In March 2009, a 25-yr-old captive female African elephant (Loxodonta africana) underwent an exploratory laparoscopy after several weeks of diarrhea, submandibular and ventral edema, and swelling on medial and lateral aspects of all feet. Although there have been recent advances in laparoscopic vasectomies in free-ranging African elephants in South Africa utilizing specially designed rigid laparoscopes and insufflation devices, this was the first attempt at using these same techniques for an exploratory purpose. The elephant was sedated in a static restraint chute and remained standing for the duration of the procedure. Laparoscopy provided visibility of the dorsal abdomen, enabled collection of reproductive tract biopsies and peritoneal fluid samples, and allowed for instillation of antibiotics and crystalloid fluids directly into the abdominal cavity. Abdominal exploration, collection of tissue samples, and local therapy is possible via standing laparoscopy in megavertebrates.
