본 연구는 한국마사회 동물병원에서 시행한 전신마취 결과를 분석하고 마취 중 후에 발생한 사망률에 영향을 미치는 인자를 찾기 위하여 실시되었다. 총585두의 환마에서 전신마취가 실시되었으며, 수술의 빈도는 정형외과 수술(410)이 가장 많이 실시되었고, 산통 수술(85), 호흡기 수술(45) 순이었다. 585두 중 20두가 마취 중 후에 죽거나 안락사 되었다. 20두 중 14두는 산통 수술을 받았고, 3두는 정형외과 수술, 3두는 호흡기 수술을 받았다. 세부 사망원인으로는 산통 수술에서는 장파열, 호흡기 수술에서는 기도폐색이었다. 정형외과 수술에서는 근육병증, 재골절, 제엽염이 안락사의 원인이었다. 결과적으로 산통 수술과 호흡기 수술 후의 사망률은 정형외과 수술 후보다 높게 나타났다 (p < 0.01). 이상의 결과로부터, 산통수술을 받는 말의 사망률이 가장 높은 것을 확인하였으며, 그 원인은 예후불량에 의한 안락사이었다. 말의 마취 전후 사망률을 낮추기 위하여, 산통 수술을 받는 말은 수술 전후의 집중 관리가 필요하고, 호흡기 수술을 받는 말은 회복 중 주의 깊은 관찰이 추천된다.

산통은 이환률과 치명률이 높아 말 산업에 가장 우려되는 질병이다. 많은 나라에는 산통마의 내과적, 외과적 치료에 따른 치명률과 예후인자 평가를 위한 연구 결과가 있지만 한국에서는 산통의 예후 판단을 위한 객관적 연구가 이루어지지 않았다. 본 논문에서 한국 산통마의 치명률을 확인하고, 잠재적 예후 인자들을 평가를 하고자 하였다. 2011년 1월부터 2013년 12월까지 한국마사회에 내원한 119마리의 산통마를 대상으로 조사하였다. 유의성을 평가하기 위하여 카이제곱검정, T-test와 Mann-Whitney test를 사용하였다. 그 결과, 전체 치명률은 15%였으며 내원한 산통마 중 78%가 내과적 치료를 받았다. 개체적 인자인 성별, 나이, 내원 시기는 예후와 유의성은 없었으나 3세 이하 (59%)의 수컷 (50%)에서 발생률이 높았다. 탈수의 대표적 지표인 구강점막의 색깔과 PCV는 생존집단과 폐사집단사이에 유의적인 차이를 보였다. 그 외 신체적 인자인 심박수, 장운동성 그리고 직장온도도 예후와 유의적으로 관련이 있었다. 임상병리인자 중에는 적혈구수, 혈색소농도, 충진세포용적, 혈소판수, 크레아틴키나아제(CK), 젖산탈수소효소(LDH), 혈당치가 산통의 예후인자로서 통계적으로 유의성이 있음을 확인하였다.

This case report describes the clinical presentation and successful surgical repair of a diaphragmatic hernia-related small intestinal strangulation in a neonatal foal. A nine-day-old foal presented with colic signs and respiratory distress. History taking showed that the dam of the foal experienced difficulty during delivery, and the owner assisted in delivery by pulling on the foal. Radiography and ultrasonography confirmed the diaphragmatic rent and the presence of a small intestine within the thoracic cavity. Surgical intervention was required to repair the diaphragmatic defect and address the intestinal strangulation. The diaphragm was reconstructed, and the nonviable incarcerated portion of the small intestine was resected and anastomosed using an end-to-end technique. This unusual case report provides insights into the surgical repair and outcomes of an acquired diaphragmatic hernia in a neonatal foal.

