Towards a clinical consensus on the management of pregnancy and birth after laparoscopic and open myomectomy: A survey of obstetricians and gynaecologists.

OBJECTIVES: The primary aim was to assess if a clinical consensus regarding the management of pregnancy post myomectomy existed amongst consultant obstetricians and gynaecologists. Secondary objectives were to evaluate factors which influence the clinician's decision making in this group of women.

STUDY DESIGN: Electronic survey sent to all consultants working in the North Central and East London deanery, Kent Surrey and Sussex deanery and Imperial NHS Trust to assess opinions on mode of birth post myomectomy, intervals advised to pregnancy post myomectomy, factors influencing the management of delivery in the scarred uterus post myomectomy, opinions on induction of labour and questions relating to operative notes.

RESULTS: 209 consultant responses received between 07/03/2022-07/05/2022 (44% response rate); 77% (161/209) practicing obstetricians and gynaecologists, 10% (21/109) pure gynaecologists and 13% (27/209) pure obstetricians. The majority would support a vaginal birth after open myomectomy (75%) and laparoscopic myomectomy (79%). No consensus was found as to the optimal time interval between myomectomy and pregnancy. Higher frequency of performing myomectomy and a greater level of experience were significantly associated with a shorter interval to pregnancy advised. The most important operative factors influencing decision to support trial of labour post myomectomy were breach of uterine cavity; location of fibroids removed and number of incisions on the uterus. 77% believe women should be given a choice regarding mode of delivery post myomectomy in a similar way to previous LSCS. 82.8% would support enrolment of patients into a prospective trial to investigate delivery post myomectomy.

CONCLUSIONS: We present a comprehensive survey of clinician opinions on pregnancy post myomectomy demonstrating that the majority of consultant obstetricians and gynaecologists sampled would support vaginal birth post myomectomy; counselling patients in a similar way to VBAC; a standardised myomectomy operation note and enrolment of patients in a future prospective trial. Wide variation in opinion regarding interval to pregnancy post myomectomy has been highlighted. We believe this information will facilitate counselling discussions and empower women with subsequent pregnancies after myomectomy to make an informed decision on mode of birth post myomectomy.
