Abstract The gallbladder polyp detection rate has been increasing due to the growing use of abdominal imaging technology and the incidence of gallbladder polyps, occurring in 5%−10% of the global adult population [1]. Gallbladder polyps can be divided into true polyps and pseudo polyps, and the latter are more common. Pseudo polyps have no malignant potential. In contrast, true polyps can be benign or malignant, with the most common being adenomas and adenocarcinomas [2]. Prognosis worsens when the gallbladder polyp size is greater than 9 mm and/or the patient’s age is over 52 years. Invasion of the surface of the liver or gallbladder wall thickening of more than 5 mm is considered the main factor promoting the risk of malignant transformation [3]. In addition, a recent study has confirmed the association between gallbladder polyps and colorectal adenomas or adenocarcinomas [4]. Currently, the main treatment methods of gallbladder polyps include conservative therapy and surgical resection. Conservative therapies include anti-inflammatory and cholestatic drugs; albeit not a cure, these treatments relieve symptoms. Surgical treatment involves conventional surgical cholecystectomy and laparoscopic cholecystectomy. Although surgical resection can be curative, there are many shortcomings, including trauma, slow recovery, high cost and complications such as bile leakage, pneumoperitoneum, and bleeding. Therefore, a new method for the treatment of gallbladder polyps is necessary.
