Imagine two decades of never being able to fully relieve yourself in the bathroom.

That was the experience a 22-year-old Chinese man lived with before doctors in Shanghai removed 30 inches of his extremely swollen colon. Weighing nearly 29 pounds, his colon was filled with feces that had accumulated there over his lifetime. He told doctors that he?d suffered constipation for his entire life, and that laxatives only offered minor relief. Doctor Yin Lu of Tenth People?s Hospital of Shanghai, where the surgery was performed, told Chinese news site The Paper that the man?s abdomen looked as if he was more than nine months pregnant.

?It looked like it could explode at any time,? said Doctor Lu… At the end of a 3-hour operation, doctors had successfully removed the affected portion of his colon ? as well as the massive accumulation of poop ? and he is expected to recover.The anonymous man?s painful blockage resulted from a condition known as Hirschsprung?s disease. This congenital condition ? characterized by poor movement in the bowels ? occurs when portions of a person?s bowel are missing nerve cells.

A person?s digestive tract typically moves food and waste through the intestines with a process known as peristalsis: involuntary waves of muscle contractions that push stuff through. But for a person with Hirschsprung?s disease, peristalsis halts at the portion of the bowel where there aren?t nerve cells.

Because there are no nerve cells to signal muscles to move, a person?s feces simply ends up sitting there, causing uncomfortable constipation, which can lead to megacolon and an infection called enterocolitis…

I don’t think I will ever complain about being constipated again.
