Endoscopic Versus Surgical Treatment for Ampullary Lesions: A Systematic Review With Meta-Analysis

Ampullary lesions (ALs) can be treated through either an endoscopic approach (EA) or a surgical approach (SA). However, it is important to note that EAs carry a significant risk of incomplete resection, while opting for surgical interventions can result in substantial morbidity. We performed a systematic review and meta- analysis for R0 resection, recurrence, adverse events in general, major adverse events, mortality, and length of hospital stay between SAs and EAs. Electronic databases were searched from inception to 2023. We identified nine independent studies. The risk difference was-0.32 (95% CI:-0.50,-0.15; p <0.001) for R0, 0.12 (95% CI: 0.06, 0.19; p < 0.001) for recurrence,-0.22 (95% CI:-0.43, 0.00; p 0.05) for overall adverse events,-0.11 (95% CI:-0.32, 0.10; p = 0.31) for major complications,-0.01 (95% CI:-0.02, 0.01; p = 0.43) for mortality, and-14.69 (95% CI:-19.91,-9.47; p < 0.001) for length of hospital stay. As expected, our data suggest a higher complete resection rate and lower recurrence from surgical interventions, but this is associated with an elevated risk of adverse events and a longer hospital stay.
