Adhesions are lumps of scar tissue that form inside your body. Previous surgeries cause about 90 percent of abdominal adhesions. They can also develop from trauma, infections, or conditions that cause inflammation. Adhesions can also form on the organs and cause organs to stick together. Many people with adhesions don’t experience any symptoms, but some people may have discomfort or digestive problems. Abdominal adhesiolysis is a type of surgery that removes these adhesions from your abdomen.
