In the simple and uncomplicated forms of ovarian cysts and tumours the operation should be almost free from risk. Many surgeons, excluding malignant conditions, have had lists of a hundred operations with no deaths. If all kinds of tumours are included as represented in the table on p. 17, a 5% mortality in experienced hands would be regarded as a good result. In general hospital work it is probably as high as 10%. With less experienced surgeons who do not perform many operations the death-rate will vary from 10 to 15%. The risks and after-consequences of ovarian operations are set forth in Chapter XI. REFERENCES DORAN, A.
