AB Transanal  endoscopic  microsurgery  (TEM)  is  a  minimally  invasive  technique  for  the  excision  of  rectal  tumors  located  between  8  and  18  cm  above  the  anal  verge.  Lesions  located  below  8  cm  can  usually  be  approached  with  traditional  instruments,  whereas  exposure  using  a  traditional  transanal  approach  becomes  difficult  above  this  point.  TEM  provides  excellent  exposure  of  tumors  up  to  18  cm  from  the  anal  verge.  When  compared  to  the  techniques  of  low  anterior  resection,  parasacral  approach,  or  sphincter-splitting  approaches,  TEM  offers  greater  precision,  lower  morbidity,  and  a  shorter  hospital  stay.  The  technique  is  not  widely  established  because  of  the  specific  instrumentation  required,  the  unusual  technical  demands  of  the  approach,  and  the  specific  patient  selection  criteria.
