What type of liver resection is performed for segment 1+2?

In the context of liver anatomy and surgical procedures, segment 1 refers to the caudate lobe, while segments 2 and 3 correspond to parts of the left hepatic lobe. A resection that involves segments 1 and 2 would typically require a left hepatic lobectomy because the left hepatic lobe encompasses segments 2 and 3, and segment 1, the caudate lobe, can be resected simultaneously with a left lobectomy to ensure complete removal of diseased tissue.

When performing a left hepatic lobectomy, the surgeon removes not only the left lobe but also addresses any concerns related to the caudate lobe. This type of resection is crucial when treating specific conditions such as hepatocellular carcinoma or metastases in those segments.

The other options, like a right hepatic lobectomy or a middle hepatic lobectomy, involve resecting different parts of the liver that do not include segments 1 and 2. A right hepatic lobectomy removes the right lobe, which comprises segments 5, 6, 7, and 8, while a middle hepatic lobectomy would focus on the central parts of the liver, again excluding the caudate lobe and segments
