Abstract

OBJECTIVE:

To evaluate the esophageal passage of capsules in clinically normal cats and determine the incidence of prolonged transit or entrapment.

ANIMALS:

12 clinically normal adult cats.

PROCEDURE:

Esophageal transit of barium sulfate-filled capsules was evaluated fluoroscopically. Each cat was examined 3 times (36 examinations). Esophageal transit times were classified as normal (< or = 30 seconds) or prolonged (> 30 but < or = 240 seconds). Capsules were considered entrapped when transit times were > 240 seconds.

RESULTS:

Transit times were normal in 10 of the 36 (27.8%) examinations, whereas times were prolonged in 7 (19.4%) examinations. Capsules became entrapped in the midcervical region of the esophagus during 19 (52.8%) examinations. Following termination of each examination, cats with entrapped capsules were fed a small amount (0.5 to 1 ounce) of food; this resulted in passage of the capsule to the stomach.

CONCLUSIONS AND CLINICAL RELEVANCE:

The possibility of medication-induced esophagitis should be considered when orally administering ulcerogenic drugs to cats. It is recommended that a small volume of food be given following medications to ensure complete esophageal clearance.
