Type Ia (spherical) communicating colonic duplication in a dog treated with colectomy

Area of Science:

• Veterinary Surgery
• Comparative Pathology
• Gastrointestinal Diseases

Background:

• Colonic duplications are rare congenital anomalies in domestic animals.
• Incidental findings during abdominal surgery can present diagnostic challenges.
• Early identification and surgical intervention are crucial for successful outcomes.

Observation:

• A six-month-old Labrador retriever presented with an incidental colonic mass.
• Computed tomography revealed a spherical lesion occupying the colonic lumen with a shared blood supply.
• The lesion was suspected to be a colonic duplication.

Findings:

• Histopathology confirmed the diagnosis of a colonic duplication.
• Segmental colectomy was performed successfully during exploratory celiotomy.
• The dog experienced an uneventful recovery with no complications.

Implications:

• This case represents the first report of an asymptomatic, spherical, communicating colonic duplication in a canine patient.
• Segmental colectomy is presented as an effective surgical management strategy for colonic duplications in veterinary medicine.
• Highlights the importance of thorough diagnostic workups for incidental findings during abdominal surgery.
