What is a right hepatectomy?

Right hepatectomy is a well-standardized procedure consisting of resection of liver parenchyma on the right side of Cantlie’s line in the right side of the MHV (see Fig. 108B. 4). The inclusion of the MHV corresponds to an extended right hepatectomy.

What is a partial hepatectomy?

Partial hepatectomy is surgery to remove part of the liver. Only people with good liver function who are healthy enough for surgery and who have a single tumor that has not grown into blood vessels can have this operation.

What organ is removed in a hepatectomy?

A liver resection is the surgical removal of all or a portion of the liver. It is also referred to as a hepatectomy, full or partial. A complete liver resection is performed in the setting of a transplant a diseased liver is removed from a deceased donor (cadaver).

Which are the segments of the right lobe of the liver?

The functional right lobe of the liver is made up of segments V and VIII, the anterior segments, and segments VI and VII, the posterior segments. Segment I, the caudate lobe, is located posteriorly. The outflow of the liver is provided by the three hepatic veins.

How do you do a right hepatectomy?

The conventional method for right hepatectomy is complete mobilization of right liver, control of vascular inflow and outflow of the part of liver to be resected, followed by parenchymal transection. This approach can be difficult and s]ometimes dangerous for large tumors in the right liver [1].

What is major hepatectomy?

A major hepatectomy should be defined as resection of four or more liver segments.

What can I expect after a partial hepatectomy?

You will spend 5–10 days in hospital after a partial hepatectomy, and up to three weeks in hospital following a transplant. If you have a laparoscopy, the recovery time is shorter – you may be able to return to your usual activities within a week. Drips and drains are removed before you leave hospital.

How long is a partial hepatectomy?

The surgery can take anywhere between two and four hours.

How is a hepatectomy done?

A hepatectomy is considered a major surgery done under general anesthesia. Access is accomplished by laparotomy, typically by a bilateral subcostal (“chevron”) incision, possibly with midline extension (Calne or “Mercedes-Benz” incision).

What is the normal size of the right lobe of the liver?

Pfahler (1), in a recent study of liver measurements, demonstrated the average length of the right lobe to be 21.3 cm. and the average thickness 12.8 cm.

Why is the liver divided into segments?

Couinaud classification. The Couinaud classification of liver anatomy divides the liver into eight functionally indepedent segments. Each segment has its own vascular inflow, outflow and biliary drainage. In the centre of each segment there is a branch of the portal vein, hepatic artery and bile duct.

What is lateral hepatectomy?

Laparoscopic left lateral hepatectomy (LLLH) is a standardized and anatomically well-defined resection and may transform into a primarily laparoscopic procedure for cancer surgery or living donor hepatectomy for transplantation.
