title: Management of the looping vas deferens during laparoscopic orchiopexy.
abstract: OBJECTIVE
  A number of variables should be assessed during laparoscopic orchiopexy, including vas anatomy. A looping vas deferens enters the inguinal canal and loops back to the abdominal cavity. This anatomical variant is not uncommonly encountered. Some groups considered this condition in their laparoscopic classification of nonpalpable testis. We present our experience with managing the looping vas during laparoscopic orchiopexy.
  
  
  METHODS
  We identified this condition in 18 procedures. In 14 cases it was possible to bring the vas back to the abdominal cavity. In 3 cases the loop could not be brought back laparoscopically and an inguinal incision was used. After the vas was dissected free and dropped into the abdominal cavity pneumoperitoneum was resumed and the procedure was completed laparoscopically. A Web based survey was done to test the value of this method.
  
  
  RESULTS
  A total of 17 procedures were completed successfully with preservation of the vas deferens while in 1 the vas was inadvertently cut. A looping vas did not significantly affect operative time. All 18 testes were viable and retained the scrotal position on followup scrotal Doppler ultrasound.
  
  
  CONCLUSIONS
  Verification of vasal anatomy is a crucial step that should be completed before any dissection. Bringing a looping vas back to the abdominal cavity is usually feasible laparoscopically but in a few cases this may require a small incision to dissect the vasal loop from its inguinal attachments.
