研究概览
简要总结
The purpose of this study is to evaluate the Shang Ring, a novel Chinese device for voluntary medical male circumcision, in order to improve the provision of male circumcision services for HIV prevention in Africa.
详细描述
Three randomized clinical trials (RCTs) have confirmed the benefit of voluntary medical male circumcision (VMMC) in reducing the acquisition of HIV by circumcised men. In Africa, VMMC is most commonly performed with the methods described in the WHO Manual for Male Circumcision under Local Anaesthesia (i.e., the forceps-guided, dorsal slit or sleeve method).
Modelers have estimated that to scale-up VMMC to prevent large numbers of HIV infections will require millions of circumcisions over the next 5 to 10 years, with more than 10 million circumcisions in 2012 based on aggressive scale-up plans.
Neonatal circumcision is a very common procedure and has been the subject of numerous clinical trials. With the use of simple devices, neonatal circumcision is rapid and safe. In contrast, current adult surgical techniques are done freehand. Adolescent or adult male medical circumcision has been a rarely performed procedure in most developed countries. Circumcision has suffered from little or no research that could make possible either (a) comparison or simplification of surgical techniques or (b) development of devices to facilitate the procedure. Current techniques are time consuming and require long training periods to produce skilled personnel. Each procedure typically takes 20 to 40 minutes.
A search for more efficient adult circumcision techniques has been undertaken by consultants for the World Health Organization (WHO) and the Bill & Melinda Gates Foundation. Preliminary discussions that helped to produce this proposal suggest that the Shang Ring is one of the most promising existing devices that could greatly simplify adult circumcision. More efficient and simpler techniques could potentially:
- Reduce the operating time and the cost of supplies
- Improve the safety of the procedure
- Permit more rapid training of non-physician health care providers
- Accelerate the process of scaling up this proven HIV prevention strategy
