When this occurs the child may vomit blood that can be either bright red or even dark-looking flecks of blood that are often described as “coffee grounds”. Sometimes, upper GI bleeding can cause black, sticky stools (melena). How common is upper GI bleeding? Pediatricians and pediatric gastroenterologists see this problem quite regularly. It is estimated that GI bleeding accounts for 1% of all pediatric hospitalizations. Why does bleeding happen? Stomach acid can irritate the lining of the esophagus to the point of causing bleeding. In other cases, retching or repeated vomiting can cause a tear in the lining of the lower esophagus (a Mallory- Weiss tear). Sometimes liver problems can cause blood vessels in the esophagus or stomach to be enlarged, and these blood vessels may be more likely to bleed. Certain medications such as non-steroidal anti-inflammatory drugs (ibuprofen, aspirin) can cause irritation or ulcers that bleed. Infections, particularly Helicobacter pylori, can result in bleeding ulcers. Uncommon causes of upper GI bleeding are polyps and abnormal blood vessels. How is upper GI bleeding treated? Upper endoscopy is the best way to determine the cause of the upper GI bleeding and will be recommended if the bleeding has been serious. In this test, a flexible tube with a tiny video camera is used to look directly at the upper GI tract. If active bleeding is seen, it can be stopped by numerous methods including injection of medicines, heating/ burning the abnormal site, or placing metal clips to close any bleeding blood vessels. More commonly, upper GI bleeding is treated with medications that decrease the stomach’s acid, allow- ing the lining of the upper GI tract to heal. What can we expect? Most children with upper GI bleeding recover very well. Those with special liver or blood clotting problems may have m
