title: Pure laparoscopic sigmoidectomy.
abstract: OBJECTIVE
  Laparoscopic colectomy is performed widely all around the world, and some institutions perform more laparoscopic operations than conventional open operations. Although this surgical technique is performed recently, an operative wound formed during the surgery is large and is not easily remedied. Thus, a certain sized skin incision is required to remove the resected colon. Here, we report the case of a pure laparoscopic sigmoidectomy, which involves transanal specimen extraction.
  
  
  METHODS
  We present a case characterized by a large adenoma of the sigmoid colon. We performed pure laparoscopic sigmoidectomy, and the resected specimen was removed transanally. Intracorporeal anastomosis was then performed using a circular stapling device.
  
  
  RESULTS
  Although the patient had slight numbness of the right upper extremity, and the patient was discharged because no other complications were noted.
  
  
  CONCLUSIONS
  Laparoscopic colectomy performed with minimal incision could essentially increase the usage of this surgical technique. Our method is feasible for minimization of operative invasion because it involves specimen extraction through a natural orifice.
