Clinical assessment and outcome of a single-layer technique for anastomosis of the small intestine in horses.

This research investigates the outcomes of an intestinal surgery technique known as end-to-end anastomosis in horses, with the study focusing on 15 horses. The study recorded a short-term survival rate of 93.3% and a long-term survival rate of 84.6%.

Methodology

• The study involved 15 horses that underwent a surgical procedure called end-to-end anastomosis of the small intestine, using a single-layer technique. This procedure was performed through exploratory coeliotomy and resection of the small intestine.
• Data on each horse’s age, breed, sex, diagnosis, and treatment was collected from medical records. Moreover, records of any complications and outcomes were also gathered.
• Follow-up information was obtained via telephone conversations with owners and trainers to assess the after-effects and long-term survival rates.

Findings

• Postoperative complications were observed in five of the horses. The complications included postoperative ileus (POI), colic, peritonitis, and diarrhea.
• Due to the complications faced, a second exploratory coeliotomy was recommended for two of the 15 horses.
• The short-term survival rate, gauged as survival up to the point of being discharged from the hospital, was found to be 93.3%; 14 out of the 15 horses survived until discharge.
• The long-term survival rate, defined as survival for at least 12 months post-surgery, was 84.6%; out of 13 horses followed up, 11 survived beyond a year after surgery.

Conclusion

• The research provides valuable insights into the effectiveness and risks of end-to-end anastomosis surgery in horses. The relatively high survival rates suggest that, despite some postoperative complications, the single-layer technique for anastomosing the small intestine can be considered a viable option.
• However, the necessity of a second coeliotomy in some cases indicates that not all surgeries may go as planned, necessitating further intervention. This highlights the need for careful postoperative observation and prompt management of complications.
