Although the treatment options for angiodysplasias are numerous, including segmental bowel resection and selective mesenteric embolization, endoscopic coagulation of angiodysplasias is becoming a treatment of choice using either heated probe or lasers, such as Nd:YAG (neodymium-doped yttrium aluminium garnet) and argon. Argon laser treatment is recommended for mucosal or superficial lesions, because the energy penetrates only 1 mm. Nd:YAG lasers are more useful for deeper lesions, because they penetrate 3-4 mm.
