胸腔镜根治术对老年食管癌患者术后肺部感染与呼吸功能及炎症因子的影响

目的探讨胸腔镜根治术对老年食管癌患者术后肺部感染与呼吸功能及炎症因子的影响。方法选择100例行手术治疗的食管癌患者的临床资料进行回顾性分析,根据手术方法分为胸腔镜组60例与开胸组40例。比较2组术后肺功能、外周炎症因子水平以及肺部感染发生率。结果(1)2组术后24 h外周血炎症因子IL-6、IL-8、IL-10以及TNF-α均显著升高(P<0.05),但开胸组显著高于胸腔镜组(P<0.05);术后1周,2组外周血炎症因子水平均显著下降,2组间比较差异无统计学意义(P>0.05)。(2)术后1个月,开胸组患者FEV1、FEV1/FVC FVC均显著低于胸腔镜组,差异有统计学意义(P<0.05)。(3)术后3天开胸组CRP水平、WBC水平、体温以及呼吸频率均显著高于胸腔镜组,差异有统计学意义(P<0.05)。(4)胸腔镜组术后无肺部感染,开胸组有4例(10.0%)发生肺部感染,2组比较差异有统计学意义(P<0.05)。结论与传统开胸手术比较,胸腔镜食管癌根治术对老年患者呼吸功能、外周血炎症因子的影响相对较小,术后患者肺部感染发生率更低。     

Exploring the path less traveled: Distal radial access for diagnostic and interventional neuroradiology procedures

BackgroundRecently there is a trend for radial first which advocates radial artery access as the first choice to perform diagnostic and interventional neurovascular procedures. Although safer than the conventional common femoral artery access, it is associated with a high rate of radial artery occlusion. Distal radial artery access is recently proposed to avoid this complication. This study aims to assess the feasibility and safety of distal radial artery access across a wide range of interventional neurovascular procedures.Materials and methodsAll Interventional neurovascular cases attempted via distal radial artery access from September 2019 till March 2021 were included in the study. Data regarding patient demographics, distal radial artery diameter, access site cannulation, size of the sheath, procedural details including success rate and complications were collected.ResultsDuring the study period, 102 patients underwent 114 procedures via the distal radial artery approach. The mean age of patients was 41.9 ± 15.2 years. Overall procedure success rate via DRA was 94.7% (108/114). 72 diagnostic cerebral angiograms and 36 interventional procedures were successfully completed while six procedures required switching to alternate access.ConclusionDistal radial artery access is a safe and feasible option for diagnostic cerebral angiography and a wide range of neurovascular procedures.     

Incidence and risk factors for Chyle leak after pancreatic surgery for cancer: A comprehensive systematic review

BackgroundChyle leak (CL) is a clinically relevant complication after pancreatectomy. Its incidence and the associated risk factors are ill defined, and various treatments options have been described. There is no consensus, however, regarding optimal management. The present study aims to systematically review the literature on CL after pancreatectomy.MethodsA systematic review from PubMed, Scopus and Embase database was performed. Studies using a clear definition for CL and published from January 2000 to January 2021 were included. The PRISMA guidelines were followed during all stages of this systematic review. The MINORS score was used to assess methodological quality.ResultsLiterature search found 361 reports, 99 of which were duplicates. The titles and abstracts of 262 articles were finally screened. The references from the remaining 181 articles were manually assessed. After the exclusions, 43 articles were thoroughly assessed. A total of 23 articles were ultimately included for this review. The number of patients varied from 54 to 3532. Incidence of post pancreatectomy CL varied from 1.3% to 22.1%. Main risk factors were the extent of the surgery and early oral or enteral feeding. CL dried up spontaneously or after conservative management within 14 days in 53% to 100% of the cases.ConclusionsThe extent of surgery is the most common predictor of risk of CL. Conservative treatment has been shown to be effective in most cases and can be considered the treatment of choice. We propose a management algorithm based on the current available evidence.     

超声引导下腰方肌阻滞联合丙泊酚麻醉在腹腔镜结直肠癌根治术中的应用

目的:研究超声引导下腰方肌阻滞联合丙泊酚麻醉在腹腔镜结直肠癌根治术中的应用价值。方法:选取90例择期进行腹腔镜结直肠癌根治术患者作为研究对象，随机分为观察组和对照组，各45例。对照组采用传统腰麻联合丙泊酚麻醉，观察组采用超声引导下腰方肌阻滞联合丙泊酚麻醉，比较两组患者术中（麻醉后5、15、30、60 min）收缩压（SBP）、舒张压（DBP）、心率（HR）和术后不同时间段的疼痛评分（VAS评分），以及加用镇痛药情况和肠道恢复排气时间和术后48 h内不良反应发生情况。结果:两组患者SBP、DBP、HR组间、不同时间点及交互差异均有统计学意义（P<0.05），且观察组麻醉后上述指标波动较对照组小（P<0.05）；麻醉前，两组患者皮质醇、肾上腺素水平无显著差异（P>0.05），麻醉后各时间点观察组患者上述指标水平均显著低于对照组（P<0.05）；两组患者VAS评分组间、不同时间点及交互差异均有统计学意义（P<0.05），且观察组术后各时间点VAS评分均显著低于对照组（P<0.05）；观察组不良反应发生率显著低于对照组（8.89% vs 24.44%, P<0.05）；观察组患者加用镇痛药的人数、剂量和肠道恢复排气时间均显著少于对照组（P<0.05）。结论:超声引导下腰方肌阻滞联合丙泊酚麻醉在腹腔镜结直肠癌手术中具有良好、稳定的麻醉效果，可有效缓解患者疼痛，减少术后不良反应发生。
