BACKGROUND: Patients with hepatocellular carcinoma (HCC) and cirrhosis can present with features of severe portal hypertension, which can be worsened further by portal vein tumoral thrombosis (PVTT). Due to the technical difficulties and short survival of these patients, HCC was traditionally considered a relative contra-indication for transjugular intrahepatic portosystemic shunt (TIPS). However, there is an increasing body of evidence, mainly from China, supporting the use of TIPS in HCC. The present study aimed at analyzing the efficacy and safety of TIPS in patients with HCC. METHODS: From 2000 through May 2023, MEDLINE, Embase and Scopus were searched for studies analyzing the outcome of TIPS in HCC. Technical and clinical success, adverse events (AE) and mortality were the main outcomes assessed. With the use of a random effects model, the event rates were combined. RESULTS: Total 19 studies with 1498 patients were included in the final analysis. The pooled technical and clinical success rates with TIPS in HCC were 98.8% (98.0-99.7) and 94.1% (91.2-97.0), respectively. After TIPS, ascites was controlled in 89.2% (85.1-93.3) of the cases, while rebleeding was observed in 17.2% (9.4-25.0) of cases on follow-up. The pooled incidence of overall AE, serious AE and post-TIPS hepatic encephalopathy (HE) was 5.2% (2.5-7.9), 0.1% (0.0-0.4) and 25.1% (18.7-31.5), respectively. On follow-up, 11.9% (7.8-15.9) of the patients developed shunt dysfunction requiring re-intervention. CONCLUSION: The present analysis supports the feasibility, safety and efficacy of TIPS in the management of portal hypertension in patients with HCC.

Peroral endoscopic myotomy (POEM) is the preferred endoscopic modality for managing achalasia cardia. However, there are no recommendations on the role of POEM in nonachalasia esophageal dysmotility disorders (NAEMD), including esophagogastric junction outflow obstruction (EGJOO), distal esophageal spasm (DES), and hypercontractile esophagus (HE). The present systematic review and meta-analysis aimed to assess the safety and efficacy of POEM in the treatment of NAEMD. MEDLINE, Embase, and Scopus were searched from inception to August 2023 for studies analyzing the outcome of POEM in NAEMD. Clinical success and adverse events were the main outcomes assessed. The event rates and their 95% confidence interval were calculated using a random effects model. A total of 11 studies with 271 patients were included in the final analysis. The pooled clinical success rate with POEM in NAEMD was 86.9% (82.9-90.9). On subgroup analysis, the pooled clinical success rates of POEM in DES and EGJOO were 97.8% (90.9-100.0) and 92.7% (86.3-95.1), which were significantly higher than in HE 81.2% (73.5-88.8). Data from limited studies showed that the pooled rate of improvement in dysphagia and chest pain was 88.5% (83.0-93.9) and 87.4% (80.5-94.4). The pooled incidence of overall AEs and serious AEs was 12.6% (5.7-19.5) and 0.3% (0.0-1.9), respectively. On follow-up, the pooled incidence of new-onset heartburn was 18.7% (11.1-26.2). POEM is a safe and efficacious treatment modality for the management of NAEMD with a lower clinical success in patients with HE. Further large-scale studies are required to validate the findings of the present analysis.

PURPOSE: In patients with acute necrotizing pancreatitis (ANP), the site, size, and the number of acute necrotic collections (ANC) may determine the outcome of patients. The current study aimed to correlate the nature of ANC with the adverse outcomes in ANP patients. METHODS: This was a single-center, prospective study (August 2019-August 2022) recruiting patients with ANP, correlating the site, size, and number of ANC with the length of hospital stay, intensive care unit (ICU) stays, development of organ failure and infection, need for intervention, and mortality. RESULTS: A total of 114 patients (mean age: 37.3 ± 13.4 years, 85.1% males) with ANP were included in the study. The number and maximum diameter of collections significantly correlated with the length of the hospital and ICU stay and the need for intervention. Taking a cut-off size of 8 cm, the sensitivity and specificity for predicting the need for intervention were 82.7% and 74.2%, respectively. ANCs located in the perinephric, paracolic, subhepatic, and epigastric regions had a significant correlation with two or more adverse outcomes. Additional points were added to the modified CT severity index (mCTSI) based on the present study's findings. The new score had significantly higher AUROC than mCTSI for predicting infection, need for intervention, ICU stay > 1 week, and mortality. CONCLUSION: The site, size, and number of EPNs have a significant correlation with adverse clinical outcomes in patients with ANP. The inclusion of these parameters, along with present scoring systems, will help further improve the prognostication of patients.

