Special Issue Information

Dear Colleagues,

Oesophagitis is an inflammatory process of the oesophageal mucosa which may increase morbidity and lead to severe oesophageal stricture, with detrimental consequences. In dogs and cats, the main cause of oesophagitis is gastro-oesophageal reflux (GOR), which most commonly occurs peri-operatively, and it passes unnoticed (“silent” reflux), showing its aftermath days or weeks later. Several factors have been identified to predispose dogs and cats to GOR, including age, type of surgical procedure, drugs used for pre-medication and/or anaesthesia, volume and acidity of gastric content, and the duration of preoperative fasting. For many years, strict preoperative fasting rules to ensure an empty stomach at induction have been a common practice. However, there is evidence that long periods of pre-anaesthetic fasting may have negative results, such as increased gastric content acidity and risk for GOR.

Another cause of oesophagitis in dogs and cats seems to be the reflux occurring in awake animals, with no apparent causing factors, and  is attributed to insufficiency of the lower oesophageal sphincter. This condition is analogous to the gatro-oesophageal reflux disease in humans, which is widespread and may lead to oesophageal malignancy. In dogs and cats, this “disease” is hardly diagnosed and poorly understood, but it is suspected to cause pain and suffering.

The aim of this Special Issue is to present up-do-date research on GOR in dogs and cats, focusing on the understanding of this condition, clinical implications, and possible prevention strategies.
