Randomized controlled trial of the shang ring versus conventional surgical techniques for adult male circumcision: safety and acceptability

Wound healing rates and wound problems of conventional circumcision compared with ring circumcision: A meta-analysis

A meta-analysis investigation was executed to measure the wound healing rates (WHRs) and wound problems (WPs) of conventional circumcision (CC) compared with ring circumcision (RC). A comprehensive literature investigation till March 2023 was applied and 2347 interrelated investigations were reviewed. The 16 chosen investigations enclosed 25 838 individuals, with circumcision, were in the chosen investigations' starting point, 3252 of them were RC, and 2586 were CC. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were used to compute the value of the WHRs and WPs of CC compared with RC by the dichotomous or continuous approaches and a fixed or random model. RC had a significantly lower wound infection rate (WIR) (OR, 0.58; 95% CI, 0.37-0.91, P = .002) and wound bleeding rate (WBR) (OR, 0.22; 95% CI, 0.12-0.42, P < .001) compared with those with CC. However, RC and CC had no significant difference in WHR (OR, 2.18; 95% CI, -0.73 to 5.09, P = .14), wound edema rate (WER) (OR, 1.11; 95% CI, 0.92-1.33, P = .28), and wound dehiscence rate (WDR) (OR, 0.98; 95% CI, 0.60-1.58, P = .93). RC had significantly lower WIR, and WBR, however, no significant difference in WHR, WER, and WDR compared with those with CC. However, care must be exercised when dealing with its values because of the low sample size of some of the nominated investigations for the meta-analysis.

Systematic review: Safety of surgical male circumcision in context of HIV prevention public health programmes

Background: Since the recommendation of voluntary medical male circumcision (VMMC) to reduce the risk of heterosexually acquired HIV, a number of adolescent boys and men in 15 priority countries in Africa have been circumcised. Our primary goal was to identify the incidence of adverse events (AEs) associated with VMMC and to assess the safety profile among adolescent boys 10 - 14 years. Methods: We searched the databases MEDLINE and Embase, WHO, and conference abstracts from 2005 to 2019. The incidence of AEs was estimated by type of AE, size of study and age. Results: We retained 40 studies. Severe and moderate AEs overall were estimated at 0.30 per 100 VMMC clients with wide variability per study type. A higher rate was noted in small and moderate scale programmes and device method research studies compared with larger scale programmes. There was a limited number of studies reporting AEs among younger adolescent boys and they had higher infection-related AEs than those aged 20 years and older. Case studies noted rare AEs such as necrotizing fasciitis, tetanus, and glans injury. Conclusions: AE rates were comparable to those from the randomized controlled trials (RCTs) that led to recommendations and implementation of VMMC in high HIV burden countries, despite being implemented in low resource settings. Clients over time have increasingly included adolescents under the age of 15 years. Studies suggest potentially higher risks in this age group. As VMMC services are sustained, patient safety surveillance systems and promoting a patient safety culture are crucial to identify and mitigate potential harms from medical male circumcision.

VMMC Programmatic Successes and Challenges: Western Kenya Case Study

PURPOSE OF REVIEW

The Nyanza region of western Kenya is lauded for impressive coverage of voluntary medical male circumcision (VMMC) and remains the bedrock of the VMMC program in Kenya. We conducted literature review on programmatic successes and challenges of implementing VMMC program in the region.

RECENT FINDINGS

Responsive stakeholders' engagement, robust policy environment, effective technical working groups, prompt capacity building of health facilities, government support, flexible implementation strategies, and sustained donor funding contributed to the successes of the program that saw circumcision prevalence in Nyanza reach between 75.6 and 85.3% among 15-29-year-olds by 2019. However, the lack of support for early infant circumcision, inadequate domestic financing, and slow pace of service integration into government health facilities continue to undermine the progress towards sustainability. While local ownership of the VMMC program has been demonstrated through its inclusion in county annual health workplans and progressive integration into routine health care, continued dependence on declining external funding threatens its sustainability. Furthermore, Kenya is experiencing a youth bulge with a projected high demand for VMMC which calls for increased resource inputs into the program. Strategies are therefore needed to increase domestic resource inflows into VMMC.

Comparison of ring instruments and classic circumcision methods: a systematic review and meta-analysis

Aim

To determine the advantages and disadvantages of both methods by comparing classic circumcision methods with circumcision methods assisted by ring instruments.

Material-Methods

Only studies that compared open procedures and ring devices for male circumcision were included. A total of 6226 patients were examined in 14 studies. The methodological quality of RCT was evaluated using Cochrane collaboration’s tools. The Review Manager software statistical package was used to analyze the ORs for dichotomous variables and the mean differences for continuous variables. The proportion of heterogeneity across the studies was tested using the I 2 index. Potential publication bias was assessed by identifying the presence of visual asymmetry/symmetry with funnel plot studies.

Results

There were 1812 patients in the open circumcision group and 4414 patients in the ring groups. In total, there was no difference identified between the groups. The open procedure had an advantage compared to the Plastibell subgroup for hemorrhage, while in the other two subgroups, the ring instrument groups had the advantage. Statistically significant in favor of ring devices was found in operating time.There was no difference between the groups for early (postoperative) pain scores. For late-period pain scores, differences with statistical significance were identified in favor of ring devices both in subgroups and in total. For satisfaction, apart from one study in the PrePex group, statistical significance was obtained in favor of ring devices for the other subgroups and in total.

Conclusion

The main factors in favor of the use of ring instruments for circumcision are the short total surgical duration, not requiring advanced surgical experience, ease of learning and application, and patient relative satisfaction rates. However, it is a condition to know open circumcision methods and to have experience of this surgery for use in situations with hemorrhage complications, mainly, and without ring instruments of appropriate size.

Circumcision devices versus standard surgical techniques in adolescent and adult male circumcisions: a Cochrane review

OBJECTIVES

To assess the effects of device-based circumcisions compared with standard surgical techniques in adolescent and adult males (10 years old and above).

METHODS

We performed a comprehensive search with no restrictions to the language of publication or publication status. We included randomised controlled trials (RCTs) of device-based circumcisions compared to standard surgical dissection-based circumcision conducted by health professionals in a medical setting. We reported study results as risk ratios (RRs) or mean differences (MDs) using 95% confidence intervals (CIs) and a random-effects model. We used the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach to evaluate the overall certainty of the evidence for each outcome.

RESULTS

A total of 18 trials met the inclusion criteria. These trials did not report severe adverse events (AEs; 11 trials, 3472 participants). There may be a slight increase in moderate AEs for devices compared to surgical techniques (RR 1.31, 95% CI 0.55-3.10; I²  = 68%; 10 trials, 3370 participants; low-certainty evidence); this corresponds to eight more (ranging from 15 fewer to 84 more) moderate AEs per 1000 participants. We are uncertain about the difference in mild AEs between groups when devices are used compared to surgical techniques (RR 1.09, 95% CI 0.44-2.72; I²  = 91%; 10 trials, 3370 participants; very low-certainty evidence).

CONCLUSIONS

We found no serious AEs using a circumcision device compared to surgical techniques. Still, they may slightly increase moderate AEs, and it is unclear whether there is a difference in mild AEs. High-quality trials evaluating this intervention are needed to provide further certainty regarding the rates of AEs. Clinicians, patients, and policymakers can use these results combined with their contextual factors to inform the best approach that suits their healthcare settings.

