Diaphragmatic herniorrhaphy without positive pressure ventilation in buffaloes

Twenty-two clinical cases of diaphragmatic hernia in buffaloes were presented with the history of recurrent tympany, partial or complete off feed for long time and wasting body condition. Diaphragmatic hernia was tentatively diagnosed based on clinical signs and by auscultation of reticular sound at the level of 6^th rib at right side of thoracic cavity, which was confirmed by exploratory rumenotomy and repaired by herniorrhaphy through trans-abdominal approach under xylazine sedation and local infiltration anaesthesia with high success rate (77.77%) without using positive pressure ventilation. In field conditions diaphragmatic herniorrhaphy may be performed successfully without positive pressure ventilation and general anaesthesia in unilateral cases.
