The sequence of events leading to the development of colorectal cancer, currently the third most common malignancy in Western countries, is effectively disrupted by the resection of its precursor lesions. Colonoscopy is the mainstay in lesion detection, and endoscopic polypectomy is the conventional therapeutic response for the overwhelming majority of identified polyps. Approximately 2% of lesions are larger (>20 mm) and are laterally spreading lesions (LSLs). EMR is considered the standard of care for the majority of these because it has been proved to be safer, less resource-intensive, and less expensive than surgery.
Norman Barrett first described Barrett ’s esophagus (BE) as salmon-colored mucosa lining the distal esophagus, but little did he know that this entity would be a topic of great curiosity and research in gastroenterology for its definition, for its diagnosis, and especially for its role as a premalignant condition for esophageal adenoca rcinoma (EAC).1 Over the years, the incidence of EAC has risen severalfold. Patients often present late, and by the time the diagnosis is established, the disease is advanced, with a poor prognosis.
