Which surgical procedure involves the resection of the gallbladder?

The surgical procedure that involves the resection of the gallbladder is called cholecystectomy. This operation is typically performed to remove the gallbladder, often due to conditions such as gallstones, cholecystitis, or other gallbladder-related diseases. The gallbladder is a small organ located beneath the liver, and its primary function is to store bile, which helps in the digestion of fats.

Cholecystectomy can be performed using different techniques, such as laparoscopic (minimally invasive) or open surgery, depending on the specific circumstances and the patient's condition. The laparoscopic approach is the most commonly used due to its benefits, including shorter recovery time and less postoperative pain compared to open surgery.

The other surgical procedures listed do not involve the gallbladder. An appendectomy is the removal of the appendix, herniorrhaphy involves the repair of a hernia, and colectomy refers to the resection of part or all of the colon. Each of these procedures is specific to different medical conditions and anatomical structures, distinguishing them from cholecystectomy.
