Hi, Thanks for writing in to us. Adhesions in intestines are a difficult problem to treat fully. As you have mentioned, your sister has had a second surgery for the same reason. In this scenario, adhesions appearing again is the first suspicion. Not all adhesions can be seen on ultrasound and CT scan. Right now she must first get an abdominal erect X ray done to see for any significant sub acute or acute obstruction. Following this the surgeon may put her on medication or may decide to operate again if there is indication of the intestines getting blocked. She should not ignore the pains any longer and seek surgeon consultation at the earliest. Hope this helps
