Sialolithiasis in horses: A retrospective study of 25 cases (2002-2013).

Abstract: This study evaluated outcomes of surgical treatment of equine sialolithiasis, highlighting cases involving the proximal parotid salivary duct. Sialoliths in the proximal parotid duct were difficult to identify radiographically and more frequently associated with draining tracts and sialadenitis compared with sialoliths in the distal parotid duct. Ultrasonography confirmed the diagnosis of sialolithiasis in all cases in which there was no radiographic evidence of a sialolith. All cases of proximal parotid duct sialolithiasis required transcutaneous removal. A longer duration of illness was observed in cases of proximal parotid duct sialolithiasis compared with cases involving the distal parotid duct, and in cases requiring transcutaneous removal compared with cases requiring transoral removal. Recurrence of sialolithiasis was documented in 24% of cases, all of which were located in the distal parotid duct. The average time to recurrence was 2.8 years. Cette étude a évalué les résultats du traitement chirurgical de la sialolithiase équine et a mis en lumière des cas touchant le canal salivaire parotidien proximal. Les sialolithes du canal de Sténon étaient difficiles à identifier par radiographie et sont plus fréquemment associés à des faisceaux de drainage et à la sialadénite par opposition à des sialolithes dans le canal de Sténon distal. L’échographie a confirmé le diagnostic de sialolithiase dans tous les cas où il y avait des preuves radiographiques d’un sialolithe. Tous les cas de sialolithiase du canal salivaire parotidien proximal ont exigé une ablation transcutanée. Une plus longue durée de la maladie a été observée dans les cas de sialothiase du canal salivaire parotidien proximal par opposition aux cas touchant le canal de Sténon distal et, dans les cas exigeant l’ablation transcutanée par opposition aux cas exigeant l’enlèvement transoral. La récurrence de la sialolithiase a été documentée dans 24 % des cas et ils étaient tous situés dans le canal salivaire distal. Le délai moyen avant la récurrence était de 2,8 ans.(Traduit par Isabelle Vallières).

This research paper looks at the outcomes of surgical treatment for sialolithiasis, a condition where stones form in the salivary glands of horses. It also focuses on cases involving the proximal parotid salivary duct, stressing the difficulties in diagnosis and the higher rate of complications.

Objective of the Study

  • The study was conducted to evaluate the outcomes of surgical treatment of equine sialolithiasis, which is a condition characterised by stone formation in the salivary glands of horses.
  • The particular focus was on cases that involved the proximal parotid salivary duct, a specific part of the horse’s salivary system.

Findings of the Study

  • The study discovered that sialoliths lodged in the proximal parotid duct were challenging to identify through radiographs. They were also more likely to be associated with draining tracts and sialadenitis (inflammation of the salivary glands) compared with sialoliths located in the distal parotid duct.
  • Ultrasonography was effective in confirming the diagnosis of sialolithiasis in cases where there was no radiographic evidence of a sialolith.
  • All cases of proximal parotid duct sialolithiasis required transcutaneous removal, whereby the sialoliths were removed through the skin rather than via the mouth.
  • Longer illness durations were seen in cases involving proximal parotid duct sialolithiasis than in cases affecting the distal parotid duct.
  • Around 24% of the study cases experienced a recurrence of sialolithiasis and these were all found in the distal parotid duct. Average time to recurrence was approximately 2.8 years.

Implications of the Study

  • These findings provide vets with valuable knowledge on diagnosing sialolithiasis, especially in cases involving the proximal parotid duct.
  • The strong association found between proximal parotid duct sialoliths and inflammation suggests a need for careful observation and possibly enhanced treatment protocols in such cases.
  • The fact that all such cases required transcutaneous removal also provides vets with insights on the most likely course of treatment required.
  • Longer illness durations and high recurrence rates pointed out in the study underscore the need for long-term management and monitoring plans for horses diagnosed with sialolithiasis.
