Introduction:
Twenty days old indigenous male bovine calf having body weight 40 kg presented with the complaint of swollen umbilical contents at Veterinary Teaching Hospital, Bangladesh Agricultural University, Mymensingh, Bangladesh. Physical examination confirms the case is an evisceration of umbilical content with extensive adhesion which is not much common in the bovine calf (Figure 1). All the other clinical parameters were found normal, which confirmed the calf was free from another infectious disease.
Umbilical herniorrhaphy was done where electrocauterizer was used to incise the eviscerated tissue, which contains the part of the small intestine and also to minimize the bleedings. All the contents were put back in the abdominal cavity. Finally, the ring, muscle and skin were sutured separately (layer by layer) with polyglactin 910 (No. 1-0), catgut (No. 1-0) and nylon (No. 1) (Figure 2), respectively. Along with the surgical process, administration of antibiotic, antihistamine, anti-inflammatory medication was done, and proper hygenic management was suggested. Now the calf is healthy and doing well.
The evisceration of the intestine may occur spontaneously after gradual worsening of the hernia and thinning of the wall, or it may be abruptly caused by trauma or sudden straining. [1] With the timely surgical intervention and proper hygenic management of umbilical hernia, the outcome is generally good, otherwise recurrence or secondary infections may be seen as the chance of bacterial infection is high in male calves because of their anatomical structures. [2-3]
