[Rénal oxalic and gallbladder lithiasis after ileal resection for Crohn's disease: a report on one case (author's transl)].

The authors report the association, in a 64-year old man with previous large ileal resection (110 cm) for Crohn's disease, of gallstone and oxalate renal stones. The oxaluria was 60 mg per day (normal, less than 25 mg) and the fecal fat excretion was 50 g per day (normal, less than 6 g). A low--oxalate and--fat diet for 3 months reduced dramatically the steatorrhea, but was totally ineffective for the reduction of hyperoxaluria. The physiopathological mechanisms and the therapeutic consequences of these metabolic complications of ileal resections are discussed.
