To compare surgical outcomes of patients with endometrial cancer who underwent robotic surgery across different BMI categories. A retrospective study including all consecutive patients with endometrial cancer who underwent robotic surgery at a tertiary cancer center between December 2007 and December 2022. The study analyzed outcome measures, including blood loss, surgical times, length of hospitalization, perioperative complications, and conversion rates with the Kruskal-Wallis test for BMI group differences and the Chi-squared test for associations between categorical variables. A total of 1329 patients with endometrial cancer were included in the study. Patients were stratified by BMI: <30.0 ( = 576; 43.3%), 30.0–39.9 ( = 449; 33.8%), and ≥ 40.0 ( = 304; 22.9%). There were no significant differences in post-anesthesia care unit (PACU) stay ( = 0.105) and hospital stay ( = 0.497) between the groups. The rate of post-op complications was similar across the groups, ranging from 8.0% to 9.5% ( = 0.761). The rate of conversion to laparotomy was also similar across the groups, ranging from 0.7% to 1.0% ( = 0.885). Women with a BMI ≥40.0 had a non-clinically relevant but greater median estimated blood loss (30 mL vs. 20 mL; < 0.001) and longer median operating room (OR) time (288 min vs. 270 min; < 0.001). Within the OR time, the median set-up time was longer for those with a higher BMI (58 min vs. 50 min; p < 0.001). However, skin-to-skin time (209 min vs. 203 min; = 0.202) and post-op time (14 min vs. 13 min; = 0.094) were comparable between groups. BMI does not affect the peri-operative outcome of patients undergoing robotic staging procedures for endometrial cancer.

体重指数对子宫内膜癌机器人手术结果的影响

比较不同 BMI 类别接受机器人手术的子宫内膜癌患者的手术结果。一项回顾性研究，包括 2007 年 12 月至 2022 年 12 月期间在三级癌症中心接受机器人手术的所有连续子宫内膜癌患者。该研究分析了结果指标，包括失血量、手术时间、住院时间、围手术期并发症和转化率用于 BMI 组差异的 Kruskal-Wallis 检验和用于分类变量之间关联的卡方检验。该研究总共纳入了 1329 名子宫内膜癌患者。患者按BMI分层：<30.0（= 576；43.3%）、30.0-39.9（= 449；33.8%）和≥ 40.0（= 304；22.9%）。各组之间麻醉后监护室 (PACU) 停留时间 (= 0.105) 和住院时间 (= 0.497) 没有显着差异。各组术后并发症发生率相似，范围为 8.0% 至 9.5% (= 0.761)。各组间转为剖腹手术的比率也相似，范围为 0.7% 至 1.0% (= 0.885)。BMI ≥ 40.0 的女性具有非临床相关性但中位估计失血量更大（30 mL 与 20 mL；< 0.001），且中位手术室 (OR) 时间更长（288 分钟与 270 分钟；< 0.001）。在 OR 时间内，BMI 较高的患者的中位准备时间较长（58 分钟与 50 分钟；p < 0.001）。然而，两组之间的皮肤接触时间（209 分钟 vs. 203 分钟；= 0.202）和术后时间（14 分钟 vs. 13 分钟；= 0.094）具有可比性。BMI 不会影响接受子宫内膜癌机器人分期手术的患者的围手术期结果。
