Successful Robot-Assisted Surgery for Advanced Metachronous Cancer in a Gastric Conduit after Esophagectomy: A Case Report

抄録

The incidence of gastric tube cancers has increased due to improved survival rates in patients after esophagectomy. However, the optimal surgical approach for gastric tube cancer remains controversial. Here, we report the case of a 70-year-old man with advanced gastric cancer arising from a retrosternally placed gastric conduit, 12 years after thoracic esophagectomy for esophageal cancer. Total resection of the gastric conduit was performed with robotic assistance. Although the working space was limited, secure resection was possible. Continuous en bloc mobilization was achieved with neck dissection, and reconstruction was performed via the same retrosternal route using the ileocolon. The patient was discharged on the 14th postoperative day without any adverse events. Robot-assisted surgery can overcome the technical limitations of laparoscopic mediastinal surgery and has advantages such as improved ergonomics, comfort, and elimination of hand tremors, and therefore may be an option for future minimally invasive surgeries.
