[Classification and estimation of risks as a preoperative requirement for risk patients (author's transl)].

The increase in gynecologic surgery for groups of risk patients, who, heretofore, have been considered as inoperable, forces us to systematize our procedures by estimating the surgical risk. The general surgical risk was high in 158 patients (10%). None of these patients died as a result of surgery. Suggestions were made, based on our own experience, for the extent of preoperative diagnostics, and for the form of the classification and estimation of risks. The improved possibilities for surgery can be extended to high-risk groups only when the existing risks are correctly estimated.
