Hepatology, in full.

Scope: this primary document covers portal hypertension and varices in cirrhosis ONLY. Everything else in the current entry (HCC surveillance, transplant referral, nutrition, vaccination, ascites/SBP/HE/HRS/ACLF management) belongs to the separate documents listed as supporting sources and must not be attributed to this guidance. Risk-stratify compensated advanced chronic liver disease (cACLD) with non-invasive tests before defaulting to endoscopy. By vibration-controlled transient elastography, liver stiffness (LSM) under 10 kPa excludes cACLD, 10 to 14.9 kPa is suggestive and warrants further testing, and 15 kPa or above rules cACLD in. Clinically significant portal hypertension (CSPH, i.e. HVPG above 10 mm Hg) is ruled in non-invasively by LSM at or above 25 kPa alone, or LSM 20 to 24.9 kPa with platelets below 150 x 10^9/L, or LSM 15 to 19.9 kPa with platelets below 110 x 10^9/L. Where spleen stiffness measurement is available, values below 21 kPa argue against CSPH and above 50 kPa argue for it. These non-invasive cutoffs are conditional probability thresholds, not universal diagnostic rules, and hold only when their derivation conditions are met. They were established in compensated advanced chronic liver disease of viral (treated or untreated HBV/HCV), alcohol-related, or non-obese (BMI under 30) MASLD etiology, and are not validated for and should not be applied to cholestatic (e.g. PBC, PSC), vascular, or other etiologies, in which different cutoffs apply. They also require a technically reliable liver stiffness measurement by vibration-controlled transient elastography, fasting, at least 10 valid acquisitions, and an IQR/median ratio below 30 percent, and are confounded by factors that raise liver stiffness independently of fibrosis, including ALT flares or acute hepatitis, extrahepatic cholestasis, hepatic congestion (right heart failure), and recent food intake; Baveno VII recommends confirming an LSM-based rule-in on a repeat measurement obtained on a separate day. The spleen stiffness cutoffs apply only to a dedicated 100 Hz spleen module, carry a higher technical failure rate, are machine-dependent, and are not interchangeable with values obtained using the standard 50 Hz liver probe. Where these population or acquisition conditions are not met, the numeric thresholds do not reliably classify CSPH, and HVPG measurement or endoscopy is required rather than a non-invasive determination. Preserve the gray zone: LSM 15 to 25 kPa without a qualifying platelet count is explicitly indeterminate (roughly 40 to 60 percent of cACLD patients) and calls for HVPG and/or endoscopy rather than assumption in either direction. Once CSPH is established, offer a non-selective beta-blocker, carvedilol preferred at 12.5 mg/day, to lower portal pressure and prevent FIRST decompensation, on the strength of PREDESCI. This is a treat-the-pressure strategy rather than a treat-the-varices one: because a patient already on NSBB for CSPH would not have management changed by the finding, screening endoscopy becomes unnecessary for most such patients. Screening EGD is still indicated where elastography is unavailable, technically difficult, or gives discordant results, and for patients who do not meet non-invasive criteria. Standard beta-blocker contraindications (severe asthma, advanced heart block, bradyarrhythmias) continue to apply. For varices needing treatment managed endoscopically, band ligation is repeated every 2 to 4 weeks until obliteration, with surveillance endoscopy at 6 months and annually thereafter. Gastric/cardiofundal varices are treated with cyanoacrylate injection or EUS-guided coil embolization rather than banding, with hepatology involvement. In acute variceal hemorrhage, consider preemptive (early) TIPS within 24 to 72 hours in high-risk patients: Child-Turcotte-Pugh class B with score above 7 and active bleeding at endoscopy despite vasoactive therapy, or CTP class C with score 10 to 13. Keep the document's own qualifier: there is no established universal MELD or CTP cutoff at which TIPS is mandatory, and the decision is case-by-case with hepatology consultation. Statin use in compensated cirrhosis is NOT a recommendation traceable to this document; the current entry's statin sentence needs its own source or removal. Verification note: the Hepatology full text is paywalled (402/403 on direct fetch). Document identity, title, year, volume, pages and authorship were confirmed via Crossref and PubMed metadata; the numeric thresholds above were corroborated from two independent peer-reviewed commentaries on this specific guidance and match the Baveno VII rule-of-five, but were not read verbatim from the primary PDF. A human should confirm the exact guidance-statement wording against the full text before this entry is treated as quotation-grade.

