全麻复合硬膜外在高龄患者腹腔镜直肠癌根治术中的应用

目的:研究全麻复合硬膜外在高龄患者腹腔镜直肠癌根治术中的应用效果。方法:选择60岁以上择期行腹腔镜直肠癌根治术患者60例,随机分为G组和GA组,每组各30例。G组患者为单纯全麻组,GA组患者为硬膜外复合全麻组。GA组患者在诱导前取L1~2硬膜外穿刺置管,予0.5%罗哌卡因5 ml,术中每小时追加5~7 ml。两组患者诱导方法相同:即,咪哒唑仑0.04 mg/kg、舒芬太尼0.3~0.4μg/kg、顺阿曲库铵0.15~0.20 mg/kg、依托咪酯0.2~0.3 mg/kg。监测并记录患者血压(BP),心率(HR),心电图(ECG),术中全麻药用量及术后患者苏醒情况。结果:GA组患者气腹后、拔管前BP、HR明显低于G组(P<0.05),且全麻药用量明显低于G组(P<0.05)。结论:全麻复合硬膜外应用于老年腹腔镜直肠癌手术较单纯全麻用药量减少,术中循环更加稳定,是腹腔镜直肠癌根治术比较安全可行的麻醉方法。     

腹腔镜胆囊切除术患者围术期多项血清应激状态相关指标变化观察

目的:分析腹腔镜胆囊切除术的临床疗效,分析其对血清应激指标的影响。方法:将160例来我院行胆囊切除术的患者随机分为两组,对照组和观察组各80例。对照组采用开腹胆囊切除术,观察组则采用腹腔镜胆囊切除术。比较两组间手术时间、术中出血量、肠功能恢复时间以及住院天数差异,比较治疗前后两组患者间血清应激相关指标皮质醇(COR)、去甲肾上腺素(NE)、促肾上腺皮质激素(ACTH)、多巴胺(DA)以及胰岛素(INS)、三碘甲状腺原氨酸(T3)、甲状腺素(T4)、促甲状腺激素释放激素(TSH)水平差异。结果:观察组患者手术时间、术中出血量、肠功能恢复时间以及住院天数均显著少于对照组(P<0.05)。血清COR、NE、ACTH、DA和INS、T3水平在围手术期均发生了显著变化,各项指标均在胆囊分离时就明显升高,术后24 h开始下降(P<0.05);术后观察组上述指标均显著低于对照组(P<0.05)。结论:腹腔镜胆囊切除术对机体应激反应影响小于开腹手术,更利于患者术后康复。     

腹腔镜胆囊切除术对胆道结石合并糖尿病患者肠屏障功能的影响

目的观察胆道结石合并糖尿病患者腹腔镜胆囊切除术(LC)后肠屏障功能的变化。方法将择期行LC的126例患者分为糖尿病组41例和非糖尿病组85例。术前及术后第1、3天,采用高效液相色谱法检测尿乳果糖与甘露醇比值(L/M),并采用酶联免疫吸附法(ELISA)检测尿脂肪酸结合蛋白(IFABP)及血清D-乳酸水平。结果2组患者均成功完成手术,无中转开放手术者。糖尿病组术后肛门排气时间长于非糖尿病组,差异有统计学意义(P<0.05)。糖尿病组术后第1、3天尿L/M、血清D-乳酸、尿IFABP均高于术前及非糖尿病组,差异均有统计学意义(P<0.05)。结论合并糖尿病的胆道结石患者行LC后会加重肠屏障功能障碍程度,术前控制好血糖水平或可降低肠道功能损伤的严重程度。

Is laparoscopic liver resection safe for intrahepatic cholangiocarcinoma? A meta-analysis

BackgroundThe use of laparoscopic liver resection for curative surgery of intrahepatic cholangiocarcinoma (ICC) is not well established. Herein, we perform a meta-analysis to compare the differences between laparoscopic liver resection (LLR) and open liver resection (OLR) for ICC.MethodsMultiple electronic databases were searched and 8 relevant studies containing 552 patients treated by LLR and 2320 treated by OLR were identified. The fixed effects and a random-effects model were used to perform a meta-analysis.ResultsCompared with OLR, LLR for ICC was associated with less blood transfusion (7.14% versus 17.11%; OR: 0.32; 95% CI 0.15 to 0.71; P < 0.05), higher R0 resection (85.63% versus 74.69%; OR: 1.48; 95% CI 1.13 to 1.95; P < 0.05), shorter length of stay (LOS) (SMD: −0.40; 95% CI -0.80 to 0.00; P = 0.05), less overall morbidities (20% versus 32.69%; OR: 0.50; 95% CI 0.33 to 0.78; P < 0.05), and less death due to tumor recurrence (22.39% versus 35.48%; OR: 0.50; 95% CI 0.29 to 0.86; P <0.05); but LLR was associated with smaller ICC, fewer major hepatectomies, less lymph node (LN) dissection rate, and inferior 5-year overall survival (OS) (P < 0.05). Duration of operation, blood loss, average LN retrieved, LN metastasis, major morbidities, mortality, tumor recurrence, 3-year OS and disease free survival (DFS), and 5-year DFS were comparable (P >0.05).ConclusionLLR for ICC is in the initial phase of exploration. More evidence is necessary to validate LLR for ICC.     

The learning curve of laparoscopic ablation of liver tumors: A technically demanding procedure requiring dedicated training

BackgroundLaparoscopic ablation (LA) of liver tumors is an increasingly performed procedure. However, LA is technically demanding, with inherent difficulties making LA more complex than percutaneous and open surgery ablations. This study aimed to characterize the learning curve (LC) of LAs.MethodsAll consecutive LAs of malignant liver tumors performed with curative intent by a single surgeon were identified from a prospective database. A risk-adjusted cumulative summative (RA-CUSUM) analysis was used for evaluating the LC of LAs. Incomplete ablation (IA) was the outcomes measure. Performance trends were analyzed using broken-line modeling.ResultsFrom June 2007 to February 2018, 241 lesions underwent LA during 151 procedures. RA-CUSUM analysis demonstrated an LC of 93 LAs (p < 0.001), with an IA rate decreasing from 12.9% to 4.7% (p = 0.027). Lesions in the posterosuperior segment and those in cirrhotic livers showed an LC of 34 and 45 tumor ablations, respectively (p=<0.001 each). Open ablations performed during the same period showed steady outcomes, indicating already acquired proficiency.ConclusionCompletion of a steep LC is needed to gain proficiency in LAs. Dedicated training should be warranted to novices to smooth the LC and decrease LA failures.
