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.
