Objective To formulate an individualized evidence-based treatment for a first-diagnosed patient with coronary artery-pulmonary artery fistula. Methods Aiming at the issue of whether interventional operation was necessary for first-diagnosed coronary artery-pulmonary artery fistula or not, the computer retrieval was conducted in the US National Guideline Clearinghouse, The Cochrane Library, PubMed and MEDLINE from 1990 to 2011, to collect and assess the best evidence of relevant systematic reviews, randomized controlled trials, controlled clinical trials and treatment guidelines, in order to be applied in clinical treatment. Results There were 1 clinical guideline for treating coronary artery fistula and 3 different high-quality evidence studies were retrieved. The results showed percutaneous coronary intervention was the best treatment currently. According to the obtained evidence and patient’s willingness, the relevant examinations were taken, and the preoperative preparation for percutaneous coronary intervention was done actively after the patient was admitted. Three days after hospitalization, the selective coronary angiography showed right coronary artery-pulmonary artery fistula and left coronary circumflexus artery-left atrial multiple fistulae, then the percutaneous coronary intervention spring coil embolization was successfully conducted for right coronary artery-pulmonary artery fistula. After operation, bayasprin enteric-coated tablets 0.1 g/d was taken for anti-platelet aggregation and preventing thrombotic diseases. The observation during operation and postoperative 5-day hospitalization showed no relevant complications. Conclusion Percutaneous coronary intervention is safe and effective for the symptomatic patients with coronary artery-pulmonary artery fistula.
Objective To systematically review the effectiveness and safety of flexible ureteroscope lithtripsy (fURL) and percutaneous nephrolithotomy (PCNL) in treating renal calculus. Methods Such databases as MEDLINE, EMbase, The Cochrane Library, CNKI, CBM, VIP, and WanFang Data from January, 1990 to August, 2012 were searched to comprehensively collect the clinical trials that compared fURL and PCNL in treating renal calculus. Two reviewers independently screened studies according to exclusion and inclusion criteria, extracted data, and assessed the methodological quality. Then, meta-analysis was performed using RevMan 5.1 software. Results Eight non-randomized controlled trials involving 536 patients were included. The results of meta-analysis showed that, PCNL was better than fURL in stone clearance (OR=0.26, 95%CI 0.15 to 0.46), but fURL was better than PCNL in postoperative pyrexia (OR=0.1, 95%CI 0.42 to 3.35), the incidence of blood transfusion (OR=0.17, 95%CI 0.03 to 1.00), and the duration of hospitalization (P=0.45, I2=0%). Conclusion Current evidence has proved that PCNL is better than fURL in decreasing stone clearance, fURL is better than PCNL in complication, the duration of hospitalization, and medical costs.
Objective To systematically review the effectiveness and safety of coronary artery bypass grafting (CABG) versus percutaneous coronary stent implantation (PCI) in the treatment of patients with unprotected left main coronary artery disease (ULMCA). Methods Databases including The Cochrane Library (Issue 2, 2012), PubMed, EMbase, CBM, CNKI, WanFang Data and VIP were electronically searched from inception to September 2012 for randomized controlled trials on the effectiveness and safety of coronary artery bypass grafting (CABG) versus percutaneous coronary stent implantation (PCI) for ULMCA; References of the included studies were also retrieved. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of the included studies. Then, meta-analysis was performed using RevMan 5.0. Results Four studies were included involving 1 611 cases, of which, 802 cases are in the CABG group, while 809 cases were in the PCI group. The results of meta-analysis showed that: comparing with PCI, CABG significantly reduced the postoperative repeat revascularization rate (OR=0.45, 95%CI 0.31 to 0.66, Plt;0.000 1), but there was no significant difference between the two groups in reducing the myocardial infarction incidence (OR=1.28, 95%CI 0.47 to 3.48, P=0.63), mortality rate (OR=1.36, 95%CI 0.80 to 2.34, P=0.26), and the incidence of major adverse cardio-cerebral vascular events (OR=0.92, 95%CI 0.66 to 1.28, P=0.61). Conclusion This study indicates that CABG is superior to PCI in reducing postoperative rate of target vessel revascularization. But CABG and PCI are alike in reducing myocardial infarction incidence, mortality rate, and the incidence of major adverse cardio-cerebral vascular events. Due to the limited quantity and quality of the included studies, the above conclusion needs to be verified by more high quality RCTs.
