[Progress in the clinical studies of male circumcision using the Shang Ring].

Male circumcision can reduce men's risk of HIV infection from heterosexual intercourse by 60% and is therefore recommended as an important strategy for HIV prevention in Africa by WHO and UNAIDS. However, rapid expansion of male circumcision efforts could be greatly facilitated by a safer, more effective and acceptable male circumcision surgical technique or device. Shang Ring is a simple technique developed in China. It allows a circumcision to be completed with minimal bleeding, without suturing, and in only 3-5 min and reported complications are few. A standardized adult male circumcision surgical protocol utilizing the Shang Ring device was developed in 2008 in China. Several surgical training courses using this protocol were successfully held in 2009 and 2010 in China. A recent pilot clinical study of the Shang Ring was conducted to evaluate its safety and efficiency in Kenya in 2009. The results and acceptability among study participants were excellent and confirmed many of the advantages seen in the earlier Chinese studies from Wuhu, Ningbo and Xi'an, suggesting that the Shang Ring is safe for further studies in Africa, thus, could facilitate more rapid roll-out of adult male circumcision through task shifting, surgical efficiencies and better acceptability. Further international investigations of the Shang Ring technique have now been planned for Kenya and Zambia in 2011. Moreover, adult male circumcision utilizing the Shang Ring device is now being considered as ope of the potential candidate techniques to be used in the scale-up of adult male circumcision services for HIV prevention in WHO priority countries in Africa. This review article summarizes Shang Ring related clinical studies, seminars and surgical workshops, publications and presentations conducted between February 2008 and December 2010 in China, the United States and Africa.
