A Case of Laparoscopic Right Hemicolectomy for Ascending Colon Cancer with Severe Neutropenia of Aplastic Anemia

Abstract

A 68-year-old woman with progressive anemia was diagnosed with ascending colon cancer with stenosis. Pre-operative survey indicated that she had pancytopenia. A detailed examination revealed that she suffered from aplastic anemia. Laboratory tests showed severe pancytopenia as follows : white blood cell count 1,010/μl (neutrophil count, 19/μl), Hb 6.0 g/dl, and platelet count 8.0×10⁴/μl. Since it takes at least several months to treat aplastic anemia, mortal complications due to the cancer may occur during that period. Therefore, laparoscopic right hemicolectomy and ileostomy were performed first. The surgery was successfully executed and she had no complications, such as surgical site infection or bleeding after the surgery that might be caused by aplastic anemia. The present case is reported along with a review of the relevant literature.