Genitourinary Infections Related to Circumcision and the Potential Impact on Male Infertility

Male circumcision (MC) is one of the oldest surgical procedures still completed today. Medical indications for MC include phimosis, recurrent balanitis, cosmesis, and infection prevention. In this review, we mainly focus on the role of MC in the prevention of human immunodeficiency virus, human papillomavirus, herpes simplex virus, gonorrhea, chlamydia, chancroid, and syphilis, and the subsequent impact of these genitourinary infections on male fertility. Overall, many compelling data support that MC may play an essential role in both genitourinary infection prevention and male fertility.

Circumcision devices versus standard surgical techniques in adolescent and adult male circumcisions

BACKGROUND

Medical circumcisions are among the most common surgical procedures performed in males. The usual indications are phimosis (inability to completely retract the foreskin and expose the glans due to a congenital or acquired constriction of the prepuce), paraphimosis (when the foreskin is not pulled back over the glans after retraction resulting in a tight constricting band which causes swelling of the distal penis and acute discomfort), balanoposthitis (erythema and edema of the prepuce and glans) and balanitis (inflammation is confined to the glans; the foreskin is usually non-retractile). Circumcision devices have been developed to shorten the operative time, simplify techniques, and improve safety and cosmetic outcomes. The devices generally aim to crush the foreskin while simultaneously creating hemostasis, the foreskin is then excised or allowed to slough off. Their use is supposedly safer and easier to replicate than the standard dissection techniques. There are at least 20 devices for male circumcision on the market, yet their effectiveness has not been reviewed to date.

OBJECTIVES

To assess the effects of device-based circumcisions compared with standard surgical techniques in adolescent and adult males (10 years old and above).

SEARCH METHODS

We performed a comprehensive search with no restrictions to the language of publication or publication status. We searched the Cochrane Library, MEDLINE (PubMed), Embase, Web of Science, trials registries, grey literature sources and conference proceedings up to 16 April 2020.

SELECTION CRITERIA

We included randomized controlled trials of device-based circumcisions (crush or ligature circumcision devices) compared to standard surgical dissection-based circumcision conducted by health professionals in a medical setting.

DATA COLLECTION AND ANALYSIS

At least two review authors independently assessed study eligibility and extracted data from the included studies. We classified adverse events into serious, moderate or mild. We reported study results as risk ratios (RR) or mean differences (MD) using 95% confidence intervals (CI) and a random-effects model. We used the GRADE approach to evaluate the overall certainty of the evidence for each outcome.

MAIN RESULTS

Eighteen trials met the inclusion criteria. Trials were conducted in China, South Africa, Kenya and Zambia, Mozambique, Rwanda, Uganda and Zimbabwe. Primary outcomes Serious adverse events: there were no serious adverse events in either treatment arm (11 trials, 3472 participants). Moderate adverse events: there may be a slight increase in moderate adverse events when devices are used compared to standard surgical techniques (RR 1.31, 95% CI 0.55 to 3.10; I²= 68%; 10 trials, 3370 participants; low-certainty evidence); this corresponds to 8 more (ranging from 15 fewer to 84 more) moderate adverse events per 1000 participants. We downgraded the certainty of the evidence for study limitations and imprecision. Secondary outcomes Mild adverse events: we are uncertain about the difference in mild adverse events between groups when devices are used compared to standard surgical techniques (RR 1.09, 95% CI 0.44 to 2.72; I² = 91%; 10 trials, 3370 participants; very low-certainty evidence). We downgraded the certainty of the evidence for study limitations, imprecision and unexplained inconsistency. Operative time: operative time is probably about 17 minutes shorter when using a device rather than standard surgical techniques, which constitutes a clinically meaningful decrease in a procedure (MD -17.26 minutes, 95% CI -19.96 to -14.57; I² = 99%; 14 trials, 4812 participants; moderate-certainty evidence). We downgraded the certainty of the evidence for serious study limitations. The standard surgical technique generally takes about 24 minutes. There may be less postoperative pain during the first 24 hours when circumcision devices are used compared to standard surgical techniques (measured using a visual analog scale [VAS]; MD 1.30 cm lower, 95% CI 2.37 lower to 0.22 lower; I² = 99%; 9 trials, 3022 participants; low-certainty evidence). We downgraded the certainty of the evidence for study limitations and unexplained heterogeneity. There may be little or no difference in postoperative pain experienced during the first seven days when compared with standard surgical techniques (measured using a VAS; MD 0.11 cm higher, 95% CI 0.89 lower to 1.11 higher; I² = 94%; 4 trials, 1430 participants; low-certainty evidence). We downgraded the certainty of the evidence for study limitations and unexplained inconsistency. A higher score on the VAS indicates greater pain. Participants may slightly prefer circumcision devices compared to standard surgical techniques (RR 1.19, 95% CI 1.04 to 1.37; I² = 97%; 15 trials, 4501 participants; low-certainty evidence). We downgraded the certainty of the evidence for study limitations and unexplained inconsistency. We recorded satisfaction as a dichotomous outcome. Higher rates reflected greater satisfaction.

AUTHORS' CONCLUSIONS

We found that there were no serious adverse events reported when using a circumcision device compared to standard surgical techniques, but they may slightly increase moderate adverse effects, and it is unclear whether there is a difference in mild adverse effects. Use of circumcision devices probably reduces the time of the procedure by about 17 minutes, a clinically meaningful time saving. For patients, use of the circumcision device may result in lower pain scores during the first 24 hours and patients may be slightly more satisfied with it compared with standard surgical techniques. Clinicians, patients and policymakers can use these results in conjunction with their own contextual factors to inform the approach that best suits their healthcare settings. High-quality trials evaluating this intervention are needed to provide further certainty regarding the rates of adverse effects and postoperative pain of using devices compared to standard approaches.

No-flip ShangRing circumcision in 10-12 year old boys: Results from randomized clinical trials in Kenya

Background

Attention has recently turned toward the use of device-assisted male circumcision to help scale up male circumcision services in sub-Saharan Africa, with increasing emphasis on younger age groups. We assessed the use of the ShangRing for circumcising the subset of boys aged 10 to 12 years who were enrolled in two randomized clinical trials in Kenya.

Methods

We performed a sub-analysis of outcomes in 197 boys aged 10 to 12 years; a subset who were enrolled in two randomized clinical trials to assess the use of the no-flip ShangRing circumcision technique in men and boys. One trial assessed spontaneous detachment vs. planned removal of the ShangRing 7 days post-circumcision. The second trial compared the use of topical vs. injectable anesthesia with ShangRing circumcision. Aside from baseline characteristics, data was collected and analyzed for each trial separately.

Results

All participants were successfully circumcised. Duration of circumcision, participants requiring a dorsal slit, rate of adverse events, time to complete wound healing, and participant satisfaction were similar between the two groups in each trial. Mean time required for spontaneous ShangRing detachment was 14.82±3.76 days. Topical anesthesia showed a significantly lower mean pain score at the time of application (0.64±1.71 vs. 1.55± 2.21, p = 0.03) as well as postoperatively (0.54±0.88 vs. 1.72±1.56, p<0.0001). Median dwell time of the topical anesthetic was 43 (IQR: 35.5–60) minutes, while the median time it took the injectable anesthetic to take effect was 2.04 (IQR: 1.72–3.09) minutes.

