Diagnostic and therapeutic approach to upper gastrointestinal bleeding

ABSTRACT

Background: There is a lack of clarity about the approach to and management of upper gastrointestinal (UGI) bleeding in children.

Aim: To examine the recent literature on UGI bleeding in children in order to outline the diagnostic approach and management.

Methods: The English language literature was searched for articles on UGI bleeding in children. Special attention was paid to its prevalence, risk factors, clinical approach and management.

Results: Although UGI bleeding is a common complication (10%) in paediatric intensive care units (PICU), clinically significant UGI bleeding (haemodynamic instability, fall in haemoglobin by 2 g/dL and/or a requirement for blood transfusion) is less common (1.6%). In low- and middle-income countries, clinically significant UGI bleeding is commonly owing to variceal bleeding whereas non-variceal aetiologies (e.g. peptic ulcer disease) are common in high-income countries. The fundamental clinical principles of managing UGI bleeding are immediate assessment of severity, detecting possible causes and stabilising the haemodynamic status. In suspected cases of variceal bleeding, intravenous octreotide and, in non-variceal bleeding, administration of a proton pump inhibitor (PPI) should be commenced immediately. UGI endoscopy plays a vital role in diagnosis and management. Over-transfusion should be avoided (target haemoglobin 7–9 g/dL). Stress ulcer prophylaxis is recommended in a select group of patients in PICUs (e.g. respiratory failure, coagulopathy and paediatric risk of mortality score ≥10).

Conclusions: In clinically significant UGI bleeding, the primary goal is to restore the haemodynamic status, followed by early endoscopy. Intravenous octreotide in suspected variceal and PPI in non-variceal bleeding should be administered early. Stress ulcer prophylaxis should be restricted to high-risk children only.
