Selective use of diagnostic laparoscopy prior to planned hepatectomy for patients with hepatocellular carcinoma.

BACKGROUND

Patients with hepatocellular carcinoma (HCC) are frequently found to be inoperable at surgical exploration. Laparoscopy may reduce the rate of unnecessary laparotomy in these patients. However, there are no criteria for selective use of laparoscopy.

METHODS

Sixty patients with potentially operable HCC underwent laparoscopy prior to planned partial hepatectomy. Intraoperative findings and postoperative course were analyzed, and factors for the selective use of laparoscopy were identified.

RESULTS

Fourteen of 19 inoperable patients (74%) were identified by means of laparoscopy, which increased the resectability rate from 68% to 89%. Compared with patients undergoing exploratory laparotomy only, patients determined to be inoperable on laparoscopy had significantly less intraoperative blood loss, a shorter operating room time, and a briefer hospital stay. In a multivariate analysis, clinically apparent liver cirrhosis and radiologic evidence of major vascular invasion or bilobar tumors predicted the likelihood of finding inoperable disease at laparoscopy. The initial use of laparoscopy avoided unnecessary laparotomy in almost 30% of patients with-but only 5% of patients without-these features.

CONCLUSIONS

If high-risk patients with HCC are selectively targeted, the yield of laparoscopy is increased and unnecessary laparotomy may be avoided. In patients without cirrhosis, major vascular invasion, or bilobar tumors, the yield of laparoscopy is low and is therefore not generally recommended.
