ENDOSCOPIC UNROOFING TECHNIQUE FOR GASTROINTESTINAL LIPOMAS (WITH A VIDEO)

Abstract

The endoscopic unroofing technique, an endoscopic treatment for gastrointestinal submucosal tumors, involves partial resection (approximately one-third to one-half) of the upper portion of the tumor using a snare, which allows the residual tumor to detach spontaneously over time. This method is associated with a low risk of complications such as bleeding or perforation. In the cases of gastrointestinal lipomas that can cause gastrointestinal bleeding or intussusception, unroofing after strangulation of the tumor base with a snare loop enables both histological diagnosis and curative treatment while also minimizing the risk of perforation. This technique is a minimally invasive procedure that can be performed safely within a short period of time.
