Derangement of esophageal anatomy and motility in morbidly obese patients: a prospective study based on high-resolution impedance manometry.

CONCLUSIONS: The obese patients had a higher lower esophageal sphincter 4-second integrated relaxation pressure and higher prevalence of EGJ outflow obstruction and m-HH than the healthy volunteers. The presence of m-HH was strongly associated with erosive esophagitis. The absence of GERD symptoms in morbid obesity was not necessarily suggestive of negative esophagogastroduodenoscopy and HRIM findings, and the discrepancy existed between esophagogastroduodenoscopy and HRIM for diagnosing HH. A comprehensive evaluation of the EGJ anatomy and esophageal function may be considered before bariatric surgery. PMID: 32868173 [PubMed - as supplied by publisher]
