ABSTRACT
BACKGROUND/OBJECTIVES:
To evaluate the agreement between the imaging modalities MRI-MRCP and EUS in cystic lesions of the pancreas which were thought to be a BD-IPMN.METHODS:
Multicenter retrospective study included all patients between 2010 and 2015 with a suspected BD-IPMN who underwent an EUS and MRI-MRCP within 6 months or less of each other. Location, number, size, worrisome features and high-risk stigmata were evaluated. Interobserver agreement was evaluated by Kappa score.RESULTS:
173 patients were included (97 UHSC, 76 UCLH-RFH), mean age 65 (range 25-87 years), 66 males. When comparing both modalities there was good agreement for the location of the cyst. The median lesion size was larger by MRI-MRCP than EUS although it was not significant. With regards to worrisome features, there was moderate agreement for main PD of 5-9â¯mm and abrupt change (kâ¯=â¯0.45 and 0.52). Fair agreement was seen for the cyst wall thickening (kâ¯=â¯0.25). No agreement was seen between the presence of non-enhanced mural nodules or lymphadenopathy (kâ¯<â¯0). With regards to high-risk stigmata, poor agreement was obtained for the detection of an enhanced solid component (kâ¯=â¯0.12). No agreement was observed for main PDâ¯>â¯10â¯mmâ¯(kâ¯<â¯0).CONCLUSIONS:
In this multicentre study of patients with a BD-IPMN under active surveillance, most disagreement between these modalities was seen in the proximal pancreas. There was generally only minimal concordance between the imaging findings of EUS and MRI-MRCP for the detection of high-risk stigmata and worrisome features.Palavras-chave
