Preduodenal portal vein causing symptomatic duodenal obstruction in an adult: a case report.
Article in Journal of surgical case reports, 2025. 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
Preduodenal portal vein (PDPV) is a congenital anomaly where the portal vein (PV) crosses anterior to the first part of the duodenum. It is commonly associated with other congenital anomalies, typically presenting as a duodenal obstruction in infancy. While rare, PDPV can be diagnosed in adulthood, but is usually asymptomatic and found incidentally during surgery or on imaging. We present a case of chronic postprandial abdominal pain, occasional vomiting, and early satiety in a middle-aged female due to PDPV causing a partial duodenal obstruction. She also had malrotation of the bowel, partial agenesis of the dorsal pancreas, and azygous continuation of the inferior vena cava. We performed a laparoscopic gastrojejunostomy to bypass the obstruction caused by PDPV, resolving the patient's preoperative symptoms, now with over 3 years' follow-up. Persistent and unexplained abdominal complaints in adults warrant thorough investigation for uncommon causes such as PDPV and other congenital anomalies.
