25Surgical intervention for umbilical diseases in calves, when indicated, is a 26 complementary and indispensable therapeutic resource for the treatment of umbilical 27 conditions and is commonly performed using celiotomy. However, videolaparoscopy has 28 demonstrated feasibility in many diagnostic and therapeutic procedures. The aim of this study 29 was to assess the feasibility of the techniques and the surgical time of videolaparoscopy and 30 celiotomy used in intra-abdominal resection of the umbilical vein and urachus of bovine 31 fetuses (cadavers). Resection of the umbilical vein and urachus using videolaparoscopy and 32 celiotomy was performed in 26 anatomical specimens (bovine fetuses obtained from an 33 official slaughterhouse). Resection of umbilical structures was feasible with both techniques, 34 but shorter surgical time and minimal tissue damage were achieved using videolaparoscopy. 35 Laparoscopy requires specialized training and appropriate instruments and is an important 36 tool for diagnostic and therapeutic exploration of the umbilical structures, liver, bladder, and 37 associated/adjacent structures.
