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.
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.
Objective To explore the diagnostic and treating scheme of primary sclerotic cholangitis. Methods 24 cases of primary sclerotic cholangitis identified by radiological and pathological examinations from 1972 to 1998 were analysed retrospectively. According to Thompson, 1 case was classified as type Ⅰ, 5 cases were type Ⅱ, 10 cases were type Ⅲ and 8 cases were type Ⅳ. The operation were as follows,resection of gallbladder plus T tube drainage in 8 cases, plus Roux-en-Y anastomosis of bile duct and jejunum in 12 cases, plus U tube stent and drainage in 4 cases. Results The total mortality rate was 25% (6/24) in 2～18 years follow-up after operation. Conclusion Early diagnosis and operation may resolve the drainage of bile into the jejunum. When serious lesions and worse liver functions exist, liver transplantation should be considered.
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.
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.
ObjectiveTo explore the application value of “enfolded pancreatic duct”pancreaticojejunostomy (PJ) during laparoscopic pancreaticoduodenectomy (LPD). MethodsThe clinicopathologic data of patients underwent LPD and “enfolded pancreatic duct” PJ from May 2020 to March 2022 were collected retrospectively. The time of PJ was recorded. And the pancreatic leakage, biliary leakage, chyle leakage, bleeding and infection, and death within 30 d after the operation were observed. ResultsA total of 132 patients were collected, including 60 males and 72 females. The age of patients was (58.6±10.9) years old. There were 38 cases of pancreatic head cancer, 17 cases of duodenum carcinoma, 17 cases of inferior segment cholangiocarcinoma, and 23 cases of duodenal papilla carcinoma, 7 cases of pancreatic neuroendocrine tumor, 11 cases of pancreatic intraductal papilloma, 5 cases of duodenal stromal tumor, 5 cases of duodenal papillary adenoma, 6 cases of pancreatic cyst adenoma, and 3 cases of pancreatic head stone. None of the patients was converted to open surgery. The diameter of pancreatic duct before operation was (3.43±2.11) mm, which were <3 mm in 31 cases. The time of PJ was (20.61±3.16) min. The pancreatic leakage occurred in 17 cases, including 11 cases of grade A leakage, 6 cases of grade B leakage, and none of grade C leakage. There was 1 case of bile leakage, 6 cases of chyle leakage, 5 cases of postoperative bleeding (2 cases of intraabdominal bleeding and 3 cases of gastrointestinal anastomotic bleeding), 3 cases of intraabdominal infection, and no death. None of the patients was readmission due to complications after 90 d of follow-up. ConclusionsFrom summary results of this group of cases, compared with the traditional PJ method, “enfolded pancreatic duct” PJ is less difficult and simpler to operate, which can obviously shorten the PJ time during LPD and reduce the incidence of pancreatic leakage. It is especially suitable for laparoscopic application.
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 investigate the clinical effect of “Double R” pancreatojejunostomy in laparoscopic pancreaticoduodenectomy (LPD).MethodsThe clinical data of 20 patients underwent “Double R” pancreaticojejunostomy in the LPD from November 2018 to December 2019 in this hospital were collected retrospectively. The duration of pancreaticojejunostomy, incidence of postoperative pancreatic fistula, incidence of other complications, mortality, length of stay, and other clinical outcomes were analyzed.ResultsThere were 5 males and 6 females. The age was (56±10) years old. The body mass index was (22.6±4.4) kg/m2. The LPDs were successfully performed in all 20 patients, no patient transferred to the laparotomy, and no patient died within 30 d. There were 6 patients with papillary adenocarcinoma of the duodenum, 5 patients with adenocarcinoma of the lower part of the common bile duct, 2 patients with adenocarcinoma of the pancreatic duct, 3 patients with serous cystadenoma of the pancreatic head, 2 patients with intraductal papillary myxoma of the main pancreatic duct of the pancreatic head, 1 patient with duodenal adenoma with high grade intraepithelial neoplasia, 1 patient with metastatic renal clear cell carcinoma of the pancreatic head, 5 patients with soft pancreas, 12 patients with medium texture, 3 patients with hard texture. The diameter of distal pancreatic duct was (2.1±1.7) mm. The operative time was (380±69) min, the duration of pancreaticojejunostomy was (29±15) min, the intraoperative blood loss was (180±150) mL, the postoperative time of anal exhaust (2.2±0.8) d, postoperative time of fluid intake (3.5±1.1) d, postoperative time of half fluid intake (5.5±0.7) d, postoperative time of hospitalization (14±10) d. There were 3 complications in 2 patients, one of which suffered the pulmonary infection, the other suffered the delayed gastric emptying and gastrointestinal anastomosis bleeding, no bile leakage and abdominal hemorrhage happened. There were 2 cases of pancreatic fistula after the operation, all of them were biochemical pancreatic fistula.Conclusions“Double R” pancreaticojejunostomy method has some advantages of convenient operation, short operation time, and low incidence of pancreatic fistula. However, due to the limited sample size, its safety and feasibility still need to be verified by larger samples and more institutions.
ObjectiveTo compare the clinical outcomes of laparoscopic magnetic compression cholangiojejunostomy (LMCCJ) with laparoscopic hand-sutured cholangiojejunostomy (LHSCJ). MethodsA retrospective case-control study was performed. From January 2019 to May 2022, 37 patients, who underwent laparoscopic treatment in this hospital, were enrolled in this study. There were 16 cases in the LMCCJ group and 21 cases in the LHSCJ group. The demographic information, procedure time to complete bilioenteric reconstruction, postoperative hospital stay, operative complications, magnets expulsion time, and follow-up results were collected and analyzed. ResultsThere were no statistical differences in the baseline data such as the gender, age, composition of primary diseases, preoperative total bilirubin, and preoperative common bile duct diameter between the two groups (P＞0.05). The outer diameter of the magnets was (10.50±0.97) mm, the expulsion time of the magnets was (49.69±37.58) d, and the expulsion rate of the magnets was 100% (16/16). There was no intestinal obstruction or gastrointestinal perforation caused by the retention of the magnets. The procedure time to complete bilioenteric reconstruction in the LMCCJ group was statistically shorter than that in the LHSCJ group [(11.31±3.40) min vs. (24.81±3.40) min, t=11.96, P＜0.01]. There was no statistical difference in the total bilirubin level at the first week after surgery between the two groups (U=142.0, P=0.80). The postoperative hospital stay in the LMCCJ group was longer than that in the LHSCJ group [(28.31±14.11) d vs. (16.19±7.56) d, t=3.36, P＜0.01]. During the perioperative period, there was no bleeding or biliary infection in the two groups, but one case of biliary leak in the LHSCJ group. In all 37 patients were followed-up for (548.8±259.2) d. During the follow-up period, the incidence rates of biliary intestinal anastomosis stenosis, tumor recurrence, and mortality had no statistical differences between the two groups (P＞0.05). ConclusionFrom the results of comparative analysis in this study, it can be concluded that LMCCJ is not only safe equally, but also easier and less time-consuming as compared with LHSCJ.
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.
