What is the definition or description of: adhesions?

Scar tissue: Adhesions are scar tissue which can form after any abdominal surgery. The severity depends on whether infection/inflammation was present at the time of surgery. Adhesions are like bands or spider webs that form around the abdominal organs/intestines. Sometimes adhesions are light and cause no problems, sometimes tremendous problems, like crazy glue in the abdomen. Can cause pain or blockage.
