Oesophageal varicesPortal hypertensive gastropathyOther findings
WCO had a sensitivity of 100%, specificity of 33%, PPV 100%, NPV 33% for detection of oesophageal varices compared to OGD.
WCO grading of varices was Fo n = 1, F1 n = 4, F2 n = 1, F3 n = 2. Both patients with F2 varices on WCO were treated by band ligation during OGD. Oesophageal transit time during WCO was median 6 seconds (range 3–432 seconds).
