Cholecystectomy

Cholecystectomy is recommended when the gallbladder cannot be managed safely with medication alone or when rupture risk is unacceptably high. Specific indications include:

• Gallbladder mucocele — a gel-like accumulation of bile that prevents normal emptying and predisposes the wall to necrosis (tissue death) and rupture
• Necrotizing (severe) cholecystitis with wall breakdown or impending rupture detected on ultrasound
• Confirmed or suspected gallbladder perforation with bile peritonitis — a surgical emergency
• Cholelithiasis (gallstones) causing obstruction, recurrent infection, or significant pain
• Gallbladder neoplasia (cancer) without evidence of widespread spread

Shetland Sheepdogs, Miniature Schnauzers, and Cocker Spaniels are among the breeds overrepresented for mucocele. Many cases are caught during routine abdominal ultrasound in dogs being evaluated for elevated liver enzymes or abdominal discomfort.

Cholecystectomy is performed under general anesthesia with meticulous attention to the bile duct and surrounding vessels, which lie in close proximity to the gallbladder:

• A midline abdominal incision exposes the liver, gallbladder, and hepatic duct structures
• The cystic duct (the duct connecting the gallbladder to the common bile duct) is carefully ligated and divided, preserving normal bile flow into the intestine
• The gallbladder is dissected free from its attachment to the liver's gallbladder fossa and removed intact when possible — this prevents bile spillage
• If bile peritonitis is already present, the abdomen is copiously flushed and, in some cases, a temporary drain is placed
• The common bile duct is tested for patency (open flow) to confirm bile can still reach the intestine after the cystic duct is tied off
• The specimen is sent to pathology; the abdomen is closed in layers

The liver continues to produce bile, which now flows directly from the hepatic ducts into the common bile duct and intestine — digestion is not impaired long-term.

Pre-operative evaluation is especially important because gallbladder disease often causes secondary liver and clotting abnormalities:

• Comprehensive liver panel, bilirubin, albumin, and clotting tests (PT/PTT) — elevated bilirubin signals that obstruction may already be present
• Abdominal ultrasound to confirm mucocele or wall changes and assess the common bile duct for obstruction or dilation
• IV antibiotics are started before surgery to reduce infection risk, particularly when cholecystitis is suspected
• Fluids and supportive care are initiated to stabilize blood pressure and liver perfusion
• Food is withheld the night before; water is typically allowed until morning of surgery

For true emergencies — bile peritonitis from rupture — stabilization and surgery must happen quickly. The team coordinates this rapidly and keeps you informed throughout.

Recovery depends heavily on whether surgery was planned or an emergency. Uncomplicated elective cholecystectomy typically follows this course:

• Hospitalization (1–2 days): IV fluids, pain management, IV antibiotics, and liver enzyme monitoring
• Days 2–10 at home: small, frequent, low-fat meals to reduce bile demand; restricted activity; oral antibiotics if infection was confirmed
• Week 2 recheck: incision inspection and repeat liver bloodwork to confirm values are trending toward normal
• Weeks 3–6: gradual return to a regular diet and normal activity as bloodwork normalizes

For cases complicated by bile peritonitis, hospitalization is longer (often three to five days) and recovery takes an additional week or two. A low-fat diet is often maintained long-term in breeds prone to repeat biliary disease.

Cholecystectomy carries moderate to significant surgical risk depending on the disease stage at the time of surgery:

• Bile duct injury — the cystic duct and common bile duct are in close anatomical proximity, and inadvertent damage would impair bile drainage; careful surgical technique minimizes this
• Post-operative bile leakage from incomplete duct ligation, requiring prompt recognition
• Peritonitis if bile contamination is already present at surgery — managed with thorough lavage and drainage
• Anesthetic complications in patients with significant liver dysfunction or coagulation defects
• Incision infection or seroma as with any abdominal surgery

Outcomes are significantly better when mucocele or cholecystitis is caught before rupture — this is one of the strongest arguments for routine monitoring of at-risk breeds. Surgery performed before the gallbladder ruptures carries a far better prognosis than emergency surgery for bile peritonitis.
