Development of a method for measuring spleen stiffness by transient elastography using a new device and ultrasound-fusion method. PLoS One 2021; 16:e0246315. [PMID: 33539456 PMCID: PMC7861355 DOI: 10.1371/journal.pone.0246315] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Accepted: 01/15/2021] [Indexed: 01/06/2023] Open
Abstract
Background Hepatic venous pressure gradient (HVPG) is the gold standard index for evaluating portal hypertension; however, measuring HVPG is invasive. Although transient elastography (TE) is the most common procedure for evaluating organ stiffness, accurate measurement of spleen stiffness (SS) is difficult. We developed a device to demonstrate the diagnostic precision of TE and suggest this technique as a valuable new method to measure SS. Methods Of 292 consecutive patients enrolled in this single-centre, translational, cross-sectional study from June through September in 2019, 200 underwent SS measurement (SSM) using an M probe (training set, n = 130; inspection set, n = 70). We performed TE with B-mode imaging using an ultrasound-fusion method, printed new devices with a three-dimensional printer, and attached the magnetic position sensor to the convex and M probes. We evaluated the diagnostic precision of TE to evaluate the risk of esophagogastric varices (EGVs). Results The median spleen volume was 245 mL (range, 64–1,720 mL), and it took 2 minutes to acquire a B-mode image using the ultrasound-fusion method. The median success rates of TE were 83.3% and 57.6% in patients with and without the new device, respectively (p<0.001); it was 76.9% and 35.0% in patients with and without splenomegaly (<100 mL), respectively (p<0.001). In the prediction of EGVs, the areas under the receiver operating characteristic curve were 0.921 and 0.858 in patients with and without the new device, respectively (p = 0.043). When the new device was attached, the positive and negative likelihood ratios were 3.44 and 0.11, respectively. The cut-off value of SSM was 46.0 kPa. Data that were similar between the validation and training sets were obtained. Conclusions The SS can be precisely measured using this new device with TE and ultrasound-fusion method. Similarly, we can estimate the bleeding risk due to EGV using this method.

Spleen and Liver Volumetrics as Surrogate Markers of Hepatic Venous Pressure Gradient in Patients With Noncirrhotic Portal Hypertension. Hepatol Commun 2018; 2:919-928. [PMID: 30094403 PMCID: PMC6078215 DOI: 10.1002/hep4.1198] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2017] [Revised: 03/12/2018] [Accepted: 04/18/2018] [Indexed: 12/13/2022] Open
Abstract
Noncirrhotic portal hypertension (NCPH) is a rare disease that may lead to serious clinical consequences. Currently, noninvasive tools for the assessment of NCPH are absent. We investigated the utility of spleen and liver volumetrics as a marker of the presence and severity of portal hypertension in this population. A cohort of NCPH patients evaluated between 2003 and 2015 was retrospectively studied. The association of spleen and liver volumes with the hepatic venous pressure gradient (HVPG) level was evaluated using locally weighted scatterplot smoothing curves. A cohort of patients with viral hepatitis-related liver disease was used as controls. Of the 86 patients with NCPH evaluated during the study period, 75 (mean age, 35 ± 17; 73% males) were included in the final analysis. Patients with portal hypertension had significantly higher spleen and liver to body mass index (BMI) ratios compared to patients with HVPG <5 mm Hg (39.5 ± 27.9 versus 22.8 ± 10.6 cm3/kg/m2, P = 0.003; 91.1 ± 40.1 versus 71.4 ± 16.7 cm3/kg/m2, P = 0.014, for spleen/BMI and liver/BMI, respectively). In contrast to the patients with viral hepatitis, a positive linear correlation was observed in the NCPH cohort between spleen/BMI and liver/BMI (above a cutoff of 25 and 80 cm3/kg/m2, respectively) and HVPG level. Additionally, only in the NCPH cohort was an increase in spleen/BMI range quartile predictive of a higher prevalence of portal hypertension and clinically significant portal hypertension (trend, P = 0.014 and 0.031, respectively). Conclusion: Spleen and liver volumetrics may have utility in the assessment of NCPH as a noninvasive biomarker that can be performed using routine radiologic examinations. Further studies are needed to validate these findings. (Hepatology Communications 2018; 00:000-000).

Abstract
BACKGROUND AND STUDY AIMS Cyanoacrylate glue is recommended first-line endoscopic therapy for gastric fundal varices but it is difficult to use and carries a risk of embolization. Thrombin is preferred by many in the UK, but its effectiveness can be difficult to establish at endoscopy and the rate of re-bleeding is higher. Endoscopic ultrasound (EUS) can help assess variceal blood flow and has the potential to improve both targeting and effectiveness of injection therapy. Whereas there is already some data for its use with glue, little data currently exist in relation to its use with thrombin. PATIENTS AND METHODS We present a series of patients treated with EUS-guided thrombin injection over the last 4 years. Thrombin was injected under EUS guidance with the intention of obliterating flow within the fundal varices. Outcomes reviewed included whether haemostasis was achieved, the dose of thrombin required for endosonographic variceal obliteration, the incidence of re-bleeding, and procedural related adverse events. RESULTS Eight patients received EUS-guided thrombin: 3 with active bleeding and 5 as elective prevention. In 2/3 (66 %) patients with active bleeding haemostasis was achieved after a single dose with complete variceal obliteration. 1/3 (33 %) had no alteration in blood flow despite 10 000 IU. None of the elective prevention group had further bleeding and obliteration was observed in 4/5 (80 %). A range of 600 to 10 000 IU of thrombin was used and there were no adverse procedure-related outcomes. CONCLUSIONS Our results are promising and suggest that EUS-guided thrombin injection may have a role in managing bleeding from gastric fundal varices.

