Objective To summarize the history, status quo, and prospect of robotic surgery system in domestic department of hepatobiliary surgery. Methods Related papers published in many databases, such as CNKI, VIP, WanFang, PubMed, an so on, were collected to make a review. Results With the development by nearly 8 years in our country, robotic surgery system has been preliminary used in all kinds of complicated operation in domestic department of hepatobiliary surgery, and positive results has been achieved. Currently robotic surgery technique is still in the continuous improvement and innovation. With the progression of robotic surgery technique and development of related equipment, this system would be more widely applied in domestic department of hepatobiliary surgery. Conclusions Robotic surgery system is now in the stage of development and promotion, but robotic surgery system has its unique advantages and it also has great development potential in technology. We believe that the robotic surgery system will be widely used in department of hepatobiliary surgery.
ObjectiveTo understand the authors, countries/regions, institutions, journals and hot topics about the application research of indocyanine green (ICG) in hepatobiliary surgery. MethodsThis study conducted a bibliometric analysis of the literatures on the application of ICG in hepatobiliary surgery in the Web of Science Core Collection from 2008 to 2024. CiteSpace software was used to evaluate and visualize collaborative networks and hot topics. ResultsA total of 2 267 literatures were included in this study, with a citation frequency of 50 463 times. The literatures from Japan accounted for the highest proportion, and most of the papers (13.50%) were published by Kokudo N. In China, Tian Jie had published the largest number of papers (33 articles). The research hotspots focused on liver resection, bile duct surgery, liver transplantation, and tumors, with recent hotspots including “liver preservation” and “rejection” frequently appearing. ConclusionThis study aims to present the overall state and trend of the application research of ICG in hepatobiliary surgery through data capture and induction, and providing valuable references for clinicians and researchers.
ObjectiveTo preliminarily explore application and effectiveness of real-scene teaching based on a live demonstration system in hepatobiliary surgical training, using laparoscopic cholecystectomy (LC) as an example. MethodsFrom March 2023 to February 2024, 60 surgical residents undergoing a 4-month standardized residency training at the Liver Transplant Center of West China Hospital, Sichuan University, were randomly assigned into an observation group (n=30) and a control group (n=30) using a random number table. The observation group received real-scene surgical teaching based on the live demonstration system, while the control group received traditional teaching methods. At the end of the training, both groups underwent an operative assessment on LC and completed a resident satisfaction questionnaire. Operative assessment used critical view of safety (CVS) scoring to evaluate surgical safety. Resident satisfaction was assessed using a self-designed questionnaire covering five domains: stimulating the learning atmosphere, increasing learning engagement, improving surgical proficiency, enhancing the understanding of surgical complications, and recognition of the teaching model. The final results were categorized as positive or negative evaluations. The significance level was set at α=0.05. ResultsThe observation group had significantly higher CVS score than the control group [4.2±1.3 vs. (2.8±1.7), t=3.57, P=0.001]. All 60 questionnaires were collected, and the observation group reported significantly higher positive evaluations in improving surgical proficiency, enhancing the understanding of surgical complications, and recognition of the teaching model compared to the control group (P<0.05). There were no statistically significant differences between the two groups regarding positive evaluations for stimulating the learning atmosphere and increasing learning engagement (P>0.05). ConclusionThe results of this study suggest that the real-scene teaching model based on a live demonstration system demonstrates good effectiveness in hepatobiliary surgical training and can improve the quality of surgical teaching during standardized residency training for surgical residents.
