Inguinal ovarian hernia on point of care ultrasound: case reports and review of the literature

The clinical value of ultrasound in assessing ovarian strangulation in female infants and toddlers with ovarian hernia

Objective

To explore the clinical value of ultrasound examination in evaluating the presence of ovarian torsion in female infants with inguinal ovarian hernia.

Methods

We conducted a retrospective analysis of 91 cases of ovarian hernia diagnosed by ultrasonography at our institution. Among them, 6 cases were identified as ovarian strangulation, while 85 cases were classified as non-ovarian strangulation. All cases underwent high-frequency ultrasound examination. We analyzed whether there were differences in the associated factors between the two groups and compared the disparities in the urgency of surgery between the two groups.

Results

Significant differences were observed between the ovarian strangulation group and the non- strangulation group in terms of ovarian volume, ovarian blood flow, and the presence of incarceration. The need for emergency surgery was significantly associated with the presence of incarceration and ovarian torsion.

Conclusion

Ultrasound has good clinical value in diagnosing ovarian hernia and determining the presence of ovarian strangulation. It can assist clinical physicians in determining the timing of surgery for children with ovarian hernia.

Diagnosis and Management of Pediatric Ovarian Torsion in the Emergency Department: Current Insights

Ovarian torsion is defined as twisting of the ovary around an axis consisting of its vascular pedicle, the infundibulopelvic ligament and the tubo-ovarian ligament, and can occur in females of any age. Torsion can be a result of ovarian mass causing asymmetry and subsequent torsion, or can be spontaneous. While ovarian torsion is a surgical emergency, early diagnosis and treatment can preserve ovarian viability even if necrosis is seen operatively. Presentation classically involves sudden onset severe abdominal pain and vomiting but diagnostic delay can follow subtler presentations. Diagnosis is most commonly based on sonographic findings, but advanced imaging such as CT or MRI may be required if sonography is not diagnostic. Treatment is surgical, with ovarian preservation preferred in almost all cases. In this review, I present the most recent evidence on epidemiology, diagnosis, and management of pediatric ovarian torsion, with a focus on point-of-care ultrasound for the emergency care provider.
