Robotic ALPPS

Background The associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) procedure is a useful strategy to treat patients with advanced liver tumors and small future liver remnants. This video presents a robotic ALPPS procedure to treat synchronous colorectal liver metastases. Methods A 71-year-old man with liver metastases from sigmoid cancer was referred. A multidisciplinary team decided on chemotherapy followed by liver resection (first), then colon resection. After four cycles, objective response was observed and the multidisciplinary team then chose the ALPPS procedure. The future liver remnant (segments 3 and 4 and the Spiegel lobe) was 24%. A robotic approach was proposed. Colon resection was performed after the ALPPS procedure, also using the robotic approach. Results The duration of the first stage was 293 min, and the technique used in the first stage was partial ALPPS (parenchymal transection deep to 2 cm above the inferior vena cava) with preservation of the right hepatic duct. The patient was discharged on the fourth day. The second stage of the procedure took 245 min. Recovery was uneventful and the patient was discharged on the fourth day. Finally, the patient underwent robotic resection of the primary colorectal neoplasm. The surgery lasted 182 min, recovery was uneventful, and the patient was discharged on the fifth postoperative day. Final pathology disclosed a T3N1bM1 adenocarcinoma. Liver pathology confirmed colorectal metastases with partial response. All surgical margins were free. Currently, the patient is well, with no signs of disease 5 months post-procedure. Conclusions Robotic ALPPS is feasible and safe. The robotic approach may have some advantages over the laparoscopic and open ALPPS approaches. This video may help oncological surgeons to perform this complex procedure.
