Pathological Aneurysm

Colonic hypertrophy is a common condition in children due to birth, but can also be seen in adults due to intoxication. Complications of a bulge of the colon are quite dangerous, so it should be discovered and timely interventions to avoid the risk of bad happening.
What is colon enlargement?
Megacolon is an abnormal enlargement of the colon that is not caused by mechanical obstruction. Accompanied by this abnormal expansion is paralysis of the normal peristalsis of the intestinal tract. When bowel motility is reduced, stool moves slowly and drains out of the colon, making it much stiffer and unable to drain

. For a long time, stool kept accumulating, causing the colon to swell.
The common symptoms of this condition are initially abdominal discomfort, but can lead to more serious complications such as perforation of the colon, peritonitis or sepsis if left untreated.

The cause of colon enlargement
Colonic hypertrophy can be classified as acute or chronic depending on whether the dilation is temporary or ongoing All cases of acute hypertrophy are caused by external factors, while chronic aneurysm may be congenital or an external effect.




In addition, acute enlarged colon may be further classified depending on whether the patient has colitis or not. If the colon is inflamed, this situation will lead to intestinal aneurysm (Toxic Megacolon). If there is no inflammation, then there is simply the usual acute aneurysm.
Therefore, the cause of an enlarged colon corresponds to the division of the form of an enlarged colon due to congenital factors or external factors.
Natural
Congenital aneurysm, also known as congenital colonic lymphadenopathy, or Hirschsprung's disease The cause of the disease may be due to a family history of genetic factors or a genetic mutation.
Congenital aneurysms occur when nerve cells in the colon do not form completely. The nerves in the colon control muscle contractions that move food through the intestines Without contractions, the stool remains in the large intestine and it is not possible to defecate to excrete it.



Boys often have a higher incidence of hypertrophy than girls.
Due to external factors
In addition to the congenital cause of colon enlargement, some external factors such as antibiotics, intoxication, and other pathologies also cause the colon to expand abnormally.
Poisoned
One of the causes of intestinal aneurysm poisoning is due to inflammatory bowel disease (IBD). Inflammatory bowel disease causes swelling and irritation in parts of the digestive tract. These diseases can cause pain and damage to the large intestine such as ulcerative colitis or Crohn's disease. In addition, colon intoxication can also be caused by infections like Clostridium difficile caused by colitis or by parasitic infections like Trypanosoma cruzi (commonly known as Chagas disease).
Antibiotics
Using certain drugs such as Morphin, Risperidone, Codeine can also cause side effects that cause the colon to dilate.
Another factor
Some conditions can lead to colonic hypertrophy such as brain atrophy, spinal cord injury, chronic constipation, skin sclerosis, etc.

Symptoms are common when colon enlargement
For children
Hirschsprung changes according to the severity of the condition. Usually the signs and symptoms appear right after birth, but sometimes in some cases there will be no clear signs until the child is older.
Usually, the most obvious sign in a newborn is not having a bowel movement within 48 hours after birth. In addition, other signs and symptoms in a newborn may include:
Swollen abdomen;
Vomiting, vomit may be green or brown;
Constipation or miasma, which can make babies cry;
Diarrhea.
For older children, signs and symptoms may include: a swollen stomach, prolonged constipation, a child cannot defecate on his own, and has to be removed, the stool is black and always tired. , poor physical development.
For adults
Common signs of an aneurysm in adults are persistent constipation, abdominal pain, bloating, etc.
In case of intestinal aneurysm, symptoms of the condition may appear suddenly and include: abdominal pain, bloating, fever, fast heart rate leading to shock, bloody diarrhea, etc.




Diagnosis of aneurysm
In addition to relying on the aforementioned symptoms, colon aneurysm can be correctly diagnosed in the following ways:
X-ray: Through X-ray techniques using contrast material in the patient's abdomen, doctors can see the contrast of the narrow intestine and the enlarged intestinal segment through the image;
Biopsy tissue sampling: Doctors conduct a sample of colon tissue to be tested.
