Step-by-step explanation:
The main term for the removal of gallbladder calculi by means of an open procedure is cholecystectomy. This surgical procedure involves the complete removal of the gallbladder to treat conditions such as gallstones. This may be done due to gallstones, inflammation, or other gallbladder-related issues. Often performed laparoscopically, the surgeon makes small incisions and uses a camera for visualization.
Cholecystectomy is a common and generally safe procedure, and the body can adapt to the absence of the gallbladder. While patients may experience changes in digestion, the procedure aims to alleviate symptoms and prevent complications associated with gallbladder disorders.
