CT suggests that an enlarged gallbladder is serious. This is because an enlarged gallbladder, if not treated in time, can cause perforation of the gallbladder, pus, etc., which can be life-threatening in serious cases. Clinically, enlarged gallbladder is often caused by cholecystitis or possibly gallbladder cancer. If cholecystitis is treated in time, it can cause perforation of the gallbladder, suppuration and abdominal infection. This is an acute abdominal condition that is very urgent and critical. Gallbladder cancer is the obstruction of bile duct, which leads to the obstruction of bile secretion and can not be released in time, resulting in the enlargement of gallbladder. Gallbladder cancer is a kind of serious and higher tumor, which needs timely surgical treatment, or else it affects the survival period of patients. Therefore, patients with enlarged gallbladder are more serious and need to be treated in time. Usually, if patients have any discomfort, they should go to the hospital in time to consult the doctor and avoid carelessness so as not to delay the treatment.
