Megacolon

By Debbie “The Rat Lady” Ducommun

 

For the treatment of megacolon see the article at www.ratfanclub.org/megacolon.html

 

Here are photos of autopsies done on rats with megacolon.

 

WARNING!  They are quite graphic and might be disturbing to some people.

 

 

These rats were a brother and sister from an extremely inbred litter.  They were euthanized at about 4 weeks of age.  Their large intestines were about 3-4 times the size they should have been.

 

 

 

 

 

 

The neutered male rat below was 9 months old and received the recommended treatment.  However, he developed a blood clot in his large intestine which caused severe symptoms and he was euthanized. The abnormally enlarged portion of his large intestine was about 4 times normal size.

 

 

 

The female rat below was about 6 months old and received some treatment.  However, she developed a severe fecal blockage and was euthanized.  The enlarged portion of her large intestine is about 4 times normal size.  The fecal mass in the picture on the right is what caused her blockage. 4 ½ cm is about 1 ¾ inches.
