Gallstones are hardened deposits of digestive fluid that form in the gallbladder. When they cause pain, infection, or other complications, surgical removal of the gallbladder (cholecystectomy) is the most effective treatment. The surgery can be performed in two ways: laparoscopic (minimally invasive) or open surgery. Laparoscopic cholecystectomy is the preferred method due to its faster recovery, less pain, and smaller scars. However, open surgery may be required in complex cases. Recovery typically takes a few days to weeks, depending on the surgical approach. After surgery, the liver continues to produce bile, and most people can lead a normal life with dietary modifications if needed.
