An observational study in Hepatocellular Carcinoma, Hepatectomy and Laparoscopic Hepatectomy, sponsored by West China Hospital. Recruiting at 1 site in China. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-04-30.

Although traditional open right hemihepatectomy is a mature technique, the incision is usually very large; Intraoperative bleeding may be excessive, and postoperative liver failure is also prone to occur. In recent years, compared with traditional open surgery, laparoscopic surgery has many advantages, such as smaller surgical incision and faster postoperative recovery. In recent years, more and more centers have gradually transitioned to performing right hemihepatectomy through laparoscopy as much as possible. However, due to the difficulty of the surgery, steep learning curve, and postoperative complications, its adoption is limited to high-capacity surgical centers. Despite significant progress in laparoscopic liver resection technology, its clinical efficacy remains controversial, especially in laparoscopic right hemihepatectomy. More research is needed to confirm the feasibility and safety of this surgery. At present, it is unclear whether there is a difference in textbook outcomes (TO) between HCC patients undergoing open and laparoscopic right hemihepatectomy, and the association between TO and patient survival prognosis.
6,741 studies on the registry are indexed under Carcinoma; 1,161 are open to participants now.

The data was collected from patients who underwent right hemihepatectomy and were diagnosed with HCC pathologically. The data was collected from the division of Liver Surgery of West China Hospital, SCU from January 2018 to January 2023.
Exclusion Criteria:
Procedure: laparoscopic right hemihepatectomy
Laparoscopic surgery has many advantages, such as small surgical incision and fast postoperative recovery. In recent years, more and more centers have gradually transitioned to performing right hemihepatectomy through laparoscopy as much as possible.
Textbook outcome
Textbook outcome (TO) was defined as the absence of intraoperative grade ≥ 2 incidents (defined according to the Oslo classification), postoperative bile leak of grade B or C (according to the severity grading of the International Study Group of Liver Surgery), postoperative liver failure grade B or C (according to the severity grading of the International Study Group of Liver Surgery), major postoperative complications within 90 days (Clavien-Dindo grade III or higher), readmission within 90 days after discharge due to surgery related major complications (Clavien-dindo Grade III or higher), in-hospital or 90-day mortality and the presence of R0 resection margin (i.e. 1mm or more tumor free margin).
Time frame: From January 2018 to January 2023
Overall survival
Overall survival (OS) was defined as the interval from liver resection to death or the last follow-up.
Time frame: From January 2018 to January 2023
Disease-free survival
Disease-free survival (DFS) was defined as the time from liver resection to disease recurrence or death from any cause.
Time frame: From January 2018 to January 2023
