Point-of-care ultrasound (POCUS) offers unique, real-time advantages for assessing liver disease, benefiting both health care providers and patients. It has been shown to enhance patient care and satisfaction across a variety of medical specialties. Although liver POCUS is practiced widely in many parts of the world, its use in the United States remains limited. Liver POCUS enables rapid assessment of specific hepatic conditions, including both vascular and parenchymal abnormalities, and can play a key role in timely management decision-making—such as guiding the use of diuretics or volume expanders. Once liver POCUS is established, ultrasonography-enabled procedures, such as procedure guidance and shear wave elastography, may be adopted and enrich the practice of hepatology in the future. This paper serves as a summary of the American Association for the Study of Liver Diseases' (AASLD) current position on liver POCUS, offering proposed imaging protocols, recommendations for training and credentialing, and practical guidelines for implementation in clinical settings.

Abstract Background Persistent organ failure (POF) is the strongest determinant of mortality in acute pancreatitis (AP). There is a paucity of data regarding the impact of different POF attributes on mortality and the role of different characteristics of systemic inflammatory response syndrome (SIRS) in the risk of developing POF. Objective We aimed to assess the association of POF dynamic features with mortality and SIRS characteristics with POF. Methods We studied 1544 AP subjects prospectively enrolled at 22 international centers (APPRENTICE consortium). First, we estimated the association of onset, duration, and maximal score of SIRS with POF. Then, we evaluated the risk of mortality based on POF onset, duration, number, type, and sequence of organs affected. Analyses were adjusted for potential confounders. Results 58% had SIRS, 11% developed POF, and 2.5% died. Early SIRS, persistent SIRS, and maximal SIRS score ≥ 3 were independently associated with higher risk of POF ( p < 0.05). Mortality risk in POF was higher with two (33%, odds ratio [OR] = 10.8, 3.3–34.9) and three (48%, OR = 20.2, 5.9–68.6) organs failing, in comparison to single POF (4%). In subjects with multiple POF, mortality was higher when the cardiovascular and respiratory systems failed first or concurrently as compared to when the renal system failed first or concurrently with other organ ( p < 0.05). In multivariate regression model, the number and sequence of organs affected in POF were associated with mortality ( p < 0.05). Onset and duration of POF had no impact mortality. Conclusion In AP patients with POF, the risk of mortality is influenced by the number, type, and sequence of organs affected. These results are useful for future revisions of AP severity classification systems.

AbstractBackground and AimThe primary aim was to validate the Pancreatitis Activity Scoring System (PASS) in a multicenter prospectively ascertained acute pancreatitis (AP) cohort. Second, we investigated the association of early PASS trajectories with disease severity and length of hospital stay (LOS).MethodsData were prospectively collected through the APPRENTICE consortium (2015–2018). AP severity was categorized based on revised Atlanta classification. Delta PASS (ΔPASS) was calculated by subtracting activity score from baseline value. PASS trajectories were compared between severity subsets. Subsequently, the cohort was subdivided into three LOS subgroups as short (S‐LOS): 2–3 days; intermediate (I‐LOS): 3–7 days; and long (L‐LOS): ≥7 days. The generalized estimating equations model was implemented to compare PASS trajectories.ResultsThere were 434 subjects analyzed including 322 (74%) mild, 86 (20%) moderately severe, and 26 (6%) severe AP. Severe AP subjects had the highest activity levels and the slowest rate of decline in activity (P = 0.039). Focusing on mild AP, L‐LOS subjects (34%) had 28 points per day slower decline; whereas, S‐LOS group (13%) showed 34 points per day sharper decrease compared with I‐LOS (53%; P < 0.001). We noticed an outlier subset with a median admission‐PASS of 466 compared with 140 in the rest. Morphine equivalent dose constituted 80% of the total PASS in the outliers (median morphine equivalent dose score = 392), compared with only 25% in normal‐range subjects (score = 33, P value < 0.001).ConclusionsThis study highlighted that PASS can quantify AP activity. Significant differences in PASS trajectories were found both in revised Atlanta classification severity and LOS groups, which can be harnessed in AP monitoring/management (ClincialTrials.gov number, NCT03075618).

Objective The aim of the study was to report the prevalence and predictors of abdominal pain and disability 1 year after an acute pancreatitis (AP) attack. Methods Patients were prospectively enrolled between December 2012 and April 2016. Enrolled subjects were contacted at a median of 13 months after enrollment. Multivariable regression models were used to determine factors independently associated with abdominal pain at follow-up. Results Response rate was 71% (110/155). Of respondents, median age was 51 years, 58% were female, and 14% had severe AP. At follow-up, 24% of patients reported abdominal pain (65% intermittent, 35% constant), 10% used analgesics regularly, and 6% had regular opioids use. Furthermore, 41% of patients experienced pain-related interference with work or daily activities, and 8% developed disability. On regression analysis, idiopathic etiology (odds ratio [OR], 3.8; 95% confidence interval [CI], 1.1–13.6) failure (OR, 3.3; 95% CI, 1.1–7.9), and recurrent AP (OR, 2.9; 95% CI, 1.1–10.6) were independently associated with abdominal pain at follow-up. Disability at follow-up was associated with younger age, current smoking, and intensive care unit admission (all P < 0.05). Conclusions Abdominal pain and disability are potential long-term sequelae of AP. Certain pre-existing factors and pancreatitis features are associated with these outcomes at one-year follow-up of AP.
