| [ Summary ] |
Endoscopic full‒thickness resection (EFTR) has attract ed attention as a minimally invasive treatment. However, in EFTR, several challenges have remained, such as the need for a flexible endoscopic full‒thickness suturing device and a counter traction device to create a surgical field to prevent gastrointestinal tract collapse. Pure EFTR is an extremely minimally invasive local resection approach to lesions by using the shortest distance via the mouth. EFTR is of two types, namely the exposed and non‒exposed types. With regard to infection and/or dissemination of tumor cells, non‒exposed EFTR is ideal. Gastroenterological endoscopists are expected to use this surgery if device development is advanced. EFTR could reduce patients' surgical stress, and medical and healthcare costs. Development of pure EFTR is considered as a socially urgent issue. |
