Peritoneal adhesions

Peritoneal adhesions form when the peritoneum — the thin lining covering the abdominal and pelvic organs — heals abnormally after inflammation, infection, or surgery, causing organs or tissue surfaces to stick together. In the pelvis, this overlaps closely with pelvic adhesions and can involve the tubes, ovaries, uterus and bowel. Common causes relevant to fertility include pelvic infection, endometriosis, appendicitis or peritonitis, and previous abdominal or pelvic surgery. Extensive peritoneal adhesions can make future surgery more difficult and are one reason IVF is sometimes preferred over repeat pelvic surgery.
