Objective: To compare outcomes of fetoscopic spina bifida aperta repair (FSBAR) with the results of the open approach (OSBAR) as in the Management Of Myelomeningocele Study (MOMS). Methods: This was a systematic comparison of reports on FSBAR with data from the MOMS (n = 78). Inclusion criteria were studies of spina bifida aperta patients who underwent FSBAR and were followed for ≥12 months. Primary outcome was perinatal mortality. Secondary outcomes included operative, maternal, fetal, neonatal and infant outcomes. Results: Out of 16 reports, we included 5 from 2 centers. Due to bias and heterogeneity, analysis was restricted to two overlapping case series (n = 51 and 71). In those, FSBAR was technically different from OSBAR, had comparable perinatal mortality (7.8 vs. 2.6%, p = 0.212) and shunt rate at 12 months (45 vs. 40%, p = 0.619), longer operation time (223 vs. 105 min, p < 0.001), higher preterm prelabor membrane rupture rate (84 vs. 46%, p < 0.001), earlier gestational age at birth (32.9 vs. 34.1 weeks, p = 0.03), higher postnatal reoperation rate (28 vs. 2.56%, p < 0.001) and absence of uterine thinning or dehiscence (0 vs. 36%, p < 0.001). Functional outcomes were not available. Conclusion: FSBAR utilizes a different neurosurgical technique, takes longer to complete, induces more prematurity, requires additional postnatal procedures, yet has a comparable shunt rate and is not associated with uterine thinning or dehiscence. Long-term functional data are awaited.
