RESUMEN
INTRODUCTION: Spontaneous septostomy is a rare complication of multiple gestations. Related complications include cord entanglement and preterm delivery. Limited data exist to guide the management of these high-risk patients. The majority of spontaneous septostomy cases have been reported in monochorionic diamniotic twins. We present 2 cases of spontaneous septostomy occurring in a monochorionic/dichorionic hybrid twin gestation (chorionicity transitions from dichorionicity to monochorionicity within the placenta) and in a dichorionic triamniotic triplet gestation. CASE PRESENTATION: Case 1 was a monochorionic/dichorionic hybrid twin gestation with a septostomy complicated by fetal parts of one twin protruding into the co-twin's sac as well as symptomatic polyhydramnios. Fetal magnetic resonance imaging confirmed the septostomy. Case 2 was a dichorionic triamniotic triplet gestation with septostomy and cord entanglement. Both patients were managed akin to a pseudo-monoamniotic gestation with serial ultrasound surveillance and eventual inpatient admission for heightened fetal monitoring. Case 1 underwent elective scheduled cesarean delivery at 33 weeks, and case 2 underwent emergent cesarean delivery for fetal heart rate decelerations at 28 weeks. CONCLUSION: With a high degree of clinical suspicion, spontaneous septostomy can be diagnosed in uncommon settings such as hybrid twin gestations and higher order multiples. Management of such patients is individualized and may include a combination of heightened outpatient and inpatient surveillance.

INTRODUCTION: Ex-utero intrapartum treatment has been established as an option for fetal and perinatal surgeons to deliver patients with sacrococcygeal teratomas (SCTs) which are causing significant fetal distress and possible in-utero fetal demise. However, ex-utero intrapartum treatment procedures carry significant maternal risk and morbidity. Herein, we report an alternative technique of Cesarean section to immediate resection (CSIR) for managing high-risk SCTs. METHODS: A retrospective institutional review board-approved review was performed on all SCTs evaluated at our fetal center from May 2014 to September 2020. Demographics; prenatal imaging characteristics; prenatal interventions; and postnatal surgery data including operative time, estimated blood loss, pathology, and outcomes were collected. Outcomes of interest included surveillance serum alpha-fetoprotein levels, imaging surveillance, developmental milestones, and the presence or absence of constipation or fecal incontinence. RESULTS: A total of 20 patients with prenatal diagnosis of SCT were evaluated. Mothers who transferred their care to another institution after diagnosis were excluded from this study. Twelve neonates underwent standard postnatal resection. Three neonates underwent emergent CSIR for high output cardiac failure, fetal anemia, or concerns for in-utero hemorrhagic rupture. The median (interquartile range) operative time was 231.5 (113) minutes for the standard operative group versus 156 min in the CSIR group. We present three patients who underwent immediate resection after emergent Cesarean section. We report 100% survival for the three consecutive cases. CONCLUSIONS: CSIR is a safe and feasible approach for managing appropriately selected high-risk SCTs with signs of hydrops, fetal distress, or fetal anemia. Despite patient prematurity, we demonstrated 100% survival of three consecutive cases. We suggest that CSIR be considered an option in the management algorithm for high-risk SCTs.
RESUMEN
OBJECTIVE: To assess outcomes in twin-twin transfusion syndrome (TTTS) according to middle cerebral artery pulsatility index (MCA-PI) prior to fetoscopic laser photocoagulation (FLPC) surgery. METHODS: A retrospective cohort analysis of monochorionic-twin pregnancies complicated by TTTS who underwent FLPC at two fetal centers (2012-2021). The cohort was stratified according to abnormal MCA-PI of the donor twin, defined as below fifth centile for gestational age. RESULTS: Abnormal MCA-PI of the donor twin was detected in 46 (17.7%) cases compared to 213 (83.3%) controls with no such abnormality. The abnormal PI group presented with higher rates of sFGR (56.5% vs. 36.8% in controls, p = 0.014) and lower donor survival rates within 48 h after FLPC (73.9 vs. 86.8%, p = 0.029). Donor twin survival rates at the time of delivery and 30 days after birth were lower in the abnormal MCA-PI. Multivariate logistic regression analysis controlling for sFGR and MCA-PI Asunto(s)

