自身免疫性胰腺炎(AIP)是一种自身免疫性疾病,占慢性胰腺炎病例的2%～6%,有时很难与胰腺癌鉴别。由于不同的预后以及激素疗法较外科手术对AIP治疗更有效,因此AIP的早期及时诊断至关重要。本文就AIP的定义、流行病学、发病机制、临床特点、病理、影像学特征、诊断与鉴别诊断以及治疗和预后做一综述,为临床诊治提供帮助。
Autoimmune pancreatitis (AIP) is an autoimmune disease that accounts for 2% to 6% of cases of chronic pancreatitis and is sometimes difficult to identify with pancreatic cancer. Since different prognoses and hormone therapy are more effective than surgical treatment of AIP, early diagnosis of AIP is of crucial importance. This article summarizes the definition, epidemiology, pathogenesis, clinical features, pathology, imaging features, diagnosis and differential diagnosis of AIP, as well as the treatment and prognosis of AIP to provide help for clinical diagnosis and treatment.
