Megacolon in cats causes extreme constipation and suffering, with medical management providing relief in early cases and surgical colectomy being the most effective long-term treatment.
Megacolon causes severe suffering through complete inability to defecate. Cats with impacted colons strain repeatedly without result, experiencing abdominal pain from distension and pressure. The need for repeated anesthetic manual deobstipation procedures causes repeated distress and anesthetic risk. Without definitive treatment, the cycle of impaction and deobstipation continues indefinitely with worsening welfare. Subtotal colectomy is a life-changing procedure for severely affected cats - though the post-operative period requires adjustment to softer, more frequent stools, the relief from chronic impaction dramatically improves quality of life. Owners often describe the transformation as remarkable.
