title: Evaluation of transanal endoscopic treatment of benign canine rectal neoplasia.
abstract: OBJECTIVE
  To evaluate transanal endoscopic treatment in the management of benign canine rectal neoplasia.
  
  
  METHODS
  A retrospective study was carried out to evaluate the response to transanal endoscopic treatment in 13 dogs with extensive rectal neoplasia that was considered inoperable by conventional surgical techniques but was indicated as benign by previous biopsy.
  
  
  RESULTS
  Tumours affected the lengths of rectal mucosa varying from 2 to 13 cm. Between 25 and 100 per cent of the rectal circumference was affected in each case. Transanal endoscopic treatment of canine rectal neoplasia was curative in five dogs, palliative in three and associated with a poor result in the remaining five. Complications of the technique included rectal perforation, leading to peritonitis and death.
  
  
  CONCLUSIONS
  Transanal endoscopic treatment can be recommended as an alternative to radical, full-thickness rectal excision for the management of extensive but benign canine rectal neoplasia. Owners should be informed that the treatment may be palliative rather than curative and that complications, if they occur, can be fatal. Dogs should be hospitalised for at least five days after treatment and observed for signs of potentially fatal complications such as rectal perforation.
