[Liver diseases as risk factors in surgery. View points of internal medicine]

Morbidity and mortality risk is higher on patients suffering from liver disorders. Data in the literature show that elective surgery is contraindicated in acute hepatic illness. In case of liver enzyme elevations, an examination is necessary to make etiological diagnosis and assess the extent of hepatic injury. Risk of surgery is primarily in conjunction with patient's age, extent of liver and surgical disease, comorbidities and type of surgery. Among clinical and laboratory data even today one can most easily use the Child's classification or the Child-Pugh score system. In Child A patients all type of operation can be made, lethality is only slightly elevated. Mortality in Child B patient is 10-30%. In Child C patients elective surgery, except transplantation, is contraindicated.
