Standing laparoscopic abdominal lavage using a suction-irrigation device in 2 horses with primary suppurative peritonitis.

The use of a laparoscopic suction-irrigation device in 2 standing horses for lavage of the abdomen for the treatment of primary suppurative peritonitis is reported. Two horses were presented with a 1- to 2-week history of weight loss. Abdominocentesis revealed highly elevated total nucleated cell count. Peritoneal lavage systems were placed in both horses, but complications prevented adequate lavage. Both horses underwent standing laparoscopy; the dorsal abdomen was explored and the abdomen was profusely lavaged, using a suction-irrigation device. The procedure was efficient and allowed adequate visualization of the dorsal abdomen and lavage. A successful outcome was achieved in both cases. Key clinical message: Lavage of the abdomen of horses with peritonitis can be achieved under standing sedation, using a laparoscopic technique. In appropriately selected cases, this allows for adequate visualization of the dorsal abdomen and efficacious abdominal lavage.
