Abstract:
Objective:To investigate the clinical effect of the combination of distal subcutaneous buried suture, to reduce local tension, and electron irradiation for the treatment of keloid.
Methods:From May 2014 to July 2016, nine female patients with recurrent keloid in torso were treated by above method. After eligibility was confirmed, surgery was performed to completely excise the keloid. An extensive subcutaneous segregation was made around the incision. The 4-0 PDS Ⅱ sutures were buried in the subcutaneous layer, 1.5 cm from the edges of incision, 1 cm apart from each other, and were knotted from both ends of the incision to the center. The normal skin on both sides of the incision were pulled toward the center, and completely relaxed without tension. An interrupted subcutaneous suture was made with a 4-0 Coated VICRYL absorbable suture, and a continuous intradermic suture was made using a 5-0 Coated VICRYL absorbable suture. Superficial electron irradiation was implemented 10-22 h postoperatively. The dose of radiation was 4 Gy each time, with the frequency of 4-5 times in 4-7 days, once a day, and the total dose was up to 16-20 Gy.
Results:The average follow-up was 15 months (12-18 months). Based on the three-stage classification system formulated by Dr. Cai, an asymptomatic flat and soft scar without recurrence up to 12 months was classified as cured (excellent). All the patients in this series met the criterion of cure.
Conclusions:The distal subcutaneous buried suture technique, pulling bilateral normal skin toward the center with a PDS Ⅱ suture, could completely relax the skin around the incision, and maintain a prolonged tension-free state, combination therapy of electron irradiation and surgery may reduce the inflammation during the healing process, and result in a dramatic inhibition of the recurrent of keloids after surgery.
