Standing laparoscopic herniorrhaphy in stallions using cylindrical polypropylene mesh prosthesis

Standing laparoscopic herniorrhaphy was performed in 9 stallions. Appropria te analgesia was achieved by sedation with detomidine and local flank infil tration with mepivacaine. Three portal sites at the paralumbar fossa were u sed to perform the herniorrhaphy by means of triangulation. A cylindrical p olypropylene mesh was inserted and fixated in the inguinal canal. Subsequen t adhesion formation resulted in an obliterated inguinal canal within 2 wee ks. This minimal invasive technique allowed us to perform a testis sparing herniorrhaphy in the standing horse.
