Design: Case presentation

Setting: Operating room

Patients or Participants: 33 year old G1P1 presented with large right ovarian cyst. She presented with nausea, vomiting and sharp abdominal pain. Ultrasound showed a 15 cm right ovarian cyst with right hydrosalpinx. Tumor markers were normal (CA-125, CEA, CA 19-9).

Interventions: Laparoscopic right ovarian cystectomy

Measurements and Main Results: The case was completed without complications. Ovarian tissue is preserved after ovarian cystectomy using the blue dye technique.

Conclusion: The use of the blue dye technique promotes preservation of ovarian tissue during large ovarian cystectomy, providing a clear plane between ovarian cortex and cyst wall.
