Objective To observe the clinical effect of modified four-stage method silicone washer circumcision suture device for circumcision.Methods The clinical data of 216 patients who attended our hospital and underwent circumcision from August 2020 to August 2023 were retrospectively analysed.They were divided into two groups according to the use of different circumcision sutures,112 cases in the observation group(modified four-stage method with silicone washer circumcision suture)and 104 cases in the control group(without silicone washer circumcision suture),and the safety,effectiveness and surgical complications of the two groups were compared.Results The rates of circumcision bleeding,late-onset haematoma,pain rate during circumci-sion change at 1 d,3 d and 7 d after surgery,suture staple dislodgement rate at 4 weeks postoperatively and manual staple removal rate were compared between the two groups,and the differences were statistically significant(P<0.05).Conclusion Compared with the disposable circumcision suture without silicone washer,the modified four-stage method with silicone washer disposable circumcision suture has the advantages of less surgical bleeding,low incidence of delayed haematoma,mild postoperative circumcision pain,high rate of postoperative 4-week silicone washer stapling and low rate of manual stapling,which is worthy of clinical promotion and application.
