?leak port replacement surgery on 8/28

I WAS WONDERING IF THIS SOUNDS RIGHT---- I HAVE BEEN LOSING FLUID OUT OF MY BAND VERY SLOWLY SINCE DECEMBER ..MY DOCTOR SAID HE THINKS THAT MY PORT IS LEAKING A VERY SLOW LEAK THAT WOULD NOT SHOW UP UNDER FLUORO ( I AM AN X-RAY TECH) WHICH IS RIGHT. I NOW NEED PORT REPLACEMENT SURGERY ON 8/28. MY DOC SAID THAT HE WILL INJECT METHALINE BLUE INTO MY PORT TO CHECK WHERE THE LEAK IS IF HE DOES NOT SEE IT HE WILL STILL REPLACE THE PORT. WAIT A MONTH GIVE ME A FILL WAIT ANOTHER MONTH TO SEE IF IT IS STILL LEAKING IF SO THEN IT IS THE BAND ITSELF AND ANOTHER SURGERY IS REQUIRED. HE SAID THAT HE NEEDS TO DO IT THIS WAY BECAUSE OF INSURANCE REASONS. ALSO IF I DO HAVE TO GO IN FOR BAND REPLACEMENT THEN I CAN DECIDE IF I WANT BYPASS SURGERY INSTEAD. ANY OPINIONS......:confused2:
