title: Surgical treatments in cystic diseases of the liver: experience at a single center in Japan.
abstract: OBJECTIVE
  Benign cystic diseases of the liver have recently been treated by non-surgical procedures; however, uncontrolled symptomatic patients often need surgical treatment. We report here our own experience of 5 patients with cystic liver diseases (CLD).
  
  
  METHODS
  We examined retrospectively the clinicopathological findings and outcome in 5 CLD patients who underwent surgical treatment for 12 years.
  
  
  RESULTS
  All patients complained of symptoms and the mean period of symptoms was 3.8 years. Two patients had perforation of cystic content. Three patients had multiple cysts in both lobes and 2 showed a solitary cyst. The mean cyst size was 13.2cm. Communication between cyst and bile duct was observed in 1 patient. Liver scintigraphy was good compared to the higher value of ICGR15 in 3 patients. Deroofing was performed in 3 patients including laparoscopic treatment and 2 underwent hemihepatectomy. The mean amount of the cystic fluid was 1560mL. All patients had benign liver cysts by histologic findings. One patient had a biloma after deroofing which was percutaneously drained and cured. Although liver cyst recurred in 2 patients, all patients have survived without severe symptoms.
  
  
  CONCLUSIONS
  Surgical radical treatment provides good prognosis in CLD patients with uncontrolled symptoms.
