Esophageal Cancer - colon cancer - now maybe peritoneal carcinomatosis

I don't know if anyone else has experienced this but I am at wits end! This is long and I apoligize but I hope someone responds.
My husband (53 years old) had his entire esophagus removed 2 1/2 years ago - as well 30 lymph nodes - a couple of the lymph nodes did have cancer also. He had chemo and radiation for about 6 months. He was okay until April 23 when he started throwing up everything and had pain in his stomach (he had not been feeling really himself for quite some time - he had gone back to work and was so exhausted when he got home) I took him to the same hospital (ER) where his previous surgery was done. They said he had a blockage in his small intestine. Of course my first thought was is it a tumor? They said it was probably scar tissue - they wanted to treat it non-surgically first - they said that was the procedure. They didn't want to do surgery if they didn't have to since it might cause more scar tissue. After 4 weeks of no apparent change in my husband they decided to operate - again after the surgery I asked was there a tumor - the answer was no. A few days later I got a call that I was to come to the hospital for a family meeting - well I knew what that meant. We were told the piece they removed from his colon was a cancerous tumor - the same cancer cells that was in his esophagus. SHOCK!! They sent him home the next day. By the way, they didn't give him any nutrients the first couple of weeks he was in the hospital - he was losing so much weight - they finally inserted a pic line after I called his primary care doctor to say how bad my husband looked.
So a couple of weeks ago my husband had a pet scan to see if the cancer had spread elsewhere - my hunch was yes - where had this cancer been for the past 2 years??
The pet scan shows something but they are not sure - it may be peritoneal carcinomatosis. I asked his onc how do we find out if it is cancer - he said well we wouldn't want to do surgery - it would cause scar tissue - I thought I WOULD SCREAM! Let's see - operate and find out if he has peritoneal carcinomatosis or give him the chance of getting scar tissue. I think I would settle for the scar tissue. So now what I have found out about peritoneal carcinomatosis is that it can be caused when surgery is done on the colon and there is cancer in the colon - when the colon is cut the cancer seeds into the abdominal cavity. Not sure if there is a way for a surgeon to prevent that from happening. Chemo is not effective for this type of cancer because it can not reach this cancer. My husband is in pain everyday, not gaining weight - some days he can barely move. The onc was baffled and told my husband to come back in 2 weeks that he wanted to talk to some other docs and the radiologist - don't you think he should have done that before my husband's appointment?? So the onc called me friday and said now he wants to see my husband sooner - guess after talking it over he realized how serious this can be. I think we need to be told all the facts no matter how bad - my husband is in denial, which I can't blame him. We have decided to get a second opinion after meeting with his onc on thursday. Has anyone had this type of cancer after having Esophageal Cancer??
