Therapeutic challenges include large sessile polyps with diameters of more than 2cm and heights of more than 2.5 mm and flat polyps less than 2.5 mm high 6. These types frequently exhibit high-grade dysplasia, malignancies, adenocarcinoma 2, 3 and high rates of complications. Complications which can occur during resection include hemorrhaging and perforations while postpolypectomy syndrome occurs afterwards 4.
Los retos terapéuticos exigentes son los pólipos grandes > 2 cm sésiles altura mayor a 2,5 mm y planos altura menor a 2,5 mm 6, ya que estos presentan más frecuentemente displasia de alto grado, pólipo maligno o adenocarcinoma 2, 3 y además mayor tasa de complicaciones durante o después de la resección, tales como hemorragia, perforación y síndrome postpolipectomía 4.
