Novel modified endoscopic mucosal resection of large GI lesions (> 20 mm) using an external additional working channel (AWC) may improve R0 resection rate: initial clinical experience

Endoscopic Resection of Large Colorectal Lesions

The colorectal cancer (CRC) is one of the most common tumors in Western countries. It is the most common gastrointestinal tumor and it is estimated that between 5 and 6% of the population will suffer it along their lives. Colorectal cancer is a tumor in which it is possible to perform primary and secondary prevention. Primary prevention consists of all actions aimed to prevent the development o...

Endoscopic mucosal resection.

EMR has become an established therapeutic option for premalignant and early-stage GI malignancies, particularly in the esophagus and colon. EMR can also aid in the diagnosis and therapy of subepithelial lesions localized to the muscularis mucosa or submucosa. Several dedicated EMR devices are available to facilitate these procedures. Adverse event rates, particularly bleeding and perforation, a...

An Effective Technique for Endoscopic Resection of Advanced Stage Angiofibroma

Introduction: In recent years, the surgical management of angiofibroma has been greatly influenced by the use of endoscopic techniques. However, large tumors that extend into difficult anatomic sites present major challenges for management by either endoscopy or an open-surgery approach which needs new technique for the complete en block resection.   Materials and Methods: In a prospective obse...

Multi-camera system of the endoscopy: endoscopic mucosal resection for large gastric lesion using a novel 1-channel camera-hood.

Endoscopic procedures, such as endo− scopic mucosal resection (EMR) for large gastric lesions, are performed blindly [1, 2]. Precise snaring during EMR is impor− tant to carry en−block resection. However, this can be difficult to achieve in practice because it is impossible to perform snar− ing by complete observation. Although we can easily observe the proximal side of the lifting lesion, it i...
