Clinical Challenges in Hepatobiliary Surgery: Bilateral Colorectal Liver Metastasis

Surgical resection of bilateral colorectal liver metastasis (CLM) can pose a significant challenge to even the most experienced HPB surgeon. Is surgical resection justified, if so, in which patients? What’s the best surgical approach for curative intent resection of all lesions, and does ablation play a role? In this episode from the HPB team at Behind the Knife, listen in on the discussion about the surgical management of patients with bilateral colorectal liver metastasis. Hosts Anish J. Jain MD (@anishjayjain) is a T32 Research Fellow at the University of Texas MD Anderson Cancer Center within the Department of Surgical Oncology. Timothy E. Newhook MD, FACS (@timnewhook19) is an Assistant Professor within the Department of Surgical Oncology. He is also the associate program director of the HPB fellowship at the University of Texas MD Anderson Cancer Center. Jean-Nicolas Vauthey MD, FACS (@VautheyMD) is Professor of Surgery and Chief of the HPB Section, as well as the Dallas/Fort Worth Living Legend Chair of Cancer Research in the Department of Surgical Oncology at The University of Texas MD Anderson Cancer Center Learning Objectives: · Develop an understanding of patient selection for surgical resection of bilateral colorectal liver metastasis (CLM). · Develop an understanding of the use of Two Stage Hepatectomy (TSH) versus Parenchymal Sparing Hepatectomy (PSH) in the treatment of bilateral CLM. · Develop an understanding of if and when to use ablative procedures for resection of bilateral CLM. · Develop an understanding of selection and management of patients who suffer recurrence after resection of bilateral CLM.
