My Dad is on cycle 4 of his chemo treatment. He was diagnosed in Sept and surgery was not an option. He had the j-tube inserted and it was a tough road at the beginning. Although things have settled a bit he is currently on his 3rd tube and may be getting another new one inserted after 5 weeks of the last one. It continues to crimp and the opening of the tube is now very loose. Most people I've spoken to have not had so many issues with the j-tube? Any personal experience to share with us??
