Mayer-Rokitansky-Küster-Hauser syndrome type II complicated by strangulated left inguinal ovarian-fallopian tube hernia in a pediatric patient: a case report.
Article in BMC pediatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a congenital disorder characterized by Müllerian duct anomalies. Patients have a significantly higher incidence of inguinal hernia (6.4%-15.6%) compared to the general female population. These hernias frequently contain ovarian or tubal tissue and are associated with a high risk of strangulation, posing a threat to future fertility. This case report details a rare pediatric presentation of MRKH syndrome type II with a strangulated inguinal ovarian-tubal hernia. CASE PRESENTATION: A 7-year-5-month-old girl presented with a 28-hour history of an irreducible left inguinal mass. Ultrasound revealed a left incarcerated inguinal hernia and a right ectopic kidney. Emergency surgery confirmed a left strangulated inguinal hernia containing a necrotic ovary and fallopian tube, along with a contralateral occult hernia. Findings of uterine and vaginal agenesis with a 46,XX karyotype confirmed MRKH syndrome type II. A literature review of 24 cases (including ours) showed that inguinal hernias in MRKH are predominantly left-sided (45.8%) or bilateral (41.7%), with ovarian involvement in 87.5% of cases. In type II MRKH, renal malformations were observed in 91.7% of cases and were consistently associated with an ipsilateral inguinal hernia.
conclusionInguinal hernias in MRKH syndrome commonly involve gonadal tissue and carry a high incarceration risk. The presence of reproductive organs within a hernia sac or associated renal anomalies should raise strong suspicion for MRKH syndrome. Early diagnosis, timely surgical intervention to preserve viable ovarian tissue, and multidisciplinary management are crucial for protecting reproductive potential and improving long-term outcomes.
