Chronic intestinal pseudo-obstruction (CIPO) is a very rare syndrome with chronic and recurrent symptoms that suggest intestinal obstruction in the absence of any mechanical blockage of the lumen. [3] The most common symptoms of CIPO include abdominal pain, constipation, nausea, vomiting, dysphagia, and abdominal distention.
Small intestinal bacterial overgrowth (SIBO), also termed bacterial overgrowth, or small bowel bacterial overgrowth syndrome (SBBOS), is a disorder of excessive bacterial growth in the small intestine. Unlike the colon (or large bowel), which is rich with bacteria, the small bowel usually has fewer than 100,000 organisms per millilitre. [1]
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.
Intestinal pseudo-obstruction (IPO) is a clinical syndrome caused by severe impairment in the ability of the intestines to push food through. It is characterized by the signs and symptoms of intestinal obstruction without any lesion in the intestinal lumen. [ 1 ]
Bowel obstruction, also known as intestinal obstruction, is a mechanical or functional obstruction of the intestines which prevents the normal movement of the products of digestion. [2] [5] Either the small bowel or large bowel may be affected. [1] Signs and symptoms include abdominal pain, vomiting, bloating and not passing gas. [1]
Initial management involves fluid resuscitation and potentially nasogastric suctioning. [1] Since gallstone ileus constitutes a form of mechanical small bowel obstruction, it can be a surgical emergency and requires open or laparoscopic surgery to remove an impacted stone. [1]
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, colonic obstruction may manifest as gaseous distention of the colon, but ...
On CT imaging, the small bowel feces sign appears as a mottled, mixed-density pattern within a distended small bowel loop. It is typically located proximal to the site of obstruction and is often accompanied by other features of small bowel obstruction, such as: [5] Dilated bowel loops: Loops proximal to the obstruction exhibit dilation (>2.5-3 ...
