AIM: To analyze the risk factors for pancreatic leakage after pancreaticoduodenectomy (PD) and to evaluate whether duct-to-mucosa pancreaticojejunostomy could reduce the risk of pancreatic leakage. METHODS: Sixty-two patients who underwent PD at our hospital between January 2000 and November 2003 were reviewed retrospectively. The primary diseases of the patients included pancreas cancer, ampullary cancer, bile duct cancer, islet cell cancer, duodenal cancer, chronic pancreatitis, pancreatic cystadenoma, and gastric cancer. Standard PD was performed for 25 cases, PD with extended lymphadenectomy for 27 cases, pylorus-preserving PD for 10 cases. A duct-to-mucosa pancreaticojejunostomy was performed for patients with a hard pancreas and a dilated pancreatic duct, and a traditional end-to-end invagination pancreaticojejunostomy for patients with a soft pancreas and a non-dilated duct. Patients were divided into two groups according to the incidence of postoperative pancreaticojejunal anastomotic leakage: 10 cases with leakage and 52 cases without leakage. Seven preoperative and six intraoperative risk factors with the potential to affect the incidence of pancreatic leakage were analyzed with SPSS10.0 software. Logistic regression was then used to determine the effect of multiple factors on pancreatic leakage. RESULTS: Of the 62 patients, 10 (16.13%) were identified as having pancreatic leakage after operation. Other major postoperative complications included delayed gastric emptying (eight patients), abdominal bleeding (four patients), abdominal abscess (three patients) and wound infection (two patients). The overall surgical morbidity was 43.5% (27/62). The hospital mortality in this series was 4.84% (3/62), and the mortality associated with pancreatic fistula was 10% (1/10). Sixteen cases underwent duct-to-mucosa pancreaticojejunostomy and 1 case (1/16, 6.25%) developed postoperative pancreatic leakage, 46 cases underwent invagination pancreaticojejunostomy and 9 cases (9/46, 19.6%) developed postoperative pancreatic leakage. General risk factors including patient age, gender, history of jaundice, preoperative nutrition, pathological diagnosis and the length of postoperative stay were similar in the two groups. There was no statistical difference in the incidence of pancreatic leakage between the patients who received the prophylactic use of octreotide after surgery and the patients who did not undergo somatostatin therapy. Moreover, multivariate logistic regression analysis showed that none of the above factors seemed to be associated with pancreatic fistula. Two intraoperative risk factors, pancreatic duct size and texture of the remnant pancreas, were found to be significantly associated with pancreatic leakage. The incidence of pancreatic leakage was 4.88% in patients with a pancreatic duct size greater than or equal to 3 mm and was 38.1% in those with ducts smaller than 3 mm (P = 0.002). The pancreatic leakage rate was 2.94% in patients with a hard pancreas and was 32.1% in those with a soft pancreas (P = 0.004). Operative time, blood loss and type of resection were similar in the two patient groups. The incidence of pancreatic leakage was 6.25% (1/16) in patients with duct-to-mucosa anastomosis, and was 19.6% (9/46) in those with traditional invagination anastomosis. Although the difference of pancreatic leakage between the two groups was obvious, no statistical significance was found. This may be due to the small number of patients with duct-to-mucosa anastomosis. By further analyzing with multivariate logistic regression, both pancreatic duct size and texture of the remnant pancreas were demonstrated to be independent risk factors (P = 0.007 and 0.017, OR = 11.87 and 15.45). Although anastomotic technique was not a significant factor, pancreatic leakage rate was much less in cases that underwent duct-to-mucosa pancreaticojejunostomy. CONCLUSION: Pancreatic duct size and texture of the remnant pancreas are risk factors influencing pancreatic leakage after PD. Duct-to-mucosa pancreaticojejunostomy, as a safe and useful anastomotic technique, can reduce pancreatic leakage rate after PD. 相似文献

AIM: To analyze the risk factors of pancreatic leakage after pancreaticod uodenectomy. METHODS: We retrospectively reviewed 172 consecutive patients who had undergone pancreaticoduodenectomy at Inha University Hospital between April 1996 and March 2006. We analyzed the pancreatic fistula rate according to the clinical characteristics, the pathologic and laboratory findings, and the anastomotic methods. RESULTS: The incidence of developing pancreatic fistulas in patients older than 60 years of age was 21.7% (25/115), while the incidence was 8.8% (5/57) for younger patients; the difference was significant (P = 0.03). Patients with a dilated pancreatic duct had a lower rate of post-operative pancreatic fistulas than patients with a non-dilated duct (P = 0.001). Other factors, including clinical features, anastomotic methods, and pathologic diagnosis, did not show any statistical difference. CONCLUSION: Our study demonstrated that pancreatic fistulas are related to age and a dilated pancreatic duct. The surgeon must take these risk factors into consideration when performing a pancreaticoduodenectomy. 相似文献

AIM: To investigate the impact of preoperative acute pancreatitis(PAP) on the surgical management of periampullary tumors.METHODS: Fifty-eight patients with periampullary tumors and PAP were retrospectively analyzed. Thirtyfour patients who underwent pancreaticoduodenectomy(PD) and 4 patients who underwent total pancreatectomy were compared with a control group of 145 patients without PAP during the same period.RESULTS: The preoperative waiting time was significantly shorter for the concomitant PAP patients who underwent a resection(22.4 d vs 54.6 d, p 0.001)compared to those who did not. The presence of PAP significantly increased the rate of severe complications(Clavien grade 3 or higher)(17.6% vs 4.8%, p = 0.019)and lengthened the hospital stay(19.5 d vs 14.5 d,p = 0.006). A multivariate logistic regression analysis revealed that PAP was an independent risk factor for postoperative pancreatic fistula(OR = 2.91; 95%CI:1.10-7.68; p = 0.032) and severe complications(OR =4.70; 95%CI: 1.48-14.96; p = 0.009) after PD. There was no perioperative mortality.CONCLUSION: PAP significantly increases the incidence of severe complications and lengthens thehospital stay following PD. PD could be safely performed in highly selective patients with PAP. 相似文献

