“…Strategies to avoid general anesthesia for diagnostic and surgical procedures are implemented by continuous efforts to refine and develop anesthetic protocols that allow standing surgical interventions and advanced diagnostic imaging . Sedatives and anesthetic agents cause ataxia, which in turn may lead to injury when horses attempt to stand during the recovery phase from general anesthesia .…”

Objective To investigate the feasibility and complications associated with ceratohyoidectomy (CHE) in standing sedated horses unaffected (experimental horses) and standing sedated horses affected (clinical cases) with temporohyoid osteoarthropathy (THO). Study design Case series. Animals Six experimental horses and four clinical cases. Methods Standing CHE was performed in six experimental horses euthanized 30 minutes (n = 3) and 7 days (n = 3) postoperatively. The four clinical cases were presented because of central facial nerve paralysis (n = 3), vestibular ataxia (n = 3), auricular hemorrhage (n = 2), quidding (n = 1), and oesophageal impaction (n = 1). Evolution was assessed by clinical examination during hospitalization and later by telephone interviews for the clinical cases. Results The procedure was successfully performed in all horses. Experimental horses did not show any short‐term postoperative complications. Hemorrhage was experienced intraoperatively in one of the clinical cases and was successfully managed with placement of hemostatic forceps. Vestibular ataxia and other symptoms of THO improved within days, but facial nerve paralysis did not improve until 9 days to 6 months after surgery. Follow‐up ranged from 9 to 24 months. All clinical cases returned to performance, and client satisfaction was excellent. Conclusion Ceratohyoidectomy was consistently feasible in standing sedated horses. The method did not result in postoperative complications and led to resolution of clinical signs associated with THO. Clinical significance Standing CHE should be considered in horses affected with THO, especially when horses present with marked vestibular deficits and ataxia, to reduce risks associated with recovery from general anesthesia.

“…Procaine penicillin (22 000 IU/kg IM) and flunixin meglumine (1.1 mg/kg IV) were administered 60 minutes before surgery. The horses were sedated with detomidine hydrochloride (0.01 mg/kg IV) (Medesedan 1%, Chanelle UK, Hungerford, UK) and butorphanol tartrate (0.01 mg/kg IV) (Butador 1%, Chanelle UK ) as a bolus and maintained on a constant rate infusion of detomidine (0.01 mg/kg/h) throughout surgery . The head and neck of each horse was extended and placed on a dental headrest.…”

Objective: To describe a surgical technique for thyroidectomy in horses with thyroid neoplasia under standing sedation and local anesthesia.Study design: Retrospective study.Animals: Client-owned horses (n 5 10).Methods: Medical records of horses with a history of thyroid enlargement were included in the study if thyroid gland enlargement was treated surgically via hemi-or bilateral thyroidectomy, with the horse standing and sedated. Data derived from follow-up clinical examination, performance level, recurrence, and cosmetic outcome were evaluated.Results: Thyroid enlargement was unilateral in 8 and bilateral in 2 horses. Histopathological findings included adenomas (5/10), adenocarcinomas (2/10), cystic hyperplasia (2/10), and C-cell adenoma (1/10). No major complications were encountered during or after surgery. All horses resumed their previous level of exercise within 6 weeks. Recurrence was diagnosed in 1 horse, 7 months after excision, and a second surgery was required. Recurrent laryngeal nerve neuropathy and seroma formation subsequent to surgery were not recorded in any of the cases.Conclusion: Thyroidectomy can safely be performed with the horse standing and sedated with local anesthesia.Clinical relevance: Performing standing thyroidectomy does not increase intraoperative or postoperative complications and could be considered for horses with thyroid enlargement amenable to surgery.

“…Colic during late pregnancy in the broodmare is a diagnostic and therapeutic challenge mainly due to the presence of a large gravid uterus that obscures imaging and limits internal examination, but also because both fetal and maternal welfare need considering simultaneously (Santschi ). Emergency laparotomy complication rates for colic have been well reported (Vigani and Garcia‐Pereira ) and wound complications are common (Mair and Smith ,b; Costa‐Farre et al . ) but in broodmares, prolonged procedures and hypotension are also associated with negative fetal outcomes, particularly in late pregnancy (Chenier and Whitehead ).…”

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.
