The use of conservative pelvic surgery combined with intra- and postoperative antibiotic peritoneal lavage has been evaluated in 113 women with generalized peritonitis due to ruptured tuboovarian abscess. Mortality was 7.1% and hysterectomy was only required in 3% of cases. Hormonal and menstrual functions were retained in 73.5% and the potential for future pregnancy in 42.5%. Further surgery was required in 17.5% of the patients. These results are contrasted with recent series of comparable size in which the mortality and morbidity were similar but the frequency of hysterectomy ranged from 70-100%. It is concluded that hysterectomy is not necessary in the management of ruptured tuboovarian abscess if the major source of sepsis is removed and adequate peritoneal drainage is provided by the use of lavage.
