Hepatic neoplasms: surgically relevant segmental anatomy and imaging techniques

Area of Science:

• Hepatobiliary Surgery
• Diagnostic Imaging
• Surgical Oncology

Background:

• Recent advancements in imaging and surgical techniques have significantly improved the diagnosis and treatment of liver neoplasms.
• Improved imaging allows for earlier tumor detection, precise characterization, and localization of liver lesions.
• Surgical techniques have evolved, enabling more extensive liver resections, underscoring the need for accurate preoperative imaging.

Purpose of the Study:

• To discuss the segmental anatomy of the liver.
• To outline various types of liver segmental resections.
• To evaluate the strengths and weaknesses of imaging techniques for preoperative assessment of liver resection candidates.

Main Methods:

• Review of liver segmental anatomy.
• Analysis of different liver segmental resection techniques.
• Evaluation of imaging modalities for preoperative liver tumor assessment.

Main Results:

• Precise definition of tumor extent relative to hepatic segmental anatomy is essential for presurgical planning.
• Different imaging techniques offer varying strengths and weaknesses in characterizing liver lesions.
• Understanding segmental anatomy guides the selection of appropriate resection types.

Conclusions:

• Accurate preoperative imaging and a thorough understanding of liver segmental anatomy are vital for successful liver resection.
• The choice of imaging modality should be tailored to the specific clinical scenario for optimal presurgical planning.
• Advances in surgical techniques necessitate corresponding advancements in imaging for effective liver neoplasm management.
