Long-term disease-free survival following preoperative diagnosis and laparoscopic radical resection for Meckel's diverticulum adenocarcinoma: A case report.

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
backgroundMeckel's diverticulum (MD) is most commonly encountered during emergency interventions for complications or as an incidental finding during an unrelated procedure. Definitive pre-operative diagnosis of MD-associated adenocarcinoma, permitting radical resection, is very rare in clinical practice. CASE SUMMARY: A 36-year-old male presented with recurrent dark-red hematochezia. Initial gastroscopy, colonoscopy, computed tomography, and tumor marker assessments were unremarkable. A technetium-99m pertechnetate Meckel scan (Meckel scan) revealed ectopic gastric mucosa, suggesting an MD. Double-balloon enteroscopy revealed an ulcerative stricture in the ileum, and biopsy confirmed a moderately differentiated adenocarcinoma. The patient underwent laparoscopic radical small bowel resection. Histopathology confirmed pT3N0M0, stage IIA (the American Joint Committee on Cancer 8
conclusionFor recurrent obscure gastrointestinal hemorrhage, combined Meckel scan and double-balloon enteroscopy is critical for diagnosing MD-associated, enabling curative resection.
