Abstract: Objective To assess the clinical efficacy of disposable circumcision suture device (DCSD) in children receiving circumcision. Methods Children with phimosis and redundant prepuce undergoing circumcision in our hospital were prospectively enrolled in this study hospital and randomized into DCSD group and conventional circumcision (CC) group. A total of 236 boys were enrolled, including 132 in DCSD group and 104 in CC group. The use of local anesthesia, operation time, intraoperative blood loss, intraoperative and postoperative pain scores, penile appearance satisfaction rates, postoperative complications, healing time of the incision, and the overall satisfaction rate were compared between the two groups. Results Compared with CC group, DCSD group had a significantly higher proportion of local anesthesia (P<0.01), shorter operative time (P<0.001), less intraoperative blood loss (P<0.001), lower intraoperative and postoperative pain scores (P<0.001), higher penile appearance satisfaction rates (P=0.03), less postoperative complications (P=0.04), shorter healing time (P<0.001), and a higher overall satisfaction rate (P<0.005). Conclusion The use of DCSD can shorten the operative time and is associated with good tolerance of local anesthesia, less pain, quick recovery, and higher penile appearance satisfaction rates in children receiving circumcision.
