5-10 % of women will undergo surgery for an adnexal mass 13 – 21 % of these will have an ovarian malignancy >75% of ovarian cancers are presenting with advanced disease True stage I(a) is rare < 1% of apparently benign adnexal masses are “unexpected” ovarian carcinomas The majority (>95%) of adnexal masses are benign !

The adnexal mass Laparoscopy versus laparotomy Medeiros, Int J Gynecol Cancer 2008 Systematicreview and meta-analysis • 487 trials – 23 relevant studies • Inclusion of only 6 RCT involving 324 cases Laparoscopy is associatedwithreduction: • Febrilemorbidity • Urinarytractinfection • Postoperative pain and complications • Days in hospital (-3) • Total cost • Increasedoperative time (+11min) Ph.

Rupture of an ovarian malignant tumour is a significant prognostic factor and should be avoided Laparoscopic removal of ovarian cysts should be restricted to patients with preoperative evidence that the cyst is benign The adnexal mass Laparoscopic management? Vergote, Lancet 2001 Ph. De Sutter Laparoscopic Surgery in Gynaecologic Oncology
Laparoscopic management of adnexal masses: a gold standard? The surgical diagnosis is the key to adequate management of adnexal tumours Laparoscopy and gynaecologic cancer: is it still necessary to debate or only convince the incredulous? The inadequate surgical management performed by laparoscopy as well as by laparotomy may worsen the prognosis of early ovarian cancer The prognosis of cancer is more related to itsbiologythan to the surgicalapproach The adnexal mass Laparoscopic management?
