Abstract:
The latest Chicago Classification of esophageal motility disorders categorizes esophageal hypomotility disorders (EHD) into absent contractility (AC) and ineffective esophageal motility (IEM). While these disorders are commonly associated with gastroesophageal reflux disease (GERD), they are not pathognomonic. To improve diagnostic accuracy, provocative maneuvers during high-resolution esophageal manometry (HRM) -such as multiple rapid swallows (MRS) and single solid swallows (SSS) -have been introduced.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