Conclusion

No-flip ShangRing circumcision had a positive safety profile among young adolescent boys, specifically ages 10–12 years. The use of spontaneous device detachment and topical anesthesia with the procedure have shown promising outcomes in this age group. This may have the potential to further increase the acceptability of ShangRing circumcision, and therefore accelerate the scle up of male circumcision services in sub-Saharan Africa.

Simplifying the ShangRing technique for circumcision in boys and men: use of the no-flip technique with randomization to removal at 7 days versus spontaneous detachment

To assess safety of the no-flip ShangRing male circumcision technique and to determine clinical course and safety of spontaneous detachment (i.e., allowing the device to fall off), we conducted a case series of no-flip ShangRing circumcision combined with a randomized controlled trial of removal 7 days postcircumcision versus spontaneous detachment at two health facilities in Kenya. The primary outcome was the safety of the no-flip technique based on moderate and severe adverse events (AEs) during the procedure and through 42-day follow-up. A main secondary outcome was clinical course and safety of spontaneous detachment. Two hundred and thirty males 10 years and older underwent no-flip circumcision; 114 randomized to 7-day removal and 116 to spontaneous detachment. All circumcisions were successfully completed. Overall 5.3% (6/114) of participants in the 7-day group and 1.7% (2/116) in the spontaneous group had an AE; with no differences when compared to the 3% AE rate in historical data from African studies using the original flip technique (P = 0.07 and P = 0.79, respectively). Overall 72.4% (84/116) of participants in the spontaneous group wore the ShangRing until it detached. Among the remaining (27.6%; 32/116), the ring was removed, primarily at the participants' request, due to pain or discomfort. There was no difference in AE rates (P = 0.169), visit day declared healed (P = 0.324), or satisfaction (P = 0.371) between randomization groups. The median time to detachment was 14.0 (IQR: 7–21, range: 5–35) days. The no-flip technique and spontaneous detachment are safe, effective, and acceptable to boys and men 10 years and older. Phimosis and penile adhesions do not limit successful ShangRing circumcision with the no-flip technique.

Clinical Outcomes And Risk Factors In Patients Circumcised By Chinese Shang Ring: A Prospective Study Based On Age And Types Of Penile Disease

Purposes

To explore the efficacy of circumcision with Chinese Shang Ring (CSR) in the different cohorts so that can obtain the best applicable population and manage complications better.

Methods

This study consisted of 657 patients who were circumcised with CSR in our institute between August 2017 and August 2018. All cases were followed up at post-operation for 3 to 15 months. The surgery time (ST), wound healing time (WHT), satisfaction with the appearance of postoperative penis and complications were collected and comparatively analyzed. Multivariate analysis was used to determine the independent risk factors associated with efficacy, which were presented by odd ratios and its 95% confidence index.

Results

All cases wore the CSR successfully. The ST and WHT respectively were 5.75 ± 2.27 mins and 21.15 ± 5.05 days. The long-term complications, total complications (TC), satisfaction and successful circumcision (SC) respectively were 5.30%, 11.70%, 97.70% and 94.70%. For TC and SC, there was a difference between phimosis and redundant foreskin (21.30% vs 6.20%, P<0.001 and 89.20% vs 97.8%, P<0.001, respectively). In terms of satisfaction and SC, adolescents were higher than children (98.70% vs 94.70%, P=0.035 and 96.80% vs 90.10%, P=0.024, respectively) but was similar to adults (98.70% vs 100.00%, P=0.071 and 96.80% vs 98.00%, P=0.257, respectively). The degree of pain and the incidence of wound dehiscence in adults was higher than adolescents (P<0.05). The phimosis (OR= 1.47, 95% CI=1.26–1.79, P<0.001) and childhood (OR= 1.13, 95% CI =1.06–1.36, P<0.001) were associated with poor efficacy.

Conclusion

The curative effect of circumcision by CSR in adolescents was similar to adults, both higher than that of children. However, adults have more severe pain and a higher probability of wound dehiscence in the later stage than adolescents. So, adolescence is probably the best time to be circumcised with CSR.

Rollout of ShangRing circumcision with active surveillance for adverse events and monitoring for uptake in Kenya

INTRODUCTION

Since 2011, Kenya has been evaluating ShangRing device for use in its voluntary medical male circumcision (VMMC) program according to World Health Organization (WHO) guidelines. Compared to conventional surgical circumcision, the ShangRing procedure is shorter, does not require suturing and gives better cosmetic outcomes. After a pilot evaluation of ShangRing in 2011, Kenya conducted an active surveillance for adverse events associated with its use from 2016-2018 to further assess its safety, uptake and to identify any operational bottlenecks to its widespread use based on data from a larger pool of procedures in routine health care settings.

METHODS

From December 2017 to August 2018, HIV-negative VMMC clients aged 13 years or older seeking VMMC at six sites across five counties in Kenya were offered ShangRing under injectable local anesthetic as an alternative to conventional surgical circumcision. Providers described both procedures to clients before letting them make a choice. Outcome measures recorded for clients who chose ShangRing included the proportions who were clinically eligible, had successful device placement, experienced adverse events (AEs), or failed to return for device removal. Clients failing to return for follow up were sought through phone calls, text messages or home visits to ensure removal and complete information on adverse events.

RESULTS

Out of 3,692 eligible clients 1,079 (29.2%) chose ShangRing; of these, 11 (1.0%) were excluded due to ongoing clinical conditions, 17 (1.6%) underwent conventional surgery due to lack of appropriate device size at the time of the procedure, 97.3% (1051/1079) had ShangRing placement. Uptake of ShangRing varied from 11% to 97% across different sites. There was one severe AE, a failed ShangRing placement (0.1%) managed by conventional wound suturing, plus two moderate AEs (0.2%), post removal wound dehiscence and bleeding, that resolved without sequelae. The overall AE rate was 0.3%. All clients returned for device removal from fifth to eleventh day after placement.

CONCLUSION

ShangRing circumcision is effective and safe in the Kenyan context but its uptake varies widely in different settings. It should be rolled out under programmatic implementation for eligible males to take advantage of its unique benefits and the freedom of choice beyond conventional surgical MMC. Public education on its availability and unique advantages is necessary to optimize its uptake and to actualize the benefit of its inclusion in VMMC programs.

Use of topical versus injectable anaesthesia for ShangRing circumcisions in men and boys in Kenya: Results from a randomized controlled trial

BACKGROUND

The ShangRing is a disposable, collar clamp circumcision device pre-qualified for use in men and boys 13 years and above. It has been shown to be faster than conventional circumcision with comparable adverse event (AE) rates and high client satisfaction. Voluntary medical male circumcision (VMMC) has been shown to dramatically reduce the risk of HIV acquisition in males. However, the fear of pain during circumcision is an important barrier to uptake. Use of topical anesthesia thus presents an opportunity to address this.

OBJECTIVES

We sought to evaluate the safety, effectiveness and acceptability of the use of topical anaesthesia with ShangRing circumcision of men and boys 10 years of age and above.

