Laparoscopic mediastinal approach for retrosternal gastric conduit cancer after esophagectomy

The prognosis of esophageal cancer has improved, but the incidence of gastric conduit cancer has increased. Gastric conduit cancer is difficult to treat because current treatment options are highly invasive; in particular, surgical procedures have high mortality and modality. Treatment through the retrosternal route usually requires sternotomy, which often causes lethal osteomyelitis. To prevent lethal complications and reduce invasiveness, we used the laparoscopic mediastinal approach. Here, we report a successful case using the laparoscopic mediastinal approach for the treatment of gastric conduit cancer through the retrosternal route. Despite a few concerns, this approach can be a treatment option for gastric conduit cancer through the retrosternal route.
