Neurogenic bowel dysfunction (NBD) is reduced ability or inability to control defecation due to deterioration of or injury to the nervous system, resulting in fecal incontinence or constipation. [1] It is common in people with spinal cord injury (SCI), multiple sclerosis (MS) or spina bifida .
The signs and symptoms of colorectal cancer depend on the location of the tumor in the bowel, and whether it has spread elsewhere in the body ().The classic warning signs include: worsening constipation, blood in the stool, decrease in stool caliber (thickness), loss of appetite, loss of weight, and nausea or vomiting in someone over 50 years old.

Fecal impaction is a common result of neurogenic bowel dysfunction and causes immense discomfort and pain. Its treatment includes laxatives, enemas, and pulsed irrigation evacuation (PIE) as well as digital removal. It is not a condition that resolves without direct treatment.
neurons were strongly reduced all over the digestive tract; megacolon appeared only when there was a reduction of over 80% of the number of neurons these pathologies appeared as a result of the disruption of the neurally integrated control of peristalsis (muscular annular contraction) in those parts where a strong force is necessary to impel ...
Pancreatic cancer is the fifth most-common cause of cancer-related deaths in the United States, [8] and the seventh most-common in Europe. [9] In 2008, globally there were 280,000 new cases of pancreatic cancer reported and 265,000 deaths. [10] These cancers are classified as endocrine or nonendocrine tumors. The most common is ductal ...
The distinction helps to narrow the possible causes and treatment. Common causes of small bowel obstruction include post-operative adhesions, hernias, intussusception, and intraabdominal tumors. Common causes of colonic obstruction include primary colon cancer, volvulus and post-operative adhesions. When the ileocecal valve is competent ...
The number and location of the intestinal tumors are modified by unlinked genes. Many other models have since appeared, including a model of attenuated FAP (the 1638N model) and several conditional mutants that allow for tissue-specific or temporal ablation of gene function. For more information see mouse models of colorectal and intestinal cancer.
Human inflammatory bowel disease is a group of inflammatory conditions in the large and small intestine. It is well known that chronic inflammation in the colon can lead to cancer. There are genetic mouse models for inflammatory bowel disease associated colon cancer. Interleukin 10 knock out mice develop invasive adenocarcinoma in the colon. [25]
