Introduction Acute appendicitis is the most common reason for emergency abdominal surgery in the pediatric population. Ultrasound (US) is a widely used modality to diagnose acute appendicitis. The aim of this study was to evaluate the effectiveness of portal vein diameter and flow velocity in acute appendicitis diagnosis. Methods Portal vein diameter and flow velocity were measured in children who were referred to radiology with a clinical diagnosis of acute appendicitis. The largest appendix diameter and leukocyte count of the patients were recorded. A control group was created which consisted of healthy children, and their portal vein diameter and flow velocities were also measured. Results The median age of the population was 10 years (range, 3–17 years). Mean portal vein diameter was 7.53 ± 1.55 mm in the control group, 7.92 ± 1.88 mm in the other diagnosis group, and 8.76 ± 1.91 mm in the acute appendicitis group. Mean portal vein diameter was significantly higher in the acute appendicitis group (p = 0.001). Median portal vein flow velocity was 17 cm/s (10–29 cm/s) in the control group, 18.3 cm/s (8–27 cm/s) in the other diagnosis group, and 20.5 cm/s in the acute appendicitis group. Median portal vein flow velocity was significantly higher in the acute appendicitis group (p = 0.00). Conclusion Detecting an increase in portal vein diameter and/or flow velocity in equivocal cases may support other clinical signs associated with acute appendicitis. Portal vein diameter and flow velocity can serve as additional diagnostic markers in acute appendicitis cases.

Abstract Background Esophageal varices (EV) is the most common apprehensive complication of portal hypertension in patients with cirrhotic liver. Guidelines recommend Upper gastro-intestinal endoscopic screening for EV in patients with newly diagnosed chronic cirrhosis (Imperiale et al. in Hepatology 45(4):870–878, 2007). Yet, it is invasive, time consuming and costly. To avoid unnecessary endoscopy, some studies have suggested Doppler ultrasound examination as simple, and noninvasive tool in prediction and assessment of severity of EV (Agha et al. in Dig Dis Sci 54(3):654–660, 2009). Our study was to assess the role of different Doppler indices of portal vein, hepatic and splenic arteries as a noninvasive tool for prediction of esophageal varices in cirrhotic patients. Results This prospective case control study was conducted on 100 cirrhotic liver patients and 100 of healthy volunteers as control group. Patients were subjected to clinical examination, upper gastrointestinal tract endoscopy, abdominal ultrasonography with duplex Doppler evaluation of different portal Doppler hemodynamic indices were done for each patient. The results revealed that portal vein diameter, hepatic artery pulsatility index, portal hypertensive index, portal vein flow velocity, portal congestion index have high sensitivity for prediction of EV. However, Splenic artery resistance index, hepatic artery resistance index HARI, liver vascular index and platelet count/spleen diameter have less sensitivity for prediction of EV. Conclusion Measuring the portal hemodynamic indices can help physicians as noninvasive predictors of EV in cirrhotic patients to restrict the need for unnecessary endoscopic screening especially when endoscopic facilities are limited.

Background: Liver cirrhosis represent the end stage of fibrosis that destroy normal liver parenchyma and leads to serious complication as portal hypertension which result in esophageal varices (EV), EV bleeding leads to high mortality, so repeated upper endoscopy needed to control bleeding which is invasive procedure and of high risk of hazards as infection. Our Study Aimed: to evaluate the Gallbladder Wall Thickening (GBWT) as a non-invasive predictor of Esophageal Varices (EV) in cirrhotic patients. Methods: In this cross sectional study, we tested 120 cirrhotic patients at gastroenterology and hepatology unit, internal medicine department, Tanta university hospitals. They were divided into 60 cirrhotic patients with EV and 60 cirrhotic patients without EV. All patients were subjected to history taking,  physical examination, investigation (complete blood count, liver function tests, viral markers) ultrasound detecting (gall bladder wall thickness, portal vein diameter, portal vein flow velocity, portal cross sectional area and gall bladder fasting volume) upper gastrointestinal endoscopy to detect presence or absence of varices. Results: Significant correlation was observed between gall bladder wall thickness (GBWT) and portal hypertension, GBWT ranged from 2.5 to 7 mm in group 2 (cirrhotic patients with EV) and from 1.5 to 5 in group 1( cirrhotic patients without EV). There is significant difference between group 1 and group 2 as regard GBWT with (P value < 0.05), portal vein diameter (PVD) with (P value <0.05) and platelets counts with (P value <0.05). Conclusions: We recommend thatgall bladder wall thickness can be used as a non-invasive predictor of esophageal varices in cirrhotic patients.

