Sorry that one is truly beyond me I am not good with blood and insides and things My advice to anyone and everyone writing Wikipedia is to stick to a subject you undertstand In an effort of collaboration I did try to read it through but when I came to this picture File Esophageal varices wale jpg I felt a little unwell myself However it is clearly very well written and informative and I think it is fantastic that someone with such a grasp of the subject takes the time to write at Wikipedia one page like that is worth a billions of some of the others Congratulations and good luck I m sure it is FA standard already
