Abstract
A 50–years–old woman was admitted to another hospital with exacerbating epigastralgia and abdominal bloating. In April 2008, a liver cyst was discovered on abdominal CT. In April 2010, she was admitted to our hospital for worsening abdominal symptoms. The liver cyst had enlarged to 10 cm in diameter and a gallstone was identified with abdominal CT and ultrasonography. The patient was treated with one–stage liver cyst fenestration and cholecystectomy via single–incision laparoscopic surgery. The operation time was 147 minutes (75 minutes for liver fenestration and 72 minutes for cholecystectomy). Blood loss was minimal. The patient was discharged on the third day after the operation.
