To study the clinical effects of a disposable circumcision device in treatment of male patients of different ages with either phimosis or excess foreskin.
One thousand two hundred patients between the age of 5 and 95 years underwent circumcision using this procedure in the 2-year period between October 2005 and September 2007. Of these cases, 904 had excess foreskin and 296 were cases of phimosis.
In 96.33% of the cases the incision healed, leaving a minimal amount of the inner foreskin with no scarring and producing good cosmetic results. There were no incidents of device dislocation or damage to the frenulum. The average operative time was 2.5 min for excess foreskin, and 3.5 min for phimosis. During the 7 days of wearing the device, mild to moderate edema occurred in 10.08% of cases with excess foreskin and in 2.58% of those with phimosis. Edema in the frenulum was seen in 1.67% of patients, and only 0.67% had an infection of the incision. A total of 86.25% of patients reported pain due to penile erection. After removal of the device, 0.58% of the cases had minimal bleeding around the incision, and 2.42% had wound dehiscence.
The new device can be applied to an overwhelming majority of patients with phimosis and excess foreskin. This technique is relatively simple to perform, and patients who underwent this surgery had very few complications. Antibiotics were not required and patients reported less pain than those who were circumcised using conventional methods. Circumcision with this device requires minimal tissue manipulation, and is quicker and safer than circumcision using conventional techniques.

    • "If not, it would be removed by a surgeon 21 days after the operation. Group II used the ShD with the method first introduced by Peng in 2008. 10 Briefly, the inner ring was placed on the outer layer of the foreskin (over the glans). "

    ABSTRACT: Objectives: To compare the outcomes and complications of three methods of circumcision in a Chinese pediatric population. Methods: A total of 120 children were randomly assigned to three groups. Group I was submitted to circumcision using the Shenghuan disposable device according to Yan's method; group II was submitted to circumcision using the same device, but according to Peng's methods; group III was operated on by using the conventional scalpel/suture technique. The three groups were compared mainly by the following outcomes: duration of surgery, intraoperative bleeding, postoperative pain, cosmetic effect, and the rates of edema, dehiscence, scarring, adhesion and infection. Results: Groups I and II had less intraoperative bleeding. In terms of the duration of surgery, group I was the quickest. Pain scores in using the Shenghuan disposable device were higher at 6 h after surgery compared with the conventional scalpel/suture technique. The percentage of patients using paracetamol in group II was higher than that in group III at 12 h after surgery. Other complications were similar, and all three groups had successful outcomes. Conclusions: Circumcision using the Shenghuan disposable device represents a safer and time-saving option compared with the conventional scalpel/suture technique, with better cosmetic outcomes. Yan's method seems to be better than Peng's method when using the Shenghuan disposable device for circumcision in children.

    • "Preliminary data are also becoming available on devices that could facilitate quicker and safer adult circumcision [178]. These include the Shang Ring [179] (which produced good results for safety and acceptability in a field test in Kenya [180]), circumcision template [181], the recently acclaimed PrePex system [182], and the Tara KLamp [183], for which further assessment is needed [178] after adverse effects were initially reported [184]. In an important development, WHO has provided a framework for clinical evaluation of devices for adult MC [185], in addition to those already recommended for infant MC [144]. "

    ABSTRACT: Heterosexual exposure accounts for most HIV transmission in sub-Saharan Africa, and this mode, as a proportion of new infections, is escalating globally. The scientific evidence accumulated over more than 20 years shows that among the strategies advocated during this period for HIV prevention, male circumcision is one of, if not, the most efficacious epidemiologically, as well as cost-wise. Despite this, and recommendation of the procedure by global policy makers, national implementation has been slow. Additionally, some are not convinced of the protective effect of male circumcision and there are also reports, unsupported by evidence, that non-sex-related drivers play a major role in HIV transmission in sub-Saharan Africa. Here, we provide a critical evaluation of the state of the current evidence for male circumcision in reducing HIV infection in light of established transmission drivers, provide an update on programmes now in place in this region, and explain why policies based on established scientific evidence should be prioritized. We conclude that the evidence supports the need to accelerate the implementation of medical male circumcision programmes for HIV prevention in generalized heterosexual epidemics, as well as in countering the growing heterosexual transmission in countries where HIV prevalence is presently low.
