Reports laparoscopic deroofing of liver cysts have drawn our attention recently. A laparoscopic approach has advantages as minimal access surgery, but has the possibility of causing complications by hemorrhage and bile leakage. In this paper, we described three surgical cases of symptomatic giant liver cysts. In case 1, hemorrhage occurred when we resected the cyst wall by electrocautery with the aid of a laparoscope. Therefore, in case 2, we resected the cyst wall with an endoscopic stapling device (ENDO GIA) for complete hemostasis and control of bile duct, because the peritoneal surface of the cyst was overlaid by thin parenchymal tissue. In case 3, we resected the cyst wall with laparoscopic coagulating shears (LCS), because the peritoneal surface of the cyst was mainly extrahepatic. This device reduces the risk of hemorrhage and damage to the liver. These patients were asymptomatic after operation and developed no signs of recurrence. We suggest that the laparoscopic deroofing of liver cysts with these devices, a simple, safe procedure, may become a primary method of treating symptomatic liver cysts.
