Bowel rupture, anus rupture.
Anal tearing of the mucosa with consequent painful defecation.
Age peak: middle adulthood.
Mostly occurring at 6 o'clock in lithotomy position, poorly healing cleft-shaped fissure/rhagade extending from the linea dentata to the outer skin. The internal sphincter may also be affected. There may be severe, cramping pain during defecation. It is not uncommon for patients to have a marked fear of defecation due to this dolor. Consequently, spasms of the sphincter muscle may occur.
Anal, rear commissure is typical (lithotomy position 6 o'clock).
The aim is to remove the excessive sphincter tone
