Submucosal Endoscopic Tumor Resection

Endoscopic resection of gastric submucosal tumor

Submucosal tumors (SMT) are occasionally found in the esophagus and stomach during diagnostic endoscopy with reported incidence of 0.36% (1). There was no consensus on the management of incidental SMT as the histopathologic nature of such tumor is often uncertain. Attempt in obtaining adequate samples for tissue diagnosis is associated with risk of hemorrhage and perforation. The reported diagn...

Submucosal tunneling endoscopic resection of a gastric gastrointestinal stromal tumor.

A 64-year-old man was admitted to our hospital for endoscopic resection of a gastrointestinal stromal tumor (GIST) of the gastric antrum. The submucosal tumor had been previously observed during an esophagastroduodenoscopy, which revealed a protruded lesion in the greater curve of the gastric antrum. The subsequent endoscopic ultrasound showed that the tumor was large (20mm), arose from the mus...

Endoscopic Resection for Small Rectal Neuroendocrine Tumors: Comparison of Endoscopic Submucosal Resection with Band Ligation and Endoscopic Submucosal Dissection

Background and Aims. There is no consensus so far regarding the optimal endoscopic method for treatment of small rectal neuroendocrine tumor (NET). The aim of this study was to compare treatment efficacy, safety, and procedure time between endoscopic submucosal resection with band ligation (ESMR-L) and endoscopic submucosal dissection (ESD). Methods. We conducted a prospective study of patients...

Endoscopic resection of small-bowel submucosal nodule.

The options for management of submucosal nodules in the small bowel are limited. A 67-year-old woman presented for evaluation after positive findings from fecal immunochemical testing. Colonoscopy showed a 2-cm submucosal nodule in the terminal ileum. Superficial biopsies from the lesion were unrevealing. Over-thescope clip (OTSC)-assisted resection was planned. An OTSC (size 12/6, type gc) was...
