[Effectiveness of modified Brisson surgery in treatment of severe concealed penis].

Objective: To discuss the effectiveness of modified Brisson surgery in treatment of the severe and obviously obese concealed penis.
Methods: A clinical data of 96 boys with severe concealed penis, of 53 cases combined with obviously obese, who were treated by modified Brisson surgery between January 2014 and August 2016, was retrospectively analysed. The children ranged in age from 1 year to 11 years and 9 months, with an average of 5 years and 3 months. The median longitudinal incision of the penis scrotum was used instead of the wedge-shaped skin incision at the junction of the penis and scrotum, which could completely expose the surgical field; fully release and removal of the abnormal meat membrane and fascia around the penis were performed; the propulsion and rotating flaps match the inner sheath of the foreskin was used to completely remove skin stenosis. Postoperative effectiveness was evaluated by Boemers standard.
Results: All the incisions healed by first intention and no infection or necrosis of the foreskin flap occurred. Ninety-three cases were discharged from hospital after operation and followed up 1 year to 3 years and 6 months, with an average of 2 years and 4 months. Scrotal hematoma occurred in 2 cases within 48 hours, penile skin edema occurred in 5 cases, and scar hyperplasia in the penis scrotal corner incision occurred in 1 case at 1 month after operation. Postoperative exposure of the penis was good in 90 cases; there was no retraction of the penis in the upright position and sitting position; the family members were satisfied with the appearance of the penis. The penis were partially retracted in 3 cases, that affected the appearance of the penis during the sitting position.
Conclusion: The modified Brisson surgery is one of the most effective methods to treat the severe and obviously obese concealed penis, with satisfactory effectiveness and less complication.
