Anatomy and disease of Esophagus

Heartburn or Pyrosis

substernal burning sensation that usually occurs within 30 minutes to 2 hours after meals and is made worse by lying down or bending over.

Dysphagia

sensation of food being delayed in its normal passage from mouth to stomach.

VIDEOFLUOROSCOPY

oropharyngeal swallow is best assessed by

Regurgitation

effortless appearance of an acid or bitter taste in the mouth.

DIFFUSE ESOPHAGEAL SPASM

Cork screw pattern

BARIUM ESOPHAGRAM WITH FLUOROSCOPY

Best initail diagnostic study of Achalasia

20mm

Normal esophagus diameter

15mm

Clinical symptom of strictures is dysphagia when the luminal diameter is less than

Esophageal Dilation

treatment of benign stricture disease

Maloney Bougies

used in uncomplicated, short, straight strictures.

WIRE-GUIDED SAVARY-GILLIARD DILATOR

best suited for long, tight, or tortuous strictures.

Esophageal Ring

circumferential, can consist of MUCOSA OR MUSÇLE, and most commonly occur in the DISTAL esophagus

BARIUM RADIOGRAPHY

most sensitive means of diagnosing esophageal webs.

Schatzki Ring

Also known as B-ring

Barium Swallow study

most sensitive test for detecting a Schatzki ring

GASTROESOPHAGEAL REFLUX DISEASE

defined as chronic symptoms or mucosal damage secondary to the abnormal reflux of gastric contents into the esophagus.

Dental Erosion

loss of tooth structure secondary to a chemical, rather than a bacterial, cause.

Barret Esophagus

Is a potentially serious complication of longstanding GERD.

Barret Esophagus

SALMON-PINK COLUMNAR MUCOSA

BARIUM SWALLOW STUDY

excellent test for the diagnosis of Zenker diverticulum.

MIDESOPHAGEAL TRACTION DIVERTICULA

only true diverticula in the esophagus.

PULSION DIVERTICULUM

results from internal forces applied to a portion of the esophageal wall.

Traction Diverticula

result of external pulling of the esophageal wall by neighboring inflammatory or fibrotic tissue, such as adjacent tuberculous mediastinitis.

ESOPHAGEAL INTRAMURAL PSEUDODIVERTICULA

multiple small outpouchings apparent on barium swallow study or endoscopy
