Introduction: the interest with choledoscopy has been increased with the new videoendoscopy instruments of very small diameter provided with microchips which give better images (CCD). Patients and methods: a nasofiberscope, 5.9 mm diameter (EG530N, Fujinon-Toshiba, Tokyo, Japan) was utilized. We present 7 cases studied with choledoscopy performed with this instrument for diagnostic purposes. Discussion: it was possible to detect residual lithiasis after endoscopic procedures for the extraction of biliary stones in two cases, to confirm the absence of stones in other three cases, to diagnose with choledoscopy-guided biopsy the presence of a stenosing lesion at the hepatic hilum (tubular adenoma) and to precise the cause of dysfunction of a self-expandable metal stent. Conclusions: 1. Our initial experience with choledoscopy performed with a small caliber videoendoscope is presented. 2. The indications and eventual complications of the procedure are discussed. 3. The feasibility of the procedure and its application in the management of biliary pathology is demonstrated.
