Double-balloon enteroscopy in two dogs.

Area of Science:

• Veterinary Medicine
• Gastroenterology

Background:

• Conventional flexible endoscopy has limitations in reaching the deep small intestine.
• Accessing the entire small intestine for examination is diagnostically challenging.

Purpose of the Study:

• To evaluate the clinical usefulness of double-balloon enteroscopy for examining the canine small intestine.
• To assess the feasibility of the double-balloon enteroscopy technique in dogs.

Main Methods:

• The study utilized a novel double-balloon enteroscopy system with two balloons: one on the endoscope tip and one on an overtube.
• The endoscope was advanced by alternating traction between the two balloons.
• The technique was applied to two medium-sized dogs via both oral and anal routes.

Main Results:

• The double-balloon enteroscopy technique enabled complete examination of the small intestine mucosa in both dogs.
• Both oral and anal approaches were feasible for accessing the entire small intestine.

Conclusions:

• Double-balloon enteroscopy is a useful and feasible method for comprehensive examination of the canine small intestine.
• This technique overcomes previous limitations in deep small intestinal access in veterinary medicine.
