Endoscopic Mucosal Resection (EMR)

Endoscopic mucosal resection (EMR) is a method of removing superficial lesions from the gastrointestinal (GI) tract. In the colon and rectum, it is used to remove precancerous lesions as well as select cases of early submucosal cancer. In this chapter, I will discuss the indications and contraindications of EMR from a Japanese perspective, describe the basic techniques of EMR and some variations of the technique, and discuss tips and tricks as well as pitfalls of the procedure.
