A Case Report of Endoscopic Resection and Laparoscopic-assisted Retrieval of a Giant Brunner's Gland Hyperplasia.

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
A 59-year-old man presented with left upper abdominal pain. Contrast-enhanced computed tomography suggested a duodenal intussusception and a mass with mixed fat and soft-tissue density extending from the duodenal bulb to the descending duodenum. Esophagogastroduodenoscopy identified a giant pedunculated lesion originating from the posterior wall of the duodenal bulb with a focal depressed area and marked redness. Narrow-band imaging showed no obvious epithelial neoplastic changes. An upper gastrointestinal series demonstrated an elevated lesion approximately 5 cm in size. Based on these findings, we suspected giant duodenal Brunner's gland hyperplasia. Endoscopic resection was performed under general anesthesia due to the risk of intussusception and potential malignant transformation. En bloc resection was achieved using a scissor-type endoscopic device with traction, and the specimen was safely retrieved under laparoscopic assistance with gentle compression. Histopathological examination revealed lobulated proliferation of Brunner's glands with fibrous septa and adipose tissue in the submucosa, confirming duodenal Brunner's gland hyperplasia.
