Assessment of the reproducibility of quantitative hepatobiliary scintigraphy (QHBS) in patients with sphincter of Oddi dysfunction (SOD) – Inappropriate method or intermittent dis…

Introduction: Although QHBS has been suggested as a promising screening method in pts with suspected SOD, it was recently claimed that QHBS has poor reproducibility. The aim of the present study was to assess the reproducibility of QHBS in cholecystectomized patients. Methods: 28 pts with suspected SOD underwent QHBS evaluation on two separate occasions. On the basis of the ERCP and clinical data, 10 pts were classified as having SOD of biliary type I (SO stenosis), and the remaining 18 as having SOD of biliary type II or III (SO dyskinesia). During the same period, 12 asymptomatic cholecystectomized individuals…
