ObjectiveTo summarize the various treatment methods for reducing jaundice in the elderly patients with malignant obstructive jaundice (MOJ), and provide reference for the treatment of elderly MOJ.MethodUsing “malignant obstructive jaundice” as the Chinese keyword and the English keyword, a computer search of the literatures on the treatment of elderly MOJ patients was conducted and reviewed.ResultsThe treatment methods of reducing jaundice in elderly MOJ included radical surgery, cholangiojejunostomy, endoscopic ultrasound-guided biliary drainage, endoscopic biliary stent implantation, percutaneous transhepatic biliary drainage and stent implantation. Radical surgery was the most effective, but it was traumatic and had many complications for elderly patients. Cholangiojejunostomy was effective and suitable for elderly patients who cannot tolerate major surgery. Endoscopic ultrasound-guided biliary drainage was less traumatic to elderly patients, but technical difficulty. Endoscopic biliary stent implantation was currently the first-line choice for the treatment of elderly patients with advanced MOJ. Percutaneous transhepatic biliary drainage and stent implantation were suitable for elderly and frail patients with high obstruction.ConclusionThe treatment of elderly MOJ needs to be individualized and regionalized, and appropriate treatment methods should be selected according to the patient’s condition and the medical level of the medical center.
ObjectiveTo compare the clinical efficacy of carotid endarterectomy (CEA) and carotid artery stenting (CAS) in the treatment of patients with carotid artery stenosis, and to provide a more abundant evidence-based medicine for the treatment of CEA and CAS in patients with carotid artery stenosis. MethodsForty patients with carotid artery stenosis were randomly divided into CEA group and CAS group based on the operative indication. Patients in CEA group were given carotid endarterectomy treatment and those in CAS group were given carotid artery stenting treatment. Then clinical efficacy of the two groups were observed and compared. ResultsIn terms of the occurring rate of perioperative complications, cardiovascular events in 3 months after operation, and some major end events such as stroke, death and so on, the comparative difference between the two groups was of no statistical significance (P > 0.05). Through the followed-up visits of 12 months, the comparative difference between the two groups was also of no statistical significance (P > 0.05) in terms of the occurring rate of carotid artery restenosis and disabling or fatal stroke. ConclusionsFor patients with severe extracranial carotid stenosis under indication of operation treatment, carotid endarterectomy and carotid artery stenting are of equivalent clinical efficacy, and both of them are of high security, although further study with large-amount and evidence-based medical data in long term from multiple centers is still in need.
ObjectiveTo compare the clinical outcomes of transcatheter aortic valve implantation (TAVI) in oncology and non-oncology patients with severe aortic stenosis (AS).MethodsA computer-based search in PubMed, The Cochrane Library, EMbase, CBM, CNKI and Wanfang databases from their date of inception to December 2021 was performed, together with reference screening, to identify eligible clinical trials. Two investigators screened the articles, extracted data, and evaluated quality independently. RevMan 5.3 and Stata 12.0 softwares were used for meta-analysis.ResultsThe selected 8 cohort studies contained 57 988 patients, including 12 335 cancer patients and 45 653 non-cancer patients. The results of meta-analysis showed that in patients with cancer, the 30-day mortality [OR=0.74, 95%CI (0.65, 0.84), I2=0%, P<0.000 01], stroke [OR=0.87, 95%CI (0.76, 0.99), I2=0%, P=0.04] and acute kidney injury [OR=0.81, 95%CI (0.76, 0.85), I2=49%, P<0.000 01] were lower than those in patients without cancer. The 1-year mortality [OR=1.46, 95%CI (1.15, 1.86), I2=62%, P=0.002] and late mortality [OR=1.51, 95%CI (1.24, 1.85), I2=61%, P<0.000 1] were higher in patients with cancer.ConclusionIt is effective and safe in cancer patients with severe AS undergoing TAVI. However, compared with patients without cancer, it is still high in long-term mortality, and further study of the role of TAVI in cancer patients with AS is necessary.
ObjectiveTo evaluate the clinical outcomes of sutureless aortic valve replacement (SU-AVR) and transcatheter aortic valve implantation (TAVI) for aortic valve disease. MethodsWe conducted a computer-based search of databases including CNKI, WanFang Data, VIP, CBM, PubMed, The Cochrane Library, EMbase and Web of Science from the inception of the databases to March 2024. Two reviewers independently screened articles, extracted data and used the Cochrane bias risk assessment tool to evaluate the quality of the included studies. Meta-analysis was performed using Stata 18 software. ResultsThe included 17 studies using propensity-matched analysis consisted of 6 630 patients, including 3 319 patients in the SU-AVR group and 3 311 patients in the TAVI group. The SU-AVR group had lower mortality than the TAVI group at 1-year ［RR=0.58, 95%CI(0.38, 0.87), P=0.009］, 2-year ［RR=0.61, 95%CI(0.43,0.85), P=0.004］ and 5-year ［RR=0.63, 95%CI(0.50,0.79), P=0.000］. The SU-AVR group had a significantly lower rate of new permanent pacemaker implantation (PPI) ［RR=0.75, 95%CI(0.58, 0.98), P=0.037］, moderate-to-severe paravalvular leak (PVL) ［RR=0.20, 95%CI（0.12, 0.32）, P=0.000］, myocardial infarction(MI)［RR=0.30, 95%CI (0.11,0.80), P=0.017］, more-than-mild residual aortic regurgitation (AR)［RR=0.29, 95%CI（0.17, 0.48）, P=0.000］. In addition, the SU-AVR group had a higher postoperative mean aortic gradient [SMD=0.39, 95%CI (0.17, 0.62), P=0.000］than the TAVI group. Conclusion The early and mid-term clinical outcomes of SU-AVR were superior compared to TAVI.
Objective To investigate the application value of spiral CT postprocessing technique in the airway stent implantation technology. Methods Twenty-three patients with malignant airway stenosis or malignant tracheoesophageal fistula who needed the treatment of airway stent implantation from May 2012 to April 2016 were collected, including 19 males and 4 females with an average age of (61.6±10.0) years. Bronchoscopy and spiral CT with three-dimensional airway reconstruction were proceeded for the same patients before and after stent implantation, and the relevant data about narrow airway was measured by volume rendering, multiplanar reformation (MPR) and CT virtual endoscopy (CTVE) in a variety of ways, to confirm the location and size of narrow airway and fistulas, the degree and length of airway stenosis, as well as the distal end of the situation, and evaluate the patency of airway, the position and shape of stents, adjacent airway and complications after stenting. The positive forecast outcomes of the two inspections wascompared. Results Airway stents were placed successfully according to the data from the spiral CT airway three-dimensional reconstruction. Thirty stents were implantated in the 23 patients, including 21 column-type stents, 3 L-type stents, and 6 Y-type stents. All stents stayed in situ, with patency and no deformation.The fistulas were closed and the airways were reopened. Symptoms of cough after eating and drinking and dyspnea were relieved. The positive rates of bronchoscopy and CT examination on diagnosis of airway stenosis were both 100% (23/23). Complications: MRP showed tumor growth leading to stenosis again in 3 patients, and CTVE displayed mucous congestion in 2 patients. Conclusions The technique of 64-layer spiral CT postprocessing technique can measure the relate data of airway stricture or fistulas as a kind of convenient, quick, accurate, and noninvasive method in patients with malignant airway stenosis or tracheoesophageal fistula who need the treatment of airway stenting. It is of high reference value both to airway stent implanting and postoperative observation, and is worthy of application.
