Intraoperative ultrasonography has facilitated the localization of insulinomas. In this report, we describe a patient who was found to have an insulinoma in association with an annular pancreas. Because such tumors can be in close approximation to major pancreatic ductal structures, intraoperative ultrasonography can be useful for not only localizing the lesion but also delineating the related anatomic features. Although the optimal management of an asymptomatic annular pancreas has not been determined, our patient had no evidence of chronic pancreatitis and no narrowing of the duodenal lumen; therefore, no bowel bypass procedure was done.
术中超声检查有助于胰岛素瘤的定位。在本报告中，我们描述了一名被发现患有胰岛素瘤并伴有环状胰腺的患者。由于此类肿瘤可能紧邻主要胰管结构，术中超声检查不仅有助于病变定位，还能清晰显示相关的解剖特征。尽管无症状环状胰腺的最佳治疗方案尚未确定，但我们的患者没有慢性胰腺炎的证据，十二指肠腔也未变窄；因此，未进行肠道旁路手术。
