The antireflux spur-valvewas originally designed for the Roux-Y cholenterostomy. It is made by plication of the two upper limbs of the "Y" after the removal of the seromusculature from the biliary limb, so that the conjoined wall-in-between will he compassed deviating to the biliary, side to form a spur value. It could successfully stop the reflux due to normal peristalsis or intestinal distension. This value was primarily used in choledochal cyst and biliary atresia for more than 100 cases, and also applielied to many other operations for perventing reflux, including: gastroesophageal refluk-Nissen fundoplication, colon replacement of esophagus, side to side shert-circuit of intestinal obstruction, and Kock scontinent ileoslomny. The detailed procedures were described.
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.
Objective To assess the effectiveness and safety of hand-suture vs. stapling anastomosis in esophagogastrostomy. Methods The following databases such as CBM (1978 to February 2012), VIP (1989 to February 2012), CNKI (1994 to February 2012), WanFang Data (1980 to February 2012), The Cochrane Library, PubMed (1966 to February 2012), EMbase (1974 to February 2012), and relevant webs of clinical trials were searched to collect the randomized controlled trials (RCTs) and quasi-RCTs about hand-suture vs. stapling anastomosis in the incidence of anastomotic leakage following esophagogastrostomy. Moreover, relevant references and grey literature were retrieved on web engines including Google Scholar and Medical Martix, and the Chinese periodicals e.g. Chinese Journal of Oncology were also handsearched. According to the inclusion and exclusion criteria, the literature, was screened, the data were extracted, and the quality of the included studies was assessed. Then meta-analysis was conducted using RevMan 5.0 software. Results A total of 9 RCTs involving 2 202 patients were included. The result of meta-analysis was as follows: the incidence of anastomotic leakage in the stapling anastomosis group was lower than that in the hand-suture anastomosis group (OR=0.43, 95%CI 0.26 to 0.71, Plt;0.01). Conclusion Stapling anastomosis is superior to hand-suture anastomosis in reducing the incidence of anastomotic leakage following esophagogastrostomy. For the limited quality and quantity of the included studies, this conclusion has to be further proved by more high-quality studies.
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.
ObjectiveThis study aimed to discuss the risk factors associated with the delay reversal ileostomy following sphincter-preserving surgery for rectal cancer.MethodsClinical data were collected retrospectively on 130 consecutive patients undergoing defunctioning ileostomy following sphincter-preserving surgery for rectal cancer, between January 2014 and December 2014 in the Sixth Affiliated Hospital of Sun Yat-sen University. According to the reversal time of ileostomy, the patients were divided into two groups, including the delay reversal ileostomy group (≥120 d, n=72) and the normal ileostomy group (<120 d, n=58).ResultsOne hundred and thirty patients were studied (median time to reversal 132 d, range 39–692 d). Logistic regression model showed that adjuvant chemotherapy (OR=14.106, P=0.002), distance of tumor from the anal verge (OR=0.019, P=0.002), and anastomotic leakage (OR=32.440, P=0.001) were significant independent risk factors for delayed reversal. Time to reversal was significantly longer in those patients who had adjuvant chemotherapy, anastomotic leakage, and short distance of tumor from the anal verge.ConclusionAdjuvant chemotherapy, short distance of tumor from the anal verge, and anastomotic leakage are the independent risk factors for delay reversal ileostomy following sphincter-preserving surgery for rectal cancer.
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.
