E-DUS combines endoscopy and duplex ultrasound to obtain detailed images beyond the innermost lining of the digestive tract. The procedure was performed with a Hitachi Aloka ProSound F75 and an Olympus GF-UCT180 curved linear array ultrasonic videoscope (180° ultrasound field of view). All E-DUS examinations were performed by the same experienced endoscopist (KÅ) at the Endoscopy Laboratory of the Department of Gastroenterology, Oslo University Hospital. Standards for E-DUS procedure were followed.22 (link),23 (link) All patients were in at least 6 hours of fasting state before the examination. All procedures were performed under conscious sedation with midazolam (mean 3.35 mg) and alfentanil (mean 0.77 μg). SaO2 was kept above 95% during the procedure. The patients were carefully monitored for any hemodynamic changes. The videoscope was placed in the upper part of the stomach along the lesser curvature and a longitudinal view of the aorta was obtained to identify the origin of the CA and SMA. None of the patients developed complications related to the endoscopy.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
