A minority of equine colic cases prove fatal unless treated surgically; however, few studies have considered long-term survival and complication rates, and few have attempted to identify factors that might affect outcomes. Such information is required for owners and veterinary surgeons to make informed decisions about the most appropriate treatment for individual cases.
To document short-term survival rates of 300 horses undergoing colic surgery and analyse factors that might have predisposed to short-term death.
History, clinical and surgical findings, treatments and outcomes of 300 surgical colic cases (1994-2001) were reviewed. Comparisons among groups of discrete data were made using chi-squared or Student's t tests as appropriate. Significance was set at P < 0.05, and 95% confidence intervals were calculated for percentages.
The short-term survival rate (to discharge) was 70.3% for all horses and 83.1% for those recovering from anaesthesia; for horses that had a single laparotomy it was 87.2%. The most common reasons for death/euthanasia in the post operative period after a single laparotomy were persistent pain/colic, post operative ileus and grass sickness. Horses with lesions involving the small intestine and caecum had lower survival rates (75.2 and 66.7%, respectively) than those with large colon or small colon lesions (89.9 and 100%, respectively). The survival rate for ischaemic/strangulating lesions (68.9%) was lower than for simple obstructions (90.5%).
Short-term survival of horses undergoing exploratory laparotomy for acute colic is dependent on many factors, including the nature of the underlying disease, cardiovascular status and post operative complications.
These retrospective studies may be used as a basis for prospective studies assessing treatments that could ultimately improve survival and decrease complication rates.
少数马属动物绞痛病例若不进行手术治疗会导致死亡；然而，很少有研究考虑长期存活率和并发症发生率，也很少有研究试图确定可能影响治疗结果的因素。此类信息对于马主和兽医就个别病例选择最合适的治疗方法做出明智决策而言至关重要。
记录300匹接受绞痛手术的马的短期存活率，并分析可能导致短期死亡的因素。
回顾了300例手术治疗绞痛病例（1994 - 2001年）的病史、临床及手术发现、治疗方法和治疗结果。对离散数据组之间进行比较时，根据情况使用卡方检验或学生t检验。显著性设定为P < 0.05，并计算百分比的95%置信区间。
所有马的短期存活率（至出院）为70.3%，麻醉后恢复的马为83.1%；接受单次剖腹手术的马为87.2%。单次剖腹手术后，围手术期死亡/安乐死的最常见原因是持续性疼痛/绞痛、术后肠梗阻和青草搐搦症。涉及小肠和盲肠病变的马的存活率（分别为75.2%和66.7%）低于涉及大结肠或小结肠病变的马（分别为89.9%和100%）。缺血/绞窄性病变的存活率（6旦沪测疚爻狡诧挟超锚8.9%）低于单纯梗阻的存活率（90.5%）。
接受急性绞痛探查性剖腹手术的马的短期存活取决于许多因素，包括潜在疾病的性质、心血管状况和术后并发症。
这些回顾性研究可作为前瞻性研究的基础，以评估最终可提高存活率并降低并发症发生率的治疗方法。
