Gastrojejunostomy as a treatment for gastric outflow disorders in four adult horses.

Abstract: Four adult horses with histories of moderate abdominal pain and inappetence were diagnosed with delayed gastric emptying and gastric impaction attributed to pyloroduodenal obstruction (three cases) or duodenitis (one case). A stapled side-to-side gastrojejunostomy was performed on all horses. Two horses returned to work and survived ≥3 years. One horse was euthanased 6 months post-surgery due to recurrent abdominal pain, and one was found dead 5 months postsurgery after an unattended foaling.

The research investigates the effectiveness of gastrojejunostomy, a surgical procedure, in treating gastric outflow disorders in four adult horses which manifested as abdominal pain and loss of appetite. The results of the study showed that half of the horses returned to work and lived for at least three more years, whereas the other half died due to complications unaffiliated with the surgical procedure within six months post-surgery.

Study Background

  • The study focused on four adult horses that presented symptoms of moderate abdominal pain and inappetence, suggesting an issue with their gastric health.
  • The medical diagnoses identified delayed gastric emptying, suggesting that the horses had difficulty passing food from the stomach, and gastric impaction, which involves an obstruction in the stomach compromising its functionality.
  • These issues were attributed to pyloroduodenal obstruction in three cases, which is a hindrance in the passage connecting the stomach to the small intestine, or duodenitis in one case, characterized by inflammation in the first section of the small intestine.

Procedure and Results

  • All four horses underwent a surgical procedure known as a stapled side-to-side gastrojejunostomy. This involved the creation of an anastomosis or connection between the stomach and the jejunum, bypassing the obstructed or inflamed area, to facilitate the normal flow of food matter.
  • The post-operative results were positive for half of the horses. Two of them showed improvement, were able to return to work, and lived for at least three more years post-surgery.

Limitations and Concluding Events

  • The remaining two horses did not fare well post-surgery. One horse had to be euthanased 6 months post-surgery due to recurrent abdominal pain suggesting the persistence or recurrence of the original gastric outflow problem.
  • The fourth horse died 5 months post-surgery, but the death was associated with complications from an unattended birth, not directly linked to the surgical procedure or the initial gastric problem.
  • Overall, these findings suggest that while gastrojejunostomy can effectively treat gastric outflow disorders in some cases, it is not a universally effective solution, and the survival rates post-surgery could be significantly influenced by other health factors and complications.