Objective: To compare the efficacy of carvedilol and propranolol to prevent reoccurrence of esophageal variceal bleeding in patients with liver cirrhosis. Study Design: Place and Duration: Department of Gastroenterology and Hepatology, Ayub Teaching Hospital, Abbottabad, Pakistan for six months duration from 15th November 2020 to 15th May 2021. Methods: Total one hundred and forty patients of ages between 18-65 years were presented in this study. Patients detailed demographics age, sex, body mass index and Child-Turcotte-Pugh (CTP) class were recorded after taking written informed consent. Patients were equally (n=70) divided into two groups. Group A had 70 patients and received carvedilol while group B had 70 patients and received propranolol for 6 months. Reoccurrence ofesophageal variceal bleeding in cirrhotic patients among both groups were observed at 2nd, 4th and 6th months and patients pulse rate, arterial pressure and portal vein flow were recorded at these time points. Complete data was analyzed by SPSS 26.0 version. Results: Mean age of the patients in group A was 40.38 ± 5.87 years with mean BMI 28.09 ± 7.33 kg/m2 and in group B mean age was 39.43 ± 12.69 years with mean BMI 27.53 ± 8.84 kg/m2. In group A 45 (64.3%) patients were males and 25 (35.7%) were female patients while in group B 50 (71.43%) were male patients and 20 (28.7%) patients were females. We found that there was no statistically significant difference observed among both groups regarding these demographic variables. Reoccurrence of bleeding observed in group A was significantly lower (among 20 (28.6%) cases) as compared to group B (among 36 (51.43%) cases). Pulse rate, mean arterial pressure and portal vein flow was found lower in the carvedilol group as compared to propanol group with p value < 0.05 upon follow up at2,4 and 6 months. Conclusion: We found in this study that the drug carvedilol was more effective and safe to prevent reoccurrence of esophageal variceal bleeding in cirrhotic patients as compared to propanol.

AbstractIntroduction: Portal hypertension results from increased resistance to the portal blood flow. The ultrasound represents a noninvasive tool for assessing the structural and hemodynamic abnormalities in this condition.Objectives: The assessment of the hemodynamic blood flow of the liver and spleen by using Doppler ultrasound in patients with portal hypertension compared with healthy subjects and to identify correlations with the severity of liver cirrhosis and esophageal varices.Materials and Method: This study included 50 patients with liver cirrhosis and 20 healthy subjects as controls. Different correlations were carried out between hemodynamic variables obtained from the Doppler examination and the severity of cirrhosis as assessed by the Child score and the degree of esophageal varices at endoscopy.Results: The portal vein diameter was larger in cirrhotic patients compared with the control group. The mean portal vein velocity and the blood flow were significantly lower in advanced forms of liver cirrhosis. The portal vein congestion index, the pulsatility and resistivity indexes of the hepatic artery were significantly increased in patients with CHILD B and C cirrhosis compared with the control group and patients in CHILD class A. There were no statistically significant differences between the pulsatility and resistivity indexes of the splenic artery in patients with cirrhosis. The liver vascular index was significantly lower in patients with advanced cirrhosis.Conclusions: The ultrasound is a valuable noninvasive tool for cirrhotic patients with portal hypertension. However, it is not sufficiently accurate in differentiating between different classes of cirrhosis or degrees of esophageal varices.

 Introduction: Upper Gastro-intestinal endoscopy is considered the best screening tool for varices in cirrhotic patients. It is still an expensive, invasive tool, has poor compliance and not routinely available in every hospitals in Nepal. This study was undertaken to establish the role of portal vein diameter and spleen size by ultrasonography in predicting gastro-esophageal varices.Method: One hundred and fifty patients with clinical features, laboratory and sonological findings suggestive of cirrhosis of liver and endoscopic evidence of portal hypertension were included in the study. Ultrasonography assessments of portal vein diameter and spleen size alongside endoscopy for detection of varices were done.Result: Average portal vein diameter of patients without gastro-esophageal varices was 10.800 ± 1.1402 mm, while it was 13.731 ± 1.061mm in patients with varices(p<0.001). Average spleen size of patients without varices was 12.67 ± 2.35 cm and with varices was 15.367 ± 1.210 cm (p < 0.001). There was 92.72 % sensitivity and 90 % specificity for prediction for presence of esophageal varices when the cutoff value for portal vein diameter was 12.25 mm. There was 94.5 % sensitivity and 75 % specificity for prediction for presence of esophageal varices when the cutoff value for spleen size was 13.9 cm.Conclusion: Ultrasonography of portal vein diameter and spleen size is a reliable non invasive tool in predicting the presence of gastro-esophageal varices in patients with liver cirrhosis. With increase in portal vein diameter and spleen size, risk of formation of gastro-esophageal varices also increases and positive correlations exist between them. Nepalese Journal of Radiology, VOL 4 No. 2 ISSUE 7 July-December, 2014: 6-14
