Gallbladder cancer itself will not cause fecal incontinence, but if the cancer is in advanced stage, the whole body organs are failing, the physical condition is poor, and the anal sphincter muscle loses its function, fecal incontinence may occur. Gallbladder cancer is a malignant tumor originated from the epithelial cells of gallbladder mucosa, with insidious onset, mostly asymptomatic in early stage, and with history of gallbladder stones or polyps. If there are recurring and difficult to relieve abdominal pain and discomfort, right upper abdominal mass and progressive jaundice, it often suggests that gallbladder cancer may occur, and the lesion often has developed to the progressive stage. With the development of the disease, symptoms such as poor appetite, dyspepsia, anemia and peritonitis may appear, and in the late stage, systemic organ failure such as itching, chest and abdominal water, incontinence and even coma may appear. Therefore, the symptoms of fecal incontinence can appear in the late stage of gallbladder cancer.