RESUMEN
INTRODUCTION: Without fetal or perinatal intervention, congenital high airway obstruction syndrome (CHAOS) is a fatal anomaly. The ex utero intrapartum treatment (EXIT) procedure has been used to secure the fetal airway and minimize neonatal hypoxia but is associated with increased maternal morbidity. CASE PRESENTATION: A 16-year-old woman (gravida 1, para 0) was referred to our hospital at 31 weeks gestation with fetal anomalies, including echogenic lungs, tracheobronchial dilation, and flattened diaphragms. At 32 weeks, fetoscopic evaluation identified laryngeal stenosis, which was subsequently treated with balloon dilation and stent placement. The patient developed symptomatic and regular preterm contractions at postoperative day 7 with persistent sonographic signs of CHAOS, which prompted a repeat fetoscopy with confirmation of a patent fetal airway followed by Cesarean delivery under neuraxial anesthesia. Attempts to intubate through the tracheal stent were limited and resulted in removal of the stent. A neonatal airway was successfully established with rigid bronchoscopy. Direct laryngoscopy and bronchoscopy confirmed laryngeal stenosis with a small tracheoesophageal fistula immediately inferior to the laryngeal stenosis and significant tracheomalacia. A tracheostomy was then immediately performed for anticipated long-term airway and pulmonary management. The procedures were well tolerated by both mom and baby. The baby demonstrated spontaneous healing of the tracheoesophageal fistula by day of life 7 with discharge home with ventilator support at 3 months of life. CONCLUSION: Use of repeated fetoscopy in order to relieve fetal upper airway obstruction offers the potential to minimize neonatal hypoxia, while concurrently decreasing maternal morbidity by avoiding an EXIT procedure. Use of the tracheal stent in CHAOS requires further investigation. The long-term reconstruction and respiratory support of children with CHAOS remain challenging.

PURPOSE OF REVIEW: Fetal hydronephrosis secondary to congenital anomalies of the kidney and urinary tract (CAKUT) can adversely affect neonates in the postnatal period with long-term consequences. A prenatal diagnosis of CAKUT can have an early fetal intervention to minimize these consequences. This review aims to provide an overview of the possible fetal intervention with severe hydronephrosis. RECENT FINDINGS: Clinical course and outcomes of CAKUT are predicted based on biochemical markers and radiological findings. In spite of advancements and accurately diagnosing the severity of hydronephrosis, there are many controversies surround on selection of cases with antenatal hydronephrosis (ANH) that will benefit from fetal intervention. Despite better diagnosis and techniques fetal intervention is limited to mainly lower urinary tract obstruction patients to improve amniotic fluid volume and assist in lung development. SUMMARY: ANH can potentially detect the severity of congenital renal anomalies but unable to recognize a specific disease. A multidisciplinary approach is required to diagnose and properly stage cases of severe CAKUT and potential surgical intervention can be considered.

OBJECTIVE: To evaluate laparoscopy-assisted fetoscopic laser photocoagulation (FLPC) of placental anastomoses in the treatment of twin-to-twin-transfusion syndrome (TTTS). STUDY DESIGN: We performed a retrospective cohort study analyzing pregnancies complicated by TTTS who underwent FLPC in a single university-affiliated tertiary medical-center. Outcomes were compared between patients who received laparoscopy-assisted FLPC (study group) and patients who underwent the conventional FLPC technique (control group). Baseline characteristics, sonographic findings, procedure details, and neonatal outcomes were compared between groups. RESULTS: The cohort included 278 women with 31 in the study group and 247 in the control group. Sonographic parameters, including fetal biometry and TTTS stage, were comparable between study groups. Gestational age at delivery did not differ between the groups (29.22 ± 4.55 weeks in the study group vs. 30.62 ± 4.3 weeks in the control group, p = 0.09). There were no differences in neonatal survival rates at birth and at 30 days between both groups. A subanalysis comparing the laparoscopy-assisted group to only those patients with anterior placenta in the control group, showed a lower rate of incomplete Solomonization in the laparoscopy-assisted study group (3.4% vs. 33%, p = 0.01). CONCLUSION: Laparoscopy-assisted FLPC is a reasonable and safe option that may be offered in cases of FLPC where an anterior placenta restricts adequate surgical access.

