A new entry into the arena of excisional hemorrhoidectomy is the circular stapled hemorrhoidectomy .The technique uses a circular, transanally placed pursestring suture 4 cm from the dentate line and within the enlarged internal hemorrhoids. A 31-mm stapler is then placed transanally to perform a circumferential excision of the hemorrhoidal tissue and a repositioning and fixation of the anoderm to its proper location in the anal canal. The results appear promising, with decreased postoperative pain, shorter periods of convalescence, and similar complication rates compared with other forms of excisional hemorrhoidectomy.
