抄録

Strip biopsy, which is an endoscopic resected technique for sessille or flat type lesion is possibly applied to the resection for the colonic submucosal tumors such as lymphangioma or lipoma. In conventional strip biopsy, saline is firstly injected into the submucosa around a lesion in order to elevate the target lesion from the submucosal layer and then a snare device is placed around the elevated mass which is resected by use of electrocoagulation. Only local application with saline, however, is not able to make clear a border line between the target lesion and its surrounding mucosa especially in resection of submucosal tumors. Inadequate positioning of snare device is sometimes resulted in complications such as perforation or incomplete resection of the tissue. Instead of saline, we used the saline containing methylene blue (SCMB) to get the clear border of a tumor or correct snare position. Based on this technique, we performed safely 4 complete resections of colonic submucosal tumors including 2 lipoma and 2 lymphangioma.
