Esophageal cancer with severe funnel chest treated by simultaneous funnel chest surgery and thoracoscopic esophagectomy: a case report

BACKGROUND: Funnel chest is the most common chest deformity, occurring in 0.06–0.3% of the general population. When it occurs concomitantly with esophageal cancer, it hinders intrathoracic surgery that is necessary for treatment. Although there are a few reports of esophagectomy performed in patients with funnel chest, simultaneous treatment of esophageal cancer and funnel chest with funnel chest surgery (Nuss method) and esophagectomy has not been reported. We report the first case of advanced esophageal cancer complicated by severe funnel chest that was treated using the Nuss method and radical thoracoscopic esophagectomy. CASE PRESENTATION: A 59-year-old man was diagnosed with advanced thoracic esophageal cancer and severe funnel chest. Because his sternum was almost attached to the vertebral bone, thereby creating a narrow space in the mediastinum, esophageal surgery was expected to be complicated. After the patient underwent neoadjuvant chemotherapy, we used the Nuss method to reconstruct the chest and widen the mediastinum. Subsequently, radical thoracoscopic esophagectomy was performed with the patient in the left decubitus position without any difficulty, and the postoperative course was uneventful. CONCLUSION: Simultaneous funnel chest surgery (Nuss method) and thoracoscopic esophagectomy with the patient in the left decubitus position are recommended for esophageal cancer patients with severe funnel chest.