Background: The incidence of colic and the outcomes of colic surgery have not been surveyed in racetracks in Korea. Objectives: This study examined the incidence, mortality, and case fatality of colic and investigated the effects of age and sex after an exploratory celiotomy on the long-term survival rate (return to racing), subsequent racing performance, and career longevity. Methods: The incidence, mortality, and case fatalities of colic were examined over an 11-year period. The records of 40 horses that had undergone a celiotomy, after participating in at least one race and 75 race-matched control horses were analyzed. The racing performance and career length of the horses that returned to racing post-surgery were compared with a control group. Results: The annual incidence, fatality rate of colic, and annual mortality rate at Seoul Racecourse were 6.5, 2.8 per 100 horse-years, and 0.2 deaths cases per 100 horse-years, respectively. Of the 40 horses that underwent colic surgery, 26 (65%) returned to racing. The likelihood of returning to racing decreased with increasing age of the horses, and geldings had a lower probability of returning. While the performance in the five preoperative races between the two groups was not significantly different, a significant decrease in racing performance was observed after the surgery date (p < 0.01). Horses that underwent colic surgery did not show a significant decrease in career length. Conclusions: Surgical treatment for colic at the age of three and four years had a negative impact on the racing performance. On the other hand, there was no significant difference in career longevity between the two groups.

A 10-year-old gelding Warmblood weighing 560 kg was referred to J&C Equine Hospital with the history of hyperpnea, depression, pawing, and rolling for 7 hours. According to the results of clinical and ultrasound examination, it was considered that intestines were distended with thickened wall. The horse had been treated with lactated Ringers' solution (14 L, IV), flunixin meglumine (1.1 mg/kg, IV), and mineral oil (1 L, PO), but he did not show any responses to those treatments. Exploratory laparotomy was performed and identified incarcerated small intestine through the epiploic foramen. The horse received resection and anastomosis of the entrapped small intestine. After surgery, the horse was treated with intensive postoperative care of fluid therapy (5 L with 20 mEq/L KCl, every 2 hours), flunixin meglumine (1.1 mg/kg, IV, sid), antibiotics (penicillin 22,000 IU/kg, IV, qid and gentamicin 6.6 mg/kg, IV, sid), lidocaine constant rate infusion (bolus 1.3 mg/kg over 15 minutes then 0.05 mg/kg/minute), common nutritional supplements, nasogastric intubation every 2 hours and trunk bandage. Postoperative feeding program had started with small amount of hay every 4 hours and gradually increased to normal amount till 5 days. At 77 days after surgery, he showed sudden outbreak of colic and was euthanized. The causes of colic were small intestinal strangulation by passing through the mesenteric rents and postoperative adhesion between small intestines. According to the results, it is recommended to perform perioperative intensive care of horse with colic and to use several methods to prevent adhesions during abdominal surgery of horses.

A 3-year-old female Thoroughbred racehorse was presented following the accidental oral and skin administration of amitraz. This case report describes the clinical signs and the treatment of this horse. Clinical signs of amitraz toxicosis are associated with the stimulation of alpha2-adrenergic receptors. Amitraz is seldom fatal because the effects can be reversed by alpha2-adrenergic antagonists. The horse displayed typical clinical signs of colic, including pawing, small hard drops, tranquillisation, depression, ataxia, muscular incoordination and impaction colic lasting up to 7 days. The syndrome was accompanied by mild dehydration. The horse survived after persistent symptomatic treatment, including the giving of intravenous fluids, antibiotics, multiple doses of mineral oil per os, nonsteroidal anti-inflammatory drugs and dexamethasone intramuscularly and intravenously.

An 11-year-old thoroughbred post-partum broodmare presented with the symptoms of colic. The physical and clinical examinations indicated a large colon displacement or volvulus. Immediate surgical intervention was performed, and a strangulating large colon volvulus (LCV) was defined as a volvulus of >540° in the counterclockwise direction. After correcting and assessing the gut viability, approximately 80% of the entire large colon was resected and anastomosed using an end-to-end technique. With supportive care after surgery, the horse regained its appetite and vitality without significant clinical complications and was discharged on postoperative day 9. This report presents the first surgical correction using a large colon resection and anastomosis (LCRA) and the critical care for a strangulating LCV in a horse in Korea. This case enhances the current knowledge of clinical LCV and the related considerations for treatment.

A 3-day-old Appaloosa colt was examined because of acute onset of ataxia, left-sided head tilt, fever and heart murmur. The foal continued to nurse but became increasingly depressed and mild colic. On plain radiological examination, the foal was normal. Uroperitoneum was diagnosed following abdominocentesis. Postmortem examination revealed bladder rupture. The lesion was in the dorsomedial part of the bladder wall. We suggested that the cause of bladder rupture was parturient trauma. Even though the rupture was associated with trauma, the margin of rupture of bladder was clearly smooth and regular.
