My daughter was operated for bilary Atresia in the first few months post her birth. Everything was fine except when she turned 1.7 years she got retrophrangeal Abscess due to which she got abscess removed through her neck. While she was recovering and on the day if leaving hospital she vomited blood twice in 5 hours. She again went for the surgery through chest for abscess to be removed. Now she has turned 1.10 years and her belly is big. We have a date for endoscopy coming next month. Is it natural or is it alarming or is it ..
