Atypical periampullary carcinoma complicated with stones in the lower segment of common bile duct: a case report

Abstract

Periampullary carcinoma is a malignant tumor originating within 2 cm from Vater’s ampulla. In recent years， its incidence rate has been on the rise worldwide. It is difficult to diagnose because of complex anatomical position， surrounded by multiple tissues and blood vessels and nonspecific symptoms in early stage. In this article， a 65-year-old female patient with periampullary carcinoma was reported. She suffered from multiple primary diseases complicated with stones in the lower segment of common bile duct， atypical clinical manifestations， and no space-occupying lesions found by imaging examination， which increased the difficulty of diagnosis. The causes of the difficulties in the diagnosis of periampullary carcinoma and the experiences and failure patterns were analyzed，aiming to deepen the understanding of periampullary carcinoma and provide references for early diagnosis and treatment options.
