Liver surgery: What to expect, risks, and recovery

Liver surgery, or hepatic surgery, includes several types of procedures performed to remove diseased tissue, treat tumors, repair injury, or manage advanced liver conditions. Common operations include liver resection, in which a portion of the liver is removed; ablation therapies that destroy abnormal tissue using heat, cold, or chemical methods; and liver transplantation, which replaces a failing liver with a healthy donor organ. Minimally invasive techniques, such as laparoscopic or robotic approaches, may be used when suitable, often allowing for faster recovery.

These operations are performed for a variety of indications. Liver surgery may be recommended for primary liver cancers like hepatocellular carcinoma or cholangiocarcinoma for metastatic tumours that have spread from other organs, for benign but or premalignant symptomatic liver growths or traumatic injuries.

As with any major abdominal procedure, liver surgery involves potential risks. Bleeding is a notable concern because the liver is a highly vascular organ, and other risks include infection, bile leakage, blood clots, hernias, and complications from anaesthesia.

To reduce these risks, surgeons rely on detailed imaging to plan the operation, use advanced techniques that minimise blood loss, optimize liver function beforehand, and closely monitor patients during and after the procedure. Patients are also guided on lifestyle measures, such as improving nutrition and stopping smoking, which help support safer outcomes.

Before surgery, individuals typically undergo blood tests, imaging scans, and an anesthesia evaluation. Medication adjustments and fasting instructions are provided in advance. After surgery, patients spend time in a monitored setting, receive pain control, gradually resume eating, and are encouraged to walk early to prevent complications. Fatigue and mild discomfort are common during healing.

The length of hospital stay varies, usually ranging from three to seven days for the most common operations or longer for more extensive ones, with full recovery taking several weeks. With minimally invasive options, length of stay can be as quick as 1 or 2 days.

Due to the intricate liver anatomy and physiology, as well as the complexities of the surgical treatment along with the high peri-operative risks, these operations are performed only by specialist HPB Surgeons. Identifying and selecting a surgeon with substantial experience is highly recommended
