A team of surgeons in China have beat the odds to removes 13 kgs of large intestines from a 22-year old man suffering from Hirschsprung disease – a rare condition which caused severe constipation to build up in his colon over the years. The unnamed patient is thought to have been born with the Hirschsprung disease (HD) – a developmental disorder characterised by the absence of ganglia in the distal colon, resulting in a functional obstruction. This means the nerves that control the bowels and help them to squeeze and relax to push stools out, are missing – leading to a build up and an eventual blockage.