BACKGROUND: Intercostal nerve cryoablation with the Nuss procedure has been shown to decrease opioid requirements and hospital length of stay; however, few studies have evaluated the impact on complications and hospital costs. METHODS: A retrospective cohort study was performed for all Nuss procedures at our institution from 2016 through 2020. Outcomes were compared across 4 pain modalities: cryoablation with standardized pain regimen (n = 98), patient-controlled analgesia (PCA; n = 96), epidural (n = 36), and PCA with peripheral nerve block (PNB; n = 35). Outcomes collected included length of stay, opioid use, variable direct costs, and postoperative complications. Univariate and multivariate hierarchical regression analysis was used to compare outcomes between the pain modalities. RESULTS: Cryoablation was associated with increased total hospital cost compared with PCA (cryoablation, $11 145; PCA, $8975; P < .01), but not when compared with epidural ($9678) or PCA with PNB ($10 303). The primary driver for increased costs was operating room supplies (PCA, $2741; epidural, $2767; PCA with PNB, $3157; and cryoablation, $5938; P < .01). With multivariate analysis, cryoablation was associated with decreased length of stay (-1.94; 95% CI, -2.30 to -1.57), opioid use during hospitalization (-3.54; 95% CI, -4.81 to -2.28), and urinary retention (0.13; 95% CI, 0.05-0.35). CONCLUSIONS: Cryoablation significantly reduces opioid requirements and length of stay relative to alternative modalities, but it was associated with an increase in total hospital costs relative to PCA, but not epidural or PCA with PNB. Cryoablation was not associated with allodynia or slipped bars requiring reoperation.

This article presents the case of a 42-year-old man who presented with superior vena cava (SVC) syndrome due to fibrosing mediastinitis with multiple failed attempts at recanalization. We initially treated him with unilateral sharp needle recanalization of the right innominate vein into the SVC stump followed by stenting. Although his symptoms improved immediately, they did not completely resolve. Six months later, he returned with worsening symptoms, and venography revealed in-stent restenosis. The patient requested simultaneous treatment on the left side. The right stent was dilated, and a 3-cm-long occlusion of the left innominate vein was recanalized, again using sharp needle technique, homing into the struts of the right-sided stent. Following fenestration of the stent, a second stent was deployed from the left side into the SVC, and the two Y limbs were sequentially dilated to allow a true bifurcation anatomy (figure). The patient had complete resolution of his symptoms and continues to do well 6 months later.

OBJECTIVE: We sought to perform a meta-analysis of the predictive value of antenatal ultrasonographic markers of bowel dilation, gastric dilation, polyhydramnios and abdominal circumference that predict complex gastroschisis and adverse perinatal outcomes DATA SOURCES: PubMed, Web of Science, Scopus and Embase were searched for relevant articles up to December 2020. Studies reporting prenatal ultrasonographic markers including intra-abdominal bowel dilation (IABD), extra-abdominal bowel dilation (EABD), bowel wall thickness, polyhydramnios, abdominal circumference <5th percentile, gastric dilation (GD) and bowel dilation not otherwise specified (BD-NOS) were included. The primary outcome was prediction of complex gastroschisis; secondary outcomes were length of hospital stay for newborn, time to full enteral feeding, postnatal mortality rate, incidence of necrotising enterocolitis and short bowel syndrome. RESULTS: Thirty-six studies were included in this meta-analysis. We found significant associations between complex gastroschisis and IABD (OR=5.42; 95% CI 3.24 to 9.06), EABD (OR=2.27; 95% CI 1.40 to 3.66), BD-NOS (OR=6.27; 95% CI 1.97 to 19.97), GD (OR=1.88; 95% CI 1.22 to 2.92) and polyhydramnios (OR=6.93; 95% CI 3.39 to 14.18). Second trimester IABD and EABD have greater specificity for the prediction of complex gastroschisis than third trimester values with specificity of 95.6% (95% CI 58.1 to 99.7) and 94.6% (95% CI 86.7 to 97.9) for the second trimester IABD and EABD, respectively. CONCLUSION: Prenatal ultrasonographic markers, especially the second trimester IABD and EABD, can identify fetuses that develop complex gastroschisis. Furthermore, these specific ultrasonographic markers can identify those babies at the highest risk for severe complications of this congenital anomaly and hence selected for future antenatal interventions.

