REPEATED OVARIOTOMY. *

The necessity for repeated ovariotomy in the same patient is somewhat rare. Of 228 cases of unilateral ovariotomy performed by Spencer "Wells, recurrence in the presumably healthy ovary, necessitating a second operation, was noted in 6 cases; and of 300 cases collected by Pfannensteil in the Breslau Klinik, 6 required a second ovariotomy. Yellitz has collected 135 cases of repeated laparotomies for various causes, and in 56 of those the indication was cystic disease of the ovary, which was apparently healthy at the first operation. The interval between the two operations varies, according to Olsliausen, from six months to twenty-five years. Most are reported to have taken place within two years; although a much longer period has elapsed in some cases before the second operation was performed. Doran reports two cases of repeated ovariotomy five and fourteen years after the first operation. Dr Croom recently reported before this Society a case where he removed a large dermoid cyst of the left ovary from a patient eighteen years of age. The right ovary, apparently healthy, was not removed. Eighteen months later, the patient was readmitted to hospital on account
