Brief Summary:
Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is a new surgical procedure that induces rapid liver regeneration in patients with small liver remnant planning for major liver resection. It is a two-staged operation with stage I including portal vein ligation and splitting the right liver away from the left liver. After stage I, the left liver will undergo rapid liver regeneration and the stage II operation can be performed at 7-10 days after stage I operation when the liver remnant reaches an adequate size. In stage II operation, the right liver that contains the tumor is then removed. This surgical procedure was incepted in Germany in 2013 and was later started in Queen Mary Hospital in Hong Kong for the first time in December 2015. The initial indication was mainly for colorectal liver metastasis but due to the relatively high incidence of hepatocellular carcinoma in Hong Kong, HBP surgery team of Queen Mary Hospital has transferred this procedure to be applied for hepatitis-related hepatocellular carcinoma and so far, the centre has cumulated one of the largest single-center experience in the literature. Nonetheless, the usual approach for ALPPS involved open surgery and induced substantial surgical stress to the patient, especially after stage I operation. With the advent of minimally invasive liver surgery in recent years, the team has successfully applied laparoscopic surgery to ALPPS in 2019. Despite the advancement in laparoscopic surgical skills that rendered laparoscopic ALPPS feasible, there is scarcity of data in the literature to evaluate its outcome in comparison with open ALPPS with regard to perioperative recovery and liver regeneration. Hence, the aim of this project is to evaluate the short-term clinical outcomes of laparoscopic ALPPS and the impact of laparoscopy on liver remnant regeneration after ALPPS in a prospective randomised clinical trial setting.

Liver Cancer Procedure: Associating Liver Partition and Portal Vein Ligation for Staged Hepatectomy (ALPPS) Not Applicable

Detailed Description:

Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) has been popularized as an alternative approach for FLR augmentation in recent years. The main indication at the early phase of development of this procedure was bilobar colorectal liver metastasis, or other non-primary liver tumors. Since 2015, HBP surgery team of Queen Mary Hospital has started to transfer this novel approach to treat patients with hepatitis-related hepatocellular carcinoma and small future liver remnant contemplating for major hepatectomy. Despite the initial global enthusiasm to embark on ALPPS, the procedure was criticized for its high postoperative morbidity and mortality rates. However, through the establishment of the international ALPPS registry and familiarization of the procedure, the outcome of ALPPS has been benchmarked and standardized with a mortality rate <4%. The initial experience of ALPPS for HCC was also reported. With cumulative experience, ALPPS has become a safe and effective treatment approach for surgical modulation of insufficient FLR when compared with the conventional approach in the form of portal vein embolization. Nonetheless, ALPPS is a two-stage procedure that commonly involved an open laparotomy. However, the postoperative pain control and speed of recovery after stage I ALPPS would be affected by the substantial surgical stress induced by laparotomy. On the other hand, the rapid development of laparoscopic surgery has rendered laparoscopic liver surgery a much more feasible and safer surgical approach in recent years. As such, minimally invasive approach becomes an attractive option for ALPPS, at least for stage I procedure. Data on the application of laparoscopic ALPPS remained scarce with only one study reported the short-term outcome in a series of 10 patients predominantly affected by colorectal liver metastasis.

Since the short-term postoperative safety profile and underlying intraoperative haemodynamic changes induced by ALPPS for hepatitis-related HCC under conventional open approach was ascertained by our recent study, it is considered that it is the right time to introduce laparoscopy for ALPPS and to compare its clinical outcome with open approach. To date, a total of 4 patients have received laparoscopic ALPPS in the centre.

Recent studies suggested that laparoscopic liver resection may be associated with reduced inflammatory and stress response as compared with open resection as indicated by a reduced expression of inflammatory cytokines such as interleukin-6, tumor necrosis factor. On the other hand, study on liver regeneration after open ALPPS showed an elevated gene expression of IL-6 and TNF as well as increased plasma levels within 24 hours after the procedure when compared with portal vein ligation. It remains uncertain if reduced level of cytokines or inflammatory markers induced by laparoscopy would affect the liver regeneration rate in ALPPS patients and its clinical outcome. Hence, there is a need to clarify this issue in the current project.
