Large colon impaction in horses: 147 cases (1985-1991).
Abstract: Medical records from all horses with large colon impaction admitted between 1985 and 1991 were examined. Large colon impaction was diagnosed in 147 of 1,100 (13.4%) horses with colic. One hundred thirty horses were admitted for further evaluation of acute onset of abdominal pain after having been examined and treated by referring veterinarians, and 17 horses that were hospitalized for unrelated medical problems developed large colon impaction. Female horses (92/147; 62.6%) were more commonly affected than males. The age ranged from 1 to 29 years (median, 7.1 years). Mean duration of clinical signs of abdominal pain prior to referral was 32 hours. At admittance, signs of abdominal pain were not detectable in 70/147 (48%) horses, and were mild in 50 (34%), moderate in 16 (11%), and severe in 11 (7%). Heart rate ranged from 30 to 86 beats/min (median, 44 beats/min), and most horses had a decrease in gastrointestinal sounds. Transrectal palpation was used to identify the impaction location as being the pelvic flexure in 103 (70.1%) horses, colon on the left side in 30 (20.4%) horses, and colon on the right side in 14 (9.5%) horses. All 147 horses received fluids i.v. and nonsteroidal anti-inflammatory medications or sedatives, including flunixin meglumine (124 horses, 84.3%) xylazine hydrochloride (81, 55%), butorphanol (6, 0.04%), and detomidine hydrochloride (9, 0.04%). Duration of medical treatment required to resolve the impaction ranged from 1 to 6 days (mean, 2 days). In addition to medical treatment, 24 (16.3%) horses also required surgery.(ABSTRACT TRUNCATED AT 250 WORDS)

This study reviews the medical records of horses diagnosed with large colon impaction between 1985 and 1991. The aim is to better understand the demographics, diagnosis, and potential treatments for this common equine illness, which represents 13.4% of all colic cases within the study population.
Population and demographics of the study
- The study reviewed medical records of 1,100 horses with colic, where 147 cases (13.4%) were confirmed to have large colon impaction.
- The affected population comprised more female horses (62.6%) with ages ranging from 1 year to 29 years, where the average (median) age of diagnosed horses was 7.1 years.
Diagnostic measures and findings
- Seventy horses arrived not exhibiting visible signs of abdominal pain. While 50 horses showed mild signs, 16 demonstrated moderate signs and 11 displayed severe signs.
- On admission, the heart rate of the horses ranged from 30 to 86 beats per minute, where the median was 44 beats per minute.
- Most horses showed a decrease in gastrointestinal sounds, an indicator of gut slowdown usually associated with abdominal issues, including large colon impaction.
- Transrectal palpation was used in the diagnosis with the pelvic flexure identified as the most common location of impaction (70.1%), followed by colon on the left side (20.4%) and colon on the right side (9.5%).
Treatment methods and outcomes
- All 147 horses received intravenous fluids alongside non-steroidal anti-inflammatory drugs or sedatives, including flunixin meglumine (used in 84.3% of cases), xylazine hydrochloride (55% of cases), butorphanol (0.04% of cases), and detomidine hydrochloride (0.04% of cases).
- The duration of the medical treatment required to resolve impaction ranged between 1 and 6 days, with an average of 2 days.
- Of the total, 24 horses (or 16.3% of the cases) required surgery in addition to the medical treatment.
