(Re)ocurrence of inguinal hernia in case of very large vaginal rings may simply be prevented by closure of the vaginal tunic by TA staples during castration by inguinal approach. This method provides a good resistance to internal pressure, appears to be safe, fast and easy to perform and may therefore be an interesting alternative to laparoscopic techniques when castration is considered.

Mechanoreceptors are “encapsulated sensory end-organs” involved in proprioceptive function. Given the high incidence of meniscal injuries in horses, the clinical interest in these mechanoreceptors, particularly in the meniscus, and the lack of information concerning them in equine menisci, our objective was to study these corpuscles in the anterior horn of the equine medial meniscus, which is the most common localization reported for equine meniscal injuries. An immunohistochemical approach to detect Schwann cells and nerve fibres allowed us to localize and identify these corpuscles within the meniscus. Three types of mechanoreceptors were identified and localized between the abaxial quarter and the abaxial third of the meniscus: the Ruffini, Pacini and Golgi corpuscles. In conclusion, from a purely fundamental point of view, our work highlights for the first time the presence of MCR at the level of the anterior horn of the equine medial meniscus and proposes a classification based on specific immunocytochemical techniques. This morphological approach could serve as a basis for clinical studies, in order to evaluate the impact of these corpuscles on the poor sportive prognosis in equine meniscal tears. [less ▲]

The objectives of this study were to describe and relate perioperative changes in blood leukocyte counts to the outcome of surgical colic horses, determine a cut-off value in the early postoperative period to obtain an indicator of the outcome, and compare the obtained value to a validation population of horses. Fifty-three horses undergoing colic surgery were included in the descriptive part of the study. Total leukocyte counts were performed before, during and serially after surgery. A receiver operating characteristic analysis was performed on the leukocyte counts of 45 of these horses to determine a cut-off value for the outcome. The results obtained were validated on a second set of 50 horses that underwent colic surgery in similar conditions. The kinetics of blood leukocytes in survivors was higher than in non-survivors during the first days. Non-survivor horses were more likely to have at least one blood leukocyte count ≤3.9×103/mm3 between 28 and 60 hours after surgery than survivor horses. This cut-off value was confirmed in the validation population. These results suggest that routine values of blood leukocyte counts can be used as an additional prognostic indicator after colic surgery alongside other predictors previously associated with the outcome.

Aims: To evaluate the prognosis of horses treated surgically for open joint injuries. Methods: The medical records of horses admitted for surgical treatment of a wound in communication with a joint were reviewed. A telephone questionnaire was used for the long term evaluation. Fisher’s exact tests were used for the statistical analyses. Results: Twenty two horses were included in the study with the following distribution of lesions: 6 carpi, 6 fetlocks, 4 tibiotarsal joints, 2 proximal and 3 distal interphalangeal joints, 1 elbow. The duration of the injury before referral ranged from 3 hours to 10 days. Surgical treatment consisted of 1-3 joint lavages. Of the 22 horses, 4 were euthanatized during hospitalization and 18 were discharged. After discharge, 3 horses died due to colic, 2 were lost and 13 were still alive. The survival was not influenced by the duration of the wound. All horses with cutaneous defects less than 5 cm and all horses affected in the lower limb (below the level of the canon) were discharged. Having an affected joint proximal to the canon was significantly associated to the need of multiple surgeries (OR: 17.5; p= 0.024). Conclusions: Even if the prognosis remains guarded for open joint injuries, a long delay between injury and treatment should not be systematically associated with a bad prognosis for survival. Open joint injuries of the lower limb were associated with survival. They required less often multiple articular lavages than open joint injuries of the upper limb, warranting thus a better prognosis. [less ▲]

