[Partial ileal bypass for familial hypercholesterolemia].

The extent of reduction in cholesterol levels, the maintenance of low levels in the long-term, the morbidity and mortality as well as the acceptance of side-effects of the partial ileal bypass (PIB) is reviewed. The mean reduction in cholesterol levels following PIB was 35.2% in males and 35.8% in female patients. The reduction is significant and it is maintained over a 10-year period. The morbidity and mortality is low and side-effects are well tolerated. Our results indicate that the PIB may play an important role in the cholesterol-lowering armamentarium.
