OBJECTIVE: To evaluate the efficacy of transcervical intralesional vasopressin injection to submucous myoma in hysteroscopic myomectomy from 2011 to 2014.
METHODS: This was a prospective, randomized, double-blind study in a single center. Forty premenopausal women with symptomatic submucous myoma requiring hysteroscopic myomectomy were randomized to transcervical intralesional vasopressin injection or placebo in a 4:4 ratio. The primary outcome was operative time. Secondary outcomes including fluid volumes, blood loss, and visual clarity were compared between the two groups.
RESULTS: The median duration for myomectomy was 19.9 minutes (range 3.1-54.2 minutes) in the vasopressin group compared with 29.0 minutes (range 8.0-60.9 minutes) in the placebo group, a nonsignificant difference (P=.14). There were significant reductions in the median volume of fluid used (4,200 mL [range 1,300-21,000 mL] compared with 9,800 mL (range 1,500-23,000 mL; P=.004) and fluid intravasation (0 mL [range 0-3,100] compared with 300 mL [range -150-3,150 mL; P=.029) in the vasopressin group. The median intraoperative blood loss was reduced (5 mL [range 1-50 mL] compared with 20 mL [range 1-150 mL; P=.002). The operative surgeon rated that 95% of the vasopressin group had "minimal" bleeding compared with 36.8% in the placebo group. The surgical field (visual analog scale [VAS] 9 [range 2-10] compared with 6 [range 2-10; P<.001]; 0=worst visual clarity, 10=best visual clarity) and the effluent fluid (VAS 1 [range 0-7] compared with 4 [range 0-8; P<.001]; 0=clear, 10=unclear) were statistically significantly clearer in the vasopressin group.
CONCLUSION: Transcervical intralesional vasopressin injection in hysteroscopic myomectomy did not reduce operative time but did reduce volume of inflow fluid, fluid intravasation, intraoperative blood loss, and improving visual clarity.
