Intra-abdominal resection of the umbilical vein and urachus of bovine fetuses using laparoscopy and celiotomy: surgical time and feasibility (cadaveric study)

Abstract

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.

Laparoscopy-assisted percutaneous correction of abdominal wall defects in the umbilical region in a cadaveric model of bovine fetus

“…The UV and a large part of the hepatic parenchyma were initially visualized via laparoscopy, with great access to a large part of the abdominal cavity. The UV was first inspected as the laparoscope was focused directly on it [ 9 ]. The remaining umbilical structures were located by directing the laparoscope toward the umbilical base.…”

“…The methodology adopted by Monteiro et al [ 9 ] and Prządka et al [ 13 ] was used for the establishment of access portals, creation of a study model with the defect in the abdominal wall, and the execution of video-assisted percutaneous suturing technique. The access ports were established in the right flank near the paralumbar fossa, caudal to the ribs, with the direct introduction of the trocar via a parietal incision.…”

“…Videolaparoscopy is used for the intra-abdominal diagnosis of umbilical remnants, including repair of umbilical hernias in other species. This method exhibits promising results as compared with conventional methods via laparotomy [ 9 – 11 ].…”

“…Laparoscopic techniques need to be practiced in study models so that the surgeon acquires the skills to perform the procedure in live animals [ 9 , 10 ]. However, there are no reports on any experimental training model for creating an abdominal wall defect via the videosurgical approach.…”

Percutaneous ruminostomy guided by rumenoscopy: study in an experimental model in bovine fetus

“…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 ].…”
