RESUMO

Endoscopy is widely used to remove gastric foreign bodies using grasping forceps and loop snares to manipulate and retrieve the foreign material. However, as not all foreign bodies can be removed using conventional endoscopic techniques, this case series describes the use of bottle liners for the removal of gastric foreign bodies in 12 dogs between 2020 and 2023. A 4 oz bottle liner (Drop-Ins) was placed at the end of the endoscope and pushed into the stomach. With the help of forceps introduced into the operating channel, the foreign body was pushed into the bottle liner. The bottle liner containing the foreign body was then extracted with the help of traction threads. The technique was used as the initial retrieval method in 5 dogs because of smooth (i.e., difficult to grasp) or sharp (i.e., that may damage the digestive tract mucosa during removal) foreign bodies and as a rescue procedure in 7 dogs. Foreign body retrieval was successful in all 12 dogs, with minor complications reported in 5 dogs (erosions and bleeding of the gastroesophageal sphincter). The use of a bottle liner represents an affordable alternative to gastrotomy when foreign bodies cannot be grasped with forceps or snares.

RESUMO

OBJECTIVE: To evaluate the feasibility of gastroduodenoscopy in dogs premedicated with acepromazine in combination with butorphanol or methadone. STUDY DESIGN: Prospective, randomized, double-blinded clinical trial. ANIMALS: A group of 40 client-owned dogs. METHODS: Dogs were randomly allocated to one of two groups and give intramuscular acepromazine 0.02 mg kg-1 combined with either butorphanol 0.3 mg kg-1 (group ACEBUT) or methadone 0.2 mg kg-1 (group ACEMET). General anaesthesia was induced with propofol and ketamine and maintained with sevoflurane (2.3%) in oxygen. Cardiopulmonary variables were recorded at 5 minute intervals during anaesthesia. Feasibility of the entire gastroduodenoscopy was evaluated with a visual analogue scale (VAS) from 0 (best) to 100 (worst) (primary outcome of the study). Lower oesophageal sphincter dilatation and duodenal intubation were scored. Pylorus diameter was measured with standard endoscopic inflatable balloons. Overall cardiovascular stability was assessed during anaesthesia, using a VAS (0-100), as was the presence of fluid in the oesophagus, regurgitation, need for mechanical ventilation, and intraoperative and postoperative rescue analgesia (secondary outcomes of the study). Differences between treatments were analysed with Mann-Whitney U, Student t test, Fisher exact test or mixed model analysis of variance as appropriate. Subsequently, feasibility VAS of the gastroduodenoscopy was assessed for noninferiority between groups. The noninferiority margin was set as -10. RESULTS: All gastroduodenoscopies were successfully completed in both groups using an endoscope tip diameter of 12.8 mm in all but one dog. Feasibility of gastroduodenoscopy was evaluated as 2.9 ± 5.6 in group ACEBUT and 5.1 ± 5.8 in group ACEMET. No significant differences between groups were detected in any measured or assessed variables, and noninferiority was confirmed. CONCLUSION AND CLINICAL RELEVANCE: In our study population, the effects of methadone and butorphanol when combined with acepromazine were comparable.

RESUMO

Although cytology is a rapid diagnostic procedure in dogs, the cytologic criteria of endoscopic biopsies for chronic enteritis and intestinal lymphoma are not well defined. An immediate diagnosis using cytology would benefit patients by enabling prompt initiation of therapy. The objective of this study was to investigate the correlation between the results of endoscopic cytology and histopathology. In this study, 167 dogs with clinical signs of chronic gastrointestinal disease were included. On the basis of histopathology, the following diagnoses were determined: lymphocytic-plasmacytic enteritis in 93 dogs; eosinophilic enteritis in 5 dogs; small cell intestinal lymphoma in 45 dogs; and large cell intestinal lymphoma in 24 dogs. Two clinical pathologists retrospectively evaluated the endoscopic cytology of squash-smear preparations. The cytologic diagnoses of inflammation, small cell lymphoma, and large cell lymphoma were based on the severity of lymphocyte infiltration, the size of infiltrated lymphocytes, and eosinophil/mast cell infiltration. The clinical severity score was significantly increased along with the degree of lymphocyte infiltration evaluated by cytology. The cytologic diagnosis was in complete agreement with the histopathologic diagnosis in 136 of 167 (81.4%) cases. For the differentiation between enteritis and lymphoma, endoscopic cytology had a sensitivity of 98.6%, a specificity of 73.5%, a positive predictive value of 72.3%, and a negative predictive value of 98.6%. The log-rank test and Cox regression analysis showed that the results of cytology predicted the prognosis. These results suggest that endoscopic cytology is a useful technique to aid diagnosis of intestinal inflammation and lymphoma in dogs.

