Aim: In this study, we aimed to provide information about transient elastography, a noninvasive method that shows liver steatosis and fibrosis, and to review diagnostic accuracy studies in the literature.

Background: Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver diseases. It has a wide clinical spectrum, ranging from asymptomatic steatosis to cirrhosis with complications that can lead to mortality. Although its frequency varies geographically, it is believed that one out of every four people in the world has NAFLD. Recently, the number of studies about the noninvasive diagnosis of NAFLD and liver fibrosis is increasing. Vibration-controlled transient elastography (VCTE) is a method used for about two decades and provides important information in determining steatosis and fibrosis in the liver.

Review results: Area under curve (AUC) levels for ≥S1 are between 0.8 and 0.95 in studies showing the accuracy of the CAP score in detecting steatosis. Sensitivity is between 68 and 87% and specificity is 74 and 91%. AUC levels for steatosis ≥S2 range from 0.73 to 0.88. Sensitivity is between 77 and 85% and specificity is 59 and 81%. For detecting ≥S3, AUC levels were 0.69 to 0.94 and the sensitivity and specificity were 71 to 88%, and 58 to 89%, respectively. In studies, evaluating the effectiveness of elastography in determining the level of fibrosis in patients with NAFLD: AUC was between 0.79 and 0.87, sensitivity was 62 and 94%, and specificity was 61 and 100% for F ≥2. Area under curve was 0.76 to 0.98, sensitivity was 65 to 100% and specificity was 75 to 97% for ≥F3. Area under curve was ranged from 0.91 to 0.99 and sensitivity was 78 to 100% and specificity was 76 to 98% for ≥F4. The studies about the comparison of FibroScan and novel transient elastography device (FibroTouch) reported that results are correlated (r = 0.5-0.6) and the AUC of FibroTouch to detect fibrosis is nearly 0.8.

Conclusion: AUROC in studies are mostly above 0.80 in detecting steatosis and detecting the presence of fibrosis in patients diagnosed with NAFLD indicates the reliability of the data obtained. Transient elastography is suggested by the international guidelines for diagnosing NAFLD, especially the decision of biopsy. FibroTouch was found correlated with FibroScan but further studies are necessary to indicate that FibroTouch can be used instead of FibroScan.

Nonalcoholic fatty liver disease (NAFLD), in a few decades, is expected to be the commonest cause of end-stage liver disease and liver cancer surpassing all other etiologies. Urbanization and modern lifestyle have led to global epidemic of NAFLD with alarming prevalence rates across the globe. Its multisystemic involvement manifests as metabolic syndrome, diabetes, cardiovascular disease, end-stage liver disease, and hepatic and extrahepatic malignancies. The absence of promising therapy for halting disease progression in NAFLD is a challenge that is not only limited to liver disease but also other organs involved. It is unrealistic to expect any significant impact of pharmacotherapies in overall survival of NAFLD patients, given that the morbidity and mortality in these patients are contributed by conditions other than that of liver. Liver-centric approach in managing NAFLD will be futile unless the problem is dealt in a holistic manner. Lifestyle modifications have been repeatedly appraised in prevention and treatment of various diseases linked to metabolic syndrome including NAFLD. Despite being inexpensive and highly efficacious in prevention and treatment of different manifestations of NAFLD, lifestyle intervention often fails to gather sufficient interest among patients and physicians alike. This review intends to highlight pleiotropic nature of this disease, limitations of currently available pharmacotherapies and evidence that emphasizing lifestyle intervention is the only way to holistically deal in patients with NAFLD.

Introduction: Post-endoscopic retrograde cholangiopancreatography (ERCP) cholangitis (PEC) is associated with increased morbidity and mortality in patients ERCP. The aim of the present study was to analyze the predictors of PEC and to formulate a predictive model for early diagnosis and management.

Materials and methods: It was a cross-sectional study that was carried out at the Sindh Institute of Urology and Transplantation from September 2019 to June 2021. All patients aged between 18 and 75 years and undergoing ERCP due to obstructive jaundice were included. Patients with altered biliary anatomy, history of hepatobiliary surgery, and concurrent sepsis were excluded. Endoscopic retrograde cholangiopancreatography intervention was performed by an expert gastroenterologist. Laboratory parameters (total leukocyte count, total bilirubin, alanine transaminase) and patient temperature were checked on admission, at 12 hours, 24 hours, and 36 hours after ERCP to document PEC.

