Summary A late term broodmare presented with low‐grade intestinal colic. Clinical findings were consistent with a small intestinal lesion requiring surgical intervention. The risks of general anaesthesia to the fetus, combined with clinical findings in an otherwise quiet natured horse influenced the decision to choose an alternative standing left flank approach first. A small intestinal resection and anastomosis was performed successfully and the mare delivered a healthy foal without complications a month later. Standing colic surgery might be a preferred alternative to general anaesthesia in certain circumstances as discussed in this case report.

“…There is a good prognosis following standing laparoscopic removal of large, pathological ovaries and low complication rates are reported: 99-100% of cases are reported to return to their previous level of work and 85-93% of cases are successfully bred within 30 months after surgery (Hubert et al 2006;Lloyd et al 2007;de Bont et al 2010;Kummer et al 2010;R€ ocken et al 2011;Kelmer et al 2013). Short-term survival rates for HP vary from 39 to 74% (Pusterla et al 2005;Dechant et al 2006;Conwell et al 2010).…”

SummaryThis report describes two cases of successful surgical management of granulosa cell tumours (GCT) in mares presenting with haemoperitoneum (HP). Controlled abdominal drainage was initially attempted in Case 1 but was not successful. A ventral midline exploratory laparotomy allowed removal of a haemorrhaging 13 kg GCT. The mare made a full recovery and returned to normal work as a driving pony 11 months post-operatively. In Case 2 controlled abdominal drainage was followed by standing left flank laparoscopic visualisation of the bleeding ovary and transection of the ovarian pedicle by electrocautery. The GCT was then removed via a ventral midline incision due to its large size. Haemoperitoneum can be associated with GCTs and in some cases is severe enough to prompt emergency treatment. Stabilisation of the patient and removal of the haemorrhaging GCT can lead to a successful outcome.

“…Vários métodos já foram utilizados para a hemostasia de ovariectomia laparoscópica, dentre eles nós pré-atados [1], eletrocirurgia bipolar, energia monopolar e vibração ultrassônica [5]; radiofrequência e grampeadores [11]. Apesar de ser considerada o padrão ouro para ovariectomia [12], a técnica laparoscópica exige experiência com a tecnologia utilizada, além de possuir um custo elevado para sua aplicação de maneira adequada [10]. Por essa razão a busca por alternativas com custo mais acessível ao veterinário torna-se importante para ampliar a utilização desta modalidade cirúrgica.…”

Background: Laparoscopic ovariectomy it is used more than 20 years in veterinary medicine, however, information of this technique in Brazil are rare. Also, the cost for his execution are high, specially the ovarian hemostasis procedure, that depends on highly specialized surgical instruments. The goal of this study is show the results achieved during laparoscopic ovariectomy in mares using a device to apply and cut tie-wraps, developed by the authors and that is in a patent process.Materials, Methods & Results: Four mares with ovarian pathologies were selected for a standing unilateral ovariectomy procedure and access to cavity occurred through three laparoscopic portals. The vessels and ligament were dissected to allow positioning of a polyamide tie-wrap by the device for cutting and applying those seals. Occlusion was made by pushing, and cutting through a rotation on the tie latch. Then, the mesovarium was cut with laparoscopic scissors and ovary removed by a communication between two accesses. Total surgical time and the equipment handling were noted. The average duration of surgical procedures was 80 ± 12.35 min and device handling time since its external preparation, application and cutting the polyamide tie-wraps was 3.4 ± 2.63 min. Only in one of four animals it was necessary to apply more than one tie, since the first promoted incomplete vessels occlusion. Within 10 postoperative days none of the animals showed clinical signs consistent with bleeding and / or infection and the wound’s healing were complete.Discussion: Surgical time for dissection and hemostasis during laparoscopic ovariectomy in mares shows great variation in the literature and depend on hemostasis technique. The average time of 80 min for a one-sided procedure using the device for application and cutting tie-wraps was considered appropriate, with the possibility of significantly reduction, since this is an instrumental in testing and yet there is not a definition of the learning curve from its use. The main reason related to the tie-wraps use, even controversial, is due a significant reduction in cost, since the devices for hemostasis available are very expensive to brazilian veterinarians. Although considered a simple application and advantages over other hemostatic methods the authors of this study do not indicate the use of non-surgical polyamide ties when other materials are available, also, it is important to clarify that the main purpose of this study was to report the effectiveness of the device for application and cut these ties while performing these surgical procedure steps. The device for applying and cutting tie-wraps allows closing and resection of polyamide tie-wraps, producing safe hemostasis to ovarian vessels during laparoscopic ovariectomy in mares, with appropriate surgical time and without trans or postoperative complications.
