7 weeks post nissen. day time reflux cured, but am having nighttime reflux. i swallow and hear a squeak that sounds liquidy, not nearly as bad as pre-op. to verify wrap is good: barium? motility test? or two soon to tell if gerd is back?

Different questions: A barium swallow test (or a gastrograffin swallow test) is usually the best test to check to see if a Nissen fundoplication ("wrap") is succesful. The GERD should be lessened or gone at this point (usually within 1-2 weeks of fundoplication if done correctly) but I suppose another trial of medications could be in order. Failing that, other causes need to be investigated by a GI doc. TTYD, and GL!
