Background: Gastric varices (GVs) are conventionally managed with endoscopic cyanoacrylate (E-CYA) glue injection. Endoscopic ultrasound (EUS)-guided therapy using combination of coils and CYA glue (EUS-CG) is a relatively recent modality. There is limited data comparing the two techniques. Methodology: This international multicentre study included patients with GV undergoing endotherapy from two Indian and two Italian tertiary care centres. Patients undergoing EUS-CG were compared with propensity-matched E-CYA cases from a cohort of 218 patients. Procedural details such as amount of glue, number of coils used, number of sessions required for obliteration, bleeding after index procedure rates and need for re-intervention were noted. Results: Of 276 patients, 58 (male 42, 72.4%; mean age-44.3 ± 12.1 years) underwent EUS-CG and were compared with 118 propensity-matched cases of E-CYA. In the EUS-CG arm, complete obliteration at 4 weeks was noted in 54 (93.1%) cases. Compared to the E-CYA cohort, EUS-CG arm showed significantly lower number of session (1.0 vs. 1.5; p < 0.0001) requirement, lower subsequent-bleeding episodes (13.8% vs. 39.1%; p < 0.0001) and lower re-intervention (12.1% vs. 50.4%; p < 0.001) rates. On multivariable regression analysis, size of the varix (aOR-1.17; CI 1.08-1.26) and technique of therapy (aOR-14.71; CI 4.32-50.0) were significant predictors of re-bleeding. A maximum GV size >17.5 mm had a 69% predictive accuracy for need for re-intervention. Conclusion: Endoscopic ultrasound-guided therapy of GV using coil and CYA glue is a safe technique with better efficacy and lower re-bleeding rates on follow-up compared to the conventional endoscopic CYA therapy.

Abstract
Background: Gastric varices (GVs) are conventionally managed with endoscopic cyanoacrylate (E-CYA) glue injection. Endoscopic ultrasound (EUS)-guided therapy using combination of coils and CYA glue (EUS-CG) is a relatively recent modality. There is limited data comparing the two techniques. Methodology: This international multicentre study included patients with GV undergoing endotherapy from two Indian and two Italian tertiary care centres. Patients undergoing EUS-CG were compared with propensity-matched E-CYA cases from a cohort of 218 patients. Procedural details such as amount of glue, number of coils used, number of sessions required for obliteration, bleeding after index procedure rates and need for re-intervention were noted. Results: Of 276 patients, 58 (male 42, 72.4%; mean age-44.3 ± 12.1 years) underwent EUS-CG and were compared with 118 propensity-matched cases of E-CYA. In the EUS-CG arm, complete obliteration at 4 weeks was noted in 54 (93.1%) cases. Compared to the E-CYA cohort, EUS-CG arm showed significantly lower number of session (1.0 vs. 1.5; p < 0.0001) requirement, lower subsequent-bleeding episodes (13.8% vs. 39.1%; p < 0.0001) and lower re-intervention (12.1% vs. 50.4%; p < 0.001) rates. On multivariable regression analysis, size of the varix (aOR-1.17; CI 1.08-1.26) and technique of therapy (aOR-14.71; CI 4.32-50.0) were significant predictors of re-bleeding. A maximum GV size >17.5 mm had a 69% predictive accuracy for need for re-intervention. Conclusion: Endoscopic ultrasound-guided therapy of GV using coil and CYA glue is a safe technique with better efficacy and lower re-bleeding rates on follow-up compared to the conventional endoscopic CYA therapy.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
