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.

One review stated that the most common causes of disruption to the defecation cycle are associated with pregnancy and childbirth, gynaecological descent, or neurogenic disturbances of the brain-bowel axis. [44] The pathophysiologic mechanisms are thought to be different in obstructed defecation compared with slow transit constipation. [43]
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 ...
