Laparoscopic Liver Resection

The indications for laparoscopic liver resection in Israel are similar to those for open surgery. In other words, if a patient is not eligible for open surgery, they are also not eligible for a laparoscopic procedure. This applies to surgeries on other organs as well.

Liver resection in Israel is performed to remove part of the liver affected by a benign or malignant tumor.

Thanks to the liver’s remarkable ability to regenerate, up to 70% of liver tissue can be removed without causing irreversible damage or serious consequences for the patient.

Benign tumors are typically removed only if they cause significant symptoms (such as pressure on adjacent structures due to large size) or if there’s a risk of malignant transformation, as is the case with certain adenomas.

Malignant tumors can be either primary (originating in the liver tissue, like hepatocellular carcinoma or cholangiocarcinoma) or secondary (metastatic tumors from colorectal cancer or cancers in other organs).

The liver is divided into 8 segments. Tumors located in the more superficial segments (segments 2, 3, part of 4, 5, and 6) are ideal for laparoscopic liver resection. However, more extensive procedures — such as right or left lobe segmental liver resection — can also be performed using minimally invasive techniques.

Typically, tumors less than 5–7 cm in size are considered suitable for laparoscopic liver tumor removal in Israel.

The operation is done under general anesthesia. At any point, the surgeon may decide to convert the procedure to open surgery if necessary.

After anesthesia is administered, the surgeon makes several small incisions (usually 4–5) in the upper abdomen and inserts hollow tubes called trocars. Carbon dioxide is used to inflate the abdomen for better visibility and maneuverability.

A laparoscope equipped with a camera is inserted through one of the ports, allowing the surgeon to view the liver and surrounding organs on a screen. Intraoperative ultrasound helps map the tumor and its relation to blood vessels and bile ducts.

After removing the tumor, the surgeon ensures there is no bleeding or bile leakage. The incisions are closed using absorbable sutures.

Following liver surgery in Israel, the patient is taken to a recovery room to gradually wake from anesthesia. They are then transferred to a surgical ward for further monitoring. In most cases, hospitalization lasts between 1 to 3 days depending on the extent of the procedure and individual recovery speed.

Recovery after laparoscopic liver surgery in Israel is generally faster than after traditional open surgery. However, it remains a complex surgical procedure with associated risks.

During the initial days, patients typically rest and gradually resume normal activities such as eating, walking, and personal hygiene. Once stable, they are discharged and continue recovery at home under outpatient supervision.

A follow-up appointment will be scheduled to review healing progress and discuss the pathology results of the removed liver tissue.

The pace of recovery depends on the extent of the resection. For small and moderate liver resections, recovery usually takes a few days in the hospital followed by a quick return to normal life.

In cases of major liver resection for cancer, recovery is slower and includes a regeneration phase where the liver gradually restores itself over 6 to 8 weeks. During this time, patients may experience fatigue.

For the first 6–8 weeks, it’s recommended to avoid physical exertion and sexual activity. If fatigue or dizziness occurs, patients should refrain from driving. The surgical area should be kept clean and washed with soap and water twice daily.

About one month after surgery, a follow-up consultation is held with the surgeon. If fever exceeds 38°C, or if any complications arise, the patient should contact the hospital immediately or go to the emergency room.
