title: Laparoscopic radical right hemicolectomy for cecal cancer and middle colic artery aneurysm.
abstract: BACKGROUND
  Middle colic artery (MCA) aneurysms are very rare and exclusively reported with symptoms or rupture. We report successful laparoscopic elective surgery for both cecal cancer and MCA aneurysm in an 87-year-old man who presented with bloody stools.
  
  
  METHODS
  Diagnostic colonoscopy revealed a cecal tumor 40 mm in diameter that was histologically confirmed as a well-differentiated adenocarcinoma. The three-phase dynamic computed tomography showed a cecal tumor without any metastasis and an MCA aneurysm 10 mm in diameter. Radical right hemicolectomy with D3 lymph node dissection that included the MCA aneurysm was performed. The postoperative course was uneventful, and the patient survived without recurrence.
  
  
  CONCLUSIONS
  Even though the present patient was very elderly, the postoperative course of laparoscopic radical surgery for both an MCA aneurysm and cecal cancer was uneventful with good short-term outcomes.
