Duodeno-jejunal intussusception: an unusual manifestation of ampullary adenocarcinoma.
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
Duodeno-jejunal intussusception is highly unusual because of the retroperitoneal fixation of the duodenum, with only a limited number of cases documented in the literature. Furthermore, intussusception caused by a malignant ampullary lead point has not been reported previously. We present the case of a 58-year-old man who presented with obstructive jaundice for 8 months with no features of intestinal obstruction. Computed tomography imaging revealed dilation and deformation of the pancreaticobiliary tree due to duodenal intussusception. Intraoperative findings confirmed duodeno-jejunal intussusception with an ampullary mass acting as the lead point, which was confirmed to be adenocarcinoma upon pathological examination. The patient successfully underwent pylorus-preserving pancreaticoduodenectomy (Whipple procedure) with Child's reconstruction. Although duodenal intussusception is rarely encountered, clinicians must consider it in the differential diagnosis of unexplained biliary obstruction, even in the absence of intestinal obstruction features. A comprehensive diagnostic evaluation and tailored surgical approach are essential for optimal management.
