Long-term outcomes and recurrence patterns of endoscopic papillectomy for ampullary tumors: a 15-year experience from a large tertiary center in China.
Article in Surgical endoscopy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND AND
aimsEndoscopic papillectomy (EP) is an established treatment for ampullary tumors. This study aimed to analyze recurrence patterns and risk factors in a large cohort with long-term follow-up.
methodsPatients who underwent EP for ampullary tumors at a large tertiary center from January 2010 to June 2025 were retrospectively reviewed. Cumulative recurrence rates were estimated using Kaplan-Meier analysis, and Gaussian kernel density estimation was employed to explore dynamic recurrence patterns. Cox proportional hazards model was used to identify risk factors for recurrence. Sensitivity analysis was conducted in a subgroup with at least a 5-year follow-up.
resultsA total of 262 patients were enrolled, with an endoscopic treatment success rate of 85.1%. Follow-up analysis included 218 patients, and the 1-year, 3-year, and 8-year cumulative recurrence rates were 4.2, 11.5, and 14.1%, respectively. Recurrences occurred predominantly within 2-year post-procedure, peaking at 14.9 months. Carcinoma was independently associated with an increased risk of recurrence (hazard ratios = 3.878, P = 0.025). Cumulative recurrence risk was significantly higher in carcinoma than in low-grade dysplasia.
conclusionWe recommend intensified follow-up during the peak recurrence period as a reasonable strategy. Histology-based personalized surveillance is warranted in routine practice.
