1 · What the graph read from it

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.

2 · The registry

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

backgroundEctopic opening of the common bile duct is a rare congenital biliary anomaly. Herein, we present a case of duodenal stenosis with ectopic opening of the common bile duct into the duodenal bulb. CASE PRESENTATION: A 54-year-old man was referred with fever, nausea, and vomiting. He had experienced epigastric pain several times over the past 30 years. Endoscopy showed a post-bulbar ulcer, a submucosal tumor of the duodenum, and a small opening with bile secretion. Contrast duodenography revealed duodenal stenosis and bile reflux with a common bile duct deformity. Pancreatoduodenectomy was performed because of the clinical suspicion of a biliary neoplasm or groove pancreatitis. The resected specimen showed an ectopic opening of the common bile duct into the duodenal bulb and no tumor.

conclusionsEctopic opening of the common bile duct into the duodenal bulb is complicated by a duodenal ulcer, deformity, and stenosis mimicking groove pancreatitis or pancreatic tumors. Although rare, we should be aware of this anomaly for an accurate diagnosis.
