MULTI-EMRL AND RECONSTRUCTION OF THE RESECTED SPECIMENS-EXPERIMENTAL STUDY FOR THE PURPOSE OF ESTABLISHING RELIABLE TECHNIQUE AND IT'S CLINICAL USE

Abstract

We experimented basic examination in 5 mongrel dogs to establish reliable multi-EMRL procedure and useful reconstruction procedure of the resected specimens. It is most effective and reliable technique that, at first EMRL, we applied the cap (EVL device) to both front and one side markes and resect mucosa about ×20 mm in size by 3 times EMRL. The depth of the ulcer base induced by multi-EMRL, even at the borderline between the two resected mucosa, reached submucosal layer (sm3). And it is very effective reconstructed procedure of the specimens by piecemeal resection that clip as mark is punched on the ligated mucosa. These results indicated that multi-EMRL procedure using clip may play a effective and reliable role in the division of mucosal resection.
