AIM: We investigated the effects of uterine cavity lavage using hypochlorous acid water (HClO) on preventing postoperative intrauterine infection after microwave endometrial ablation (MEA).
METHODS: Four hundred and eleven consecutive patients were enrolled in this study. The patients were divided into two groups: 214 cases in 2014-2016 with disinfection using povidone-iodine antiseptic solution alone (group A) and 197 cases in 2017-2019 with additional intrauterine douche using HClO (group B). HClO was used at a concentration of 200 ppm of residual chlorine. One gram of Ceftriaxone Sodium Hydrate was administered by drip infusion during MEA in both groups. Oral antibiotics were administered after MEA only in group A but not in group B.
RESULTS: Mean patient age (mean ± SD; years old) was 44.5 ± 4.6 in group A and 44.8 ± 5.4 in group B, and mean operation time (min) was 30.4 ± 19.1 in group A and 34.4 ± 22.6 in group B, respectively. Neither were significantly different between groups. The combined ablation techniques i.e. transcervical microwave myolysis and transcervical microwave adenomyolysis did not increase frequency of infection. Postoperative intrauterine infection cases in group B (8 cases) were significantly lower than those in group A (28 cases) (Chi-square test, P = 0.001). Hysterectomy was performed in three severe intrauterine infection cases in group A, but no cases of severe intrauterine infection was found in group B. No adverse effect of HClO was seen.
CONCLUSION: Intrauterine douche using HClO decreases postoperative intrauterine infection after MEA.
