Trial summary
Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is a procedure used for patients with initially unresectable colorectal liver metastases (CRLM). However, the procedure has been reported to be associated with high morbidity and mortality. Read more about this study

About this study
Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is a procedure used for patients with initially unresectable colorectal liver metastases (CRLM). However, the procedure has been reported to be associated with high morbidity and mortality. Laparoscopic ALPPS has recently been reported as a minimally invasive technique that reduces perioperative risks. This study aimed to assess the safety and feasibility of full laparoscopic ALPPS in patients with CRLM.

What does the primary outcome measure?
Incidence of Adverse Events (time frame: within the first 90 days after the first stage of ALPPS). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Apr 2025; AzTrials last refreshed its copy on 8 Nov 2026.