RESUMO

Two African grey parrots ( Psittacus erithacus) and one hyacinth macaw ( Anodorhynchus hyacinthinus) were examined because of varying clinical signs ranging from general lethargy to seizure-like episodes and regurgitation. Radiography and fluoroscopy in the 3 birds demonstrated variable degrees of gastric abnormalities, suggesting the presence of foreign material or stricture-like defects. Upper gastrointestinal rigid endoscopy by ingluviotomy revealed foreign bodies that were removed endoscopically. Minor postoperative complications were pulmonary congestion or mild aspiration and cardiac arrhythmia, both of which resolved, and no serious deleterious effects were associated with endoscopy in the short or long term. Endoscopy is recommended for examination and removal of foreign bodies from the upper gastrointestinal tract because it is less invasive and traumatic than traditional surgical approaches.

RESUMO

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). Tasks were scored based on completion time, and specific rating scales were developed to assess performance. Internal consistency and inter-rater agreement were assessed. Face and content validity were determined using a 5-point Likert-type scale questionnaire. The novices needed considerably more time than the experts to perform EGD, GB, and FBR, and their performance scores were significantly lower (p<.010). Inter-rater agreement and the internal validity of the rating scales were good. Face validity was excellent, and both groups agreed that the endoscopy scenarios were very realistic. The experts highly valued the usefulness of Simuldog for veterinary training and as a tool for assessing endoscopic skills. Simuldog is the first validated model specifically developed to be used as a training tool for endoscopy techniques in small animals.

RESUMO

OBJECTIVE: To compare a towel under, a warm water pad under or a forced warm air blanket over dogs as techniques to reduce heat loss during a standardized anesthetic. STUDY DESIGN: Prospective, randomized, crossover study. ANIMALS: Eight, healthy, mixed breed dogs weighing 16.3-19.6 kg. METHODS: Dogs were anesthetized four times for 90 minutes. Dogs were placed on a steel table (treatment TA), with a cotton towel (treatment TO) or a circulating warm water pad (treatment WP) between the dog and the table, or with, a towel under the dog and covered with a forced warm air blanket (treatment WAB). Rectal temperature (RT) was recorded at 5 minute intervals. Changes in temperature (ΔRT) were calculated as the RT at a given point subtracted from the RT before anesthesia (baseline) and compared over time. RESULTS: After 90 minutes of anesthesia, the ΔRT was 3.42 °C ± 0.29 for TA, 2.78 °C ± 0.43 for TO, 1.98 °C ± 0.29 for WP, and 0.91 °C ± 0.27 for WAB. Significant differences in ΔRT occurred between TA and WAB at 20 minutes (0.94 °C ± 0.42, p = 0.0206), between TO and WAB at 30 minutes (1.16 °C ± 0.62, p = 0.0063), between WP and WAB at 50 minutes (0.96 °C ± 0.98, p = 0.0249), between TA and WP at 35 minutes (1.19 °C ± 0.54, p = 0.0091), between TO and WP at 70 minutes (1.12 °C ± 0.56, p = 0.0248), and between TA and TO at 75 minutes (0.96 °C ± 0.62, p = 0.0313). These differences in ΔRT between each treatment persisted from the times indicated until the end of the anesthesia. CONCLUSION AND CLINICAL RELEVANCE: During anesthesia, forced warm air blankets were superior to other methods tested for limiting heat loss. An efficient heat loss technique should be used for anesthesia longer than 20 minutes duration in medium sized dogs.