Introduction: Les kératomes, masses hyperplasiques de kératine, croissent entre la phalange distale (P3) et la paroi du sabot et provoquent des boiteries chez le cheval. La littérature comporte de nombreux rapports de cas isolés mais peu de séries cliniques. Matériel et méthodes: Les dossiers cliniques des cas de kératomes présentés depuis 2004 à la faculté de médecine vétérinaire de Liège ont été revus. Résultats: Vingt-trois kératomes ont été diagnostiqués sur 19 chevaux boiteux. Un cheval présentait 2 kératomes sur le même pied et 3 chevaux présentaient 2 kératomes sur des pieds différents. Sur les 22 pieds atteints, les lésions observées étaient: un abcès, souvent récidivant (18 cas), une déformation de la muraille (6 cas), une déviation de la ligne blanche (6 cas) et une seime (3 cas). Un kératome était situé sous la sole et 22 sous la muraille. La durée des symptômes variait de 2 semaines à 15 ans (plus d'un an sur 12 pieds). Sur les radiographies, une lyse par compression de P3 était visible en regard de 20 kératomes. Le cheval présentant 2 kératomes sur le même pied a été euthanasié. Trois kératomes ont été traités de manière conservative. Dix-huit kératomes (chez 16 chevaux) ont été excisés chirurgicalement dont 16 par avulsion complète de muraille, 1 par avulsion partielle de muraille et 1 par curetage d'une portion de sole. Aucune complication postopératoire n'a été observée dans 7/18 cas (39%). Les complications rencontrées étaient: une granulation excessive (10 cas), une douleur importante pendant plusieurs jours (5 cas), une légère infection (4 cas), un enfoncement de P3 en regard de la zone avulsée (2 cas) et une récidive (2 cas, dont 1 a été réopéré avec succès ultérieurement). Un cheval est encore en convalescence au moment de cette étude. Le suivi à long terme d’un cheval a été perdu. Des 14 chevaux repris dans l'évaluation postopératoire, 1 a été euthanasié pour une autre raison que le kératome, 3 chevaux ont gardé une boiterie résiduelle au trot et 10 chevaux ont récupéré leur niveau d'activité. Discussion: La littérature décrit les kératomes comme rares1. Or, 21% des chevaux de cette étude (4 chevaux sur 19) présentaient plusieurs kératomes. De plus, dans 54 % des cas, les symptômes duraient depuis plus d’un an. Dès lors, il apparait que les kératomes sont sous diagnostiqués ou le sont souvent tardivement. La chronicité et l’étendue des kératomes de cette étude n’a que très rarement permis leur résection par avulsion partielle de muraille, technique de choix dont les complications postopératoires sont moindres². Un diagnostic précoce par inspection minutieuse des sabots, particulièrement en cas d’abcès de pied récidivant permettrait une excision par une technique moins invasive, qui diminuerait la convalescence et les complications postopératoires.

Les plaies traumatiques ou chirurgicales nécessitent souvent une cicatrisation par seconde intention lorsque la fermeture primaire n’est pas possible ou échoue. La fermeture assistée par le vide (Vacuum Assisted Closure : VAC) est une méthode active et non invasive qui expose le lit de la plaie à une pression sub-atmosphérique locale afin de promouvoir sa cicatrisation. Elle stimule la granulation et la perfusion sanguine locale et réduit significativement l’œdème et la charge bactérienne.1 Cette technique s’est révélée efficace dans le traitement des plaies aiguës et chroniques chez l’homme. Chez le cheval, la méthode est encore peu décrite.2,3 Nous rapportons ici l’application et les effets de la thérapie des plaies par pression négative à travers les cas traités à la clinique vétérinaire universitaire de Liège depuis 2010. Les plaies étaient chirurgicalement débridées avant l’application du système VAC. Une mousse en polyuréthane était appliquée après avoir été adaptée à la géométrie de la plaie. Un champ plastique adhésif était alors apposé sur la plaie pour créer un environnement hermétique et un orifice d’1 cm2 était créé au centre du système pour appliquer la ventouse du tuyau d’aspiration. Cette ligne était alors raccordée à l’appareil d’aspiration contrôlée pour maintenir une pression continue de -125 mmHg dans la plaie. Quinze cas ont été recensés: 3 plaies intra-articulaires (au carpe, au coude et au grasset), 3 sur la face dorsale du canon postérieur, 2 sur la face dorsale du jarret, 1 sur la pointe du calcanéum, 2 sur l’encolure et 4 plaies de laparotomie infectées. Le traitement a accéléré la croissance du tissu de granulation, stimulé la contraction des plaies et favorisé la cicatrisation dans la majorité des cas (12/15). Les plaies apparaissaient aussi plus saines et présentaient moins de sécrétions lors des changements de bandages. Des résultats plus modérés ont été notés chez les 3 autres cas. Quelques complications mineures comme des irritations cutanées ont été observées. Le traitement de plaies contaminées nous a orientés vers l’usage d’une mousse de polyuréthane argenté mais d’autres types de matrice sont disponibles et permettent de modifier le comportement de la plaie. L’usage d’une mousse de polyvinyl Alcool s’est ainsi avéré efficace pour améliorer l’adhésion des greffons lors d’une greffe de peau chez le cheval.3 La principale limite du traitement réside dans la difficulté technique de maintenir la plaie sous vide lors d’atteinte de régions très mobiles comme les articulations. En conclusion, le système VAC semble très prometteur pour optimiser la qualité de la cicatrisation et réduire la durée de l’hospitalisation. 1 - Morykwas, M.J., Argenta, L.C., et al.

