Endoscopic full-thickness resection of a stomach gastrointestinal stromal tumor using a dedicated full-thickness resection device
Endoscopic full-thickness resection (EFTR) is increasingly performed for the removal of GI subepithelial lesions (SELs). EFTR is minimally invasive compared with surgery but still can procure an adequate specimen for histologic assessment. A dedicated EFTR device (Ovesco Endoscopy, Tübingen, Germany) has been developed for the management of colorectal lesions.1 Data on its safety and efficacy for lesions in the upper GI tract are limited.2,3 In this case, we share our experience with the off-label use of a dedicated EFTR device for the removal of a GI stromal tumor (GIST) in the stomach.Tissue retractor system–assisted endoscopic submucosal dissection of a large rectal tumor with significant fibrosis from direct tattooing
Endoscopic tattooing directly into large dysplastic lesions is often performed for lesion identification before EMR or endoscopic submucosal dissection (ESD). Several case reports have demonstrated the difficulty of attempting endoscopic resection of previously tattooed lesions, primarily because of tattoo-induced submucosal fibrosis, inadequate lifting of the lesion, and obscuring of the dissection planes.1-3
