Efficacy and safety of balloon-occluded retrograde transvenous obliteration for gastric fundal varices in children

Gastrointestinal Bleeding in Children: Current Management, Controversies, and Advances

Upper gastrointestinal bleeding (UGIB) in children has many causes, with its prevalence varying by age. Often presenting as hematemesis or melena, the initial treatment is stabilization of the patient, including protection of the airway, fluid resuscitation, and a transfusion hemoglobin threshold of 7 g/L. Endoscopy should be performed with the goal of using combinations of therapies to treat a bleeding lesion, generally involving epinephrine injection along with either cautery, hemoclips, or hemospray. This review discusses the diagnosis and treatment of variceal and non-variceal gastrointestinal bleeding in children with a focus on current advances in the treatment of severe UGIB.

Cirrhosis and Portal Hypertension in the Pediatric Population

Cirrhosis is a complex process in which the architecture of the liver is replaced by structurally abnormal nodules due to cirrhosis. Cirrhosis frequently leads to the development of portal hypertension. In children, portal hypertension may be caused by a wide range of etiologies, including extrahepatic portal vein obstruction, biliary atresia, alpha 1 antitrypsin deficiency, and autoimmune hepatitis. Gastroesophageal varices and ascites are two of the complications of portal hypertension likely to cause morbidity and mortality. This review also discusses extrahepatic manifestations of portal hypertension and treatment options.

Balloon-occluded retrograde transvenous obliteration for recurrent fundal gastric variceal bleeding in an adolescent

Gastric variceal bleeding is associated with high morbidity and mortality. Balloon-occluded retrograde transvenous obliteration is a relatively new treatment used to control bleeding gastric varices that involves transvenous sclerosis of gastric varices through a spontaneous gastrorenal shunt. Here, we report on a 14-yr-old patient that underwent balloon-occluded retrograde transvenous obliteration for refractory bleeding fundal varices in the setting of esophageal varices and cirrhosis, which did not respond to medical management or endoscopic injection. This case report serves as a reminder that balloon-occluded retrograde transvenous obliteration can successfully control fundal variceal bleeding in pediatric patients and may serve as a bridge to liver transplantation.
