title: Isolated caudate lobe resection for hepatic tumor: surgical approaches and perioperative outcomes.
abstract: BACKGROUND
  Caudate lobe of the liver is relatively inaccessible because of its deep location and lying between the major vascular structures. Therefore, isolated caudate lobe resection (ICLR) is a much challengeable operation.
  
  
  METHODS
  Review of prospectively collected data from patients who underwent ICLR for hepatic tumor.
  
  
  RESULTS
  Forty-six patients (mean age 46.8 years) underwent ICLR for malignant (39 cases) and benign (7 cases) hepatic tumors. ICLRs were performed by 3 different approaches and in different ways of hepatic vascular control: without any vascular control in 7 patients, under Pringle maneuver in 26 patients, and under sequential inflow and outflow vascular occlusion in 13 patients. There were no perioperative deaths, and the postoperative complication rate was 8.7% (4/46). The mean operative time was 174.5 +/- 44.3 minutes and the mean estimated intraoperative blood loss was 504.4 +/- 356.2 mL.
  
  
  CONCLUSIONS
  ICLR is a technically demanding but safe procedure. Choice of surgical approaches and ways of hepatic vascular control should be based on tumor location and surgeons'experience.
