Introduction: Spyglass is a mono operated system recently developed for the practice of cholangioscopy that permits the direct evaluation of the biliary ducts. Objective: To demonstrate the preliminary experience in Venezuela in a public hospital with mono operated peroral cholangioscopy (Spyglass) in patients with biliary disease. Patients and Methods: Prospective study (february - april 2012), 9 patients (6 men, 3 women) mean age 50,44 years old (28-83) with biliopancreatic disease. Indications: lithiasis (3), stenosis (1), cholangitis (1) and tumors (5). Of the 9 patients, in 5 sphinterotomy was performed and 4 were previously instrumented. In 4 patients dilatation of the sphinterotomy was performed. In 7 patients (6 with stenosis, 1 with a giant biliary stone) a stent was placed (7 plastic and 1 autoexpandible) after Spyglass. Sedation monitored by anesthesiologist and prophylactic antibiotic. Results: Spyglass was performed in 9 patients (1 patient was unsuccessful due to technical problems). Spyglass could be inserted into the common bile duct in 9 patients (100%), intrahepatic ducts 3 (33.3%) and adequate visualization was acquired in 8 patients (88.9%). Findings: exophytic lesions neovascularizadas 4 (44.4%), lithiasis 1 (11.1%), stenosis 2 (22.2%), normal 2 (22.2%). In 2 patients (1 with stenosis, another with exophytic lesion) took biopsies (inflammatory and cholangiocarcinoma, respectively). There were no complications. Conclusions: Spyglass is a miniature endoscope mono operated effective in the evaluation and treatment of lithiasis and biliary lesions. There were no complications.
