What is a laparoscopic cholecystectomy and why is it necessary?

Laparoscopic cholecystectomy is the minimally invasive way of removing the gallbladder, which is located in the abdomen beneath the right side of the liver. Gallbladder problems are usually the result of gallstones. These stones may block the flow of bile from your gallbladder, causing the organ to swell. Other causes include cholecystitis (inflammation of the gallbladder) and cholangitis (inflammation of the bile duct).
