A Case of Severe Acute Pancreatitis Following Endoscopic Biopsy of the Ampulla of Vater: A Rare Adverse Event of Esophagogastroduodenoscopy.

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
Histological biopsy is essential for diagnosing ampullary tumors; however, it can occasionally result in severe adverse events. A 49-year-old male underwent esophagogastroduodenoscopic screening, which revealed an ampulla of Vater with enlargement of the oral protrusion. An endoscopic biopsy was performed; several hours later, the patient developed severe acute pancreatitis requiring hospitalization. The biopsy result was benign, and no gallstones, ductal abnormalities, or other etiologies were identified on endoscopic ultrasonography or magnetic resonance cholangiopancreatography, and the biopsy was considered the most likely trigger. The patient recovered with conservative management and was discharged on day 14. No recurrence has been observed 3 months after discharge. Although acute pancreatitis following biopsy of the ampulla of Vater is extremely rare, it can be fatal. Endoscopists should be aware of this potential risk, carefully assess the necessity of biopsy, and ensure that patients provide informed consent before the procedure.
