Objective:To reveal the global evolution, cooperation models and research hotspots of wounds with drug-resistant bacterial infections in the elderly, and provide information support for future research directions.Methods:All literatures on wounds with drug-resistant bacterial infections in the elderly were retrieved from the Web of Science Core Collection. Bibliometric analysis was performed using CiteSpace and VOSviewer to visualize contributions from countries/regions, institutions, authors and journals, and to analyze keyword co-occurrence and temporal evolution.Results:After strict screening, a total of 130 literatures were included. Global research achievements on wounds with drug-resistant bacterial infections in the elderly showed a continuous growth. The United States was the main contributor in terms of the number of literatures, followed by Spain, Germany and the United Kingdom. However, international cooperation was still limited, and the institutional network was sparse. The most significant burst keywords at present included " risk factors", " methicillin-resistant", " inpatients", " molecular epidemiology", " Staphylococcus aureus", " long-term care facilities", " nosocomial infections", " mortality", " pressure ulcers", " complex wounds" and " emerging drug-resistant bacteria" .Conclusions:In the future, priority must be given to in-depth research on the pathogenesis of wounds with drug-resistant bacterial infections in the elderly (epidemiological investigation of drug-resistant bacterial infections in elderly patients, interaction between single cells of aging wounds and drug-resistant microbiome); verification of the mode and effect of stratified precise treatment through multi-country trials; and establishment of a professional database through data collection and multi-modal information integration.

Objective:To investigate the application value of ambulatory surgery mode in inguinal hernia repair.Methods:The retrospective and descriptive study was conducted. The clinical data of 416 patients with inguinal hernia who were admitted to the Meishan People′s Hospital, West China Hospital of Sichuan University from January 2020 to January 2022 were collected. There were 374 males and 42 females, aged 52(range, 25-70)years. All patients underwent inguinal hernia repair with the ambulatory surgery mode. Observation indicators: (1) surgical situations; (2) follow-up. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1) Surgical situations. Of the 416 patients, 258 patients underwent laparoscopic transabdominal preperitoneal inguinal hernia repair (TAPP) under general anesthesia and 158 patients underwent open inguinal hernia repair under local anesthesia (98 cases of Lichtenstein repair and 60 cases of preperitoneal repair). The intraoperative measured diameter of hernia ring defect and operation time of the 416 patients were 1.9 (range, 0.9-3.2)cm and 52 (range, 35-80)minutes. The duration of hospital stay of the 416 patients <48 hours, including 395 cases with the duration of hospital stay <24 hours. There were 21 patients with delayed discharge including 12 cases as post-operative pain, 8 cases as adverse reactions to general anesthesia, and 1 case as postoperative seroma. (2) Follow-up. All 416 patients were followed up for 12 months after surgery. During the follow-up period, there was no serious complication such as recurrent inguinal hernia, wound infection, intestinal fistula or obstruction. At 1 month after surgery, ultrasound examination of the inguinal area did not reveal any serum swelling or seroma. The postoperative visual analogue scale of pain in patients undergoing laparoscopic TAPP was 2.70±0.10 at postoperative 3 days and 0 at postoperative 12 months. The above indicator in patients undergoing Lichtenstein repair and pre-peritoneal repair was from 3.20±0.20 and 3.00±0.10 at postoperative 3 days to 0 and 0 at post-operative 12 months, respectively. All patients did not experience chronic pain for more than 3 months. All 416 patients conducted satisfaction surveys over the phone, and all of them were very satisfied or satisfied, with a satisfaction rate as 100.00%(416/416).Conclusion:Ambulatory surgery mode in inguinal hernia repair is safe and feasible.
