Evaluation of Caudate to Right Lobe Ratio of the Liver in Normal Sudanese Using Ultrasonography

Abstract

Caudate-right lobe ratio (C/RL) is a non-invasive method used in the assessment of liver size, usually in the setting of cirrhosis. This was a descriptive cross- sectional study that was carried out to evaluate the ratio between the caudate and right liver lobes among the normal Sudanese population at Omdurman teaching hospital and Alzaiem Alazhari ultrasonic clinic. This study was conducted from December 2016 to March 2017. To measure the length of acaudate liver lobe, to calculate the caudate to right lobe ratio(C/RL) , to correlate the result with the participant's age, weight, and gender ,and to establish a normal ratio in Sudanese. This study applied among 90 participants, who had no evidence of hepatic pathology. The data was collected using a data collection sheet which was classied and analyzed by using a statistical package for social science (SPSS). The study found that the caudate to right Lobe ratio in Sudanese ranged from 0.3 to 0.6, the maximum and minimum length of the caudate lobe obtained was (8cm and 3cm) respectively, while the maximum and minimum length of the right lobe obtained was (14cm and 10 cm) respectively, the study found that there was no signicant correlation between participant age and caudate to right lobes ratio The study concluded that ultrasound is an easy, available, less expensive, non-invasive, and safe tool for assessing the liver. The study recommended that the use of ultrasound in investigating the liver and oor be open for other investigators to participate.
