The purpose of this study was to determine the learning curve of laparoscopic surgery for the treatment of early endometrial cancer and report the surgical outcomes.
Patients: Data were retrospectively extracted from the medical charts of patients who underwent laparoscopic surgery.
Laparoscopic surgery, including pelvic lymphadenectomy, was performed using the same technique and instruments for all patients.
The learning curve for the surgical technique, characterized by the operative time, number of lymph nodes removed, and volume of intra-operative blood loss, was analyzed.
Over the period of observation, 82 patients were enrolled. For analysis, cases were classified into four groups, based on their surgery date. Between-group comparisons identified a significant decrease in operative time and volume of blood loss between Groups 1 and 4 (P < 0.05). However, the number of lymph nodes removed, and the length of hospital stay were not influenced by learning.
The operative time and the amount of blood loss significantly decreased with an increase in the surgeon's experience but with no effect of learning on the number of lymph nodes removed and length of hospital stay.
本研究的目的是确定腹腔镜手术治疗早期子宫内膜癌的学习曲线，并报告手术结果。
患者：数据从接受腹腔镜手术患者的病历中回顾性提取。
所有患者均采用相同技术和器械进行包括盆腔淋巴结清扫术在内的腹腔镜手术。
分析了以手术时间、切除淋巴结数量和术中失血量为特征的手术技术学习曲线。
在观察期内，纳入了82例患者。为进行分析，根据手术日期将病例分为四组。组间比较发现，第1组和第4组之间的手术时间和失血量显著减少（P<0.05）。然而，切除淋巴结的数量和住院时间不受学习的影响。
随着外科医生经验的增加，手术时间和失血量显著减少，但学习对切除淋巴结的数量和住院时间没有影响。
