Sonographic Evaluation of Some Abdominal Organs in Sickle Cell Disease Patients in a Tertiary Health Institution in Northeastern Nigeria.

BACKGROUND

Sonographic evaluation of abdominal organs is an important work up in managing sickle cell disease (SCD) patients. This study aimed at evaluating abdominal organs by sonography among SCD patients.

METHODOLOGY

A cross-sectional study was carried out in Maiduguri, Nigeria from April 2014 to July 2015. Two hundred and fifty-two patients participated in the study, with 126 controls and 126 SCD patients. There were 131 (52%) males, and 121 (48%) females, with age range 3-38 years. Measurements were done using ultrasound machine with probe frequencies ranging from 1-4MHz and 4-9MHz in supine, right and left oblique positions for optimum visualization of the abdominal organs.

RESULTS

Participants within the age range of 10-15 years had the highest frequency with 88 (34.9%), followed by those within the age group of 17-23 years with 86 (34.1%), and the least were those within the age group of 30 years and above with 8 (3.2%). Hepatomegaly was found in 53 (75.7%), and increased echogenicity of the liver was found in 50 (94.3%) of the SCD patients, = 0.000. Gallstones were found in 45 (17.9%), gallbladder sludge was found in 51 (21.4%) and thickened gallbladder wall was found in 84 (33.3%) of the SCD patients, = 0.000. Autosplenectomy was found in 45 (17.9%), splenomegaly in 63 (24.9%), and calcified spleen in 18 (8.7%) of the SCD patients, = 0.000. Enlarged kidneys in SCD patients were found in 61 (98.4%) and 63 (98.4%) on the right and left kidneys, respectively. Shrunken kidneys were found in 5 (2.0%) and 4 (1.6%) of the SCD patients on the right and left kidneys, respectively, = 0.000.

CONCLUSION

Abdominal sonography in SCD patients revealed varied remarkable changes in the size, echotexture, intraluminal deposits and wall thickness in the liver, gallbladder, kidneys, and spleen.
