How the training of ultrasonographers influences the certainty of prenatal detection of congenital malformations of interest to the pediatric surgeon.

BACKGROUND: The training needed for doing obstetric ultrasounds is rarely reported. The aim of this study was to determine whether the training of the ultrasonographer influences the prenatal diagnostic certainty of some congenital malformations. METHODS: We conducted a retrospective evaluation of antepartum sonographic findings of newborn infants found ultimately to have a congenital anomaly in a tertiary level pediatric reference center. Data were collected on admission for consecutive patients at a tertiary-level pediatric reference center. The mother´s pregnancy and birth demographic variables and those of the prenatal ultrasound (PUS) were analyzed and correlated with the final diagnosis. RESULTS: Sixty-seven neonates were included. All cases underwent PUS with a mean of 4.6. Prenatal diagnosis was established in 24 cases (35.8%). Thirteen surgical anomalies were detected, particularly anorectal malformation and gastroschisis. The accuracy of PUS was associated with the training of the physician performing the PUS, whereby PUS with the greatest accuracy were performed by gynecologists and maternal-fetal specialists against radiologists and general practitioners (p = 0.005). Patients without an accurate prenatal diagnosis had a greater risk of presenting comorbidities (relative risk [RR]: 1.65, p = < 0.001, 95% confidence interval [CI]: 1.299-2.106). CONCLUSIONS: In our setting, prenatal diagnosis of these malformations is directly determined by the training of the person performing the ultrasound.

INTRODUCCIÓN: Con poca frecuencia se ha reportado el entrenamiento necesario para realizar ultrasonido (US) obstétrico. El objetivo de este estudio fue determinar si el entrenamiento del ultrasonografista influye en la certeza del diagnóstico prenatal de algunas malformaciones congénitas. MÉTODOS: Se llevó a cabo una evaluación retrospectiva de los hallazgos ultrasonográficos prenatales de neonatos que tuvieron malformaciones congénitas en un hospital de referencia pediátrico de tercer nivel. Se realizó al ingreso de neonatos consecutivos en un hospital de referencia de tercer nivel. Se recolectaron y analizaron datos del embarazo y alumbramiento, así como los de los ultrasonidos prenatales (USP) correlacionando con el diagnóstico final. RESULTADOS: Se incluyeron 67 neonatos. Todos tuvieron USP con media de 4.6. Se realizó diagnóstico prenatal en 24 casos (35.8%). Se detectaron 13 malformaciones congénitas, predominando malformación anorectal gastrosquisis. La certeza del USP se asoció con el entrenamiento del individuo que realizó el US y la mayor certeza se encontró cuando lo realizaron ginecólogos y especialistas materno-fetales contra radiólogos y médicos generales (p = 0.005). Los pacientes sin diagnóstico prenatal certero tuvieron mayor riesgo de presentar comorbilidades (riesgo relativo [RR]: 1.65, p = < 0.001, 95% intervalo de confianza [CI]: 1.299-2.106). CONCLUSIONES: En nuestro medio, el diagnóstico prenatal de estas malformaciones está determinado directamente por el entrenamiento de la persona que realiza el ultrasonido.

A Gastroschisis bundle: effects of a quality improvement protocol on morbidity and mortality.

OBJECTIVE: Gastroschisis incidence is rising. Survival in developed countries is over 95%. However, in underdeveloped countries, mortality is higher than 15% often due to sepsis. The aim of this study was to evaluate the effect on morbidity and mortality of a Quality Improvement Protocol for out-born gastroschisis patients. METHODS: The protocol consisted in facilitating transport, primary or staged reduction at the bedside and sutureless closure, without anesthesia, PICC lines and early feeding. Data was prospectively collected for the Protocol Group (PG) treated between June 2014 through March 2016 and compared to the last consecutive patients Historical Group (HG). Primary outcome was mortality. SECONDARY OUTCOMES: need for and duration of mechanical ventilation (MV), time to first feed (TFF) after closure, parenteral nutrition (TPN), length of stay (LOS) and sepsis. Data were analyzed using χ2 and Mann-Whitney U tests. RESULTS: 92 patients were included (46 HG and 46 PG). Demographic data were homogeneous. Mortality decreased from 22% to 2% (p = 0.007). Mechanical ventilation use decreased from 100% to 57% (p = <0.001), ventilator days from 14 to 3 median days (p = <0.0001), TPN days: 27 to 21 median days (p = 0.026), sepsis decreased from 70% to 37% (p = 0.003) and anesthesia from a 100% to 15% (p = <0.001), respectively. No difference was found in NPO or LOS. CONCLUSION: A major improvement in the morbidity and mortality rates was achieved, with outcomes comparable to those reported in developed countries. It was suitable for all patients with gastroschisis. We believe this protocol can be implemented in other centers to reduce morbidity and mortality. LEVEL OF EVIDENCE: III.

Chylous Ascites in a Newborn with Gastroschisis. Case Report.

Chylous ascites is a rare disease, only two cases associated with gastroschisis have been published. We report a case treated conservatively with total parenteral nutrition (TPN) and octreotide. We reviewed the literature about management options for the chylous ascites.
