This meta-analysis aims to evaluate the outcomes of endoscopic resection (ER), transduodenal ampullectomy (TDA) and pancreatoduodenectomy (PD) for both benign and malignant ampullary tumours.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A comprehensive search was performed up to 15 December 2025. Studies were included if they reported short-term outcomes including complete resection rate, recurrence, or complications of ampullary tumours after ER, TDA, or PD. Statistical analyses were performed using both random-effects and fixed-effects models to calculate pooled means. Publication bias was evaluated using funnel plots and Egger\u2019s test, and risk of bias was assessed using ROBINS-I V2.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 80 studies were included. For complete resection rate, ER showed high heterogeneity (29%\u2013100%), TDA showed a pooled rate of 90% for benign and early-stage tumours and 66% for malignant tumours, whereas PD showed 99% and 97%, respectively. ER and TDA showed both a pooled recurrence rate of 12% for benign and early-stage tumours, whereas PD showed 6%. For recurrence of malignant tumours, TDA showed high heterogeneity (48%\u201390%) whereas PD had a pooled rate of 16%. For complications, ER and PD exhibited high heterogeneity (9%\u201395% and 27%\u201398%, respectively), whereas TDA had a pooled rate of 32%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>PD provides the best outcomes in terms of complete resection and recurrence, despite higher morbidity. ER is a viable option for benign tumours, offering lower morbidity and manageable recurrence rates.
