HYPOTHESIS: Robotic surgery for performance of right hepatectomy is safe and effective. DESIGN: Case series from 2 medical institutions. SETTING: University of Illinois at Chicago and Misericordia Hospital, Grosseto, Italy. PATIENTS: Twenty-four patients underwent right hepatectomy between March 1, 2005, and January 31, 2010, using a robotic surgical system. MAIN OUTCOME MEASURES: Intraoperative blood loss, operative time, morbidity, mortality, and long-term oncologic follow-up. RESULTS: The procedure was converted to open surgery in 1 patient (4.2%). The overall mean (SD) operative time was 337 (65) minutes (range, 240-480 minutes), and the mean (SD) intraoperative blood loss was 457 (401) mL (range, 100-2000 mL). Three patients (12.5%) underwent blood transfusion. There were no perioperative deaths and no reoperations. Six patients (25.0%) experienced postoperative morbidity, including transitory liver failure in 2 patients and pleural effusion, bile leak, fluid collection, and deep venous thrombosis in 1 patient each. The patients' diagnoses included colorectal liver metastases (n = 11), noncolorectal liver metastases (n = 4), hemangioma (n = 4), adenoma (n = 2), hepatocellular carcinoma (n = 1), hepatoblastoma (n = 1), and biliary amartoma (n = 1). At a mean follow-up duration of 34 months, no port site metastases were observed in patients with malignant pathologic findings. CONCLUSIONS: The zero mortality and acceptable morbidity of our series indicate that in experienced hands, robotic right hepatectomy is feasible and safe. Robotic surgery offers a new technical option for minimally invasive major hepatic resections. Long-term results seem to confirm oncologic effectiveness of the procedure.