Results: A total of 349 patients were included in the study. Among them, 176 (50.4%) patients were males. Common bile duct (CBD) stricture was the most common indication of ERCP seen in 148 (42.4%) patients followed by CBD stone and cholangiocarcinoma in 108 (30.9%) and 48 (13.8%) patients, respectively. The most common presenting complaint was jaundice noted in 300 (86%) patients followed by right hypochondrial pain in 280 (80.2%) and weight loss in 194 (55.6%) patients, respectively. Post-ERCP cholangitis developed in 251 (71.9%) patients. On univariate analysis, age >50 years, female gender, right hypochondrial pain, fever, bilirubin >5 mg/dL on admission, CBD stricture on ERCP, TLC of >10,000 cells/L at 12 hours, 24 hours, and 36 hours post-ERCP and rise in ALT >50 IU 24 and 48 hours post-ERCP were significantly associated with PEC. While on multivariate analysis, female gender, bilirubin >5 mg/dL on admission, CBD stricture on ERCP, post-ERCP fever, and rise in TLC of >10000 cells/L at 24 hours post-ERCP were independently associated with PEC. HinCh score was formulated and was found to be significantly associated with the presence of cholangitis. Area under the receiver operating characteristics (AUROC) of HinCh score was 0.74 and at cutoff of ≥4, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of HinCh were 81.67%, 59.18%, 83.67%, and 55.71%, respectively with a diagnostic accuracy of 75.36%.

Conclusion: The performance of HinCh score in predicting PEC was accurate in 86% of the patients. However, further studies are needed to validate the score.

Background: Laparoscopic cholecystectomy is a common operation worldwide, with low mortality (0.01%) and morbidity (2-8%). It has been reported 2.9 to 3.2% of elective laparoscopic cholecystectomies are converted to open surgery. Converted cases are associated with increased complications rates.

Method: Two thousand and seventy-five patients, 82.8% females and 17.2% males who underwent elective laparoscopic cholecystectomy in our hospital, between March 1, 2016, and February 28, 2018, were prospectively collected in a database. Pearson's Chi-squared and Fisher's exact tests were used to determine significance, with p <0.05 deemed statistically significant. We analyzed seven risk factors associated with conversion to open surgery; age, gender, body mass index (BMI), previous abdominal surgeries, the presence of contracted gallbladder, Mirizzi syndrome, or choledocholithiasis. Laparoscopic cholecystectomy was performed using a 3-port technique (73%) and a 4-port technique (27%).

Results: Finding associated "strong" factors to conversion: male patients, >60-years-old, previous upper abdominal surgery, contracted gallbladder, Mirizzi syndrome or choledocholithiasis. The presence of a higher or lower BMI did not influence the rate of conversion. The most impact association were males over 60 years, and males with an earlier upper abdominal surgery.

Conclusion: Laparoscopic cholecystectomy is the gold standard for gallstones and gallbladder disease; however, inflammation, adhesions, and anatomic difficulty continue to challenge the use and safety of this approach in a small number of patients. This study identifies predictors of choice for open cholecystectomy. In view of the raised morbidity and mortality associated with open cholecystectomy, distinguishing these predictors will serve to decrease the rate of conversion and address these factors preoperatively.

Introduction: Gallbladder cancer (GBC) is the most common malignant biliary tract tumor with the shortest survival from the time of diagnosis. This poor prognosis is due to the destructive biologic behavior of GBC, lack of sensitive screening tests for early detection, and vague nature of first presentation. Here in this study, we will evaluate the baseline characteristics of the patients presenting with gallbladder carcinoma in our population.

Materials and methods: This retrospective study was conducted in the Department of Gastroenterology at Sindh Institute of Urology and Transplantation (SIUT), Karachi. Patient data were compiled and composed from the in-patient health records, radiology, and operational records. Those patients with suspicion of GBC, but negative at histology, or patients having inconclusive radiologic findings, were excluded. Baseline characteristics were recorded. Results were presented as means ± SD for quantitative data or as numbers with percentages for qualitative data. Continuous variables were analyzed using the Student's t-test, while categorical variables were analyzed using the Chi-square test. A p-value of <0.05 was considered statistically significant.

