Objective To evaluate the linkage between the proxmal as well as long term outcome and choice of therapeutical modality for benign hilar stricture of bile duct prospectively. Methods 25 patients have been catergorized into 4 groups according to different pathogen and the proxmal as well as long term outcome after pathogen based management have been studied prospectively. Results The hepatic portal cholangio-jejunostomy applied for iatrogenic hilar stricture of bile duct has been proved to be effective and the incidence of refulux cholangitis is only 10%(1/10). Hepatic hilar plasty procedures keep the physiological entitity of bile duct and the vital, sufficient autologous repair materials as well as reliable operation design are needed. Resection of atrophic right liver lobe bearing hepatolithiasis combined hepatic hilar plasty has reached both elimination of liver focus and maintaining the physiological entitity of bile duct. The ballon dilation for mild ring-like hilar stricture of bile duct is valide but not for hilar tubular stricture of secondary sclerosing cholangitis.Conclusion The strategy of individualized management (pathogen based management) for benign hilar stricture of bile duct has proved to be reliable and effective.
Objective To explore the clinical value of early enteral nutrition in severe acute pancreatitis （SAP） by percutaneous endoscopic gastrostomy/jejunostomy （PEG/J）.Methods Treatment condition of nighty patients with SAP were retrospectively analysed.The 90 patients were collected peripheral venous blood respectively on 1， 12， and 18 d after admission to hospital.Forty-five of them were in PEG/J group， the others were in control group. Serum IL-6，TNF-α and endotoxin were detected by enzyme-linked immunosorbent assay （ELISA），CD4 /CD8 was determinated by indirect immunofluorescence staining method （FITC-labeled）.Results On 12 d and 18 d，the levels of serum IL-6， TNF-α， and endotoxin in PEG/J group were lower than those in control group （P＜0.01）.The CD4 /CD8 was significantly higher than that in control group （P＜0.01）.In control group， 2 cases complicated upper gastrointestinal haemorrhage，4 cases complicated pancreatic pseudocysts， and 2 cases complicated double infection， the temperature became normal after about 13.5 d.In PEG/J group， there were not upper gastrointestinal haemorrhage and double infection，but 2 cases also complicated pancreatic pseudocysts， the temperature became normal after about 10.5 d.Conclusion The clinical effectiveness of early enteral nutrition in SAP by PEG/J is satisfactory.
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.
The secondary anastomotic stenosis is often occured from the repair and reconstructive operation of the injured bile duct. It is difficult to treat and the outcome is serious. In order to prevent this complication, the fibrin glue instead of traditional suturing technique combined with inner support was used. Fifty-four hybrid dogs were divided into 3 groups. Group A received Roux-en-y choledochojejunostomy with fibrin glue; group B received Roux-en-y choledochojejunostomy, with a fibrin glue combined support left permanently in the bile duct and group C received Roux-en-y choledocholejejunostomy with fibrin glue combined a support left temporarily in the bile duct. The amount of collagen in the scar was measured at 3/4, 3, 6, 9, 12 months respectively after operation. The results showed: 1. the mature period of scar was shortened from 12 months to 9 months when fibrin glue instead of suture was used in choledochojejunostomy; 2. the mature period of scar was further shortened from 9 months to 6 months when fibrin glue combined with inner support instead of fibrin glue was used in choledochojejunostomy. The conclusions were as follows: 1. fibrin glue could facilitate the healing of wound by inhibiting the formation of scar and accelerrate the maturation of scar; 2. when the inner support was used with fibrin glue in the operation, the mature period of scar could be further shortened; 3. the mechanism of action of the fibrin glue included minimizing the injury, avoiding foreign-body reaction, modifying organization of hematoma, preventing formation of biliary fistular and enhancing intergration and cross-linkage of collagen.
Objective To explore surgery strategy of reoperation for type Ⅳa congenital choledochal cyst. Methods The patient was a 20-year-old female with repeated right upper abdominal pain and fever for more than 1 year and aggravation for more than 1 month, and the choledochal cyst excison was performed 15 years ago. The MRI revealed that a huge cyst located in the left lobe of liver, with multiple intrahepatic calculus. The patient was diagnosed with a type Ⅳa congenital choledochal cyst and choledochojejunostomy later and the intrahepatic dilated bile duct was untreated. Results The cystic dilatation of the intrahepatic bile duct was confirmed during the reoperation, and the multiple stones with pus formation were seen, the color of the right liver was normal and the anatomical left hemihepatectomy was performed. The original anastomosis had no stenosis then was preserved. An about 1.5 cm length of extrahepatic bile duct was dissociated from the upper of anastomosis, and the extrahepatic bile duct was cut open and explored with a choledochoscope. The T-tube drainage was performed following removing the stone. The patient recovered well and was discharged smoothly following the surgery. The cholangiography 6 weeks later revealed that the biliary tract was patency and there was no residual stone. There was no jaundice or fever afterwards. Conclusion Complete excision of choledochal cyst and hepaticoduodenostomy is widely accepted as a standard surgery for type Ⅳa congenital choledochal cyst.
