In our experience patients undergoing circumcision are mostly concerned about pain and penile appearances. We conducted a prospective randomized trial to assess the beneifts of a new disposable circumcision suture device (DCSD). A total of 942 patients were equally divided into three groups (conventional circumcision, Shang ring and disposable suture device group). Patients in the DCSD group were anesthetized with compound 5%lidocaine cream, the others with a 2%lidocaine penile block. Operation time, intra-operative blood loss, incision healing time, intra-operative and post-operative pain, the penile appearance and overall satisfaction degree were measured. Operation time and intra-operative blood loss were signiifcantly lower in the Shang ring and suture device groups compared to the conventional group (P<0.001). Intra-operative pain was less in the suture device group compared with the other two groups (P<0.001);whereas post-operative pain was higher in the conventional group compared to the other two groups (P<0.001). Patients in the suture device (80.57%) and Shang ring (73.57%) groups were more satisifed with penile appearances compared with the conventional circumcision group (20.06%, P<0.05). Patients in suture device group also healed markedly faster than the conventional group (P<0.01). The overall satisfaction rate was better in the suture device group (78.66%) compared with the conventional (47.13%) and Shang ring (50.00%) groups (P<0.05). The combination of DCSD and lidocaine cream resulted in shorter operation and incision healing times, reduced intra-operative and post-operative pain and improved patient satisfaction with the cosmetic appearances.
