Objective To investigate the current status of esophageal cancer surgery-related researches using bibliometric methodologies and identify the trend and hotspots. Methods The Chinese and English literature was collected from Web of Science and CNKI from inception of each database to April 1, 2022. VOSviewer 1.6.18 and CiteSpace 6.1 were applied to cluster the authors, institutions, and keywords. For social network and time series analysis, Excel, GraphPad, and R 4.0.3 were used to visualize the literature on esophageal cancer surgery. Results Finally, 19 566 English literature and 19 872 Chinese literature was included. The results demonstrated that the annual publishing of both Chinese and English literature increased over time, with English literature increasing rapidly and Chinese literature maintaining an average number of above 1 000 per year from 2011 to 2019. Researches were predominantly centered in Europe, the United States, Japan, South Korea, and China. China's researches in the field of surgical treatment in esophageal cancer lacked international collaboration, which began later than East Asian countries such as Japan and South Korea and had less influence. From the keyword perspective, previous researches on surgical treatment of esophageal cancer mostly focused on surgical techniques, complications, and comprehensive perioperative therapy. Both Chinese and English literature showed that the prevalence of keywords such as minimally invasive surgery, comprehensive treatment, and clinical trials increased dramatically during the recent years, indicating that these fields may represent the future directions and research trends. Conclusion Compared to East Asia countries, such as Japan and South Korea, Chinese esophageal cancer surgery-related researches are relatively lacking. The research direction and field are similar to those in developed countries such as the United States and Europe. Future attention may be focused on minimally invasive treatment, comprehensive treatment, and clinical trials associated with surgical treatment of esophageal cancer.
Objective To analyze the major complications and predictive factors of amputees during postoperative hospitalization, and provide a reference for amputees nursing and early rehabilitation. Methods Using the bibliometric method, we searched Embase, Ovid, Medline, PubMed, CINAHL, China National Knowledge Infrastructure, Wanfang and CQVIP databases for the data of postoperative hospitalization of amputees published from January 1st, 2008 to April 5th, 2022. Statistical description and analysis of article types, sample size, reasons for amputation, amputation sites, complications, influencing factors, predictive factors, and treatment recommendations were performed.Results Finally, 19 articles were included, including 16 in English and 3 in Chinese, all of which were quantitative studies. The literature quality scores were greater than or equal to 7 points, which were all good or excellent. The type of articles were mainly retrospective research (n=15), and the research contents were mainly lower limb amputation. The main reasons for amputation were peripheral vascular disease and diabetes mellitus (n=11). Wound infection, anemia, phantom limb pain, and psychological problems were common complications after amputation. Predictors of complications, secondary operations, and death included age, gender, smoking, drinking, obesity, preoperative comorbidities, level of amputation, anesthesia methods and other factors. Conclusions The focus of acute care after amputation should be wound healing, pain control, proximal physical movement and emotional support, especially for amputees who have prominent postoperative psychological problems. These patients need early psychological disease screening and mental support. After amputation, multi-disciplinary and multi-team coordinated care are needed to achieve both physical and psychological healing of the patient and promote early recovery.
