A new concept of the anatomy of the anal sphincter mechanism and the physiology of defecation. Treatment of hemorrhoids: report of a technique.
A technique for the treatment of hemorrhoids has been presented. It is based on a recent study in which the persistence of the anorectal band, a remnant of the anorectal sinus, and failure of rectal neck remodeling are considered responsible for the initiation of the hemorrhoid disease. The constricting effect of the anorectal band on the rectal neck results in elevation of its pressure, straining at defecation, and prolapse of the rectal mucosa. There were 502 patients with third and fourth degree hemorrhoids. The preoperative rectal neck pressure was high in all of them. The technique comprises division of the anorectal band and hemorrhoid ligation. The results were satisfactory, and the complications were negligible. The rectal neck pressure was normalized and straining disappeared. The procedure is simple and easy. Compared with the other techniques for hemorrhoid treatment, it offers the advantage of dealing with the primary etiologic factor.
