A previous study demonstrated that a dose effect between 1.6 and 4.0 mg/kg bwt of omeprazole per os s.i.d. is present in the treatment equine gastric ulceration. In same study, healing glandular ulceration appeared inferior to squamous However, several limitations were recognised further investigation warranted.To investigate presence relationship under conditions may favour efficacy such as administration prior exercise after brief fast, potential differences response therapy.A blinded,...

Background To date, risk factors for equine glandular gastric disease (EGGD) have not been described in Thoroughbred racehorses. Objectives determine management associated with EGGD, identify clinical signs affected horses, and compare these to squamous (ESGD). Animals The study was carried out on 109 racehorses from 8 training yards (3 the United Kingdom 5 Australia). Methods Gastroscopic examination alongside a questionnaire regarding management, feeding, exercise, health. Results...

Summary Reasons for performing the study Studies on omeprazole have reported that doses as low 0.7 mg/kg bwt per os are potent suppressors of acid production. Yet, to date, no studies compared treatment efficacy different in clinical cases equine gastric ulceration. Furthermore, been performed compare healing response squamous and glandular mucosa suppression therapy.

Foreword The European College of Equine Internal Medicine (ECEIM) consensus statement recently made the distinction between disease squamous mucosa (Equine Squamous Gastric Disease; ESGD) and glandular Glandular EGGD) ( Sykes et al, 2015a ). Since its publication, a number reports have furthered understanding pathology management EGGD, such that new clinical guidelines for this condition were considered necessary. following are views subject specialist representing authors ECEIM statement,...

Summary Background Previous studies have demonstrated a poor response to healing of gastric glandular lesions with oral omeprazole and other medications. Objectives To evaluate the efficacy two novel treatments (misoprostol [M] combined omeprazole‐sucralfate [OS]) in horses for disease. Study design Prospective, clinical study. Methods Sixty‐three sports grade >1/4 disease were identified by gastroscopy. Horses received either 5 μg/kg misoprostol per os BID 1 h prior feeding or...

Abstract Background Equine glandular gastric disease (EGGD) is common in domesticated horses and can be challenging to treat. Oral omeprazole (ORLO) used widely but the clinical response frequently poor. Objectives To compare rates of EGGD healing improvement between ORLO a long‐acting injectable preparation (LAIO). Study design Retrospective study. Methods The case records gastroscopy images presenting masked for peer review over 12‐month period were reviewed, with blindly assessed by one...

The aims of this study were to assess the repeatability and reproducibility transabdominal ultrasonography intestinal wall thickness in adult Thoroughbred horses (n = 8). Ultrasonographic cineloops captured by one examiner from each horse for five consecutive days. During examination at least three obtained different tract locations. Measurements performed separate observers measured on occasions evaluate short-term repeatability. measurements duodenum (0.3 +/- 0.04 cm), jejunum (0.29 0.05...

Equine gastric ulcer syndrome (EGUS) is common in adult horses, particularly those involved performance disciplines. Currently, detection of EGUS by gastroscopy the only reliable ante mortem method for definitive diagnosis; however it unsuitable as a screening test because expensive, time consuming, and not readily available to most veterinarians. Sucrose permeability testing represents simple, economical alternative purposes, feasibility this approach horse has been previously reported. The...
