| 1 | Areas of research and clinical approaches to the study of liver abscess显示文摘AIM To analyze the research activity on liver abscess(LA) and identify the main topic clusters in the area. METHODS We identified all documents using the medical subject heading 'LA' indexed in the MEDLINE database between 2001 and 2015. We performed a descriptive bibliometric analysis, characterizing the evolution of scientific activity, the publication types of the documents, the document categories of clinical interest(case reports, clinical trials, evaluation studies, meta-analysis, observational studies, practice guidelines and validation studies) and the geographic distribution of the research. We also carried out an analysis of networks and research clusters in order to identify the main topic areas of research.RESULTS Our search yielded a total of 1278 documents, showing a stable scientific production over the study period and a marked multidisciplinary nature. The research was dominated by case reports(65.9% of the documents analyzed). In terms of geographic distribution, researchers from the United States led in the number of signatures(n = 229), followed by those from Taiwan(n= 185), India(n = 145), Japan(n = 144), South Korea(n = 100), and China(n = 84). With regard to amebic LA, the top-producing countries were India and Mexico(n = 69 each), followed by the United States(n = 29). In the case of pyogenic LA, Taiwan Residents researchers led scientific production(n = 71), followed by the United States(n = 39) and China(n = 29). The most active areas of research in the field are diagnosis via computerized tomography scan, differential diagnosis with regard to liver cancer, treatment with antimicrobial agents, and Klebsiella infections(including bacteremia).CONCLUSION Clinical case reports associated with diagnosis and treatment are the main topic of study, highlighting the importance of this document type in advancing knowledge. | Gregorio González-Alcaide Jorge Peris José Manuel Ramos | 2017 | World Journal of Gastroenterology2017，23，2： | 3 |
