Aims:

Although temporary endoscopic biliary stenting is regarded as an effective procedure in patients with difficult common bile duct (CBD) stones, there have been few studies the effectiveness of multiple stents. This study was to investigate the effectiveness of multiple biliary stents in the treatment of difficult CBD stones.

Methods:

Patients with large (≥15 mm) and/or multiple (≥2) CBD stones too difficult to be extracted by conventional endoscopic methods were retrospectively enrolled. They were divided into two groups according to the number of stents (single vs. multiple). The two groups were compared in terms of complete clearance rate and size reduction.

Results:

A total of 46 patients (age, 73.3 ± 12.6; female, 29) were analyzed. Twenty-five patients (54.3%) had a single stent, while 21 (45.7%) had multiple stents. The mean interval to 2nd endoscopic retrograde cholangiopancreatography was 4.4 ± 6.5 months. Multiple stents group showed higher fragmentation rate (47.6% vs. 20.0%, P= 0.047) and size reduction (9.3 ± 10.3 vs. 3.6 ± 4.7 mm, P= 0.026), while the rate of complete stone clearance was not significantly different (61.9% vs. 60.0%, P= 0.895).

Conclusions:

Temporary multiple biliary stents placement was an effective method in the treatment of difficult CBD stones, which contributed to the higher fragmentation rate and size reduction compared to the single stent placement.
