Circumportal Pancreas-a Must Know Pancreatic Anomaly for the Pancreatic Surgeon.
Article in Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers.
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
purposeCircumportal pancreas is a rare congenital pancreatic anomaly with encasement of the portal vein and/or the superior mesenteric vein by pancreatic tissue. It is often overlooked on cross-sectional imaging studies and can be encountered during pancreatic surgery. Pancreatic head resection with circumportal pancreas is technically difficult and bears an increased risk of postoperative pancreatic fistula. MATERIALS AND
methodsA retrospective chart review of our data base for all patients who had undergone pancreatic head resection between 2004 and 2015 was performed.
resultsWe identified six patients out of 1102 patients who had undergone pancreatic head surgery in the study period. CT-scan and MRI were never able to identify circumportal pancreas prior to surgery. The right hepatic an artery derived from the superior mesenteric artery in four cases (67%). Additional resection of the pancreatic body was always performed. Postoperative course was uneventful in all cases without occurrence of pancreatic fistula.
conclusionsCircumportal pancreas is a rare entity every pancreatic surgeon should be aware of. It is difficult to identify on cross-sectional imaging studies. A right hepatic artery arising from the superior mesenteric artery should raise suspicion of circumportal pancreas. Additional pancreatic tissue resection should be performed during pancreatic head resections to avoid pancreatic fistula.
