Unilateral mastectomy as an alternative treatment for gangrenous mastitis in a Saanen goat

Abstract

A four-year-old Saanen goat, weighing 52 kg, was referred to the Department of Obstetrics and Gynaecology clinic with black discoloration of the left mammary gland. The goat's general condition was not good upon initial examination. The goat was anorexic, lethargic, and febrile (rectal temperature of 40°C) with a palpably cold left mammary gland on which there was an accumulation of pus. Somatic cell count (SCC) was measured as 820,000/ml in the milk sample collected from the infected gland, and Staphylococcus aureus was isolated. Gangrenous mastitis was diagnosed on the left mammary gland of the goat based on the clinical findings. To treat the condition, a unilateral mastectomy was performed successfully. The goat was fully recovered a week after surgery. This case aimed to establish a surgical approach of unilateral mastectomy as a treatment option for goats with gangrenous mastitis while allowing the other mammary gland to continue lactation. Thus, it can be concluded that unilateral mastectomy is a viable alternative treatment of goats with gangrenous mastitis. ª 2015 Faculty of Veterinary Medicine, Cairo University.

Distinguishing the milk microbiota of healthy goats and goats diagnosed with subclinical mastitis, clinical mastitis, and gangrenous mastitis

“…Generally, this type of mastitis is associated with the agents Staphylococcus sp. ( Peer and Bhattacharyya, 2007 ; Sabuncu et al, 2015 ), Escherichia coli ( Ameh et al, 1994 ), Bacillus sp. ( Mavangira et al, 2013 ) or by co-infection of bacteria ( Ribeiro et al, 2007 ).…”

“…( Rainard et al, 2018 ). In addition, it is a serious clinical condition, leading to the loss of milk production capacity, mastectomy, culling, and high lethality ( Abu-Samra et al, 1988 ; Peer and Bhattacharyya, 2007 ; Ribeiro et al, 2007 ; Sabuncu et al, 2015 ; Rainard et al, 2018 ). In this study, we detected an association between Escherichia sp./ Shigella sp.…”

Mastectomy in 25 small ruminants (2002‐2019)

“…Large surgical defects after radical mastectomy are typical 3,7 . Other authors have recommended second intention healing after resections of large tumors because of the lack of skin available for closure 3,5 . One of the authors of this study (A.N.B.)…”

“…3,7 Other authors have recommended second intention healing after resections of large tumors because of the lack of skin available for closure. 3,5 One of the authors of this study (A.N.B.) has extensive experience with the inverted cloverleaf surgical technique for radical mastectomy in small ruminants.…”

“…Mastectomy has previously been performed in ruminants by mammary vascular ligation for gangrenous mastitis with and without amputation of the teat, total mastectomy with elliptical incisions around the udder and primary closure, unilateral (partial) mastectomy, and the inverted cloverleaf skin incision pattern for radical (total) mastectomy. [3][4][5][6][7][8] Total mastectomy in ruminants most commonly involves elliptical incisions around the udder. 1,4,7 Skin closure after radical mastectomy can be difficult to achieve without excessive tension.…”
