[Resection of Synchronous Liver Metastasis from Ascending Colon Cancer with Aplastic Anemia-A Case Report].

The aplastic anemia(AA)syndrome is characterized by pancytopenia and bone marrow hypoplasia. Although anemia, bleeding tendency, and susceptibility to infection are issues of concern during surgery, few reports have been published on the perioperative management, and management methods have not been established. A 77-year-old woman visited our hospital with chief complaints of melena and fatigability. Marked pancytopenia was observed at the first visit. After a detailed examination, she was diagnosed with ascending colon cancer accompanied by AA and solitary liver metastasis. As AA responded poorly to treatment, without improvement in pancytopenia, we decided to perform colectomy. The perioperative management, including blood transfusion and administration of a G-CSF preparation, was performed in collaboration with a hematologist, followed by right hemicolectomy and hepatic lateral segmentectomy. She was transferred to the department of hematology on hospital day 8 without complications. In conclusion, a highly invasive surgery, as in the present case, can be performed safely with an appropriate perioperative management even in cases complicated by AA.
