Abstract
In the laparoscopic era the main goal is to provide solutions with the least possible invasion with most reliable outcomes with the least coasts. Laparoscopic CBD exploration is considered one of the corner stones in the CBD stones management and the open technique became limited to certain situations due to the high morbidity and mortality outcomes and associated prolonged hospital stay and post-operative care. The traditional choledechoscope is used on a wide range with laproscopic CBD exploration and even open method, however the unavailability of such instrument in many centers open the way to discover novel methods and instruments to take over.
The Ambu_ aScope 2TM was launched in 2009 and is now on its third generation. There have been several studies reporting the aScope use in anesthesia for difficult intubation.
Based on the close similarity to the choledecoscope a new idea to use such device in CBD exploration and evaluate such instrument in that sort of operation
The Ambu_ aScope 2TM is safe and feasible in laparoscopic common bile duct exploration. It confers significant financial benefits and offers an economical alternative to expensive reusable endoscopes. This may facilitate the wider application of common bile duct exploration as a surgical procedure. The Ambu_ aScope 2TM was approved and satisfactory to the operating surgeons as regarding the handling of the instrument, orientation, quality of image and feasibility of stone extraction through the working port. However, since the device have a connected small LCD made it difficult sometimes to have good visual access and always need someone to hold it closer to the operating surgeon.
