Standing rectal and tail surgery.
A variety of rectal, perirectal, and coccygeal surgeries can be performed in the standing equine patient if appropriate chemical and physical restraints are available and adequate regional anesthesia can be achieved. Some rectal tears and most rectal prolapses, mass lesions, perirectal abscesses, rectal biopsies, and selected injuries of the tail can be managed without prohibitive difficulty. Severe injuries that compromise the small colon cranial to the peritoneal reflection may require flank laparotomy, midline celiotomy, or humane euthanasia to manage the disease process effectively and appropriately. The foremost perioperative consideration beyond the use of effective restraint is the management of tenesmus in horses with rectal tears or prolapses. Medications to control bowel motility, epidural anesthesia, antiinflammatory analgesics, and topical compounds adequate to soothe and lubricate inflamed rectal tissues are an important adjunctive therapy in the aftercare of these surgical patients. Of nearly equal importance is the requirement that a loose fecal consistency be maintained with laxative diets, psyllium, and mineral oil. Failure to maintain a loose consistency of stool after treatment of these conditions may lead to rectal impaction or incisional dehiscence and surgical failure.
