  "abstract": "We read the recently published article, ‘How accurate is EUS-guided direct portal vein pressure measurement? A comparison with intraoperative measurements’ with great interest. In this article,1 Singh and colleagues compared the endoscopic ultrasound (EUS)-portal vein pressure (PVP) technique with direct intraoperative PVP measurement using a novel compact manometer (CM) and a conventional pressure transducer (CPT) connected to an ECG monitor. They found a reasonable correlation for EUS-PVP (0.72) and good correlation intraoperatively (0.96). However, the Pearson coefficient of 0.72 indicates only moderate correlation, which raises several concerns.",
