Insights
The Wang procedure effectively treats pectus excavatum in young children. This minimally invasive surgery shows satisfactory results with no recurrences or complications in follow-up studies.
Area of Science:
- Pediatric Surgery
- Thoracic Surgery
- Congenital Malformations
Background:
- Pectus excavatum is a congenital chest wall deformity affecting young children.
- The Wang procedure offers a surgical approach for correcting pectus excavatum.
Purpose of the Study:
- To evaluate the efficacy and safety of the Wang procedure for treating pectus excavatum in pediatric patients.
- To review the clinical outcomes and complications associated with the Wang procedure in young children.
Main Methods:
- Analysis of clinical data from 21 children (mean age 3.3 years) who underwent the Wang procedure.
- Description of the surgical technique involving a longitudinal incision, creation of tunnels, and placement of steel wires and a bar.
- Assessment of operative time, blood loss, hospitalization duration, and follow-up outcomes.
Main Results:
- Operations were short (mean 38.1 min) with minimal blood loss (mean 7.1 mL).
- Hospitalization averaged 8.1 days with smooth wound healing and no major complications.
- Follow-up (1-13 months) showed no recurrence or implant displacement, with satisfactory outcomes in all patients.
Conclusions:
- The Wang procedure is a viable and effective treatment for pectus excavatum in young children.
- The technique demonstrates a favorable safety profile and excellent clinical results in the pediatric population.
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.

Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
