Abstract
BackgroundThree Brown Swiss cows with abnormal regurgitation because of a perioesophageal disorder are described.Case presentationThe cows were ill and had poor appetite, salivation and regurgitation of poorly-chewed feed. Collection of rumen juice was successful in one cow, and in another, the tube could be advanced to the level of the 7th intercostal space, and in the third, only saliva could be collected. In one cow, oesophagoscopy revealed a discoloured 10-cm mucosal area with fibrin deposits. Thoracic radiographs were normal. The cows were euthanased and examined postmortem. Cow 1 had a large perioesophageal abscess containing feed material at the level of the thoracic inlet, believed to be the result of a healed oesophageal injury. Cow 2 had an abscess between the oesophagus and trachea 25 cm caudal to the epiglottis with the same presumed aetiology as in cow 1. Cow 3 had a mediastinal carcinoma that enclosed and constricted the oesophagus.ConclusionsAbnormal regurgitation in cattle is usually the result of an oesophageal disorder. Causes of oesophageal disorders vary widely and their identification can be difficult.
Highlights
Three Brown Swiss cows with abnormal regurgitation because of a perioesophageal disorder are described.Case presentation: The cows were ill and had poor appetite, salivation and regurgitation of poorly-chewed feed
While regurgitation is a normal phenomenon in ruminants, abnormal regurgitation is usually the result of an oesophageal disorder, often affecting the intrathoracic part
History and clinical findings Three Brown Swiss cows, which originated from dairy herds with a mean milk yield of 7’800 to 8’500 kg per lactation and ranged in age from six years to nine years, were referred to our clinic because of abnormal regurgitation that had not responded to treatment
Summary
Abnormal regurgitation in ruminants is defined as the discharge of food from the mouth [1] and occasionally from the nose [2] immediately after prehension of feed and before the feed enters the forestomachs. Endoscopic, ultrasonographic and radiographic examination Endoscopic examination (video coloscope, 1680 mm × 11.5 mm, Olympus Schweiz, PCF-Q-180AL) of the trachea of all cows revealed no abnormal findings, and examination of the oesophagus was normal in cows 2 and 3. – 3.8 – 6.0 – 2 to +2 was assumed even though only cow 1 had endoscopic evidence of this This cow received 10 l of a NaClglucose solution (50 g glucose and 9 g sodium chloride/l), administered slowly via an indwelling intravenous catheter daily for three days, amoxicillin (7 mg/kg, Clamoxyl®, Zoetis Schweiz, Zürich) administered intramuscularly for 3 days, and 500 ml of 40% calcium borogluconate (Calcamyl-40MP®, Graeub, Bern) administered once intravenously. In cow 1, massive fibrinous adhesions were seen between the oesophagus and surrounding tissue as well as the trachea and surrounding tissue This area had a large well-encapsulated abscess (Figure 3A) containing feed material (Figure 3B). The postmortem diagnosis was abscess between the oesophagus and trachea, presumably as a result of oesophageal trauma.
