History

A 10-month-old sexually intact male Shetland Sheepdog was evaluated by its primary veterinarian for a 1-day history of decreased appetite and mild lethargy. On physical examination, the dog was noted to have increased respiratory rate and effort with decreased lung sounds on the left side. The dog was not receiving heartworm preventative. The veterinarian performed survey radiography, made a diagnosis of pneumothorax, and performed bilateral thoracocentesis. The dog was referred to a surgical center for advanced imaging and continued care.

On evaluation at the referral center the following day, the owner stated that the dog seemed clinically improved, with

Abstract

OBJECTIVE

To determine long-term outcomes and factors associated with those outcomes in dogs with gastroesophageal intussusception (GEI).

ANIMALS

36 dogs with GEI evaluated at 16 veterinary hospitals from January 2000 through January 2018.

PROCEDURES

Medical records of included dogs were reviewed to collect information regarding signalment, clinical signs, physical examination findings, blood work and diagnostic imaging results, surgical findings, and outcome. Factors were evaluated for associations with various outcomes.

RESULTS

Median age of dogs with GEI was 13.2 months, and males (72% [26/36]) and German Shepherd Dogs (33% [12/36]) were most common. Vomiting (67% [24/36]) and regurgitation (33% [12/36]) were the most common clinical signs. Ten of 36 (28%) dogs were euthanized without treatment, and 26 (72%) underwent treatment (25 surgically and 1 endoscopically). Twenty-three of the 26 (88%) treated dogs survived to discharge; median survival time was 995 days. At last follow-up, 15 of the 23 (65%) surviving dogs remained alive and 8 (35%) had died for reasons related to persistent regurgitation (n = 6) or reasons unrelated to GEI (2). Of the 10 dogs for which owners were contacted, 7 had persistent regurgitation, the severity of which was reduced through managed feedings. Dogs with acute (≤ 7 days) clinical signs or a previous diagnosis of megaesophagus were more likely to have persistent regurgitation than were dogs without these factors.

CONCLUSIONS AND CLINICAL RELEVANCE

Treatment should be considered for dogs with GEI given the high rate of survival to discharge and median survival time. Although persistent regurgitation was common after treatment, a satisfactory outcome was possible with medical management, including managed feedings and medications.
