A novel intrauterine estrogen-releasing system for preventing the postoperative recurrence of intrauterine adhesion: a multicenter randomized controlled study.
Trial report in BMC medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04972032 (Prevention of Postoperative Adhesion Recurrence by Estrogen-intrauterine Stent System), which is not on this map. Cited by 14 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundTranscervical resection of adhesions (TCRA) is the standard treatment for intrauterine adhesion (IUA). Previous studies have shown that postoperative oral estrogen or an intrauterine physical barrier could reduce the recurrence of IUA by promoting the proliferation of the endometrium or inhibiting the reformation of adhesions. Our team designed an intrauterine stent that can release estrogen within the uterine cavity slowly. In this study, we aimed to investigate the efficacy and safety of the estrogen-releasing intrauterine system in preventing the recurrence of moderate to severe IUA.
methodsThis was a multicenter prospective randomized controlled 2-arm parallel trial that included patients who were diagnosed with moderate to severe IUA and who received TCRA. A total of 250 patients were randomly assigned, at a 1:1 ratio, to receive the intrauterine estrogen-releasing system or a Foley catheter balloon combined with oral estrogen therapy after surgery. The primary outcome was the rate of adhesion reduction in the two groups. The secondary outcomes included endometrial thickness at the ovulation period, menstrual improvement rates, and other reported adverse events during follow-up.
resultsThe average daily drug release amount for all the tested stents was 0.21 mg/day. At 60 days postoperatively, the rate of adhesion reduction was significantly greater in the experimental group than in the control group (93.33% vs. 58.56%, p < 0.001). The endometrium of the experimental group was thicker than that of the control group (p < 0.001). Consistently, the rate of improvement in menstruation was greater in the experimental group than in the control group (p = 0.010). No grade 3-4 adverse events were found in the two groups during the 1-year follow-up.
conclusionsIn the cohort of patients with moderate to severe IUA, the intrauterine estrogen-releasing system was more effective at reducing adhesion than traditional oral estrogen combined with an intrauterine Foley catheter after TCRA. This novel intrauterine system provides a new option for the management of IUA after surgery.
