Idiopathic acute recurrent pancreatitis (IARP) is defined as at least two episodes of acute pancreatitis with the complete or near-complete resolution of symptoms and signs of pancreatitis between episodes, without an identified cause. There is a paucity of information about the usefulness of endoscopic ultrasound (EUS) in IARP.
To determine the diagnostic yield of EUS in IARP.
A retrospective study was performed in patients with IARP evaluated by EUS between January 2009 and December 2016. Follow-up assessments of acute pancreatitis recurrence were carried out.
Seventy-three patients with 102 EUS procedures were included. EUS was able to identify the cause of IARP in 55 patients (75.3%). The most common findings were chronic pancreatitis in 27 patients (49.1%), followed by lithiasic pathology in 24 patients (43.6%), and intraductal papillary mucinous neoplasm in four patients (7.3%). A directed treatment against EUS findings had a protective tendency associated with the final resolution of recurrence. There were no complications reported.
EUS performed in patients with IARP helped to identify a possible cause in 2/3 of the cases. The majority of patients have a treatable disease.
确定超声内镜（EUS）在特发性急性复发性胰腺炎（IARP）中的诊断价值。
本研究为回顾性研究，纳入了 2009 年 1 月至 2016 年 12 月间接受 EUS 检查的 IARP 患者。对急性胰腺炎复发的情况进行随访评估。
本研究共纳入 73 例患者，共进行了 102 次 EUS 检查。EUS 能够确定 55 例（75.3%）IARP 患者的病因。最常见的发现是 27 例（49.1%）慢性胰腺炎，其次是 24 例（43.6%）胆石症，4 例（7.3%）为胰管内乳头状黏液性肿瘤。针对 EUS 发现的靶向治疗与最终缓解复发有一定的相关性。无并发症发生。
对 IARP 患者进行 EUS 检查有助于确定 2/3 患者的可能病因。大多数患者的疾病是可治疗的。