RESUMO

BACKGROUND: Interventional radiology (IR) and interventional endoscopy (IE) have broad potential for minimally invasive therapy in veterinary patients, but the scope of original peer-reviewed veterinary IR/IE research publications has not been described. OBJECTIVES: Catalogue published applications and indications for noncardiac therapeutic IR/IE in animals and describe type and quality of veterinary IR/IE research over 20 years. METHODS: Highly-cited veterinary journals were searched to identify articles published 2000 to 2019 involving therapeutic IR/IE applications for clinical veterinary patients. Articles were assigned a level of evidence (LOE) according to published standards. Authorship, animal data, study design, and interventions were described. Change in publication rate, study size, and LOE of IR/IE articles over time was analyzed. RESULTS: One hundred fifty-nine of 15 512 (1%) articles were eligible, including 2972 animals. All studies were low LOE and 43% were case reports with ≤5 animals. Number of IR/IE articles per year (P < .001), proportion of journals' articles pertaining to IR/IE (P = .02), and study size (P = .04) all increased over time, but LOE (P = .07) did not. Common target body systems were urinary (40%), digestive (23%) respiratory (20%), and vascular (13%). Common indications were nonvascular luminal obstructions (47%), object retrieval (14%), and congenital anomalies (13%). Most procedures involved indwelling medical devices or embolic agents, whereas tissue resection and other procedures were less common. Procedures utilized fluoroscopy (43%), endoscopy (33%), ultrasound (8%), digital radiography (1%), or fluoroscopy in combination with other modalities (16%). CONCLUSIONS: Treatments involving IR/IE have wide applicability in veterinary medicine but large, rigorous, and comparative studies describing these procedures are lacking.

RESUMO

BACKGROUND: Angiodysplasia (AGD) is rarely diagnosed in dogs with gastrointestinal bleeding (GIB) and is reported in case reports in dogs. OBJECTIVE: Describe signalment, clinical and diagnostic features of dogs with gastrointestinal (GI) AGD diagnosed by video capsule endoscopy (VCE). ANIMALS: Dogs with overt or suspected GIB which underwent VCE. METHODS: Dogs for which a VCE was submitted for overt or suspected GIB from 2016 to 2021 were selected retrospectively. Medical records and full-length VCE recordings where AGDs were initially detected, were reviewed by 2 trained internists. AGD was considered definitive if 2 readers detected it. Signalment, clinical signs, blood work, medications, concurrent diseases, findings of previous conventional endoscopy, and surgical exploration (if applicable) of dogs with AGD were recorded. RESULTS: Definitive AGD was diagnosed in 15 of 291 (5%) dogs (12 males, 3 females). Twelve (80%) had overt GIB, 11 (73%) had hematochezia, and 6 (40%) had microcytic and hypochromic anemia. AGD was missed by conventional endoscopy in 9/9 dogs and exploratory surgery in 3/3 dogs. Thirteen capsules were administered by mouth (1 incomplete study), and 2 via endoscopy directly into the duodenum. AGD was visualized in the stomach of 3 dogs, in the small intestine of 4, and in the colon of 13 dogs. CONCLUSION AND CLINICAL IMPORTANCE: Although rare, AGD should be considered in dogs with suspected GIB after a negative conventional endoscopy or surgical exporation. Video capsuel endoscopy appears to be a sensitive test to identify AGD within the GI tract.

RESUMO

OBJECTIVE: To describe the conservative management and outcome of gastrointestinal metallic sharp-pointed straight foreign bodies in dogs and cats. MATERIALS AND METHODS: Clinical records of dogs and cats presented to a university teaching hospital between 2003 and 2021 with gastrointestinal metallic sharp-pointed straight foreign bodies (e.g. needles, pins, nails) were reviewed. Conservative management was defined as leaving the foreign body in situ. Cases were excluded if the foreign body was identified outside of the gastrointestinal tract (including oropharynx and oesophagus) or if it was removed by endoscopy or surgery as the first treatment choice. Patient signalment, presenting complaint, foreign body location, treatment, complications, gastrointestinal transit time, length of hospitalisation and outcome were recorded. RESULTS: A total of 17 cases (13 dogs and four cats) were included in the study, being treated with primary conservative therapeutic approach (11) or following failure of endoscopy (two), surgery (three) or both (one). Clinical signs associated with the foreign body were reported in three (17.6%) cases. Conservative management was successful in 15 (88.2%) cases, with no complications reported. Patients were clinically and radiographically monitored with variable supportive care. In two (11.8%) cases, surgery was subsequently performed as the foreign body failed to progress on repeated radiographs after 24 hours. Mean foreign body gastrointestinal transit time for patients treated conservatively was 59.2 (±31.4) hours. All patients survived to discharge. CLINICAL SIGNIFICANCE: Conservative management is a treatment option for clinically stable cats and dogs with metallic sharp-pointed straight gastrointestinal foreign bodies in the absence of perforation.

