Abstract

Introduction: A detailed knowledge on morphometric variations of the spleen is of great value in diagnosing splenomegaly clinically, radiologically and for surgical procedures.

 

Objectives: This study was undertaken to establish splenic morphometry in a group of Sri Lankan adults.

 

Methodology: Splenic morphology was noted and maximum length, thickness, width were recorded (n=30) using a vernier caliper (Tricebrand) with minimum measurement of 0.001cm. The weight was measured with a manual triple beam balance (up to 0.1g). Splenic index (width x length x thickness) and splenic volume (0.524 x splenic index) were calculated. Cadavers with history of haemopoetic or reticular endothelial disorders, ruptured, grossly adhered spleens were excluded from the study. Results were expressed as mean ± SD.

 

Results: Out of the total spleens, 43.3% were semilunar, 33.3% wedge, 10% oval, 3.3% tetrahedral, 6.6% polygonal wedge shaped and 3.3% single lobed liver shaped. Notches were absent in 16.67% and when notches are present they are exclusively in the superior border. Single notch was present in 26.7%. Out of single notches, 30% were posterior pole notches. More than one notch was present in 46.7% and the 81.8% of those were in the anterior pole. Mean length, width and thickness were 8.06cm ± 1.66, 7.65cm ± 1.05 and 5.33cm ± 0.89 respectively. Splenic index was 174.67. Splenic volume and weight were 91.52 cm3and 80.13g± 35.84 respectively.

 

Conclusion: This pilot study reveals that the splenic morphology is in par with other populations and bipolar length of the spleen has strong positive correlation with the volume. Large scale study is recommended to establish population specific data base.
