Colorectal hamartomatous polyposis and ganglioneuromatosis
Hereditary colorectal polyposis · Colorectal polyposis in Dachshunds · Canine colorectal hamartomatous polyposis · Kolorektale hamartomatöse Polyposis · Ganglioneuromatose des Dickdarms
What it is
This inherited condition affects the dog's lower digestive tract, specifically the colon and rectum. It causes the abnormal growth of two types of tissue: hamartomas, which are benign, disorganized mixtures of normal tissues, and ganglioneuromas, which are overgrowths of nerve tissue. Together, these growths form polyps that can obstruct the bowel and disrupt normal digestion.
How it presents
Owners typically notice symptoms in young to middle-aged dogs, which commonly include chronic or bloody diarrhea, straining to defecate, and signs of pain during bowel movements.
Treatment
There is no permanent cure for this condition, meaning lifelong management is required. Treatment typically involves repeated endoscopic or surgical removal of the growths to maintain bowel function, with expected lifetime costs ranging from €2,500 to €7,500.
