DIAGNOSIS AND MANAGEMENT OF INTRADUCTAL PAPILLARY MUCINOUS NEOPLASMS: A NARRATIVE REVIEW BASED ON INTERNATIONAL GUIDELINES.
Review in Arquivos de gastroenterologia, 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
backgroundIntraductal papillary mucinous neoplasms (IPMNs) are the leading cause of incidentally detected pancreatic cysts and exhibit a wide biological spectrum with variable malignant potential. Recent advances in imaging, endoscopic assessment, molecular testing, and artificial intelligence have improved risk stratification and influenced contemporary international guidelines.
objectiveTo synthesize the most recent evidence on the diagnosis, risk stratification, and management of IPMNs, with emphasis on comparing the Fukuoka (2017), European (2018), and Kyoto (2024) guidelines, and on the integration of emerging technologies.
methodsA structured narrative review was conducted based on major international clinical guidelines and systematic reviews identified through PubMed/MEDLINE and Embase. Eligible publications in English from 2020 to 2025 addressing clinical, radiologic, molecular, and management-related aspects of IPMNs were included.
resultsDiagnosis primarily relies on magnetic resonance imaging and endoscopic ultrasound, supplemented by fine-needle aspiration, molecular analysis of cyst fluid, and emerging tools such as radiomics and artificial intelligence models. International guidelines differ in risk criteria, anatomic thresholds, and recommended surveillance intervals, directly influencing decisions between follow-up and surgical resection. Minimally invasive techniques, including EUS-guided radiofrequency ablation and intralesional chemoablation, are under investigation as alternative options for patients who are not surgical candidates.
conclusionThe management of IPMNs should be individualized and multidimensional, integrating clinical, radiologic, and molecular information within the framework of updated guidelines. Active surveillance is safe for low-risk lesions, whereas surgery remains indicated for patients with high-risk stigmata. Emerging technologies including radiomics, artificial intelligence, and next-generation sequencing, are expected to enhance diagnostic precision and support personalized therapeutic decision-making.
