Endoscopic variceal sclerotherapy (EVS) has been considered the mainstay of therapy for bleeding esophageal varices in adults. However, recent data have shown that endoscopic variceal ligation (EVL) is just as efficacious and has fewer complications than EVS. Although there are many reports concerning EVL in adults, only a few studies have been done in children. This report describes experience with EVL in 22 children with esophageal variceal hemorrhage. Eighty-seven EVL procedures were performed during a 9-year period in 22 children. The causes of portal hypertension were biliary atresia (10), portal vein thrombosis (8), chronic active hepatitis (1), cirrhosis secondary to cystic fibrosis (2), and primary sclerosing cholangitis (1). The age range at the onset of variceal bleeding was 8 months to 19 years. Twelve patients had EVS before EVL treatment was begun. Distal esophageal varices (one to four per session) were mechanically ligated using an elastic band ligature device attached to a flexible endoscope. The aim of therapy was obliteration of distal esophageal varices by EVL, every 2 to 4 weeks, until eradication. Subsequent EVL was dictated by the status of the varices. Outcome was assessed with respect to survival, rebleeding, status of varices, and complications. The patients underwent a mean of four sessions of EVL (range, one to eight). Four patients subsequently underwent liver transplantation. Of the 18 patients remaining (average follow-up period, 5.3 years), 12 had their varices eradicated (average of four EVL sessions), four are still in treatment, one has not been evaluated in the past 4 years, and one died of liver failure. Complications included bleeding between sessions (6 patients), cervical esophageal perforation (1 patient), and transient fever (2 patients). No child has experienced symptoms of esophageal stenosis or gastroesophageal reflux. Two patients died of liver disease, unrelated to bleeding from portal hypertension. EVL is effective in controlling variceal hemorrhage in children with portal hypertension, regardless of etiology. The complication rate is low, and EVL is an acceptable and perhaps preferable alternative to EVS in children with esophageal varices.

The clinical histories of 46 adult patients (24 men and 22 women, mean age 20.6 +/- 5.1 years) diagnosed of cystic fibrosis were reviewed evaluating the digestive alterations. The age at diagnosis of cystic fibrosis was 5.63 +/- 5.3 years (range: newborns-19 years). The initial diagnosis was established by ileus meconium, in four, lung disease in 15, steatorrhea in 12, lung disease and steatorrhea in 13 and following the diagnosis of cystic fibrosis in siblings in two. Four patients presented ileus meconium, nine occlusive syndrome of the distal intestine, 42 steatorrhea (20 severe, 12 moderate and 10 mild), with the severity of the steatorrhea not being associated with the severity of the respiratory insufficiency. Two patients presents rectal prolapse, five gastroesophageal reflux syndrome (four with hiatal hernia), six cholelithiasis, one recurrent pancreatitis without detection of biliary lithiasis, one neonatal cholestasis and 10 malnutrition (five severe and five moderate) fundamentally in relation to the severity of the lung disease and, to a lesser degree, liver disease. In 10 patients chronic liver disease was diagnosed corresponding to established cirrhosis in seven, indicating liver transplantation in two. In most cases, the liver disease was already manifest in adolescence even in the cirrhotic stage. Cholangiography by magnetic resonance was useful in the study of liver disease showing abnormalities which imitated primary sclerosing cholangitis. Treatment with ursodesoxicholic acid at a dosis of 20 mg/kg/day led to a significant decrease in the transaminase values and overall of gammaglutamyltranspeptidase but did not avoid complications in the cirrhotic stages. Genetic studies performed in 36 patients detected the delta F508 mutation in 69.4%, being found in almost all of the patients with ileus meconium, occlusive syndrome of the distal intestine, liver disease, cholelithiasis and malnutrition.

Helicobacter Pylori (HP) persistently colonizes the stomach in about 50% of the globe population and it is the main risk factor for peptic ulcer, as well as for gastric adenocarcinoma and MALT gastric lymphoma. The treatment for HP revolutionized the management of the peptic ulcer disease, providing permanent healing in many cases. Preventing colonization of HP would be the primary prevention of gastric malignancy and peptic ulceration. At the same time, the presence of HP provides protection for some diseases (gastroesophageal reflux disease and its complications, esophageal adenocarcinoma, asthma), the eradication of the microorganism having negative repercussions. HP has an increasingly recognized role in other extragastric pathologies. Thus, immune thrombocytopenic purpura has improved after treating HP infection. There are controversial association with ischemic heart disease and cerebrovascular disease. The current article highlights an important association between HP infection and a range of hepatobiliary disorders such as biliary lithiasis (where even an etiological role is involved), cholestatic syndromes (primary sclerosing cholangitis and primary biliary cholangitis), chronic hepatitis B virus, chronic hepatitis C virus, with an evolution towards cirrhosis and hepatocellular carcinoma.
