Identification, management and outcome of postoperative hemoperitoneum in 23 horses after emergency exploratory celiotomy for gastrointestinal disease.

The research article discusses a study on postoperative hemoperitoneum (bleeding into the abdominal cavity) in horses that underwent an emergency surgical procedure (exploratory celiotomy) due to gastrointestinal problems. The study identifies factors associated with this condition, its management techniques, and the survival rate of the affected horses.

Study Methodology

• The study is a retrospective case series that reviewed medical records from 1985 to 2012.
• It included 23 horses that developed postoperative hemoperitoneum after emergency exploratory celiotomy due to gastrointestinal disease.
• Any cases of pre-existing hemoperitoneum during surgery and non-surgical hemoperitoneum were excluded from the study.

Research Findings

• Among 4520 horses that had undergone the same emergency procedure, 0.5% met the study’s inclusion criteria.
• Thoroughbreds were significantly overrepresented, indicating a potential breed predisposition to the condition.
• Hemoperitoneum was significantly associated with intestinal resection, an operation in which a portion of the intestine is removed.
• The condition was recognized an average of 1.0 ± 0.7 days after surgery and linked with tachycardia (an abnormally fast heart rate), decreasing hematocrit (a decrease in the proportion of red blood cells), incisional drainage, or the ultrasonographic identification of swirling, echoic abdominal fluid.

Management and Outcome

• Various treatments were employed, including intravenous fluid therapy, colloid support, blood transfusions, and antifibrinolytic agents (medications to prevent excessive bleeding).
• 65% of the horses (15 out of 23) survived and were discharged, with survival associated with admission lactate (a measure of tissue oxygenation) and length of hospital stay.

Conclusions

• The research concludes that postoperative hemoperitoneum is a rare but notable complication of exploratory celiotomy in horses. It should be considered when there are signs of abdominal discomfort and a decline in hematocrit in the early postoperative period.
• The prognosis for horses with this condition is guarded, due to potential complications such as septic peritonitis (an infection of the lining of the abdominal cavity) and adhesion formation (bands of scar tissue that form between abdominal tissues and organs).
