If a child has recurrent constipation and bloating, we should go to the hospital for further examination to rule out the possibility of congenital megacolon. The diagnosis of megacolon requires objective examination methods such as barium enema X-ray, rectal anal canal manometry and rectal biopsy. If the diagnosis of megacolon is confirmed, timely treatment is required. The treatment of megacolon is divided into three types according to the situation: 1. Removing the diseased intestine as much as possible is the best treatment method and is also a radical surgery. Regarding the age of radical surgery: due to the continuous improvement of medical technology and nursing care, the gradual improvement and proficiency of surgical methods and techniques, especially the development of minimally invasive technology, the age of surgery has been advanced from 1-2 years old to the neonatal period. At present, there is a gradual tendency to complete the surgery in the neonatal period, which can reduce the occurrence of complications. 2, non-surgical treatment: mainly adapted to the physical condition of the child can not withstand the surgical blow or due to age or the technical conditions of the primary hospital, in order to maintain defecation and growth and development of treatment measures. Non-surgical treatment includes: inducing bowel movement (such as anal plugs with open cork or soap bars), anal dilation, bowel cleansing and Chinese medicine therapy. 3, enterostomy, enterostomy is in the non-surgical treatment is ineffective, and can not be implemented when the radical surgery transitional treatment measures. For example: the ineffectiveness of bowel cleansing, poor general condition is not suitable for radical surgery, small bowel colitis continues to worsen after systematic treatment; special needs, such as intestinal perforation, special types of megacolon, etc.
