Heliyon 2024; 10:e28123. [PMID: 38665588 PMCID: PMC11043861 DOI: 10.1016/j.heliyon.2024.e28123] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 03/12/2024] [Accepted: 03/12/2024] [Indexed: 04/28/2024] Open
Abstract
Non-alcoholic fatty liver disease (NAFLD) can lead to irreversible liver damage manifesting in systemic effects (e.g., elevated portal vein pressure and splenomegaly) with increased risk of deadly outcomes. However, the association of spleen volume with NAFLD and related type 2-diabetes (T2D) is not fully understood. The UK Biobank contains comprehensive health-data of 500,000 participants, including clinical data and MR images of >40,000 individuals. The present study estimated the spleen volume of 37,066 participants through automated deep learning-based image segmentation of neck-to-knee MR images. The aim was to investigate the associations of spleen volume with NAFLD, T2D and liver fibrosis, while adjusting for natural confounders. The recent redefinition and new designation of NAFLD to metabolic dysfunction-associated steatotic liver disease (MASLD), promoted by major organisations of studies on liver disease, was not employed as introduced after the conduct of this study. The results showed that spleen volume decreased with age, correlated positively with body size and was smaller in females compared to males. Larger spleens were observed in subjects with NAFLD and T2D compared to controls. Spleen volume was also positively and independently associated with liver fat fraction, liver volume and the fibrosis-4 score, with notable volumetric increases already at low liver fat fractions and volumes, but not independently associated with T2D. These results suggest a link between spleen volume and NAFLD already at an early stage of the disease, potentially due to initial rise in portal vein pressure.

Liver-Spleen Volume Ratio as a Predictor of Native Liver Survival in Patients with Biliary Atresia. Transplant Proc 2023:S0041-1345(23)00135-5. [PMID: 37087298 DOI: 10.1016/j.transproceed.2023.03.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2023] [Accepted: 03/13/2023] [Indexed: 04/24/2023]
Abstract
BACKGROUND The appropriate timing of liver transplantation (LT) in patients with biliary atresia (BA) who survived with their native livers until adolescence remains controversial. The liver-spleen volume ratio (LSR) has been reported to be efficacious in predicting the prognosis of chronic liver disease. We investigated whether LSR could predict long-term native liver prognosis and serve as an indication for LT in patients with BA. METHODS Patients with BA who survived with their native liver until the age of 15 years were included. These patients were classified into 2 groups. The unfavorable prognosis group included patients who underwent or were awaiting LT or developed complications such as refractory cholangitis or gastrointestinal bleeding due to esophagogastric or intestinal varices. The favorable prognosis group included patients who survived with their native liver without complications. We compared the 2 groups regarding LSR, hematological, and histologic data. RESULTS Of 19 patients, 8 were in the unfavorable prognosis group, and 11 were in the favorable prognosis group. LSR was significantly lower in the unfavorable prognosis group (P = .009). Analysis of the receiver operating characteristic curve showed that the area under the curve of the LSR was 0.891, which was higher than the area under the curve of liver fibrosis markers. The optimal LSR cut-off value for predicting poor native liver prognosis was 1.97, with a sensitivity of 75.0% and a specificity of 87.5%. CONCLUSIONS The LSR reflects splenomegaly and liver atrophy. The LSR might be a reliable predictor of native liver prognosis and could guide decisions about LT in patients with BA.

