastomosis. However， there is no significant difference of the anast-omotic bleeding incidence. Internal or external drainage could reduce the incidence of pancreatic leakage， but have no obvious effect to the anastomotic bleeding incidence.
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 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.
