Evaluation of clinical curative effects of disposable stitching instrument in redundant prepuce patients

Device-assisted versus manual circumcision: a prospective, comparative, multicenter study

BACKGROUND

Circumcision is a common urological procedure performed for various medical, cultural, religious, and aesthetic reasons.

AIM

This study aimed to compare the effectiveness and safety of device-assisted (DeCi) and manual circumcision (MaCi) in adult European patients.

METHODS

We conducted a prospective, comparative, non-randomized multicenter study including 200 consecutive adult males undergoing circumcision under local anesthesia. Patients were divided into two groups (MaCi or DeCi) based on patient preferences following proper counseling. Follow-up was scheduled at 1 week and 1 month post-surgery. Surgical and postoperative outcomes were recorded, with patient satisfaction with aesthetic results as the primary outcome, and procedure-related complications as secondary outcomes. Satisfaction was assessed using a 5-point Likert scale, while postoperative complications were classified using the Clavien-Dindo (CD) system.

OUTCOMES

A total of 200 patients (100 per group) were included. The DeCi group had a significantly shorter mean operative time than the MaCi group (11.20 ± 5.92 vs. 23.20 ± 7.93 minutes, P < .001). Patient satisfaction with aesthetic results was significantly higher in the DeCi group, with 67.4% of patients being "very satisfied" or "satisfied" compared to 36.7% in the MaCi group (P < .001). The DeCi group also reported significantly lower perceived pain during surgery (mean ± SD visual analogue scale [VAS] score: 1.54 ± 1.77 vs. 4.20 ± 2.10 points, P = .025) and at 1 month postoperatively (mean ± SD VAS score: 0.54 ± 1.03 vs. 2.35 ± 2.77, P < .001). Intraoperative and postoperative complication rates were similar between groups, with no significant differences (P > .05). Only 5% of patients in the MaCi group and 4% in the DeCi group experienced a CD Grade ≥ 3 postoperative complication.

CLINICAL IMPLICATIONS

DeCi appears to offer superior aesthetic outcomes and reduced pain compared to MaCi, making it a promising option for circumcision in adult European men.

STRENGTHS & LIMITATIONS

This is the first study directly comparing DeCi and MaCi in a European adult population. The study's strengths include its prospective multicenter design, large sample size, and use of validated tools for outcome evaluation, which enhance the reliability and generalizability of the results. However, the non-randomized design, the age difference between groups, the testing of only one circumcision device model, and the lack of a cost-effectiveness analysis limit the generalizability of the findings.

CONCLUSION

In adult European men, DeCi offers superior aesthetic results and a similar safety profile compared to MaCi, though further research is needed to address the study's limitations.

Optimizing treatment strategies for pediatric phimosis and redundant prepuce: a comparative study of traditional circumcision and disposable circumcision stapler

Objective

To investigate the surgical outcomes and complication rates of traditional circumcision and disposable circumcision stapler in the treatment of pediatric patients with phimosis and redundant prepuce.

Methods

A retrospective analysis was conducted on pediatric patients with phimosis or preputial redundancy treated at our pediatric surgery department from January 2022 to December 2023. The patients were divided into two groups: treated with traditional circumcision (control group) and treated with a disposable circumcision stapler (experimental group). Surgical parameters (operation time, intraoperative bleeding), postoperative outcomes (postoperative pain scores, wound healing time, severe edge swelling, wound dehiscence, postoperative rebleeding, postoperative infection, aesthetic satisfaction), were compared between the two groups.

Results

A total of 301 pediatric patients were included in our study, with 146 in the traditional group and 155 in the stapler group. The stapler group showed significantly lower values in operation time, intraoperative bleeding, and postoperative rebleeding compared to the traditional group (P < 0.05). However, the traditional group had a significant advantage in postoperative wound healing time and the occurrence of severe edge swelling (P < 0.05). There were no significant differences between the two groups in terms of anesthetic drug dosage, postoperative pain level, postoperative infection rate, wound dehiscence, and aesthetic satisfaction (P > 0.05).

Conclusion

In the treatment of pediatric phimosis and redundant prepuce, the advantage of traditional circumcision lies in faster postoperative recovery and less severe edge swelling. The disposable circumcision stapler excels in thorough hemostasis, easy and safe operation, suitable for primary medical use, but lags behind in postoperative recovery compared to the traditional method. Each treatment approach has its own advantages, and the choice should be based on the actual condition and circumstances of the patient. Personalized treatment decisions should be made collaboratively to achieve the best therapeutic outcomes.

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.

Upregulation of microRNA miR-141-3p and its prospective targets in endometrial carcinoma: a comprehensive study

The clinicopathological value of microRNA-141-3p (miR-141-3p) and its prospective target genes in endometrial carcinoma (EC) remains unclear. The present study determined the expression level of miR-141-3p in EC via quantitative real-time PCR (RT-qPCR). RT-qPCR showed a markedly higher expression level of miR-141-3p in EC tissues than in non-EC endometrium tissues (P < 0.0001). The microarray and miRNA-seq data revealed upregulation of miR-141-3p. Integrated analysis based on 675 cases of EC and 63 controls gave a standardized mean difference of 1.737, confirmed the upregulation of miR-141-3p. The Kaplan-Meier survival curve showed that a higher expression of miR-141-3p positively corelated with a poorer prognosis. Combining the predicted targets and downregulated genes in EC, we obtained 271 target genes for miR-141-3p in EC. Two potential targets, PPP1R12A and PPP1R12B, were downregulated at both the mRNA and protein levels. This study indicates that the overexpression of miR-141-3p may play an important part in the carcinogenesis of EC. The overexpression of miR-141-3p may be a risk factor for the prognosis of patients with EC.

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.

Modified Circumcision Using the Disposable Circumcision Suture Device in Children: A Randomized Controlled Trial

OBJECTIVE

To evaluate and compare the surgical outcomes and complications of the modified circumcision using disposable circumcision suture device (device group) and the conventional dorsal slit circumcision (conventional group) in children.

METHODS

A total of 284 patients were randomized to either device group or conventional group. All patients were preoperatively assessed and evaluated at 4 weeks after surgery. The perioperative data and postoperative outcomes were compared between the 2 groups.

RESULTS

No statistical differences were observed in the average age and indications between the 2 groups preoperatively (P > .05). Compared with the conventional group, patients in the device group were shorter mean operative time, less blood loss, lower intraoperative and postoperative pain score, faster incision healing time and a higher satisfaction rate of penile cosmetic appearance (P < .01). Similarly, the incidences of complication were significantly lower in the device group than in the conventional group (4.3% vs 12.3%, P < .05).

CONCLUSIONS

The modified circumcision using disposable circumcision suture device is a simple, safe, faster, and effective procedure and may become the attractive alternative to the conventional technique for the children, with a relatively lower complication rate and better cosmetic results. With the improvement of disposable circumcision suture device, the modified circumcision using disposable circumcision suture device has the potential to be widely used in the world.
