A recent study (JL Yasuda et al. JPGN 2019; 69: 163-70) shows that esophagitis is common with and without proton pump inhibitor (PPI) therapy in children with esophageal atresia (EA).
Background: This study encompassed 310 patients (34% long gap EA) and 576 endoscopies (median age 3.7 years)
- Erosive esophagitis was found in 8.7% of patients.
- 15.2% of patients had esophagitis with >15 eos/hpf; 49% of patients had ≥1 eos/hpf (histologic eosinophilia)
- 87% of endoscopies were preceded by acid suppression therapy; being on acid suppression reduced the odds for abnormal esophageal biopsy (P=0.011).
- Histologic esophagitis was “highly prevalent even with high rates of acid suppressive medications use.”
- For example, among those receiving PPI monotherapy, 150 had normal biopsy and 136 had abnormal biopsy. Among those off all acid suppression, 30 had normal biopsy and 45 had abnormal biopsy.
- For erosive esophagitis, this occurred in 12 on PPI and was not present in 274 on PPI therapy. Among those off all acid suppression, 4 had erosive esophagitis and 70 did not.
- Presence or integrity of fundoplication was not significantly associated with esophagitis.
While this is a large study, the findings have several limitations. This is a single center retrospective study and this center attracts highly complex cases of EA.
My take: In addition to fairly high rates of erosive esophagitis and eosinophilic esophagitis, this study shows a high incidence of microscopic esophagitis, the significance of this is unclear. This study supports the current recommendations of 3 endoscopies in childhood and perhaps more frequent surveillance in those with more complex EA.
