Ovariohysterectomy appears to have a low mortality rate in mares, but the procedure needs to be reviewed because of the high risk of life-threatening complications.
That ovariohysterectomy can be effective treatment for a variety of uterine diseases in mares and carries a good prognosis.
Diagnosis, clinical data, surgical technique, post operative care, complications and outcome were recorded from medical records of 7 mares that underwent total (6) and partial (1) ovariohysterectomy at the University of Illinois from 1994 to 2001.
The indications for ovariohysterectomy were chronic pyometra (4 mares), chronic uterine torsion (n = 2) and chronic intramural haematoma (n = 1). Surgical exposure was difficult but was improved by traction on stay sutures and right-angled clamps. In some cases, application of the TA-90 autosuture instrument as a right-angled clamp to the caudal part of the uterus improved access to the uterine stump. The most common post operative complications were decreased faecal output, decreased intestinal sounds (4 mares) and mild abdominal pain (2). Two mares had mild to moderate incisional infections. Other previously reported complications, such as haemorrhage, septic peritonitis, uterine stump infection or necrosis, and diarrhoea, did not occur. All mares survived over follow-up periods of 6 months to 5 years and were used for riding (6 mares) and embryo transfer (1 mare, after partial ovariohysterectomy).
According to this study, the prognosis for mares after ovariohysterectomy appears to be good, despite the technical difficulties of the procedure. The prevalence of life-threatening complications can be lower than reported.
卵巢子宫切除术在母马中似乎死亡率较低，但由于存在危及生命的并发症的高风险，该手术仍需重新评估。
卵巢子宫切除术可有效治疗母马的多种子宫疾病，且预后良好。
记录了1994年至2001年在伊利诺伊大学接受全子宫切除术（6例）和部分子宫切除术（1例）的7匹母马的病历，包括诊断、临床数据、手术技术、术后护理、并发症及结果。
卵巢子宫切除术的适应症为慢性子宫积脓（4匹母马）、慢性子宫扭转（n = 2）和慢性壁内血肿（n = 1）。手术暴露困难，但通过牵引留置缝线和直角钳可有所改善。在某些情况下，将TA - 90自动缝合器械作为直角钳应用于子宫尾部可改善对子宫残端的暴露。最常见的术后并发症是粪便排出减少、肠鸣音减弱（4匹母马）和轻度腹痛（2匹）。2匹母马有轻度至中度切口感染。其他先前报道的并发症，如出血、感染性腹膜炎、子宫残端感染或坏死以及腹泻均未发生。所有母马在6个月至5年的随访期内存活，其中6匹用于骑乘，1匹（部分卵巢子宫切除术后）用于胚胎移植。
根据本研究，尽管该手术存在技术困难，但母马卵巢子宫切除术后的预后似乎良好。危及生命的并发症发生率可能低于报道。
