Underwater Piecemeal Endoscopic Mucosal Resection (EMR) With Hot Snare of a Giant Sigmoid Polyp

We present an 84-year-old male where a CT scan was performed for constipation study. The CT-scan showed a giant lobulated sigmoid lesion and an appendicular adenocarcinoma.In the colonoscopy we saw a giant sigmoid polyp that obstructed the intestinal lumen and was located between two angulations, but there were no endoscopic signs of deep invasion. We performed a piecemeal underwater EMR with hot snare to avoid a subtotal colectomy. The anatomopathological study showed a tubulo-villous adenoma with high and low-grade dysplasia with foci of intramucosal adenocarcinoma (pTis).Given the patient’s comorbidities it was decided to do only endoscopic follow-up
