Objective To analyze the effect of inner diameter of pancreatic duct following pancreaticoduodenectomy on pancreatic fistula. Methods From January 1995 to December 2008, 256 patients underwent pancreaticoduodenectomy were divided into four groups based on the types of pancreaticojejunostomy: end-to-side “mucosa-to-mucosa” anastomosis group (n=115), end-to-end “mucosa-to-mucosa” anastomosis group (n=71), end-to-end invaginated pancreaticojejunostomy group (n=43) and pancreaticogastrostomy group (n=27). Alternatively, 238 patients were divided into two groups according to drainage ways: stenting tube for internal drainage group (n=132) and stenting tube for external drainage group (n=106). Furthermore, 233 cases were divided into three groups on the basis of inner diameter of pancreatic duct: ≤0.2 cm group (n=54), 0.2-0.4 cm group (n=93) and ≥0.4 cm group (n=76). Then, the incidence rate of pancreatic fistula of each group was compared. Results The incidence of pancreatic fistula was 8.20% (21/256). The incidence of pancreatic fistula for different types of pancreaticojejunostomy was as follow: end-to-side “mucosa-to-mucosa” anastomosis group (7.83%， 9/115), end-to-end “mucosa-to-mucosa” anastomosis group (7.04%, 5/71), end-to-end pancreaticogastrostomy invaginated group (13.95%, 6/43) and pancreaticogastrostomy group (3.70%, 1/27), in which there wasn’t significant difference in 4 groups （χ2=2.763，P=0.430）. There was no significant difference of the incidence of pancreatic fistula between stenting tube for internal drainage group (9.10%, 12/132) and stenting tube for external drainage group (8.49%, 9/106), χ2=0.126, P=0.722. The incidence of pancreatic fistula in ≥0.4 cm group, 0.2-0.4 cm group and ≤0.2 cm group was respectively 0, 15.05% (14/93) and 11.11%(6/54), and the difference was significant (χ2=12.009, P=0.002). No correlation was found between the incidence of pancreatic fistula of different inner diameter of pancreatic duct and the types of pancreaticojejunostomy (χ2=1.878， P=0.598). Conclusion The inner diameter of pancreatic duct is an important factor for postoperative pancreatic fistula. No relationship is found between the types of pancreaticojejunostomy and pancreatic fistula in this study.
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.
【Abstract】ObjectiveTo determine the risk factors associated with development of pancreatic fistula after pancreatoduodenectomy (PD). Methods The clinical data of 123 consecutive patients who underwent PD from Dec. 1994 to Dec. 2003 were analysed retrospectively. Results The incidence of pancreatic fistula was 11.4% (14/123). Univariate analysis showed history of upper abdominal operation, texture of pancreas, postoperative serum hemoglobin level, type of pancreatojejunostomy and diameter of pancreatic duct were significantly associated with pancreatic fistula after PD. Multivariate analysis using Logistic regression identified four variables as independent factors associated with the occurrence of pancreatic fistula: history of upper abdominal operation, texture of pancreas, postoperative serum hemoglobin level and type of pancreatojejunostomy. Conclusion History of upper abdominal operation, soft texture of pancreas, postoperative serum hemoglobin level less than 90 g/L and routine invaginated pancreaticojejunostomy are main risk factors associated with development of pancreatic fistula after PD.