Hepatocellular carcinoma (HCC) is the most common form of primary liver cancer and is a significant cause of morbidity and mortality, especially in patients with chronic liver disease. As a reflection of geographical variations in India, there is significant variation in the prevalence and etiological factors of HCC. In contrast to previous studies reporting viral hepatitis as the most common etiology, recent data indicates a changing etiological pattern of cirrhosis and HCC, with alcohol and metabolic dysfunction-associated steatotic liver disease (MASLD) emerging as the foremost cause. Thus, there was a need for an updated review of the current literature and databases for the changing epidemiology and etiological spectrum of HCC in India. The review included data primarily from the National Cancer Registry Program and the Global Burden of Diseases, Injuries, and Risk Factors Study, with the inclusion of other studies from India. The highlights of the present review are summarized in the following lines. Although the current incidence (2.15 per 100,000), prevalence (2.27 per 100,000), and mortality (2.21 per 100,000) rate of HCC in India remain lower compared to the global data, the annual rates of change in these parameters are higher in India. Among Indians, the present incidence, prevalence, and mortality related to HCC are higher in males, while the annual rate of change is higher in females. The Northeastern states have higher incidence, prevalence, and mortality related to HCC, but the Western states of Gujarat, Maharashtra, Goa, and Kerala are emerging as newer hotspots with higher annual rates of change in incidence, prevalence, and mortality. The incidence of HCC related to hepatitis B is on a downtrend, while those related to alcohol and MASLD are rising. Public health initiatives, awareness campaigns, and focused treatments are all necessary to combat these changes, particularly in areas with high incidence rates.

Introduction: During last few decades, radiological interventions have played crucial role in the management of the patients with chronic liver diseases. Various procedures including transjugualar intrahepatic portosystemic shunt (TIPS), transjugular liver biopsy (TJLB), transarterial chemoembilization (TACE)/transarterial radioembolization (TARE), balloon retrograde transvenous obliteration (BRTO) and plug-assisted retrograde transvenous obliteration (PARTO) are being performed safely and have significantly improved clinical outcomes in these patients. The technical and clinical success depend on appropriate patient selection along with thorough knowledge and experience to perform these procedures. On the other hand, few adverse events may also be associated with these procedures. The intervention radiologist and hepatologists should identify and treat these complications at the earliest so as to improve outcome of the patient. Materials and methods: About 25 hepatic intervention radiology procedures were performed in our center from January 2022 to 2023 May. Among these we have selected five patients who underwent TACE/TIPS/DIPS in our institute. We have selected these cases as in each of these cases we encountered some interesting outcomes/complications which were managed successfully. Results: The first case describes 33-year-old male with POEM syndrome and Budd Chiari Syndrome (BCS) who underwent TIPS and immediately had blockade of the stent. The second case is of a 43 years old male having BCS, refractory ascites with umbilical and inguinal hernia. The third case is of a 40 years old female with decompensated cirrhosis who underwent TIPS for portal hypertensive gastropathy. The fourth case is of a 51-years' female with decompensated cirrhosis with sarcopenia. Finally, the fifth case describes 24-year-old female with BCS and hepatocellular carcinoma. In this article we discuss the procedure and clinical course of the patients following the procedure. Conclusion: Hepatic radiological interventions though widely used can be associated with unusual albeit life threatening complications. Appropriate patient selection and thorough knowledge of procedure along with early diagnosis and management of these complications are key to obtain satisfying long term outcomes.

The staging of malignancy is critical for its effective management. 18F-fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET/CT) imaging is a common modality for malignancy staging, which identifies areas of FDG avidity. However, multiple benign etiologies can cause false-positive 18F FDG-avid nodes. Among these, extrapulmonary involvement of anthracosis in the form of lymphadenopathy is a rare entity. In patients with concomitant malignancies, the presence of 18F FDG-avid anthracotic lymph nodal enlargement may mimic nodal metastasis. Endosonography-guided tissue acquisition may help differentiate between the two. Herein, we describe six cases of FDG-avid benign anthracotic lymphadenitis detected during staging workups for patients with malignancies who later underwent curative resection.

