The goals of surgical therapy in foal gastroduodenal ulcer disease are the elimination of abdominal pain, healing of mucosal ulcerations, and prevention of complications. Gastrojejunostomy has been used with success in both pyloric and duodenal ulcerations that have progressed to gastric outflow obstruction. Gastrojejunostomy has resulted in rapid healing of gastritis and esophagitis and resolution of aspiration pneumonia and biliary stasis without recurrence of duodenal ulceration.  相似文献

A 2-month-old Warmblood colt presented with recurrent colic and regurgitation. Gastroscopy, performed on several occasions, and barium-contrast radiography revealed severe squamous gastric ulceration and stenosis at the level of the margo plicatus. Treatment with omeprazole reduced the extent and severity of the gastric ulcers but did not affect the stenosis. The foal was euthanised because of a poor prognosis, and post-mortem examination confirmed the clinical diagnosis. Severe squamous gastric ulceration, granulation tissue formation and cicatrisation of deep gastric lesions were considered to have caused the stenosis. Gastroduodenal outflow obstruction is a recognised disorder in foals, but stenosis at the level of the margo plicatus has not been reported in foals or adult horses. To the authors' knowledge, this is the first case of severe squamous gastric ulceration, complicated by stenosis at the level of the margo plicatus, in a foal. Although rare, gastric stenosis should be considered in foals suffering recurrent colic and regurgitation.  相似文献

The objective of the study was to describe a modified Heineke–Mikulicz pyloroplasty for the treatment of pyloric stenosis in foals due to gastric ulceration and assess the short- and long-term outcome of foals receiving the pyloroplasty. Medical records of foals undergoing a modified Heineke–Mikulicz pyloroplasty due to gastric outflow obstruction secondary to a pyloric stenosis were included in this retrospective case series. The pyloroplasty consisted of an oral to aboral full thickness longitudinal incision on the ventral aspect of the pylorus and proximal duodenum, which was sutured closed with 0 polydioxanone in a transverse orientation, thereby, enlarging the pyloric lumen diameter. Long-term outcome was obtained from medical and race records. The pyloroplasty was successfully performed in three foals with a surgical time of 95–121 min, with immediate return to nursing and hospital stay of 4–14 days. Complications included a small intestinal volvulus and intra-abdominal adhesions in a foal that did not survive. Another foal had an incisional infection. Two of the three foals went on to race. It was concluded that the pyloroplasty procedure is an acceptable option for the treatment of pyloric stenosis and secondary gastric outflow obstruction due to gastric ulceration. The limited amount of bowel manipulation with no change in intestinal flow, along with the successful outcomes achieved, make this another surgical option available for the correction of pyloric stenosis in foals.  相似文献

An Arabian foal with a congenital heart disease died due to hemorrhage secondary to a large gastric ulcer. Previously, death of foals with gastric ulcers has been due to diffuse peritonitis resulting from gastric ulcer perforation. The foal in this case report died due to hemorrhage secondary to a large gastric ulcer.  相似文献

Ulcerative duodenitis in foals   总被引：3，自引：0，他引：3  
Seven foals aged 18 days to 3 1/2 months had either single or multiple full-circumference segments or long antimesenteric bands of necrotizing duodenitis, sharply delineated from adjacent viable duodenum. Perforation of the necrotic wall had occurred in all foals, leading to acute fibrinous peritonitis. On the mucosal surface severe diffuse, acute inflammation and ulceration involved the anterior half of the duodenum. Two further foals, aged 28 and 30 days, had lesions that are believed to be a chronic form of this disease. Both foals had a thickened duodenal wall, with large areas of mucosa replaced by granulation tissue. In addition one had several strictures associated with firm adhesions between the duodenal serosa and adjacent structures, together with ascending cholangiohepatitis and pancreatitis. Eight foals had gastric ulcers that were considered to be of less significance than the duodenal lesions. No etiologic agent could be found by aerobic or anaerobic bacterial culturing, negative contrast electron microscopy for viruses, or immunofluorescence staining for equine herpesvirus 1, equine adenovirus, or equine coronavirus. The possible involvement of non-steroidal anti-inflammatory drugs is discussed.  相似文献

A 2-month-old foal was presented with clinical signs of colic. Gastroduodenal ulceration was suspected. A poor response to medical treatment and signs of gastroduodenal obstruction led to celiotomy and an attempted bypass procedure. The foal was euthanized and postmortem examination revealed gastric ulceration, segmental duodenal stenosis, and severe chronic cholangiohepatitis and pancreatitis.  相似文献

