Evaluation of exploratory laparotomy in young horses: 102 cases (1987-1992).

The article discusses a study conducted to understand if there are differences among young horses of varying ages in terms of recovery from anesthesia, survival rates, and formation of postoperative adhesions following exploratory laparotomy. The findings indicate surgical treatment of colic in young horses resulted in survival rates similar to mature horses, with intestinal adhesion formation appearing more prevalent in younger horses, which could be due to their age or advancements in surgery and postoperative care.

Methodology

• The study was retrospective in nature and involved 102 horses that were younger than 25 months and had undergone exploratory laparotomy.
• Data on pre-, intra-, and postoperative conditions were collected through medical records, discussions with referring veterinarians, owners or trainers, and racing records.
• The research team compared survival rates (recovery from anesthesia and short- and long-term survival) with factors such as age, type of lesion, lesion location, surgical procedure used, and the development of clinically important postoperative intestinal adhesions.

Results

• Out of the 73 horses that recovered from anesthesia, 69 were available for follow-up. Among these 69 horses, 7 (10%) died due to complications related to intestinal adhesions.
• Factors like the age of the horse, type and location of the lesion, and the surgical procedure performed did not have an impact on the incidence of adhesion formation.
• The long-term survival rate post-surgery for a small-intestinal lesion stood at 34% while for a large-intestinal lesion, it was 65%.

Conclusions

• Surgical treatment of colic in young horses resulted in survival rates that are analogous to those found in mature horses.
• The incidence of clinically significant postoperative adhesions was higher compared to previous studies involving young horses. This increase could be due to the lower age of the sample group.
• Alternatively, advancements in surgical techniques and postoperative management could be enabling a larger percentage of horses to survive long-term and thus develop complications such as adhesion formation.
