A case of a true lower-esophageal web is reported. The web was not visualized on radiological examination, but was visualized and removed by endoscopy. The purpose of this report is to point out that true lower-esophageal webs are different from lower-esophageal rings. Lower-esophageal webs occur much less frequently than lower-esophageal rings but must be included in the differential diagnosis of dysphagia.

Role of endoscopy in patients with achalasia.

Achalasia is an esophageal motility disorder characterized by impaired lower esophageal sphincter relaxation and peristalsis of the esophageal body. With the increasing prevalence of achalasia, interest in the role of endoscopy in its diagnosis, treatment, and monitoring is also growing. The major diagnostic modalities for achalasia include high-resolution manometry, esophagogastroduodenoscopy, and barium esophagography.

Article Synopsis
- * The evaluation targets the entire upper gastrointestinal tract, focusing on both esophageal function and structural issues like tumors and strictures.
- * Techniques like mono- and double-contrast esophagrams help assess lower esophageal sphincter function, complementing other diagnostic methods such as endoscopy and manometry.
Webs of the lower esophagus: a complication of gastroesophageal reflux?
AJR Am J Roentgenol
February 1984
Seven patients with webs within 6 cm of the gastroesophageal junction were identified from 5109 barium studies of the esophagus covering a 10-year period (incidence, 0.14%). These webs were clearly distinct from the B-ring at the gastroesophageal junction itself.

Disordered motility is better evaluated with a cine-esophagram. Recent application of radioisotopes has been useful in evaluation of esophageal reflux and the post-treatment of achalasia.
