Abstract
Congenital umbilicobiliary fistula is a rare disease reported in humans and dogs. A 2-month-old, intact, male French Bulldog presented with a greenish-yellow discharge dripping from the umbilicus since birth. Complete blood count and serum biochemistry were within normal limits, but serum alkaline phosphatase [...] Read more.
Congenital umbilicobiliary fistula is a rare disease reported in humans and dogs. A 2-month-old, intact, male French Bulldog presented with a greenish-yellow discharge dripping from the umbilicus since birth. Complete blood count and serum biochemistry were within normal limits, but serum alkaline phosphatase activity was mildly elevated. A positive contrast cystogram was performed to rule out a patent urachus and confirmed the presence of a vesicourachal diverticula, a type of urachal anomalies. An abdominal ultrasound and computed tomography fistulogram demonstrated a communication between the umbilicus and common bile duct, which suggested an umbilicobiliary fistula. Surgical correction of the umbilicobiliary fistula and vesicourachal diverticula was successfully performed with an uneventful recovery. Histological analysis of the fistulous tract demonstrated a cuboidal/columnar lining epithelium that transitioned to squamous epithelium near the umbilicus. Agenesis of the gallbladder was noted. The application of multiple imaging techniques in the diagnosis and surgical correction of these congenital abnormalities (umbilicobiliary fistula, gallbladder agenesis, and vesicourachal diverticula) was beneficial for treatment planning and outcome.

This retrospective study investigated the prevalence of different urachal anomalies (UA) in cats (n = 60) and dogs (n = 38) and their association with clinical symptoms and urinalysis alterations. Among UA, the vesicourachal diverticulum was the most prevalent UA diagnosed in both cats (96.7%) and dogs (89.5%): the intramural vesicourachal diverticulum was diagnosed in 76.7% of cats and 71.1% of dogs, followed by extramural vesicourachal diverticulum (20.0% and 18.4% respectively). In both cats and dogs, bladder wall diffuse or regional thickening was the most prevalent alteration. The most common alterations of the urinary bladder content were urolithiasis sediment in cats (33.3%) and in dogs (31.6%). Dogs with UA were more often asymptomatic (p = 0.01). No difference was found in cats. Stranguria, hematuria, and urethral obstruction were the most frequently reported clinical signs, while hematuria and leukocyturia were the most prevalent abnormalities at urinalysis. In conclusion, our study confirmed UA as uncommon, and often incidental findings, with a high prevalence of animals without clinical signs. Full article
