Laparoscopic cholecystectomy is a minimally invasive procedure for gallbladder removal, and one of the most common surgical procedures worldwide. While the procedure has a very high success rate, 1 in 200 patients will sustain serious bile duct injury, primarily due to misidentification of the biliary anatomy. With 800,000 procedures carried out in the United States each year that means in the U.S. alone 4,000 patients will be seriously injured.
