Healing after hemorrhoidectomy

Abstract

Conclusions Extensive intra-anal wounds are produced after all forms of hemorrhoidectomy investigated unless mucous membrane is preserved by submucosal dissection. Regeneration of mucosa proceeds rapidly above the pectinate line. Delayed healing is observed only in the skin-lined part of the anal canal. Preservation of mucous membrane at operation may predispose to later recurrence. Extensive, superficial destruction in the anal canal is only rarely followed by significant stenosis and may actually serve as a guard against later recurrence.
