Objective To systematically review the effectiveness of endoscopic dacryocystorhinostomy (En-DCR) with versus without Mitomycin C (MMC) for nasolacrimal obstruction. Methods Databases such as PubMed, EMbase, CENTRAL (Issue 12, 2012), VIP, WanFang Data, CBM and CNKI were electronically searched to collect the randomized controlled trials (RCTs) which investigated the comparison between En-DCR with and without MMC for nasolacrimal obstruction. The searched data was updated to December 31st, 2012. According to the inclusion and exclusion criteria, literature was screened, data were extracted, and the methodological quality of the included studies was also assessed. Then, meta-analysis was performed using RevMan 5.2.0 software and the quality of evidences was graded using GRADEpro 3.6 software. Results A total of 9 RCTs were included in the meta-analysis. The results of meta-analysis showed that, the recovery rate in the MMC group was significantly elevated (RR=1.13, 95%CI 1.04 to 1.22, P=0.003), the area of ostium in the MMC group was bigger at 1, 6 and 12 months than in the control group, postoperatively (MD=6.68 mm2, 95% 5.43 to 7.94, Plt;0.000 01; MD=11.61 mm2, 95%CI 4.67 to 18.55, P=0.001; MD=15.65 mm2, 95%CI 2.95 to 28.34, P=0.02), respectively, but the area of ostium in the MMC group at the third month was bigger than that in the control group (MD=8.20 mm2, 95%CI –6.67 to 23.08, P=0.28). The operative time was significantly prolonged in the MMC group (MD=10.1 min, 95%CI 8.00 to 12.20, Plt;0.000 01). Conclusion En-DCR combined with MMC could improve the recovery rate and prevent the over shrinkage of ostium area effectively due to nasolacrimal obstruction.
Objective To evaluate the clinical effectiveness of endoscopic third ventriculostomy (ETV) and ventriculal peritoneum shunt (VPS) for hydrocephalus. Methods A fully recursive literature search was conducted in PubMed (1996 to June, 2011), EMBASE (1996 to June, 2011), Cochrane Central Register of Controlled Trials (Issue 3, 2011), CBM (1996 to June, 2011), CNKI and Wanfang Database (1996 to June, 2011) in any language. The randomized or non-randomized controlled trials of hydrocephalus treated by endoscopic third ventriculostomy and ventriculal peritoneum shunt were considered for inclusion. The analyzed outcome variables were overall complications and the survival rate of all time points. Data related to clinical outcomes were extracted by two reviewers independently. Statistical analyses were carried out by using RevMan 5.0 software. Results Nine published reports of eligible studies involving 1 187 participants met the inclusion criteria. Compared with VPS, ETV had no significant differences in short-term (1 or 2 years) survival rate (RR=1.02, 95%CI 0.90 to 1.16, P=0.74; RR=1.14, 95%CI 1.00 to 1.30, P=0.06), but there were significant differences between the two groups in overall complication rate (RR=0.70, 95%CI 0.57 to 0.89, P=0.001), postoperative 3-year survival rate (RR=1.23, 95%CI 1.07 to 1.41, P=0.004), and postoperative 5-year survival rate (RR=1.14, 95%CI 1.29 to 1.66, P=0.05). So the outcomes indicated ETV was superior in controlling the overall complication rate and prolonging the long-term survival rate. Conclusion Current evidence suggests that endoscopic third ventriculostomy is superior to ventriculal peritoneum shunt in reducing the overall complications and prolonging the long-term survival rate, but there is no significant difference in short-term survival rate between the two methods. The effectiveness of the two operational methods for hydrocephalus caused by all specific reasons still has to be further proved by more high-quality, multi-centered and double-blind RCTs.
Objective To explore primary surgical treatment experience of typeⅣ hilar cholangiocarcinoma. Methods From April 2008 to April 2011，20 patients with type Ⅳ hilar cholangiocarcinoma were enrolled into the same surgical group in Department of Hepatobiliary and Pancreatic Surgery of West China Hospital of Sichuan University.The intra- and post-operative results were analyzed.Results The total resection rate was 75%，which was consisted of 10 cases of radical excision and 5 cases of non-radical excision.Seven patients received left hepatic trisegmentectomy and caudate lobe resection including anterior and posterior right hepatic duct reconstruction，hepatojejunostomy，and Roux-en-Y jejunojejunostomy.Six patients received enlarged left hepatic trisegmentectomy and caudate lobe resection including left intrahepatic and extrahepatic duct reconstruction，hepatojejunostomy，and Roux-en-Y jejunojejunostomy. Two patients received quadrate lobe resection including two cholangioenterostomies after anterior and posterior right hepatic duct reconstruction，and left intrahepatic and extrahepatic duct reconstruction.After percutaneous transhepatic cholangial drainage （PTCD） and portal vein embolization （PVE），two patients with total bilirubins ＞400 mmol/L received radical excision and non-radical excision，respectively.Three patients only received PTCD during operation due to wide liver and distant metastasis，and two patients received T tube drainage during operation and postoperative PTCD due to left and right portal vein involvement. All 15 patients who received lesion resection survived more than one year， whereas another five patients whose lesions can not been resec ted only survived from 3 to 6 months with the mean of 4.2 months.No death occurred during the perioperative period. Conclusions For patients with type Ⅳ hilar cholangiocarcinoma， preoperative evaluation and tumor resection shall conducted so as to relieve obstruction of biliary tract，otherwise PTCD and PVE prior to the final lesion resection shall be performed.
