BACKGROUND: The Doppler is thought to be more comfortable and effective compared to the fetoscope for assessing the fetal heart rate (FHR) during labor. However, in a rural Tanzanian hospital, midwives who had easy access to both devices mostly used fetoscope. This study explored midwives' perception of factors influencing their preference for using either a Pinard fetoscope or a FreePlay wind-up Doppler for intermittent FHR monitoring. METHODS: Midwives who had worked for at least 6 months in the labor ward were recruited...

Fetoscopic laser coagulation of arterio-venous anastomoses (AVA) in a monochorionic placenta is the standard of care for twin-twin transfusion syndrome (TTTS), but is technically challenging and can lead to significant complications. Acquiring and maintaining the necessary surgical skills require consistent practice, a critical caseload, and time. Training on realistic surgical simulators can potentially shorten this steep learning curve and enables several proceduralists to acquire procedure-specific skills simultaneously...

INTRODUCTION: : Minimally invasive fetal therapeutic procedures reduce the morbidity and mortality in monochorionic (MC) twins and in fetuses with congenital diaphragmatic hernia (CDH). MC pregnancies share their blood systems due to communicating vessels over their single placenta and may develop specific complications: Twin-to-Twin transfusion syndrome (TTTS), Selective intrauterine growth restriction (sIUGR), Twin Anemia-Polycythemia Sequence (TAPS), Twin Reverse Arterial Perfusion Syndrome (TRAP) or anomalies in one...

INTRODUCTION: Lung hypoplasia and pulmonary arterial hypertension (PAH) in congenital diaphragmatic hernia (DH) lead to a high perinatal mortality. Although sustained fetoscopic tracheal occlusion (TO) improves lung development, a major side effect is abnormal pneumocyte differentiation. This study evaluated the potential ability of intra-tracheal retinoic acid (RA) administration to reduce adverse effects of sustained TO in a rabbit model of DH. METHODS: A left diaphragmatic defect was created on d23 in time-dated pregnant rabbits...

Monochorionic twin pregnancies are at risk of unique complications due to placental sharing and vascular connections between placental territories assigned for each twin. Twin anemia-polycythemia sequence (TAPS) is an infrequent but potentially dangerous complication of abnormal placental vascular connections. TAPS occurs due to very-small-caliber (< 1 mm) abnormal placental vascular connections which lead to chronic anemia in the donor twin and polycythemia in the recipient twin. TAPS may occur spontaneously or following fetoscopic laser photocoagulation of communicating placental vessels for twin-twin transfusion syndrome...

PURPOSE OF REVIEW: To examine updates in fetal spina bifida surgical repair, as well as promising results emerging from translational medicine. RECENT FINDINGS: Although the Management of Myelomeningocele Study sponsored by the National Institutes of Health helped establish the neonatal benefits of prenatal spina bifida repair via uterine hysterotomy, also known as 'open' fetal surgery, fetoscopic approaches may yield better maternal and obstetric outcomes. SUMMARY: Spina bifida is a severe congenital malformation associated with significant neonatal and childhood morbidity and mortality...

The most effective treatment for twin-to-twin transfusion syndrome is laser photocoagulation of the shared vascular anastomoses in the placenta. Vascular connections are extremely challenging to locate due to their caliber and the reduced field-of-view of the fetoscope. Therefore, mosaicking techniques are beneficial to expand the scene, facilitate navigation, and allow vessel photocoagulation decision-making. Local vision-based mosaicking algorithms inherently drift over time due to the use of pairwise transformations...

Congenital diaphragmatic hernia is rare birth defect, which can be easily corrected after birth. The main problem is that herniation of viscera during fetal development impairs lung development, leading to a 30 % mortality and significant morbidity. In isolated cases the outcome can be accurately predicted prenatally by medical imaging. Cases with a poor prognosis can be treated before birth; clinically this is by fetoscopic endoluminal tracheal occlusion. Obstruction of the airways triggers lung growth. This procedure and is currently being evaluated in a global clinical trial for left sided cases; right sided cases with poor prognosis are offered the procedure clinically...

