Spyglass® na resolução de coledocolitíase primária: um relato de caso

Introduction: Direct endoscopic observation of biliopancreatic pathways has been improved for decades, aiming at greater diagnostic and therapeutic effectiveness. In 2006, single-operator cholangioscopy (SPYGLASS®) was developed, which allows for large-stone trypsia, as well as treatment of biliary tumor tumors and strictures. Case Report: We present a case of primary choledocholithiasis by giant stone extracted after laser lithotripsy with the technique of peroral cholangioscopy by a single operator. Discussion: In the past, the choice for patients with choledocholithiasis by calculation greater than 1.5 cm was the biliodigestive derivation. Today cholangioscopy represents an important advance in therapeutic endoscopy due to the high accuracy and precision in the manipulation of the biliary tree, preventing a major surgery to be performed. Conclusion: From this case report, it can be concluded that, despite the high cost, cholangioscopy represents an innovative, accurate and low-invasive endoscopic option, capable of preventing major surgery. Ademas well suited for biliary biopsy and treatment of patients with biliary stenosis and giant stones.