BACKGROUND: The technical and clinical effectiveness of endoscopic ultrasonography (EUS)-guided gastroenterostomy (GE) has been reported by several meta-analyses, but few of them have addressed the adverse events (AE). The goal of the current meta-analysis was to analyze the AEs associated with various types of EUS-GE. METHODS: All relevant studies reporting the AEs with EUS-GE were searched from 2000 to 31st March 2023 in MEDLINE, Embase, and Scopus. The event rates were pooled using a random effects model. RESULTS: A total of 36 studies (n = 1846) were included in the meta-analysis. The present meta-analysis reports a pooled technical success rate of 96.9% (95.9-98.0; I2 = 29.3%) with a pooled clinical success rate of 90.6% (88.5-92.7; I2 = 60.9%). The pooled incidence of overall AEs with EUS-GE was 13.0% (10.3-15.7; I2 = 69.7%), with the commonest being maldeployment of the stent, seen in 4.6% (3.2-6.0; I2 = 50.6%). The pooled incidences of serious AE and procedure-related mortality were 1.2% (0.7-1.8; I2 = 1.9%) and 0.3% (0.0-0.7; I2 = 0.0%), respectively. Subgroup analysis of studies using only the free-hand technique showed a significantly lower overall AE and maldeployment but not serious AE and other individual AEs. The pooled incidences of delayed stent migration and stent occlusion were 0.5% (0.0-1.1; I2 = 0.0%) and 0.8% (0.2-1.3; I2 = 0.0%), respectively. CONCLUSION: Despite a technical and clinical success rate of >90%, AEs are seen in around one-seventh of the cases of EUS-GE, maldeployment being the commonest. However, the pooled incidence of serious AE and mortality remains low, which is reassuring.

Lumen-apposing metal stents have ushered a new frontier for interventional endoscopic ultrasound. Initial use for the drainage of pancreatic fluid collections has rapidly expanded to the bile duct, gallbladder and small bowel. Intra-luminal applications for short strictures have also emerged. Electrocautery enhancement has made the stent delivery speedy. While the advent of lumen-apposing metal stents (LAMS) has brought a paradigm shift in the practice of interventional endoscopic ultrasound, their use is associated with certain technicalities that any advanced endosonologist should know. Understanding indications for LAMS is critical and their use in appropriate settings. Troubleshooting in tricky situations is always a challenge and the background considerations for their use include knowing the target organ, cautery and puncture technique, managing partially opened LAMS and also managing maldeployment. In this review, we discuss the intricacies and technical tips for the use of lumen-apposing metal stents.

BACKGROUND OBJECTIVES: Alcohol is one of most common aetiologies of cirrhosis and decompensated cirrhosis is linked to higher morbidity and death rates. This study looked at the outcomes and mortality associated risk variables of individuals with alcoholic cirrhosis who had hospitalization with their first episode of decompensation. METHODS: Individuals with alcoholic cirrhosis who were hospitalized with the first episode of decompensation [acute decompensation (AD) or acute-on-chronic liver failure (ACLF)] were included in the study and were prospectively followed up until death or 90 days, whichever was earlier. RESULTS: Of the 227 study participants analyzed, 167 (73.56%) and 60 (26.43%) participants presented as AD and ACLF, respectively. In the ACLF group, the mortality rate at 90 days was higher than in the AD group (48.3 vs 32.3%, P=0.02). In the AD group, participants who initially presented with ascites as opposed to variceal haemorrhage had a greater mortality rate at 90 days (36.4 vs 17.1%, P=0.041). The chronic liver failure-consortium AD score and the lactate-free Asian Pacific Association for the study of the Liver-ACLF research consortium score best-predicted mortality in individuals with AD and ACLF. INTERPRETATION CONCLUSIONS: There is significant heterogeneity in the type of decompensation in individuals with alcoholic cirrhosis. We observed significantly high mortality rate among alcoholic participants hospitalized with initial decompensation; deaths occurring in more than one-third of study participants within 90 days.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) includes a spectrum of conditions, progressing from mild steatosis to advanced fibrosis. Sarcopenia, characterized by decreased muscle strength and mass, shares common pathophysiological traits with NAFLD. An association exists between sarcopenia and increased NAFLD prevalence. However, data on the prevalence of sarcopenia in NAFLD and its impact on the outcomes of NAFLD remain inconsistent. AIM: To analyze the prevalence and outcomes of sarcopenia in patients with NAFLD. METHODS: We conducted a comprehensive search for relevant studies in MEDLINE, Embase, and Scopus from their inception to June 2023. We included studies that focused on patients with NAFLD, reported the prevalence of sarcopenia as the primary outcome, and examined secondary outcomes, such as liver fibrosis and other adverse events. We also used the Newcastle-Ottawa scale for quality assessment. RESULTS: Of the 29 studies included, the prevalence of sarcopenia in NAFLD varied widely (1.6% to 63.0%), with 20 studies reporting a prevalence of more than 10.0%. Substantial heterogeneity was noted in the measurement modalities for sarcopenia. Sarcopenia was associated with a higher risk of advanced fibrosis (odd ratio: 1.97, 95% confidence interval: 1.44-2.70). Increased odds were consistently observed in fibrosis assessment through biopsy, NAFLD fibrosis score/body mass index, aspartate aminotransferase to alanine aminotransferase ratio, diabetes (BARD) score, and transient elastography, whereas the fibrosis-4 score showed no such association. Sarcopenia in NAFLD was associated with a higher risk of steatohepatitis, insulin resistance, cardiovascular risks, and mortality. CONCLUSION: This systematic review highlights the critical need for standardized diagnostic criteria and measurement methods for sarcopenia in NAFLD patients. The variability in study designs and assessment methods for sarcopenia and liver fibrosis may account for the inconsistent findings. This review demonstrates the multidimensional impact of sarcopenia on NAFLD, indicating its importance beyond liver-related events to include cardiovascular risks, mortality, and metabolic complications.