Thirteen foals that ranged in age from 4 days to 4 months were presented for treatment of gastroduodenal obstruction. The site of obstruction was determined from examination of standing right lateral contrast radiographs of the caudal part of the thorax and abdomen. Depending on the site, the obstruction was bypassed by esophagogastrostomy, gastroduodenostomy, partial gastrectomy with gastroduodenostomy, duodenojejunostomy, or gastrojejunostomy followed by jejunojejunostomy. Six of the 13 foals (46%) survived. All foals with pyloric stenosis survived. Seven of eight foals with duodenal stenosis died. Deaths were due to complications unrelated to the primary gastroduodenal obstruction.  相似文献

Gastrointestinal diseases of foals   总被引：1，自引：0，他引：1  
Few foals escape gastrointestinal disease during the first weeks of life. Diarrhea is an extremely common problem; fortunately, however, it is usually mild and self-limiting. When it is not, the underlying cause is often an infectious agent, such as rotavirus or Salmonella spp. Our understanding of many of the infectious agents causing neonatal diarrhea is far from complete. Gastric and duodenal ulcers are a less common disease of neonatal foals. There has been an apparent increase in the incidence of ulcer disease in foals during the past few years. The most effective way of decreasing serious gastrointestinal disease in foals is through the use of good management practices. Environmental and dietary stress must be minimized, and good hygienic practices should be followed. Unfortunately, the needs of the neonate are often ignored, while attention is focused on the mare during the breeding season.  相似文献

Reasons for performing study: It has been suggested that the success of gastric bypass surgery in foals for the treatment of gastric outflow obstruction is poor. However, few reports exist evaluating the long‐term prognosis of these cases. Objectives: To determine the long‐term success of foals, including racing records, surgically treated for gastric outflow obstruction secondary to gastroduodenal ulceration. Methods: Medical records of foals undergoing surgical treatment of gastric outflow obstruction secondary to gastroduodenal ulceration were evaluated for clinical information. Owners, trainers and race records were evaluated regarding long‐term survival and racing success. Results and conclusions: Sixteen foals were included in the study, all treated with a gastrojejunostomy. All foals survived to immediate discharge from the hospital; 8 survived to racing age, with 7 of those entering training and 3 actually racing. Foals that did not survive to racing age had various post operative complications. The success rate for these foals appears somewhat better than that previously reported. Potential relevance: Gastrojejunostomy for the treatment of gastric outflow obstruction, secondary to gastric ulceration, is a valid treatment option for foals.  相似文献

Chronic flunixin meglumine therapy in foals   总被引：2，自引：0，他引：2  
Effects of a therapeutic dose of flunixin meglumine on gastric mucosa of horse foals were determined by endoscopy, double-contrast radiography, and gross and histologic examinations. Foals were administered 1.1 mg of flunixin meglumine/kg of body weight, PO/day for 30 days in an encapsulated form that was divided into 2 doses/day (group 1; n = 3) or by IM injection once a day (group 2; n = 7). Three control foals (group 3; n = 3) were administered capsules (n = 1) containing dextrose powder or IM injections (n = 2) of vehicle solution without flunixin meglumine. All 3 groups-1 foals given flunixin meglumine PO developed oral ulcers. Group-2 foals given flunixin meglumine IM did not develop oral ulcers. One control foal (group 3) developed 1 oral ulcer that healed during the study. Endoscopic examination revealed linear crease-like mucosal lesions in the glandular portion of the stomach in 2 group-2 foals. Radiographic evidence of gastric ulcers was observed in only 1 gastrogram of a group-1 foal. Foals were euthanatized, and necropsy revealed erosions and/or ulcers of the glandular portion of the stomach. Oral ulcers were observed in all 3 group-1 foals. Erosions of the glandular portion of the stomach developed in all 10 foals given flunixin meglumine, but did not develop in group-3 foals. Ulceration of the glandular portion of the stomach was present in 1 group-2 foal.  相似文献

Gastroscopic examinations were performed in 62 Thoroughbred broodmares (33 pregnant, 29 non-pregnant) at one breeding farm to investigate the prevalence of gastric ulceration. Age, pregnancy status, race earnings, last race start, herd size, medical history, number of live foals, breeding years, feed type and number of feedings were recorded, plus coat condition and body condition score were determined. Twenty-one mares were re-evaluated after foaling, and the foaling date, foal weight at birth and placenta weight were recorded.The overall prevalence of gastric ulcers was 70.9%, with a median ulcer score of 3.0 (range: 2–5). Most ulcers were present on the squamous portion of the stomach, while two mares had glandular ulcers. There were no differences in the presence, location and severity of gastric ulcers between pregnant and non-pregnant mares. Furthermore, there were no significant associations between the variables measured and the presence of gastric ulceration. The prevalence of gastric ulceration in this specific population of horses was higher than expected and further investigation is warranted to determine the factors that contributed to this finding.  相似文献

