Colorectal endoscopic submucosal dissection (ESD) still remains a technically difficult procedure. The maintenance of tissue tension and good submucosal exposure during dissection is one of the most important factors for an effective and safe dissection. Although various traction methods have been developed, traction by gravity is one of the most useful method for colorectal ESD. Traction using...

Gastrointestinal subepithelial tumors (SETs) are generally found during endoscopy and their incidence has gradually increased. Although the indications for the endoscopic treatment of patients with SETs remain to be established, the feasibility and safety of endoscopic dissection, including the advantages of this method compared with surgical treatment, have been validated in many studies. The ...

In the last years, a distinctive interest has been raised on large polypoid and non-polypoid colorectal tumors, and specially on flat neoplastic lesions ≥20 mm tending to grow laterally, the so called laterally spreading tumors (LST). Real or virtual chromoendoscopy, endoscopic ultrasound or magnetic resonance should be considered for the estimation of submucosal invasion of these neoplasms. Le...

Aim: The aim of this study was to examine the safety and efficacy of endoscopic submucosal dissection (ESD) for early gastric cancer based on approximately 10 years’ experience. Methods: Endoscopic submucosal dissection was performed in 1272 patients with early gastric cancer (1657 lesions). We examined en bloc resection rate, curative resection rate, local recurrence rate, procedure time, and ...

Early esophageal cancer is defined as a tumor invading the mucosa with or without lymph node or distant organ metastasis. In the current guidelines for early esophageal cancer, absolute indication for endoscopic resection include lesions limited to the epithelium or lamina propria mucosa not exceeding two-thirds of the circumference, and relative indications include lesions limited to the muscu...

Endoscopic submucosal dissection (ESD) is a minimally invasive technique developed by Japanese endoscopists that allows one-piece endoscopic removal of early malignant lesions in the gastrointestinal tract. There is now a large and ever-increasing number of reports worldwide, and in the West use of this technique is on the increase. New materials and techniques have been developed to improve th...
