Teat obstructions cause considerable financial loss in dairy industry. Recently, progress in teat surgery was made by the use of minimal invasive surgical instrumentation. The technique of theloresectoscopy as well as short- and long-term results of this surgical intervention are presented in this study. The clinical reports of 15 dairy cows with distal teat obstructions operated with the theloresectoscope between May 1999 and January 2000 at the clinic for ruminants, Departement of clinical veterinary medicine, University of Berne were reviewed. Data collected by telephone conversation with the owners included: somatic cell count and milk flow at machine milking during the lactation of surgery (lactation 1), as well as during the lactation following surgery (lactation 2). Eightyseven percent of the owners reported normal milk flow during lactation 1 and 93/ during lactation 2. Considering the fact that only 46.7/ of the cows showed negative results in the california mastitis test (CMT) during lactation 1, many owners reported a high somatic cell count being a disadvantage of this surgical technique. Normal (negative) CMT results during lactation 2, however, were reported by 80/ of the owners. Isolation of Staphylococcus aureus explained the high somatic cell count in 2 of 15 cases. In conclusion, theloresectoscopy is a valuable minimal invasive surgical technique that can be fully recommended for treatment of distal teat obstructions in dairy cows.
