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

ABSTRACT 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 the operation, at 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 were 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.

摘要
引言：为评估新型阴茎包皮环切缝合器（penile circumcision suturing devices，PCSD）与商环（Shang ring，SR）在成人包皮环切术中的安全性与有效性，本研究开展对照研究。
材料与方法：共纳入124名门诊患者，采用随机分组方案将其分为PCSD组（n=62）与SR组（n=62）。记录患者基线特征、手术时长、失血量、恢复正常活动时间（return to normal activities time，RNAT）、视觉模拟评分法（visual analogue scale，VAS）、瘢痕宽度、伤口愈合时间、美容效果及并发症发生情况。
结果：两组患者的失血量、恢复正常活动时间及并发症发生率均无显著差异。手术即刻、术后6小时及24小时的VAS评分组间比较差异均无统计学意义（P>0.05）。SR组术后瘢痕宽度显著大于PCSD组（P<0.01）；SR组患者伤口愈合时间显著长于PCSD组（P<0.01）；接受PCSD术式的患者对术后美容效果的满意度显著更高（P<0.01）。
结论：商环与PCSD均为成人男性包皮环切术安全有效的微创技术。相较于商环，PCSD具有术后切口愈合更快、伤口美容效果更佳的优势。
