In most instances, it is found that gastrointestinal cancers are detected at an advanced stage, which may indicate the need for a surgical intervention. However, the gastrointestinal endoscopic mucosal resection treatment,pioneered in Japan, was designed to detect the symptoms and manage the early signs of cancer in the gastrointestinal tract. TheEMR procedurehas gained wide acceptance as a therapy for different types of gastrointestinal lesions. It also includes treatment of esophageal squamous dysplasia, Barett's dysplasia, colorectal adenomas and early cancers. The endoscopic mucosal resection also offers an advantage of providing an accurate local staging of any disorders when compared with ablative therapies like photodynamic therapy, argon plasma coagulation, and radiofrequency ablation. The short,EMR surgerytechniques can be distinctly classified into suck and cut or suction process and lift and cut or non-suction process. In some cases, the gastroenterologists choose to apply both the procedures at the same time. In the suction technique, a submucosal injection is used for separating the muscular propria from the tumors or lesions in order to reduce chances of perforation. If the lesions have become invasive, a non-lifting sign may appear which would give a clear indication of a deeper invasion in the lesion. The colonic EMR is often executed by a non-suction process and a snare can help in resecting the polyp after giving the submucosal injection. The treatment procedure can result in complete cure.
