Massive Cytoreduction Of Gastric Leiomyosarcoma Using Endoscopic Ultrasound Guided Radiofrequency Ablation (EUS-RFA)

A woman with gastrointestinal bleeding from gastric leiomyosarcoma was evaluated. Gastroscopy showed a 3 cm polypoid eroded mass in the stomach. EUS revealed an hypoechogenic transmural lesion. The tumor was punctured under EUS guidance with a 19G RFA (radiofrequency) needle. During ablation, a hyperechogenic halo was visible, releasing 50W. Different punctures were performed using fanning technique until became entirely hyperechogenic. After two RFA sessions, a 5mm residual erosion was observed. EUS-RFA procedures were performed on an outpatient basis, without complications and with good tolerance.

Conclusion EUS-RFA achieves a massive cytoreduction of gastric leiomyosarcoma in a simple and well tolerated manner.
