Abstract:Objective To compare the effect of flap transfer combined with modified Devine or Brisson procedure in correction of concealed penis in children who were mistakenly circumcised.Methods Data of 92 children with concealed penis who were mistakenly circumcised in our hospital from September 2020 to January 2023 were prospectively selected and divided into the control group and the study group by the random number table method, with 46 cases in each group. The control group received flap transfer combined with modified Devine surgery, and the study group received flap transfer combined with modified Brisson surgery. All of the children were followed up for 6 months. The operation, pain, perioperative stress response, postoperative recovery, complications and family satisfaction were compared between the two groups.Results There was no significant difference in the operative duration between the two groups (P > 0.05), and the amount of intraoperative blood loss in the study group was lower than that in the control group (P < 0.05). The Face, Legs, Activity, Cry, Consolability (FLACC) scores 4 h, 12 h and 24 h after the surgery were compared between the two groups, and the results showed that the FLACC scores were different among the time points (P < 0.05) but not between the two groups (P > 0.05), and that the change trends of FLACC scores were not different between the two groups (P > 0.05). There was no significant difference in the levels of adrenaline (Adr) and cortisol (Cor) between the two groups before and 24 h after surgery (P > 0.05). The postoperative penile length of the two groups was higher than that before surgery (P < 0.05), and the postoperative penile length and the increased penile length of the study group were higher than those of the control group (P < 0.05). There was no significant difference in the duration of postoperative preputial edema between the two groups (P > 0.05). There was no significant difference in the overall incidence of complications between the two groups (P > 0.05). The family satisfaction in the study group was higher than that in the control group (P < 0.05).Conclusions Flap transfer combined with modified Devine or Brisson is safe and effective for correction of concealed penis in children who were mistakenly circumcised, but flap transfer combined with modified Brisson is more advantageous in extending the penile length of children and improving the family satisfaction.
