title: Feasibility of laparoscopic liver resection for giant hemangioma of greater than 6 cm in diameter.
abstract: OBJECTIVE
  Liver hemangioma, the most common benign liver tumor, can be safely managed by clinical observation. However, surgical treatment should be considered in a subset of patients with giant hemangioma with abdominal symptoms. We reviewed the feasibility of total laparoscopic liver resection for giant hemangioma of >6 cm in diameter.
  
  
  METHODS
  Nine consecutive patients who underwent total laparoscopic liver resection for giant hemangioma between August 2008 to December 2012 were included in this study. Medical records were retrospectively reviewed for demographic data, laboratory findings, and perioperative results.
  
  
  RESULTS
  The median age of patients was 36 yrs (range, 31-63). Eight females and 1 male were included in the study. The median size of hemangioma was 11 cm in diameter (range, 6-18) and 5 patients had a hemangioma >10 cm. Indications for surgical treatments were abdominal symptoms in 4 patients, increased size in 5 patients, and uncertain diagnosis in 1 patient. The median operation time was 522 minutes for right hepatectomy, 220 minutes for left lateral sectionectomy, and 90 minutes for wedge resection. The median estimated blood loss was 400 ml (range, 50-900). There was no postoperative morbidity, including Clanvien-Dindo grade I.
  
  
  CONCLUSIONS
  The resection of giant hemangioma demands meticulous surgical technique due to high vascularity and the concomitant risk of intraoperative hemorrhage. Laparoscopic liver resection is feasible with minimal operative complication. Therefore, laparoscopic liver resection can be considered as an option for surgical treatment for giant hemangioma.
