Feeding and Swallowing Characteristics of Children With Esophageal Atresia and Tracheoesophageal Fistula.

OBJECTIVES: This study aimed to characterize feeding/swallowing difficulties in children with esophageal atresia and/or tracheoesophageal fistula (EA/TEF) and evaluate associations among feeding difficulties, pharyngeal dysphagia (PD), and other aerodigestive evaluation findings. METHODS: This was a retrospective cohort study of feeding/swallowing characteristics of 44 patients with EA/TEF treated in the aerodigestive program of a single academic medical institution from 2010 to 2015. Demographics, comorbidities, presence and characteristics of feeding/swallowing difficulties, and results of relevant diagnostic tests [videofluoroscopic swallow studies (VFSS), clinical feeding evaluations (CFEs), chest computerized tomography (CT) scans, pulmonary bronchoscopies, and upper GI (UGI)/esophagrams] were reviewed. RESULTS: Fifty percent of the cohort had PD and 88.6% had feeding difficulties. Across 118 encounters (87 VFSS and 31 CFEs), feeding difficulties suggestive of esophageal dysphagia were most frequently seen in children over 48 months and feeding difficulties suggestive of developmental feeding problems were most frequently seen in children from 24 to 48 months. Abnormal findings were present in 59.8% of VFSS, with aspiration (34.5%) and pharyngeal residue (26.4%) the most frequently observed signs of dysphagia. Abnormal UGI/esophagram findings were not associated with significantly increased risk of feeding difficulties during visits within 3 months (risk ratio, RR = 1.33). Presence of dysphagia was associated with increased risk for some abnormal CT findings (RR= 3.0 for airspace and 3.0 for bronchiectasis). CONCLUSIONS: Feeding/swallowing difficulties are common in EA/TEF, and types of feeding difficulties vary by patient age. The presence of abnormal findings on UGI/esophagram did not increase the risk of feeding complaints; however, the presence of dysphagia increased the risk of abnormal chest CT.

Effects of Anesthesia on Pediatric pH Impedance.

OBJECTIVES: Anesthesia can alter gastric and small intestinal motility, but its effect on gastroesophageal reflux (GER) is unclear. We set out to evaluate the effect of anesthesia on pH-multichannel intraluminal impedance (pH impedance) evaluation of GER. METHODS: Retrospective single-center analysis of 95 pH impedance probe studies performed in patients both with anesthesia exposure and esophagogastroduodenoscopy (n = 50) and without (n = 45). RESULTS: Increased acid reflux per hour, nonacid reflux per hour, and total reflux per hour were observed in the first 4 hours, both overall and in children 1 year or older and in both sedation groups. This difference remained for the older children without sedation by multiple regression analysis for nonacid reflux per hour and total reflux per hour. Patients using proton pump inhibitors had more nonacid reflux events per hour and total reflux events per hour regardless of sedation. CONCLUSIONS: Based on the results of the present study, there is no need to eliminate the data collected immediately after placement of the probe in children younger than 1 year of age, but in those who are 1 year or older without sedation, there may be a greater number of reflux events in the first 4 hours. The first 4 hours, therefore, should be carefully evaluated in patients older than 1 year of age. Further study is needed to provide normative data for the first 4 hours versus the later time period, both for those undergoing sedation and for unsedated patients, to validate the findings from the present study and to better understand the mechanism of GER.

Evaluating the yield of gastrointestinal testing in pediatric patients in aerodigestive clinic.

OBJECTIVE: To improve understanding of the interrelatedness of airway and esophageal diagnoses by evaluating the yield of procedural and radiographic testing of the gastrointestinal tract in children with airway conditions by their referring diagnoses in a pediatric aerodigestive clinic. METHODS: A retrospective chart review of all 325 patients seen in the aerodigestive program from 2010 to 2013 was performed in a single academic medical center. Demographics and results from esophagogastroduodenoscopies with biopsies (EGD), upper gastrointestinal fluoroscopy studies (UGI), and pH multichannel intraluminal impedance probe (pH-MII) performed within 30 days of the clinic visit were evaluated according to presenting diagnoses. RESULTS: Mean patient age was 3.15 years (range 0.15-24 years) and 41.2% were born premature. 189/325 (58.1%) were on acid suppression. A total of 295 EGD, 193 pH-MII, and 54 UGI were performed. The most common diagnosis with an abnormal pH-MII was asthma. The most common diagnoses with an abnormal EGD were feeding difficulty and tracheal esophageal fistula/ esophageal atresia (TEF/EA). EGDs were normal in 188/295 (63.7%), while 39/295 (13.2%) demonstrated esophagitis, and 22/295 (7.5%) had >15 esophageal eosinophils per high power field. The majority of pH-MII (144/193 [74.6%]) and UGI (47/54 [87%]) were normal. CONCLUSIONS: Children with feeding difficulty, TEF/EA, and asthma were the mostly likely to have a histologic abnormality on EGD or an abnormal pH-MII. The majority of children were previously prescribed acid suppression medication and had a referring diagnosis of gastroesophageal reflux disease but were subsequently found to have normal evaluation. Prospective studies are needed to optimize care of this population.

The continuing antenatal management program (CAMP): Outpatient monitoring of high-risk pregnancies. Keeps patients safe, costs low and care nearby.

A program was developed for referred, stable, high-risk obstetrical patients allowing them to receive antenatal care close to a tertiary hospital without the costs of a hospital admission. There were 426 women managed from September 2007 through December of 2012 with diagnosis of preterm labor, fetal anomalies, hypertensive disorders, placental abruption and other conditions. This management saved the hospital almost $9,000,000 USD or $20,956 USD per patient.
