A questionnaire on ovarian cancer ascites management was sent to members of the British Gynaecological Cancer Society (BGCS), the National Gynaecological Oncology Nurses, and the Assoication of Palliative Medicine. Questions were asked on diuretics, hematologic investigations, paracentesis, and duration of stay. Nine hundred ninety-five questionnaires were distributed, of which 492 replies were received (49% response rate). Fifty-five percent of responders used paracentesis as first-line management of ovarian cancer ascites (15% diuretics). Seventy-five percent performed some blood tests in relation to paracentesis. Ultrasound was used by 43.6% during paracentesis (15.7% for direct visualization, 27.9% to mark an entry site). Seventy-seven percent used a Bonanno catheter. Eighty-three percent used no intravenous fluids during paracentesis, and there was a wide variation in the amount and rate of drainage of ascites (1 L maximum up to free drainage of all ascites, median 5 L; 0.5 L per hour to free drainage). Gynecologists tended to use more interventions (paracentesis, ultrasound, and intravenous fluids) than palliative care physicians or medical oncologists, while palliative care physicians used fewer interventions but admitted patients for longer periods of time. This identified several areas for future study: the value of hematologic investigations, the use of outpatient management for paracentesis, and the use of ultrasound and the rate of drainage of ascites.