Infection by dengue virus is common in tropical countries. Hepatic involvement in dengue can range from asymptomatic elevation of transaminases to life-threatening acute liver failure (ALF). Dengue-related ALF (DALF) is responsible for significant morbidity and mortality, especially in Southeast Asia. However, there is a scarcity of literature on DALF, necessitating a thorough examination of its clinical determinants and management strategies. All relevant studies related to DALF were reviewed until December 2023. Case reports, case series and studies reporting ALF in dengue infection were included. Demographics, clinical profiles, management and outcomes of DALF cases were analyzed, which revealed a predominance of DALF incidence in pediatric patients (1.1% to 15.8%) and an upward trend over the years, particularly in India. The proportion of ALF cases attributable to dengue was also higher among pediatric ALF patients (6.7% to 34.3%). Age ≤ 40 years, persistent nausea, vomiting and elevated serum bilirubin and alkaline phosphatase (ALP) with aspartate aminotransferase (AST) > 1000 IU/mL within the first five days of illness, more than 10% of atypical lymphocytes in peripheral blood, platelet count of < 50,000/cu·mm, severe hepatitis at presentation and baseline model for end-stage liver disease (MELD) > 15 were the risk factors for the development of DALF. Histopathological features of DALF included multi-lobular hepatic necrosis, steatosis and occasional cholestasis. Mortality in DALF ranged from 0% to 80%; admission pH and lactate strongly predicted mortality, while mortality was found to be significantly higher in patients with cirrhosis. N-Acetyl cysteine (NAC) has been used as a treatment modality with varying results. There is limited evidence regarding the use of extra-corporeal support systems, while candidate selection for liver transplantation (LT) in DALF remains poorly defined.

Background: Recent studies from both India and outside India have shown a change in the etiological profile of hepatocellular carcinoma (HCC). We aimed to analyze the etiological spectrum and changing trends of HCC etiology in India using a systematic review of current literature and meta-analysis. Methods: Electronic databases of PubMed/Medline, Scopus, and Embase were searched from inception to July 2023 for studies reporting the data on the etiology of HCC from India. The pooled proportions with 95% confidence interval were calculated using summative statistics. Results: A total of 60 studies (n = 12,327) were included in the final analysis. The pooled proportions of HCC cases with at least one positive and negative viral marker were 56.0 (49.5-62.6) and 43.1% (36.5-49.8), respectively. The pooled proportion of HCC cases with positive hepatitis B virus (HBV) markers was 41.0 (35.8-46.1), while those with positive markers for hepatitis C virus were 20.3 (17.0-23.6). The pooled proportion of cases with HCC with significant alcohol intake was 19.0% (15.6-22.4), and those related to nonalcoholic fatty liver disease (NAFLD) were 16.9% (12.1-21.7). Around 7.9% (5.8-10.0) of the cases had HCC with multiple etiologies. Subgroup analysis showed a significant variation with the location of the study based on zone. Meta-regression analysis based on publication year (1990-2023) showed a significant reduction in the proportion of cases with HBV and an increase in cases with NAFLD. In contrast, the proportion of cases with hepatitis C virus and alcohol did not change significantly. Conclusion: Viral hepatitis is the most common etiology of HCC in India, predominantly HBV. The proportions of cases with HCC related to NAFLD are increasing, and those related to HBV are declining.