AIM To analyze the risk factors for pancreatic fistula after pancreaticoduodenectomy.METHODS We conducted a retrospective analysis of 539 successive cases of pancreaticoduodenectomy performed at our hospital from March 2012 to October 2015. Pancreatic fistula was diagnosed in strict accordance with the definition of pancreatic fistula from the International Study Group on Pancreatic Fistula. The risk factors for pancreatic fistula were analyzed by univariate analysis and multivariate logistic regression analysis.RESULTS A total of 269(49.9%) cases of pancreatic fistula occurred after pancreaticoduodenectomy,including 71(13.17%) cases of grade A pancreatic fistula,178(33.02%) cases of grade B,and 20(3.71%) cases of grade C. Univariate analysis showed no significant correlation between postoperative pancreatic fistula(POPF) and the following factors: age,hypertension,alcohol consumption,smoking,history of upper abdominal surgery,preoperative jaundice management,preoperative bilirubin,preoperative albumin,pancreatic duct drainage,intraoperative blood loss,operative time,intraoperative blood transfusion,Braun anastomosis,and pancreaticoduodenectomy(with or without pylorus preservation). Conversely,a significant correlation was observed between POPF and the following factors: gender(male vs female: 54.23% vs 42.35%,P = 0.008),diabetes(non-diabetic vs diabetic: 51.61% vs 39.19%,P = 0.047),body mass index(BMI)(≤ 25 vs 25: 46.94% vs 57.82%,P = 0.024),blood glucose level(≤ 6.0 mmol/L vs 6.0 mmol/L: 54.75% vs 41.14%,P = 0.002),pancreaticojejunal anastomosis technique(pancreatic duct-jejunum double-layer mucosa-to-mucosa pancreaticojejunal anastomosis vs pancreatic-jejunum single-layer mucosa-tomucosa anastomosis: 57.54% vs 35.46%,P = 0.000),diameter of the pancreatic duct(≤ 3 mm vs 3 mm: 57.81% vs 38.36%,P = 0.000),and pancreatic texture(soft vs hard: 56.72% vs 29.93%,P = 0.000). Multivariate logistic regression analysis showed that gender(male),BMI 25,pancreatic duct-jejunum double-layer mucosa-to-mucosa pancreaticojejunal anastomosis,pancreatic duct diameter ≤ 3 mm,and soft pancreas were risk factors for pancreatic fistula after pancreaticoduodenectomy.CONCLUSION Gender(male),BMI 25,pancreatic duct-jejunum double-layer mucosa-to-mucosa pancreaticojejunal anastomosis,pancreatic duct diameter ≤ 3 mm,and soft pancreas were risk factors for pancreatic fistula after pancreaticoduodenectomy. 相似文献

AIM: To establish a scoring system to predict clinicallyrelevant postoperative pancreatic fistula(CR-POPF)after pancreaticoduodenectomy(PD).METHODS: The clinical records of 921 consecutive patients who underwent PD between 2008 and 2013 were reviewed retrospectively. Postoperative pancreatic fistula(POPF) was defined and classified by the international study group of pancreatic fistula(ISGPF).We used a logistic regression model to determine the independent risk factors of CR-POPF and developed a scoring system based on the regression coefficient of the logistic regression model. The optimal cut-off value to divide the risk strata was determined by the Youden index. The patients were divided into two groups(low risk and high risk). The independent sample t test was used to detect differences in the means of drain amylase on postoperative day(POD) 1, 2 and 3. The optimal cut-off level of the drain amylase to distinguish CR-POPF from non-clinical POPF in the two risk strata groups was determined using the receiver operating characteristic(ROC) curves.RESULTS: Grade A POPF occurred in 106(11.5%)patients, grade B occurred in 57(6.2%) patients,and grade C occurred in 32(3.5%) patients. A predictive scoring system for CR-POPF(0-6 points) was constructed using the following four factors: 1 point for each body mass index ≥ 28 [odds ratio(OR) = 3.86;95% confidence interval(CI): 1.92-7.75, P = 0.00],soft gland texture(OR = 4.50; 95%CI, 2.53-7.98, P =0.00), and the difference between the blood loss and transfusion in operation ≥ 800 mL(OR = 3.45; 95%CI,1.92-7.75, P = 0.00); and from 0 points for a 5 mm or greater duct diameter to 3 points for a less than 2 mm duct(OR = 8.97; 95%CI: 3.70-21.77, P = 0.00). The ROC curve showed that the area under the curve of this score was 0.812. A score of 3 points was suggested to be the best cut-off value(Youden index = 0.485). In the low risk group, a drain amylase level ≥ 3600 U/L on POD3 could distinguish CR-POPF from non-clinicalPOPF(the sensitivity and specificity were 75% and85%, respectively). In the high risk group, the best cutoff was a drain amylase level of 1600(the sensitivity and specificity were 77 and 63%, respectively).CONCLUSION: A 6-point scoring system accurately predicted the occurrence of CR-POPF. In addition, a drain amylase level on POD3 might be a predictor of this complication. 相似文献
