Records of 75 horses with ileal impactions were examined retrospectively. There was a sex predilection towards mares. Arabians were over-represented compared to the hospital population. The average age was 8.3 years. Abdominal pain was observed in 96% of horses. Nasogastric reflux was present in 56% of horses, small intestinal distention was found on rectal palpation in 96% and an ileal impaction in 25%. Exploratory celiotomy was performed in 69 horses, the mass was reduced by extramural massage in 67 horses, and ingesta was removed via enterotomy in 2. Jejunocecostomies were performed in 47 horses. Twenty-five horses developed postoperative ileus, and 11 developed laminitis. Twenty-seven horses survived. Significant differences (p less than 0.05) between survivors and non-survivors were found for rectal temperature (37.7 and 38.2 degrees C, respectively), plasma protein concentration (7.8 and 8.9 g/dl, respectively) and anion gap (15 and 21.3 mEq/l, respectively). Survival decreased with increasing duration of clinical signs. Enterotomy, enterectomy, and/or jejunocecostomy performed during surgery had a deleterious effect on survival.
对75匹患有回肠阻塞的马匹记录进行了回顾性研究。母马更易发病。与医院总体马匹数量相比，阿拉伯马的比例过高。平均年龄为8.3岁。96%的马匹出现腹痛。56%的马匹有鼻胃反流，96%的马匹直肠触诊发现小肠扩张，25%的马匹有回肠阻塞。69匹马进行了剖腹探查术，67匹马通过壁外按摩使肿块缩小，2匹马通过肠切开术清除内容物。47匹马进行了空肠回肠吻合术。25匹马发生术后肠梗阻，11匹马发生蹄叶炎。27匹马存活。存活者与非存活者在直肠温度（分别为37.7和38.2摄氏度）、血浆蛋白浓度（分别为7.8和8.9 g/dl）和阴离子间隙（分别为15和21.3 mEq/l）方面存在显著差异（p小于0.05）。随着临床症状持续时间的增加，存活率下降。手术期间进行的肠切开术、肠切除术和/或空肠回肠吻合术对存活率有不利影响。
