Laparoscopic Cholecystectomy
Minimally invasive gall bladder surgery for dogs
Laparoscopic cholecystectomy is the removal of the gall bladder through small ‘keyhole’ incisions rather than a single large surgical wound. At Queensland Veterinary Specialists, this minimally invasive technique is available for suitable dogs – particularly those diagnosed early, before they become unwell. Because planned surgery is far safer than emergency surgery, early keyhole removal offers the best chance of a smooth recovery and an excellent long-term outcome.
What is a gall bladder mucocele?
A gall bladder mucocele is the most common gall bladder condition requiring surgery in dogs. It occurs when bile becomes abnormally thick and mucus-like and accumulates inside the gall bladder instead of flowing normally into the intestine. Over time the gall bladder becomes distended, and the thickened material can block the outflow of bile. In more advanced cases the gall bladder wall can become inflamed or die, and the gall bladder may rupture – releasing bile into the abdomen and causing a life-threatening bile peritonitis.
Mucoceles exist along a spectrum. Some are found incidentally on an ultrasound performed for another reason, before a dog shows any signs at all. Others present as an emergency once the gall bladder is obstructed or has ruptured.
Why do they form, and which dogs are at risk?
Mucoceles develop from a combination of sluggish bile flow and excessive mucus production by the gall bladder wall. Most affected dogs are middle-aged to older small-breed dogs, and several factors increase the risk:
- Hormonal conditions such as Cushing’s disease and hypothyroidism
- High blood fats – raised cholesterol or triglycerides (hyperlipidaemia)
- Predisposed breeds, including the Shetland Sheepdog, American Cocker Spaniel and Miniature Schnauzer (a genetic factor is recognised in some Shetland Sheepdogs)
- Dogs found to have biliary “sludge” on a routine ultrasound
How is it diagnosed?
Diagnosis is usually made on abdominal ultrasound, where a mucocele produces a characteristic ‘kiwi fruit’ or stellate (star-shaped) pattern of immobile bile. Blood tests often show raised liver enzymes (ALP, ALT and GGT) and, in more advanced cases, raised bilirubin (jaundice). Additional tests – such as screening for underlying hormonal disease and a clotting profile – help us confirm the diagnosis and prepare your dog safely for anaesthesia.
Why surgery is recommended
Because of the way the disease develops, a mucocele cannot be reliably cured with medication – the congested bile continues to accumulate, and the condition often progresses despite medical treatment. Surgical removal of the gall bladder (cholecystectomy) is the definitive treatment, and the timing of that surgery has a dramatic impact on outcome:
- Elective surgery is much safer. In dogs operated on before they become unwell, reported mortality is low – in the order of 2%.
- Emergency surgery carries far greater risk. Once the disease is advanced, reported mortality rises steeply, to roughly 20–40% in various studies.
- Rupture and infection increase risk. In a large study of 516 dogs, gall bladder rupture and infected bile were each associated with roughly a three-fold higher risk of death within two weeks of surgery.
- Clinical signs signal higher risk. Dogs already showing vomiting, lethargy, poor appetite or jaundice have poorer outcomes than those whose mucocele is found incidentally.
The encouraging news is that dogs which recover well from surgery have an excellent long-term outlook, and recurrence is uncommon because the entire gall bladder is removed. This is why we strongly recommend acting early, while a dog is still well.
The laparoscopic (keyhole) procedure
Under general anaesthesia, three to four small incisions (each around 1 cm) are made in the abdomen. A camera provides a clear, magnified view inside the abdomen, and fine instruments are used to carefully free and remove the gall bladder.
At QVS we use near-infrared (NIR) fluorescence guidance: an injected fluorescent dye makes the gall bladder and bile ducts glow green in real time, helping our surgeons clearly identify and protect the delicate biliary structures before anything is clipped or divided. This technology, now standard in human keyhole surgery, adds an important margin of safety for our canine patients.

Why choose laparoscopic surgery?
Compared with traditional open abdominal surgery, the keyhole approach offers several advantages for suitable dogs:
- Less pain after surgery
- Smaller incisions and minimal tissue trauma
- A shorter hospital stay and faster return to normal activity
- A lower risk of wound-related complications
Dogs that are already very unwell, or that have a ruptured gall bladder, are usually better served by traditional open surgery – our specialists will always recommend the safest approach for your dog.
Recovery
Most dogs recover quickly and go home within one to two days of surgery. Activity is restricted for around 7–10 days – short lead walks only, with no running, jumping or rough play – before a gradual return to normal. We provide detailed post-operative instructions, and ask you to contact us if the incision sites look red, swollen or discharge, if your dog will not eat or drink, or if vomiting or lethargy develops rather than steady improvement.
Take home points
- A gall bladder mucocele is a slowly progressive condition that can become a life-threatening emergency if the gall bladder ruptures.
- It is often diagnosed as an incidental finding on abdominal ultrasound.
- It is best treated by removing the gall bladder before clinical signs develop, when the risk of surgery is lowest and the long-term outlook is excellent.
- Laparoscopic (keyhole) cholecystectomy, with fluorescence guidance, is available at QVS for suitable elective cases.
Next steps
Having multiple specialists working across our hospitals allows us to offer surgery within days of contacting the hospital. If your general practice vet has recommended specialist referral, or you would like to discuss treatment, please contact us to arrange a consultation. Our team will also provide a detailed estimate of costs, tailored to your dog’s individual needs.
If you have concerns for your pet, we recommend discussing it with your primary care vet in the first instance, or get in touch with our team for more info.