RESUMO

A green moray eel (Gymnothorax funebris) was evaluated for chronic regurgitation. By using flexible endoscopy, the gastrointestinal tract was evaluated and revealed multifocal proliferative gastric masses and an intestinal ulcer. Biopsy specimens revealed gastric mucus gland hyperplasia, intestinal nematodiasis, and mild enteritis. Esophagoscopy and gastroscopy were performed by using a larger endoscope (length, 200 cm). A smaller endoscope (length, 100 cm) facilitated entering the intestinal tract in normograde or retrograde directions. A control eel was also evaluated, and no gross or histologic abnormalities were detected. The case eel was treated with metoclopramide and fenbendazole, responded well to therapy, and regurgitation decreased. A year later, the animal died of unrelated causes. Necropsy revealed coelomic gastric adhesions. The gastric proliferative lesions were associated with degeneration and necrosis of gastric pit mucosa without significant inflammation; etiology was unknown. Gastrointestinal endoscopy proved a useful diagnostic tool for evaluation and biopsy collection in this eel species.

RESUMO

Twenty apparently healthy buffaloes were withdrawn of feed and water for 48 hours. Buffaloes were administered with fluids and were subjected to endoscopy every 12 hours. Olympus™ [GIF V70] flexible video endoscope was passed through the ventral nasal meatus, the pharynx, oesophagus and then into the reticulo-rumen in physically restrained buffaloes. The entire reticulum and part of the rumen could be visualized, when the animals were off feed and water for at least 48 hours and evacuations of rumen contents were done even after 48 hours of starvation to visualize the rumen in six buffaloes. The reticulum appeared light brown to pink coloured with honeycomb shape and the rumen appeared smooth, shiny pink, with numerous papillae throughout its surface. The procedure was well tolerated by all the buffaloes and satisfactory reticular and ruminal images could be obtained including biopsy.

RESUMO

Ureteral endoscopy is a routine procedure in human medicine, whereas the reports of this procedure on horses are few and far between. The aim of this paper is to describe the endoscopic technique to evaluate the ureters in standing, sedated horses. An endoscopy of the ureters and lower urinary tract was performed using flexible endoscopes on 4 horses, 3 mares and one gelding. The animals were sedated with alpha-2-agonists and an epidural anaesthesia was given. An endoscopy of the ureter in the horse is easy to perform, causes the animal no adverse effects and could provide significant information on the diagnosis and prognosis of diseases of the urinary tract.

RESUMO

BACKGROUND: Esophageal varices (EV) are abnormally dilated veins in the esophagus caused by alterations of blood flow or pressure. Esophageal variceal hemorrhage is a major complication of hepatic disease in humans, but a lack of information exists regarding associated adverse events in dogs. OBJECTIVE: To describe the clinical manifestations and associated etiologies and outcomes of dogs with EV. ANIMALS: Twenty-five client-owned dogs with EV diagnosed via computed tomography (CT), endoscopy, or fluoroscopy. METHODS: Retrospective case series. Cases were identified by review of the hospital imaging records database between 2010 and 2020. Signalment, clinical signs, and outcomes were documented. When present, additional collateral vasculature was also recorded. Cases were subcategorized into suspected etiology based upon the anatomic location or absence of an attributable underlying disease process, as well as the direction of blood flow. RESULTS: Twenty-four of 25 cases were identified via CT, with a prevalence of 0.012% (24/1950 total studies). Presenting clinical signs were nonspecific, and more likely because of the underlying cause as opposed to complications secondary to EV themselves. Etiologic anatomic locations were similar in occurrence between the abdomen (N = 14) and thorax (N = 11). All cases with an abdominal etiologic location had presumed or confirmed portal hypertension and 9/11 cases with a thoracic etiologic location had pulmonary, caval, or systemic hypertension. No cases died or were euthanized as a direct result of EV or associated hemorrhage. CONCLUSIONS AND CLINICAL IMPORTANCE: Esophageal varices are rarely reported in dogs and commonly identified concurrently with portal, pulmonary, and caval hypertension. Hemorrhage is not a common clinical manifestation of EV.

RESUMO

Interest in noninvasive feeding tube placement in companion animals led to the adaption of a human technique utilizing endoscopy to place nasojejunal feeding tubes. Data from medical records in which nasojejunal feeding tubes were attempted were reviewed. Feeding tubes were attempted and successfully placed in five dogs within a median of 35 min. Feeding tubes remained in place for approximately 7 days. Complications included facial irritation (5/5), sneezing (5/5), fractured facial sutures (4/5), vomiting (3/5), diarrhea (3/5), crimping of feeding tube (3/5), regurgitation (1/5), epistaxis (1/5), clogging of the feeding tube (2/5), and oral migration with premature removal of the feeding tube (1/5). The deployment technique used in this study was found to be cumbersome. Despite minor complications, endoscopy can be used to rapidly and accurately place nasoenteric feeding devices.

