Endoscopic enucleation of large esophageal leiomyomas

Thoracoscopic and Laparoscopic Enucleation of Esophageal Leiomyomas

Although infrequent, esophageal leiomyomas are the most common benign intramural tumors of the esophagus. As malignant potential is not a concern in these lesions, they represent ideal candidates for an organ-preserving approach. Due to their well-circumscribed growth, a minimally invasive approach should be pursued in almost all patients. We present our recent techniques and results associated with totally minimally invasive thoracoscopic and laparoscopic approaches to resection of esophageal leiomyomas. These approaches require technical expertise but can be accomplished with a short learning curve.

Successful en bloc resection of papillary neuroendocrine tumors by duodenoscope using endoscopic submucosal dissection method

Neuroendocrine tumors (NETs) of the main duodenal papilla are rare. Surgery such as pancreaticoduodenectomy is traditionally recommended as the standard treatment for papillary neuroendocrine tumors. Endoscopic resection is increasingly used for treating these lesions. However, resection of papillary NETs using endoscopic submucosal dissection (ESD) technique was scarcely reported. In this paper, we report a patient with neuroendocrine tumor of the main duodenal papilla originating from the muscularis propria on EUS underwent successful endoscopic submucosal dissection using a duodenoscope. With 6-month followed up, no stenosis of bile and pancreatic ducts or relapse of tumor occurred.
