What is the clinical significance of “white bile” from my patient’s gallbladder drain?

“White bile” (WB) (Figure) is a clear sero-mucous secretion of gallbladder that is largely devoid of bilirubin and bile salts. It arises from glycoproteins that are normally secreted by the mucosal glands of the gallbladder infundibulum and neck, and is thought to shield the gallbladder wall from the lytic action of bile.

WB is observed in “hydrops” of gallbladder and is caused by absorption of bile by the gallbladder wall in the setting of persistent cystic duct obstruction1. It is commonly held that in persistent cystic duct obstruction, bile in the gallbladder is eventually absorbed into the lymphatics and blood vessels but that the gallbladder epithelium continues to produce clear sero-mucous secretions. In this setting, dilatation, perforation, and atrophy of the gallbladder lumen may also occur1-3.  Early cholecystostomy tube placement or cholecystectomy is often indicated1,3.

Common etiologies of persistent cystic duct blockage in adults include, stone impaction, cystic duct stenosis, tumors/polyps, and parasites (eg, ascariasis).
