[Experience with Wang procedure for treatment of pectus excavatum in young children].

Objective: To review the experience with Wang procedure for treatment of pectus excavatum in young children.
Methods: The clinical data of 21 children with a mean age of 3.3 ± 1.1 years (ranging from 1.5-6 years) undergoing Wang procedure for pectus excavatum were analyzed. A longitudinal incision (1 to 2 cm) was made in the front of the xiphoid, and two tunnels were created using steel bars beneath the muscles on two sides of the chest wall. The fibrous tissue between the diaphragm and the sternum was dissociated, and the steel wires were sutured through the deformed chest wall. After the steel bar was placed in the tunnels, the wires were pulled and fixed in the middle of the bar, and the incision was sutured.
Results: All the operations were performed using 3 wires and 1 steel bar. The operation time was 25 to 51 (38.1 ± 9.6) min with an intraoperative bleeding volume of 5 to 10 (7.1±1.5) mL. The time of hospitalization of the patients ranged from 6 to 10 days (mean 8.1±1.3 days). In all the patients, the incision healed smoothly without serious pain or obvious complications. All the patients were followed up for 1 to 13 months after the operation. During the follow- up, no recess recurred and no such complications as bar displacement or transposition occurred. According to the evaluation criteria after pectus excavatum operation, 13 cases had a total score of 9, and 8 had a total score of 8. The overall effect was satisfactory, and there were no cases rated as basically satisfactory or unsatisfactory.
Conclusions: Wang procedure is a good option for treatment of pectus excavatum in young children.
