説明

<p>Pancreaticoduodenectomy (PD) is the standard treatment for duodenal cancers suspected of submucosal invasion. Pathological diagnosis from duodenal biopsy samples has some limitations. We present the case of a man in his 70s with bile duct dilation and a suspected parapapillary duodenal cancer. Given the uncertainty of the biopsy, endoscopic submucosal dissection (ESD) was performed as a minimally invasive diagnostic alternative to PD. Histological diagnosis revealed an adenomyoma with high-grade adenoma, underscoring the efficacy of ESD in accurately diagnosing periampullary lesions. For patients with periampullary lesions, this case suggests that ESD could serve as a less invasive approach, potentially avoiding overtreatment, such as radical surgery.</p>
