Core tip: The objective of this review is to critically analyze the available data and our experience with this disease, with suggestions for daily practice and further research. In our view, laser treatment is an obsolete technology and can be abandoned. The bipolar probe (BiCAP) is very well indicated for patients with implantable electronic devices. The best way to use formalin is still unknown. More studies with band ligation, cryotherapy and radiofrequency ablation are still needed. Argon plasma coagulation has emerged as the front-runner, due to its ease of use, affordability, better-defined settings, effectiveness and low risk of complications.