METHODS

Participants were randomised 2:1 to receive topical or injectable anaesthesia. All participants underwent no-flip ShangRing circumcision. The primary outcome measure was pain. Secondary outcomes included ease of use of topical versus injectable anaesthesia, AEs and participant satisfaction.

RESULTS

Compared to the topical group, participants in the injectable group reported significantly more pain on administration of the anesthesia and at approximately 20 minutes after the procedure. In the topical group, sufficient anaesthesia with topical cream was not achieved in 21 (9.3%) cases before the start of the procedure; in another 6 (2.6%), supplementary injectable anaesthesia was required as the circumcision was being carried out. The AE rate was significantly lower (p<0.01) in the topical (0%) vs. the injectable group (4.2%). The most common AE was pain during the post-operative period. All AEs were managed conservatively and resolved without sequeale. 96.7% of participants were satisfied with the appearance of the healed penis and 100% would recommend the ShangRing to others. All seven male circumcision providers involved in the study preferred topical to injectable anaesthesia.

CONCLUSIONS

Our results demonstrate the safety, improved clinical experience, effectiveness, and acceptability of the use of topical anaesthesia in ShangRing circumcision using the no-flip technique. Topical anaesthesia effectively eliminates needlestick pain from the clients' VMMC experience and thus has the potential to increase demand for the service.

Safety and efficacy of the PrePex device in HIV-positive men: A single-arm study in Zimbabwe

Male circumcision (MC) for sexually active, HIV-negative men reduces HIV transmission and averts HIV infections. Excluding HIV-positive men from MC decreases access to additional health and hygiene benefits. In settings where HIV-testing is, or is perceived to be, required for MC, testing may reduce MC uptake. Reducing promotion of HIV testing within MC settings and promoting device-based MC may speed MC scale-up. To assess safety and efficacy of PrePex MC device among HIV-positive men, we conducted a one-arm, open-label, prospective study in otherwise healthy HIV-positive men in Zimbabwe.

Use of the ShangRing circumcision device in boys below 18 years old in Kenya: results from a pilot study

Introduction: Male circumcision is a proven prevention strategy against the spread of HIV. The World Health Organization’s new 2016–2021 strategic framework on voluntary medical male circumcision (VMMC) targets 90% of males aged 10–29 years to receive circumcision by 2021 in 14 priority sub-Saharan countries while anticipating an increase in the demand for infant circumcision. It also states that the use of circumcision devices is a safe and efficient innovation to accelerate attainment of these goals. The primary objective of this pilot study was to evaluate the safety and acceptability of the ShangRing, a novel circumcision device, in boys below 18 years of age.

Methods: A total of 80 boys, 3 months to 17 years old, were circumcised using the no-flip ShangRing technique. All rings were removed 5–7 days later. Participants were evaluated weekly until the wound was completely healed. Data on procedure times, adverse events (AEs), time to clinical wound healing and satisfaction were recorded and analysed.

Results: Nearly all (79/80, 98.8%) circumcisions were successfully completed using the no-flip ShangRing technique without complications. In one (1.2%) case, the outer ring slipped off after the foreskin was removed and the procedure was completed by stitching. The mean circumcision and ring removal times were 7.4 ± 3.2 and 4.4 ± 4.2 min, respectively. There were four (5%) moderate AEs, which were managed conservatively. No severe AEs occurred. The mean time to complete clinical healing was 29.8 ± 7.3 days. Participants or their parents liked ShangRing circumcision because it improved hygiene, was quick and possessed an excellent cosmetic appearance. Most (72/80, 94.7%) were very satisfied with the appearance of the circumcised penis, and all (100%) said they would recommend circumcision to others.

Conclusions: Our results suggest that no-flip ShangRing VMMC is safe and acceptable in boys below 18 years of age. Our results are to be compared those seen following ShangRing VMMC in African men. Further study with larger sample sizes are needed to explore the scalability of the ShangRing in larger paediatric cohorts in Africa. We believe that the ShangRing has great potential for use in all age groups from neonates to adults, which would simplify device implementation.

Safety and Acceptability of the PrePex Device When Used in Routine Male Circumcision Service Delivery During Active Surveillance in Zimbabwe

Background:

Male circumcision devices have the potential to accelerate voluntary medical male circumcision roll-out, with PrePex being one promising device. Here, we present findings on safety and acceptability from active surveillance of the implementation of PrePex among 1000 males circumcised in Zimbabwe.

Methods:

The first 1000 men consecutively circumcised using PrePex during routine service delivery were actively followed up. Outcome measures included PrePex uptake, attendance for postcircumcision visits, and adverse events (AEs). A survey was conducted among 500 consecutive active surveillance clients to assess acceptability and satisfaction with PrePex.

Results:

A total of 2156 men aged 18 years or older were circumcised across the 6 PrePex active surveillance sites. Of these, 1000 (46.4%) were circumcised using PrePex. Among them, 4 (0.4%) self-removals that required surgery (severe AEs) were observed. Six (0.6%) removals by providers (moderate AEs) did not require surgery. A further 280 (28%) AEs were mild or moderate pain during device removal. There were also 12 (1.2%) moderate AEs unrelated to pain. All AEs resolved without sequelae. There was high adherence to follow-up appointments, with 97.7% of clients attending the scheduled day 7 visit. Acceptability of PrePex was high among survey participants, 93% indicated willingness to recommend the device to peers. Of note, 95.8% of respondents reported experiencing pain when the device was being removed. Additionally, 85.2% reported experiencing odor while wearing the device or during removal.

Conclusions:

Active surveillance of the first 1000 men circumcised using PrePex suggests that the device is both safe and acceptable when used in routine service delivery.

Factors Associated With Delayed Healing in a Study of the PrePex Device for Adult Male Circumcision in Kenya

OBJECTIVES

To explore factors associated with healing requiring more than 6 weeks after placement of the PrePex device for adult medical male circumcision.

METHODS

We enrolled 427 men ages 18-49 years in an observational study of PrePex at 1 urban and 2 peripheral clinics in western Kenya. Participants were scheduled for device removal at day 7 and a follow-up visit at day 42 (allowable range, 40-44) at which the provider recorded wound status, with complete healing defined as a dry wound without any scab, later confirmed by site investigator review of digital penile photographs. We performed univariate and multivariate logistic regression to explore associations between selected demographic, surgical, and follow-up factors and delayed healing (not healed by day 42 visit).

RESULTS

Of the 427 men, 341 completing a day 42 visit with physical examination and recorded healing status were included. Fifty-four percent of included men were healed by day 42 visit. Factors associated with delayed healing in univariate analysis and remaining significant in the multivariate analysis were as follows: age 25 years or older [odds ratio (OR): 1.8; 95% confidence interval (CI): 1.4 to 2.4], an adverse event by day 44 (OR: 1.4; 95% CI: 1.03 to 2.0), and severe pain during device removal (protective association: OR: 0.7; 95% CI: 0.5 to 0.99).

CONCLUSIONS

Older age (25+ years), occurrence of an adverse event, and lesser self-reported pain at device removal were associated with delayed wound healing. If confirmed by larger surveillance studies, these results should be incorporated into the counseling given to male circumcision clients.

