The Effectiveness of a Clinical Pathway in Liver Surgery: a Case-Control Study.

Background: In the field of liver surgery, evidence on the effectiveness of clinical pathways based on ERAS principles is limited.

Methods: This is a single-center observational study from a prospectively maintained database. Two cohorts were formed of all patients undergoing liver surgery during a defined period before (traditional management) and after introduction of a clinical pathway.

Laparoscopic versus open parenchymal preserving liver resections in the posterosuperior segments: a case-matched study.

Background: Patients with lesions in the posterosuperior (PS) segments of the liver have been considered poor candidates for laparoscopic liver resection (LLR). This study aims to compare short-term outcomes of LLR and open liver resections (OLR) in the PS segments.

Methods: This multicenter study consisted of all patients who underwent LLR in the PS segments and all patients who underwent OLR in the PS segments between October 2011 and July 2016.
