PurposeThe purpose of this study was to examine the impact of robotic-assisted laparoscopic hysterectomy (RALH) compared with total abdominal hysterectomy by laparotomy (TAH) on vaginal cuff healing in early-stage endometrial carcinoma patients receiving adjuvant intravaginal brachytherapy (IVBT).Methods and materialsWe included 137 consecutive patients who underwent adjuvant IVBT without external beam radiation therapy or chemotherapy for stage I-II endometrial carcinoma. All patients underwent either RALH or TAH. Vaginal cuff healing status as assessed by inspection and palpation at initial evaluation by radiation oncology (VC1) was the primary outcome, with secondary outcomes including vaginal cuff healing status at first scheduled IVBT (VC2), time interval from hysterectomy to initiation of IVBT, and local recurrence.ResultsAmong 137 patients, 74 (54.0%) underwent RALH and 63 (46.0%) underwent TAH. There was no significant difference in mean time from hysterectomy to initial radiation oncology evaluation between RALH and TAH patients (approximately 30 days in both groups). RALH was the only covariate associated with protracted vaginal cuff healing time at both VC1 (P = .003) and VC2 (P = .038). There was a significantly increased mean interval between hysterectomy and start of IVBT for patients undergoing RALH from 47.7 to 55.0 days (P < .001). Vaginal cuff healing was more likely to contribute to delay in delivery of IVBT in RALH patients, whereas abdominal or other nonvaginal wound healing was more likely to contribute to delay in TAH patients. There were no vaginal cuff recurrences detected after 16 months median follow-up.ConclusionsRALH for early-stage endometrial carcinoma was associated with longer vaginal cuff healing time and a mean increase in interval from hysterectomy to IVBT of 1 week compared with TAH.
