Diagnostic Approach for Hypertensive Lower Esophageal Sphincter with Dysphagia and Weight Loss

Introduction to Diagnostic Guidelines

The American College of Gastroenterology recommends endoscopy with biopsy as the best diagnostic test for patients with central chest pain, dysphagia, weight loss, and hypertensive lower esophageal sphincter 1, 2

Weight loss and dysphagia are alarm features that mandate endoscopic evaluation to exclude esophageal or gastric malignancy, according to the American College of Gastroenterology 1
The American College of Gastroenterology suggests that weight loss, dysphagia, and epigastric mass have the best performance characteristics for identifying esophageal or gastric malignancies, making endoscopy the appropriate initial test 1
The American College of Gastroenterology recommends obtaining multiple esophageal mucosal biopsies (preferably at least 5 specimens) to evaluate for eosinophilic esophagitis, which can present with dysphagia and may be missed on visual inspection alone 1, 3

Endoscopy is highly accurate for esophageal cancer when multiple biopsy specimens and brushings are obtained, as stated by the American College of Radiology 2
Biphasic esophagram has 96% sensitivity for esophageal cancer, but it cannot provide tissue diagnosis or definitively exclude eosinophilic esophagitis, according to the American College of Radiology 2, 4

Barium studies are more appropriate after structural abnormalities have been excluded by endoscopy, particularly for evaluating motility disorders, as recommended by the American College of Radiology 2
CT does not assess esophageal mucosa and motility adequately, and is not indicated as initial imaging, according to the American College of Radiology 2
CT may be helpful in subsequent evaluation if initial studies are unrevealing, as stated by the American College of Radiology 2
pH monitoring is indicated after normal endoscopy findings and when evaluating PPI treatment failures, not as the initial diagnostic test with alarm features present, according to the American College of Gastroenterology 1

Failing to recognize weight loss and dysphagia as alarm features requiring immediate endoscopic evaluation can lead to delayed cancer diagnosis, as warned by the American College of Gastroenterology 1
Overlooking eosinophilic esophagitis by not obtaining adequate esophageal biopsies during endoscopy, as cautioned by the American College of Gastroenterology 1, 3
Proceeding directly to motility studies or pH monitoring without first excluding structural pathology in patients with alarm symptoms, as advised against by the American College of Gastroenterology 1
