[A Case Involved Successful Treatment of Cecum Colon Cancer with Idiopathic Thrombocytopenic Purpura(ITP)by Laparoscopic Resection].

A 91-year-old woman visited a local hospital with the chief complaint of bloody stool. The patient was noted that her platelet count is 1,000/μL, so she was referred to our hospital. Also after admission, she had bloody stool continuously. Then lower gastrointestinal endoscopy was done and it indicated that the reason for these symptoms is cecum colon cancer (cT3N0M0). We decided to perform an operation. Before the operation, in order to improve her platelet count to 100,000/μL high dose intravenous immunoglobulin, steroid therapy and platelet transfusion had done. The operation is laparoscopic ileocecal resection and the amount of bleeding is 10 g. The postoperative course was uneventful, and her platelet count became within normal range by platelet transfusion for 4 days. Until latest follow-up she has neither recurrence of the cancer nor thrombocytopenia. This case suggests that appropriate treatments make it impossible laparoscopic surgery for cecum colon cancer with ITP perform safety and resection for cancers may contribute to improve ITP.