Results: A total of 162 patients were included in our study. Among them, 101 (62.3%) were females. Hypertension was the most common comorbid illness noted in 29 (17.9%) patients while 91 (56.2%) patients had no concurrent comorbidities. Most common risk factor for carcinoma of gallbladder was gallstones seen in 106 (65.1%) patients. The most common presenting complaint was combination of obstructive jaundice, weight loss with right hypochondrial pain seen in 66 (40.7%) patients. On CT abdomen, direct liver infiltration without lymphovascular invasion was noted in 77 (47.5%) patients followed by liver infiltration along with lymphovascular invasion in 26 (16%) patients and distant metastasis in 24 (14.8%) patients. On gallbladder (GB) mass biopsy, 58 (35.8%) patients had well-differentiated, 46 (28.4%) had moderately differentiated, while 33 (20.4%) had poorly differentiated adenocarcinoma. Of 162 patients, 103 (63.6%) patients underwent endoscopic retrograde cholangiopancreatography (ERCP). The most common finding on ERCP was proximal common bile duct (CBD) stricture with intrahepatic biliary system dilatation which was noted in 95 (58.6%) patients. Percutaneous transhepatic cholangiography (PTC) was performed only in 9 (5.6%) patients. Seventeen (10.5%) patients were managed by simple cholecystectomy, 39 (24.1%) patients underwent extended cholecystectomy, 14 (8.6%) patients underwent chemotherapy, while 102 (56.8%) patients were given palliative management. When followed for 1 year, 101 (62.3%) patients died within 6 months.

Conclusion: The baseline characteristics, biopsy findings, modes of treatment, and rates of 1 year mortality were studied in patients with

Barrett's esophagus, which results from chronic gastroesophageal reflux disease, is a known precursor to dysplasia and ultimately esophageal adenocarcinoma. Mixed neuroendocrine - nonneuroendocrine neoplasm (MiNEN) is a rare and heterogenous group of neoplasm with aggressive clinical behavior in general. There have been rare reports of MiNEN arising in Barrett's esophagus, and its pathogenesis remains unclear. Surgical resection with lymph node dissection remains the most effective treatment of MiNEN of the esophagus to date, although the evidence on its optimal treatment is scant.

Aim: This study aimed to assess the demographic details of coronavirus disease-2019 (COVID-19) patients, their comorbid conditions, preexisting illnesses such as tuberculosis (TB), the prevalence of gastrointestinal (GI) symptoms, duration of GI symptoms, gender-wise distribution of GI symptoms, age-wise distribution of GI symptoms, lab investigation, and computed tomography (CT) scanning was done to record the grading.

Materials and methods: In total, 956 COVID-19 patients admitted to an isolation ward of a tertiary care center were screened for 3 months. Patients were confirmed positive for SARS-CoV-2 virus by real-time polymerase chain reaction (RT-PCR) test with a throat swab. Patient's age, demographic details, preexisting illness, and GI symptoms such as fever, impairment of appetite, loss of taste, loss of smell, hiccups, nausea, vomiting, diarrhea, abdominal pain, symptom's duration, history of chronic drug intake, biological markers, CT scanning, and comorbidities were recorded. Based on the provided protocol, standard care management was given to the admitted COVID-19 patients.Statistical analysis was performed using SPSS version 20.0. Frequencies with percentages, median (min, max), Chi-square test, and Mann-Whitney U test were used to test the statistical significance, and a p-value of <0.05 was considered statistically significant.

