Background/Purpose:
We draw on our experience with laparoscopic hepatectomy (LH) to present recommendations for standardization of LH for the treatment of liver tumors.
Methods:
At our center, 90 LHs were performed from April 1993 to January 2008. These were divided equally into early cases and late cases, and short-term postoperative results were compared. Forty-nine of the LH procedures were total-laparoscopic procedures, 16 were hand-assisted procedures, and 25 were laparoscopy-assisted procedures. The tumors were malignant in 76 cases and benign in 14 cases.
Results:
Among late cases, the numbers of malignant tumors and tumors located in the posterosuperior region of the liver (Segments VII, VIII, and IVb) were significantly higher than among early cases; however, operative blood loss and postoperative hospital stay were significantly lower in the late cases (158.9 +/- 213.4 vs. 377.6 +/- 421.2 cc, P = 0.007; and 8.7 +/- 3.6 vs. 15.3 +/- 8.7 days, P = 0.0001, respectively). No operative deaths occurred in either group.
Conclusions:
Although LH does have a steep learning curve, we believe that it can be standardized and provide a less invasive surgical option--with no reduction in disease curability--for the treatment of liver tumors in selected patients.
