“…Minimally invasive techniques tend to have less surgical time than conventional techniques. In the newly developed video-assisted rumenostomy technique, the time obtained was 13 ± 6.2 min [ 31 ], while in conventional techniques, the surgical time varies from 15 to 25 min [ 33 ] when performed in a surgical stage. In humans, percutaneous endoscopic gastrostomy was performed in 8 ± 3 min, while the open surgical gastrostomy technique had a mean duration of 35 ± 1.3 min [ 11 ].…”

“…In this same procedure, the 36-h fast, combined with the decubitus, allowed a good visualization and manipulation of the rumen, in addition to avoiding regurgitation and inhalation of rumen contents. However, although the percutaneous endoscopic rumenostomy has not yet been tested in live animals, it is believed that the rumenoscopy technique can be performed in standing animals [ 13 , 14 , 31 ].…”

“…Thus, the proposed models are the most compatible, because conventional cannulas would interfere with the gas exchange of the rumen with the ambient air, due to cannula displacement, a relatively frequent event [ 35 ], as well as at the moment of opening the cannula. These problems were the factors that encouraged our team to develop an in vivo model of minimally invasive rumenostomy in sheep [ 31 ], since rumen puncture for many days would bring injury, cannula opening, and ambient air intake, and an oral probe would contaminate the sample with saliva. However, the model can also be executed by new proposed techniques, in simpler and more practical ways.…”

Background Endosurgery 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. Results The 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. Conclusions The 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.

“…Because it is a minimally invasive technique, it is important to determine whether it is possible to perform it under regional anesthesia and sedation, a suitable alternative for treating calves with umbilical disorders associated with concomitant diseases and with reduced ability to adapt to general anesthesia 15 . Other studies have shown that laparoscopic techniques are less traumatic than conventional open techniques 32 – 35 .…”

Surgical intervention for umbilical diseases in calves, when indicated, is a complementary and indispensable therapeutic resource for the treatment of umbilical conditions and is commonly performed using celiotomy. However, laparoscopy has demonstrated feasibility in many diagnostic and therapeutic procedures. The aim of this study was to assess the feasibility of the techniques and the surgical time of laparoscopy and celiotomy used in intra-abdominal resection of the umbilical vein and urachus of bovine fetuses (cadavers). Resection of the umbilical vein and urachus using laparoscopy and celiotomy was performed in 26 anatomical specimens (bovine fetuses obtained from an official slaughterhouse). Resection of umbilical structures was feasible with both techniques, but shorter surgical time and minimal tissue damage were achieved using laparoscopy. Laparoscopy requires specialized training and appropriate instruments and is an important tool for diagnostic and therapeutic exploration of the umbilical structures, liver, bladder, and associated/adjacent structures.
