Introduction: Twin-to-twin transfusion syndrome affects monochorionic twin pregnancies and can result in fetal death. Endoscopic laser treatment remains a relatively infrequent procedure for this condition. This presents difficulties for maintaining proficiency and for training new personnel.
Objective: The dual mentoring program at our institution allows for continuous mentoring of new providers. We hypothesize that this approach stabilizes program proficiency despite the addition of new practitioners.
Methods: Query of the fetal treatment program database returned 146 cases of laser ablation between 2000 and 2019. Patient and pregnancy characteristics as well as operative time and outcomes were recorded. The learning curve-cumulative summation method and rolling averages were used to analyze outcomes.
Results: Overall survival was 69%, and survival of at least 1 twin was 89%. Mean operative time was 53.6 ± 20.9 min. Overall twin survival stabilized after the first 40 cases. Rolling averages for operative time decreased from 71 to 49 min for the most recent cases. These results were not affected by the introduction of new surgeons.
Conclusions: Creative mentoring can maintain stable overall program outcomes despite changes in team composition. This training approach may be applicable to other rare procedures in fetal surgery.
