Haemorrhoids have, in literature, extremely high ranges of prevalence, 4,4% to 36% and there is a debate on the best treatment for III degree hemorrhoids. The Stapled Hemorrhoidopexy is indicated in grade III haemorrhoids due to its advantages vs. other techniques in pain reduction and time before resume of normal activity. The new technique of Doppler guided trans-anal arterial ligation (THD) appear to be another important therapeutic tool thanks to its scarce complications, the minimally invasive procedure and efficacy of the short term results. The rationale of the two surgical techniques is different: in fact, the Stapled Hemorrhoidopexy is based on the hypothesis that the mucosal and sub/mucosal resection and stapling can cure the prolapse, etiologic factor of haemorrhoids; on the other hand, the interruption of the arterial inflow of hemorrhoids by THD reduces hemorrhoidal tissue." Aim of this study is to compare 2 techniques: The doppler guided transanal haemorrhoidal dearterialisation with the THD device and the stapled Haemorrhoidopexy (according to Longo) for III degree (Goligher) haemorrhoid, not regarding the number of prolapsed piles
