We aim to identify factors associated with invalid TE results in a tertiary referral center in a large prospective cohort study. Methods: Consecutive learn more patients who were referred for TE between September 2011 to March 2013 were included. Age, gender, body mass index (BMI) and waist circumference were recorded. An invalid result was defined as failure to capture 10 readings or interquartile range (IQR) of more than 30%. Patients were assessed with Fibroscan™
using a medium-sized (M) probe. Results: Among the 1919 cases referred, valid results were acquired in 1851 (96.5%). Univariate analysis showed that high waist circumference (p = 0.003) and high BMI (p = 0.001) were associated with invalid results. Advanced age and female gender were not statistically significant. In multivariate analysis which included age, gender, BMI, and waist circumference, BMI was shown to be the only independent predictor for invalid results (Table 1). The number of invalid TE studies increased with increasing BMI (5.2% in BMI > 25 vs 11.5% in BMI > 30 vs 26.1% in BMI > 35). Conclusion: Body mass index is independently associated with invalid results for transient elastography. Patients
with BMI > 35 should consider other modalities to assess liver fibrosis.

Duodenal varices (DV) although an uncommon cause, are an important cause because of the severe nature of the bleed
and associated adverse outcome. Methods: We retrospectively evaluated patients with DV seen at our institution over past 4 years. Their clinical, endoscopic and endoscopic ultrasound (EUS) features were analysed as was the treatment and its outcome. Results: Ten patients (9 males; mean age was 35.8 ± 7.68 years) with DV were studied. Five patients had underlying cirrhosis and five had DV see more because of non-cirrhotic portal hypertension (four patients had extrahepatic portal venous obstruction and one patient had non-cirrhotic portal fibrosis). Five patients presented with upper gastrointestinal bleed (GI) whereas in the remaining five patients DV were detected on endoscopy performed for evaluation of portal hypertension. Endoscopy revealed submucosal lesion in 9 patients whereas in one patient an initial endoscopic diagnosis of dieulafoy’s lesion was made. But EUS could clearly identify DV in all the patients.