The technique of 3D reconstruction combining with biochemistry to build an equivalent formula of indocyanine green (ICG) clearance test to assess the liver reserve function. BMC Surg 2020; 20:283. [PMID: 33183305 PMCID: PMC7664104 DOI: 10.1186/s12893-020-00952-z] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2020] [Accepted: 11/09/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The indocyanine green (ICG) clearance test is the main method of evaluating the liver reserve function before hepatectomy. However, some patients may be allergic to ICG or the equipment of ICG clearance test was lack, leading to be difficult to evaluate liver reserve function. We aim to find an alternative tool to assist the clinicians to evaluate the liver reserve function for those who were allergic to the ICG or lack of equipment before hepatectomy. METHODS We retrospected 300 patients to investigate the risk factors affecting the liver reserve function and to build an equivalent formula to predict ICG 15 min retention rate (ICG-R15) value. RESULTS We found that the independent risk factors affecting ICG clearance test were total bilirubin, albumin, and spleen-to-non-neoplastic liver volume ratio (SNLR). The equivalent formula of the serological index combining with SNLR was: ICG-R15 = 0.36 × TB (umol/L) - 0.78 × ALB(g/L) + 7.783 × SNLR + 0.794 × PT (s) - 0.016 × PLT(/109) - 0.039 × ALT (IU/L) + 0.043 × AST (IU/L) + 23.846. The equivalent formula of serum index was: ICG-R152 = 24.665 + 0.382 × TB (umol/L) - 0.799 × ALB(g/L) - 0.025 × PLT(/109) + 0.048 × AST(IU/L) - 0.045 × ALT(IU/L). And the area under the ROC curve (AUC) of predicting ICG-R15 ≥ 10% was 0.861 and 0.857, respectively. CONCLUSION We found that SNLR was an independent risk factor affecting liver reserve function. Combining with SNLR to evaluate the liver reserve function was better than just basing on serology.

Deep Learning Algorithm for Automated Segmentation and Volume Measurement of the Liver and Spleen Using Portal Venous Phase Computed Tomography Images. Korean J Radiol 2020; 21:987-997. [PMID: 32677383 PMCID: PMC7369202 DOI: 10.3348/kjr.2020.0237] [Citation(s) in RCA: 34] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2020] [Revised: 05/06/2020] [Accepted: 05/11/2020] [Indexed: 02/06/2023] Open
Abstract
Objective Measurement of the liver and spleen volumes has clinical implications. Although computed tomography (CT) volumetry is considered to be the most reliable noninvasive method for liver and spleen volume measurement, it has limited application in clinical practice due to its time-consuming segmentation process. We aimed to develop and validate a deep learning algorithm (DLA) for fully automated liver and spleen segmentation using portal venous phase CT images in various liver conditions. Materials and Methods A DLA for liver and spleen segmentation was trained using a development dataset of portal venous CT images from 813 patients. Performance of the DLA was evaluated in two separate test datasets: dataset-1 which included 150 CT examinations in patients with various liver conditions (i.e., healthy liver, fatty liver, chronic liver disease, cirrhosis, and post-hepatectomy) and dataset-2 which included 50 pairs of CT examinations performed at ours and other institutions. The performance of the DLA was evaluated using the dice similarity score (DSS) for segmentation and Bland-Altman 95% limits of agreement (LOA) for measurement of the volumetric indices, which was compared with that of ground truth manual segmentation. Results In test dataset-1, the DLA achieved a mean DSS of 0.973 and 0.974 for liver and spleen segmentation, respectively, with no significant difference in DSS across different liver conditions (p = 0.60 and 0.26 for the liver and spleen, respectively). For the measurement of volumetric indices, the Bland-Altman 95% LOA was −0.17 ± 3.07% for liver volume and −0.56 ± 3.78% for spleen volume. In test dataset-2, DLA performance using CT images obtained at outside institutions and our institution was comparable for liver (DSS, 0.982 vs. 0.983; p = 0.28) and spleen (DSS, 0.969 vs. 0.968; p = 0.41) segmentation. Conclusion The DLA enabled highly accurate segmentation and volume measurement of the liver and spleen using portal venous phase CT images of patients with various liver conditions.

