Abstract    Objective    To analyze the papers，research hotspots and research trends in the research field of laparoscopic hepatectomy，so as to provide references for relevant personnel in this field to carry out the academic research of laparoscopic hepatectomy.  Methods    In the web of Science（WOS），take " laparoscopic liver resection " as the subject word, "August 20，2021" as the time node，and "paper or review" as the source to limit the type of journals. Use Excel to sort out the retrieved documents，and get the basic overview of the annual number of documents，countries or regions，periodicals，institutions and authors. Use CiteSpace to perform keyword cluster analysis，and obtain the research hotspot and development trend. Results    A total of 2792 articles were retrieved，the total number of publications was small,  but the annual publication volume showed an increasing trend. Literature sources were highly concentrated in a few countries or regions. More than 100 articles in this field were published by 3 journals. More than 100 documents issued by 3 issuing institutions. More than 50 articles issued by 10 people. The research hotspots in this field focused on radiofrequency ablation，liver surgery，cholecystectomy，liver transferase and surgical management. From the evolution trend of research topics from 2002 to 2021，partial hepatectomy，ultrasonography，cancer cells，malignant tumors，liver tumors，laparoscopic cholecystectomy，bile duct injury，radiofrequency ablation of liver metastasis，surgical management，diagnostic laparoscopy，single center，meta-analysis and outcm are the frontier topics in this field，it may become the focus of scholars' attention in the next few years. Conclusion    Laparoscopic hepatectomy has been widely used all over the world because of its advantages of small trauma and rapid recovery. In the future，it is necessary to pay attention to the cutting-edge research in this field and explore new surgical methods on the existing basis.
