[Outpatient treatments of haemorrhoidal disease].

Only three non-surgical treatments of haemorrhoids are clearly validated: infrared coagulation, injection sclerotherapy and rubber band ligation. Those procedures are only indicated for painless symptoms related to internal haemorrhoids, i.e. bleeding at defecation or spontaneously reducible prolapse. Their main interest is to be possible on the outpatient clinic, with a simple anuscope, without enema or anaesthesia, since they are applied to non-sensitive area on the top of internal haemorrhoids. The aim of all these treatments is to create local fibrosis, which reduces vascular tissue and hold rectal mucosa to underlying muscle. Short-dated efficiency of all techniques is similar on bleeding. After one and three years, rubber band ligation is clearly more efficient than other techniques, especially on prolapse. Secondary effects are non-constant and usually minor, as transient pain or tenesmus, and mild bleeding for few days. Infrequent complications may occur, only after haemorrhoidal banding and sclerotherapy, as thrombosis, massive delayed bleeding or local abscess. Exceptional life-threatening pelvic cellulitis cases have been reported.
