Complications associated with esophagostomy tube placement in chelonian patients

Esophagostomy tube placement is commonly performed in chelonian patients, either to provide nutritional support during a period of anorexia or for administration of oral medications. Placement is usually a quick and simple procedure performed under a short general anaesthetic or sedation. Studies in mammals indicate that tubes are associated with relatively few major complications and appear well tolerated by patients. The aim of this study was to describe and quantify the complications associated with esophagostomy tube placement in chelonians. Medical records for patients presenting between 2013 and 2018 were reviewed retrospectively at three veterinary practices. All chelonian patients that had an esophagostomy tube placed during this time period were included in the study. Reasons for tube placement, frequency and types of complications were recorded. Complications were noted in 40/98 (40.82%) patients, with tube obstruction and tube displacement by the patient being the two most commonly seen problems. Complications associated with esophagostomy tube placement occur commonly in chelonian patients, but in the majority of cases are minor issues which are easily managed. Major complications are rare but can potentially have fatal consequences.
