Introduction Intraluminal esophageal impedance (ILEE) has the potential to measure esophageal luminal distension during swallow-induced peristalsis in the esophagus. A potential cause of inaccuracy in the ILEE measurement is the swallow-induced air i

Cardiac loops have been used extensively to study myocardial function. With changes in cardiac pump function, loops are shifted to the right or left. Functional luminal imaging probe (FLIP) recordings allow for loop analysis of the anal sphincter and

The external anal sphincter (EAS) may be injured in 25–35% of women during the first and subsequent vaginal childbirths and is likely the most common cause of anal incontinence. Since its first description almost 300 years ago, the EAS was believed

IntroductionThe current "gold standard" to diagnose anal sphincter morphology and disruptions utilizes low-frequency (3-9MHz) ultrasound (US) imaging techniques that provide a general outline of the sphincter muscles, but not their microstructural de

A subthreshold pharyngeal stimulus induces lower esophageal sphincter (LES) relaxation and inhibits progression of ongoing peristaltic contraction in the esophagus. Recent studies show that longitudinal muscle contraction of the esophagus may play a

We aimed to determine anatomy and function of anal sphincter complex using three-dimensional ultrasound (3D-US) and manometry in asymptomatic parous women. 3D-US of puborectalis muscle (PRM), external (EAS), and internal anal sphincters (IAS) anatomy

Background & Aims Achalasia esophagus is characterized by loss of peristalsis and incomplete esophagogastric junction (EGJ) relaxation. We studied mechanisms of esophageal emptying in patients with achalasia using simultaneous high-resolution manomet

Background & Aims Three-dimensional ultrasound (3D-US) imaging is a powerful tool to visualize various components of the anal sphincter complex, that is, the internal anal sphincter (IAS), the external anal sphincter (EAS), and the puborectalis muscl

Background: Esophageal motility, as measured by manometry, is normal in the majority of patients with eosinophilic esophagitis (EoE). However, manometry measures only the circular muscle function of esophagus. The goal of our study was to assess circ

BACKGROUND: Patients with achalasia, diffuse esophageal spasm (DES), and nutcracker esophagus have a thicker muscularis propria than normal subjects. The goal of our study was to determine the prevalence of increased muscle thickness in a group of un
