Splenectomy & Advanced Abdominal Surgery

Advanced abdominal surgery, specifically a Splenectomy, is one of the most common “major” soft tissue procedures performed by surgical groups. While it is often an emergency due to a ruptured mass, it can also be a planned elective procedure.

It is commonly recommended for masses, internal bleeding, gastrointestinal disease, or other serious abdominal conditions.

We combine advanced surgical expertise with careful perioperative care to support stability, recovery, and the best possible outcome.

Common Abdominal Surgery

Splenectomy (Spleen Removal)

The spleen acts as a blood filter and a reservoir for red blood cells. In dogs, it is prone to developing masses—some benign (like a hematoma/blood clot) and some malignant (like Hemangiosarcoma).

The Procedure

The surgeon ligates (ties off) the numerous blood vessels supplying the spleen and removes the entire organ. Because the liver and bone marrow can take over the spleen’s functions, pets can live a perfectly normal life without it.

The "Rule of Two-Thirds"

Historically, about two-thirds of splenic masses are malignant, and of those, two-thirds are hemangiosarcoma. However, a splenectomy is the only way to get a definitive diagnosis via pathology.

Expected Outcome

  • Benign: If the mass is benign (e.g., a hematoma), the surgery is 100% curative and the pet’s life expectancy returns to normal.
  • Malignant: If cancerous, the surgery stops life-threatening internal bleeding and provides a high quality of life for several months, often extended with chemotherapy.

Liver Lobectomy

This involves the partial or complete removal of a liver lobe, usually to treat a localized tumor (like Hepatocellular Carcinoma).

Advanced Tech

Surgeons often use specialized tools like Vessel Sealers (which use radiofrequency to seal large vessels) or Stapling Devices to minimize blood loss and surgery time.

Expected Outcome

Very good for “massive” (localized) liver tumors. If the tumor is completely removed, many dogs enjoy a median survival time of over 3 years.

Nephrectomy (Kidney Removal)

The removal of a kidney is typically performed due to severe infection (pyelonephritis), kidney stones that have destroyed the organ, or a tumor.

The "Function Test"

Before surgery, the surgeon must confirm via bloodwork and imaging that the other kidney is healthy enough to handle 100% of the body’s filtration needs.

Expected Outcome

Excellent, provided the remaining kidney is functional. Most pets show no external signs of having only one kidney.

Cholecystectomy (Gall Bladder Removal)

A cholecystectomy (gallbladder removal) is a major abdominal surgery typically performed to treat life-threatening conditions of the biliary system. In dogs, it is the treatment of choice for gallbladder mucoceles—where bile becomes a thick, gelatinous mucus—as well as for gallstones, severe infection (cholecystitis), or rupture.

Common Indications for Surgery

Gallbladder Mucocele
The most frequent reason for this surgery. Excessive mucus accumulates, distending the gallbladder and potentially causing a total blockage or a “kiwi-fruit” appearance on ultrasound.
Gallbladder Rupture
An emergency where the wall of the gallbladder fails, leaking highly inflammatory bile into the abdominal cavity (bile peritonitis).
Obstruction or Infection
Stones (cholelithiasis) or severe bacterial infections that do not respond to medical management.

Surgical Approach

Open Cholecystectomy

The traditional method involving a midline abdominal incision. Surgeons carefully dissect the gallbladder away from the liver and ligate the cystic duct.

Bile Duct Flushing

To ensure the remaining pathways are clear, surgeons may “flush” the common bile duct before finishing.

Laparoscopic Option

In some specialized centers, a minimally invasive approach using cameras and small ports can be used for stable, non-ruptured cases.

Expected Outcomes & Prognosis

  • Elective vs. Emergency: Outcome is heavily dependent on the pet's stability at the time of surgery.
  • Elective surgery: Performed before a rupture or severe illness; has a very low mortality rate, often around 2%.
  • Emergency surgery: For ruptured cases carries a much higher risk, with mortality rates ranging from 20% to 39%.
  • Long-Term Prognosis: For pets that survive the initial post-operative period (the first 1–2 weeks), the long-term prognosis is excellent. Dogs can live normal, healthy lives without a gallbladder.

Recovery and Potential Complications

Hospitalization

Most pets require 2–5 days in the hospital for intensive monitoring, IV fluids, and pain management.

The "Danger Period"

The first few days are critical; vets monitor closely for bile leakage or pancreatitis.

Common Side Effects

Vomiting or regurgitation is very common post-op, affecting roughly 65% of patients.

At-Home Care

Requires 10–14 days of strict rest, an E-collar to protect the incision, and often a temporary low-fat or bland diet to support the digestive system
