  • Chlorhexidine versus povidone iodine for preventing surgical site infections: a meta-analysis

    Objective To systematically review the efficacy of chlorhexidine versus povidone iodine in the prevention of wound infections after surgeries by meta-analysis. Methods All randomized controlled trials comparing these two disinfectants were searched from databases of PubMed, The Cochrane Library (Issue 3, 2016), EMbase, WanFang Data, VIP and CNKI from inception to August 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.2 software. Results A total of 14 randomized controlled trials were included. The results of meta-analysis showed that the chlorhexidine group had significantly lower rates in any surgical site infection (RR=0.71, 95% CI 0.58 to 0.88,P=0.001) and superficial incisional infection (RR=0.66, 95% CI 0.48 to 0.91,P=0.01) when compared with povidone iodine group. However, there were no significant differences in deep incisional infection (RR=0.51, 95% CI 0.23 to 1.11,P=0.09) and organ-space infection (RR=0.97, 95% CI 0.53 to 1.76,P=0.92) between the two groups. Furthermore, subgroup analysis revealed differences in any surgical site infection and superficial incisional infection could only be found in surgeries possibly contaminated. Conclusion Chlorhexidine may be superior in decreasing the incidence of infection in probably contaminated surgery.

  • Tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device in anterior mediastinal masses

    Objective To assess the clinical value of a novel surgical technique——Tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device in the resection of anterior mediastinal masses. Methods Patients who underwent tubeless subxiphoid uniportal video-assisted thoracoscopic surgery via balance-shaped sternal elevation device in anterior mediastinal masses process at the Department of Thoracic Surgery, West China Hospital, Sichuan University from March to April 2025 were included, and their clinical data were analyzed. Results A total of 4 patients were included, with 2 males and 2 females, aged 58-75 years. The diameter of the tumor was 2.5-3.0 cm. The operation time was 60-150 min, intraoperative blood loss was 5-10 mL, pain score on the 3rd day after surgery was 0 points, and postoperative hospital stay was 2-3 days. All patients achieved complete resection of the masses and thymus without perioperative complications. ConclusionThe tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device technique optimizes surgical visualization and instrument maneuverability while avoiding complications related to conventional anesthesia and tubing, thereby markedly enhancing the minimally invasive profile of anterior mediastinal masses resections. In addition to maintaining procedural safety, this approach effectively reduces postoperative pain and accelerates patient recovery, highlighting its potential for widespread clinical adoption.
