FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to endoscopic intraluminal surgery, oncology. The dissection of the mucous membrane is carried out behind the marks of the boundaries of the formation, retreating from them 5 mm. A dental floss is fixed to one of the jaws of the clip. The thread fixed to the clip branch is clipped to the edges of the dissected mucosa after 1.0-1.5 cm at three or more points along the perimeter of the dissected mucosa, while the thread from the tumor is movably fixed to the opposite wall of the organ. The thread is tightened, followed by traction of the dissected mucosa, after which the submucosal layer is dissected with an endoscopic knife, followed by removal of the resected tumor.

EFFECT: method is simple and economical, allows to increase the efficiency of tumor traction, reduce the operation time and reduce the number of intraoperative and postoperative complications, such as bleeding, perforation, applicable in technically difficult cases: submucosal fibrosis, complex anatomical localization - the esophagus, lesser and greater curvature of the body of the stomach , the right half of the colon, bends of the colon, recurrence of tumors after endoscopic removal due to the fixation of the thread on the tumor at additional points, which ensures the rise of the formation from several sides at once.
