Abstract

Objective: To compare the effectiveness of a hysteroscopic niche resection versus no treatment in women with postmenstrual spotting and a uterine caesarean scar defect. Design: Multicentre randomised controlled trial. Setting: Eleven hospitals collaborating in a consortium for women's health research in the Netherlands. Population: Women reporting postmenstrual spotting after a caesarean section who had a niche with a residual myometrium of ≥3 mm, measured during sonohysterography. Methods: Women were randomly allocated to hysteroscopic niche resection or expectant management for 6 months. Main outcome measures: The primary outcome was the number of days of postmenstrual spotting 6 months after randomisation. Secondary outcomes were spotting at the end of menstruation, intermenstrual spotting, dysuria, sonographic niche measurements, surgical parameters, quality of [email protected], women's satisfaction, sexual function, and additional therapy. Outcomes were measured at 3 months and, except for niche measurements, also at 6 months after randomisation. Results: We randomised 52 women to hysteroscopic niche resection and 51 women to expectant management. The median number of days of postmenstrual spotting at baseline was 8 days in both groups. At 6 months after randomisation, the median number of days of postmenstrual spotting was 4 days (interquartile range, IQR 2–7 days) in the intervention group and 7 days (IQR 3–10 days) in the control group (P = 0.04); on a scale of 0–10, discomfort as a result of spotting had a median score of 2 (IQR 0–7) in the intervention group, compared with 7 (IQR 0–8) in the control group (P = 0.02). Conclusions: In women with a niche with a residual myometrium of ≥3 mm, hysteroscopic niche resection reduced postmenstrual spotting and spotting-related discomfort. Tweetable abstract: A hysteroscopic niche resection is an effective treatment to reduce niche-related spotting.
