My 2 year old for the last 10 months or so he s had issues with projectile vomiting averaging 5 x a month; they put him prevacid and it seemed to have worked for a month and a half but it started again. Well, he just had an endoscopy done and all looked well inside BUT anatomically it sounds a little challenging, he seems to have a short esophagus the has a curvature towards the end.. What would the outcome be in a case like this? Is this a rare form? Would it be expected to straightened out on it s own as he grows?
