Colonic torsion in 4 Great Danes

Area of Science:

• Veterinary Medicine
• Gastroenterology
• Surgical Oncology

Background:

• Colonic torsion is a serious gastrointestinal condition in dogs.
• Recurrence rates and specific breed predispositions for colonic torsion are not well-established.
• Previous studies on colonic torsion in German Shepherds did not report recurrence after correction without colopexy.

Observation:

• Four Great Danes presented with non-specific gastrointestinal signs.
• Pneumocolon, identified via radiography, served as a diagnostic indicator for colonic torsion.
• Three of the four dogs had undergone gastropexy prior to torsion diagnosis.

Findings:

• Colonic torsion was diagnosed in all four Great Danes using pneumocolon on radiography.
• Two of the four dogs experienced recurrence of colonic torsion.
• One case of recurrence occurred despite a previous colopexy, indicating potential breed-specific severity.

Implications:

• Pneumocolon is a rapid, non-invasive diagnostic aid for colonic torsion.
• Great Danes appear to have a higher risk of colonic torsion recurrence compared to other breeds.
• Colonic torsion in Great Danes may represent a distinct or more severe form of the condition, warranting further investigation into underlying causes and optimal management strategies.
