Abstract

Canine colonic duplication is a rare congenital anomaly, usually symptomatic in the first year of life, with the
common signs of bowel obstruction. Most importantly, colonic duplication in an adult dog has not been reported. This
case document reports a non-communicating tubular colonic duplication with concurrent retroperitoneal mass in a 3-
year-old female crossbred dog, presented for further diagnosis and treatment of the abdominal mass. Without any
remarkable clinical signs, physical examination noted only abdominal distension with mild discomfort.
Ultrasonography demonstrated a large mass in the mid-caudal abdomen, a tubular mass appearance on the colonic
wall and the presence of peritoneal effusion. An exploratory laparotomy revealed a colonic tubular mass without
communication with the true lumen. An opening tract from the tubular mass to a massive distended retroperitoneal
sac was identified with a ruptured area. Surgical removal of the retroperitoneal sac and partial colectomy of the
conjoined part were accomplished with full recovery and normal defecation within 12 months of the follow-up
processes. The diagnosis of a non-communicating tubular colonic duplication was confirmed by the histopathological
result. In consideration of the abdominal mass, colonic duplication should be listed as a differential diagnosis in any
age of dog. Other associated abnormalities should be included in the investigation, in order to prevent any
complications. Surgery is recommended to achieve a final diagnosis and an applicable treatment for successful
outcomes.
