title: [Transendoscopic laser surgery of exercise-induced dorsal displacement of the soft palate in horses].
abstract: From 1995 to 1997 11 racehorses, one Hanoverian and one Pony were presented to the clinic with a sudden appearing, very loudly gurgling expiratory respiratory noise. Considering the preliminary report and the clinical and endoscopical findings, as exercise induced dorsal displacement of the soft palate (DDSP) was found to be the cause of the respiratory noise. The 13 horses were treated in general anaesthesia by transendoscopic coagulation of the caudal margin of the soft palate with a Neodym-YAG-Laser. This surgical intervention had to be repeated on four horses with unchanged signs. Eight of 13 horses (62%) did not show any respiratory noises after the operation. These horses were again successfully raced and ridden. Only an improvement was observed in two horses (15%), while in three patients (23%) the respiratory noise was unchanged after surgery. The laser chirurgic approach to the exercise induced DDSP offers, compared to previous therapies important advantages, like shorter recoveries, combined with similar success rates.
