Core Tip

Core tip: Endoscopic cholecystectomy via single port is a safety and reliable new flexible endoscopic surgery. Local injection of saline to the gallbladder bed makes it easier to resect the gallbladder bed from the liver. After complete dissection of the gallbladder bed, the neck of the gallbladder was clipped and cut safer and easier using ring-shaped thread method.
