ObjectiveTo assess the feasibility and safety of laparoscopic liver resections. Summary Background DataThe use of the laparoscopic approach for liver resections has remained limited for technical reasons. Progress in laparoscopic procedures and the development of dedicated technology have made it possible to consider laparoscopic resection in selected patients. MethodsA prospective study of laparoscopic liver resections was undertaken in patients with preoperative diagnoses including benign lesion, hepatocellular carcinoma with compensated cirrhosis, and metastasis of noncolorectal origin. Hepatic involvement had to be limited and located in the left or peripheral right segments (segments 2-6), and the tumor had to be 5 cm or smaller. Surgical technique included CO 2 pneumoperitoneum and liver transection with a harmonic scalpel, with or without portal triad clamping or hepatic vein control. Portal pedicles and large hepatic veins were stapled. Resected specimens were placed in a bag and removed through a separate incision, without fragmentation.
