title: [Minimal invasive transvaginal right hemicolectomy: report of the first complex NOS (natural orifice surgery) bowels operation using a hybrid approach].
abstract: BACKGROUND
  Laparoscopic surgery has dramatically changed abdominal surgery by reducing the risk of wound infections, incisional hernias and adhesions. The surgical concept using natural orifices (NOS) may be even less traumatic and so less invasive.
  
  
  METHODS
  This operation was performed in a 66-year-old woman with an adenoma in the ascending colon. Through a 5 mm incision at the umbilicus a pneumoperitoneum was created and a trocar inserted. For the operation a 12 mm trocar and a curved grasper have been inserted in the posterior fornix of the vagina. Because of adhesions an additional 5 mm trocar was necessary. Through this incision the laparoscopic right hemicolectomy with an intracorporal anastomosis was performed.
  
  
  RESULTS
  The histology showed an adenoma with 21 lymph nodes. The removal of the specimen through the vagina was without any difficulties. The postoperative course was regular.
  
  
  CONCLUSIONS
  This operation is to our knowledge the first right hemicolectomy as a NOS/NOTES-operation in a human patient. It shows that with rigid instruments even complex procedures through natural orifices are feasible.
