My husband had stage iv colon cancer where chemo, surgery & radiation were required to remove tumor. A couple yrs after that (actually in January 2015) he had a small intestinal resection because of the radiation, surgeries etc that developers td adhesions. They also had to cut thru mesh that had been placed during a hernia repair. It is now only 4 months later & he's got another blockage. Are there any options in order to avoid another surgery that are available. He's losing weight & very discouraged at this date. Thank you. Dolores
