The present study was conducted in 18 cows, divided into three groups (I,II and III ) of six animals each based on the type of internal obstructive lesion viz; focal (Type I), diffuse (Type II) and membranous (Type III) respectively. The location and morphometry of the obstructive lesion was confirmed by ultrasonographical examination. Axial theloscopy of the teat was performed to visualize the nature, location and extent of lesion. Theloscopic electroresection was performed by cutting of the obstructive lesion at 70-800 c and coagulating at 80-900 c was performed and 50- 90 % of the mass could be resected from all the teats which was confirmed by ultrasonography. Intramammary infusion through the prosthetic tube kept insitu and systemic antibiotic were administered for 5 days. The procedure improved the milkability without any recurrence till 30th day postoperatively. | Theloscopic and ultrasonographical evaluation of internal teat obstruction in cows and its treatment using video assisted theloscopic electro resection
