A close friend is going to have a sigmoidectomy soon Am concerned about her post-op care after she s released from hospital ( U of Penn). Family members, sister and daughter, are coming to stay with her, but I m uncomfortable with their lack of knowledge. My father was a head and neck surgeon, I ve worked in hospitals, etc., but am concerned, since I don t know much about abdominal surgery, - effect on abdominal muscles, healing time.. can t think of all the questions I may have.
