Many cases are found incidently at the time of laparoscopic cholecystectomy.,Gallbladder cancer,Gallbladder cancer,when gallbladder cancer is found prior to surgery, rad

43、ical cholecystectomy is recommended. removal of the gallbladder, partial removal of the liver, and removal of the draining lymph glands.,When cancer is found after simple cholecystectomy, reoperation to resect part of the adjacent liver and the nearby lymph nodes may improve survival This is especia

46、,manifestation,Unfortunately, when abdominal findings do appear, it is often already an advanced disease.,diadnosis,If the above symptoms are present, the doctor may order a series of imaging investigations and other tests to find out the problem. Usually, it is still difficult to find out cancer of
