title: ["Emergency splitting" of the teat canal--a therapeutic procedure in case of concurrent occurrence of acute thelitis and severe mastitis].
abstract: In case of concurrent acute thelitis and severe mastitis, an immediate surgery of the stenosis ("emergency splitting") might be justified in order to improve milkability as a prerequisite for the removal of pathological milk secretion and therapy, successful mastitis therapy. The aim of this study was to compare the milkability and the clinical cure rate of mastitis between Group A (n = 19, cows with stenosis, thelitis and mastitis) and Group B (n = 19, cows with stenosis, with or without clinical mastitis, but without acute thelitis) following surgery of the papillary duct using a cutting instrument (Danish cannula model with a double cutting edge). In most cases, milkability was restored at the end of the treatment in both groups (Group A: 89.5%; Group B: 100%). In this time period nine of 19 quarters with mastitis in Group A were clinically cured (47%). Six month after the surgery, the animal owners considered the milkability as very good in 70% and 72% of the cases in Group A and Group B, respectively. However, "emergency splitting" led to a more intensive and longer postsurgical treatment. The average duration of total treatment (day of surgery plus 6 days of obligate postsurgical treatment plus additional treatment days) was 7.4 and 6.7 days in Group A and Group B, respectively. Furthermore, the higher expenditure was due to the more costly mastitis therapy. During the six month following surgery, only one cow of Group A had to be culled due to persistent mastitis and two cows because of insufficient milkability.
