Surgical resection for benign and malignant liver disease

Area of Science:

• Hepatobiliary Surgery
• Surgical Oncology
• Gastroenterology

Background:

• Major hepatic resections are performed for various liver conditions, including primary and metastatic cancers, hemangiomas, and benign lesions.
• The study reviews a series of 32 patients undergoing major hepatic resections to evaluate outcomes.

Purpose of the Study:

• To present the indications and outcomes of major hepatic resections in a cohort of 32 patients.
• To analyze complication rates, operative mortality, and long-term survival following liver resection.

Main Methods:

• Retrospective review of 32 patients who underwent major hepatic resections.
• Analysis of surgical procedures performed, including right lobectomies, left lobectomies, and extended resections.
• Categorization of resected lesions into primary liver cancers, metastatic lesions, hemangiomas, and benign lesions.

Main Results:

• A total of 32 major hepatic resections were performed, with varying types of lobectomies.
• The overall complication rate was 46%, and the operative mortality rate was 12.5%.
• Survival rates were encouraging for hepatomas (4/7 alive at 24 months), metastatic lesions (6/11 alive at 27 months), and hemangiomas (4/4 alive at 7 years).
• Operative mortality decreased significantly from 42% pre-1970 to 4% post-1970, but complication rates in survivors remained high (25-50%).

Conclusions:

• Cautious patient selection for liver resection, particularly for malignant tumors, can lead to extended survival.
• Despite advancements reducing operative mortality, complication rates in survivors of major hepatic resections remain a challenge.
• The study supports the role of hepatic resection in managing selected liver malignancies and benign conditions.
