A solitary gallbladder polyp is a polypoid protrusion in the lumen of the patient’s gallbladder, which is a substantial lesion that can be classified into benign polyps (inflammatory polyps, cholesterol polyps), neoplastic polyps (adenomatous polyps), and malignant polyps, etc. Benign polyps are more common nowadays. Obesity, smoking, hyperlipidemia, hyperinsulinemia, cirrhosis and other factors may induce gallbladder polyps. Patients may present with symptoms such as epigastric stuffiness and discomfort and abdominal pain. Generally polyps that are solitary and accompanied by blood flow under ultrasound are the most dangerous. It is recommended that gallbladder polyps that are solitary and have a wide base should be treated aggressively with surgical procedures, such as laparoscopic cholecystectomy, in order to prevent malignant changes. Patients with solitary gallbladder polyps are advised to go to the hospital as soon as possible for specialized treatment.
