UNASSIGNED: A retrospective analysis was performed on a consecutive series of 76 patients who underwent RARH from July 2014 to March 2018. The operation time was evaluated using the cumulative sum (CUSUM) method to analyze the LC. The patients were categorized into two groups based on the LC: Phase I and Phase II. Statistical methods were used to compare clinicopathological data on intraoperative and perioperative outcomes at different stages of the study.
UNASSIGNED: The peak point of the LC was observed in the 27th case. Using the CUSUM method, we divide the LC into two stages. Stage 1 (initial learning stage): Cases 1-27 and Stage 2 (proficiency phase): Cases 28-76. There were no obvious distinctions between the two patients\' essential characteristics (age, sex, body mass index, clinical stage, and ASA score). The mean operation time of each group is 187.37 ± 45.56 min and 161.1 ± 37.74 min (P = 0.009), respectively. The intraoperative blood loss of each group is 170.4 ± 217.2 ml and 95.7 ± 72.8 ml (P = 0.031), respectively.
UNASSIGNED: Based on the LC with CUSUM analysis, the data suggest that the learning phase of RARH was achieved after 27 cases. The operation time and the intraoperative blood loss decrease with more cases performed.
■对2014年7月至2018年3月接受RARH的连续76例患者进行回顾性分析。使用累积和(CUSUM)方法评估手术时间以分析LC。根据LC将患者分为两组:I期和II期。采用统计学方法比较研究不同阶段术中和围手术期结局的临床病理资料。
■在第27种情况下观察到LC的峰点。使用CUSUM方法,我们将LC分为两个阶段。阶段1(初始学习阶段):案例1-27和阶段2(熟练阶段):案例28-76。两名患者的基本特征(年龄,性别,身体质量指数,临床分期,和ASA评分)。两组平均手术时间分别为187.37±45.56min和161.1±37.74min(P=0.009),分别。各组术中出血量分别为170.4±217.2ml和95.7±72.8ml(P=0.031),分别。
■基于具有CUSUM分析的LC,数据表明,RARH的学习期在27例后达到.随着病例的增加,手术时间和术中出血量减少。
