Abstract

BackgroundEndosurgery is a surgical subspecialty that has been widely used in production animals, because it enables good visualization of abdominal organs and the diagnosis and treatment of several conditions in a minimally invasive manner, while preserving the animal’s well-being and causing a lower impact on animal production. Rumenostomy is one of the most common surgical procedures in ruminants. This procedure is used to allow access to the rumen for various purposes, especially nutritional and therapeutic studies, and it can be performed either in a conventional way or in a minimally invasive video-assisted manner. Another possibility of access to ruminants is through the rumenoscopy technique. The objective of this study is to describe a minimally invasive technique for rumenostomy using an endoscope, working on a bovine fetal corpse as an experimental model.ResultsThe execution of the endoscopy-guided rumenostomy technique was simple and did not present major difficulties. The endoscope, its lighting and air pump, and the decubitus used provided a good anatomical visualization of the rumen, and it was possible to evaluate several regions of the organ. The mean duration of the procedure was 11.15 min.ConclusionsThe endoscopic rumenostomy technique using anatomical pieces of calves was shown to be feasible. It was performed in a simple and efficient way, particularly regarding the premise of preserving the animal’s well-being, due to its minimally invasive nature.

Highlights

Endosurgery is a surgical subspecialty that has been widely used in production animals
It has shown increasingly promising results [26] and in many cases has become the surgical technique of choice, since it allows good visualization of abdominal organs [4] and the diagnosis and treatment of several conditions in a minimally invasive manner, while preserving the animal’s well-being and causing a lower impact on animal production [34]
Laparoscopy can be performed for various purposes, such as abomasopexy [1], kidney biopsy [7], liver biopsy [10], cystotomy [15] ovariectomy [2, 3, 34]

It is used to open an access to the rumen, either temporarily or permanently, and has several purposes, animal nutrition studies to assess digestibility and rumen metabolism and to evaluate animals that will serve as donors of ruminal inoculum [29, 32, 37], in addition to therapeutic purposes, such as cases of relapsing tympanism due to vagal indigestion [30], calves with tympanism due to esophageal groove dysfunction [22], and enteral nutrition [5]
