Abstract
The research work was carried out to study the incidence, clinical signs,
haematobiochemical changes, endoscopic findings in cattle with oesophageal disorders
and to evaluate the effect of sedation on oesophagus in cattle. Twelve apparently
healthy cattle were randomly selected to obtain normal oesophagoscopic images along
with data of parameters under study. Thirty seven cattle with oesophageal disorders
formed the clinical group and were subjected to detailed anamnesis, clinical
examination, haemato biochemistry, radiographic and endoscopic evaluation of
oesophagus. Incidence of oesophageal disorder in cattle was 2.47 per cent of the
various medical disease conditions. Salient clinical signs noticed in oesophageal
disorders were salivation, tachypnoea, bloat, regurgitation with extended head and
neck, cough, tachycardia, dysphagia and swelling on left side of the neck. Cattle with
oesophageal foreign body had highly significant elevation of mean packed cell volume
and serum creatine phosphokinase value while there was leucocytosis with neutrophilia
in cattle with oesophageal dilatation when compared to that of respective control mean.
In cattle with oesophageal dilatation, there was dilatation of oesophagus either in the
cervical and / or thoracic part in plain radiograph and retention of barium in the dilated
oesophagus in contrast oesophagogram of cervico-thoracic region. In animals with
oesophageal foreign body, soft tissue opacity was seen within the oesophagus
contrasted by gas. On oesophagoscopy of apparently healthy cattle, oesophageal
mucosa appeared light pink coloured, smooth and glistening with submucosal vascular
pattern. The oesophagus had longitudinal mucosal folds and were closed together to
appear like a star. Upon insufflations with air, the folds got separated and the cardia
appeared as a slit. In cattle with oesophageal dilatation, oesophagoscopy revealed
dilated oesophagus with feed and / or water and absence of linear folds. Various
oesophageal foreign bodies observed during the study period include beetroot, tapioca,
cabbage, bone piece, linear rusted iron piece, rope, guava, orange, fish hook, mango
and phytobezoar. Majority of the foreign bodies were noticed in the cervical
oesophagus. Increased vascularity of submucosal vessels, mucosal ulcers or
haemorrhage was noticed through oesophagoscopy in cattle with oesophagitis.
