Mucosectomy - Injection to Lift the Lesion, Part 1

Using endoscopic suction or saline injection to lift the lesion -bearing mucosa. Fitting a transparent cap on the tip of the endoscope can enhance the lifting power of suction. The cap has a rim to hold an open mucosectomy snare. Endoscopic therapy has been employed for early-stage lesions in an attempt to avoid the high morbidity and mortality associated with current curative procedures such as esophagectomy. Drawing up by Suction and Cutting This brings together several techniques which all necessi-tate drawing up the lesion by suction before the resection. This drawing by suction may be carried out with the aid of a plastic hood or of an elastic ligature unit. Since the introduction of snare resection of pedunculated polyps (snare polypectomy) in the early 70's, many different devices and procedures were developed: strip-off biopsy, strip biopsy, EMR with cap, and EMR with ligation.
