When it comes to chronic megacolon, dietary and pharmacological methods should be used to increase intestinal motility. Laxatives and enemas can be used to prevent stool retention, while a diet rich in fiber and fluid intake can help reduce constipation. However, some patients with severe constipation report that a high-fiber diet can cause more bloating and constipation. Constipation and constipation are two sides of the same coin.
Constipation is defined as infrequent and difficult evacuation of stools, but it doesn't necessarily mean a permanent loss of function. Many cats experience one or two episodes of constipation without further progression. Intractable constipation that is resistant to treatment is referred to as constipation. The term constipation implies a permanent loss of function. A cat is only considered constipated after several consecutive treatment failures.
Recurrent episodes of constipation or constipation may lead to megacolon syndrome. This article (not a study) describes the diagnosis and treatment of mega-colon secondary to chronic constipation in a 46-year-old patient. Surgical treatment is recommended for symptomatic patients with persistent constipation and clear evidence of distal colon dilation on radiological examination, as well as those with previous complications. Subtotal coletomy and ileoretal anastomosis may be considered for patients who don't respond to medical treatment, have slow transit time, and have no other functional cause of constipation such as pseudo-obstruction or pelvic floor obstruction. For those with mild to moderate constipation, treatment with osmotic laxatives (saline solution, lactulose, macrogol 3350) or emollients (mineral oil) is recommended, along with appropriate hygiene and dietary measures.
Biofeedback may not be effective for the etiology of colonic inertia in chronic megacolon, although it has been successful in treating functional outlet obstruction. In general, immediate treatment of outlet obstruction involves eliminating the underlying cause of the obstruction. Diagnosis and treatment of slow transit constipation complicated by megacolon in adults can be found in Zhonghua Wei Chang WaikeZazhi.
