Endoscopic hemostasis in acute esophageal variceal bleeding.

Acute variceal bleeding (AVB) is a milestone event for patients with portal hypertension. Esophageal varices bleed because of an increase in portal pressure that causes the variceal wall to rupture. AVB in a patient with cirrhosis and portal hypertension is associated with significant morbidity and mortality. The initial management of these patients includes proper resuscitation, antibiotic pro...

Pharmacologic identification of the lower esophageal sphincter.

The distal 2/3 of the opossum esophagus contains only smooth muscle. Manometry shows that the most distal 1-2 cm is the lower esophageal sphincter. We used a variety of agonists to seek differences between circular muscle from the sphincteric segment and more rostral levels. Isometric contractions of strips from the distal 6 cm were recorded in vitro in response to acetylcholine, carbachol, met...

Pathophysiology of GERD: Lower Esophageal Sphincter Defects

44 INTRODUCTION T he most common cause of gastroesophageal reflux disease (GERD) is lower esophageal sphincter (LES) dysfunction. The LES is a 3–4 cm high-pressure zone of muscular activity in the distal esophagus. The LES is anatomically and histologically distinct from the esophageal body. Manometric and radiographic studies can be used to identify the LES. Intraluminal manometry can detect t...
