Computed tomography indices and criteria for the prediction of esophageal variceal bleeding in survivors of biliary atresia awaiting liver transplantation

Background/Objective: About 20% of biliary atresia (BA) survivors have attacks of esophageal variceal bleeding. We propose a method to evaluate the risk of esophageal variceal bleeding (EVB) using noninvasive indices by multislice computed tomography (CT). Methods: We reviewed 31 potential living-re...

description Background/Objective: About 20% of biliary atresia (BA) survivors have attacks of esophageal variceal bleeding. We propose a method to evaluate the risk of esophageal variceal bleeding (EVB) using noninvasive indices by multislice computed tomography (CT). Methods: We reviewed 31 potential living-related liver recipients aged 99–5314 days (mean, 1474 days) who underwent CT examinations using a 64-slice multislice CT scanner. Of the 31 patients, 19 patients (Group A) with fecal occult blood had EVB on esophagogastroduodenoscopy; the rest belonged to Group B. Splenic diameters (mm) were divided by body heights (m) and platelet counts (1000/mm3) to produce standardized ratios of transverse splenic length/body height/platelet count (SLHPR). The transverse diameters of paraesophageal veins (PVs) and perigastric veins (PGVs) were measured adjacent to the lower thoracic esophagus and within the lesser sac, respectively. Results: According to a receiver operating characteristic curve analysis, the SLHPRs (r=0.833), transverse PV (r=0.957), and PGV (r=0.987) diameters were better predictors of EVB than demographic and laboratory variables. However, the transverse diameters of PGVs and PVs were the most accurate predictors of the EVB. Conclusion: For candidates awaiting liver transplantation, screening by noninvasive SLHPR and the transverse diameters of PGVs and PVs by CT may help to identify BA patients with a high risk of EVB.