ObjectiveTo investigate the application of imbedding pancreaticojejunostomy in pure laparoscopic pancreaticoduodenectomy. MethodsEighty-five cases of laparoscopic pancreaticoduodenectomy in our hospital from May 2014 to December 2015 were analyzed retrospectively. According with inclusion criteria and exclusion criteria, 78 cases were investigated. They were divided into pancreatic duct-to-jejunum mucosa pancreaticojejunostomy group as controlled group (n=42) and imbedding pancreaticojejunostomy (technique of duct-to-mucosa PJ with transpancreatic interlocking mattress sutures) group as modified group (n=36). The rates of pancreatic fistula, abdominal infection/abscess, bile leakage, delayed gastric emptying, gastrointestinal/intraabdominal hemorrhage, pulmonary infection, and incision infection were investigated as well as hospital stays and pancreaticojejunostomy time in two groups were compared. ResultsThe rate of pancreatic fistula especially B to C grade pancreatic fistula in the modified group was obviously lower compared with which in the controlled group (8.3% vs. 31.0%, P < 0.05), pancreaticojejunostomy time ofmodified group was significantly shortened [(35.6±12.4) min vs. (52.8±24.6) min, P < 0.05] and total operative time also shortened [(322.4±23.6) min vs. (384.2±30.2) min, P < 0.05). There were no significant difference of the rates of abdominal infection/abscess, bile leakage, delayed gastric emptying, gastrointestinal/intraabdominal hemorrhage, pulmonary infection, ?incision infection, and hospital stays (P > 0.05)]. Conciusions The type of pancreaticojejunostomy has a significant impact on the rate of pancreatic fistula after laparoscopic pancreaticoduodenectomy. Imbedding pancreaticojejunostomy can decrease the rate of pancreatic fistula after operation, and shorten the pancreaticojejunostomy time and total operative time.
Pancreatic and biliary duct fistula are the most severe and common complication following pancreatoduodenectomy. To prevent this complication, anastomosis should be appropriately performed and drainage of the pancreatic and bile duct is crucial. For proper drainage, the authers designed a cross-shaped tube for both the pancreatic and bile duct drainage, which has been practised on 16 patients with no pancreatic and biliary fistula happened. This new model combines the internal and external pancreatic drainages with biliary T-tube drainage and gives better drainage in practice so that the leakage might be lessened.
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.
Objective To investigate the new method of pancreaticoenterostomy and decrease the probability of complications like pancreatic fistula etc. Methods By using the absorbable bandage and ear-brain glue, modified sutureless pancreaticoenteromy was made in 10 swines. Experimental data includes： routine analysis of blood, levels of amylase in blood and abdominal drainage and lipase in blood and abdominal drainage. The tissues in anastomosis were taken for pathology examination in 1 month after operation. Results The average operative time was （35±10） min.Nine of ten animals had no pancreatic fistula and survived. The levels of amylase and lipase in abdominal drainage were both normal. One swine had a evident abdominal distensile on 2 days after operation, the level of amylase was 10 000u/L,then died on 10 days after operation. Pancreatic fistula and infection were found because of the loss of stent in pancreatic duct. Conclusions Comparison with traditional operation, the modified sutureless pancreaticoenteromy can also control the probability of pancreatic fistula. And this method can be hoped to be one of the routine operations of pancreaticoenterostomy because of its simplicity and practicality.
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 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 explore the clinical value of the improved style of pancreatodeodenectomy. Methods Retrospective analysis the data of 111 cases of pancreatodeodenectomy. Forty-one cases of 111 cases were performed the modified Whipple pancreatic jejunal anastomosis， which reconstruction residual pancreatic duct jejunum into the intestinal mucosa sets of accurate end to side anastomosis type （modified group）. Another 70 cases were performed the conventional Whipple pancreatic jejunal anastomosis， which classic lines set into the pancreas jejunum anastomosis （conventional group）. The incidence rate of pancreatic fistula after operation were compared in two groups. Results The postoperative recovery in modified group was smooth， and there was no case of pancreatic fistula. Thirteen cases （18.57%） had pancreatic fistula in conventional group. The difference of incidence rate of pancreatic fistula between two groups was statistically significant （P＜0.05）. The difference in other complications such as gastrointestinal bleeding， delayed gastric emptying， biliary fistula， abdominal infection， lung infection， and wound infection were no statistically significant （P＞0.05）， and the difference of survival rate was also no statistically significant （P＞0.05） in two groups. Conclusions Pancreatic duct jejunum end to side into the mucous membrane of the mucosal anastomosis sets of pancreatodeodenectomy can significantly prevent pancreatic fistula， it is worth to promote the use in clinical work.
