BackgroundAssociating liver partition with portal vein ligation for staged hepatectomy (ALPPS) represents a new surgical technique for the resection of advanced hepatic malignancies with predicted insufficient future liver remnant. In some patients, ALPPS can be associated with an increased risk of poor outcomes. Minimally invasive surgery (MIS) has been proposed in combination with ALPPS with the intent to minimize this risk. We systematically evaluated the outcomes of MIS-ALPPS cases to compare the relative outcomes of open ALPPS versus MIS-ALPPS.MethodsA systematic review was done in accordance with the PRISMA guidelines. Search terms utilized included the following: (“ALPPS”[Title/Abstract] OR “associating liver partition and portal vein ligation for staged hepatectomy”[Title/Abstract] OR “in situ split”[Title/Abstract]) AND (“minimally invasive”[Title/Abstract] OR “laparoscopic”[Title/Abstract] OR “robotic”[Title/Abstract]).ResultsFifteen articles were identified, with a total of 27 patients reported. Colorectal metastatic disease was the most commonly observed indication for MIS-ALPPS (66.7%), followed by hepatocellular carcinoma (25.9%). Time passed from the first to the second stage ranged 7–30 days. MIS-ALPPS patients did not experience procedure failures between the first and second stages. Only four (15.4%) subjects had a grade IIIb complication. No perioperative mortality after the first or second stage was reported. Compared with open ALPPS, MIS-ALPPS demonstrated better results. Hospital stay duration ranged 8–33 days with a follow-up ranging 1–20 months.ConclusionsMIS-ALPPS appears to be safe, with potentially lower morbidities and mortalities relative to open patients. The present results should be considered with caution. A limited number of articles exist on this topic. Furthermore, selection biases exist when comparing open versus MIS-ALPPS data. Registry studies are needed to better define the outcomes of patients undergoing MIS-ALPPS.
