Research paper thumbnail of Endoscopic Removal of Foreign Body in Upper Gastrointestinal Tract in Dogs: Success Rate and Complications

Acta Scientiae Veterinariae, May 28, 2020

Background: Dogs and cats with acute signs of choking, retching, cough, vomiting, regurgitation, ... more Background: Dogs and cats with acute signs of choking, retching, cough, vomiting, regurgitation, hypersalivation, dysphagia and odynophagia should have the presence of a gastrointestinal foreign body (FB) as part of their differential diagnosis, where it is a frequent condition in the care of small animals. Most objects lodged in the esophagus, stomach, and proximal duodenum can be removed by upper digestive endoscopy, a curative, little invasive procedure. The objective of our study was to evaluate the physical aspects and location of esophageal and gastric FBs observed in 88 dogs and the age and breed of the affected animals, and to determine the success rate and eventual complications associated with the procedure as well. Materials, Methods & Results: Eighty-eight cases of dogs, males and females of varying ages and breeds, submitted to upper digestive endoscopy were selected because of suspicion of esophageal or gastric FBs. The endoscopic procedure aimed at confirming the diagnosis, whether or not followed by endoscopic removal of these objects. Prior to endoscopy, the animals had laboratory tests (blood count and serum biochemistry) and subsequently to the anesthetic protocols of choice for each case. Data including breed, age, type of constituent material and anatomical location of the FB, endoscopic procedure success rate and complications were recorded and descriptively evaluated. Of the 88 dogs evaluated, 60% (n = 53) were male and 40% (n = 35) female. According to the breed of the animals, 55% (n = 49) were small-breed dogs, 29% (n = 25) large-breed dogs, and 8% (n = 7) medium-breed dogs, and 8% were of mixed breed dogs, which could assume various sizes. Shih tzus accounted for 18% (n = 16) of the animals, Lhasa apso 8% (n = 7) and mixed breed 8% (n = 7), where these were the most frequently affected breeds. Regarding age, animals 1 to 5 years old represented 66% (n = 58) of the patients, and those 6 to 10 years old accounted for 20% (n = 18), while 11% of the dogs were over 10 years old (n = 10). Two animals (3%) had no information about their ages. Pieces of cloth were the most frequently found FBs, representing 20% (n = 20), followed by animal bones (19%) and fruit pits (10%). As for location, 78% (n = 69) of the FBs were located in the stomach and 22% (n = 19) in the esophagus. The success rate of endoscopic FB removal in this study was 83% (n = 73). In 76% (n = 67) of the animals, there were no complications due to the presence of FB in the upper gastrointestinal tract. The most frequent complications were esophageal ulcerations (n = 7) and inability to move the FB (n = 5) and adherences (n = 4). Discussion: The results showed that small-breed dogs, especially Shih tzus and Yorkshires, represented a larger number of cases, probably due to their popularity in Brazil, where the study was conducted. Males were more prevalent than females, and the most affected age was between 1 and 5 years, with emphasis on younger animals. There were more gastric FB cases compared to esophageal FB cases, which was related to the interval between ingestion of the object and veterinary care. Although not the most prevalent FB, the high rate of mango pits can be explained by the vast number of mango trees in the Federal District. There were few complications compared to the success of cases, indicating that endoscopy is the procedure of choice for the diagnosis and removal of FBs from the gastrointestinal tract.

One hundred and forty five healthy horses, adults of both sexes, of the following breeds - Arabian horse (AH; n=20), Mangalarga Marchador (MM; n=50), Pure Blood Lusitano (PBL; n=35), Quarter Horse (QH; n=20), Brazilian Sport Horse (BSH; n=20)-were investigated. Corneal touch threshold (CTT) was measured with a Cochet-Bonnet esthesiometer in five different corneal regions. Measurements of the median central CTT were: 4.50±0.50cm (AH), 3.50±0.56cm (MM), 3.00±0.25cm (PBL), 2.50±0.44cm (QH) and 2.50±0.00cm (BSH). The central region was the most sensitive and the dorsal region the least sensitive corneal region for all breeds. CTT values differed for corneal regions and horse breeds. The CTT values were different among the corneal regions and the horse breeds. Arabian horses presented higher sensitivity values being the most sensitive in all of the corneal regions.

