Retrospective evaluation on the outcome of perineal herniorrhaphy augmented with porcine small intestinal submucosa in dogs and cats.

The purpose of this study was to evaluate post-operative outcome in dogs and cats undergoing perineal herniorrhaphy using porcine small intestinal submucosa (PSIS) alone and with internal obturator muscle transposition augmented with PSIS (IOMT + PSIS). Medical records were retrospectively reviewed and information collected on signalment, pre-operative signs, operative details, and hospitalization. Data on post-operative outcome were obtained from medical records and survey. Eleven dogs and 3 cats had 18 perineal hernias repaired with IOMT + PSIS and 3 using PSIS alone. Surgical site infection developed following IOMT + PSIS in 1/21 hernias (5.6%). Short- and long-term postoperative complications occurred in 9/14 animals and 3/14 animals, respectively. Among the 21 perineal hernias, 3 recurred, 2 of which were repaired with IOMT + PSIS and 1 with PSIS alone. Use of PSIS alone or augmenting IOMT was acceptable for perineal herniorrhaphy and should be considered by surgeons if there are concerns about internal obturator muscle integrity.

Évaluation rétrospective de l'issue d'hernioraphie périnéale renforcie avec de la sous-muqueuse du petit intestin de porc chez des chiens et des chats. Le but de la présente étude était d'évaluer l'issue postopératoire chez des chiens et des chats soumis à une hernioraphie périnéale utilisant de la sous-muqueuse du petit intestin de porc (PSIS) seule et avec transposition du muscle obturateur interne renforcie avec PSIS (IOMT + PSIS). Les dossiers médicaux furent révisés rétrospectivement et les informations amassées sur le signalement, les signes préopératoires, les détails opératoires et l'hospitalisation. Les données sur l'issue postopératoire furent obtenues des dossiers médicaux et d'un sondage. Onze chiens et trois chats ont eu 18 hernies périnéales réparées avec IOMT + PSIS et trois en utilisant PSIS seule. Une infection du site chirurgical se développa à la suite de l'utilisation de IOMT + PSIS chez 1/21 hernies (5,6 %). Des complications post-opératoires à court et long terme sont survenues chez 9/14 animaux et 3/14 animaux, respectivement. Parmi les 21 hernies périnéales, il y eu une récurrence chez trois, deux qui furent réparées avec IOMT + PSIS et une avec PSIS seule. L'utilisation de PSIS seule ou renforcie avec IOMT était acceptable pour l'hernioraphie périnéale et devrait être considérée par les chirurgiens s'il y a des inquiétudes concernant l'intégrité du muscle obturateur interne.(Traduit par Dr Serge Messier).

Urinary calculi in a shih tzu dog with hyperadrenocorticism.

An 11-year-old spayed female shih tzu dog was presented with pollakiuria, stranguria, and hematuria. Radiographs revealed a large number of radiodense urinary calculi within the bladder. Physical examination, complete blood cell count, biochemistry and ACTH stimulation test suggested possible hyperadrenocorticism. A cystotomy was performed and the patient was treated for hyperadrenocorticism.

Calculs urinaires chez une chienne Shih Tzu atteinte d'hyperadrénocorticisme. Une chienne Shih Tzu stérilisée âgée de 11 ans a été présentée avec de la pollakiurie, de la strangurie et de l'hématurie. Les radiographies ont révélé un grand nombre de calculs urinaires radio-opaques dans la vessie. L'examen physique, une formule sanguine complète et la biochimie ont suggéré la possibilité d'hyperadrénocorticisme. Une cystotomie a été réalisée et la patiente a été traitée pour l'hyperadrénocorticisme.(Traduit par Isabelle Vallières).

Multi-institutional study of long-term outcomes of a ventral versus lateral approach for mandibular and sublingual sialoadenectomy in dogs with a unilateral sialocele: 46 cases (1999-2019).

OBJECTIVE: To compare the long-term outcomes of a ventral versus lateral surgical approach for mandibular and sublingual sialoadenectomy in dogs with a unilateral sialocele. ANIMALS: 46 client-owned dogs. PROCEDURES: Medical records of dogs that underwent unilateral sialoadenectomy between 1999 and 2019 were retrospectively reviewed, and information was collected regarding signalment, clinical signs, historical treatment, swelling location, diagnostic imaging findings, sialoadenectomy approach, adjunctive treatments, intraoperative complications, hospitalization time, postoperative complications, recurrence, and contralateral sialocele development. RESULTS: There were no significant differences in incidences of intraoperative complications, recurrence, or postoperative complications between dogs in which a lateral versus ventral approach was used. Clinically important intraoperative complications included iatrogenic tears in the oral mucosa, ligature slippage from the duct end, hemorrhage, and possible lingual nerve transection. Surgical experience was associated with the likelihood that intraoperative complications would develop. Suspected recurrence was reported in 2 of 26 (8%) dogs that underwent a lateral approach and 2 of 12 (17%) dogs that underwent a ventral approach. Hospitalization time was significantly shorter with the lateral approach than with the ventral approach. Postoperative complications had a short-term onset and occurred in 4 of 25 (16%) dogs that underwent a lateral approach and 3 of 12 (25%) dogs that underwent a ventral approach. Age and presence of a pharyngeal sialocele were associated with development of postoperative complications. CLINICAL RELEVANCE: Long-term outcomes for ventral and lateral approaches to sialoadenectomy were favorable and appeared to be comparable. Further prospective study into potential associations of sialoadenectomy approach, age, and pharyngeal sialoceles on outcome is needed.

Suspected Radiation-Induced Osteosarcoma in a Domestic Shorthair Cat.

A 3-year-old, male neutered domestic shorthair cat, presented for acute onset tail paresis. He was diagnosed with a spindle cell tumour at the level of L7-CD1 and treated with course fractionation radiation therapy. Three years following radiation therapy, the cat developed chondroblastic osteosarcoma of the pelvis, suspected to be secondary to radiation therapy. Hemipelvectomy was performed and the cat was treated with radiation therapy for remaining gross disease. The cat was euthanized 127 days post-operatively due to suspected metastatic disease. Development of radiation-induced tumours should be considered as a rare late complication in cats undergoing radiation therapy.