Objective To investigate the best management in treating relapsed biliary calculi after endoscopic sphincterotomy (EST).Methods The clinical data of 96 patients with relapsed biliary calculi after EST in our hospital from February 1999 to February 2009 were retrospectively analysed. The patients were grouped into two groups by the size of calculi under magnetic resonance cholangiopancreatography: surgical group (the size of calculi was bigger than 1.0 cm) in 79 cases and non-surgical group (the size of stone was smaller than 1.0 cm and the patients were performed EST again) in 17 cases. The relapsed biliary calculi rate between two groups were compared. Results In the surgical group, the 79 patients (82.29%) were performed common bile duct exploration, transected common bile duct and choledochojejunostomy with Roux-en-Y anastomosis. In the non-surgical group, the 17 patients (17.17%) were performed EST again. The relapsed biliary calculi rate was 2.63% in the surgical group, 70.59% in the non-surgical group. There was marked difference in the relapsed biliary calculi rate between surgical group and non-surgical group (Plt;0.05). Conclusion The operation treatment is the best way for relapsed biliary calculi after EST, and has good curative effect. The best manner of operation treatment is common bile duct exploration, transected common bile duct and choledochojejunostomy with Roux-en-Y anastomosis.
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.
ObjectiveTo prospectively study the effect of preventing postoperative reflux esophagitis with esophagogastrostomy and RouxenY gastrojejunostomy after proximal subtotal gastrectomy.MethodsTwentysix cases of carcinoma of the gastric fundus and cardia were allocated randomly to 2 groups (the control group with 12 cases and the experimental group with 14 cases) according to odd or even number of the admission number.After proximal subtotal gastrectomy and esophagogastrostomy, the control group underwent pyloroplasty while the experimental group with pyloruspreserving RouxenY gastrojejunostomy.The inflammatory reaction of the tissue obtained at the esophagogastric junction using a fiber gastroscope was observed after half year of postoperative followup in the two groups.An examination of gastric emptying of a radionuclidelabeled test meal were performed.According to the Visick score of followup data,the effects of operation were evaluated.The 5year survival rate was also evaluated.ResultsThe postoperative gastrointestinal symptoms in the experimental group were slighter than those in the control group.The examination of gastric emptying of a radionuclidelabeled test meal showed that the gastric emptying time of a half dose,gastric remains rates of radionuclide after 10 min and 60 min in the experimental group were similar to those in the control healthy people group.But in the control group,the gastric emptying time of a half dose delayed,and the gastric remains rate of radionuclide after 10 min and 60 min were higher than the other groups.The biopsy study of the esophagogastric junction showed that the inflammatory reaction in the experimental group was slighter than that in the control group.There was no significant difference between the two groups in the survival rate.ConclusionFor patients with carcinoma of the gastric fundus and cardia, after proximal subtotal gastrectomy and esophagogastrostomy,compared with pyloroplasty,pyloruspreserving RouxenY gastrojejunostomy can decrease the reflux esophagitis,and relieve the postoperative gastrointestinal symptoms.
Objective To investigate the choleenterostomy type and the longterm results in treatment of benign diseases of biliary tract. MethodsA total of 614 cases of choleenterostomy from January 1981 to December 2000 were followed up and analysed. The original diseases: 321 were original hepatolithiasis and/or bileduct stricture (52.3%)， 106 congenital cyst of common bile duct (17.3%), 151 iatrogenic bile duct injury (24.6%) and others 36 cases (5.9%). Choledochoduodenostomy was performed in 89 cases and choledochojejunostomy in 525 cases. Five hundred and twentyfour cases have been followed up for 1 to 20 years. The rate of followup was 87.9%. ResultsIn 84.5% of the cases, excellent or good longterm results were achieved. Reoperation rate were 49.4% in cases of choledochoduodenostomy or cystoduodenostomy, 14.2% in sideside (cyst) cholangiojejunostomy and 4.4% in endside cholangiojejunostomy, respectively. Conclusion The choledochoduodenostomy should be abolished. The endside cholangiojejunostomy shoud be the best choice when it is needed to perform choledochojejunostomy in benign bile duct diseases and can promise a satisfactory longterm result.
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 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.
To evaluate the feasibility, safety and effectiveness of enteral nutrition (EN) via jejunostomy in the early postoperative period in patients with acute hemorrhagic necrotizing pancreatitis (AHNP), 38 patients were divided into the early group (start EN 3 or 4 days after operation) and the later group (start EN 7 days after operation). All patients received parenteral nutrition at first, then were transited to EN. The enteral nutrition liquid was transfused by continuous drip via jejunostomy in both groups. Levels of serum amylase, blood glucose, as well as the liver function were used as indices of tolerance. Symptoms and physical signs of abdominal pain as well as the level of serum albumin were used as the indices of effectieness. Patients tolerated the therapy well in both groups. Moreover, they enjoyed an earlier correction of hypoalbuminemia with more quickly improved serum albumin and no abdominal pain. Starting enteral nutrition in the early postoperative period is feasible, safe and efficacious for acute hemorrhagic necrotizing pancreatitis patients. It plays an important role in treating AHNP and improving curing rate.
