Clinical Presentation, Surgical Treatment, and Outcome of Traumatic Patellar Luxation in 11 Dogs and 5 Cats: A Single-Centre Retrospective Study between 2011 and 2022.

OBJECTIVE: Patellar luxation (PL) is commonly diagnosed in dogs and cats; however, a traumatic cause is poorly reported in the literature. The aim of this study was to report the clinical presentation, surgical treatment, and outcome in dogs and cats surgically treated for traumatic PL. STUDY DESIGN: This is a retrospective study. Medical records of dogs and cats operated for traumatic PL were reviewed. Short- and long-term follow-ups were assessed with medical records and telephone interviews with owners and referring veterinarians. Data on signalment, lameness, PL characteristics, surgery, complications, and outcome were recorded. RESULTS: Eleven dogs and 5 cats were included. Both species had a median lameness grade of 4/5 and a median PL grade of 3/4. PL was medial in most cases (13/16). Joint capsule lesions were identified in 15 cases, 4 cases had trochlear ridge cartilage damage. All cases had a capsular imbrication, 12 cases had a fabello-patellar suture (FPS). Mean long-term follow-up time was 70.8 ± 42.5 months in 9 dogs and 4 cats. Ten cases out of 13 had no lameness at the 2-month follow-up, and 11/13 cases had no long-term lameness. Eleven cases out of 13 had no PL at the 2-month follow-up. No long-term PL was reported by owners. Complications were mild in 5 cases, moderate in 1, severe in 3. Functional outcome was full in 10 cases and acceptable in 3. CONCLUSION: Soft tissue techniques and FPS were effective in the surgical treatment of traumatic PL in dogs and cats, resulting in acceptable to full long-term function in all cases, with limited severe complications.

Septic peritonitis secondary to intra-peritoneal grass awn migration: 7 cases (2014-2021).

Objectives: To describe the clinical presentation, management, and outcome of cases treated for septic peritonitis secondary to intra-peritoneal grass awn migration. Animals: Six client-owned dogs and 1 client-owned cat. Procedures: Clinical data of dogs and cats treated surgically for septic peritonitis secondary to an intra-peritoneal grass awn identified during surgery between January 2014 and December 2021 were retrospectively reviewed. Data included signalment, clinical presentation, blood test results, diagnostic imaging findings, surgical procedure, postoperative complications, and outcome. Telephone interviews were conducted for long-term follow-up. Results: Six dogs and 1 cat met the inclusion criteria. The most common reported clinical signs were lethargy (n = 7), anorexia/dysorexia (n = 4), and pyrexia (n = 4). The vegetal foreign body was not identified in any case with ultrasound (0/5) and only suspected for one case with a computed tomography scanner (1/4). A grass awn was identified within an omental abscess for each case during surgery. Abscess resection for each case resulted in partial pancreatectomy and a splenectomy for 1 case, and partial gastrectomy for another case. All cases survived to discharge. Only one minor post-operative complication was identified, and no other complication was reported at the long-term telephone interview. Conclusion and clinical significance: Septic peritonitis secondary to omental grass awn foreign body is an uncommon condition that has a good to excellent prognosis after surgical treatment. Identification of omental grass awn with ultrasound and computed tomography is rare. Therefore, particular care should be given to omental exploration during surgery for septic peritonitis with no underlying cause identified.

Péritonite septique secondaires à la migration de barbes de graminées : 7 cas (2014-2021). Objectifs: Décrire la présentation clinique, la prise en charge et pronostic des chiens et chats traité pour une péritonite septique secondaire à la migration intrapéritonéale d'un corps étranger végétal. Animaux: Six chiens et un chat traités. Protocole: Les informations des dossiers des chiens et chats pris en charge chirurgicalement pour une péritonite septique pour lesquelles un corps étranger végétal intrapéritonéal a été identifié entre janvier 2014 et décembre 2021 ont été obtenues. Les données concernant le signalement, la présentation clinique, les analyses sanguines, les examens d'imagerie, les procédures chirurgicales, les complications post-opératoires et l'évolution post-opératoire ont été collectées. Le suivi à long terme a été réalisé par téléphone. Résultats: Six chiens et un chat ont été inclus dans l'étude. Les signes cliniques les plus fréquents rapportés sont l'apathie (n = 7), l'anorexie/dysorexie (n = 4) et l'hyperthermie (n = 4). Les corps étrangers végétaux n'ont été identifiés dans aucun cas par échographie (0/5) et suspectés dans un cas à l'examen tomodensitométrique (1/4). Les corps étrangers ont tous été identifiés au sein d'un abcès dans l'omentum en chirurgie. Une résection de l'abcès a été réalisée dans chaque cas associé à une pancréatectomie partielle et une splénectomie pour un cas et une gastrectomie partielle pour un autre cas. Tous les animaux ont survécu. Seule une complication mineure a été rapportée en post-opératoire et aucune autre complication n'a été rapportée lors des entretiens téléphoniques. Conclusion et portée clinique: Les péritonites septiques secondaires à des migrations intra-péritonéale de corps étrangers végétaux sont des affections rares qui semblent être associées à un pronostic de survie bon à excellent après prise en charge chirurgicale. L'identification des corps étrangers dans l'omentum est difficile par échographie ou examen tomodensitométrique. Par conséquent, une attention particulière doit être portée à l'exploration de l'omentum lors de prise en charge chirurgicale de péritonite septique sans cause sous-jacente identifiée.(Traduit par les auteurs).

Comparison of computed tomography and surgical findings and investigation of their associations with outcomes for dogs with sublumbar abscesses.

OBJECTIVE: To describe and compare the results of preoperative CT and surgical findings in dogs with sublumbar abscesses and investigate potential associations between these variables and the outcome of abscess recurrence. ANIMALS: 51 client-owned dogs. PROCEDURES: A retrospective, records-based study was performed of dogs undergoing surgery for treatment of sublumbar abscesses diagnosed by use of CT between January 2010 and December 2018. Signalment, clinical signs, clinicopathologic data, CT findings, surgical techniques and findings, duration of hospitalization, postoperative treatment, and complications were recorded. Long-term follow-up was performed through telephone interviews. Logistic regression analysis was used to investigate associations between the variables of interest and abscess recurrence. RESULTS: 51 dogs met the study inclusion criteria; 48 were included in outcome analysis. The CT findings agreed with surgical findings for identification of a migrating vegetal foreign body for 39 of 51 (77%) dogs. All dogs survived to hospital discharge; 1 dog died of hemoabdomen 3 days after surgery, and 6 had minor (surgical wound) complications reported. Abscess recurrence developed in 12 of 48 (25%) dogs with a median time to recurrence of 6 months. Identification of diskospondylitis on CT examination was the only investigated factor significantly associated with recurrence; odds of recurrence in dogs with this finding were 8.4 times those for dogs without this finding. CONCLUSIONS AND CLINICAL RELEVANCE: Our results suggested dogs with sublumbar abscesses have a good prognosis after surgery, although recurrence can develop. Preoperative identification of diskospondylitis was significantly associated with abscess recurrence in this study sample.