RESUMO

BACKGROUND: Prospective studies describing video capsule endoscopy (VCE), its feasibility, and complications in dogs are limited. OBJECTIVE: To assess VCE, quality of visualization, complications, and risk factors for incomplete studies in dogs with overt or questionable gastrointestinal bleeding (GIB). ANIMALS: Forty dogs with overt or questionable GIB. METHODS: Prospective, multicenter, interventional study. From August 2017 to March 2020, dogs were examined by VCE (ALICAM) because of overt or questionable GIB. Reported outcomes included diagnostic results of VCE study, quality of visualization, and complications. Risk factors for incomplete studies were evaluated using logistic regression. RESULTS: In total, 40 dogs (13 overt, 27 questionable GIB) were included. The capsules were administered PO in 29 and endoscopically in 11 dogs (6 duodenum, 5 stomach). One capsule was not retrieved. In 24 of 39 recordings, bleeding lesions were identified (10 overt GIB, 14 questionable GIB). Overall, the quality of visualization was poor to limited in the stomach and colon, and adequate to good in the small intestine. The most common complication was an incomplete study in 15/39 studies, particularly after oral administration (13/28). Risk factors for incomplete study after oral administration included administration of simethicone or opioids, chronic enteropathy, and capsule gastric transit time >6 hours. CONCLUSIONS AND CLINICAL IMPORTANCE: Video capsule endoscopy can be used to diagnose a variety of lesions causing bleeding in the gastrointestinal tract of dogs with questionable GIB. Incomplete studies are the most common complications in dogs after oral administration of capsules.

There has been an increase in the number of Jack Russell Terriers (JRTs) diagnosed with adenomas and adenocarcinomas of the gastrointestinal tract in Japan. This study retrospectively investigated the clinical and histopathological features and prognosis of adenocarcinomas arising in the gastrointestinal tract in JRT dogs. Seven JRTs and 39 dogs of other breeds diagnosed with gastrointestinal adenocarcinoma were included in the study. The most common sites of gastrointestinal adenocarcinoma in JRTs were the pylorus and rectum. On histopathological examination, these adenocarcinomas showed a papillary or tubular growth pattern, and the lesions were confined within the mucosal epithelium and poorly invasive. Among all dogs with gastric adenocarcinoma, the median survival time (MST) for five of the JRTs could not be determined because more than half of the cases remained alive, while the MST for nine non-JRT dogs was 34 days. Among all dogs with adenocarcinoma in the large intestine, the MST for three of the JRTs could not be determined, while the MST for nine non-JRT dogs was 1,973 days. The difference in MST between JRT and non-JRT dogs with gastric adenocarcinoma was significant (P=0.0220). Since gastrointestinal adenocarcinomas in JRTs show distinct characteristics with respect to their clinical features, treatment course, and prognosis, a different surgical and medical treatment plan should be considered compared to the management of gastrointestinal adenocarcinomas in other dog breeds.

RESUMO

OBJECTIVE: To determine short- and long-term complications in clinically normal dogs after endoscopically assisted gastropexy. DESIGN: Prospective case series. ANIMALS: 24 dogs. PROCEDURES: Endoscopically assisted gastropexy was performed on each dog. Dogs were evaluated laparoscopically at 1 or 6 months after surgery to assess integrity of the gastropexy. Long-term outcome was determined via telephone conversations conducted with owners > or = 1 year after surgery. RESULTS: Mean +/- SD gastropexy length was 4.5 +/- 0.9 cm, and mean duration of surgery was 22 +/- 5 minutes. One dog had a partially rotated stomach at the time of insufflation, which was corrected by untwisting the stomach with Babcock forceps. Two dogs vomited within 4 weeks after surgery, but the vomiting resolved in both dogs. Four dogs had diarrhea within 4 weeks after surgery, which resolved without medical intervention. In all dogs, the gastropexy site was firmly adhered to the abdominal wall at the level of the pyloric antrum. Long-term follow-up information was available for 23 dogs, none of which had any episodes of gastric dilatation-volvulus a mean of 1.4 years after gastropexy. CONCLUSIONS AND CLINICAL RELEVANCE: Endoscopically assisted gastropexy can be a simple, fast, safe, and reliable method for performing prophylactic gastropexy in dogs. At 1 and 6 months after gastropexy, adequate placement and adhesion of the gastropexy site to the body wall was confirmed. Such a procedure could maximize the benefits of minimally invasive surgery, such as decreases in morbidity rate and anesthetic time. This technique appeared to be suitable as an alternative to laparoscopic-assisted gastropexy.
