[When may, should, must the ovary by removed--with which technique?]

Area of Science:

• Gynecology
• Minimally Invasive Surgery
• Oncology

Background:

• Minimally invasive surgery, particularly pelviscopy, is expanding its indications.
• Ovarian cyst operations are common pelviscopic procedures.
• Accurate diagnosis of ovarian cysts relies on patient history, clinical findings, and pre-operative sonography.

Purpose of the Study:

• To evaluate diagnostic and therapeutic strategies for ovarian cysts.
• To determine the optimal approach for managing ovarian cysts, balancing minimally invasive techniques with diagnostic certainty.
• To address the challenges in differentiating benign from malignant ovarian tumors using current methods.

Main Methods:

• Review of indications for ovarian cyst management.
• Analysis of pre-operative vaginal sonography limitations.
• Description of the surgical protocol at the Department of Obstetrics and Gynecology, University of Göttingen.

Main Results:

• Vaginal sonography cannot definitively rule out malignancy.
• Pelviscopy has limitations in differentiating benign from malignant ovarian tumors and in complete tumor extirpation.
• The risk of iatrogenic rupture of early ovarian carcinoma can negatively impact prognosis.

Conclusions:

• The University of Göttingen's protocol prioritizes diagnostic accuracy for ovarian tumors.
• Sonographically suspect ovarian tumors undergo (mini-) laparotomy with immediate microscopic examination.
• Persistent or large smooth-walled unicamerate ovarian tumors (> or = 3 cm) are managed with (mini-) laparotomy and complete extirpation for microscopic examination, with pelviscopic extirpation as a possible alternative.
