Hepatectomy is a crucial surgical method for treating liver diseases such as liver cancer, hepatic hemangiomas, and biliary stones. Although hepatectomy has achieved significant therapeutic effects, postoperative complications remain an inevitable issue. Complications following hepatectomy include liver failure, hepatic vascular thrombosis, wound infection at the hepatic incision, and bile leakage, among others. These complications pose a serious threat to patients' health and life, and also increase the waste of medical resources and the cost of treatment. Currently, research on postoperative complications of hepatectomy mainly focuses on small sample studies from a single center, and most studies only focus on a specific complication, lacking comprehensive and systematic analysis. Therefore, it is necessary to conduct a retrospective study analysis of complications related to hepatectomy to more comprehensively and objectively understand the incidence, risk factors, prevention, and treatment of postoperative complications, providing clinical doctors with more scientific treatment plans and guidance.

To ensure the protection of patients' clinical information data, ethical committee approval is required before sharing data with other research studies. This process is crucial for maintaining patient confidentiality and adhering to privacy regulations and ethical standards in research.
