Postoperative complications and mortality can occur many weeks or months after colic surgery. We are interested in the long-term outcome of these cases. This study documents patterns of mortality and morbidity among 341 horses that recovered from colic surgery March 1998-August 2000. The progress of each horse was rigorously followed by periodic telephone and postal questionnaires. Event time data were recorded for each animal and a total of 321 horse years of survival, together with death from all causes, colic-related death and various postoperative complications. Postoperative survival (of all horses excluding grass sickness cases) was triphasic over the first 600 days and there was marked mortality in the first 10 days postoperatively. The probability of survival postoperatively decreased to 0.87 by 10 days, 0.82 by 100 days and declined slowly to 0.75 at 600 days. Horses suffering from epiploic foramen entrapment had a significantly reduced probability of postoperative survival (RR = 2.1, P = 0.033). The causes of death for 104 horses that died postoperatively and the prevalence of postoperative complications are recorded for the study population. Postoperative colic was the most prevalent complication with 100 horses (29%) suffering one or more episodes. However, only 16 horses (4.6%) suffered 3 or more episodes. The incidence of postoperative colic was 0.55 episodes/horse year at risk. This study provides data that will inform the prognosis for postoperative colic cases and identifies epiploic foramen entrapment as carrying a worse prognosis for survival than other strangulating lesions.
术后并发症和死亡率可能在结肠手术数周或数月后出现。我们关注这些病例的长期预后。本研究记录了1998年3月至2000年8月间从结肠手术中康复的341匹马的死亡率和发病率模式。通过定期电话和邮寄问卷对每匹马的进展进行严格跟踪。记录每只动物的事件时间数据，以及总共321个马年的生存情况，包括各种原因导致的死亡、与结肠相关的死亡和各种术后并发症。术后生存情况（不包括青草搐搦病例的所有马匹）在最初600天呈三相变化，术后第10天死亡率显著。术后10天时生存概率降至0.87，100天时降至0.82，600天时缓慢降至0.75。患有网膜孔绞窄的马匹术后生存概率显著降低（相对危险度=2.1，P=0.033）。记录了研究群体中104匹术后死亡马匹的死因和术后并发症的发生率。术后结肠绞痛是最常见的并发症，100匹马（29%）发生一次或多次发作。然而，只有16匹马（4.6%）发作3次或更多次。术后结肠绞痛的发生率为0.55次/马年风险。本研究提供的数据将为术后结肠绞痛病例的预后提供参考，并确定网膜孔绞窄的生存预后比其他绞窄性病变更差。
