Retrograde esophageal endoscopic submucosal dissection through a gastrostomy

Gastric endoscopic submucosal dissection through a gastrostomy using a newly developed thin endoscope

“…Although the newly developed endoscope has a large working channel of 3.2 mm and offers wide angles (up 210°; down 160°), its small width of 7.9 mm enabled efficient ESD to be performed through the gastrostomy without dilation 1 .…”

“…A 76-year-old man underwent follow-up endoscopy after undergoing curative endoscopic submucosal dissection (ESD) for esophageal cancer [1]. He had a past history of advanced pharyngeal cancer, which had been treated with chemoradiotherapy, and had a percutaneous endoscopic gastrostomy because of persistent trismus (▶ Fig.…”

“…The final pathologic diagnosis was a 6 × 6-mm, 0-IIc, well-differentiated tubular adenocarcinoma, pT1a, pUL0, ly0, v0, pHM0, pVM0. Although the newly developed endoscope has a large working channel of 3.2 mm and offers wide angles (up 210°; down 160°), its small width of 7.9 mm enabled efficient ESD to be performed through the gastrostomy without dilation [1].…”

Efficacy and Safety of Endoscopic subserosal dissection Treatment for Gastrointetinal submucosal Tumors in the Upper Gastrointestinal Tract

“…Endoscopic full-thickness resection Submucosal tumors (SMT) are solid tumors originating from the tissue below the epithelium of the digestive tract, common are leiomyoma, stromal tumor, cyst, neuroendocrine tumor, ectopic pancreas, lipoma, etc [1][2][3] . With the progress of endoscopic technology, especially the advancement of ESD-related technologies, more and more early digestive tumors have opportunity for endoscopic therapy [4] . Endoscopic submucosal execution (endoscopic submucosal execution, ESE) has been used in the minimally invasive treatment of gastric submucosal tumors.…”
