title: Semi-open hemorrhoidectomy.
abstract: The concept that hemorrhoidal disease is a consequence of disorders of the cephalic portion of the anal canal, i.e. weakness of the vascular cushions and the connective tissue, is the basis for modifying the usual surgical technique in many aspects. The two main differences of the method described are: (i) the internal plexus is treated by parceled ligature, avoiding resection of the mucosa, but providing a firm fixation of the submucosa and subsequent fixation of the anal epithelium to the underlying sphincter in the anal canal; (ii) the external plexus is removed preserving as much as possible the anal margin skin, and the resulting wound is partially closed, resulting in a small drainage area; and (iii) a firm fixation of the submucosa and subsequent fixation of the anal epithelium to the underlying sphincter are achieved without mucosa resection.
