This retrospective study describes the clinical and laboratory findings, treatment and outcome of 461 cattle with caecal dilatation.
The general condition and demeanor were abnormal in 93.1% of cases, and 32.1% of the patients had colic. Ruminal motility was reduced or absent in 78.3% of cattle. In 82.6% of cases, swinging and/or percussion auscultation were positive on the right side, and 82.4% had little or no faeces in the rectum. Caecal dilatation could be diagnosed via rectal palpation in 405 (88.0%) cattle. There was caudal displacement of the dilated caecum in 291 patients, torsion around the longitudinal axis in 20 and retroflexion in 94. The most important laboratory finding was hypocalcaemia, which occurred in 85.1% of cases. Of the 461 cattle, 122 (26.5%) initially received conservative therapy (intravenous fluids, neostigmine, calcium borogluconate) and 329 (71.4%) underwent surgical treatment. Ten patients were slaughtered or euthanased after the initial physical examination. Of the 122 cattle that received conservative treatment, 42 did not respond after one to two days of therapy and required surgical treatment. The final number of cattle that were operated was 371 (80.5%). Because of a grave prognosis, 24 cases were euthanased or slaughtered intraoperatively. Another 24 cattle did not respond to one or more operations and were euthanased or slaughtered. Of the 461 patients, 403 (87.4%) responded to either conservative or surgical treatment and were cured, and 58 were euthanased or slaughtered.
Caecal dilatation can usually be diagnosed based on clinical findings and treated conservatively or surgically. Swinging and percussion auscultation as well as rectal examination are important diagnostic tools. Conservative treatment is not rewarding in cattle considered surgical candidates with suspected caecal torsion or retroflexion and surgery should not be delayed in these patients.
本回顾性研究描述了 461 头牛的盲肠扩张的临床和实验室检查结果、治疗方法和转归。
93.1%的病例一般状况和精神状态异常,32.1%的患畜出现腹痛。78.3%的患畜瘤胃蠕动减少或消失。82.6%的病例右侧摆动和/或叩诊听诊阳性,82.4%的患畜直肠内几乎没有或没有粪便。通过直肠触诊可诊断 405 例(88.0%)患畜盲肠扩张。291 例患畜扩张盲肠向尾部移位,20 例盲肠扭转,94 例盲肠反转。最重要的实验室发现是低钙血症,发生于 85.1%的病例。461 例患畜中,122 例(26.5%)最初接受保守治疗(静脉补液、新斯的明、葡萄糖酸钙),329 例(71.4%)接受手术治疗。10 例患畜在初步体检后被宰杀或安乐死。接受保守治疗的 122 例患畜中,42 例在治疗 1-2 天后无反应,需要手术治疗。最终手术的患畜为 371 例(80.5%)。由于预后严重,24 例患畜在手术中被安乐死或宰杀。另有 24 例患畜经一次或多次手术治疗后无反应,被安乐死或宰杀。461 例患畜中,403 例(87.4%)经保守或手术治疗后反应良好并治愈,58 例被安乐死或宰杀。
盲肠扩张通常可根据临床发现进行诊断,并进行保守或手术治疗。摆动和叩诊听诊以及直肠检查是重要的诊断工具。对于疑似盲肠扭转或反转且被认为是手术候选的患畜,保守治疗效果不佳,不应延误手术。