Introduction Squamous cell carcinoma (SCC) has been occasionally reported in the equine pharyngeal region1-3. The aim of this poster is to describe imaging findings in 4 cases of pharyngeal SCC. Material and methods Four old horses, mean age 19.5, 2 females and 2 geldings, were referred for dyspnea (3/4) and/or dysphagia (3/4). Because of dyspnea radiographs were realized prior to endoscopy. Ultrasound (US) was performed in all cases by ventral and lateral approach using a linear 7,5MHz transducer. A post-mortem computed tomography (CT) of the head was performed in one case (16 slices CT, Somatom 16, Siemens). Results Radiographic opacity of the pharyngeal region was increased in all cases. A soft tissue mass was also visible in the caudal maxillary sinus in 1 horse. The epiglottis was either not recognized or difficult to see with an abnormal shape. Pharyngoepiglottic distance and nasopharyngeal diameter were reduced in all cases. The soft palate was either thick or impossible to be outlined, with an irregular surface. In 1 case it was dorsally displaced. The dorsal pharyngeal wall looked unevenly thickened or impossible to be outlined ventrally due to border effacement. No bony damage was identified on radiographs. A hypoechoic heterogeneous mass was visualized at US in 2 cases and an enlargement of the mandibular lymph nodes was observed in 3 cases. Lymphnodes had also heterogeneous echogenicity and increased doppler signal in 1 case. Oral and pharyngeal endoscopic examination confirmed a pharyngeal mass in 2 cases but was unsuccessful or incomplete because of passage impairment in 2. CT revealed maxillary bone lysis in the horse with a mass in the maxillary sinus. Histopathological examination of local biopsies or necropsy revealed pharyngeal SCC invading epiglottis, pharyngeal wall and soft palate in the 4 horses and the maxillary sinus in one. Discussion/Conclusion Because endoscopy can be impaired by the size of the mass, radiology is helpful in estimating the extent and invasiveness of the process and US to confirm lymphadenopathy. However because of its relatively low sensitivity and the local increased opacity, radiographic examination may underestimate bone lysis. [less ▲]

