[Therapy of cholesterol lithiasis with chenodeoxycholic acid (Chenoxyl)].

Chenodesoxycholic acid (500-750 mg/day Chenoxyl) was employed over a period of 9 months in the treatment of 40 patients with radiotransparent calculi in a functioning gallbladder and 8 with choledochal lithiasis. Radiological examination and complete hepatological exploration were carried out before and after the treatment in all cases. Complete dissolution was obtained in 6 and 2 cases respectively, with reduction of size in 13 and 2, and no change in 21 and 4. No significant variations were notes in the blood lipid picture or in liver function. There were no cases of diarrhoea.
