The most serious error when performing hemorrhoidectomy is failure to leave adequate bridges of mucosa and anoderm between each site of hemorrhoid excision. If a minimum of 1.0–1.5 cm of viable anoderm is left intact between each site of hemorrhoid resection, the risk of developing anal stenosis is minimized. Preserving viable anoderm is much more important than is removal of all external hemorrhoids and redundant skin.
