Abstract
The present study was carried out to evaluate the extrinsic prognostic factors viz. environmental temperature, duration of illness, stage of pregnancy/calving and intraoperative variables i.e. hernial ring size, extent of herniation, presence of potential foreign bodies, adhesions, time duration of restraint of buffaloes in different recumbencies and total time taken for surgery. A comparison of these factors was made in the surviving and non-surviving animals. It was found that a longer duration of illness (more than 30 days) and greater dehydration increased the surgical risk. Higher ambient temperature accounted to thermal stress. Large hernial ring size (H – 19.81±1.79 cm; W – 22.41±5.66 cm) and greater percentage (50-70%) of reticulum herniation accounted for poor survivability. Herniation of other organs such as liver and spleen along with multiple foreign bodies and adhesions lead to greater mortality. Longer duration of surgery with greater period for which thoracic cavity was opened associated with a longer duration in dorsal recumbency proved fatal for the animals. Besides these, concurrent intraoperative complications such as regurgitation, apnoea and rupture of herniated organs were responsible for poor outcomes following diaphragmatic herniorrhaphy. The study was suggestive that a cascade of factors was responsible in determining the prognosis of buffaloes undergoing diaphragmatic herniorrhaphy and proper steps taken to counter these factors shall greatly reduce the mortality in chronic life-threatening affections.
