Endoscopic ultrasonography - emerging applications in hepatology

Table 3 Role of endoscopic ultrasonography in the evaluation of the outcome of endoscopic therapeutics for esophageal varices

Ref.	Study design	Endoscopic findings	EUS findings
Masalaite et al[35]	Prospective The role of EUS in predicting the recurrence/rebleeding of esophageal varices: EBL (n = 40)	Recurrence of esophageal varices: 19 (47.5%) within 12 mo of EBL	EUS independent prognostic factors for variceal recurrence: Severe esophageal collaterals (OR= 24.39) multiple esophageal collaterals (OR = 24.39)
Lo et al[39]	Prospective The role of EUS in predicting the recurrence of esophageal varices: ES (n = 35) vs EBL (n = 44)	Recurrence of esophageal varices: 43% ES vs 70% EBL	Paraesophageal varices: 51% ES vs 86% EBL
de Paulo et al[40]	Prospective The role of EUS-guided ES: ES (n = 25) vs EUS-guided ES (n = 25) of esophageal collateral vessels	Mean number of sessions until eradication: 4.3 ES group vs 4.1 for the EUS-ES Recurrence of esophageal varices: 16.7% ES vs 8.3% EUS-ES	Esophageal collaterals at the end of the sclerotherapy program: 8 patients in ES vs 0 patients in EUS-ES

EUS: Endoscopic ultrasonography; EBL: Endoscopic band ligation; ES: Endoscopic sclerotherapy.