ObjectiveTo investigate the clinical effect of end-to-side binding pancreaticojejunostomy.MethodsFrom March 2009 to December 2019 , 70 patients (pancreatic head cancer in 16 cases, duodenal papillary cancer in 27 cases, bile duct cancer in 8 cases, periampullary cancer in 2 cases, gallbladder cancer invading the pancreatic head in 1 case, intraductal papillary myxoma of pancreas in 6 cases, and mass-type chronic pancreatitis in 10 cases) were performed with end-to-side binding pancreaticojejunostomy were retrospectively analyzed, including large pancreas remnant (n=4). The main procedures included isolation of the pancreatic remnant, incising the jejunal wall and preplacing with seromuscular purse string suture around the incision, performing end-to side binding pancreaticojejunostomy.ResultsThe procedures were successful in all 70 patients. Postoperative complications included pancreatic fistula (n=3, 4.3%), of three patients cured with reoperation, jejunal loop decompression tube was not placed in 2 patients, and 1 patient had pancreatic fistula and bleeding on the eighth day after operation. One out of 3 patients developing abdominal hemorrhage which reoperation died of acute respiratory distress syndrome, 1 patient was cured with the vascular interventional hemostasis. Gastrointestinal anastomotic bleeding (n=1) and adhesive intestinal obstruction (n=1) were cured with reoperation, biliary leakage (n=1) was cured with conservative treatment.ConclusionEnd-to-side binding pancreaticojejunostomy is simple, safe and reliable.
Objective To investigate the risk factors of infection after radiofrequency ablation in patients with liver metastases after choledochojejunostomy. Methods The clinical data of patients with liver metastases treated by radiofrequency ablation in our hospital from January 2010 to April 2022 were collected retrospectively and analyzed by univariate and multivariate logistic regression analysis. Results A total of 57 patients were included in the study, and the total number of postoperative infections was 19 (33.33%). Univariate logistic regression analysis showed that the tumor location, maximum tumor diameter, number of tumors, ablation times, and ablation duration were related to the occurrence of infection after radiofrequency ablation (P<0.01). The results of multivariate logistic regression analysis showed that the tumor location [OR=6.45, 95%CI (1.11, 37.35), P=0.037] and ablation duration [OR=1.49, 95%CI (1.16, 1.91), P=0.002] were independent risk factors for infection after radiofrequency ablation in patients with choledocho-jejunostomy. Conclusions For patients with metastatic liver cancer with a history of choledochojejunostomy, the tumor location and the duration of ablation are closely related to postoperative infection. We should strengthen the indivi-dualized management of such patients during and after operation should be strengthened to promote disease recovery.
Objective To evaluate the application effect of modified jejunostomy in thoracoscopic Ivor-Lewis esophagectomy. Methods A retrospective analysis of patients who underwent Ivor-Lewis esophagectomy for middle and lower esophageal cancer from 2017 to 2023 in our department was performed. The patients from 2017 to 2020 receiving "C+I" in the upper jejunum according to the "C+I" model, and fistula fixed with only two purse-string sutures and the abdominal wall were allocated into a group A. The patients from 2021 to 2023, on the basis of "C+I" suture, the jejunum and abdominal wall fixed with 3-0 absorbable thread for 1-2 needles at the proximal or distal end of the fistula 10-15 mm, and the upper jejunum and abdominal wall fixed into "curtain" were allocated into a group B. The operation time, jejunostomy time, postoperative pathological stage, and enteral nutrition-related complications such as the incidence of incomplete intestinal obstruction, closed loop intestinal obstruction and intestinal volvulus requiring secondary surgery, skin redness and swelling of intestinal fluid leakage, stoma tube blockage, and accidental extubation were compared between the two groups. Results All patients successfully completed Ivor-Lewis esophagectomy under thoracoscopy. There was no perioperative death. There were 118 patients in the group A, including 72 males and 46 females, with an average age of 64.58±6.30 years. There were 125 patients in the group B, including 76 males and 49 females, with an average age of 65.11±6.81 years. There was no statistical difference in operation time, jejunal fistula time, fistula blockage or accidental extubation rate between the two groups (P>0.05). There was a statistical difference in the incidence of incomplete intestinal obstruction (P=0.035), and closed loop intestinal obstruction requiring secondary surgery (P=0.017). There were 36 patients of eczema-like changes in the patients with severe intestinal leakage and redness in the group A, and 7 patients of intestinal leakage and redness in the group B (P<0.001). Conclusion The modified jejunostomy can significantly reduce the incomplete intestinal obstruction, closed loop intestinal obstruction and secondary operation rate after "C+I" jejunostomy, and significantly improve the leakage of intestinal fluid at the stoma and the injury of surrounding skin and soft tissue. Improvements in certain technologies reduce operational difficulties and is worthy of promotion and application in clinical practice.
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 evaluate the safety and efficacy of Roux-en-Y reconstruction with isolated pancreatico-jejunostomy after pancreaticoduodenectomy. MethodsSystematically literature search was performed through PubMed, EMBASE, Cochrane Library, Wanfang, VIP, and CNKI from the earliest to November 30, 2015. Randomized clinical trials (RCTs) and controlled clinical trials (CCTs) comparing outcomes of Roux-en-Y reconstruction with isolated pancrea-ticojejunostomy and conventional pancreaticojejunostomy were searched. The data were applied meta-analysis by RevMan 5.3. ResultsSeven trials were involved, two RCTs including 367 patients and five CCTs including 431 patients. Meta-analysis result showed that there was no statistic significant difference in pancreas fistula between Roux-en-Y reconstruction with isolated pancreaticojejunostomy and conventional pancreaticojejunostomy. ConclusionRoux-en-Y reconstruction with isolated pancreaticojejunostomy after pancreaticoduodenectomy is not superior to conventional pancreaticojejunostomy regarding pancreatic fistula rate or other relevant outcomes.
