The effect of body position and gravitational pull on the complex pressure-driven process of pharyngeal swallowing remains unknown. Using high-resolution manometry (HRM), this study aims to identify positional adaptations of pharyngeal physiology by evaluating swallowing pressure patterns in a series of inverted body positions. Ten healthy adults each underwent swallowing tasks with pharyngeal HRM at six body positions using an inversion table (0°[upright], 45°, 90°[supine], 110°, 135°, and 180°[fully inverted])...

BACKGROUND: Experience of peroral endoscopic myotomy (POEM) for treatment of achalasia in pediatric population is limited with varying techniques in different centers. The accurate extent of submucosal tunneling into the gastric cardia and the adequacy of myotomy are the important determining factors to success of POEM. A majority of studies in pediatric population have described using submucosal dye injection for assessing the adequacy of myotomy, however, this is a rather crude and inaccurate method...

BACKGROUND: During the past decade, laparoscopic adjustable gastric banding (LAGB) was one of the most popular surgical procedures in treating morbid obesity. Long-term effects, specifically on esophageal motility, of LAGB have not been well described in the literature despite the high prevalence of reoperations and post-operative dysphagia. We aimed to characterize esophageal dysmotility after long-term follow-up using data of high-resolution esophageal manometry (HRM) performed in patients who presented for LAGB removal...

Background: Patients with symptoms suggestive of gastroparesis exhibit several symptoms, such as epigastric pain, postprandial fullness, bloating and regurgitation. It is uncertain if such symptoms reflect underlying oesophageal motor disorder. Aims: To examine whether patients with epigastric pain and postprandial distress syndrome suggestive of functional dyspepsia and/or gastroparesis also have concomitant oesophageal motility abnormalities and, if so, whether there are any associations between these disturbances...

BACKGROUND & AIMS: Esophageal retention is typically evaluated by timed barium esophagram in patients treated for achalasia. Esophageal bolus clearance can also be evaluated using high-resolution impedance manometry. We evaluated the associations of conventional and novel high-resolution impedance manometry metrics, esophagram, and patient-reported outcomes (PRO) in achalasia. METHODS: We performed a prospective study of 70 patients with achalasia (20-81 years old, 30 female) treated by pneumatic dilation or myotomy who underwent follow-up evaluations from April 2013 through December 2015 (median 12 months after treatment; range, 3-183 months)...

OBJECTIVE: Topical nasal anesthetic (TNA) is used when evaluating pharyngeal swallowing with high-resolution manometry (HRM). It is unclear if desensitizing the nasal mucosa improves procedure tolerability or affects pharyngeal pressure. This study evaluated the effects of TNA on comfort and pharyngeal pressure using HRM. METHODS: A double-blinded study was conducted with 20 healthy participants ( x¯ = 27 years). Participants performed five saliva and five 10-mL swallows during two exams with ManoScan HRM ESO catheter (Medtronic, Minneapolis, MN) randomized under placebo (nonanesthetic lubricant) and anesthetized (0...

BACKGROUND: In achalasia, muscle spasm may involve the proximal esophagus. When the muscle spasm is located in the proximal esophagus, conventional per oral endoscopic myotomy (POEM) may not be sufficient to relieve symptoms. In this paper, we describe retrograde endoscopic myotomy (REM) as a novel approach to perform myotomy of the proximal esophagus, with the application of a navigation tool for anatomical guidance during REM. We aim to evaluate the feasibility and safety of REM and usefulness of the navigation during REM...

BACKGROUND: Parkinson's disease (PD) can cause severe dysphagia, especially later in disease progression. Early identification of swallowing dysfunction may lead to earlier intervention. Pharyngeal high-resolution manometry (HRM) provides complementary information to videofluoroscopy, with advantages of being quantitative and objective. Artificial neural network (ANN) classification can examine non-linear relationships among multiple variables with relatively low bias. We evaluated if ANN techniques could differentiate between patients with PD and healthy controls...
