Cirrhosis leads to portal hypertension and development of gastroesophageal varices, which are the most common cause for bleeding in cirrhosis and a major cause of death. The American Association for the Study of Liver Disease (AASLD) recommends screening endoscopy every 2 years to evaluate for gastroesophageal varices, and annual surveillance for those with small varices on endoscopy. Unfortunately, endoscopy is costly, requires sedation, is poorly tolerated, is subject to high inter-observer variability, and is associated with risks that include bleeding, esophageal injury and aspiration. Noninvasive methods for evaluation of gastroesophageal varices are needed. CT is noninvasive, rapid, less expensive than endoscopy, requires no sedation, provides a quantitative measure of the size of the varices, and allows for assessment of para-esophageal varices, varices in other body locations, ascites, other signs of portal hypertension, patency of liver vasculature, and detection, diagnosis and staging of hepatocellular carcinoma. Single-Energy CT (SECT) has relatively high accuracy in prospective studies for detection of any and large varices but is associated with suboptimal contrast opacification of gastroesophageal varices. Dual-Energy CT with the GE scanners with GSI Xtream (DECT) improves the contrast-to-noise ratio by 60% compared to SECT and is currently standard of care at UAB for evaluation of cirrhosis. The primary objective of this study is to determine the accuracy of DECT for detecting any varices and high-risk varices. The study hypothesis is that the accuracy (AUROC) of DECT will be >0.90 and >0.95 for detecting any and high-risk varices in a prospective pilot study (N=50) that uses endoscopy as the reference standard. This will be a single-center pilot observational prospective IRB-approved study. A total of 50 adult patients presenting to UAB Endoscopy for surveillance endoscopy to detect and grade gastroesophageal varices will be enrolled.
Results of recent systematic reviews suggest favorable results of embolization for the treatment of Pelvic Congestion Syndrome (PCS) compared with pre-procedure symptoms for several outcomes, including pain reduction, overall patient satisfaction, and technical feasibility. Reported complication rates appears relatively low. Pelvic vein embolization is a relatively new technology and the results may provide background for an evidence based decision to offer embolization of pelvic varicosities for women with PCS in Norway.
A pilot randomised controlled trial looking at the setting up of a one stop vein clinic for the treatment of varicose veins and assessing the quality-adjusted life years at 3 months of patients This will be a pilot study which is designed to provide us with enough information for a potentially larger multicentre randomised controlled study.
The study will test the hypothesis that patients anesthetized with propofol suffer less postoperative pain than those anesthetized with sevoflurane.
This trial was designed as a prospective, multi-center, randomized clinical trial of the FDA-cleared Vari-Lase Bright Tip Fiber compared to commercially available standard bare-tip laser fiber (control) to demonstrate the safety and effectiveness of laser ablation for the treatment of varicose veins associated with reflux within the great saphenous vein (GSV) and to provide additional data concerning patient satisfaction. Within this evaluation, subject limbs were randomized to one of two (2) treatment groups utilizing a 1:1 randomization ratio. If a subject required treatment of only one limb, that limb was randomized to a treatment group. If a subject required treatment of two limbs, the first limb was randomly assigned treatment and the second limb was assigned the other treatment (the opposite treatment of the other limb). The data was analyzed by treated limb (versus treated subject).All study data were analyzed under the principles of intent-to-treat, in which data are analyzed according to the assigned randomized group regardless of the treatment actually delivered. Subjects were followed at one week, one month, and six months.
