Current state of endohepatology: Diagnosis and treatment of portal hypertension and its complications with endoscopic ultrasound

Figure 2 Proposed algorithm for choosing suitable modality for liver biopsy. ¹Allows endoscopic exam for evidence of portal hypertension (i.e., varices/PHG), high-resolution endoscopic ultrasound images of liver contours/parenchyma, endoscopic “palpation” of the liver, bi-lobar biopsies, and direct measure of portal pressure gradient. PH: Portal hypertension; TJ-LB: Transjugular liver biopsy; EUS-LB: endoscopic ultrasound-guided liver biopsy; PPG: Portal pressure gradient; HVPG: Hepatic venous pressure gradient; PC-LB: Percutaneous liver biopsy.
