Early and Direct Endoscopic Stone Removal in the Moderate Grade of Acute Cholangitis with Choledocholithiasis Was Safe and Effective: A Prospective Study.

ABSTRACT:

Background

Evidence supporting the feasibility of single-stage stone removal in patients with a moderate grade of acute cholangitis remains insufficient. The maximal size of a common bile-duct stone suitable for removal during a single-stage ERCP in a moderate grade of acute cholangitis is unknown.

Methods

We prospectively enrolled 196 endoscopic retrograde cholangiopancreatography (ERCP)-naïve patients diagnosed with acute cholangitis and choledocholithiasis. For eligible patients, single-stage treatment involved stone removal at initial ERCP.

Results

A total of 123 patients were included in the final analysis. The success rate of complete stone extraction was similar between patients with mild and moderate grades of acute cholangitis (89.2% vs. 95.9%; p = 0. 181). Complication rates were comparable between the two groups. In the moderate grade of the cholangitis group, among patients who underwent early single-stage ERCP, the length of hospitalization declined as short as the patients in the mild grade of cholangitis (10.6 ± 6.2 vs. 10.1 ± 5.1 days; p = 0.408). In the multivariate analysis, early ERCP indicated shorter hospitalization times (≤10 days) (odds ratio (OR), 3.981; p = 0.001). A stone size less than 1.5 cm presented a high success rate (98.0%) for complete stone removal.

Conclusions

Single-stage retrograde endoscopic stone removal in mild and moderate grades of acute cholangitis may be safe and effective, which can obviate the requirement for a second session, thus reducing medical expenses.
