Peri-operative morbidity and fertility outcome after repeat abdominal myomectomy for large fibroid uterus

This was a retrospective cohort study evaluating peri-operative morbidity of 66 women who underwent repeat abdominal myomectomy compared with 200 women who had primary myomectomy in the same period, matched for age and uterine size. We report the reproductive outcome of women seeking fertility after repeat myomectomy. More pre-operative GnRH analogues were used and midline abdominal skin incision performed in the repeat myomectomy group. The likelihood of major complication was three times higher in the repeat abdominal myomectomy group (OR 3.0, 95% CI 1.67-5.5, p < .001). There was a significantly longer mean hospital stay (p < .01), higher incidence of bleeding (p < .01) and urinary or wound infection (p < .01) in the repeat abdominal myomectomy group. Of the 47 women who had repeat myomectomy for fertility reasons, six women conceived and two live birth at term (4%). Our study highlights the significant peri-operative morbidity and poor subsequent live birth rate associated with repeat abdominal myomectomy.Impact statementWhat is already known on this subject? Repeat abdominal myomectomy is a major surgical procedure with significant morbidity. However, abdominal myomectomy for large fibroid uterus remains the preferred treatment method for women who wish to preserve fertility. Sufficient evidence related to the peri-operative morbidity and fertility outcome after repeat abdominal myomectomy is lacking.What do the results of this study add? This is the largest study reporting peri-operative morbidity and pregnancy outcome following repeat abdominal myomectomy. Our results highlight the three times increased risk of major complications associated with repeat abdominal myomectomy compared to primary myomectomy with the poor subsequent live birth rate.What are the implications of these findings for clinical practice and/or further research? Our study complements the sparse existing data on the outcome of repeat abdominal myomectomy and underscore the potentially significant peri-operative morbidity and poor subsequent live birth rate associated with the procedure. This information should be used in counselling women with fibroid recurrence after primary myomectomy before they embark on repeat surgery.
