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

Ampullary adenomas are precancerous lesions with a high risk of malignant transformation. Endoscopic papillectomy is the standard treatment, but the presence of adjacent cystic lesions poses a technical challenge. An 83-year-old man underwent an endoscopic examination, which revealed an ampullary tumor adjacent to a cystic lesion. Endoscopic ultrasound and MRI confirmed its cystic nature. A biopsy diagnosed an intestinal-type adenoma. The patient underwent en bloc endoscopic papillectomy with simultaneous resection of the cystic lesion. The procedure was complication free, and histopathological analysis confirmed a nonmalignant adenoma with negative resection margins. The cystic lesion was identified as a dilated glandular duct without adenomatous components. This case underscores the importance of detailed imaging for preoperative planning. En bloc endoscopic papillectomy is a feasible and safe approach for ampullary adenomas with adjacent cystic lesions. A thorough preoperative assessment and meticulous procedural planning are crucial for achieving complete resection with negative margins.