PURPOSE: The purpose of this study is to evaluate the relationship of social continence with patient centered outcomes, such as quality of life, in children with sarococcygeal teratoma (SCT). We hypothesize there is a correlation between social continence and patient-centered outcomes. METHODS: A chart review and three surveys (Pediatric Quality of Life Inventory™ (PedsQL™), Baylor Continence Scale (BCS), and Impact on Family (IOF)) were performed for SCT patients who underwent resection at our institution from 2013 to 2018. PedsQL™ assesses quality of life, BCS evaluates global continence, and the IOF scale measures the impact of a child's illness on the family. Pearson correlation was used to examine the relationship between BCS, PedsQL™, and IOF. RESULTS: Eighteen patients were identified with 72% (13/18) participating in the surveys with a median age at time of survey of 4.7 years (range 2.8-7.9). Patients with Altman IV were diagnosed postnatally and had smaller tumors. At the time of survey administration, a majority of children were toilet trained (54%, 7/13). Parents reported urinary incontinence (46%, 6/13) more frequently than bowel incontinence (15%, 2/13). Altman III/IV trended towards worse PedsQL™, BCS, and IOF surveys; however, it was not significant. The BCS correlated with the Total PedsQL™ (ρ = -0.56, p = 0.048) and IOF (ρ = 0.68, p = 0.011). CONCLUSION: Children with SCT have a correlation between social continence, quality of life, and the impact on family. This study suggests interventions to screen and improve continence in children with SCT could also improve patient centered metrics. STUDY DESIGN: Cross-sectional study LEVEL OF EVIDENCE: Level II, Prognosis Study.

Fetus-in-fetu (FIF) is a rare congenital anomaly where a parasitic twin is within the body of a host twin. FIF is reported to occur in 1:500,000 live births. Herein, we report the first case of the medical and surgical treatment of a FIF patient who was born with extreme prematurity at 25-weeks gestation. With the multi-disciplinary coordination of neonatology, surgery, and interventional radiology, the patient was able to achieve a window of medical stability 4 weeks after birth. A decision was made at that time to proceed with an intra-abdominal and perineal resection of the FIF. The FIF was successfully resected and the patient was able to recover from the operation, with eventual discharge from the NICU. In conclusion, extreme prematurity and FIF may be amenable to surgical resection and a multi-disciplinary approach is crucial to achieve the desired outcome.
RESUMEN
OBJECTIVES: To evaluate the survival of twin-to-twin transfusion syndrome (TTTS) and concomitant twin anemia polycythemia sequence (TAPS) compared to TTTS without TAPS at the time of fetoscopic laser photocoagulation (FLP). METHODS: TTTS pregnancies undergoing FLP were divided to three groups including (i) traditional TAPS definition of middle cerebral artery (MCA) peak systolic velocity (PSV) < 1 multiple of the median (MoM) in recipient and > 1.5 MoM in the donor fetus, (ii) delta MCA-PSV > 0.5 MoM and (iii) delta MCA-PSV > 1.0 MoM. RESULTS: A total of 353 monochorionic twins underwent FLP for TTTS. Based on the traditional definition, 335 (94.9 %) had TTTS only and 18 (5.1 %) had TTTS + TAPS. There were 245 (69.4 %) TTTS only and 108 (30.6 %) TTTS + TAPS considering delta MCA-PSV > 0.5 MoM and 339 (96 %) TTTS only and 14 (4 %) TTTS + TAPS considering delta MCA-PSV > 1.0 MoM. No significant differences in survival were noted at birth or 30-days after delivery between TTTS and TTTS with TAPS patients using the traditional definition, delta > 0.5 MoM or delta > 1.0 MoM. CONCLUSION: The rate of neonatal survival at birth or at 30-days of life following FLP for TTTS only and TTTS with TAPS were not different based on any of the clinically used TAPS definitions.

