{Abstract}: OBJECTIVE: Demonstrate the usefulness of using indocyanine green after laparoscopic ovarian detorsion to save the ovary.
METHODS: A step-by-step video demonstration of a surgical technique.
METHODS: Ovarian torsion is one of the most common gynecological emergencies, mainly affecting patients younger than 20 years of age [1], and causes 2% to 7% of acute abdomens [2]. It is not advisable to routinely perform ovariectomy even with a necrotic ovary appearance [1]. Furthermore only in a small percentage of cases (16%) necrosis has been confirmed histologically [2]. Some studies have demonstrated that using indocyanine green to evaluate ovarian perfusion is inexpensive, low risk, and easily reproducible [3-5].
METHODS: A 17-year-old patient was referred to our hospital for acute abdominal pain. Ultrasound revealed ovarian torsion; therefore, the patient underwent surgical treatment. During laparoscopy, the presence of a right ovarian torsion was confirmed. A lesion compatible with a hemorrhagic corpus luteum of 6 cm was present on the ovary affected. Before ovarian detorsion, indocyanine green was administered intravenously at a 0.5 mg/kg dose. The first aspect noted was the total lack of ovarian vascularization; then ovarian detorsion was performed. At this point, using technology of Rubina (KARL STORZ SE & Co. KG, Tuttlingen, Germany), it was possible to highlight the progressive ovarian revascularization. Ovarian reperfusion occurred starting from the ovarian hilum and ending at the periphery. We proceeded with enucleation of the hemorrhagic corpus luteum by stripping technique, with subsequent ovarian reconstruction with continuous 2-0 monofilament suture. Finally, we fixed the ovary to the stump of the right round ligament. The final view highlights good ovarian vascularization. No complications occurred; the patient was discharged on the first postoperative day. A 6-month follow-up ultrasound confirmed the recovery of the vascularization of ovary.
CONCLUSIONS: Using indocyanine green represents a valid option to evaluate ovarian perfusion after detorsion. It could help the surgeon decide to save the ovary and thus allow fertility-sparing surgery in more cases.
