Sa1351 Baseline Esophagogastric Junction Metrics and Dynamic Esophageal Body Contraction Changes on Provocative Testing Differentiate Etiologies of Esophagogastric Junction Outflow Obstruction (EGJOO)

Evaluation of symptomatic esophagogastric junction outflow obstruction

“…Patients with anatomical EGJOO were more likely to have a shorter distal latency and therefore premature contractions, and this was also found in other reports . The reason for this finding is not entirely clear, but one possibility is that the contractile deceleration point may be difficult to identify in cases where there is compartmentalized pressurization from an obstruction.…”

“…This could be due to differences our patient population or the referral pattern in our country. Our EGJOO patients were not likely to have raised IRP due to artifacts as majority had raised IBP, thus suggestive of a true functional obstruction …”
