Parenchymal-sparing Hepatectomy in Colorectal Liver Metastasis Improves Salvageability and Survival

Objective: To investigate prognostic impact of parenchymal-sparing hepatectomy (PSH) for solitary small colorectal liver metastasis (CLM). Background: It is unclear whether PSH confers an oncologic benefit through increased salvageability or is a detriment through increasing recurrence rate. Methods: Database of 300 CLM patients with a solitary tumor (≤30 mm in size) was reviewed from 1993 to 2013. A total of 156 patients underwent PSH and 144...
