Aim: We reviewed a retrospectively collected database of 64 patients undergoing two-stage hepatectomy for colorectal liver metastases with special attention to cases involving a laparoscopic first stage. Materials and methods: Three patients undergoing laparoscopic first-stage hepatectomy were analyzed and compared with 61 other patients who underwent two-stage hepatectomy using open surgery for the first stage. Results: In three patients with a laparoscopic approach, the first-stage operation was a laparoscopic lateral sectionectomy or resection of segment 3, combined with portal vein embolization via the iliac vein directed at the contralateral hemiliver. No postoperative morbidity or mortality resulted. After a mean interval of 37.3 days, second-stage hepatectomy was performed for clearance of tumors in the right hemiliver (two in an open approach and one in a hybrid laparoscopic and open approach), with morbidity in 67% of patients (Clavien–Dindo classes I and IIIb in one patient each) but no mortality. When these three patients were compared with 61 patients treated with an open approach, numbers of metastatic tumors tended to be less in patients with a laparoscopic first stage. Duration of the first-stage hepatectomy (p <0.01) and hospital stay after that hepatectomy were shorter in patients with laparoscopic resection than in patients with open resection (p = 0.03). Conclusion: Our preliminary data support the feasibility and safety of the laparoscopic approach for the first-stage resection during two-stage hepatectomy. Clinical significance: First-stage laparoscopic clearance for patients with relatively small numbers of tumors who are anticipating two-stage hepatectomy for bilobar metastases becomes a standard option.
