Acute abdomen surgery in pets - Emergency operations explained

Acute abdominal surgery refers to emergency procedures in the abdominal cavity that are needed for life-threatening conditions. In dogs and cats, an acute abdomen can result from an intestinal obstruction, gastric torsion, splenic rupture, or severe infections. These situations require rapid recognition and immediate surgical treatment to save the animal's life.

In this article, we discuss the causes, symptoms, diagnosis, and the most important emergency operations within acute abdominal surgery in pets.

An acute abdomen involves the sudden onset of severe abdominal pain, often caused by a condition that requires urgent treatment. Examples include an intestinal blockage, gastric torsion, bleeding in the abdomen, or a severe infection. These situations can deteriorate very quickly and put the animal's life at risk. The faster a diagnosis is made and treatment started, the greater the chance of recovery.

Acute abdominal pain (emergency) versus ordinary abdominal pain (not an emergency)

Ordinary abdominal pain (not an emergency)

This is usually mild and often caused by something harmless, such as a slight gastrointestinal upset or something the animal didn't tolerate well.
The animal may:

• Still walk around normally and rest comfortably
• Occasionally skip a meal but otherwise remain stable
• Gradually improve within a few hours

In these cases, you can often simply observe the animal and temporarily offer a light diet or rest, as long as no warning signs develop.

Acute abdominal pain (an emergency)

Here the abdominal pain is severe, sudden, and abnormal behavior is usually immediately noticeable.
The animal:

• Is restless, won't stay lying down, or constantly changes position
• Refuses to eat and may vomit or retch
• Seems truly "not itself" or appears ill, painful, or weak

These are signs where it is not safe to wait and see. In these situations, immediate contact with a veterinarian is essential.

Causes of an acute abdomen in pets

• Gastric dilatation-volvulus (gastric torsion)
• Intestinal obstruction or perforation caused by a foreign object
• Splenic bleeding or rupture
• Uterine infection (pyometra)
• Bladder rupture or urinary tract obstruction
• Severe abdominal infections (peritonitis)
• Trauma (being hit by a car, a fall, stab or bite wounds)

Symptoms of an acute abdomen

• Severe abdominal pain (whining, guarding the abdomen, refusing to move)
• Lethargy and collapse
• Rapid breathing and heart rate
• Vomiting and/or diarrhea
• Enlarged, tense abdomen
• Signs of shock: pale mucous membranes, low body temperature, weak pulse

Diagnosing an acute abdomen

The diagnosis is made using a combination of clinical examination and further diagnostics:

• Physical examination: abdominal palpation, pain response
• Blood tests: inflammatory markers, organ function, clotting
• Ultrasound: assessment of abdominal organs and free fluid
• X-rays: detecting obstructions, perforations, or gas buildup
• Abdominal puncture: detecting free blood or pus in the abdomen

Emergency surgical procedures

An acute abdomen often requires immediate surgery. Possible procedures include:

• Gastric surgery for torsion (gastropexy)
• Enterotomy or enterectomy for intestinal obstruction or perforation
• Splenectomy for splenic bleeding
• Ovariohysterectomy for pyometra
• Bladder surgery for rupture or obstruction
• Cleaning of the abdominal cavity for peritonitis

The goal is always life-saving intervention and stabilization of the animal.

Aftercare and recovery

An acute abdomen often requires intensive aftercare. At Nesto's practices, we are fully equipped to professionally support and closely monitor your pet during this recovery period, so it can recover as comfortably and safely as possible.

Prognosis

The prognosis for acute abdominal surgery depends heavily on how quickly treatment is provided and on the underlying cause. The sooner surgery is performed, the greater the chance of a full recovery. With delayed treatment, the risk of life-threatening complications increases considerably.
