[Functional study in children with repaired esophageal atresia]. / Estudio funcional en niños con atresia esofágica corregida.

Esophageal atresia Type III was repaired in 8 children 5-11 y/o. All had stenosis in the esophagus diagnosed by radiology and endoscopy after surgical correction. Dilation was performed until normal lumen was obtained. Motor disfunction in upper and middle part of the esophagus was evidenced in six by manometry. Our findings are suggestive that Esophageal manometry is indicated in the evaluation of repaired esophageal atresia.

[Measurement of esophageal pH during 24 hours in children. Preliminary report]. / Medición del pH esofágico durante 24 horas en niños. Reporte preliminar.

A preliminary report is presented regarding the 24 hours continuous pH monitoring of 40 patients from 1 month to 19 years of age with clinical features of gastro-esophageal reflux confirmed by at least one of the diagnostic methods utilized (radiology, endoscopy, esophageal biopsy). The equipment used was a MIC GASTROGRAPH with 1.2 and 3 mm catheters according to age and using the methodology suggested by ESPGAN. Patients with reflux index of more than 10% had all other pH indexes and other diagnostic methods abnormal. The area of the curve below pH 4 correlated directly with the presence of esophagitis. Patients with post history of esophageal atresia and caustic esophagitis had marked alterations of pH. PH monitoring with the modern methodology currently available is of great help to quantify severity of acid reflux, to distinguish between physiologic pathologic reflux and to decide treatment.

[Measurement of cardia and pylorus distance by endoscopy in children]. / Medición en niños mediante endoscopia de la distancia del cardia y el píloro.

We performed upper gastrointestinal endoscopy in 258 children. We measured the distance from the teeth to cardias and pylorus and found, that height correlated with distance from then teeth to cardias.

[Chronic caustic esophagitis in childhood. A functional study]. / Esofagitis cáustica crónica en la edad pediátrica. Estudio funcional.

The purpose of this study was to investigate the motor function of the esophagus in patients with chronic caustic esophagitis. We evaluated 7 patients between 2 and 10 years of age, who had ingested caustics between 15 months and 3 years of age. The method we used was radiology with fluoroscopy vision and manometry. There was no correlation between radiologic and manometric findings. Esophageal transit was normal in all patients, even in those that had small stenosis while manometry showed motor disfunction in patients with severe esophageal damage.

[Biometry in the echosonography of the biliary tract and large abdominal vessels in normal children]. / Biometría en ecosonografía de las vías biliares y grandes vasos abdominales en niños normales.

We evaluated children younger than twelve years old with abdominal ultrasound in order to obtain normal dimensions of abdominal vessels, gallbladder and biliary tree. The measures in 183 cases increased with age in all groups.
