Laparoscopic resection of retro gastric extra osseous Ewing Sarcoma in a 5-year old: a rare case and review of literature.
Review in BMC surgery, 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
Ewing sarcoma is a highly aggressive pediatric bone tumor that most commonly affects children and adolescents. It is characterized by the chromosomal translocation t(11;22)(q24;q12), resulting in the EWSR1-FLI1 fusion gene, and is typically associated with strong CD99 immunopositivity. Involvement of visceral organs, particularly the gastrointestinal tract, is extremely rare and remains underreported in literature. We present a case of a 5-year-old female with an unusual retro-gastric extraosseous Ewing sarcoma (EES). The diagnosis was confirmed via histopathological analysis following clinical and radiological evaluation The patient was treated with systemic chemotherapy followed by surgical management. This case highlights a rare and atypical presentation of visceral EES originating from the stomach in the pediatric age group. Also, this case demonstrates the feasibility of laparoscopic resection in pediatric visceral EES following neoadjuvant chemotherapy.
