title: Standing abdominal surgery.
abstract: Safe, effective surgery can be performed in the standing, conscious horse using a combination of mechanical and chemical restraint. Clear indications for performing standing abdominal surgery exist, but many procedures are best performed under general anesthesia. The preferred approach involves a modified grid incision of the left paralumbar fossa. Flank celiotomy allows the surgeon to thoroughly explore the abdominal cavity, but few structures can be exteriorized, and visibility of abdominal contents is poor. Indications for standing abdominal surgery include diagnosis of abdominal masses, drainage and biopsy techniques, correction of left dorsal displacement of the large colon, and evaluation of rectal injuries, and performing loop colostomy techniques, laparoscopy, removal of retained testicles, correction of uterine torsions, surgical embryo transfer, ovariectomy in normal mares, and some experimental procedures. Standing surgical techniques are most useful and appropriate for surgical exploration, to correct uterine torsions, and to perform loop colostomy and surgical embryo transfer techniques. Perioperative antimicrobial and antiinflammatory therapy is recommended. Mild discomfort and ventral incisional swelling after surgery are expected.