Experimental lamellar keratoplasty in rabbits using microfibrilar cellulose membrane. Clinical, morphological and immunohistochemical findings Ceratoplastia lamelar experimental em coelhos usando membrana microfibrilar de celulose. Achados clínicos, morfológicos e imunoistoquímicos ABSTRACT The clinical, histopathological and immunohistochemical features of the cornea were investigated in adult male New Zealand rabbits submitted to lamellar keratoplasty with microfibrillar cellulose membrane. Thirty animals were divided into five groups (n=6) and evaluated up to 60 days after surgery. Clinical examination revealed moderate manifestations of edema, blepharospasm and photophobia on the second day, which became mild or disappeared after the seventh day. This period was characterized clinically by repair of the corneal defect. Histopathological analysis showed the presence of a thin layer of squamous cells covering the damaged area as early as 7 th day, accompanied by a mild infiltrate of polymorphonuclear cells. Blood vessels were observed in the epithelium after the 15 th day, which had regressed by day 48. Ki67 antibody labeling showed an increase of proliferating cells in the epithelium by the 15 th day and in the stroma by day 30. Remodeling and epithelial adhesion were observed during this period. Microfibrillar cellulose membrane (Bionext ®) used for lamellar keratoplasty was found to yield good results considering the good integration of the implant.

Rebound tonometry was measured with both TonoVet® and TonoVet Plus®. All eyes were evaluated with slit‐lamp biomicroscopy. Following pharmacological mydriasis, direct fundoscopy was performed. ANOVA and Tukey tests were used for the data analysis.ResultsThere were upper and lower eyelids, as well as a third eyelid. Eyelashes were present on the upper eyelid, while meibomian glands openings were visible on both. The bulbar conjunctiva was pigmented. The pupil was obliquely horizontally ovoid and teardrop shaped when miotic. The color of the iris and tapetum lucidum varied with age. The optic disk was round, and the retina was holangiotic. The mean ± standard deviation values obtained were as follows: STT: 2.50 ± 2.39 mm/min; rebound tonometry: 9.50 ± 2.43 mmHg (TonoVet®, calibration P), 14.60 ± 2.82 mmHg (TonoVet®, calibration D), 18.93 ± 3.99 mmHg (TonoVet Plus®, calibration dog); applanation tonometry: 18.66 ± 4.16 mmHg; PFL: 10.98 ± 1.67 mm.Conclusions and Clinical RelevanceAnatomical and clinical ophthalmic data presented in this study are unprecedented for this species. The results can be used as clinical reference parameters, allowing for better care of these species. The lack of data for the Procyonidae family must be regarded as an incentive for more studies.

In this species, displacement of the eyeball may occur due to internal compression caused by the tooth root. The aim of this paper is to report two cases of enucleation and exenteration for correction of ocular proptosis secondary to acquired dental disease syndrome (ADDS). Case report: Two guinea pigs were treated with proptosis of the right eyeball, consanguineous and were affected by dental disease, with tooth root growth of the premolars and reserve crowns, with an aspect of dental intrusion, and alteration of the table occlusal of molars and premolars, promoting force and expulsion of the eyeball. As there was no tissue viability, they were submitted to surgery with enucleation and exenteration techniques and collections of secretion for culture with antibiogram in the pre-and intraoperative period and histopathology of the ocular tissues were performed. Results: The application of surgical techniques proved to be effective for the correction of the installed pathology, with effective healing and aesthetic character. The result of bacterial cultures was positive for only one of the animals, with results of Staphylococcus sp. negative coagulase and Aeromonas sp. pre-and trans-operatively, respectively, being sensitive to the antibiotic of choice. In addition to demonstrating tissue alterations compatible with panophthalmitis and squamous metaplasia, both course with a neutrophilic character. Conclusions: It is concluded that the techniques of enucleation and exenteration are effective in correcting proptosis, and ADDS is one of the main causes of this disease in this species, so clinical follow-up is essential to prevent and/or contain the worsening of the syndrome, preventing the evolve with the need to remove the eyeball.

Dorsal, sagittal, and transverse planes were studied. Two additional skulls were also dissected following latex injection into the nasolacrimal duct. The length and width of the nasolacrimal duct and lacrimal canaliculi, and the distance between the nasolacrimal duct and the root of the upper canine tooth at the point of closest proximity were measured.ResultsThe nasolacrimal duct followed a convoluted course, particularly in the middle and rostral portions. Duct stenosis (width reduction equal to or &gt;75%) and dilations (width increase equal to or &gt;50%) were also detected, particularly in the rostral portion. Nasolacrimal duct length and width ranged from 1.3 to 1.5 cm and 1.5 to 2.3 mm, respectively. Mean lacrimal canaliculus length and width corresponded to 3.1 mm and 0.4 mm, respectively. Mean distance from the nasolacrimal duct to the canine tooth was 2.4 mm. The root of this tooth interfered with the course of the nasolacrimal duct.ConclusionThis study provided anatomical information for clinical assessment of the nasolacrimal drainage system in Persian cats.
