Standing laparoscopic‐assisted vaginal ovariohysterectomy in a mare

Abstract

Summary A 20‐year‐old Arabian mare presented to Washington State University Veterinary Teaching Hospital for evaluation of haemorrhagic vaginal discharge of 3 months' duration. The referring veterinarian had identified a mass within the uterine wall via transrectal ultrasonographic examination. On presentation, the mare had an unremarkable physical examination with the exception of a mild haemorrhagic vaginal discharge. Rectal palpation was performed and an approximately 9 cm diameter mass with a granular texture was identified associated within the uterine body and left uterine horn. Endoscopic examination of the reproductive tract revealed a linear defect in the ventral uterine wall near the cervix with direct communication into the abdomen. Standing laparoscopic‐assisted vaginal ovariohysterectomy (OHE) was performed, which involved laparoscopic facilitated dissection and haemostasis of uterine and ovarian structures, and inversion of the uterus through the cervix. Removal of the uterus was performed vaginally. No post operative complications were noted. Standing laparoscopic‐assisted vaginal OHE is an alternative to traditional OHE techniques. This technique allowed for excellent direct visual observation during dissection and ligation and did not require general anaesthesia.

Endoscopic‐Assisted Resection of a Pedunculated Uterine Leiomyoma With Maximal Tissue Preservation in a Cow and a Mare

“…Restitution of fertility is usually the main objective in large domestic animals with reproductive commercial value. Several different surgical techniques have been described to remove a leiomyoma . Based on the human literature and the positive long‐term outcome reported, and considering the age of both animals, a minimally invasive approach with maximum preservation of the uterine tissue was chosen.…”

“…With this particular presentation early surgical intervention is recommended in domestic animals and women . Several different techniques have been described in large animals including intrauterine removal with an electrosurgical loop, resection via laparotomy, and partial hysterectomy/ovariohysterectomy using conventional or minimally invasive assisted techniques . Based on the reported low recurrence of leiomyoma, treatment options in women are based on minimally invasive procedures with maximum preservation of uterine tissue…”

Laparoscopic ovariohysterectomy in the equine; an elusive goal

“…) or rare malignant neoplasias such as adenocarcinoma (Gablehouse et al . ). Partial hysterectomies are usually sufficient for the majority of uterine benign neoplasia (usually leiomyoma) and can allow future reproduction (Santschi and Slone ).…”

“…The ovaries are removed along with the uterus to preclude future oestrous behaviour, but it is not known if ovariectomy is required for medical reasons. Ovariohysterectomy is also uncommonly used to treat symptomatic extensive benign neoplasia of the uterus (Broome et al 1992) or rare malignant neoplasias such as adenocarcinoma (Gablehouse et al 2009). Partial hysterectomies are usually sufficient for the majority of uterine benign neoplasia (usually leiomyoma) and can allow future reproduction (Santschi and Slone 1994).…”
