Abstract
OBJECTIVE: To estimate the risk of bleeding during adolescence and early adulthood in a group of children with portal vein obstruction who had not undergone an effective treatment beforehand. STUDY DESIGN: Children (n = 44) were followed up from age 12 years to a mean age of 20 years (range, 15-34 years). Actuarial risk of bleeding, related to previous occurrence of gastrointestinal bleeding and to pattern of varices at age 12, was calculated yearly. RESULTS: Twenty-four children presented with gastrointestinal bleeding after age 12, and 20 did not bleed. The overall actuarial probability of bleeding was 49% at age 16 and 76% at age 24. Probability of bleeding at age 23 was higher in children who had bled before age 12 than in children who had not bled (93% vs 56%; P =.007). Probabilities of bleeding at age 18 and at age 23 were 60% and 85%, respectively, in patients who had grade II or III esophageal varices at age 12. The 9 children without varices or with grade I varices only on endoscopy did not bleed between the ages of 12 and 20 years. CONCLUSIONS: Children with portal vein obstruction have a >50% risk of bleeding during adolescence; the pattern of varices on endoscopy at age 12 may have a prognostic value.
