What laparoscopic cholecystectomy involves
Under general anaesthesia, 3–4 small incisions (5–12 mm) are made in the abdomen. A high-definition camera and long instruments are passed in to dissect the gallbladder away from the liver bed and the bile ducts. The cystic duct and cystic artery are clipped and divided, and the gallbladder is extracted through the umbilical port in a retrieval bag. The whole operation takes 30–60 minutes for routine cases.