Men's Understanding of and Experiences During the Postcircumcision Abstinence Period: Results From a Field Study of ShangRing Circumcision During Routine Clinical Services in Kenya and Zambia

Background:

Men's understanding of counseling messages after voluntary medical male circumcision (VMMC) plays an important role in whether they follow them. Data on triggers for early resumption of sex may be useful as scale-up of VMMC for HIV prevention continues in sub-Saharan Africa.

Methods:

Data on understanding of post-VMMC abstinence recommendations, resumption of sex, condom use, and triggers for resuming sex were collected from participants during a follow-up interview 35–42 days after ShangRing circumcision in Kenya and Zambia.

Results:

Of 1149 men who had ShangRing circumcision, 1096 (95.4%) completed follow-up. Nearly all (99.2%) reported being counseled to abstain from sex post-VMMC; among those, most (92.2%) recalled the recommended abstinence period was 6 weeks. Most men (94.1%) reported that the counselor gave reasons for post-VMMC abstinence and recalled appropriate reasons. Few (13.4%) men reported resuming sex at 35–42 days' follow-up. Among those, 54.8% reported never using a condom post-VMMC. Younger participants (odds ratio 0.3, 95% confidence interval: 0.2 to 0.5, P < 0.0001) and those reporting at least some condom use at baseline (odds ratio 0.5, 95% confidence interval: 0.3 to 0.7, P = 0.0003) were less likely to report resuming sex. Among men who reported some condom use, most (71.5%) said condoms were much easier or easier to use after circumcision. Men reported various reasons for early resumption of sex, primarily strong sexual desire (76.4%).

Conclusions:

Most men reported awareness of and adherence to the counseling recommendations for post-VMMC abstinence. A minority reported early resumption of sex, and, among those, condom use was low. Results could be used to improve post-VMMC counseling.

Randomized Controlled Trial of the ShangRing for Adult Medical Male Circumcision: Safety, Effectiveness, and Acceptability of Using 7 Versus 14 Device Sizes

Objectives:

To assess the safety, effectiveness, and acceptability of providing a reduced number of ShangRing sizes for adult voluntary medical male circumcision (VMMC) within routine service delivery in Lusaka, Zambia.

Methods:

We conducted a randomized controlled trial and enrolled 500 HIV-negative men aged 18–49 years at 3 clinics. Participants were randomized to 1 of 2 study arms (Standard Sizing arm vs Modified Sizing arm) in a 1:1 ratio. All 14 adult ShangRing sizes (40–26 mm inner diameter, each varying by 1 mm) were available in the Standard Sizing arm; the Modified Sizing arm used every other size (40, 38, 36, 34, 32, 30, 28 mm inner diameter). Each participant was scheduled for 2 follow-up visits: the removal visit (day 7 after placement) and the healing check visit (day 42 after placement), when they were evaluated for adverse events (AEs), pain, and healing.

Results:

Four hundred and ninety-six men comprised the analysis population, with 255 in the Standard Sizing arm and 241 in the Modified Sizing arm. Three men experienced a moderate or severe AEs (0.6%), including 2 in the Standard Sizing arm (0.8%) and 1 in the Modified Sizing arm (0.4%). 73.2% of participants were completely healed at the scheduled day 42 healing check visit, with similar percentages across study arms. Virtually all (99.6%) men, regardless of study arm, stated that they were very satisfied or satisfied with the appearance of their circumcised penis, and 98.6% stated that they would recommend ShangRing circumcision to family/friends.

Conclusions:

The moderate/severe AE rate was low and similar in the 2 study arms, suggesting that provision of one-half the number of adult device sizes is sufficient for safe service delivery. Effectiveness, time to healing, and acceptability were similar in the study arms. The simplicity of the ShangRing technique, and its relative speed, could facilitate VMMC program goals. In addition, sufficiency of fewer device sizes would simplify logistics and inventory.

Surgical Outcomes of Newly Trained ShangRing Circumcision Providers

BACKGROUND

Devices can potentially accelerate scale-up of voluntary medical male circumcision in sub-Saharan Africa. Studies have demonstrated advantages of the ShangRing device over conventional circumcision. With the need to train providers rapidly for scale-up, concerns arise about the transferability of techniques and the expertise of new trainees.

METHODS

We compared outcomes of ShangRing circumcisions conducted in Kenya by experienced providers (experience with more than 100 ShangRing circumcisions) and newly trained providers (trained in Kenya by the experienced providers before the study began). During training, trainees performed at least 7 ShangRing circumcisions and 3 removals. Newly trained providers received intermittent clinical mentoring initially during the study but otherwise conducted circumcisions on their own.

RESULTS

Four hundred six and 115 ShangRing procedures were performed by the new trainees and the experienced providers, respectively. The mean duration of circumcisions was 6.2 minutes for both trained and experienced provider groups (P = 0.45), whereas the mean pain score (on an 11-point scale) was 2.5 and 3.2, respectively (P = 0.65). There was no difference in the proportion of participants healed by the day 42 visit (P = 0.13) nor in the incidence of moderate and severe adverse events observed (P = 0.16). Participants in both groups were equally satisfied with final wound cosmesis.

DISCUSSION

Results demonstrate that the ShangRing circumcision technique is easy to learn and master. Newly trained providers can safely conduct ShangRing circumcisions in routine service settings. The ShangRing can facilitate rapid rollout of voluntary medical male circumcision for HIV prevention in sub-Saharan Africa.

Comparative efficacy and safety of different circumcisions for patients with redundant prepuce or phimosis: A network meta-analysis

BACKGROUND

Phimosis and redundant prepuce are defined as the inability of the foreskin to be retracted behind the glans penis in uncircumcised males. To synthesize the evidence and provide the hierarchies of different circumcisions for phimosis and redundant prepuce, we performed an overall network meta-analysis (NMA) based on their comparative efficacy and safety.

MATERIAL AND METHODS

Electronic databases including PubMed, Embase, Wan Fang, VIP, CNKI and CBM database were researched from randomized controlled trials (RCTs) for redundant prepuce or phimosis. We conducted the direct and indirect comparisons by aggregate data drug information system (ADDIS) software. Moreover, consistency models were applied to assess the differences among the male circumcision practices, and the ranks based on probabilities of intervention for the different endpoints were performed. Node-splitting analysis was used to test inconsistency.

RESULTS

Eighteen RCTs were included with 6179 participants. Compared with the conventional circumcision(CC), two new styles of circumcisions, the disposable circumcision suture device(DCSD) and Shang Ring circumcision(SRC), provided significantly shorter operation time[DCSD: standardized mean difference (SMD) = -20.60, 95% credible interval(CI) (-23.38, -17.82); SRC: SMD = -19.16, 95%CI (-21.86, -16.52)], shorter wound healing time [DCSD:SMD = -4.19, 95%CI (-8.24,-0.04); SRC: SMD = 4.55, 95%CI (1.62, 7.57); ] and better postoperative penile appearance [DCSD: odds ratios odds ratios (OR) = 11.42, 95%CI (3.60, 37.68); SRC: OR = 3.85,95%CI (1.29, 12.79)]. Additionally, DCSD showed a lower adverse events rate than other two treatments. However, no significant difference was shown in all surgeries for 24 h postoperative pain score. Node-splitting analysis showed that no significant inconsistency was existed (P > 0.05).

