Abstract
BACKGROUND

Bile duct leaks (BDLs) are serious postsurgical adverse events. Typically, conservative management with abdominal drainage is the initial treatment option. However, prolonged abdominal drainage without improvement can lead to biliary stricture and delay the optimal timing of endoscopic retrograde cholangiopancreatography (ERCP).

AIM

To identify the optimal timing for ERCP and the period during which clinical observation with conservative management is acceptable, balancing ERCP success and the risk of biliary strictures.

METHODS

We conducted a multicenter retrospective study involving 448 patients with BDLs between November 2002 and November 2022. The patients were divided into four groups based on the timing of ERCP: 3 days, 7 days, 14 days, and 21 days. The primary outcome was clinical success, defined as the resolution of BDL and related symptoms within 6 months without additional percutaneous drainage, surgery, or death. The secondary outcome was incidence of biliary strictures. Univariate and multivariate logistic regression analyses were performed to identify factors associated with ERCP success and biliary stricture occurrence.

RESULTS

In a cohort of 448 consecutive patients diagnosed with BDLs, 354 were excluded, leaving 94 patients who underwent ERCP. Clinical success was achieved in 84% of cases (79/94), with a median ERCP timing of 20 days (9.5-35.3 days). Biliary strictures were identified in 29 (30.9%) patients. Performing ERCP within 3 weeks, compared to after 3 weeks, was associated with higher success rates [92.0% (46/50) vs 75.0% (33/44), P = 0.032] and a lower incidence of biliary stricture incidence [18.0% (9/50) vs 45.5% (20/44), P = 0.005]. Subsequent multivariate analysis confirmed the association with higher success rates (odds ratio = 4.168, P = 0.045) and lower biliary stricture rates (odds ratio = 0.256, P = 0.007).

CONCLUSION

Performing ERCP for BDLs within 3 weeks may be associated with a higher success rate and a lower biliary stricture rate. If patients with BDLs do not respond to conservative treatment, ERCP is suggested to be performed within 3 weeks.

Core Tip: In this multicenter study, 94 patients with bile duct leaks who underwent endoscopic retrograde cholangiopancreatography (ERCP) were retrospectively analyzed. We found that performing ERCP within 3 weeks was associated with higher success rates and a lower incidence of biliary stricture than later interventions. Multivariate analysis confirmed that early ERCP was a key factor for improved outcomes. If patients with bile duct leaks do not respond to conservative treatment, ERCP is suggested to be performed within 3 weeks.
