Robotic-assisted Resection of a Diaphragmatic Metastasis of a Gastrointestinal Stromal Tumor

Abstract

Gastrointestinal stromal tumors (GISTs) are relatively rare mesenchymal tumors. The treatment of these tumors has drastically changed based on molecular treatment methods, namely tyrosine kinase inhibitors, which have led to impressive survival benefits. While medical management has enhanced patient outcomes, surgery is still the standard of care for stable, completely resectable primary tumors or metastases that are >2 cm. This case presents the resection of a diaphragmatic metastasis of a tyrosine kinase inhibitor-controlled GIST in a 51-year-old male. The surgery was collaboratively approached from both the thoracic and abdominal cavities, utilizing the da Vinci robotic system. Prior data is limited regarding patient outcomes after robotic-assisted resection of GISTs. However, small case series have shown it to be a safe and effective surgical option. Our patient's quick recovery and return to normal function demonstrate the successful use of robotic-assisted surgery for GIST resection.
