White stool after partial hepatectomy may be caused by postoperative complications, such as hepatic failure, resulting in decreased bile secretion, or caused by biliary fistulae, or biliary obstruction, resulting in the inability of bile to flow normally into the intestines. 1. Liver failure: after partial hepatectomy, postoperative complications may occur, such as liver failure, due to severe impairment or loss of hepatic synthesis, excretion and biotransformation functions, unable to normally secrete bile to help digestion, so that less bile pigment in the intestinal tract, which may be manifested as white stools. 2. Bile fistula: bile fistula after surgery, resulting in bile not from the bile duct into the duodenum, can not participate in the normal metabolism resulting in white stools. 3. Biliary obstruction: the pathway of bilirubin excretion is blocked, which may be caused by postoperative infection leading to cholangitis, pancreatitis and other diseases causing biliary obstruction, bile can not flow into the intestine normally, and white stools will occur. When the white color of stool persists unrelieved after partial hepatectomy, one should consult a doctor in time to clarify the cause of the disease and then treat it aggressively.
