Radiation proctitis or radiation proctopathy is a condition characterized by damage to the rectum after exposure to x-rays or other ionizing radiation as a part of radiation therapy. [1] Radiation proctopathy may occur as acute inflammation called "acute radiation proctitis" (and the related radiation colitis) or with chronic changes ...
Radiation colitis is injury to the colon caused by radiation therapy. It is usually associated with treatment for prostate cancer or cervical cancer . [ 1 ] Common symptoms are diarrhea , a feeling of being unable to empty the bowel , [ 2 ] gastrointestinal bleeding, and abdominal pain.
Endoscopic therapies including argon plasma coagulation have been used for bleeding telangiectasia in radiation proctitis and at other intestinal sites, although there is a rick of perforation. [2] Surgical treatment may be needed for intestinal obstruction, fistulae, or perforation, which can happen in more severe cases. [12]
Depending on the level of obstruction, bowel obstruction can present with abdominal pain, abdominal distension, and constipation.Bowel obstruction may be complicated by dehydration and electrolyte abnormalities due to vomiting; respiratory compromise from pressure on the diaphragm by a distended abdomen, or aspiration of vomitus; bowel ischemia or perforation from prolonged distension or ...
Ogilvie syndrome, or acute colonic pseudo-obstruction, is the acute dilatation of the colon in the absence of any mechanical obstruction in severely ill patients. [ 1 ] Acute colonic pseudo-obstruction is characterized by massive dilatation of the cecum (diameter > 10 cm) and right colon on abdominal X-ray.
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 ...
Types of mesenteric ischemia are generally separated into acute and chronic processes, because this helps determine treatment and prognosis. [3] Bowel obstruction is most often caused by intestinal adhesions, which frequently form after abdominal surgeries, or by chronic infections such as diverticulitis, hepatitis, and inflammatory bowel disease.
Stercoral ulcer is an ulcer of the colon due to pressure and irritation resulting from severe, prolonged constipation due to a large bowel obstruction, damage to the autonomic nervous system, or stercoral colitis. It is most commonly located in the sigmoid colon and rectum.
