Abstract

Objectives To investigate peripheral cytopenia in patients with splenomegaly due to hepatitis B-related cirrhotic portal hypertension (HBRCPH) by comparing blood cell counts from enlarged spleens with peripheral blood. Methods This prospective study involved patients undergoing splenectomy at the Nangfang Hospital from June 2013 to December 2015. Blood cell counts from peripheral blood were compared with those from splenic blood taken during splenectomies. Results Clinical data were available from 30 patients. White blood cell (WBC), red blood cell (RBC) and platelet counts were statistically significantly lower in peripheral blood compared with splenic blood. After splenectomy, peripheral blood cell counts increased significantly compared with pre-operative levels. Platelet and WBC counts in the lower spleen were significantly higher than those in the porta lienis (middle segment) and upper spleen. Conclusions In patients with splenomegaly due to HBRCPH, the counts of three blood cell lineages were significantly higher in the spleen than in peripheral blood. Splenectomy can aid the return of peripheral blood cell counts to normal levels. The most significant retention of platelets and WBCs occurred in the lower spleen which may be useful information for surgeons performing partial splenectomies.
