[Clinical observation of pre-suture ligation and suture knot positioning in single-operator circumcision with the stapler for children].

OBJECTIVE: To observe the clinical effects of pre-suture ligation and suture knot positioning in single-operator circumcision with the stapler. METHODS: Totally 120 six to fourteen years old children with phimosis or redundant prepuce were equally and randomly assigned to receive traditional single-operator circumcision with the stapler (group 1), single-operator circumcision with double suture knots for positioning the cutting plane with the stapler (group 2), or pre-suture ligation plus single-operator suture knot positioning circumcision with the stapler (group 3). We recorded and comparatively analyzed the operation time, intraoperative blood loss and hematoma, the number of residual suture knots, the patients' satisfaction with foreskin reservation, sutured frenulum and incision aesthetics, and the rates of surgical conversion, severe postoperative dysuria, severe wound exudation and perioperative anxiety of the parents and surgeon. RESULTS: Statistically significant differences were observed among the three groups in the operation time, intraoperative blood loss, incidence of intraoperative hematoma, number of residual suture knots, the patients' satisfaction with foreskin reservation, sutured frenulum and incision aesthetics, and the rates of surgical conversion, severe postoperative dysuria, severe wound exudation and perioperative anxiety of the parents and surgeon (P < 0.05). Compared with group 1, group 3 showed obviously less operation time and intraoperative blood loss and lower incidence of intraoperative hematoma, number of residual suture knots and rates of surgical conversion and perioperative anxiety of the parents and surgeons, and higher rates of patients' satisfaction with foreskin reservation, sutured frenulum and incision aesthetics. The intraoperative blood loss, incidence of intraoperative hematoma, and the rates of severe postoperative dysuria, severe wound exudation and perioperative anxiety of the parents and surgeon were lower in group 3 than in group 2. CONCLUSION: Pre-suture ligation plus single-operator suture knot positioning circumcision with the stapler helps reduce the operation time, intraoperative blood loss, incidence of intraoperative hematoma, number of residual suture knots and rates of surgical conversion and perioperative anxiety of the parents and surgeon, and increase the patients' satisfaction with foreskin reservation, sutured frenulum and incision aesthetics.
