Outpatient hysteroscopic removal of intrauterine devices in early pregnancy: feasibility and outcomes

Abstract

To describe our experience with outpatient hysteroscopy for removal of intrauterine devices (IUDs) in pregnant patients, along with the pregnancy-related outcomes. Retrospectively and prospectively collected data between January 2015 and April2021. Hysteroscopic outpatient clinic (See and Treat Clinic) at a university affiliated, tertiary medical center. Forty-one patients with an inadvertent but desired pregnancy up to 12 weeks + 6 days gestational age with an IUD in situ, with documented failed attempts of IUD removal. After ultrasonographic confirmation of IUD location, gestational age, and viability, a small-caliber hysteroscope was introduced via a vaginoscopic approach. The uterus was distended using 0.9% normal saline until a clear view was achieved. On visualization, the IUD was grasped by its strings, tail, or lateral arm using a semirigid hysteroscopic grasper. Oral antibiotic prophylaxis was prescribed in all cases. The primary outcome of interest was term delivery, from 37 weeks of gestation. Secondary outcomes included patient-reported tolerability and satisfaction, and procedure-related and pregnancy related complications. The procedure was completed successfully in all 41 patients. Thirty-three patients continued their pregnancies, resulting in 32 full-term singleton deliveries and 1 singleton preterm delivery at 33 + 4 weeks. Median gestational age at delivery was 39 weeks, with a median birthweight of 3,450 grams. Eight patients (19.5%) miscarried, 4 of these within a week of the procedure. In cases of desired pregnancy with an IUD, outpatient hysteroscopic removal of the IUD is a safe and effective management option. Broader uptake of outpatient hysteroscopy and development of hysteroscopic skills will allow more clinicians to offer patients this effective solution.