Background: Despite the recent advances in this area, colic remains a major cause of morbidity and death in horses. Neutrophilic activation and degranulation may play a key role in the postoperative complications. Activated neutrophils release enzymes like proteases and myeloperoxidase (MPO). MPO concentrations in plasma and tissue are considered as a marker of neutrophil activation. (McConnico et al. 1999; Hoy et al. 2002). When freed in the tissue, active MPO is able to oxidize, nitrate and chlorate most organic molecules (Klebanoff 2005). Objectives: The aim of this study was 1) to determine the time trends of blood leukocyte and neutrophil counts as well as of plasmatic MPO concentrations in the perioperative period of horses undergoing colic surgery and 2) to relate these time trends to the location of the pathology, the severity of postoperative complications and to the outcome of the patients. Methods: Fifty two horses undergoing colic surgery at the Equine Teaching Hospital of the University of Liege were included in this study. The location of the predominant lesion of the intestine, the severity of the postoperative complications and the outcome were recorded for each horse. Total leukocyte and neutrophil counts were performed in all of the horses while plasmatic myeloperoxidase levels were determined in 16 of them. The blood samplings were realized before and during the surgery (after correction of the intestinal lesion), during the recovery and every 4 hours during the first 4 days (from day 0 until day 4) and then every 12 hours until day 6 (150th hour after the first blood sampling) or until euthanasia. Hematologic analyses were performed at the time of sampling by use of the Medonic CA 530 (Menarini, Zaventem, Belgium). The blood was then centrifuged and the plasma was aliquoted and frozen at -20° C until assayed. MPO was assayed with a specific enzyme-linked immunosorbent assay (Equine MPO-ELISA kit, BiopTis, Liège, Belgium). A mixed model was used to analyze the time trends of leukocytes, neutrophils and MPO. All computations were done with the SAS (Statistical Analysis System) procedure Proc Mixed, with Satterthwaite degrees of freedom. The significance level was set at p=0.05. Results: The main pathology was found in the large intestine in 30 horses (58%) and the small intestine in 22 horses (42%). Forty horses (77%) survived to discharge from the clinic. Twelve horses were euthanized during the postoperative period. Their survival time varied from 0.5 day to 20 days with a mean of 7.8 days. Twenty-two horses (42%) showed none or mild complications, 12 horses (23%) showed moderate complications and 18 horses (35%) suffered from severe complications. Time trends for leukocytes and neutrophils were similar to each other (p= 0.7205) and significantly different (p< 0.0001) from the MPO time trend, which increased during the first hours, while the neutrophil time trend decreased immediately after the admission. The time trend of neutrophils was higher in large intestinal than in small intestinal pathologies and the time trend of MPO was lower in large intestinal than in small intestinal pathologies. The time trends of neutrophils were significantly different between the degrees of complications (no/mild vs moderate vs severe). For the first part of the curve, the more severe the complication, the lower is the time trend. The time trend of MPO was lower in survivors. The time trend of neutrophils in survivors was higher during the first 4 days thereafter it becomes lower than in non survivors. Conclusions: These results confirm that neutrophil counts and MPO levels undergo timely changes and that they are related to the severity of the inflammatory reaction in surgical colic cases. Knowing the kinetics of these parameters is an essential step to further determine cut-off values (with a larger group of horses) for the prognosis of horses after colic surgery.

ultrasonography is currently more and more used in equine acute abdominal disease as well as in the follow-up of surgical colic patients because of its sensibility for the detection of small intestinal distension. General anaesthesia is known to diminish gastrointestinal motility even if there are no clinical signs associated with it. The aim of this study was to evaluate the effect of general anaesthesia on transabdominal ultrasonographic images of the small intestine in horses undergoing routine non abdominal surgeries. The ultrasonographic exams were performed in 19 horses before and after the general anaesthesia (immediately after the recovery and then 2h, 12h and 24h after it). Each ultrasonographic exam focused on the duodenum, the jejunum and the presence of peritoneal fluid. For the jejunum, 5 locations were used: on the ventral midline just caudally to the sternum, on the left and right cranial ventral parts of the abdomen, on the left and right inguinal regions. Other parameters such as the gut sounds and the postoperative fecal output were also recorded. Anova and Chi-square tests were used for the statistical analysis. No horse showed colic signs. No significant difference was found between the pre and post anaesthetic period considering the maximal diameter of the duodenum, the maximal diameter of the jejunum on the 5 locations and the peritoneal fluid. The contractions of the duodenum were increased at the recovery compared to before the anaesthesia (p= 0,0299). The small intestine was most visible at the recovery (57,5%) and then at 2 hours after it (38,3%). It seemed that the ventral midline just caudally to the sternum and the right and left inguinal regions were the best locations to observe the jejunum (with a mean of respectively 44,6%, 39,8% and 38,5% of visualization of the jejunum).The gut sounds were very significantly decreased at the recovery (p < 0,0001) and at 2h after it (p = 0,0006). The postoperative fecal output was not decreased. In conclusion, even if general anaesthesia seems to reduce temporarily the intestinal activity (decreased gut sounds in the early post anaesthetic period), it does not cause significant distension of the small intestine (almost the small intestinal diameters were in the normal range). If an increased diameter of small intestine is observed by ultrasonography after surgery it should therefore be attributed to a pathological process and not to the anaesthesia. [less ▲]

