Veterinary endoscopy

Intestinal T-cell lymphoma is being more frequently diagnosed in dogs owing to the wide availability of endoscopy and clonality analysis in veterinary medicine. However, no epidemiological study on intestinal T-cell lymphoma has been previously performed, and hence, information about dog breed, age and sex distributions of intestinal T-cell lymphoma has largely remained unclear. In this study, breed predisposition to canine intestinal T-cell lymphoma was determined by calculating odds ratios and 95% confidential intervals...

OBJECTIVE To compare the usefulness of fresh-frozen canine cadavers (FFCCs) and a validated canine simulator model for training veterinary students in basic gastrointestinal endoscopic procedures. DESIGN Randomized trial. SAMPLE 48 veterinary students in their final year of training. PROCEDURES Students were randomly assigned to receive basic gastrointestinal endoscopic training on a canine simulator or FFCC. All students were trained as assigned in esophagogastroduodenoscopy, endoscopic gastric biopsy, and gastric foreign body removal for 2 h/d for 5 days...

Endoscopy is a common, minimally invasive diagnostic technique that can be used to observe internal organs, e.g. the stomach, and to obtain mucosal bioptic samples for histo pathological examination. The aim of this study was to analyse the concordance between endoscopic and histological evaluation of gastric diseases in dogs. One hundred twenty-nine medical records of dogs undergoing gastroscopy have been received and stored by the Veterinary Hospital of Perugia University (Perugia, Italy) between 2009-2012...

BACKGROUND: Limited evidence exists in the literature regarding whether a specific mount is preferable to use for processing endoscopically obtained gastrointestinal biopsy specimens. HYPOTHESIS/OBJECTIVES: To compare 3 methods of handling endoscopically obtained gastrointestinal biopsy specimens from collection to laboratory processing and to determine if any technique produced superior results. ANIMALS: Twenty-three dogs and cats presented for gastrointestinal signs...

BACKGROUND: Sample quality of gastrointestinal endoscopic biopsies is of paramount importance for accurate histological diagnosis. Many veterinary practices use reusable forceps as a result of perceived decreased cost. With reusable forceps, it remains unknown whether sample quality declines with repeated use and becomes inferior to single-use forceps and is therefore more or less cost effective than single-use forceps. HYPOTHESIS/OBJECTIVES: The study hypothesis was that reusable forceps sample quality would deteriorate after repeated use as compared to single-use forceps...

During endoscopy (tenoscopy) of the distal aspect of the equine digital flexor tendon sheath (DFTS), the digital manica flexoria can be visualized connecting the distal branches of the superficial digital flexor tendon. However, this structure has been inconsistently described and variably named in the veterinary literature. The objectives of this study were to describe the presence, configuration and variability of the digital manica flexoria in the equine distal limb. Dissection of 144 equine cadaveric limbs revealed the presence of this structure in all the feet, although different types and conformations were identified...

Minimally invasive interventional techniques are advancing fast in small animal medicine. These techniques utilize state-of-the-art diagnostic methods, including fluoroscopy, ultrasonography, endoscopy, and laparoscopy. Minimally invasive procedures are particularly attractive in the field of small animal urology because, in the past, treatment options for diseases of the urogenital tract were rather limited or associated with a high rate of complications. Most endourological interventions have a steep learning curve...

Minimally invasive treatment options using interventional radiology and interventional endoscopy for urologic disease have become more common over the past decade in veterinary medicine. Urinary tract obstructions and urinary incontinence are the most common reasons for urinary interventions. Ureteral obstructions are underdiagnosed and a common clinical problem in veterinary medicine. Ureteral obstructions should be considered an emergency, and decompression should be performed as quickly as possible. Diagnostic imaging is the mainstay in diagnosing a ureteral obstruction and has changed in the last few years, with ultrasound and radiographs being the most sensitive tools in making this diagnosis preoperatively...

At the Faculty of Veterinary Medicine, Cairo University, there is an increasing number of students but a limited availability of animal cadavers used for dissection, and student exposure to formalin is a known hazard. In order to address these challenges, a new method for tissue preservation was developed, the "Elnady Technique." This method is a modified form of plastination, where the chemicals used are not patented, are inexpensive and locally available, and the process is performed at room temperature. The produced specimens are realistic, durable, have no offensive odor, and are dry, soft and flexible...

