Life-Threatening Melena from Deep Ileal Angiodysplasia Successfully Treated by Intraoperative Enteroscopy-Guided Segmental Resection: A Case Report.
Article in 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
introductionSmall bowel angiodysplasia (AGD) is a common yet diagnostically challenging cause of gastrointestinal (GI) bleeding in older patients, particularly in those receiving anticoagulants. In hemodynamically unstable cases where conventional modalities fail, intraoperative enteroscopy (IOE) remains an important rescue modality. CASE PRESENTATION: An 85-year-old man receiving apixaban presented with life-threatening melena and hemorrhagic shock (hemoglobin nadir 5.5 g/dL). Esophagogastroduodenoscopy, colonoscopy, and selective mesenteric angiography were all non-diagnostic. Dynamic contrast-enhanced CTA demonstrated active contrast extravasation in the deep ileum. An emergency laparotomy with IOE was performed: a sterile upper GI endoscope was introduced through a mid-intestinal enterotomy and advanced bi-directionally; systematic intraluminal irrigation with warmed saline via a water-jet system restored clear visualization of the small bowel mucosa; and a minute, actively spurting vascular lesion was identified in the deep ileum. A targeted 10-cm segmental resection with primary anastomosis was performed. No gross abnormalities were evident in the resected specimen; however, histopathology confirmed AGD with dilated, tortuous submucosal vessels. No recurrent bleeding was observed over 1 year of follow-up.
conclusionsIOE-guided surgery is a definitive diagnostic and therapeutic option in life-threatening small bowel bleeding when standard modalities fail. Early multidisciplinary decision-making and prompt surgical intervention are essential in such high-risk older patients receiving anticoagulation therapy.
