Leaking Feeding Tube

My husband had a j-tube placed before chemo. I don’t think it had enough time to heal as directly after cycle one of FLOT it got infected and started leaking uncontrollably. He was put on antibiotics and given white blood cell boosting injections because his count crashed to almost nothing. The surgeon denied the tube was infected, inflated the balloon a bit more, and basically said it’s just part of the hassle of going through cancer treatments. He said removing it isn’t an option because it probably won’t heal. My husband is beyond frustrated and we are afraid this is going to keep happening and possibly compromise his chances at getting through this to recovery. He’s been taking care of the tube as instructed and it was starting to look better, but now it’s once again hurting him and the fluid inside is turning green. I’m beginning to wonder if these people are on their game, honestly. Has anyone else has this problem? Also, do white blood cell crashes usually necessitate injections? I felt like he needed them (his counts were crashed as of a couple of days ago and round 2 is supposed to begin on Wednesday) regardless of the tube issues. He almost ended up in the hospital one night because his temperature spiked very high, but then it went back down again.
