Effect of pneumatic leg compression on post-induction hypotension in elderly patients undergoing robot-assisted laparoscopic prostatectomy: a double-blind randomised controlled trial

Post-induction hypotension is common and associated with postoperative complications. We hypothesised that pneumatic leg compression reduces post-induction hypotension in elderly patients undergoing robot-assisted laparoscopic prostatectomy. In this double-blind randomised study, patients were allocated randomly to the pneumatic leg compression group (n = 50) or control (n = 50). In the intervention group, pneumatic leg compression was initiated before induction of anaesthesia. In the control group, pneumatic leg compression was initiated 20 min after anaesthesia induction. The primary outcome was the incidence of post-induction hypotension in these groups. Post-induction hypotension was defined as systolic blood pressure < 90 mmHg during the first 20 min after induction. Haemodynamic variables and area under the curve of post-induction systolic blood pressure over time were assessed. Complications associated with pneumatic leg compression were recorded, including: peripheral neuropathy; compartment syndrome; extensive bullae beneath the leg sleeves; and pulmonary thromboembolism. The incidence of post-induction hypotension decreased in the pneumatic leg compression group compared with that in the control group; 5 (10%) vs. 29 (58%), respectively, p < 0.001. In the pneumatic leg compression group, the lowest systolic, diastolic and mean blood pressures 20 min after induction of anaesthesia were significantly greater than the control group. Pneumatic leg compression resulted in an increased area under the curve of systolic blood pressure in the first 20 min after induction, p = 0.001. There were no pneumatic leg compression-related complications. Pneumatic leg compression reduced post-induction hypotension in elderly patients undergoing robot-assisted laparoscopic prostatectomy, suggesting that it is an effective and safe intervention to prevent post-induction hypotension among elderly patients undergoing general anaesthesia.

经皮肾镜气压弹道超声碎石在肾结石中的效果

目的 B超引导经皮肾镜气压弹道超声联合碎石治疗肾结石的临床效果。方法选择2017年9月-2018年9月医院收治的肾结石患者82例,按照抽签法的要求将其平均分成对照组(41例:B超引导经皮肾镜气压弹道超声治疗)与试验组(41例:输尿管软镜治疗),分析手术时间、住院时间、出血量、结石清除率、结石的残留率。结果试验组的手术时间、住院时间、出血量。优于对照组,数据比较有差异性,P<0.05。对照组的结石清除率高于试验组、结石的残留率低于试验组,相互比较有差异性,P<0.05。结论在肾结石实际治疗期,使用输尿管软镜钬激光碎石治疗方式。     

输尿管软镜和经皮肾镜治疗嵌顿性输尿管上段结石的效果比较

目的探讨输尿管软镜和经皮肾镜治疗嵌顿性输尿管上段结石的临床效果。方法选取52例嵌顿性输尿管上段结石患者,随机分为两组各26例。A组予以经皮肾镜治疗,B组予以输尿管软镜治疗。比较两组的结石清除情况、住院时间、术后VAS评分,以及手术前后的IL-4、IL-6、IL-10水平。结果A组术后3 d、术后3个月的结石清除率均显著高于B组(P<0.05)。A组的住院时间显著长于B组,术后VAS评分显著高于B组(P<0.05)。两组术前的IL-4、IL-6、IL-10水平无显著性差异(P>0.05);术后1 d,两组的IL-4、IL-6、IL-10水平均较术前显著升高,且A组显著高于B组(P<0.05)。结论与经皮肾镜相比,输尿管软镜治疗嵌顿性输尿管上段结石的结石清除率较低,但对患者损伤小,术后疼痛轻,恢复快。     

Peroral cholangioscopy: Update on the state-of-the-art

Peroral cholangioscopy (POC) is an endoscopic procedure that allows direct intraductal visualization of the biliary tract. POC has emerged as a vital tool for indeterminate biliary stricture evaluation and treatment of difficult biliary stones. Over several generations of devices, POC has fulfilled additional clinical needs where other diagnostic or therapeutic modalities have been inadequate. With adverse event rates comparable to standard endoscopic retrograde cholangioscopy and unique technical attributes, the role of POC is likely to continue expand. In this frontiers article, we highlight the existing and growing clinical applications of POC as well as areas of ongoing research.

目的探讨后腹腔镜切开取石术（retroperitoneal laparoscopic lithotomy，RPLU）、输尿管软镜碎石清石术（lithotripsy with flexible ureteroscope，FURL）及经皮肾镜碎石清石术（percutaneous nephrolithotomy，PCNL）种不同方法治疗输尿管上段嵌顿性结石的疗效，以明确直径大于1.5 cm的输尿管上段嵌顿性结石的最佳处理方案。 方法回顾性分析159例输尿管上段嵌顿性结石，收集其术前术中资料，按术式不同分为RPLU组56例、FURL组55例、PCNL组48例。对手术时间、术后住院时间、结石清除率、术后并发症等数据进行统计学分析。 结果FURL组手术时间和术后住院时间明显短于RPLU组和PCNL组，差异均有统计学意义（P＜0.05）。RPLU组术后3 d和术后1个月的结石清除率（100%，100%）稍高于FURL组（90.9%，94.5%）和PCNL组（93.8%，93.8%），3组患者术后无严重并发症出现，差异均无统计学意义（P＞0.05）。 结论3种不同手术方法治疗嵌顿性输尿管上段结石均安全有效，FURL组手术时间及住院时间更短，患者术后恢复更快，更具有优势。     

Litoplastia coronaria en lesiones calcificadas: registro multicéntrico de la práctica clínica

Introduction and objectivesCoronary lithoplasty (CL) is a balloon-based technique used to treat calcified lesions. This study reports the initial experience of treatment of calcified lesions with CL in an unselected and high-risk population.MethodsThis was a prospective, multicenter registry, which included all consecutive cases with calcified coronary lesions that underwent CL between August, 2018 and August, 2019. Exclusion criteria consisted of a target lesion located in a small vessel (< 2.5 mm) and the presence of dissection prior to CL. Quantitative coronary angiography and intravascular ultrasound/optical coherence tomography analysis were completed by an independent central core laboratory.ResultsThis registry included 57 patients (66 lesions). The population was elderly (72.6 ± 9.4 years) with high proportions of patients with diabetes (56%), chronic kidney disease (35%), and multivessel disease (84%). All lesions were classified as type B/C. More than 75% of lesions were predilated with noncompliant/semicompliant balloons or cutting-balloon. Rotablator was used in 5 lesions (7.6%) prelithoplasty. On average, CL required 1.17 balloons delivering a mean of 60 pulses. Successful CL was achieved in 98%. In 13% of cases, lithoplasty balloon was broken during therapy. There were few procedural complications: 2 cases of significant dissections (none related to lithoplasty balloon rupture) were successfully treated with drug-eluting stent implantation. One patient experienced stent thrombosis 2 days after successfully undergoing target lesion revascularization.ConclusionsThis is a real-world multicenter registry, which supports the feasibility, safety, and short-term efficacy of PCI for calcified coronary lesions using CL in an unselected and high-risk population with promising results.
