Parotid duct transposition in dogs: a retrospective review of 92 eyes from 1999 to 2009

Abstract

This study shows that PDT is a successful procedure based on clinical findings and in terms of owner perception. It has also demonstrated that PDT improves ocular comfort and vision in medically refractive cases of keratoconjunctivitis sicca, and that a low level of on-going management is required in 33% of cases.

Topical applications of allogeneic adipose-derived mesenchymal stem cells ameliorate the canine keratoconjunctivitis sicca

“…Furthermore, a significant number of canine KCS patients do not respond to tear stimulant treatment. For those canine KCS patients which have proven to be refractory to all tear stimulant remain candidates for parotid duct transposition (PDT) surgery [35]. Interestingly, 56.5% of the patients who were unresponsive to prior immunosuppressant therapy showed improved tear volume following cAD-MSCs treatment in this study.…”

Eye removal following parotid duct transposition surgery: A survey of current practice among veterinary ophthalmologists

“…5 There is also a reported case where, due to saliva intolerance, the PDT was successfully reversed to the oral cavity but the eye was not removed at that time. 2 Ligation has also been reported to have resulted in orbital sialocele development in two dogs. 5,6 It should be of note that one of those dogs, a Yorkshire terrier, 8 was also reported in this study.…”

“…No respondents chose sialadenectomy. Also reported via write in response was transection of the duct with no further manipulation (2). Suture reported, via multiple choice, for ligation included nylon (4), polyglactin 910/polyglycolic acid (2) and polydioxanone (1).…”

“…Suture reported, via multiple choice, for ligation included nylon (4), polyglactin 910/polyglycolic acid (2) and polydioxanone (1). One additional suture reported was polypropylene (2). Ligation suture size varied from 4/0 (3), 5/0 (2), 6/0 (2), 3/0 (1), and one unknown.…”

Canine keratoconjunctivitis sicca: an overview

“…A recent retrospective published review carried out by the author showed that although the procedure carries a relatively high complication rate (51%: of which the majority could be managed conservatively) the overall success rate was very high (93%). The study also highlighted that dogs post PDT were generally more comfortable, had improved vision and required less ongoing maintenance (Rhodes et al, 2012).…”
