An unusual case of oesophageal obstruction in a female buffalo.

A nine-year-old female graded Murrah buffalo weighing about 420 kg was presented to the clinic with a history of not taking feed and water and sudden development of bloat since the morning. It had calved three months before and had been sent out for grazing daily. The bloat was relieved using 16 G needle at a local hospital but the condition recurred. Clinical examination revealed distended left fl ank. Pulse, temperature and respiration were within normal physiological limits. On passage of a stomach tube, an obstruction was felt at the thoracic region anterior to the diaphragm. It was tentatively diagnosed as oesophageal obstruction, and it was decided to relieve the obstruction through rumenotomy, as thoracotomy in ruminants requires special equipment, and the procedure is a diffi cult one.