Abstract
GOAL To analyze the risk factors from radiological indices for hemorrhage in the patients with portal hypertension and weight risk factors. METHOD We retrospectively analyzed all cases of portal hypertension with hepatitis B from June 2008 to June 2014 in Nanjing Drum Tower hospital. Patients with hepatocellular carcinoma, portal vein thrombosis, or portal hypertension with other causes, such as autoimmune hepatitis, pancreatitis, or hematological diseases were excluded. RESULTS Ninety-eight patients were recruited and divided into hemorrhage and non-hemorrhage groups. There were no statistical differences in clinical indexes such as age, prothrombin time, serum albumin, serum creatinine, serum sodium, hemameba, and blood platelet count. However, the differences were statistically significant in total bilirubin, hemoglobin, and liver function with the p values of 0.023, 0.000, and 0.039 respectively. For radiological indices, hemorrhage was correlated with diameter of inferior mesenteric vein (P=0.0528), posterior gastric vein (P=0.0283), and esophageal varices scores (P=0.0221). Logistic procedure was used to construct the model with stepwise selection and finally inferior mesenteric vein, posterior gastric vein, esophageal varices, and short gastric vein were enrolled into the model. These veins were scored according to the diameters and the rates of hemorrhage were increased with the score. We then validated the model with 26 patents from July 2014 to December 2014. The AUC value was 0.8849 in ROC curves for this radiological model. CONCLUSIONS A risk model was constructed including inferior mesenteric vein, esophageal varices, posterior gastric vein, and short gastric vein. This radiological scoring model may be a valuable indicator for hemorrhage of portal hypertension.

Abstract
Endoscopic ultrasound (EUS) is continuously stepping into the therapeutic arena, simultaneously evolving in different directions, such as the management of pancreatic and biliary diseases, celiac neurolysis, delivering local intratumoral therapy, and EUS-guided endosurgery. EUS-guided vascular procedures are also challenging, considering the variety of vascular pathology, proximity of the vascular structures to the GI tract wall, high resolution, and real-time guidance offering an attractive access route and precise delivery of the intervention. The literature on vascular therapeutic EUS demonstrates techniques for the management of upper GI variceal and nonvariceal bleeding, pseudoaneurysms, and coiling and embolization procedures, as well as the creation of intrahepatic portosystemic shunts. The paucity of studies, diversity of study designs, and the number of animal model studies hamper a systematic approach to the conclusion and decision making important to clinicians and healthcare policy makers. Nevertheless, theoretical benefits and findings up to date concerning technical feasibility, efficacy, and safety of the procedures drive further research and development in this rather young therapeutic arena.

Abstract
Endoscopic ultrasonography (EUS) is used to evaluate patients with hepatobiliary diseases. The technique is useful for the diagnosis of esogastric varices in selected cases of portal hypertension, and to evaluate the pathogenic role and prognostic value of the collateral circulation in patients with this condition. When coupled with the Doppler technique, EUS can be used to guide injection sclerotherapy and to verify the obliteration of varices (particularly fundal varices) after endoscopic treatment. Hemodynamic changes induced in the collateral circulation by vasoactive drugs can also be measured with Doppler-EUS. Fine-needle aspiration under EUS guidance is useful in the diagnosis of focal liver lesions and perihepatic adenopathy, and in the evaluation of biliary tract diseases. New indications can be developed in the future after adequate experimental validation.

Abstract
BACKGROUND Patients with cirrhosis and gastrointestinal haemorrhage are a complex group with high thirty-day mortality rates. AIM To evaluate the quality of care delivered to patients admitted with gastrointestinal (GI) haemorrhage to a tertiary care centre before and after implementing a quality improvement initiative for better adherence to practice standards. METHODS This is a prospective cohort study. All patients admitted to a tertiary care centre with a GI haemorrhage and known or suspected chronic liver disease were evaluated before and after the quality improvement initiative was implemented. Interventions to improve quality of care included the delivery of educational sessions for medical practitioners, and creation and implementation of standardised admission order sets. Quality of care measures included delivery of prophylactic antibiotics (PAs) within 24 h of admission, delivery of a somatostatin analogue (SA) and use of a proton pump inhibitor (PPI); optimal care was defined as receiving all three. Secondary outcomes included hospital length of stay (LOS) and 30-day readmission rate. RESULTS In comparing the preintervention and postintervention groups, we found significant gains in delivering PAs (57% vs. 75%, P=0.05), SAs (54% vs. 76%, P=0.013) and overall optimal care (41% vs. 65%, P=0.008). Use of PPIs did not change and remained in accordance with guidelines (90% vs. 87%, P=0.67). Hospital LOS remained similar between the two groups (6.8 vs. 7.1, P=0.88), whereas the 30-day readmission decreased (41% vs. 13%, P=0.001). CONCLUSION Implementation of quality improvement initiatives, such as targeted educational efforts and standardised order sets, can improve the quality of care delivered and patient outcomes in patients with cirrhosis and GI haemorrhage.

Abstract
Complications of portal hypertension are major concerns in liver cirrhosis and significant morbidity and mortality mainly because of variceal bleeding, ascites, bacterial infections, hepatic encephalopathy, and hepatorenal syndrome. Various modalities in the diagnosis of portal hypertension are reviewed. The measurement of hepatic venous pressure gradient (HVPG) is a simple, invasive, reproducible method and regarded as the gold standard for the diagnosis and staging of portal hypertension. Other tests such as transient elastography, per-endoscopic variceal pressure measurement, endoscopic ultrasonography, and Doppler ultrasonography may be complementary and promising.
