This study was designed to compare three-dimensional (3D) laparoscopy and conventional two-dimensional (2D) laparoscopy in surgical performance and clinical assessment during laparoscopic radical hysterectomy with pelvic lymphadenectomy (LRHND) for treating early-stage cervical cancer. In this study, we included 67 consecutive patients underwent LRHND for treating early-stage cervical cancer by the experienced laparoscopic surgeons between August 2018 and December 2020. amongst these patients, 32 patients underwent 3D laparoscopy (2D group) and 35 patients underwent 2D laparoscopy (2D group). Demographic data, clinical and surgical parameters were obtained from each patient. An end-of-operation questionnaire was administered regarding subjective perception of 3D laparoscopy system. Patient characteristics, including age, BMI, FIGO stage, and histology, were comparable between the two groups. Compared with 2D imaging system, 3D system significantly shortened the operation time, especially bilateral lymph node dissection time. Blood loss was lower in 3D group compared with 2D group. There were no significant differences regarding pelvic nodes retrieved, incidence of complications, hospital stay, the recovery time of bowel, abdominal drainage fluid, hospitalization costs and visual symptoms. In addition, 3D system significantly improved depth perception and precision, and reduced surgical strain and eye strain for surgeon. No statistical difference was observed in visual symptoms and adverse events between the two groups. The surgeon was more willing to accept 3D laparoscopy. The 3D laparoscopy is safe, feasible and comfortable, with obvious advantage in depth perception, precision and surgical strain. It triggered no increase in the complications and adverse events.

3D 和 2D 腹腔镜比较：围手术期结果和临床评估的初步经验

本研究旨在比较三维（3D）腹腔镜和传统二维（2D）腹腔镜在腹腔镜根治性子宫切除术联合盆腔淋巴结切除术（LRHND）治疗早期宫颈癌期间的手术表现和临床评估。在这项研究中，我们纳入了2018年8月至2020年12月期间由经验丰富的腹腔镜外科医生连续接受LRHND治疗早期宫颈癌的67名患者。其中，32名患者接受了3D腹腔镜检查（2D组），35名患者接受了2D腹腔镜检查（2D组）。二维组）。从每位患者处获得人口统计数据、临床和手术参数。对 3D 腹腔镜系统的主观感受进行了手术结束问卷调查。两组患者的特征，包括年龄、BMI、FIGO 分期和组织学，具有可比性。与2D成像系统相比，3D系统显着缩短了手术时间，特别是双侧淋巴结清扫时间。与 2D 组相比，3D 组的失血量较低。盆腔淋巴结的取出、并发症的发生率、住院时间、肠道恢复时间、腹腔引流液、住院费用和视觉症状等方面均无显着差异。此外，3D系统显着提高了深度感知和精度，并减轻了外科医生的手术疲劳和眼睛疲劳。两组之间的视觉症状和不良事件没有观察到统计学差异。外科医生更愿意接受3D腹腔镜检查。 3D腹腔镜安全、可行、舒适，在深度感知、精准度和手术劳损方面具有明显优势。它没有引发并发症和不良事件的增加。
