The role of ultrasound in diagnosis of obstructive Jaundice causes in Sudanese population

Abstract

This study was done to assess the role of ultrasound in diagnosis ofobstructive jaundicecauses. The study took place in different Khartoum clinical centers and hospitals in the period between Jan 2010 -March 2011.A total of 102 patients were examined using ultrasound(U/S), 3.5 MHz probe, Fukuda, Toshiba, Sheimadzu and Aloka Machine. The population of the study(jaundiced patients)had been selected by the technique of non-probability sampling and full history was taken.The causes of obstructive jaundice were detected as stone 19%., mass 51%,Sensitivity of ultrasound in determining the level of obstruction was 96% and extra hepatic obstruction was 67%. The prevalence ofobstructive jaundice was found to behigher in females (58%) than male (42%).Ascites and liver cirrhosis were found in 24% of the patients, hepatitis and hepatomegaly represent 33%.The study confirmed that obstructive jaundice represent 89.2% of the patients and non-obstructive jaundice was 10.8%.The study recommended to measure bile duct, liver size, portal vein, spleen and compare the liver echo texture with the adjacent organs .Scanning should be performedfor liver metastasis and also detect stone in the common bile duct.

Sonographic Evaluation of Obstructive Jaundice

“…In this study, it is observed that obstructive jaundice involves female more than male (65% vs. 35%) of our study sample. This result is consistent with a study conducted by Gameradin et al [9] who reports that female is more frequent affected with obstructive jaundice than males (58% vs. 42%). Another study confirms that the frequency of obstructive jaundice is higher among female population, and the most frequent causes of obstructive jaundice are gall stones (54.1% of patients) [10].…”

“…The age group of 66 -80 years old is the most affected group (64%). This result is consistent with Gameradin et al [9] who stated that the most affected groups were 45 -75 and 75 -95 years old respectively. Another study [11] reveals the range age between 60 -70 years old is the most involved and this is also in agreement with our finding.…”

Role of ultrasonography in evaluation of obstructive jaundice

“…Females predominated in our study similar to findings of other studies 5,7 . Females are frequently exposed to the drugs like contraceptive pills which lead to gallbladder stone and they are also exposed to excess hormones during recurrent pregnancies which might favor gall stone formation.…”

Role of Magnetic Resonance Cholangiopancreatography in Cases of Obstructive Jaundice in Correlation with Ultrasonography

“…In our study, there were a total of 58 females and 42 males showing female preponderance. This result is consistent with a study conducted by Gameraddin et al 10 who reported that females are more frequently affected Out of all studied patients with obstructive jaundice, 56 had malignant causes while 44 had benign causes; these results are consistent with those of Sharma and Ahuja, 11 who in their study had observed 73.3% patients had malignant cause, while 24.7% had benign cause. Similar results were shown by Moghimi et al 12 and Huang et al 13 It is also observed that benign causes are more frequently seen in females while malignancy is predominantly seen in elderly men; this finding was explained by Saluja et al 14 Siddique et al 15 and Park et al stated that presence of gall stones attributed to cholesterol stones are presumed to be related to metabolic disorders, which are more commonly seen in women, and malignancy predominates in males due to their habits of alcohol abuse and tobacco chewing.…”
