Delayed Imaging Presentation of a Symptomatic Insulinoma After Bariatric Surgery.
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 3 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
Many reports exist on hyperinsulinemic hypoglycemia after bariatric surgery, which can result in persistence of the metabolic syndrome in patients who have undergone these procedures. While the noninsulinoma pancreatogenous hypoglycemia syndrome, or nesidioblastosis, has garnered increased attention in these patients, its presentation is similar to patients with an insulinoma and this entity must therefore be evaluated and ruled out. Herein, we present a patient who developed symptoms of hypoglycemia 7 years after Roux-en-Y gastric bypass surgery. While a diagnosis of insulinoma was entertained, his laboratory values were indeterminate and imaging localization was inconclusive. Because of significant medical comorbidities, he was managed symptomatically until imaging ultimately localized a lesion in the pancreatic uncinate process consistent with an insulinoma. He subsequently underwent resection and remains disease and symptom free 1 year after surgery. This case demonstrates the diagnostic and imaging dilemma in patients with hypoglycemia after bariatric surgery and should be of interest to anyone who cares for these patients.
