In patients with malignant biliary and duodenal obstruction (MBDO), biliary and duodenal double stenting is necessary. However, whether the time to recurrent biliary obstruction (TRBO) can be extended with ERCP-guided biliary drainage (ERCP-BD) or EUS-guided BD (EUS-BD) has not been sufficiently elucidated. Therefore, the aim of this study was to determine whether ERCP-BD or EUS-BD was more useful for increasing the TRBO with duodenal stenting.
We compared the TRBO with duodenal stenting and other clinical outcomes between ERCP-BD and EUS-BD in MBDO patients. We matched the patient characteristics of the two groups using propensity scores.
Technical success was greater in the EUS-BD group ( = 17/17, 100%) than in the ERCP-BD group ( = 32/52, 61.5%) ( < 0.01). After propensity score matching, 17 matched pairs were included for further analysis. There was no significant difference in the TRBO following duodenal stenting between the ERCP-BD group (median of 62 days) and the EUS-BD group (median of 68 days) ( = 0.94).
The TRBO following duodenal stenting was comparable between ERCP-BD and EUS-BD. The technical success of EUS-BD was superior to that of ERCP-BD; therefore, EUS-BD might be the optimal choice for endoscopic BD in MBDO patients.
