Successful Management of Esophageal Perforation with Self-Expandable Metal Stent following Pneumatic Dilation for Achalasia Cardia

Journal of Digestive Endoscopy, 2019
Achalasia cardia is the most common cause of motor dysphagia. Pneumatic dilation (PD) of lower esophageal sphincter remains the cornerstone of treatment. However, it is associated with esophageal perforation in some cases. We present a case of esophageal

Mechanics of Sphincter Action. STUDIES ON THE LOWER ESOPHAGEAL SPHINCTER [PDF]

Journal of Clinical Investigation, 1973
The purpose of this study was to evaluate the mechanical factors involved in the genesis of lower esophageal sphincter pressure. We determined the relationship between intraluminal pressure and inside diameter, estimated the ratio between the wall thickness to inside radius, and calculated the tension in the wall of the lower esophageal sphincter as a ...

A functional study of the esophagus in patients with non-cardiac chest pain and dysphagia

The Turkish Journal of Gastroenterology, 2015
Background/Aims: Nutcracker esophagus and non-specific motility disorders are the main causes of non-cardiac chest pain (NCCP), with gastroesophageal reflux in 60% of cases. Achalasia and diffuse esophageal spasm are the most frequent anomalies described

Comparison of scope holding sign on endoscopy and lower esophageal sphincter contraction on high‐resolution manometry: A pilot study

DEN Open, 2022
Objectives Lower esophageal sphincter (LES) plays a key role in gastroesophageal reflux disease (GERD) pathogenesis. In retroflexion and under sufficient insufflation, it can be seen how the lower esophagus grasps the endoscope, which we named scope ...

Muscular Equivalent of the Lower Esophageal Sphincter

Gastroenterology, 1979
In order to measure muscle thickness and to define the muscular architecture at the gastroesophageal function, both en bloc fixation and a new method of preparing dried fiber specimens were used. Specimens were obtained from 32 kidney donors and human cadavers. Wall thickness was measured at 32 identical locations in the esophagus and stomach.

Electrohydraulic Folding Ring Actuators for Radially Contracting Applications

Advanced Science, EarlyView.
This work presents an Electrohydraulic Folding Ring Actuator that combines high‐performance electrohydraulic actuation with origami‐inspired folding geometry to achieve constricting radial actuation. This integration yields significant inner lumen constriction, alongside a gripping force capable of holding objects exceeding four times the actuator's ...

Multiple huge epiphrenic esophageal diverticula with motility disease treated with video-assisted thoracoscopic and hand-assisted laparoscopic esophagectomy: a case report

Surgical Case Reports, 2017
Background Epiphrenic esophageal diverticulum is a rare condition that is often associated with a concomitant esophageal motor disorder. Some patients have the chief complaints of swallowing difficulty and gastroesophageal reflux; traditionally, such ...

Clinical utility of pharyngeal high‐resolution manometry with impedance for upper esophageal sphincter dysfunction in gastroenterology

Advances in Digestive Medicine, EarlyView.
Abstract Pharyngeal high‐resolution manometry with impedance (P‐HRM‐I) is an established assessment method used to evaluate pharyngeal swallowing. It provides precise quantification of swallowing biomechanics that enable the detection of alterations in swallowing physiology.

GLP‐1 Receptor Agonists and Endoscopy: Understanding Gastric Stasis, Aspiration Risk, and Contemporary Peri‐Procedural Guidance

Chronic Diseases and Translational Medicine, EarlyView.
Pharmacological mechanisms and physiologic effects of GLP‐1 receptor agonists relevant to peri‐endoscopic risk. ABSTRACT The global increase in obesity, type 2 diabetes mellitus (T2DM), and metabolic dysfunction‐associated steatotic liver disease (MASLD) has led to a higher use of glucagon‐like peptide‐1 receptor agonists (GLP‐1RAs) among patients ...

Regurgitation in healthy and non healthy infants

Italian Journal of Pediatrics, 2009
Uncomplicate regurgitation in otherwise healthy infants is not a disease. It consists of milk flow from mouth during or after feeding. Common causes include overfeeding, air swallowed during feeding, crying or coughing; physical exam is normal and weight
