Topic:Celiotomy
Celiotomy, also known as laparotomy, is a surgical procedure involving an incision into the abdominal cavity of horses. It is performed for diagnostic or therapeutic purposes, often to address conditions such as colic, abdominal masses, or reproductive issues. The procedure allows veterinarians to directly examine and treat internal organs, including the intestines, liver, and uterus. Various techniques and approaches are used depending on the underlying condition and the horse's anatomy. This page compiles peer-reviewed research studies and scholarly articles that explore the indications, surgical techniques, postoperative care, and outcomes associated with celiotomy in equine patients.
