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.     

Retroperitoneal-first laparoscopic approach (Retlap)-assisted distal pancreatectomy with celiac axis resection (DP-CAR): A novel minimally invasive approach for achieving adequate dorsal surgical margin

BackgroundDistal pancreatectomy with celiac axis resection (DP-CAR) is a procedure to secure a surgical margin for a locally advanced pancreatic body cancer that invades the celiac axis. However, in patients with cancer close to the root of the celiac axis, obtaining adequate surgical margins can be difficult because the tumor obstructs the field of vision to the root of the celiac axis. Previously, we described the retroperitoneal-first laparoscopic approach (Retlap) to achieve both accurate evaluation of resectability for locally advanced pancreatic cancer requiring DP-CAR [1] and adequate surgical margin for laparoscopic distal pancreatectomy [2]. In this video, we introduce Retlap-assisted DP-CAR as a minimally invasive approach for performing an artery-first pancreatectomy [3, 4] and achieving sufficient dorsal surgical margin (Fig. 1).MethodsOur patient is a 67-year-old man with a 55 × 29-mm pancreatic body tumor after chemotherapy. Preoperative computed tomography revealed a tumor close to the root of the celiac axis. Because the area of tumor invasion on preoperative images was near the root of the celiac artery, Retlap-assisted DP-CAR was performed to determine whether the celiac axis can be secured and obtain an adequate dorsal surgical margin (Fig. 2).ResultsThe operative time and estimated blood loss was 715 min and 449 mL, respectively. In spite of the advanced tumor's location and size, R0 resection was achieved in a minimally invasive way.ConclusionRetlap-assisted DP-CAR is not only technically feasible and useful for achieving accurate evaluation of resectability but also facilitates obtaining an adequate surgical margin.     

单孔加一孔联合ERAS在高位直肠及乙状结肠癌中的应用

目的 探讨单孔加一孔腹腔镜手术联合 ERAS 治疗高位直肠及乙状结肠癌的近期疗效。方法 回顾性分析 2017 年 11 月至2018 年 10 月在福建省肿瘤医院胃肠肿瘤外科进行加速康复外科干预的 92 例高位直肠及乙状结肠癌患者资料，根 据手术方式的不同，分为单孔加一孔手术联合快速康复外科组39 例及常规腹腔镜手术联合ERAS 组 53 例，对比两组围术 期情况。结果 两组患者基线资料无明显统计学差异（P ＞ 0.05），且在手术时间、出血量、上下切缘、清扫淋巴结数量及 并发症方面无明显统计学差异（P ＞ 0.05）。但单孔加一孔手术联合ERAS 组较常规手术联合ERAS 组，总切口长度更短 [（6.7±1.1）cm 比（8.5±1.3）cm，P=0.000]，术后首次下床时间更早 [（22.2±5.2）h 比（27.1±7.9）h，P=0.001]，首次排便 时间更早[（70.2±19.8）h比（83.1±20.4）h，P=0.005]，术后第一天C反应蛋白值更低[（43.5±28.6）mg/L比（57.2±33.2） mg/L，P=0.038]，术后住院时间更短 [（7.0±1.7）d 比（8.1±2.1）d，P=0.010]，且术后 2~4 天疼痛评分更低（P ＜ 0.05）。 结论 经验丰富的腔镜医师采用单孔加一孔手术治疗高位直肠及乙状结肠癌并联合 ERAS 干预是安全可行的，且单孔加一孔 手术可减低操作难度，具有疼痛轻、术后恢复快等优势，值得临床推广。