Objective To systematically review the effectiveness and safety of intracoronary glycoprotein IIb/IIIa inhibitors (GPIs) undergoing percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) compared with intravenous administration. Methods Databases including PubMed, EMbase, The Cochrane Library (Issue 9, 2012), Ovid, CBM, CNKI and VIP were electronically searched for randomized controlled trials (RCTs) about intracoronary GPIs administration versus intravenous administration undergoing PCI for ACS from inception to September 30th, 2012. Meanwhile, domestic relevant papers published in recent 1 year were also retrieved manually. References of the included studies were retrieved, too. According to the inclusion and exclusion criteria, two reviewers independently screened literature, extracted data, and assessed the methodologically quality of the included studies. Then, meta-analysis was performed using RevMan 5.1 software. Results 10 RCTs involving 3 553 ACS patients were finally included. The results of meta-analysis showed that: compared with intravenous administration, intracoronary GPIs administration decreased the major adverse cardiovascular event (MACE) (OR=0.54, 95%CI 0.34 to 0.85, P=0.008). The incidences of re-infarction (MI), revascularization (TVR) and heart failure were (OR=0.62, 95%CI 0.39 to 0.97, P=0.04), (OR=0.59, 95%CI 0.36 to 0.97, P=0.04), (OR=0.52, 95%CI 0.32 to 0.84, P=0.008), respectively. But for the mortality, there were no significant differences between the two groups (OR=0.81, 95%CI 0.58 to 1.14, P=0.23). Intravenous administration and intracoronary administration were alike in the incidences of mild/serious bleeding (mild: OR=0.94, 95%CI 0.75 to 1.19, P=0.63; serious: OR=1.18, 95%CI 0.76, 1.84, P=0.47). Conclusion Compared with routine GPIs regimen of intravenous bolus, intracoronary administration with initial dosage showed significant benefits in clinical outcomes in ACS patients undergoing PCI, which could not increase the incidence of bleeding.

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 assess the curative effect of percutem transilluminated with negative pressured on the potaried technique on the treatment of venous ulcer in lower extremity. Methods The clinical date of 300 cases involving 300 legs with venous ulcer in lower extremity, who underwent the percutum transilluminated negative pressured potaried technique using TRIVEXTM Ⅱ potaried system or the percutum transfixion surgical treatment from October 2005 to June 2009, were analyzed. Three hundred cases were randomly divided into potaried group and transfixion group. In potaried group, there were 190 cases involving 190 legs treated with TRIVEXTM Ⅱ potaried system. In transfixion group, 110 cases involving 110 legs treated with percutum transfixion. The clinical indexes of skin infection rate and skin necrosis rate, shrinkage rate of wound area and skin depigmentation rate, ulcer healing rate and ulcer recurrence rate were calculated to assess the clinical curative effect on day 5, day 20, day 120 and day 360 after operation respectively. Results The rates of skin infection and skin necrosis were significantly decreased in potaried group compared with transfixion group on day 5 after operation (P<0.05), the rates of shrinkage of wound area and skin depigmentation were significantly increased in potaried group compared with transfixion group on day 20 (P<0.05). The ulcer healing rate was not significantly different between the two groups on day 120 (Pgt;0.05). Ulcer recurrence rate was remarkably lower in potaried group than that in transfixion group on day 360 (P<0.05). Conclusion It can be concluded that percutem transilluminated with negatived pressured on the potaried technique with TRIVEXTM Ⅱ potaried system can efficiently promote the healing of venous ulcer in the lower extremity, and at the same time it has an ascendancy in lessening skin infection and skin reinjury.