INTRODUCTION: The Nuss procedure is the most common and preferred operative correction of pectus excavatum. Surgeon preference and patient factors can result in variations in Nuss procedure technique. We hypothesize that certain techniques are associated with increased risk of complications. MATERIALS AND METHODS: We performed a single-center retrospective review of Nuss operations from 2016 to 2020. Variations in intraoperative techniques included sternal elevator (SE) use, number of bars placed, and usage of bilateral stabilizing sutures. Patient demographics, intraoperative data, and postoperative outcomes were reported as median with interquartile ranges or percentages. Statistical significance (p < 0.05) was determined with Wilcoxon's rank-sum and chi-square tests. Multivariate analysis was performed to control for introduction of intercostal nerve cryoablation and surgeon volume, and reported as odds ratio with 95% confidence interval. RESULTS: Two hundred and sixty-five patients were identified. Patients repaired with two bars were older with a larger Haller index (HI). Patient demographics were not significantly different for SE or stabilizing suture use. Placement of two bars was associated with significantly increased risk of readmission. Similarly, SE use was associated with increased risk of pleural effusion and readmission. Finally, the use of bilateral stabilizing sutures resulted in less frequent slipped bars without statistical significance. CONCLUSION: Older patients with a larger HI were more likely to need two bars placed to repair pectus excavatum. Placement of multiple bars and SE use are associated with significantly higher odds of certain complications.

PURPOSE: Congenital lung malformation (CLM) volume ratio (CVR) of ≥1.1 has been shown to be highly predictive of the need for urgent, perinatal surgical intervention. The purpose of this study was to utilize this information to propose a delivery planning and clinical management algorithm based on this threshold. METHODS: A retrospective cohort study was performed for all fetuses evaluated at our fetal center between 5/2015 and 11/2020. Demographics, ultrasound findings, late gestation CVR (≥27 weeks gestational age), prenatal and postnatal treatment, and outcomes were analyzed with nonparametric univariate analysis based on late gestation CVR of 1.1. Receiver operating characteristic curve analysis was performed to evaluate association between late gestation CVR, hydrops, need for fetal intervention, and need for urgent perinatal surgery. RESULTS: Of the 90 CLMs referred to our fetal center, 65 had late gestation CVR with a majority <1.1 (47/65, 72%). All patients with late gestation CVR ≥ 1.1 were managed with resection (18/18) with most resections requiring fetal intervention or urgent neonatal resection (13/18). Late gestation CVR < 1.1 were managed with elective resection (36/47, 77%) or non-operative observation (11/47, 23%). Late gestation CVR ≥ 1.1 had 100% sensitivity and NPV for hydrops, need for fetal intervention, and need for urgent perinatal surgery. CONCLUSION: CLM with CVR ≥ 1.1 were associated with urgent perinatal surgical intervention and expectant mothers should plan for delivery at centers equipped to manage neonatal resuscitation and potential urgent neonatal resection. Conversely, CLM with CVR < 1.1 may be safe to deliver at patient hospital of choice.