Recent evidence shows hydro-alcoholic solutions are more efficient than traditional medicinated soaps in the presurgical hand antisepsis of human surgeons. However, little veterinary literature is available on the subject. The aims of this study were to compare the efficiency of medicinated soaps and a hydro-alcoholic solution prior to surgery using an in use testing method in a veterinary setting. A preliminary trial was performed that compared the mean Log10 number of bacterial colony forming units (CFU) and the reduction factors (RF) between 2 five-minute hand-scrubbing sessions using different soaps (povidone iodine (PVP) and chlorhexidine gluconate (CHX)) and the 1.5-min application of a hydro-alcoholic rub (Sterillium). A clinical in use trial comparing mean log10 number of bacterial CFU’s and RF for Sterillium and CHX soap was performed in a surgical set-up. Sampling was performed using finger printing on agar plates. Sterillium and CHX had a similar immediate effect, although the sustained effect was significantly better for Sterillium. PVP showed a significantly lower immediate and sustained effect. Sterillium showed good efficiency in the clinical trial. This study shows that, as previously reported for human medicine, Sterillium can safely be considered as an attractive alternative method for surgical hand antisepsis in a veterinary surgical setting.

Objective: To assess current habits for surgical hand preparation amongst veterinary surgical specialists and to compare data with current guidelines for hand asepsis techniques. Study design: Survey of veterinary surgical specialists Sample Population: Diplomates of the American (ACVS) and European Colleges of Veterinary Surgeons (ECVS). Methods: An internet based survey of hand preparation methods before surgical procedures was conducted of 1300 listed ACVS and ECVS Diplomates. Results: A 42.6% response rate was obtained. Approximately 80% of respondents use disinfecting soaps as a primary method for hand antisepsis. Of those, 81% use chlorhexidine based scrubs and 7% use a neutral soap followed by a hydroalcoholic solution. Conclusions: Contrary to current recommendations of the World Health Organization and scientific evidence supporting use of hydro-alcoholic rubs for presurgical hand preparation, veterinary surgical specialists still use surgical scrub solutions containing disinfecting soaps.

