Current opinion on large-scale prospective myomectomy databases toward evidence-based preconception and antenatal counselling utilising a standardised myomectomy operation note.

Background: No large-scale databases exist of pregnancy outcomes and rate of uterine rupture for women after myomectomy, resulting in inconsistent antenatal counselling and decision-making regarding mode and timing of delivery. Standardising information collected at myomectomy may facilitate data collection, informing prenatal/ antenatal counselling.

Objectives: To determine clinician opinions regarding standardisation of myomectomy operation notes to allow comprehensive data input into a prospective database of pregnancy outcomes, toward an evidence-based approach to decision making regarding timing and mode of delivery in subsequent pregnancies.

Materials and methods: A google forms survey was emailed to all consultant (attending-level) obstetricians and gynaecologists across 25 hospitals in London, Kent, Surrey, and Sussex (UK) between March and May 2022. To enhance response rates, two further email reminders were sent alongside in-person reminders from selected local unit representatives.

Main outcome measures: Senior clinician opinion for characteristics necessary to collect at time of surgery to develop a widescale database of post myomectomy pregnancy outcomes.

Results: 209/475 (44%) responses received; 95% (198/209) agreed with standardising operation notes. Criteria selected for inclusion included cavity breach (98%, 194/198), location (98%, 194/198), number of fibroids removed (93%, 185/198) and number of uterine incisions (96%, 190/198).

Conclusions: Gynaecologists support standardising myomectomy operation notes to inform the development of prospective large-scale databases of pregnancy outcomes after myomectomy.

What is new?: Acquisition of clinician opinions on the development and content of a standardised myomectomy operation note to aid the development of a pregnancy-outcome database for women after myomectomy.
