[Knot-free suture and frenulum positioning combined with application positioning using a disposable circumcision suture device in circumcision].

To explore the effect of knot-free suture and frenulum positioning combined with application positioning (KFS-FP + AP) in circumcision using a disposable circumcision suture device. We retrospectively analyzed the clinical data on 160 cases of circumcision for phimosis or redundant prepuce by KFS-FP + AP (the observation group, n = 80) or by routine circumcision (the control group, n = 80) with a disposable circumcision suture device from February 2021 to December 2021. We recorded the operation time, incidence of frenulum breve, incidence of frenulum dislocation, and Visual Analog Scale (VAS) scores at 6 hours after surgery, and compared them between the two groups of patients. The operation time was longer in the observation than in the control group (8.00 ［8.00, 9.00］ min vs 5.00 ［5.00, 5.00］ min), and the incidence rates of frenulum breve (0 vs 8.75%, P < 0.05) and frenulum dislocation (0 vs 7.5%, P < 0.05) significantly lower in the former than in the latter group. There were no statistically significant difference in the VAS scores between the observation and the control groups (2.60 ［2.00, 3.00］ vs 2.55 ［2.00, 3.00］, P > 0.05). KFS-FP + AP with a disposable circumcision suture device is a safe and effective method of circumcision, with high satisfaction of the patients and worthy of clinical promotion.
