What is a Segmentectomy of the liver?
What is a Segmentectomy of the liver?
Abstract. Segmentectomy is anatomical resection of segments based on the classification of Couinaud. This procedure is performed mainly for hepatocellular carcinoma. Invasion of portal vein and intrahepatic metastases often occur with hepatocellular carcinoma.
Can the caudate lobe be removed?
Caudate lobe resections, although technically challenging, can be successfully performed with minimal blood loss. Surgery offers potential cure in isolated caudate lobe tumors.
When is Pringle maneuver used?
The Pringle manoeuvre is used during liver surgery to minimize blood loss. For short durations of use, it is very effective at reducing intraoperative blood loss. The Pringle manoeuvre is applied during closure of a vena cava injury when an atriocaval shunt is placed.
Which lobe is in the liver?
The human liver is divided grossly into four parts or lobes. The four lobes are the right lobe, the left lobe, the caudate lobe, and the quadrate lobe….

What is Segment 5 of the liver?
segment 5 (V) is located below the portal plane between the middle and right hepatic veins. segment 6 (VI) is located below the portal plane to the right of the right hepatic vein. segment 7 (VII) is located above the portal plane to the right of the right hepatic vein.
What is caudate resection?
Isolated resection of the caudate lobe involves three major points: (1) control of the inflow supply from the portal vein and hepatic artery; (2) dissection, ligature, and division of the retrohepatic veins; and (3) parenchymal section to divide and remove the tumor from the base of other liver segments.
What is right upper lobectomy?
A lobectomy is a surgery to remove one of the lobes of the lungs. The lungs have sections called lobes. The right lung has 3 lobes. The left lung has 2 lobes. A lobectomy may be done when a problem is found in just part of a lung.
What is the function of caudate lobe?
The caudate lobe (segment I) is the autonomous zone of the liver. It receives portal venous, as well as hepatic arterial, blood from both branches of the aforementioned vessels. Additionally, its biliary drainage is by both branches of the hepatic ducts and its venous return goes directly into the inferior vena cava.
What is Calot’s triangle?
Calot triangle or cystohepatic triangle is a small (potential) triangular space at the porta hepatis of surgical importance as it is dissected during cholecystectomy. Its contents, the cystic artery and cystic duct must be identified before ligation and division to avoid intraoperative injury.
How long can you do Pringle maneuver?
Conclusion The upper limit of tolerance of the liver to intermittent Pringle maneuver is 120 minutes.
