RESUMO

INTRODUCTION: Common bile duct stones (CBDS) can spontaneously migrate through the duodenal papilla. In this case, ERCP could be unnecessary and a significant rate of complications could be avoided. In this study, we aim at retrospectively evaluating the rate of spontaneous stone passage in patients with an imaging diagnosis of CBDS and at analysing the factors associated to spontaneous stone migration. METHODS: We conducted a retrospective multi-centre analysis of patients undergoing ERCP for CBDS in a 12-month period. 1016 patients with CBDS were analysed. In all patients CBDS was diagnosed with adequate imaging methods performed prior to ERCP. ERCPs with failed biliary cannulation were excluded. Data regarding patients' characteristics, imaging findings and ERCP procedure were analysed. RESULTS: 1016 patients with CBDS undergoing ERCP were analysed (male sex 43.3%; mean age 69.9 ± 16.5 years). Diagnosis of CBDS was obtained by EUS in 415 patients (40.8%), MR in 343 (33.8%), CT in 220 (21.7%), and US in 38 (3.7%). No stones were found at ERCP in 179 patients (17.6%), in 14 (6.2%) when ERCP was performed within 6 h from imaging study, in 114 (18.5%) between 7 h and 7 days, in 32 (24.6%) between 8 and 29 days, and in 19 (43.2%) after 30 days. The rate of unnecessary ERCP occurred significantly more frequently in patients in whom imaging methods demonstrated either sludge or ≤ 5 mm CBDS (29.9 vs. 8.3%; p < 0.001). DISCUSSION: Spontaneous migration of small CBDS is a frequent event, and ≤ 5 mm size and a delay in ERCP > 7 days represent predictive factors for it. We suggest that CBDS ≤ 5 mm should not undergo immediate removal and this fact would allow reducing the rate of unnecessary ERCP with their related complications. Prospective studies are needed to confirm these results and demonstrate the safety of a conservative management in this setting.

RESUMO

BACKGROUND: Retreatment for 6 months with the association ribavirin-interferon of HCV-related chronic active hepatitis relapser patients has high probability of failure, mostly in those with genotype 1b. We evaluated the efficacy of extending the therapy from 6 to 12 months without or with the addition of amantadine. METHODS: Forty-nine genotype 1b relapser patients were treated with 3 MU of IFN-alpha2b three times per week and ribavirin 1000-1200 mg daily (double therapy). Twenty-four patients, who did not respond after 6 months of treatment, were randomized to continue for further 6 months either with the same schedule or with also the addition of amantadine 200 mg daily (triple therapy). RESULTS: A sustained virological response was observed in 15/37 subjects (41%) treated for 12 months of double therapy. In the arm of the study evaluating amantadine, end of treatment virologic response was observed in 0/12 patients of double therapy group and in 4/12 of triple therapy (P=0.09). After 6 months of follow-up, a sustained virologic response (SVR) was observed in two patients treated with the triple therapy. CONCLUSIONS: This study confirms poor results of retreatment (even if 12 months double or triple therapy) in relapser patients with HCV hepatitis, genotype 1b. No gain was obtained in prolonging from 6 to 12 months the standard double therapy, while triple therapy with amantadine as an additional regimen for this difficult subgroup of patients showed some cases of SVRs: amantadine addition deserves to be evaluated in larger trials.
