NEW STUDY – Exploring a Novel Diagnostic and Treatment Technique in Combination With Surgery for Thyroid Tumours in Dogs
Complete Title: Exploration of Nanoparticle-Enabled Image Exploration of Nanoparticle-Enabled Image Guided Photoblation in Veterinary Patients
PORPHYSOME-enabled therapies can have an immediate impact on cancer management providing better patient outcomes. This study will evaluate the potential applications of the novel nanomedicine (PORPHYSOMES) and PDT in veterinary clinical patients with thyroid tumours.
This project is part of the Veterinary Medical Innovation Platform aligned with Dr Michelle Oblak’s research chair with OVC and Animal Health Partners!
- Dogs with a confirmed freely moveable thyroid tumour interested in pursuing surgery are eligible
NEW STUDY – Evaluation of a Fluorescent dye in Dogs with Hepatobiliary Disease Undergoing Gallbladder Removal Surgery
Complete Title: Evaluation of Indocyanine Green (ICG) Cholangiography in Dogs with Hepatobiliary Disease Undergoing Cholecystectomy
This study aims to determine the clinical usefulness of a safe fluorescent dye (indocyanine green, ICG) in canine patients with hepatobiliary disease scheduled to undergo gall bladder removal surgery by assessing whether it improves visualization of the biliary tree during surgery.
- Any dog undergoing routine gall bladder removal surgery (open or laparoscopic cholecystectomy) during normal operating hours at the OVC
NEW STUDY – Evaluating the Use of Fluorescence Dyes in Surgery to Identify Canine Pancreatic Cancer and Metastasis
Complete Title: Pilot Evaluation of Near Infrared Fluorescence Imaging for Intraoperative Identification of Canine Insulinoma and Their Metastasis
Near-infrared fluorescence imaging (NIRF) using Indocyanine Green (ICG), a fluorescent dye, has been previously used in a number of veterinary applications (many in clinical trials here at OVC). The use of NIRF for pancreatic mass resection in dogs has not yet been described but holds excellent potential for improving patient outcomes. The objective of this pilot study is to investigate the feasibility and utility of NIRF imaging for intraoperative characterization of pancreatic tumours and their metastases in dogs.
- Dogs that are diagnosed with a pancreatic mass and scheduled for exploratory laparotomy
The Use of Fluorescent Dyes to Evaluate Sentinel Lymph Nodes During Surgery for Dogs with Lung Tumours
Complete Title: Evaluation of Sentinel Lymph Node Mapping in Dogs with Lung Tumours using CT Lymphography and Intraoperative Indocyanine Green
The objective of this study is to compare the accuracy of CT and intraoperative identification of sentinel (first draining) lymph nodes in dogs with lung tumours and to develop protocols for these methods of staging.
- Dogs with a single lung tumour (less than 5cm) interested in pursing CT scan and surgery
Comparison of Two Surgical Techniques and Long Term Outcomes to Alleviate Congenital Constriction in Dogs
Complete Title: Prospective, Long-Term Evaluation of Esophageal Function and Clinical Outcome Following Surgical Treatment of Vascular Ring Anomalies (VRA) in Dogs
The objective of this study is to evaluate the long term outcome following surgical treatment of VRA, specifically, objective data regarding clinical outcome and esophageal function.
- Dogs with a confirmed diagnosis of a VRA undergoing CT scan and surgery
Evaluating the Use of Minimally Invasive Surgical Techniques for Dogs Presenting with Spontaneous Pneumothorax
Complete Title: Prospective Evaluation of Minimally Invasive Thoracic Surgery for Identification of Pulmonary Bullae in Dogs with Spontaneous Pneumothorax
The objective of this study is to evaluate the accuracy in identifying bubbles on the lungs during this technique.
- Dogs with a confirmed diagnosis of a spontaneous pneumothorax undergoing traditional open surgery through the breast bone
Analyzing Lymph Node Spread in Dogs Undergoing Surgery for Thyroid Tumours
Complete Title: Evaluation of Regional Lymph Node Metastasis in Canine Thyroid Carcinoma
The objective of this study will provide a more accurate idea of how often metastasis to the lymph nodes occurs in dogs with thyroid tumours or what effect that lymph node involvement has on prognosis. Specialized tissue staining may also help find deposits of cancer beyond routine staining techniques.
- Dogs with a confirmed diagnosis of a thyroid tumour undergoing staging and surgery
Comparing the Use of Fluorescent Dyes in Surgery to Previously Reported Methods for Improving Lymph Node Staging in Dogs with Oral Cancer
Complete Title: Evaluation of Agreement Between Computed Tomography Lymphangiography and The Combination of Methylene Blue and Indocyanine Green for Sentinel Lymph Node Mapping in Dogs with Oral Tumours
The objective of this study is to evaluate the agreement between imaging and intraoperative techniques for identification of Sentinel Lymph nodes (SLNs) in canine patients with oral tumours. Development of these protocols could help decrease the number of lymph nodes surgically removed, in addition to ensuring accurate evaluation of the most important lymph node(s) for making follow-up treatment recommendations improving patient prognosis and outcomes for dogs diagnosed with oral tumours.
- Dogs with a diagnosed oral tumour and interested in pursuing CT & Surgery
Comparison of Two Surgical Techniques For The Treatment of Brachycephalic Airway Disease in French Bulldogs
Complete Title: Prospective, Randomized Trial Comparing Two Surgical Techniques For The Treatment of Brachycephalic Obstructive Airway Syndrome (BOAS) in French Bulldogs
Currently in veterinary patients, standard of care surgery for BOAS is a soft palate resection (staphylectomy). Given that some dogs still suffer from breathing difficulties following surgery, modifications that aim to provide a greater opening of the airway have been proposed. One of these procedures is the folded flap palatoplasty. The objective of this study is to compare the clinical outcome, by means of an exercise tolerance test and CT anatomy of traditional staphylectomy versus folded flap palatoplasty for the treatment in French bulldogs.
- French bulldogs <5 years of age, with breathing difficulties as a result of BOAS and are interested in pursuing CT and surgery
Evaluating the Use of Fluorescent Dyes to Assess Blood Flow in Dogs Undergoing Intestinal Resection During Foreign Body Surgery
Complete Title: Use of Fluorescent Dyes for Perfusion Assessment and Surgical Planning for Foreign Body Surgery in Dogs
In human medicine, the use of fluorescent dyes like Indocyanine Green (ICG), have been found to decrease complications in bowel surgery. ICG has not yet been used for intestinal blood flow assessment in pets but might be helpful to reduce complications associated with poor blood flow including poor healing and leakage.
The objective of this study is to determine if using advanced technology and incorporating ICG in intestinal surgery in dogs can help surgeons assess intestine blood flow to potentially improve their surgical outcomes in the future.
- Dogs undergoing intestinal surgery for foreign body removal that require part of their intestines
Comparison of Instrument Size when Conducting Routine Laparoscopic Liver Biopsy Procedures in Small Dogs
Complete Title: Can Mini-Laparoscopy Instruments Provide Equivalent Diagnostic Samples in Routine Laparoscopic Liver Biopsy Procedures Performed in Small Dogs?
The purpose of this study is to determine if using smaller instruments for liver biopsies in small dogs can provide equivalent diagnostic answers to that obtained using standard instruments and would allow the procedure to be performed in future pets using smaller incisions and smaller instruments.
- Any dog 10kg or less scheduled for minimally invasive liver biopsy at the OVC
