Gastrointestinal bleeding in children.
We prospectively evaluated 139 consecutive children presenting to the Sanjay Gandhi Postgraduate Institute of Medical Sciences (Lucknow, India) with gastrointestinal (GI) bleeding from January 1991 to November 1994. Our aims were to find out whether the causes of GI bleeding in a developing country differed from developed countries and how the application of newer diagnostic techniques would help in the diagnosis of GI bleeding. Barium studies, endoscopy, technetium-99m-labelled (erythrocytes and pertechnetate) scans, selective abdominal angiography using a digital subtraction technique and rectal endoscopic ultrasonography were performed. Upper GI bleeding (n = 75) was variceal in 71 (95%) children (extrahepatic portal venous obstruction in 65, cirrhosis in six) and non-variceal in four (5%) cases (Henoch-Schonlein purpura, idiopathic thrombocytopenic purpura, drug-induced gastric erosions and pseudoaneurysm of the gastroduodenal artery due to idiopathic chronic calcific pancreatitis). Causes of lower GI bleeding (n = 64) were colitis (27 cases; 42%), colorectal polyps (26 cases; 41%), enteric fever (n = 3), solitary rectal ulcer (n = 3), portal hypertensive colopathy (n = 2), colonic arteriovenous malformation (n = 1) and internal haemorrhoids (n = 1). One patient remained undiagnosed. Angiography performed in four children was diagnostic in two. In one child with massive lower GI bleeding from portal colopathy, the bleeding site (caecum) was localized by intra-operative colonoscopy, while in the other child with portal colopathy, rectal endoscopic ultrasonography was performed to substantiate the diagnosis. We conclude that the causes of upper GI bleeding in children in developing countries are different from those in developed countries (variceal bleeding due to extrahepatic portal venous obstruction is the most common cause, while peptic ulcer is rare). However, the spectrum of lower GI bleeding is similar to that of developed countries. Application of newer diagnostic techniques is helpful and safe in the identification of the cause of GI bleeding in children.