CONCLUSIONS

Based on the results of NMA, DCSD may be a most effective and safest choice for phimosis and redundant prepuce. DCSD has the advantages of a shorter operation time, better postoperative penile appearance, fewer complication and shorter wound healing time. However, with the limitations of our study, additional multi-center RCTs are needed to evaluate the outcomes.

Gender-Specific Combination HIV Prevention for Youth in High-Burden Settings: The MP3 Youth Observational Pilot Study Protocol

Background

Nearly three decades into the epidemic, sub-Saharan Africa (SSA) remains the region most heavily affected by human immunodeficiency virus (HIV), with nearly 70% of the 34 million people living with HIV globally residing in the region. In SSA, female and male youth (15 to 24 years) are at a disproportionately high risk of HIV infection compared to adults. As such, there is a need to target HIV prevention strategies to youth and to tailor them to a gender-specific context. This protocol describes the process for the multi-staged approach in the design of the MP3 Youth pilot study, a gender-specific, combination, HIV prevention intervention for youth in Kenya.

Objective

The objective of this multi-method protocol is to outline a rigorous and replicable methodology for a gender-specific combination HIV prevention pilot study for youth in high-burden settings, illustrating the triangulated methods undertaken to ensure that age, sex, and context are integral in the design of the intervention.

Methods

The mixed-methods, cross-sectional, longitudinal cohort pilot study protocol was developed by first conducting a systematic review of the literature, which shaped focus group discussions around prevention package and delivery options, and that also informed age- and sex- stratified mathematical modeling. The review, qualitative data, and mathematical modeling created a triangulated evidence base of interventions to be included in the pilot study protocol. To design the pilot study protocol, we convened an expert panel to select HIV prevention interventions effective for youth in SSA, which will be offered in a mobile health setting. The goal of the pilot study implementation and evaluation is to apply lessons learned to more effective HIV prevention evidence and programming.

Results

The combination HIV prevention package in this protocol includes (1) offering HIV testing and counseling for all youth; (2) voluntary medical circumcision and condoms for males; (3) pre-exposure prophylaxis (PrEP), conditional cash transfer (CCT), and contraceptives for females; and (4) referrals for HIV care among those identified as HIV-positive. The combination package platform selected is mobile health teams in an integrated services delivery model. A cross-sectional analysis will be conducted to determine the uptake of the interventions. To determine long-term impact, the protocol outlines enrolling selected participants in mutually exclusive longitudinal cohorts (HIV-positive, PrEP, CCT, and HIV-negative) followed by using mobile phone text messages (short message service, SMS) and in-person surveys to prospectively assess prevention method uptake, adherence, and risk compensation behaviors. Cross-sectional and sub-cohort analyses will be conducted to determine intervention packages uptake.

Conclusions

The literature review, focus groups, and modeling indicate that offering age- and gender- specific combination HIV prevention interventions that include biomedical, behavioral, and structural interventions can have an impact on HIV risk reduction. Implementing this protocol will show the feasibility of delivering these services at scale. The MP3 Youth study is one of the few combination HIV prevention intervention protocols incorporating youth- and gender-specific interventions in one delivery setting. Lessons learned from the design of the protocol can be incorporated into the national guidance for combination HIV prevention for youth in Kenya and other high-burden SSA settings.

Novel penile circumcision suturing devices versus the shang ring for adult male circumcision: a prospective study

INTRODUCTION

To evaluate the safety and efficacy of a novel penile circumcision suturing devices PCSD and Shang ring (SR) for circumcision in an adult population.

MATERIALS AND METHODS

A total of 124 outpatients were randomly assigned to receive PCSD (n=62) or SR (n=62). Patient characteristics, operative time, blood loss, return to normal activities time (RNAT), visual analogue scale (VAS), scar width, wound healing time, cosmetic result, and complications were recorded.

RESULTS

There were no significant differences in blood loss, RNAT, or complications between the two groups. There were no significant differences in the VAS scores at theduring operation, and 6 or 24 hours after surgery (P>0.05). The wound scar width was wider in the SR group than in the PCSD group (P<0.01). Patients in the SR group had significantly longer wound healing time compared with those in the PCSD group (P<0.01). Patients who underwent PCSD wereere significantly more satisfied with the cosmetic results (P<0.01).

CONCLUSIONS

SR and PCSD are safe and effective minimally invasive techniques for adult male circumcision. Compared with SRs, PCSDs have the advantages of faster postoperative incision healing and a good effect on wound cosmetics.

Easy, Faster, and Not Bloody: Providers' Perceptions on PrePex™ in South Africa

PrePex™ (Circ MedTech Ltd., Tortola, British Virgin Islands) devices are being evaluated in several countries for scale-up of medical male circumcision (MMC) as an HIV prevention intervention. Health care workers' perceptions should be considered prior to scale-up. A cross-sectional open-ended questionnaire was administered to health care workers from nine MMC programs in South Africa that provided either PrePex™ and surgical circumcision (mixed sites) or surgical circumcision only (surgery-only sites). A total of 77 health care workers (37 at mixed sites and 40 at surgery-only sites) with median ages of 29 years (interquartile range 27-37) and 34 years (interquartile range 29-42), respectively, were recruited into the study. The perceived benefits of PrePex™ MMC for health care workers were: device simplicity, convenience, bloodless, and ease of use. Identified challenges included limited public knowledge of device, pain, smell of necrotic skin, and delayed healing. Health care providers perceived the PrePex™ MMC device to be simple and adaptable for existing MMC programs.

Safety and Efficacy of the PrePex Male Circumcision Device: Results From Pilot Implementation Studies in Mozambique, South Africa, and Zambia

BACKGROUND

Fourteen countries in East and Southern Africa have engaged in national programs to accelerate the provision of voluntary medical male circumcision (VMMC) since 2007. Devices have the potential to accelerate VMMC programs by making the procedure easier, quicker, more efficient, and widely accessible.

METHODS

Pilot Implementation studies were conducted in Mozambique, South Africa, and Zambia. The primary objective of the studies was to assess the safety of PrePex device procedures when conducted by nurses and clinical officers in adults and adolescent males (13-17 years, South Africa only) with the following end points: number and grade of adverse events (AEs); pain-related AEs measured using visual analog score; device displacements/self-removals; time to complete wound healing; and procedure times for device placement and removal.

RESULTS

A total of 1401 participants (1318 adult and 83 adolescent males) were circumcised using the PrePex device across the 3 studies. Rates of moderate/severe AEs were low (1.0%; 2.0%; and 2.8%) in the studies in Mozambique, Zambia, and South Africa, respectively. Eight early self-removals of 1401 (0.6%) were observed, all required corrective surgery. High rates of moderate/severe pain-related AEs were recorded especially at device removal in South Africa (34.9%) and Mozambique (59.5%). Ninety percent of participants were healed at day 56 postplacement.

DISCUSSION

The study results from the 3 countries suggest that the implementation of the PrePex device using nonphysician health care workers is both safe and feasible, but better pain control at device removal needs to be put in place to increase the comfort of VMMC clients using the PrePex device.

