[Impact of esophageal manometry before anti-reflux surgery]

ABSTRACT

Esophageal hypomotility is frequent in patients with gastroesophageal reflux disease [GERD]. To precise the frequency and the patterns of esophageal manometric abnormalities in GERD patients referred before anti-reflux surgery, to determine the frequency of post-operative dysphagia and to look for associated factors with high risk of dysphagia, with special interest on pre-operative esophageal manometric study. We conducted a retrospective study based on patients having anti-reflux surgery and pre-operative esophageal manometry. Post-operative dysphagia was prospectively assessed during the follow-up. We studied 33 patients [mean age 46 years; sex ratio 0.4]. Pre-operative esophageal manometry was abnormal in 1/3 of cases, with a high prevalence of non specific motor disorders and hypomotility. Nor epidemiological, clinical or pH metric factor was associated with the risk of motor esophageal abnormalities. Post-operative dysphagia was noted in 21% of the cases, with any correlation with results of pre-operative manometry. Esophageal hypomotility is frequent in patients with GERD; and not associated with a higher risk of post-operative dysphagia after anti-reflux surgery
