Frequent Vomiting, Appendix Removed, Blood Filled Vomit. Treatment ?
Thanks for posting your query. I can understand your concern for these symptoms because brown colored vomitus indicates blood in the vomiting and is called hematemesis. The farther the source of blood from the mouth, the darker the blood will be. One of the reasons can be ulcer. In children, the most common causes are gastric and duodenal ulcers, esophagitis, gastritis, and varices.
Since your son is having a history of chronic vomitings, hence XXXXXXX weiss tear (a tear in the mucosa layer of oesophagus) is an important possibility in your son’s case. Mallory-Weiss tears are most often caused by repeated vomiting, retching, or a vigorous bout of coughing.
Esophageal varices result can from portal hypertension, regardless of the age group. The increased resistance to blood flow through the portal system can be due to prehepatic, intrahepatic, and suprahepatic obstruction, but the most common causes of portal hypertension in children include portal vein thrombosis (prehepatic) and biliary atresia (intrahepatic).
I suggest you an immediate evaluation from a gastroenterologist as your son need upper GI endoscopy to rule out all these causes and a CT scan liver and biliary tree.
