Topic:Duodenitis
Duodenitis in horses refers to the inflammation of the duodenum, which is the initial segment of the small intestine immediately following the stomach. This condition can result from various causes, including infections, dietary factors, or the use of certain medications. Clinical signs may include abdominal discomfort, changes in appetite, and alterations in bowel movements. Duodenitis can affect the digestive efficiency and overall health of the horse. This page gathers peer-reviewed research studies and scholarly articles that explore the causes, pathophysiology, diagnostic approaches, and management strategies for duodenitis in equine species.
Geographic Disparities in Clinical Characteristics of Duodenitis-Proximal Jejunitis in Horses in the United States. Duodenitis-proximal jejunitis (DPJ) is an idiopathic and potentially fatal disease of horses characterized by abdominal pain, proximal intestinal inflammation, and subsequent gastric and small intestinal fluid accumulation. Although this disease is known to be costly and life threatening in the equine industry, the severity of clinical signs can vary widely, and an exact etiology has yet to be elucidated. This study looked to identify differences in clinical parameters of horses with DPJ between geographic regions in an effort to corroborate anecdotal reports and support theories of differing ...
Complications and survival associated with surgical compared with medical management of horses with duodenitis-proximal jejunitis. Based on clinical observation, it is hypothesised that horses with duodenitis-proximal jejunitis (DPJ) that are treated surgically have a shorter duration, smaller volume, and slower rate of nasogastric reflux (NGR) compared to horses treated medically, are more likely to develop diarrhoea than medically managed cases, and have a higher incisional infection rate than a sample population of horses undergoing abdominal exploration for gastrointestinal disease other than DPJ. Objective: To compare: 1) duration, volume and rate of NGR and the percentage of horses with diarrhoea between medically a...
Potential role of Clostridium difficile as a cause of duodenitis-proximal jejunitis in horses. Duodenitis-proximal jejunitis (DPJ) is an idiopathic condition in the horse characterized by inflammation and oedema of the duodenum and proximal jejunum. Clinical signs include colic, ileus, depression, fluid accumulation in the small intestine and stomach, and endotoxaemia. The objective of this study was to investigate prospectively the role of Clostridium difficile in this idiopathic disease. Nasogastric reflux from 10 consecutive cases with DPJ and 16 consecutive horses with other causes of nasogastric reflux was cultured for C. difficile, other Clostridium spp., and Salmonella. Toxigenic...
Prognostic indicators for horses with duodenitis-proximal jejunitis. 75 horses (1985-1989). The medical records of 75 horses with duodenitis-proximal jejunitis (DPJ) were reviewed. Ages, physical parameters, laboratory values, and treatment data were compared between horses surviving DPJ and horses not surviving DPJ (Table 1). Fifty of 75 horses (66.6%) survived. Sixty-six horses (88.0%) were managed with medical treatment alone and nine horses (12.0%) were managed with medical treatment plus surgical intervention. Using a logistic regression model, the association of each of the 19 physical and laboratory parameters with death was evaluated retrospectively in the 75 horses. Three pa...
Cardiac arrhythmias identified in horses with duodenitis/proximal jejunitis: six cases (1985-1988). During a 3 1/2-year period, cardiac arrhythmias were identified in 6 of 67 horses diagnosed with duodenitis/proximal jejunitis (DPJ). Arrhythmias were detected by auscultation of irregular cardiac rhythm and subsequently were characterized by electrocardiographic evaluation. Arrhythmias included frequent second-degree atrioventricular block, ventricular ectopic depolarizations, and atrioventricular conduction disturbance. In 4 horses, arrhythmias resolved with recovery from the primary problem. One horse died suddenly 66 hours after admission, and another was euthanatized at 72 hours after adm...
Comparison of duodenitis/proximal jejunitis and small intestinal obstruction in horses: 68 cases (1977-1985). Sixty-eight horses with colic caused by small intestinal disease were allotted into 2 groups of 34 on the basis of recorded findings during exploratory celiotomy, necropsy, or response to medical treatment alone. Signalment, history, physical examination findings, and laboratory findings were compared between the group of horses with small intestinal obstruction and the group with duodenitis/proximal jejunitis. A significantly greater proportion of horses with duodenitis/proximal jejunitis were older than 2 years old (P less than 0.05). Differences in sex or breed distribution, or in seasonali...
Traumatic duodenitis with subsequent thrombosis of the posterior vena cava in a horse. The possible sequelae of traumatic perforation
of the reticulum of cattle are described by Blood
and Henderson (1963). Traumatic splenitis and
hepatitis following perforation of the reticulum
have also been described in detail (Blood and
Hutchins 1955).
Frank (1959) described and illustrated both
thrombus formation and stricture of the posterior
vena cava following traumatic reticulitis with subsequent abscess formation. The proximity of the
abscess to the posterior vena cava apparently
caused erosion of the vessel wall, and the inflammatory reaction initiated the formation of a
thr...