Measurement of serum immunoglobulins in 46 foals less than 2 weeks old revealed 9 foals with hypogammaglobulinemia. The hypogammaglobulinemia was attributed to failure in transfer of immunoglobulins from dam to foal via colostrum. Three of the affected foals did not nurse at all, or only slightly, and 2 of these died of infections within a few days after birth, whereas the 3rd foal did not grow as well as normal foals. Six of the affected foals nursed in an apparently normal manner, and 5 of these had nonfatal respiratory infections between 2 and 5 weeks of age. Analysis of serum samples from surviving foals demonstrated that immunoglobulins were eventually produced. One other foal examined had hypogammaglobulinemia at 57 days of age, an age when the foal should have produced large amounts of immunoglobulin independent of passive transfer. This foal had simultaneous infections and hypogammaglobulinemia, but eventually produced normal amounts of immunoglobulin. Cellmediated immunity was normal at 3 months of age. This condition was designated transient hypogammaglobulinemia and was thought to be due to a temporary inability to make immunoglobulins.  相似文献

Chronic gastroesophageal reflux disease was diagnosed in a 22-year-old female Tennessee Walking Horse that had signs of bruxism and ptyalism. Esophageal ulceration was detected via endoscopy. Compared with the damage to the proximal portions of the esophagus, the severity of the ulceration increased toward the gastroesophageal junction. Esophageal ulceration attributable to chronic gastric acid reflux is usually secondary to pyloric outflow obstruction in horses. In the horse of this report, there was no evidence of either a chronic pyloric or duodenal obstruction that could have resulted in esophageal ulceration. Esophageal ulceration in this horse was attributed to gastroesophageal reflux disease, a common condition in humans in which the underlying abnormality is functional incompetence of the gastroesophageal junction. Treatment is directed at decreasing gastric acidity and protecting the ulcerated mucosa. In the horse of this report, treatment was unsuccessful and the horse was euthanatized; a physical cause of gastroesophageal reflux disease was not identified during an extensive postmortem examination.  相似文献

Third-degree perineal lacerations or rectovestibular fistulae in 17 mares were repaired surgically by a one-stage method. Primary healing occurred in 14 mares; there were one complete dehiscence and two partial dehiscences with fistula formation. Twelve of 13 mares that were bred became pregnant; nine carried foals to term and two are still pregnant. Two mares have each produced one unthrifty foal. One mare repeatedly aborts in the first trimester. Four mares have produced several healthy foals with no further problems. One mare suffered further perineal trauma while foaling.  相似文献

Gastroduodenal ulceration is a prevalent disease in foals and adult horses. Decreased performance as well as fatal complications relate to this syndrome. The objective of our study was to determine the prevalence of gastric ulceration in a mixed population of horses by postmortem examination and to evaluate a possible association between equine gastric ulcer syndrome (EGUS) and sex or age of the examined horses, to evaluate the localisation of lesions in the proximal part of the gastrointestinal tract and to determine the occurrence of gastric parasites. Postmortem examinations were performed on 71 horses over a period of 24 months. Gastric ulcers were found in 52 horses (73.2%). There was no significant association between age or sex and occurrence of gastric ulcers. In all horses the squamous mucosa lesions were localised near the margo plicatus (100% of the cases), whereas in 23 horses the lesions were near the margo plicatus and lesser curvature and in 7 horses at the greater curvature. In 18 horses the mucosa was affected in the whole extent of the margo plicatus and in 1 horse diffuse lesions of the squamous mucosa were noted. Lesions of the glandular mucosa were localised in 11 horses at the fundic area, in 1 horse they occurred in the pylorus, and in 10 horses diffuse lesions of the glandular mucosa were recorded. A low prevalence of Gasterophilus intestinalis infection was detected (1 horse, 1.4%). We have confirmed that gastric ulcers are a common problem in horses and duodenal or oesophageal ulceration is rare (not a single case of the latter was found in this study). Lesions in the glandular mucosa of the stomach are more frequent in suckling foals than in older animals. Lesions of the glandular mucosa are also common in adult horses, and a complete gastroscopic examination including examination of the pylorus is advisable to evaluate this syndrome.  相似文献