Results: In our prospective study of 956 COVID-19 hospitalized patients, details were analyzed and the results are: the median age was 45 years, 70% of male, 60% were above 35 years, comorbidities like diabetes present in 42%, hypertension in 36%, asthma in 8%, cardiovascular diseases (CVD) in 5%, and history of chronic drug intake in 21%.Among 956 COVID-19 patients, GI symptoms were loss of smell (29.2%), loss of taste (26.4%) for 3 days; nausea (10%), vomiting (7.1%), abdominal pain (12.7%), and fever (42.5%) were observed for 2 days among the 36-45 years of age-group; and the loss of appetite (19%) for 3 days among the age-group of 46-55 years.The loss of appetite (23.7 vs 16.9%) (p= 0.014), taste (32.4 vs 23.8%) (p = 0.005), nausea (14.6 vs 8.2%) (p = 0.003), and vomiting (10.8 vs 5.5%) (p = 0.004) were higher in females than in males. No gender difference was observed in loss of smell (p = 0.057), abdominal pain (12 vs 14.3%) (p = 0.491), hiccups (4 vs 2.1%) (p = 0.132), and fever (41.3 vs 45.3%) (p = 0.329).Females had significantly higher levels of C-reactive protein (CRP) than males (6.1 vs 3.8) (p = 0.002). No gender difference was observed in neutrophil/lymphocyte ratio (NLR) (p = 0.772), ferritin, and lactate dehydrogenase (LDH). CT-grade IV was higher in males than in females (1.7 vs 1.5%), but the rest of the CT grades were higher in females than in males.

Conclusion: In conclusion, GI symptoms are the onset of symptoms tha

Aim: To evaluate the efficacy of intravascular ultrasound (IVUS) in transjugular intrahepatic portosystemic shunt (TIPS) revision associated with phlebography and invasive pressure measurement in patients with clinical or radiological signs of TIPS malfunction.

Background: Four patients underwent TIPS revision between February and August 2021. Right internal jugular vein access was achieved under ultrasonographic guidance, a catheter was advanced to achieve the Inferior Vena Cava (IVC) and afterward the Portal vein through the TIPS. Once the Portal vein was achieved, a phlebography was performed, followed by invasive pressure measurement and IVUS exam over the guidewire. Based on the combination of phlebography, invasive pressure measurement, and IVUS evaluations, TIPS dysfunction was treated either with angioplasty or stent apposition.

Case description: In all patients, we obtained the reduction of porto-systemic gradient. In three patients, angioplasty with a 10 mm diameter balloon catheter was performed. Anticoagulation therapy was added to one patient. In one patient, the Viatorr's proximal extremity in the suprahepatic vein wall was dislocated, so it was lengthened with a "Viabahn" covered stent. None of the patients developed hepatic encephalopathy after both TIPS placement and TIPS revision. No complications related to the procedure were observed during the follow-up. Clinical improvement in the immediate follow-up period was observed in all patients. In two patients, the abdominal ascites resolved. In another one, the abdominal pain disappeared, and a reduction of the longitudinal spleen diameter was recorded at 3 months follow-up.

Conclusion: The use of IVUS allowed us to correctly visualize the organic cause of TIPS malfunction and to obtain direct visualization of the results of endovascular treatment.

Background: Therapeutic plasma exchange (PLEX) removes toxins and different mediators from plasma in patients with acute-on-chronic liver failure (ACLF).

Aim: To observe the safety and outcome of PLEX in ACLF patients in Bangladesh.

Materials and methods: Twenty-eight patients with ACLF attending Bangabandhu Sheikh Mujib Medical University from September 2020 to May 2021 were enrolled in the study. The patients were given different treatment modalities and followed up for 3 months or up to death. The patients were divided into two groups, each containing 14 patients of ACLF. One group of 14 patients received standard medical therapy (SMT) for ACLF and the second group of 14 patients received SMT plus PLEX.

Results: At 90 days, a total of 13 patients (46.43%) survived, of them 8 (57.1%) belonged to PLEX group and 5 (35.7%) were from SMT group. Serum bilirubin and ALT declined significantly after 7 and 30 days but not after 90 days in PLEX group in comparison to SMT group (p <0.05) but other biochemical parameters were not significantly different (p >0.05) between these two groups. Significant (p <0.05) improvement of MELD, MELD-Na, and AARC scores was observed in each group from baseline to subsequent first, second, and third follow-up but no significant (p >0.05) difference was observed in between two groups. Binary logistic regression analysis found that bilirubin, MELD score, MELD-Na score, and AARC score were predictors of mortality.

Conclusion: The study presented here has shown that PLEX is safe in Bangladeshi in ACLF patients, but its efficacy remains to be checked in large-scale randomized trial or in combination therapy with other procedures in ACLF patients.
