SUBMUCOSAL TUNNELING ENDOSCOPIC RESECTION (STER) FOR A GIANT ESOPHAGEAL LEIOMYOMA

Introduction STER is recommended for esophageal lesions < 4 cm diameter. Resection of larger lesions is technically challenging. This video-case demonstrates technical nuances of performing STER for large leiomyomas.

Patients and Methods 37/Male presented with dysphagia. CT scan, EGD and EUS-FNA revealed giant esophageal leiomyoma (6 x 2.5 × 4 cm) in MP layer at 20 cm.

Results Procedure time 210 min. No adverse events. Contrast swallow confirmed absence of luminal leak. At one-month follow up, EGD demonstrated healthy mucosal scar. No dysphagia noted.

Conclusions STER is feasible and safe for giant esophageal SET’s. Intracorporeal morcellation of tumor before delivering specimen simplifies procedure.
