A gallbladder polyp without blood flow signal 11mm in diameter is generally not considered serious, but still requires surgical treatment. Gallbladder polyps without blood flow signal indicates that the polyp tissue benign may be larger, if gallbladder polyps exist clear blood flow signal, indicating that the blood supply is rich, consider the tumor is malignant. In addition, for gallbladder polyps with a diameter of 11 mm, although it can be observed clinically, for gallbladder polyps over 10 mm, it is currently recommended that patients actively undergo laparoscopic cholecystectomy for treatment, and develop postoperative treatment plans for the polyps through the intraoperative frozen pathology results and postoperative pathology examination results. Therefore, the severity of 11mm diameter gallbladder polyps with no blood flow signal needs to be judged in the context of the specific situation.
