PURPOSE: We evaluated the effectiveness of catheter-retaining balloon-occluded retrograde transvenous obliteration (BRTO).
PATIENTS AND METHODS: Patients were divided into 2 groups based on concurrent contrast imaging findings. The primary endpoint was effectiveness, the secondary endpoint was complications, and the tertiary endpoint was recurrence of esophageal varices in all cases.
RESULTS: The mean volume of EO administered was 16.43 ± 4.37 overall and was significantly lower in group 1 (40.61 ± 14.95 mL; 15 patients, 32.6%) than in group 2 (31 patients, 67.4%). The number of injections was 1.60 ± 0.63 in group 1 and 2.97 ± 0.60 in group 2, and the volume of EO used in 1 day did not differ significantly between group 1 (12.28 ± 6.48 mL) and group 2 (13.54 ± 3.12 mL). The disappearance rate of varices was significantly greater in group 1 (100%) than in group 2 (90.3%). Fever developed in 33.3% of patients in group 1 and 87.1% of patients in group 2. The rates of recurrence of esophageal varices 2, 4, and 9 years after the procedure were 34%, 48%, and 57%, respectively.
CONCLUSION: These results show that catheter-retaining BRTO is a simple and highly effective procedure for difficult cases with minor complications. Furthermore, catheter-retaining BRTO does not require a large daily dose of EO and is, therefore, an effective treatment for solitary gastric varices.
