Expert statements from the recordings in this collection.
Fetal Surgical Intervention for Myelomeningocele: Fetal Surgery 2012
Spina bifida affects approximately 1500 babies born per year in the US, about 30 per week or 5-6 per day.
Scott Adzik1:22:06
With standard postnatal care, approximately 14% of MMC patients die by age 5, mostly due to symptomatic brain stem compression from hindbrain herniation.
Scott Adzik1:23:20
About 85% of MMC patients require ventricular shunts with standard postnatal care, with approximately half developing shunt complications within one year.
Scott Adzik1:23:33
The two-hit hypothesis for MMC proposes that secondary damage occurs in utero from amniotic fluid, meconium, or hydrodynamic forces after the initial failure of neurulation.
Scott Adzik1:23:41
In fetal sheep models, mid-gestational spinal cord exposure leads to progressive neurologic injury that mimics human MMC, with paralysis and loss of sensation below the lesion level.
Scott Adzik1:26:09
In utero coverage of experimentally created MMC in fetal sheep rescues neurologic function at birth, with lambs able to stand, walk, and maintain continence.
Hindbrain herniation reverses after prenatal MMC repair because closing the defect prevents CSF leak, reestablishing the pressure column in the spinal canal.
Scott Adzik1:30:15
In CHOP's pre-MOMS experience with 50 fetal MMC repairs, the shunt rate by one year was 40%, compared to 85% with postnatal repair.
Scott Adzik1:33:10
Two-thirds of prenatally repaired MMC patients showed motor function two or more levels better than the anatomic lesion level.
Scott Adzik1:33:41
The MOMS trial was stopped early on December 7, 2010 by the Data Safety Monitoring Board due to demonstrated efficacy of prenatal surgery.
Scott Adzik1:42:18
In the MOMS trial, shunts were placed in 40% of the prenatal surgery group compared to 82% of the postnatal surgery group.
Scott Adzik1:42:55
At 30 months, 42% of babies in the prenatal surgery group could walk independently versus only 21% in the postnatal surgery group.
Scott Adzik1:43:31
Mean gestational age at delivery was 34 weeks in the prenatal surgery group versus 37 weeks in the postnatal group, with 13% of prenatal cases delivered before 30 weeks.
Scott Adzik1:44:57
At the time of delivery in the MOMS trial, the hysterotomy site was intact in about two-thirds of cases, very thin in one-quarter, with dehiscence in 9% and complete dehiscence in one case.
Scott Adzik1:44:32
Since the end of the MOMS trial, CHOP has had 359 referrals, with 202 evaluated on-site, but only 60 (30%) underwent fetal surgery.
Scott Adzik1:47:57
Fetal MRI is mandatory for preoperative evaluation because ultrasound alone can incorrectly identify hindbrain herniation; in 9 cases with absent hindbrain herniation on MRI, ultrasound showed positive or equivocal findings.
Scott Adzik1:49:07
Fetoscopic MMC repair using 3 or more ports leads to membrane fixation and tearing with uterine growth, resulting in premature birth 3-6 weeks after surgery and delivery before 30 weeks as a rule.
Scott Adzik1:49:47
Compared to open fetal MMC repair, fetoscopic repair has higher rates of fetal death, premature rupture of membranes, chorioamnionitis, oligohydramnios, premature delivery, and persistent hindbrain herniation.
Scott Adzik1:50:06
There have been three maternal deaths associated with open fetal surgery for MMC in South America (one in Colombia, two in Argentina).
Host summaryTodd Ponsky summarizes what Dr. Scott Adzik said — not the host's own clinical position2:12:16
In the US experience with open fetal surgery for MMC, there have been no maternal deaths and no serious maternal complications in recent years.
Todd Ponsky2:13:43
Longer operating room times and postoperative oligohydramnios correlate with increased risk for preterm birth in fetal MMC repair.
Scott Adzik1:46:17
A Washington University financial model using MOMS trial data showed that over $3 million would be saved for 100 babies treated prenatally versus postnatally.
In Europe, approximately one-third of mothers decline open fetal MMC surgery because it is an open procedure.
Todd Ponsky2:26:39
For proper neurosurgical repair of cystic MMC, it is essential to remove the cyst and excise tissues that don't belong, not simply cover the lesion—a step that may be missing in some fetoscopic approaches.
Todd Ponsky2:27:34
In the MOMS trial, 51% of prenatally repaired children met shunt criteria, but only 31 actually received shunts (approximately 65% of those meeting criteria), compared to 66 of 74 (89%) in the postnatal group.
Todd Ponsky2:30:23
The discrepancy between meeting shunt criteria and receiving shunts occurred because an independent neurosurgical review committee determined criteria, but individual neurosurgeons made placement decisions, and most discrepancies involved criterion 3 (head size/ventricle changes) without accompanying symptoms.
Using revised shunt criteria based on modified criterion 3, there is a close match between shunt criteria and actual shunt placement in both prenatal (46%) and postnatal (86%) groups.
Colorectal Quiz Episode 15: Bowel Management in Spinal Patients - Need for a UrologistPart 1
About 5% of colorectal work is surgical and the rest is bowel management.
MiraLax softens stool but does not provide a 'push' to expel it, which can leave the colon full of soft stool.
Christine Warner6:16
Senna and bisacodyl are the two medications that provide a 'kick' or push for stool expulsion; everything else is a stool softener.
