Patient: Description (onset, main symptoms, hospital visited, etc.): Female, 37 years old, had appendectomy when she was 23 years old, had liver, gallbladder and spleen ultrasound several times, no biliary polyps, but in April 2009, I had liver, gallbladder and spleen ultrasound, I was found to have cholecystitis, multiple polyps, the largest at the neck of the gallbladder was 0.4cm. On October 7, 2010, I had an ultrasound of the liver, gallbladder and spleen, which showed that I have cholecystitis, multiple polyps, and a maximum of 0.52cm x 0.56cm at the gallbladder neck. I read on the internet that multiple polyps at the neck of the gallbladder are prone to cancer, so I am worried. Hospital: Gallbladder polyps are benign lesions, but this disease can lead to gallbladder inflammation or malignant tendency; the following cases can be considered for surgical removal of the gallbladder: first, it is clear that the chance of malignant transformation increases when the gallbladder polyp is close to 1.0 cm, especially if the polyp is located in the neck of the gallbladder; multiple gallbladder polyps, less than 1.0 cm, but the patient has repeated gallbladder inflammation or combined gallbladder stones and Patients with multiple gallbladder polyps, less than 1.0 cm, but with recurrent gallbladder inflammation or combined gallbladder stones and older than 50 years old; secondly, gallbladder polyps with imaging suggesting malignant behavior; also, gallbladder polyps with gastrointestinal tract disorders and significantly elevated CEA are excluded; patients with asymptomatic gallbladder polyps less than 0.5 cm in diameter can be followed up once every six months, and if the lesions are rapidly increasing or symptoms are obvious, surgery can be chosen. Patients with hepatitis B do not affect the therapeutic management of gallbladder polyps.
