Ultrasonografi ile Splenomegali Tespiti: Tek Ölçüm mü Yoksa Hacim Hesabı Mı?

Giriş: Splenomegali birçok hastalık için önemli bir bulgudur. Dalak uzun ekseni on üç cm'den büyük ise araştırılır ve bazen invaziv incelemeler yapılır. Dalak büyüklüğü yaşa, cinsiyete, vücut kitle indeksine ve ırksal farklılıklara bağlı olarak değişebilir. Bu çalışmanın amacı, sağlıklı bireylerde dalak boyutları ve hacmi arasındaki ilişkiyi araştırmaktır. Gereç ve yöntem: Bilinen bir hastalığı olmayan ve gastroenteroloji polikliniğine başvuran, ultrasonografi ile temel değerlendirme yapılan hastalar çalışmaya dâhil edildi. Ultrasonografik ölçümler tek bir uzman radyolog tarafından yapıldı. Dalak hacmi, prolate elipsoid formülüyle hesaplandı (uzunluk × genişlik × derinlik × 0.523). Bulgular: Çalışmaya toplam 245 hasta (146 kadın, 99 erkek) dâhil edildi. Dalak hacmi korelasyon analizinde boy (r=0.505; p<0.05), ağırlık (r=0.367; p<0.00), bel çevresi (r=0.208; p<0.05) ve vücut yüzey alanı ile pozitif korelasyon (r =0.269; p<0.05) ve yaş ile negatif korelasyon (r=-0.269; p<0.05) gösterdi. lojistik regresyon analizinde maksimal uzunluğun ana belirleyicilerinin vücut yüzey alanı, yaş ve ağırlık olduğu bulundu. Sonuç: Dalak hacmi ölçümleri çoğunlukla dalak genişliği ile ilişkilidir. Dalak hacmi yaşla birlikte azalır ve vücut ağırlığı ve vücut yüzey alanı ile ilişkilidir. Dalak hacminin ölçülmesi, splenomegalinin saptanmasında yardımcı olabilir.

Evaluation of Spleen with Ultrasonography: Single Measurement or Volume Detection?

Introduction Splenomegaly is an important finding for many diseases. Splenic long axis greater than eleven cm are investigated and sometimes invasive examinations are performed. Splenic size may differ depending on the age, gender, body mass index and racial differences. The aim of this study is to investigate the relationship between splenic dimensions and volume in the patients attended to gastroenterology outpatient clinics Material and Method Patients without a known disease and applied to gastroenterology outpatient clinic needed basic evaluation with ultrasonography are included in the study. A single skilled radiologist performed ultrasonographic measurements. Splenic volume is calculated by prolate ellipsoid formula (length × width × depth × 0.523). Results/Findings A total of 245 patients (146 female, 99 male) were enrolled in the study. In correlation analysis of spleen volume was positively correlated with height (r=0.505; p<0.05), weight (r=0.367; p<0.00), waist circumference(r=0.208; p<0.05), and body surface area (r=0.269; p<0.05) and negatively correlated with age (r=-0.269; p<0.05). ın logistic regression analysis, the main determinants of maximal length were found to be body surface area (BSA), age, and weight. Conclusion Splenic volume measurements are the mostly correlated with width of spleen. Splenic volume decreases with age and correlated with BSA and weight. Measuring splenic volume may be helpful in detecting splenomegaly.
