Hi - I too have never heard of any contraindications with cisplatin and a peg... In fact just the opposite... I had no problem with it going in and or coming out.. And no leakage. Or any other issue though I would like to say I couldn't use it because the formulas didn't agree with me. Most drs push for a peg - very surprised to hear your drs. claim. a peg can be priceless. The only negative I've found with them is that if you don't continue to swallow it can lead to swallowing difficulties after treatment is over.