Introduction: Despite the fact that presurgical antiseptic hand treatment of surgical staff has since become a worldwide accepted procedure, surgical site infection is still one of the most frequent types of nosocomial infections. Many products have been used for hand antisepsis, but the popularity of alcoholic rubs amongst human surgeons is increasing as they have shown to provide a rapid and immediate action, are considerably faster than disinfecting soap scrubs and cause less skin damage after repeated use. The purpose of this study was 1) to identify surgical hand antisepsis habits amongst veterinary surgery specialists in Europe (ECVS) and the United States (ACVS), 2) to compare povidone iodine and chlorhexidine gluconate scrubs with a hydro-alcoholic rub hand antisepsis protocol and 3) to evaluate the usefulness of a hydro-alcoholic rub solution in a veterinary surgical setting. Materials and Methods: Emails were sent to 1300 Diplomates to invite them to participate to an online survey in order to obtain an idea about pre-surgical hand disinfection techniques. In a preliminary trial the efficiency of 4% chlorhexidine gluconate, 7.5 % PVP-iodine and an alcoholic solution containing 45% 2-propanol, 30% 1-propanol, 0.2% mecetronium ethylsulphate (Sterillium®) in bacterial reduction on hands was compared. In a clinical trial, the suitability of Sterillium® was assessed in an equine and small animal set up during surgery procedures. Fingertips were pressed on blood agar plates and Gassner plates prior to hand antisepsis (PHA), after handantisepsis (AHA) and three hours after wearing sterile gloves (AG) in the preliminary trial or at the end of surgery (AS) in the clinical trial. Bacterial counts (colony forming units : CFU’s) were obtained after 24 h of incubation of the plates. The obtained values of CFU from PHA, AHA, AG and AS were expressed as log10 values. For each sample, a reduction factor (RF) was obtained from the difference of log10 pre-value and log10 post-value. An ANOVA comparison between the effects of the different antisepsis protocols on the mean log10 CFU values and RF’s in function of the different steps was established. Results: A 42.6% response rate was obtained for the survey. Most surgeons’ still use a disinfecting soap only (79.9%) for hand antisepsis prior to surgery, the majority based on chlorhexidine gluconate (81.4%). Significant differences were found between immediate and sustained activities of the different products tested. Sterillium® was shown to have significantly lower LSM log10 CFU at AG compared to both other products. At AHA, povidone iodine revealed to have significantly higher LSM log10 CFU than Sterillium® and chlorhexidine gluconate, with the last two products having comparable activities. Reduction factors for the Sterillium® were significantly greater than for the other products. Only RF1 was comparable between Sterillium® and chlorhexidine gluconate. In the clinical trial, no significant differences were found between surgeons regarding LSM log10 CFU after hand antisepsis, neither between RF from samples taken at the small animal versus the equine surgery theatre. Discussion: This study confirms that Sterillium® is more effective in reducing bacterial counts on hands prior to surgery in a veterinary setting as are chlorhexidine gluconate (CHX) and povidone iodine soap. Moreover, they provide better tolerance and compliance to surgical hygiene protocols. Despite this, veterinary surgeons from all over the world still prefer the use of CHX soap, which has far more disadvantages than commonly accepted. Apart from the better skin tolerance and the absence of known resitance to the product, the use of Sterillium® offers the advantage of a fast (1.5 minute) surgical handantisepsis. This study shows that, as previously reported for human medicine, Sterillium® can safely be used in a veterinary surgical setting. [less ▲]

Equine neutrophil elastase (NE) is a protease released in inflammatory diseases and participating in tissue destruction. To measure NE in horse plasma to assess its role in pathological conditions, we purified elastase from equine neutrophils by a double step chromatography and obtained a pure protein of 27kDa, 4kDa smaller than the NE 2A previously purified (Scudamore et al., 1993; Dagleish et al., 1999), which was likely to be NE 2B. We developed an ELISA by using two specific polyclonal antibodies obtained from rabbit and guinea pig. The sandwich complex was detected using a secondary antibody conjugated to alkaline phosphatase. The ELISA showed good precision and accuracy, with intra- and inter-assay coefficients of variation below 10% for equine NE concentrations ranging from 1.875 to 60ng/ml. A stable plasma NE value, unaffected by the delay of centrifugation (over 4h), was obtained with plasma from EDTA anticoagulated blood. The mean value (+/-SEM) measured in 37 healthy horses was 32.53+/-4.6ng/ml. NE level in plasma of horses with colic at the time of admission was significantly higher than in healthy horses. Our results indicate that the ELISA technique we developed to measure plasmatic NE is a powerful tool for studying the role of elastase in equine inflammatory disease. In future, the application will be extended to other equine biological fluids. [less ▲]

Lesions to the horse’s tendon are very frequent and are a non negligible reason for early retirement of sport and leisure horses. For decades man has been searching for “the” treatment but unfortunately most of the known treatments have empiric bases and very few have actually proven their real efficiency. Diagnostic techniques like ultrasound allows to better evaluate the improvements made in tendonitis therapies. Stem cells and gene therapy are probably the most innovating of them, but their long-term effectiveness still has to stand the test of times. This article gives an overview of the possible treatments of tendonitis today. [less ▲]