An elevated alkaline phosphatase should first be confirmed to be of hepatic origin: confirm with an elevated GGT, or use ALP isoenzyme fractionation or 5'-nucleotidase to separate liver from non-hepatic (e.g., bone) sources. GGT should NOT be used as a standalone screening test in the absence of otherwise-abnormal liver chemistries, and GGT is not specific (elevated in >50% of alcohol users without overt liver disease). Patients with an elevated ALP, with or without elevated bilirubin, should be tested for primary biliary cholangitis with an anti-mitochondrial antibody (AMA). Once ALP is confirmed to be of hepatic origin, obtain a liver ultrasound to assess the hepatic parenchyma and bile ducts: biliary dilatation suggests an extrahepatic cause, while a non-dilated biliary system suggests an intrahepatic cause. Patients with an elevated ALP, with or without elevated bilirubin, should also be tested for primary sclerosing cholangitis with cholangiography by MRCP (or ERCP) together with serum IgG4, because some extrahepatic cholestatic disease (e.g., PSC, HIV/AIDS cholangiopathy) may not be visible on ultrasound; a history of cholangitis or of colonic inflammatory bowel disease further raises suspicion but is not a prerequisite for obtaining cholangiography. Liver biopsy is generally not required; about 80% of isolated ALP elevations can be diagnosed from history, physical exam, routine labs, and chest X-ray.

Perform HCC surveillance in adults with cirrhosis of any etiology who are able to benefit from HCC treatment, accordingly, do not enroll patients with Child-Turcotte-Pugh class C cirrhosis unless they are candidates for (or listed for) liver transplantation, and do not surveil those with life-limiting comorbidity (life expectancy <1-2 years) that transplantation cannot remedy, and in select non-cirrhotic chronic HBV carriers at elevated risk (e.g., active hepatitis/high viral load, family history of HCC, African/African-American ancestry, Asian men >40 and Asian women >50; AASLD references risk scores such as PAGE-B but stops short of mandating a specific numeric cutoff). Surveillance is abdominal ultrasound PLUS serum AFP at ~6-month (semiannual) intervals, a change from prior AASLD guidance, which had left AFP optional (Strong recommendation). Pursue diagnostic evaluation for an AFP ≥20 ng/mL or for a rising AFP, defined as a doubling of AFP or an increase on two consecutive tests even if the absolute value is <20 ng/mL. Any suspicious ultrasound observation ≥1 cm, or an inadequate/limited ultrasound, should be evaluated with multiphasic contrast-enhanced CT or MRI interpreted with CT/MRI LI-RADS. AASLD 2023 stages confirmed HCC using the BCLC framework and links stage to therapy (curative resection, ablation, or transplantation within Milan criteria for very-early/early disease; TACE and other locoregional therapy for intermediate disease; systemic therapy for advanced disease). Its first-line systemic options for advanced HCC with preserved liver function (Child-Pugh A) are atezolizumab+bevacizumab OR durvalumab+tremelimumab (STRIDE) as preferred, with sorafenib, lenvatinib, or durvalumab monotherapy as alternatives when the preferred combinations are contraindicated. After potentially curative therapy, continue surveillance for recurrence given high recurrence risk (AASLD monitors with cross-sectional contrast-enhanced imaging, not ultrasound, in the early post-treatment period).

Diagnose MASLD by hepatic steatosis on imaging (or biopsy) plus at least one cardiometabolic criterion and exclusion of competing etiologies (significant alcohol use, other liver disease), then risk-stratify fibrosis using a sequential non-invasive approach: FIB-4 first, followed by a second-line imaging-based test (VCTE, MRE, or ELF) for indeterminate/high-risk FIB-4, with liver biopsy reserved for discordant or unclear cases. Lifestyle modification (≥7-10% weight loss, Mediterranean diet, exercise) remains the foundation for all patients. For adults with MASH and F2-F3 fibrosis identified by non-invasive tests (VCTE 8-15 kPa, MRE 3.1-4.4 kPa, or ELF 9.2-10.5) rather than biopsy, AASLD now gives dedicated, updated practice guidance on both FDA-approved pharmacotherapies: resmetirom (Oct 2024 update) and semaglutide 2.4mg/week subcutaneous (Nov 2025 update, following August 2025 accelerated FDA approval based on ESSENCE trial data: 62.9% vs 34.3% MASH resolution without fibrosis worsening; 36.8% vs 22.4% ≥1-stage fibrosis improvement). Pioglitazone or vitamin E remain options per the 2023 base guidance. Manage cardiometabolic risk with statins for ASCVD reduction plus glycemic and blood-pressure control; for semaglutide specifically, routine hepatic panels are recommended only as clinically indicated (no discontinuations for LFT elevation in ESSENCE), with monitoring for GI adverse effects and rare risks (AKI, gallbladder disease, pancreatitis, thyroid C-cell tumors, retinopathy progression, lean mass loss). HCC surveillance with ultrasound and AFP every 6 months remains indicated only if cirrhosis is present.
