A patient with annular pancreas presenting with severe upper abdominal pain is discussed. Endoscopic retrograde cholangiopancreatography (ERCP) was diagnostic, with successful injection of major and minor papillae showing pancreas divisum, an annular duct emptying at the major papilla and changes of severe chronic pancreatitis in all duct systems. Pylorus preserving pancreatoduodenectomy gave complete pain relief. The annulus was shown immunohistochemically to be entirely of ventral gland origin. Chronic pancreatitis was histologically less severe in the dorsal gland. Antegrade dye injection with x-ray showed dorsal to ventral connection in the resected specimen.

讨论了一名患有环状胰腺并伴有严重上腹部疼痛的患者。内镜逆行胰胆管造影（ERCP）具有诊断价值，成功注射主乳头和副乳头显示胰腺分裂，一条环状导管在主乳头排空，且所有导管系统均有严重慢性胰腺炎的改变。保留幽门的胰十二指肠切除术使疼痛完全缓解。免疫组织化学显示环状结构完全起源于腹侧腺体。组织学检查显示背侧腺体的慢性胰腺炎程度较轻。切除标本的顺行染料注射及X线检查显示存在从背侧向腹侧的连接。
