Laparoscopic Common Bile Duct Exploration Using a Single-Operator Cholangioscope.

Background

Gallbladder stones are a very common disease, with a prevalence of 21.9% in Argentina. The incidence of common bile duct stones (CBDS) varies with age and with the clinical presentation; ∼3%-10% of patients with gallbladder lithiasis have concomitant choledocholithiasis. In the past decades, the development of ultrasound and magnetic resonance cholangiography and endoscopic ultrasound has expanded for the preoperative diagnosis of gallbladder lithiasis. Materials and

Methods

We describe the step-by-step technique using the single-operator cholangioscope (pSOC) (SpyGlass™ Discover; Boston Scientific, Natick, MA) under laparoscopic guidance, in a patient with huge stones in the bile duct that was treated with a choledocotomy.

Results

The patient underwent the procedure well and the closure of the bile duct was with a primary suture. The current devices, standard cholangioscopes or bronchoscopes, only have a two-way deflection. This problem might be solved with the introduction of a new pSOC device (SpyGlass Discover; Boston Scientific).

Conclusion

In conclusion, the combination of laparoscopy and pSOC is a feasible, safe, and effective technique for the treatment of CBDS, and may be considered as an alternative approach in clinical cases where gastrointestinal anatomy is altered or when endoscopic retrograde cholangio-pancreatography (ERCP) failed. pSOC has the potential to reduce peri-procedural adverse events and costs.