The extensive nature of this topic warrants this review paper to be divided into two parts: ‘Routine basic trimming in foals’ and ‘Therapeutic farriery in foals’. Hoof care in the first few months of life is serious business and should never be taken lightly. Good farriery is vital for the development of the hoof capsule and the conformation of the limb. Management of the feet and limbs during the juvenile period will often dictate the success of the foal as a sales yearling or mature sound athlete. Overall hoof care of a foal is often a joint venture between the veterinarian and the farrier. Part 1 of this paper will outline the concept of a footcare programme, examination of the foal's feet and limbs along with what constitutes good basic farriery to properly apply the trim. It will also emphasise the importance of maintaining a good veterinarian-farrier relationship - the farrier being responsible for basic trimming with veterinary oversight when necessary, and if orthopaedic disorders develop, the farrier will have significant input with therapeutic farriery.  相似文献

Objective— To report short- and long-term survival and factors affecting outcome of foals after surgical correction of gastric outflow obstruction.
Study Design— Case series.
Animals— Foals (n=40) aged 5–180 days.
Methods— Clinical signs, laboratory data, diagnostic imaging, surgical findings, surgical procedures, medical treatment, and necropsy findings were retrieved from medical records. Outcome was obtained by reviewing performance, sales, and produce records or by telephone conversations with the owners.
Results— Gastric outflow obstruction was treated by gastroduodenostomy or by gastrojejunostomy with or without jejunojejunostomy. Long-term follow-up was available for 36 of 39 foals that survived to hospital discharge; 25 (69%) survived >2 years. All 8 foals with pyloric obstruction survived >2 years, whereas only 11 of 21 (52%) foals with duodenal obstruction survived >2 years. Six of 8 foals with obstruction of the duodenum and pylorus survived >2 years. Obstruction of the duodenum, adhesions to the duodenum, and postoperative ileus were significantly associated with decreased long-term survival.
Conclusions— Long-term outcome after gastric bypass procedures was substantially improved compared with previous reports. Factors that may have contributed to improved survival include better case selection and performing the gastrojejunostomy with the jejunum aligned from left to right.
Clinical Relevance— The prognosis for long-term survival after surgical bypass of pyloric obstruction is excellent. The overall prognosis for long-term survival after surgical bypass of duodenal obstruction is fair but should be considered guarded in those with pre-existing duodenal adhesions.  相似文献

Femoral neck and proximal epiphyseal lengths were measured in 37 femurs from 19 cadaver foals that were 1 day to 12 months old to determine the applicability of a human interfragmentary compression system to equine femoral capital physeal fractures. Because components of the implant system are available only in fixed sizes, its use was possible in foals older than 5 weeks of age, but not in younger foals. The 135 degree angle plate conformed best to the equine femur. Femoral capital physeal fractures were created surgically and repaired with the implant system in three foals. Fracture stability was evident clinically and radiographically in all three foals until euthanasia at month 3. At necropsy, the treated femurs were 4, 8, and 27 mm shorter than their mates. Epiphyseal viability was verified in all three foals by tetracycline deposition and new appositional bone growth comparable with that in the contralateral control epiphyses. The treated capital physis was open but reduced in thickness in one foal, disorganized in one foal, and closed in one foal. Fixation by compression with the implant system resulted in stability sufficient for fracture healing and maintenance of epiphyseal viability, although it was associated with reduced longitudinal femoral growth.  相似文献

OBJECTIVE: To determine whether foal management practices, environmental management, and preventative health practices are risk factors for development of Rhodococcus equi pneumonia in foals. DESIGN: Prospective matched case-control study. ANIMALS: 2,764 foals on 64 equine breeding farms with 9,991 horses. PROCEDURE: During 1997, participating veterinarians completed paired data collection forms for comparison; 1 for an affected farm (containing > or = 1 foal with pneumonia caused by R equi) and 1 for a control farm. Information collected pertained to stabling facilities, environmental management, foal husbandry, and preventative equine health practices. RESULTS: Matched farm data compared by use of conditional logistic regression indicated that personnel on affected farms were more likely to attend foal births, test foals for adequacy of passive immunity, administer plasma or other treatments to foals to supplement serum immunoglobulin concentrations, administer hyperimmune plasma prophylactically to foals, vaccinate mares and foals against Streptococcus equi infection, and use multiple anthelmintics in deworming programs. Affected farms were also more likely to have foals that developed other respiratory tract disorders and were approximately 4 times as likely to have dirt floors in stalls used for housing foals as were control farms. CONCLUSIONS AND CLINICAL RELEVANCE: Rhodococcus equi pneumonia does not appear to be associated with poor farm management or a lack of attention to preventative health practices. Housing foals in stalls with dirt floors may increase the risk for development of R equi pneumonia.  相似文献