Innovative Methods of Male Circumcision for HIV Prevention-Getting the Right Evidence

World Health Organization recommends that countries with hyperendemic and generalized HIV epidemics implement voluntary medical male circumcision programs for HIV prevention. Innovative methods of male circumcision including devices have the potential to simplify the procedure, reduce time and cost, increase client acceptability, enhance safety, and expand the numbers of providers who may perform circumcision. We describe work led by World Health Organization and supported by global partners to define a pathway for the evaluation of efficacy and safety of male circumcision devices, to set priority criteria, and to establish a process to guide the use of devices in publicly funded voluntary medical male circumcision programs for HIV prevention. A device classification scheme, an expert Technical Advisory Group on Innovations in Male Circumcision, and a formal prequalification program have also guided considerations on safe use of devices. A rigorous approach was deemed appropriate given the intervention is for use among healthy men for public health purposes. The pathway and processes led to coordinated research, better standardization in research outcomes, and guidance that informed the research, introduction and implementation phases. The lessons learnt from this case study can inform evaluation and use of future public health innovations.

The characteristics of circular disposable devices and in situ devices for optimizing male circumcision: a network meta-analysis

In situ device (ISD) and circular disposable device (CDD) are used for optimizing male circumcision (MC), but evidence to explore the characteristics of these two devices is insufficient. In order to explore this issue systematically and provide reliable evidence, ten published randomized controlled trials (RCTs) exploring the safety and efficacy of ISDs and CDDs were included (involving 4649 men). Moderate quality of the RCTs included was found after assessment. Pairwise meta-analyses and network meta-analyses were processed in stata 13.0 and AIDDS v1.16.6 respectively. According to the outcomes that were statistically significant in both pairwise and network meta-analyses, ISD was found to have less intraoperative blood loss (IB), less operative time (OT) and less incidence of wound bleeding (WB) than conventional circumcision (CC); ISD was found to have less WB but more wound healing time (WHT) than CDD; CDD was found to have less IB and less OT than CC. CDD tended to have the best wound healing condition and least pain experience; ISD tended to have the least IB, least OT, least WB, and highest satisfaction rate. With their own superiorities in many aspects, CDD and ISD are both safe and effective devices for optimizing MC.

Estimation of country-specific and global prevalence of male circumcision

BACKGROUND

Male circumcision (MC) status and genital infection risk are interlinked and MC is now part of HIV prevention programs worldwide. Current MC prevalence is not known for all countries globally. Our aim was to provide estimates for country-specific and global MC prevalence.

METHODS

MC prevalence data were obtained by searches in PubMed, Demographic and Health Surveys, AIDS Indicator Surveys, and Behavioural Surveillance Surveys. Male age was ≥15 years in most surveys. Where no data were available, the population proportion whose religious faith or culture requires MC was used. The total number of circumcised males in each country and territory was calculated using figures for total males from (i) 2015 US Central Intelligence Agency (CIA) data for sex ratio and total population in all 237 countries and territories globally and (ii) 2015 United Nations (UN) figures for males aged 15-64 years.

RESULTS

The estimated percentage of circumcised males in each country and territory varies considerably. Based on (i) and (ii) above, global MC prevalence was 38.7 % (95 % confidence interval [CI]: 33.4, 43.9) and 36.7 % (95 % CI: 31.4, 42.0). Approximately half of circumcisions were for religious and cultural reasons. For countries lacking data we assumed 99.9 % of Muslims and Jews were circumcised. If actual prevalence in religious groups was lower, then MC prevalence in those countries would be lower. On the other hand, we assumed a minimum prevalence of 0.1 % related to MC for medical reasons. This may be too low, thereby underestimating MC prevalence in some countries.

CONCLUSIONS

The present study provides the most accurate estimate to date of MC prevalence in each country and territory in the world. We estimate that 37-39 % of men globally are circumcised. Considering the health benefits of MC, these data may help guide efforts aimed at the use of voluntary, safe medical MC in disease prevention programs in various countries.

Clinical trials using the Shang Ring device for male circumcision in Africa: a review

Male circumcision (MC) reduces the risk of HIV and other sexually transmitted infections (STIs), including human papillomavirus (HPV) and herpes simplex virus type 2 (HSV-2), and is recommended as an important component of a comprehensive package of HIV prevention interventions. While computer modeling has demonstrated that substantial reductions in HIV could be achieved with rapid scale-up of MC services in sub-Saharan Africa, scale-up has lagged due to scarcity of trained providers coupled with relative technical difficulty of recommended surgical MC techniques. Simplified techniques, such as devices, have the potential to allow for a more rapid roll-out of MC. One such device is the Shang Ring, a novel disposable MC device that eliminates the need for suturing and has been on the Chinese market since 2005. Results from Chinese studies have demonstrated that the Shang Ring is both safe and easy to use. Since 2008, a series of studies using the Shang Ring for adult MC have been carried out in Kenya, Uganda and Zambia, according to guidelines established by World Health Organization (WHO) for clinical evaluation of new devices for adult MC. These include a proof of concept study, a study of delayed removal of the Shang Ring, two studies comparing Shang Ring circumcision to conventional surgical approaches, and a large field trial to evaluate safety of Shang Ring circumcision during routine service delivery. Results from these studies demonstrate that the Shang Ring has an excellent safety profile and that Shang Ring circumcision is relatively easy to teach and learn, making Shang Ring MC an appealing technique for use in sub-Saharan Africa where doctors are in short supply and non-physician providers such as nurses and clinical officers are playing a major role in providing MC through task shifting. Shang Ring MC and device removals were uneventfully performed by trained nurses and clinical officers, who preferred the Shang Ring to conventional surgical techniques. Adverse event rates were similar to those observed with conventional surgical circumcision and were managed with, at most, minor interventions, resolving with no long-term sequale. Perhaps one of the biggest advantages of the Shang Ring is the relatively short 3-6 minutes procedure time. Importantly, men also preferred the Shang Ring compared to conventional circumcision and satisfaction with cosmetic appearance of their circumcised penis was very high. The vast majority of participants in studies in Africa as well as China have reported few problems and little disruption to daily life while wearing the device. The Shang Ring holds great promise as an innovative technology that has the potential to facilitate the safe and effective scale-up of circumcision services in settings where MC is not widely used and where the burden of HIV-disease is high.

Piloting PrePex for Adult and Adolescent Male Circumcision in South Africa--Pain Is an Issue

BACKGROUND

The World Health Organisation and the Joint United Nations Programme on HIV/AIDS have recommended the scale-up of Medical Male Circumcision (MMC) in countries with high HIV and low MMC prevalence. PrePex device circumcision is proposed as an alternate method for scaling up MMC.

OBJECTIVE

Evaluate safety and feasibility of PrePex in South Africa.

DESIGN

A multisite prospective cohort PrePex study in adults and adolescents at three MMC clinics. Participants were followed-up 8 times, up to 56 days after PrePex placement.

RESULTS

In total, 398 PrePex circumcisions were performed (315 adults and 83 adolescents) their median ages were 26 (IQR: 22-30) and 16 years (IQR: 15-17), respectively. The median time for device placement across both groups was 6 minutes (IQR: 5-9) with the leading PrePex sizes being B (30%) and C (35%) for adults (18-45 years), and A (31%) and B (38%) for adolescents (14-17 years). Additional sizes (size 12-20) were rarely used, even in the younger age group. Pain of device application was minimal but that of removal was severe. However, described pain abated rapidly and almost no pain was reported 1 hour after removal. The Adverse Events rate were experienced by 2.7% (11/398) of all participants, three of which were serious (2 displacements and 1 self-removal requiring prompt surgery). None of the Adverse Events required hospitalization. The majority of participants returned to work within a day of device placement.

