Objective:To evaluate the laparoscopic sleeve gastrectomy combined with hiatal hernia repair surgery for weight loss and antireflux.Methods:This study included 21 obese patients with gastroesophageal reflux who underwent laparoscopic sleeve gastrectomy at the Weight Loss Metabolism Center of the Department of Hepatobiliary and Pancreatic Surgery of Zhejiang Provincial People's Hospital from Dec 2019 to Dec 2020. Patients were divided into simple bariatric surgery group (9 cases) and simultaneous combined surgery group (12 cases).Results:In the combined surgery group, 1 case had postoperative gastric leakage. The postoperative body weight, waist circumference, and BMI indexes of the two groups showed a downward trend ( F=5.154, P=0.013; F=14.319, P<0.001; F=6.725, P=0.004). There was a statistically significant difference in the excess weight loss in both the two groups at 6 months after the operation compared to 1 month after the operation ( t=8.927, P<0.001; t=8.926, P<0.001). There was no statistically significant difference in postoperative lower esophageal sphincter resting pressure and Gerd symptom score in the bariatric surgery group compared with preoperative ( t=-0.891, P=0.507; t=0.629, P=0.298). The postoperative Gerd symptom score of the patients in the combined surgery group was significantly lower than that before the operation, and the resting pressure of the lower esophageal sphincter was significantly higher than that before the operation, ( t=-10.539, P<0.001; t=5.066, P=0.038). Conclusion:Combined surgery have the same weight loss effect as in simple bariatric surgery in obese patients with gastroesophageal reflux, in addition to stronger anti-reflux effect.

Objective:To explore the research status, hotspots, and trends of bariatric surgery nursing at home and abroad, and gain insights from foreign research, so as to provide reference and guidance for the domestic bariatric surgery nursing.Methods:China National Knowledge Infrastructure, WanFang Data, VIP, and Web of Science Core Collection were analyzed using with CiteSpace 6.2.R4 software. "Bariatric Surgery" and approximate nouns were used as search terms in both Chinese and English. The search period was from database establishment to April 1, 2023. After screening the literature, the investigators conducted analysis on the distribution and trend of publications, cooperation network of publishing countries, network of publishing institutions, and distribution of publishing journals. Keywords were analyzed for co-occurrence, clustering, and emergence, and clustering labels were extracted to form a clustering time zone map.Results:After screening, 401 English articles and 161 Chinese articles were ultimately obtained. Postoperative continuing nursing was a common research hotspot both domestically and internationally, including dietary compliance and psychological status. Foreign countries also paid attention to fields such as pain nursing and pathological obesity. The overall trend of research was multidisciplinary, refined, and intelligent. The number and quality of publications were both increasing.Conclusions:Domestic investigators can learn from foreign experiences, improve existing research on bariatric surgery, and fully leverage the advantages of interdisciplinary cooperation to effectively improve the quality of bariatric surgery nursing and the quality of life in obesity patients.

Objective:To evaluate the application status of wearable smart devices in domestic and foreign medical fields through visual analysis.Method:With “smart wearable device” “wearable smart device” “Smart wearable device” and “wearable smart devices” as search terms, literatures on the application status of wearable intelligent devices in the medical field at home and abroad in the core collection of CNKI, Wanfang, VIP, PubMed and Web of Science databases were retrieved from the establishment of the databases to April 30, 2023. The software CiteSpace was used for bibliometric analysis, including publication trend, institutional cooperation network, publication journal distribution analysis, keyword co-occurrence, clustering and emergence analysis, as well as publication journal and literature co-citation analysis.Results:A total of 121 valid Chinese literatures and 289 English literatures were obtained. Domestic and foreign research began in 2013 and 2004, respectively, and the overall number of published papers showed an upward trend. The top 3 institutions of publication in China were Chinese Academy of Sciences (13 articles), Union Hospital Affiliated to Huazhong University of Science and Technology (11 articles), and West China Nursing College of Sichuan University (10 articles). The top 3 institutions in the number of foreign publications were Harvard University (13 articles), the University of California (14 articles), and the University of London (5 articles). The top 3 Chinese journals in terms of publication volume were Nursing Research, Journal of Nursing Science and Chinese Journal of Nursing, with 38 publications, accounted for 31.4% of the total publications. The top 3 foreign journals in terms of publication volume are Sensors, IEEE Access and Applied Sciences-Basel, with a total of 39 publications, accounted for 13.5% of the total publications. A total of 8 Chinese keyword clusters and 10 English keyword clusters were formed. The top 5 categories were “senior citizens” “artificial intelligence” “mobile medical” “extended care” “nursing” and “wearable electronics” “sensor” “deep learning” “mobile health” and “big data”; there were 9 emergent words in Chinese and 10 emergent words in English. The top 5 were “wearable” “internet of things” “review literature” “big data” “smart watch” and “care” “activity recognition” “wearable sensors” “system” and “accelerometer”. The journal with the highest total citation frequency was Sensors, and the journal with the highest total citation center was Biosens. Bioelectron.. There were 2 literatures with a total citation frequency of 11-20 times, and 10 literatures with a frequency of 5-10 times. Conclusions:The research popularity of wearable smart devices in the medical field is generally increasing, and the quantity and quality of English papers are higher than those of Chinese. At present, mobile health is mainly used in the fields of physical signs monitoring, pain assessment, rehabilitation and exercise. Mobile health is a common research hotspot at home and abroad.
