OBJECTIVE To investigate the incidence of male sexual dysfunction (SD) including erectile dysfunction (ErD) and ejaculatory dysfunction (EjD) after minimally invasive rectal cancer surgery. BACKGROUND Male SD significantly affects post-rectal cancer surgery quality of life (QOL). Current assessments using the International Index of Erectile Function-5 are unsuitable for patients with reduced postoperative sexual activity, because it assumes sexual intercourse. This study addresses this gap using the Erection Hardness Score (EHS) and custom ejaculatory questionnaires. METHODS This prospective multicenter open-label phase II trial enrolled 399 patients who underwent laparoscopic (Lap), robotic (Ro), or transanal (Ta) rectal cancer surgery. EHS and custom ejaculatory questionnaires assessed ErD, EjD, and potency impairment at 3, 6, and 12 months postoperatively. The rates were assessed in the full analysis set and compared between the Lap and Ro groups after propensity score matching. RESULTS At 12 months, the overall incidences of ErD and EjD were 34.7% and 29.8%, respectively. The Ro group showed a significantly lower EjD rate (25.0%) than the Lap group (40.9%), with no significant difference in ErD. Potency impairment was lower in the Ro group at 6 months (32.7% vs. 22.3%) and 12 months (29.0% vs. 17.8%) postoperatively. The Ta group showed relatively high ErD and EjD at 3 months, with some recovery at 12 months. CONCLUSIONS Minimally invasive rectal cancer surgery commonly results in ErD, EjD, and potency impairment. Robotic surgery provides lower EjD rates and less potency impairment. Comprehensive sexual function assessments are essential to inform patients and improve QOL outcomes.

腹腔镜、机器人和经肛门入路治疗直肠癌后男性性功能障碍的前瞻性多中心综合调查(LANDMARC 研究)。



目的 探讨微创直肠癌手术后男性性功能障碍 (SD) 的发生率,包括勃起功能障碍 (ErD) 和射精功能障碍 (EjD)。背景 男性 SD 显着影响直肠癌手术后的生活质量 (QOL)。目前使用国际勃起功能指数 5 的评估不适用于术后性活动减少的患者,因为它假设有。本研究使用勃起硬度评分 (EHS) 和定制射精问卷解决了这一差距。方法 这项前瞻性多中心开放标签 II 期试验招募了 399 例接受腹腔镜 (Lap) 、机器人 (Ro) 或经肛门 (Ta) 直肠癌手术的患者。EHS 和定制射精问卷评估了术后 3 、 6 和 12 个月的 ErD 、 EjD 和效力损害。在完整分析集中评估比率,并在倾向评分匹配后在 Lap 和 Ro 组之间进行比较。结果 12 个月时,ErD 和 EjD 的总发生率分别为 34.7% 和 29.8%。Ro 组的 EjD 率 (25.0%) 显著低于 Lap 组 (40.9%),ErD 无显著差异。Ro 组在术后 6 个月 (32.7% vs. 22.3%) 和 12 个月 (29.0% vs. 17.8%) 的效力损害较低。Ta 组在 3 个月时表现出相对较高的 ErD 和 EjD,在 12 个月时有所恢复。结论 微创直肠癌手术通常会导致 ErD 、 EjD 和效力受损。机器人手术提供较低的 EjD 率和较小的效力损害。全面的性功能评估对于告知患者和改善 QOL 结果至关重要。
