Surgical treatment for acute small intestinal obstruction caused by Parascaris equorum infection in 15 horses (2002-2011).

The research is on surgical treatments for horses with intestinal obstruction due to Parascaris equorum infection, aiming to gauge whether a method of manually evacuating the blockage and avoiding opening the small intestine improves post-surgery survival rates.

Research Focus and Objective

• The study revolves around a surgical procedure as a treatment option for horses affected by Parascaris equorum, a kind of roundworm. The infection caused by this parasite often leads to intestinal obstruction, a condition that typically carries a pessimistic prognosis, with surgery frequently delayed or even animals euthanized following diagnosis.
• The researchers aimed to present a divergent clinical view that such obstruction could have a better prognosis than generally perceived.
• The primary objective was to scrutinize whether the manual evacuation of the obstruction, combined with refraining from opening the small intestine, could ultimately enhance the survival prognosis for horses afflicted with this parasite-induced infection.

Methodology

• For this study, the research team meticulously glossed over the medical records of all horses that had undergone exploratory celiotomy for ascarid impaction at their hospital from 2002 to 2011.
• They paid close attention to surgical findings, surgical techniques, any ensuing complications, and both short-term and long-term survival rates.
• To evaluate the relationship between categorical variables, the Fisher’s exact test was used. Statistical significance was considered when P was less than 0.05.

Outcomes

• The study used a sample size of 15 horses. The researchers found that 80% (12 out of 15) of the horses survived up to discharge, and 60% (6 out of 10) managed a survival rate of at least one year. There are 5 horses that are doing well but are still in recovery.
• Horses that underwent small intestinal enterotomy or resection and anastomosis were less likely to survive to discharge, marking a critical finding in the study.

Conclusions

• The research concluded that manually evacuating ascarid impaction into the cecum and avoiding opening the small intestine significantly improved survival rates in horses with ascarid impaction.
• The study suggests that the key to better surgical outcomes for horses afflicted with ascarid impaction could be to refrain from opening the small intestine during surgery.
