A study of unprotected left main intervention in the ACS population 2013–2018

ObjectivesOur objectives were to evaluate the outcomes of left main percutaneous coronary interventions in Acute Coronary Syndrome population.MethodsThis is a retrospective& observational study. Primary endpoint is a composite of death, stent thrombosis/MI, target lesion revascularization. Secondary endpoints include individual components of the primary events analyzed separately.ResultsSeventy five patients, two year follow – up data was analyzed. The primary event analysis showed that the Elective Double Stent (EDS) group had a higher primary events (36% vs. 14%, p value – 0.008, Hazard ratio – 0.76 (0.51–1.15, 95% CI), in secondary event analysis stent thrombosis (ST)/Myocardial infarction (MI) rates were higher in EDS group (8% Vs 36%, p Value – 0.008, Hazard ratio- 0.63(0.35–1.14, 95%CI), there is no difference in target lesion revascularization (TLR)and death rates in both the groups.ConclusionsThe provisional strategy is better than EDS in treatment of left main bifurcation lesions in the ACS population.     

胆总管结石内镜逆行胰胆管造影术后行胆道支架置入和鼻胆管引流并发症的比较

目的探讨胆总管结石患者采用内镜逆行胰胆管造影术（ERCP）取石后同期开展胆道支架置入术或开展经内镜鼻胆管引流术（ENBD），对于防范并发症的价值。 方法按照前瞻性研究原则，选择2017年4月至2019年1月新疆医科大学第一附属医院收治的338例胆总管结石患者，随机分为支架组（170例）与引流组（168例）。两组患者均行ERCP治疗，其中引流组术后同期开展ENBD，支架组患者术后开展胆道支架置入术，对比两组患者腹痛评分、并发症发生情况及预后。 结果两组患者术后均未合并严重出血、穿孔或病死，结石完全清除率差异无统计学意义。与支架组相比，引流组术中胰腺管插管次数，术后4 h血淀粉酶水平、高淀粉酶血症、急性胰腺炎以及并发症总发生率更高，差异有统计学意义（P<0.05），术后24、48、72 h不同时点腹痛测评分值居更高水平（P<0.05）。 结论对于胆总管结石行ERCP治疗的患者，术后予以ENBD、胆道支架置入术的结石完全清除效果对比无明显差异，但胆道支架置入术更能降低术后并发症风险、缓解腹痛症状，患者获益更多。     

Bypass Surgery or Stenting for Left Main Coronary Artery Disease in Patients With Diabetes

Background

The randomized EXCEL (Evaluation of XIENCE versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) trial reported a similar rate of the 3-year composite primary endpoint of death, myocardial infarction (MI), or stroke in patients with left main coronary artery disease (LMCAD) and site-assessed low or intermediate SYNTAX scores treated with percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). Whether these results are consistent in high-risk patients with diabetes, who have fared relatively better with CABG in most prior trials, is unknown.

Prognostic value of preoperative inflammatory markers in resectable biliary tract cancer – Validation and comparison of the Glasgow Prognostic Score and Modified Glasgow Prognostic Score in a Western cohort

IntroductionEstablished preoperative prognostic factors for risk stratification of patients with biliary tract cancer (BTC) are lacking. A prognostic value of the inflammation-based Glasgow Prognostic Score (GPS) and Modified Glasgow Prognostic Score (mGPS) in BTC has been indicated in several Eastern cohorts. We sought to validate and compare the prognostic value of the GPS and the mGPS for overall survival (OS), in a large Western cohort of patients with BTC.Material and methodsWe performed a retrospective single-center study for the period 2009 until 2017. 216 consecutive patients that underwent surgical exploration with a diagnosis of perihilar cholangiocarcinoma (PHCC), intrahepatic cholangiocarcinoma (IHCC), or gallbladder cancer (GBC) were assessed. GPS and mGPS were calculated where both CRP and albumin were measured pre-operatively (n = 168/216). Survival was analyzed by Kaplan-Meier estimate and uni-/multivariate Cox regression.ResultsGPS and mGPS were negatively associated with survival (p < 0.001/p < 0.001), and the association was significant in all three subgroups. GPS, but not the mGPS, identified an intermediate risk group: with GPS = 1 having better OS than GPS = 2 (p = 0.003), but worse OS than GPS = 0 (p = 0.008). In multivariate analyses of resected patients, GPS (p = 0.001) and mGPS (p = 0.03) remained significant predictors of survival, independent of postoperatively available risk factors.ConclusionsPreoperative GPS and mGPS are independent prognostic factors in BTC. The association to OS was shown in all patients undergoing exploration, in resected patients only, and in both cholangiocarcinoma and gallbladder cancer. Furthermore, GPS – which weights hypoalbuminemia higher – could identify an intermediate risk group.     

Clinical Utility of the Modified Snare Technique for Percutaneous Antegrade Removal of Double J Ureteral Stents

Although a snare is the commonly used device for antegrade double J (DJ) stent removal, there are some cases in which DJ stent removal using only a snare is particularly difficult. In the present study, an unfavorable positioning of the proximal DJ stent tip and tip embeddedness were significantly associated with a simple snare technique failure; thus, present the modified snare technique to overcome the simple snare technique failure. By applying these 2 techniques together, we can increase the overall technical success rate up to 97% (196/202). The modified snare technique is safe and effective in cases of simple snare technique failure.
