Latissimus-sparing thoracotomy in the pediatric patient: a valuable asset for thoracic reconstruction.

The traditional posterolateral thoracotomy involves division of the latissimus dorsi muscle (LD). While the division results in no functional disability, it does negate the potential for possible future thoracic reconstruction if required in individual cases (eg, bronchopleural fistula, empyema, etc). A latissimus-sparing thoracotomy (LST) mobilizes the muscle dorsad and does not compromise the operation. Thus, the ipsilateral LD can be used when chest wall reconstruction is required. This option has been used frequently for adults; however, its use in children has not been extensively documented. Microvascular anastomoses for a contralateral LD free-flap may be tenuous in the small vessels of the child; thus, reconstruction using the ipsilateral LD could be beneficial and safer. The feasibility of LST has not been established with regard to the chest of the child. The authors present three pediatric thoracic cases that illustrate the value of this procedure, and discuss different situations in which latissimus-sparing thoracotomy is advantageous.
