Foals with these disturbances have high morbidity and mortality rates. The conventional omphalectomy technique does not remove the whole umbilical vein, which can lead to infection in the remnant vein or even liver abscess. At the moment, if the whole umbilical vein needs to be removed, a longer ventral midline incision must be performed, which is linked with several complications. This retrospective case series study focused on a modified two-step omphalectomy using the LigaSureTM device in each step in five neonate foals (4 horses and 1 donkey) with umbilical disorders. Using this modified technique, the whole umbilical vein (from the stump to the liver) can be removed without the need of incision extension. Two foals in this series had complications not related with the surgery and had to be euthanized. In the surviving foals (three of five), no long-term complications have been reported. Therefore, this modified two-step technique using the LigaSureTM device could be a suitable surgical option to decrease short- and long-term complications in neonate foals undergoing umbilical surgery. However, a multicentric prospective study on a larger number of animals is required.<\/jats:p>","DOI":"10.3390\/ani15070981","type":"journal-article","created":{"date-parts":[[2025,4,2]],"date-time":"2025-04-02T16:26:31Z","timestamp":1743611191000},"page":"981","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Description of a Modified Two-Step Omphalectomy Technique Using the LigaSure\u2122 Device to Remove the Whole Extrahepatic Umbilical Vein: A Case Series Study in Equine and Donkey Foals"],"prefix":"10.3390","volume":"15","author":[{"given":"Antonio","family":"Buzon-Cuevas","sequence":"first","affiliation":[{"name":"Department of Animal Medicine and Surgery, University of Cordoba, 14014 Cordoba, Spain"},{"name":"Veterinary Teaching Hospital, University of Cordoba, 14014 Cordoba, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan","family":"Duaso","sequence":"additional","affiliation":[{"name":"Department of Animal Medicine and Surgery, University of Cordoba, 14014 Cordoba, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonia","family":"Sanchez de Medina","sequence":"additional","affiliation":[{"name":"Department of Animal Medicine and Surgery, University of Cordoba, 14014 Cordoba, Spain"},{"name":"Veterinary Teaching Hospital, University of Cordoba, 14014 Cordoba, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan M.","family":"Sierra","sequence":"additional","affiliation":[{"name":"Department of Animal Medicine and Surgery, University of Cordoba, 14014 Cordoba, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4086-0940","authenticated-orcid":false,"given":"Alejandro","family":"Perez-Ecija","sequence":"additional","affiliation":[{"name":"Department of Animal Medicine and Surgery, University of Cordoba, 14014 Cordoba, Spain"},{"name":"Veterinary Teaching Hospital, University of Cordoba, 14014 Cordoba, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7725-8080","authenticated-orcid":false,"given":"Francisco J.","family":"Mendoza","sequence":"additional","affiliation":[{"name":"Department of Animal Medicine and Surgery, University of Cordoba, 14014 Cordoba, Spain"},{"name":"Veterinary Teaching Hospital, University of Cordoba, 14014 Cordoba, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"876","DOI":"10.1111\/evj.13267","article-title":"Normal regression of the internal umbilical remnant structures in Standardbred foals","volume":"52","author":"McCoy","year":"2020","journal-title":"Equine Vet.