OBJECTIVE: The aim of this study was to assess the feasibility and the effectiveness of a fetoscopic myelomeningocele (MMC) repair with a running single suture using a 2-port access in the sheep model. METHODS: Eighteen fetuses underwent surgical creation of a MMC defect at day 75. Fetuses were then randomized into 3 groups. Four fetuses remained untreated (control group). In the other 14 fetuses, a prenatal repair was performed at day 90: 7 fetuses had an open repair (oMMC), and 7 fetuses had a fetoscopic repair (fMMC) using a single-layer running suture through a 2-port access...

The aim of this study was to review fetoscopic laser photocoagulation (FLP), which ablates placental vascular anastomoses to treat twin-twin transfusion syndrome (TTTS). A review of studies reporting on the procedures, outcomes, complications and nonconventional applications of FLP for TTTS was conducted. FLP has been established as the primary treatment for monochorionic twin pregnancy associated with TTTS at 16-26 weeks. FLP is the only therapy that directly addresses the underlying pathophysiology. The recent technique modification of FLP, referred to as the 'Solomon technique', induces selective coagulation to connect the anastomoses ablation sites and has been introduced to reduce residual anastomoses...

Congenital diaphragmatic hernia (CDH) is a birth defect characterized by failed closure of the diaphragm, allowing abdominal viscera to herniate into the thoracic cavity and subsequently impair pulmonary and vascular development. Despite improving standardized postnatal management, there remains a population of severe CDH for whom postnatal care falls short. In these severe cases, antenatal surgical intervention (fetoscopic endoluminal tracheal occlusion [FETO]) may improve survival; however, FETO increases the risk of preterm delivery, is not widely offered, and still fails in half of cases...

OBJECTIVE: We have previously described our percutaneous fetoscopic technique for the treatment of open spina bifida (OSB). However, approximately 20-30% of OSB defects are too large to allow primary skin closure. We hereby describe a modification of our standard technique using a bilaminar skin substitute to allow closure of such large spinal defects. The aim of this study was to report our clinical experience with the use of a bilaminar skin substitute and a percutaneous fetoscopic technique for the prenatal closure of large spina bifida defects...

OBJECTIVE: To compare outcomes between 2 umbilical cord occlusion (UCO) methods: radiofrequency ablation (RFA) versus fetoscopic-guided laser photocoagulation. METHODS: Retrospective study of all monochorionic diamniotic multiple gestations that underwent UCO with RFA (preferred after 2014) or laser (preferred before 2014). In bivariate analysis, patients treated with RFA were compared with laser. Risk factors for intrauterine fetal demise (IUFD) and 30-day survival of the co-twin were identified, and multiple logistic models were fitted to examine whether the UCO method was associated with these outcomes...

BACKGROUND: Fetoscopic meningomyelocele repair in a gas-filled uterus is a new technique performed in very few centers. There are few opportunities as well as ethical prohibitions on the initial development and subsequent refinement of innovative fetal surgery techniques in humans, and using an animal model is both very expensive and logistically difficult. METHOD: We developed a low-fidelity endoscopic fetal surgery simulation using a plastic doll and pieces of chicken breast to simulate a fetal meningomyelocele, and a polyurethane ball to simulate a gas-filled uterus, along with a standard endoscopy system and instruments...

Congenital diaphragmatic hernia is surgically correctable, yet the poor lung development determines mortality and morbidity. In isolated cases the outcome may be predicted prenatally by medical imaging. Cases with a poor prognosis could be treated before birth. However, prenatal modulation of lung development remains experimental. Fetoscopic endoluminal tracheal occlusion triggers lung growth and is currently being evaluated in a global clinical trial. Prenatal transplacental sildenafil administration may in due course be a therapeutic approach, reducing the occurrence of persistent pulmonary hypertension, either alone or in combination with fetal surgery...
