Femoral hernia with an incarcerated appendix epiploica mimicking a hydrocele of the canal of Nuck: a case series.
Article in Journal of surgical case reports, 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
In women, inguinal hernias that involve incarceration of intraperitoneal tissues can cause a hydrocele, which can be difficult to distinguish from a hydrocele of the canal of Nuck (HCN). We describe two cases in which an appendix epiploica (AE) became incarcerated in a femoral hernia, causing a hydrocele. In both cases, computed tomography indicated HCN as a differential diagnosis. Ultrasonography revealed protruding adipose tissue within the inguinal hydrocele, which was considered different from HCN. We performed laparoscopic surgery to diagnose, and found the AE incarcerated in femoral hernia. We released the AE, then the inguinal hydrocele completely disappeared. We performed transabdominal preperitoneal repair using mesh, and both patients experienced a favorable postoperative course. Inguinal hydrocele may be due to incarceration of an AE into a femoral hernia. By combining computed tomography and ultrasonography, the appropriate diagnosis and surgical procedure can be selected.
