[Abnormally short frenulum induced by circumcision with the disposable circumcision suture device: Causes and improvement of the surgical method].

OBJECTIVE: To investigate the causes of abnormally short frenulum induced by circumcision with disposable circumcision suture device and the improvement of the surgical method. METHODS: We retrospectively analyzed the clinical data on 320 cases of phimosis or redundant prepuce treated from January 2020 to September 2020, including 160 children (group A) and 160 adults (group B), each further divided into an observation group (n = 80, groups A1 and B1) and a control group (n = 80, groups A2 and B2). The patients in groups A1 and B1 underwent circumcision by suture positioning at the frenulum with the disposable circumcision suture device, and those in groups A2 and B2 received conventional circumcision with the disposable circumcision suture device. We compared the operation time, incidence rate of abnormally short frenulum and Visual Analogue Scale (VAS) score at 6 hours after surgery among the four groups of patients. RESULTS: Statistically significant differences were observed between groups A1 and A2 in the operation time (12.00 ï¼»11.00, 13.00ï¼½ vs 8.50 ï¼»8.50, 9.00ï¼½ min, P < 0.05) and the incidence rate of abnormally short frenulum (0 vs 10%, P < 0.05) but not in the VAS score (3.00 ï¼»3.00, 4.00ï¼½ vs 3.00 ï¼»3.00, 3.75ï¼½, P > 0.05). Statistically significant differences were also found between groups B1 and B2 in the operation time (12.00 ï¼»11.00, 12.00ï¼½ vs 6.25 ï¼»6.00, 7.00ï¼½ min, P < 0.05) and the incidence rate of abnormally short frenulum (0 vs 7.5%, P < 0.05) but not in the VAS score (2.00 ï¼»2.00, 3.00ï¼½ vs 2.00 ï¼»2.00, 3.00ï¼½, P > 0.05). CONCLUSIONS: Abnormally short frenulum induced by circumcision with the disposable circumcision suture device is mainly attributed to ligation and fixation of the prepuce with the fixation band. Circumcision with the disposable circumcision suture device by suture positioning at the frenulum is a safe and effective method worthy of clinical promotion.