Introduction/Purpose: Patients with cirrhosis and hepatocellular carcinoma (HCC) can develop both benign and malignant portal vein thrombosis (PVT). Characterising the nature of PVT is important for planning an optimal therapeutic strategy. In the absence of typical findings or contraindications to computed tomography (CT) or magnetic resonance imaging (MRI), contrast-enhanced ultrasound (CEUS) could help in this differentiation. The present meta-analysis aimed to evaluate the performance of CEUS for characterising PVT in patients with HCC. Methods: Electronic databases of PubMed, Embase and Scopus were searched from inception to 31 December 2022 for studies analysing the role of CEUS in the differentiation of benign and malignant PVT in HCC. Using the bivariate random effect model, pooled sensitivity and specificity were calculated, and the summary receiver operating characteristic (sROC) curve was plotted. Results: A total of 12 studies with data from 712 patients were included in the meta-analysis. The pooled sensitivity and specificity of CEUS for the diagnosis of tumour in vein were 97.0% (95% CI: 93.0-98.7) and 96.8% (95% CI: 92.1-98.7), respectively, without significant heterogeneity. A sROC curve was plotted, and the area under the receiver operating characteristic was 0.99 (95% CI: 0.98-1.00). Despite the presence of publication bias, sensitivity analysis did not show any change in sensitivity and specificity. Discussion: Our meta-analysis summarises the accuracy data from 12 studies, including >700 subjects. Contrast-enhanced ultrasound had excellent diagnostic accuracy with pooled sensitivity and specificity of 97.5% (95% CI: 93.5-99.1) and 98.2% (95% CI: 91.5-99.6), respectively, without any significant heterogeneity. Additionally, the pooled positive LR, negative LR and DOR were 54.6 (95% CI: 11.1-25.6), 0.02 (0.01-0.07) and 2186.8 (318.3-15022.2), respectively. A positive result increases the pretest probability of malignant PVT from 50% to 98%, whereas a negative result decreases it from 50% to 2%. Most of the studies included in our meta-analysis used identical techniques and 6-12-month follow-up scans to check for thrombus progression or regression. Our analysis showed no significant heterogeneity in the studies, and area under receiver operating characteristic curve (AUROC) with 95% CI was 1.00 (95% CI: 0.99-1.00). This critical meta-analysis thus propels CEUS to the forefront for differentiating benign from tumoural PVT and suggests routinely using CEUS in patients presenting with HCC and evidence of thrombus on greyscale ultrasound. Conclusion: Contrast-enhanced ultrasound is an effective diagnostic modality differentiation of benign and malignant PVT in patients with HCC and can be an alternative modality to CT or MRI. Further studies are required to study the role of CEUS as initial diagnostic modality for the characterisation of PVT in HCC.

BACKGROUND: Common bile duct (CBD) stones are known to complicate 10-15% of gallstone diseases. Endoscopic retrograde cholangiopancreatography (ERCP) is the therapeutic modality of choice for bile duct clearance in CBD stones but may fail to achieve stone clearance. This prospective study was done to identify the predictors of failure of CBD clearance with ERCP. OBJECTIVE: This prospective study was done to identify the predictors of failure of CBD clearance with ERCP. METHODS: All consecutive patients with bile duct stones undergoing ERCP at a tertiary care center were prospectively included from October 2020 to October 2021. The study's primary outcome was to identify and analyze factors that could predict the failure of complete CBD clearance. RESULTS: A total of 120 patients (50.8% males, median age: 53.5 years) were included in the final analysis. Successful clearance of CBD stones during the index procedure was achieved in 70% of patients. At a cut-off stone diameter of >10.5 mm and CBD diameter of >12.5 mm, the AUC was 0.890 and 0.884, respectively, to predict failed clearance of CBD. On multivariate analysis, stone diameter ≥15 mm [odds ratio (OR) 16.97, 95% confidence interval (CI): 1.629-176.785], location of stones in hepatic ducts (OR 7.74, 95%CI: 2.041-29.332), presence of stricture distal to stone (OR 6.99, 95%CI: 1.402-34.726) and impacted stone (OR 21.61, 95%CI: 1.84-253.058) were independent predictors of failed bile duct clearance. CONCLUSION: Stone size and location are independent predictors of failed bile duct clearance. The endoscopist should consider these factors while subjecting a patient to biliary ductal clearance to plan additional intervention. BACKGROUND: ⢠Failure to clear bile duct stones in the index ERCP can be seen in 15-20% of cases, and identifying the factors associated with failure is important. BACKGROUND: ⢠A prospective analysis was conducted to identify and analyze the factors that could predict the failure of complete CBD clearance. BACKGROUND: ⢠The present study reported a successful clearance of CBD stones during the index procedure in only 70% of patients. BACKGROUND: ⢠A stone diameter ≥15 mm, location of stones in hepatic ducts, presence of stricture distal to stone, and impacted stone were independent predictors of failed bile duct clearance.
