Esophagoplasty for congenital defect (plastic repair or reconstruction), thoracic approach; without repair of congenital tracheoesophageal fistula

Esophagoplasty is a surgical procedure aimed at the plastic repair or reconstruction of the esophagus, particularly in cases of congenital defects. This procedure is performed through a thoracic approach, typically utilizing a right posterolateral thoracotomy. During the operation, the surgeon makes an incision in the skin and extends it through the underlying soft tissues to access the thoracic cavity. The scapula is retracted to facilitate entry into the thorax while ensuring that the pleura, the membrane surrounding the lungs, remains undisturbed. The procedure involves retropleural dissection, where the lung is retracted to expose the esophagus adequately. The mediastinal pleura may be opened as necessary to provide full visibility of the defect in the esophagus. In the context of CPT® Code 43313, it is important to note that the esophageal defect being addressed does not involve a tracheoesophageal fistula, which is a connection between the trachea and esophagus that can complicate surgical repair. The surgeon meticulously dissects the esophagus free from surrounding tissues to inspect and repair the defect. The muscular wall of the esophagus at the defect site is carefully examined and debrided if required, while the mucosal defect is exposed and trimmed back to healthy tissue. The mucosal tissue is then inverted and sutured, followed by the placement of a second layer of sutures in the muscular wall to ensure a robust repair. To enhance the strength of the repair, microvascular anastomosis of an intercostal muscle flap may be utilized. Prior to closing the thoracic cavity, a nasogastric feeding tube is inserted to facilitate postoperative nutrition, and a chest tube is placed in the retropleural space to manage any potential fluid accumulation. Finally, the thoracic incision is closed, completing the esophagoplasty procedure.
