Hirschsprung disease

Introduction Giant bowel disease means a large intestine or colon, which may be a congenital cause, or it may be a recurrent change caused by other diseases (such as enteritis caused by toxic megacolon). The incidence of congenital typhoid disease is about one in every 5,000 live births. There are more boys than girls, and the likelihood of having this disease in the family is about 7%. However, the rate of "long-length" cases is the same family. Up to 20%.

Cause

The disease is mainly caused by the lack of "nerve joints" in the muscles of the colon. After the baby is born, due to the congenital lack of ganglia, the large intestine can not normally squirm, so the contents of the intestines or feces are piled up at the front end of the "no nerve segment of the intestines", so that this "cerebral segment of the ganglion" slowly Expanded to form a "huge colon" due to too much deposit. Therefore, the section "Giant Colon" is ganglion and normal.

The clinical manifestation of jejunia is mainly constipation. It is often impossible to smoothly remove fetuses (about 94%) on the first day of life, which is different from normal newborns. After taking home from the hospital, these babies often have constipation (93%), and they are prone to bloating due to constipation. Because of bloating and eating, vomiting and vomiting (64%), these symptoms are easily mistaken for "milk powder is not good". "Baby abdominal distraction", "gastric esophageal reflux", etc. As the feces accumulate at the front end of the "no ganglion segment", the more piles are piled up, the more likely it is due to "bacterial hyperplasia" leading to enteritis and chronic diarrhea (26%), and very few are due to gravity, and pressure is solved. Some patients have uncontrollable feces, which are called "testaments" (only 3% of congenital giant bowel disease, and most of the remains are caused by acquired chronic conditions).

Differential diagnosis

Recurrent duplication of the rectum: the diagnosis of rectal repeat deformity has signs of intestinal obstruction, and the rectal examination can touch the mass. A double-chamber rectum can be found by colonoscopy and X-ray examination. The treatment procedure closes the proximal end of the excess rectum.

Hard fecal stone formed in the colon: symptoms of intestinal obstruction, due to frequent bowel movements, feces accumulate in the colon can form a hard fecal stone, or secondary megacolon, most of which affect growth and development, can also cause vaginitis or ascending infection Check the anus, common hip flat circle, shallow gluteal groove, no hole in the anus or only one trace, low deformity, the diagnosis can touch the blind end of the rectum. Fecal stone intestinal obstruction is a mechanical intestinal obstruction caused by intestinal feces, etc., and early diagnosis is difficult. In recent years, with the changes in dietary structure, the incidence rate has increased. In addition, with the aging of society, senile fecal stone colon obstruction is increasing. Older patients, due to the particularity of their pathophysiology, make the disease develop rapidly and the mortality rate is high. Many scholars have put forward the key points of early diagnosis and grasping the timing of surgery from the perspective of surgery.
