Laparoscopy combined with peritoneal cytology in staging and restaging ovarian carcinoma

The merits of laparoscopy, with inspection of the diaphragmatic leaves, and of peritoneal cytology (free fluid or washing) in staging and restaging were studied in 153 patients with ovarian carcinoma. Of 153 patients examined, 83 were new cases, 34 were restaging in patients without clinical and/or radiological signs of disease, and 36 in patients with evident disease. The conversion rate for diaphragmatic metastases alone was 6%. Information about the spread of disease (diaphragmatic metastases) was obtained in 33 new cases (39.7%). In pretreated patients, laparoscopy was positive in 4 of 34 NED restaging and in 24 of 36 ED restaging. The conversion rate for peritoneal cytology was 6.6%, but information about the cellular intraperitoneal spread of the disease was obtained in 31 new cases (37.8%). In pretreated patients, peritoneal cytology was positive in 4 of 34 NED restaging and in 13 of 36 ED restaging.
