Endoscopic Papillectomy for Ampullary Gangliocytic Paraganglioma: A Case Series and Literature Review.

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
Objective Gangliocytic paraganglioma (GP) significantly affects patients' quality of life. However, studies on endoscopic papillectomy (EP) for ampullary GP are limited. We therefore evaluated the safety and efficacy of EP for treating ampullary GP. Methods We retrospectively reviewed the clinicopathological characteristics of patients with GP who underwent EP at Nagoya University Hospital and conducted a literature survey. Results We enrolled six patients with a median tumor diameter of 17 mm. Complications related to EP were observed in three patients: two experienced bleeding, one had mild acute pancreatitis, and one had perforation (duplicate patients included), all of whom improved conservatively. Five resected specimens were confined to the submucosal layer, and one was beyond the submucosal layer. All patients were monitored without surgery, and no disease recurrence was observed after a median follow-up of 73 months. A literature review identified 14 patients, and additional surgery due to a positive vertical margin after EP revealed lymph node metastasis in 2 patients. There was no disease recurrence or death. Conclusion EP led to good long-term outcomes and effectively treated ampullary GP. Considering the potential for lymph node metastasis, additional surgery is recommended if the tumor exceeds the submucosal layer.
