Wickett, an elderly cat, had progressive constipation and needed enemas every 2-3 weeks. We removed the lion’s share of his colon at our state-of-the-art practice in Burton-Upon-Trent, and he’s now recuperating. Early indications are good; these surgeries carry a significant perioperative mortality rate.
The colon is simply water reabsorption and faecal storage system, so losing it doesn’t affect digestion and absorption. Saving the valve between the small and large intestines helps keep the faecal consistency manageable post-op.
