Wung Procedure

The Wung procedure is a modified surgical technique based on the classic Nuss procedure, which has been meticulously adapted to overcome its inherent limitations and risks. Although it utilizes the lever principle of the Nuss procedure, the Wung procedure introduces significant differences in operative details.

In order to avoid the common issues and risks of the Nuss procedure, such as heart injury during the placement of the bars, insecure fixation of the bars

leading to their displacement, or poor wound healing after surgery, Dr. Wenlin Wang has pioneered numerous improvements to the operative details. Complementing these improvements, he has also engineered a variety of innovative techniques such as “Wang Technique” for bar fixation. These innovative refinements not only simplify the surgical steps, but also significantly reduce the difficulty and risk of the operation, resulting in lessened patient trauma, accelerated recovery, and a markedly decreased probability of postoperative complications.

Make an incision of about 2 cm on each side of the chest wall.
Use the surgical strip and a guiding catheter to place 2 pre-shaped bars into the chest cavity (This step can effectively prevent damage to the heart).
Turn over the bars to elevate the depressed chest wall.
Secure both ends of the bars to the ribs on either sides of the chest wall, suture the incisions, and conclude the surgery.
