Esophageal Motility in the Supine and Upright Positions for Liquid and Solid Swallows Through High-resolution Manometry

AbstractSingle water swallow (SWS) high-resolution manometry (HRM) may miss relevant esophageal motility disorders. Solid test meal (STM) during HRM and lately the functional lumen imaging probe (FLIP) have been shown to be of diagnostic value in the assessment of motility disorders. We aimed to assess the diagnostic yield of STM and FLIP in non-obstructive dysphagia (NOD). Patients assessed for dysphagia with both HRM and FLIP between April 2016 and August 2019 were analyzed for signs of non-obstructive EGJ outflow obstruction (EGJOO) according to Chicago Classification 3.0 (CCv3) and CC adapted for the use with solid swallows (CC-S), followed by an individual group-specific analysis. Five subjects without dysphagia served as control group. Standard HRM- and FLIP-values as well as esophagograms and Eckardt Scores were analyzed. Forty-two patients were identified (male/female, 14/36, median age 62). Twenty-five (59.5%) were diagnosed with EGJOO during STM only (= SWS-negative patients; CC-S). The EGJ distensibility index (EGJ-DI) of symptomatic patients was significantly lower compared to the control group (p = 0.006). EGJ-DI was < 3mm2/mmHg in 67% and 88% of patients diagnosed according to CC-S and CCv3, respectively. The IRP during STM showed a significant association to the corresponding EGJ-DI values (p < 0.001). Seventy-six percent of patients received treatment because of additional STM evaluation with a favorable clinical response rate of 89%. STM and FLIP identify EGJOO in symptomatic patients with normal SWS during HRM. STM resembles an inexpensive and clinically meaningful option to diagnose motility disorders and helps to select patients for interventional treatment.

Ineffective Esophageal Motility

Abstract Aim The aim of this study was to evaluate esophageal motility before and after Magnetic Sphincter Augmentation (MSA) for medically refractory Gastro-Esophageal Reflux Disease (GERD). Background and Methods MSA (LINX® Reflux Management System) is intended for patients with chronic GERD with incomplete symptom relief from proton-pump inhibitors (PPI) and abnormal acid exposure. A prospectively collected database of patients who underwent MSA between 2007 and 2019 was queried. All patients who completed pre- and post-operative high-resolution manometry (HRM) were included in the study. Additional investigations included Health-Related Quality of Life (GERD-HRQL) questionnaire, Functional Outcome Swallowing Scale (FOSS), upper gastrointestinal endoscopy, barium swallow, and 24-96 hours pH-study. Data were analyzed using Wilcoxon signed rank test and McNemar test. Results Forty-five patients met the inclusion criteria. The median follow-up was 10 months (IQR 6). Compared to baseline, there was a statistically significant reduction in PPI use (p=0.000), rate of heartburn (p=0.000), regurgitation (p=0.008), and extra-esophageal symptoms (p=0.000). Only three (6.7%) patients required dietary changes. The GERD-HRQL score significantly improved (p=0.000). There was a significant increase in the Lower Esophageal Sphincter (LES) competency, including LES length (p=0.004) and Esophago-gastric Contractile Integral ((EGJ-CI) (p=0.000). A significant increase in integrated relaxation pressure (IRP) (p=0.000), mean Distal Contractile Integral (DCI) (p=0.008) and intrabolus pressure (p=0.000) was also found. Thirteen (28.9%) patients presented pre-operative Ineffective Esophageal Motility (IEM) and five of them resolved postoperatively. Two patients (4.4%) developed IEM after surgery: both had IRP and DCI values within normal limits, and one of them complained of dysphagia. However, the GERD-HRQL score recovered in both patients. Conclusion MSA was clinically effective in relieving both typical and atypical GERD symptoms. LES competency increased after MSA. EGJ outflow obstruction was uncommon and not associated with symptoms. Finally, ineffective esophageal motility may reverse to normal after MSA.