BACKGROUND: Recent studies have shown intercostal cryoablation(IC) during the Nuss procedure decreases hospital length of stay(LOS) and opioid administration. However, few studies have also evaluated the risk of postoperative complications related to IC. METHODS: We performed a single center retrospective analysis of all patients who underwent Nuss procedure by one surgeon from 2/2016 to 2/2020, comparing intraoperative IC to other pain management modalities(non-IC). Primary outcomes were postoperative complications, hospital LOS, and opioid administration. Multivariate analysis was performed with outcomes reported as regression coefficients(RC) or odds ratios(OR) with 95% confidence interval. RESULTS: IC was associated with decreased hospital LOS (RC -1.91[-2.29 to -1.54], less hospital opioid administration (RC -4.28[-5.13 to -3.43]), and less discharge opioid administration (RC -3.82[-5.23 to -2.41]). With respect to postoperative complications, IC decreased the odds of urinary retention (OR 0.16[0.06 to 0.44]); however, increased the odds of slipped bars requiring reoperation (OR 36.65[5.04-266.39]). CONCLUSIONS: Our single surgeon experience controls for surgeon variability and demonstrates intraoperative IC for the Nuss procedure is an effective pain management modality that decreases hospital LOS and opioid use during hospitalization and at discharge; however, it is associated with increased odds of slipped bars requiring reoperation. LEVEL OF EVIDENCE: III.

INTRODUCTION: A shortage of medical devices designed for children persists due to the smaller pediatric population and market factors. Furthermore, pediatric device development is challenging due to the limited available funding sources. We describe our experience with pediatric device projects that successfully received federal grant support towards commercializing the devices that can serve as a guide for future innovators. METHODS: The developmental pathways of pediatric device projects at a tertiary-care children's hospital that received NIH SBIR/STTR funding between 2016-2019 were reviewed. The clinical problems, designs, specific aims, and development phase were delineated. RESULTS: Pediatric faculty successfully secured NIH SBIR/STTR funding for five pediatric devices via qualified small business concerns (SBC's). Three projects were initiated in the capstone engineering design programs and developed further at two affiliated engineering schools, while the other two projects were developed in the faculty members' labs. Four projects received funding via established SBC's, while one was awarded funding via a newly established SBC. CONCLUSION: NIH SBIR/STTR grants are an essential source of external non-dilutive funding for pediatric device innovation and especially for academic-initiated projects. This funding can provide needed early-stage support to facilitate commercialization. In addition, these grants can serve as achievable accomplishments for pediatric faculty portfolios toward academic promotion. Our experience shows that it is possible to build a robust innovation ecosystem comprised of academic faculty (clinical/engineering) collaborating with local device development companies while jointly implementing a product development strategy leveraging NIH SBIR/STTR funding for critical translational research phases of pediatric device development.

Renal lymphatic abnormalities are rare, and the understanding of pathophysiology involving renal lymphatics is limited. Symptoms can include hypertension, hematuria, proteinuria, chyluria, and abdominal and lumbar pain. Imaging techniques specific to the renal lymphatics have not been clarified. We review the intrahospital imaging evaluation/workup and clinical course of a 6-year-old male who presented to our institution with a large perirenal cyst. His presentation presented a diagnostic and management challenge. The cyst was determined to be lymphatic in origin and required multiple interventional radiology and surgical procedures for management.

Ex utero intrapartum treatment (EXIT) to airway has been described as a safe method to secure challenging fetal airways while on placental support. Herein, we present a unique case of a monochorionic-diamniotic twin pregnancy where both fetuses presented with oropharyngeal tumors requiring airway securement on placental bypass. A multidisciplinary tabletop simulation was convened to allow for personnel coordination between multiple services, OR equipment allocation, and preparation for a range of possible clinical scenarios. A tabletop simulation was chosen for planning since this is a simulation methodology commonly used for preparation in acute, high intensity multidisciplinary situations such as disaster preparation, and allows for exploration of multiple potential scenarios when outcomes are uncertain. The twins were urgently delivered for decreased fetal movement and decelerations in Twin B at 28 weeks 6 days. Twin A was delivered via EXIT to airway while Twin B had debulking of the tumor on placental support, with subsequent airway securement through a tracheostomy. In conclusion, for complex fetal procedures, detailed pre-operative planning with tabletop simulation may be a useful tool in achieving successful patient outcomes.
