The application of indocyanine green fluorescent could be a useful tool during the surgical management of biliary fistulas and gallstones, focused on improving the visualization of structures and decreasing the risk of injury. Gallstone ileus is a mechanical obstruction secondary with one or more biliary stones in the small bowel or any part of the gastrointestinal tract; the stone passes through a biliary tract´s fistula.  This stone obstructs the distal ileum and the ileocecal valve in 50%–75% of the occasions, and just 4% obstructs the outlet gastric tract.  We present a case of a gallstone ileus patient, where we describe the application of the indocyanine green fluorescence that could help reduce common bile duct injuries and improve the therapeutic of these patients.