Abstract
BACKGROUND Complications of patients with liver disease generally occurs as the consequence of advanced fibrosis and portal hypertension. Non-invasive tools to predict the complications may allow for better risk-stratification and medical management in patients with cirrhosis. The goals of this study were to determine the utility of CT-scan based liver and spleen volume measurement in association with complications and outcomes in patients with cirrhosis. METHODS Baseline demographic and clinical characteristics of 556 patients with cirrhosis who underwent CT scan of the abdomen between January 1-June 30,2009 were reviewed. Liver and spleen volume were measured using semi-automated interactive software and compared to 47 healthy controls. The association between liver and spleen volume and complications of cirrhosis was determined. Independent predictors of survival were analyzed with Cox regression model. RESULTS Patients with cirrhosis had significantly lower total and functional liver volume, larger total and functional spleen volume, and significantly lower total liver to spleen volume ratio when compared to controls. Liver volume, spleen volume, and liver to spleen volume ratio were significantly altered in patients with decompensated stage. Patients with hepatic encephalopathy had significantly lower total liver volume and spleen size was associated with the presence of esophageal varices. Patients with cirrhosis who underwent liver transplantation had significantly lower total liver volume and larger total spleen volume. However, spleen volume was not an independent predictor for mortality. CONCLUSIONS Baseline liver and spleen volume and its ratio are significantly altered in patients with cirrhosis. Spleen volume is also associated with the presence of esophageal varices.

Abstract
PURPOSE The purpose of this study was to evaluate changes in non-alcoholic fatty liver disease (NAFLD) after laparoscopic sleeve gastrectomy (LSG) using computed tomography (CT) images. METHODS We analyzed data from 57 patients who underwent LSG and had CTs performed before and after surgery. The patients included 34 women and 23 men (with an average age of 43 years); their mean preoperative weight and body mass index were 120 kg and 46 kg/m2, respectively. Obesity-related health disorders included type 2 diabetes mellitus (T2DM) in 33 patients, hypertension in 33 and dyslipidemia in 32. We diagnosed NAFLD in cases with liver to spleen ratios (L/S ratio) <0.9 on non-contrast CT images. We evaluated changes in body weights, BMIs, comorbidities, metabolic parameters, L/S ratios, and liver volumes after surgery. RESULTS The mean interval between CT scans before and after surgery was 26 months. The total weight loss and % excess weight loss were 35 kg and 72%, respectively. The remission rates for T2DM, hypertension, and dyslipidemia were 85%, 76% and 84%, respectively. After LSG, the L/S ratio increased in all the patients, while all except for one had L/S ratio >0.9. We diagnosed 33 out of 57 patients (58%) as having NAFLD before the operation. After the operation, the L/S ratios and liver volumes were not statistically different between the patients with previous NAFLD and those without it. CONCLUSION Laparoscopic sleeve gastrectomy is an effective treatment for obesity-related health disorders including NAFLD in Japanese obese patients.

Abstract
BACKGROUND The purpose of this case series is to investigate the relationship between splenic thickness (ST) and postoperative outcomes after hepatic resection in hepatitis B virus (HBV)-associated hepatocellular carcinoma (HCC) patients. METHODS The clinical data of 320 patients with HBV-associated HCC who had undergone liver resection were retrospectively analyzed. The value of ST in predicting postoperative outcomes was evaluated. RESULTS A total of 320 patients were enrolled in the study. An increase in ST was significantly associated with an increase in portal vein diameter (PVD), indocyanine green retention rate 15 min (ICG R15), and total bilirubin (TBIL); however, it was negatively correlated with platelet count (PLT). Post-hepatectomy liver failure (PHLF) occurred in 35 (10.9%) patients. Multivariate logistic regression analysis showed that ST was an independent predictor of morbidity and mortality after hepatectomy. Meanwhile, ST was associated with an almost sixfold increased risk for developing perioperative complications (OR 5.678; 95% CI 2.873 to 11.224; P < 0.001) and almost 13-fold increased risk for mortality after hepatectomy (OR 13.007; 95% CI 1.238 to 136.627; P = 0.033).The area under the receiver operating characteristic (ROC) curve (AUC) of ST for predicting the incidence of PHLF was 0.754 (95% confidence interval (CI) 0.667 to 0.841; P < 0.001), with a sensitivity of 57.1% and a specificity of 82.5%, which were significantly greater than those of the ICG R15 level (AUC 0.670; 95% CI 0.560 to 0.779; P < 0.001). The critical value of ST was 43.5 mm. CONCLUSIONS ST, which is an easy, inexpensive, and routinely available perioperative marker, showed a favorable predictive value for postoperative outcomes in HBV-associated HCC patients.
