Endoscopic En-Bloc Resection of Lipoma of the Distal Biceps Tendon.

Lipomatas can develop anywhere in the body and are rarely found within tendon sheaths. Lipomas of the tendon sheath may present with pain, mechanical symptoms, neurologic symptoms, and tendon rupture. Classically, lipomas are resected via open approach, which may result in a lengthy disfiguring surgical scar. Endoscopic en-bloc tumor resection is a minimally invasive approach and can provide a whole-block specimen for histologic examination and reduce the risk of seeding of residual tumor. The purpose of this Technical Note is to describe the details of endoscopic en-bloc resection of lipoma of the distal biceps tendon.
