Wenlin procedure for treatment of pectus carinatum

Abstract

Pectus carinatum is a common thoracic deformity, and its treatment has a long history. The early operation was open operation. With the emergence of the concept of minimally invasive surgery in clinical practice, minimally invasive surgery of pectus carinatum has gradually become the mainstream in its treatment. The earliest minimally invasive operation was Abramson procedure. This kind of operation has certain effect, but it also has many disadvantages. In order to eliminate its disadvantages, we designed a new operation, Wenlin procedure. In essence, this operation is a template plastic surgery. Because of the special design, it has obvious advantages. So far, this operation has been widely used in China. Clinical experience shows that this operation is safe, simple and practical. However, like all other operations, this operation also has defects. In the future use process, its defects need to be continuously discovered and improved.

Groove chest: An independent thoracic deformity

“…Take protrusion deformity as an example, in the past, all protrusion deformities can be treated with open operation. However, when minimally invasive surgery, such as Abramson procedure [22] and Wenlin procedure [13,14] , are used for treatment of typical pectus carinatum, those protrusion deformities that cannot use these operations, such as Wenlin chest, have to be noticed, and should have a new name [19,20] .…”

“…The method we designed is a comprehensive surgical method. First, Wung procedure [12] was performed to change the groove chest into saddle chest, and then Wenlin procedure [13][14][15][16] was performed to eliminate the depression on both sides. In this way, the deformity can be completely corrected (Fig.…”

Minimally invasive surgery of Wenlin chest

“…After full preparation, the operation was performed under general anesthesia. The operation included two basic procedures, namely Wenlin procedure [10][11][12] and Wung procedure [13,14] . Two small incisions were performed on both sides of the chest wall respectively.…”

Acute angle deformity: A special local lesion of chest wall bone structures

“…Since Nuss procedure appeared, the treatment of thoracic deformity has entered the era of minimally invasive surgery [4] . All the operations for the treatment of thoracic deformity are divided into two categories: one is for depression deformity, including Nuss procedure [4] , Wang procedure [5][6][7][8][9] and Wung procedure [10,11] ; the other is for protrusion deformity, including Abramson procedure [12] and Wenlin procedure [13][14][15][16][17][18] . From the nature of surgery, Nuss procedure [4] and Abramson procedure [12] are mechanical external force plastic surgery, while Wang procedure and Wenlin procedure are template plastic surgery [1,2] .…”