The use of endoscopy in veterinary medicine has become the mainstay of diagnosis and treatment in the subspecialty of small animal urology over the past decade. This subspecialty is termed endourology. With the common incidence of urinary tract obstructions, stones disease, renal disease, and urothelial malignancies, combined with the recognized invasiveness and morbidity associated with traditional surgical techniques, the use of endoscopic-assisted alternatives using interventional endoscopic techniques has become appealing to both owners and clinicians...

Elective sterilization is a safe and well-established surgical procedure performed in dogs and cats worldwide. Conversely, chelonian sterilization has been mostly performed therapeutically, because of the intricate anatomy and difficult access to the reproductive organs, and consequently, reproductive problems and diseases remain common. With the advance of veterinary endoscopy, novel techniques of soft tissue prefemoral coelioscopic and endoscope-assisted sterilization have been published, and preventative chelonian sterilization is now a reality...

A 2-year-old male Maremma sheepdog presenting with chronic vomiting-regurgitation was examined at the University Veterinary Teaching Hospital, Camerino University. An oesophagogastroscopy with a single blue + green (BG) filter restricting wavelengths from 400 to 550 nm was carried out. A conventional white light endoscopy showed a dilated oesophagus with mildly diffuse erythematous mucosa (more accentuated proximal to the cardia); some portions of the gastric mucosa were covered with fluids and appeared only slightly erythematous...

REASONS FOR PERFORMING STUDY: The overall rate of sepsis following endoscopic surgery of synovial structures has not previously been documented. Clinical observation has led to the conjecture that tendon sheaths, in particular the carpal flexor tendon sheath, are more prone to post operative synovial sepsis than other synovial structures. OBJECTIVES: To document and investigate the rate of post operative synovial sepsis following elective endoscopic surgery. STUDY DESIGN: Retrospective case series...

The use of novel image-guided techniques in veterinary medicine has become more widespread, especially in urologic diseases. With the common incidence of urinary tract obstructions, stones disease, renal disease, and urothelial malignancies, combined with the recognized invasiveness and morbidity associated with traditional surgical techniques, the use of minimally invasive alternatives using interventional radiology and interventional endoscopy techniques has become incredibly appealing to owners and clinicians...

This article reports on the face, content, and construct validity of a new realistic composite simulator (Simuldog) used to provide training in canine gastrointestinal flexible endoscopy. The basic endoscopic procedures performed on the simulator were esophagogastroduodenoscopy (EGD), gastric biopsy (GB), and gastric foreign body removal (FBR). Construct validity was assessed by comparing the performance of novices (final-year veterinary students and recent graduates without endoscopic experience, n=30) versus experienced subjects (doctors in veterinary medicine who had performed more than 50 clinical upper gastrointestinal endoscopic procedures as a surgeon, n=15)...

OBJECTIVE: To determine the incidence of canine post-anesthetic aspiration pneumonia (AP) and to identify anesthetic agents, procedures and management factors associated with the development of AP. STUDY DESIGN: Multicenter, randomized, case-controlled retrospective study. ANIMALS: Two hundred and forty dogs affected with AP and 488 unaffected control dogs. METHODS: Electronic medical record databases at six Veterinary colleges were searched for dogs, coded for anesthesia or sedation and pneumonia from January 1999 to December 2009...

PRACTICAL RELEVANCE: Interventional radiology and interventional endoscopy (IR/IE) uses contemporary imaging modalities, such as fluoroscopy and endoscopy, to perform diagnostic and therapeutic procedures in various body parts. The majority of IR/IE procedures currently undertaken in veterinary medicine pertain to the urinary tract, and this subspecialty has been termed 'endourology'. This technology treats diseases of the renal pelvis, ureter(s), bladder and urethra. In human medicine, endourology has overtaken traditional open urologic surgery in the past 20-30 years, and in veterinary medicine similar progress is occurring...

CLINICAL CHALLENGES: Endoscopy of the feline upper respiratory tract has always taken a bit of a back seat to exploration of the canine nose and paranasal sinuses, pharynx and trachea, due to some anatomic limitations and lack of availability of appropriate-sized equipment. PRACTICAL RELEVANCE: With proper training, however, even the inexperienced endoscopist can find that endoscopy and endoscopic surgery can be of tremendous utility in feline practice. What had previously been largely off-limits sites, in terms of direct visualization and surgical intervention, the feline rhinarium, paranasal sinuses, pharynx and trachea are now anatomic areas that can be effectively visualized in most clinical scenarios...
