Effects of high-resolution esophageal manometry on oxygen saturation and hemodynamic function

The effect of high-resolution esophageal manometry (HRM) on oxygen saturation (SaO2) and hemodynamic function has not been previously evaluated. This was a prospective study of consecutive patients referred for HRM. Demographic and clinical data were collected on all patients. The study variables included SaO2, heart rate (HR) and blood pressure (BP). SaO2 and HR were measured at baseline, during intubation, during and 5 min after HRM. BP was measured at baseline, during and after HRM. 158 (56% women) patients with a mean age of 56 (SD 15) years were included. Thirty-five (22%) were obese and 55 (35%) were overweight. Eighteen (12%) patients had a history of respiratory disease and 27 (17%)…

Decreased Esophageal Sensitivity to Acid in Morbidly Obese Patients: A Cause for Concern?

Background/Aims: To evaluate esophageal sensitivity to acid between morbidly obese (MO) patients and non-MO controls with abnormal esophageal acid exposure. Methods: We conducted a cross-sectional study of 58 patients: 30 MO (cases) and 28 non-MO (controls). Esophageal symptoms and esophageal sensitivity to 0.1 M hydrochloric acid solution (Bernstein test) were compared between MO and non- MO patients with a prior diagnosis of abnormal esophageal acid exposure. Results: MO patients were less symptomatic than non-MO controls (14% vs 96%; odds ratio [OR], 0.006; 95% confidence interval [CI], 0.001 to 0.075; p=0.000). MO patients were more likely to present with decreased esophageal sensitivit…
