Aim Splenectomy is a well‐known procedure to improve thrombocytopenia and liver function in patients with liver cirrhosis (LC). However, the effect of splenectomy on liver regeneration remains unclear. The aim of this study is to investigate the effect of splenectomy on liver regeneration. Methods Twenty patients with LC who underwent splenectomy were included in this study. Liver and splenic volumes were measured by a 3‐D simulation imaging system. Liver volume (LV) and clinicopathological data were compared before and 6 months after splenectomy. Thereafter, patients were divided into two groups: the elevated LV group and the reduced LV group. Patient characteristics were compared between the two groups. Results Postoperative LV was increased in 14 patients compared with the preoperative state. Thrombocytopenia, leukopenia, total bilirubin and prothrombin time were improved after splenectomy. In the elevated LV group, four patients exhibited improved Child–Pugh grades after splenectomy, whereas no patients demonstrated improvement in the reduced LV group. The elevated LV group exhibited high albumin level, good indocyanine green retention rate at 15 min and large splenic volume compared with the same measurements in the decreased group. Patients with larger spleen volumes and higher albumin values before splenectomy showed increased rates of LV after splenectomy. Conclusion Splenectomy for patients with LC improved pancytopenia and liver function. Especially, in patients with large spleen and high albumin levels, considerable increases in LV and improved liver function were observed.
