Hello! my mother have an anal fissure she has did an operation befor 19 years old and now the same problem repeat with a cicatrization in the buttock ?

Colorectal surgeon: Anal fissures are tricky business. They are very painful with each bowel movement, and there is usually some associated bleeding. There have definitely been some surgical and non-surgical management developments over the past 2 decades, so your mother should seek the opinion of a qualified colorectal surgeon or general surgeon who has an interest in this problem. Good luck.