CONCLUSION

Our study shows that PrePex is a safe MMC method, for males 14 years and above. PrePex circumcision had a similar adverse event rate to that reported for surgical MMC, but device removal caused high levels of pain, which subsided rapidly.

Adult male circumcision with a circular stapler versus conventional circumcision: A prospective randomized clinical trial

Male circumcision is the most frequently performed procedure by urologists. Safety and efficacy of the circumcision procedure requires continual improvement. In the present study, we investigated the safety and efficacy of a new male circumcision technique involving the use of a circular stapler. In total, 879 consecutive adult male patients were randomly divided into 2 groups: 441 underwent stapler circumcision, and 438 underwent conventional circumcision. The operative time, pain score, blood loss volume, healing time, treatment costs, and postoperative complications were compared between the two groups. The operative time and blood loss volume were significantly lower in the stapler group than in the conventional group (6.8 ± 3.1 vs 24.2 ± 3.2 min and 1.8 ± 1.8 vs 9.4 ± 1.5 mL, respectively; P<0.01 for both). The intraoperative and postoperative pain scores were significantly lower in the stapler group than in the conventional group (0.8 ± 0.5 vs 2.4 ± 0.8 and 4.0 ±0.9 vs 5.8 ± 1.0, respectively; P<0.01 for both). Additionally, the stapler group had significantly fewer complications than the conventional group (2.7% vs 7.8%, respectively; P<0.01). However, the treatment costs in the stapler group were much higher than those in the conventional group (US$356.60 ± 8.20 vs US$126.50 ± 7.00, respectively; P<0.01). Most patients (388/441, 88.0%) who underwent stapler circumcision required removal of residual staple nails. Overall, the present study has shown that stapler circumcision is a time-efficient and safe male circumcision technique, although it requires further improvement.

A systematic review and meta-analysis of circumcision with Shang Ring vs conventional circumcision

Herein, we conduct a systematic review and meta-analysis of the current evidence to compare the safety and efficacy of Shang Ring circumcision (SRC) with conventional circumcision (CC) for male patients. Articles were searched by 2 independent reviewers. Overall, 8 randomized controlled trials involving 3314 patients were included. Compared with the CC group, SRC is associated with shorter operative time, lower intraoperative pain score, higher satisfaction with penile appearances, less intraoperative blood loss, lower adverse event rate, and lower wound bleeding rate. SRC appears to be a safer and more effective choice in comparison with CC for male patients.

Field study of adult male circumcision using the ShangRing in routine clinical settings in Kenya and Zambia

BACKGROUND

Circumcision devices can facilitate adult voluntary medical male circumcision programs for HIV prevention. The World Health Organization recommends field studies to confirm the safety of devices in local settings.

METHODS

We evaluated the safety of the ShangRing device in routine service delivery by measuring adverse event (AE) rates overall and by HIV status. We enrolled men aged 18-54 years and scheduled them for 2 post-circumcision follow-up visits at day 7 for device removal and days 35-42. Men were examined to document AEs and healing and to ascertain client acceptability. Provider preferences were also assessed.

RESULTS

We enrolled 1163 men (557 in Kenya and 606 in Zambia); the as-treated analysis population comprised 1149 men, including 84 HIV-positive men. There were no serious AEs and 2 severe AEs: 1 severe wound dehiscence and 1 severe pain, both of which resolved with treatment. There were 18 moderate/severe AEs among 16 men (1.4% of men; 95% confidence interval: 0.8% to 2.3%). The most common AE was wound dehiscence (9 men, 0.8%). Healing was similar between HIV-infected and uninfected men, with 85.7% and 87.3% completely healed at days 35-42. Most men (94.8%) were very satisfied with post-circumcision appearance of the penis, and almost all would recommend a ShangRing procedure. Nineteen of 21 providers preferred the ShangRing over conventional surgery.

CONCLUSIONS

The ShangRing has an excellent safety profile with few hemorrhagic and infectious complications. The ShangRing is well accepted by clients and preferred by providers, making it a potential boon to the scale-up of adult voluntary medical male circumcision in African countries.

Scaling-up voluntary medical male circumcision - what have we learned?

In 2007, the World Health Organization (WHO) and the joint United Nations agency program on HIV/AIDS (UNAIDS) recommended voluntary medical male circumcision (VMMC) as an add-on strategy for HIV prevention. Fourteen priority countries were tasked with scaling-up VMMC services to 80% of HIV-negative men aged 15–49 years by 2016, representing a combined target of 20 million circumcisions. By December 2012, approximately 3 million procedures had been conducted. Within the following year, there was marked improvement in the pace of the scale-up. During 2013, the total number of circumcisions performed nearly doubled, with approximately 6 million total circumcisions conducted by the end of the year, reaching 30% of the initial target. The purpose of this review article was to apply a systems thinking approach, using the WHO health systems building blocks as a framework to examine the factors influencing the scale-up of the VMMC programs from 2008–2013. Facilitators that accelerated the VMMC program scale-up included: country ownership; sustained political will; service delivery efficiencies, such as task shifting and task sharing; use of outreach and mobile services; disposable, prepackaged VMMC kits; external funding; and a standardized set of indicators for VMMC. A low demand for the procedure has been a major barrier to achieving circumcision targets, while weak supply chain management systems and the lack of adequate financial resources with a heavy reliance on donor support have also adversely affected scale-up. Health systems strengthening initiatives and innovations have progressively improved VMMC service delivery, but an understanding of the contextual barriers and the facilitators of demand for the procedure is critical in reaching targets. There is a need for countries implementing VMMC programs to share their experiences more frequently to identify and to enhance best practices by other programs.

Safety, effectiveness and acceptability of the PrePex device for adult male circumcision in Kenya

Objective

To assess the safety, effectiveness and acceptability of the PrePex device for adult medical male circumcision (MMC) in routine service delivery in Kenya.

Methods

We enrolled 427 men ages 18–49 at one fixed and two outreach clinics. Procedures were performed by trained clinical officers and nurses. The first 50 enrollees were scheduled for six follow-up visits, and remaining men were followed at Days 7 and 42. We recorded adverse events (AEs) and time to complete healing, and interviewed men about acceptability and pain.

Results

Placement and removal procedures each averaged between 3 and 4 minutes. Self-reported pain was minimal during placement but was fleetingly intense during removal. The rate of moderate/severe AEs was 5.9% overall (95% confidence interval [CI] 3.8%–8.5%), all of which resolved without sequelae. AEs included 5 device displacements, 2 spontaneous foreskin detachments, and 9 cases of insufficient foreskin removal. Surgical completion of MMC was required for 9 men (2.1%). Among the closely monitored first 50 participants, the probability of complete healing by Day 42 was 0.44 (95% CI 0.30–0.58), and 0.90 by Day 56. A large majority of men was favorable about their MMC procedure and would recommend PrePex to friends and family.

Conclusions

The PrePex device was effective for MMC in Kenya, and well-accepted. The AE rate was higher than reported for surgical procedures there, or in previous PrePex studies. Healing time is longer than following surgical circumcision. Provider experience and clearer counseling on post-placement and post-removal care should lead to lower AE rates.
