2024年5月30日 · Colonic pseudo-obstruction can present with a sudden painless enlargement of the proximal colon accompanied by distension. Bowel sounds are normal or high-pitched, but should not be absent. Despite the absence of mechanical obstruction, patients can nonetheless go on to bowel necrosis and perforation (especially if dilatation is severe) which ...

2023年7月3日 · Intestinal pseudo-obstruction is characterized by the dilation of bowel in the absence of an anatomical obstruction. Patients present with the signs and symptoms of bowel obstruction, including nausea, vomiting, abdominal distension, and obstipation with bowel dilation on x-ray or CT imaging. Pseudo-obstruction can be acute or chronic.

2024年3月6日 · Acute colonic pseudo-obstruction (ACPO) is a functional bowel obstruction characterised by colonic dilatation in the absence of mechanical obstruction on imaging. Complications include bowel ischaemia, perforation and death.

Varying amounts of small intestinal dilation and air-fluid levels. Cecal diameter > 10–12 cm associated with increased risk of colonic perforation. CT scan to exclude distal colonic obstruction, if suspected. Assess cecal size by abdominal radiographs every 12 hours + + +

Chronic intestinal pseudo-obstruction (CIP) is a rare, chronic disorder of the luminal gas-trointestinal tract. Symptoms and signs suggest a mechanical bowel obstruction, although in the evaluation of patients with CIP, both routine and specialized tests fail to identify evidence of mechanical obstruction.

The appearance of polyhydramnios and dilated bowel loops on prenatal sonographic examination usually implies mechanical obstruction. The prognosis is variable, depending on the etiology. Congenital pseudo-obstruction, a potentially lethal disease, comprises a group of disorders characterized by inte …

2021年10月20日 · Commonly, there are five characteristics or signs on POCUS that diagnose and stage SBO: the presence of dilated bowel (> 2.5 cm) (Figure 3A, ,B); B); abdominal A-lines (gastrointestinal intraluminal air) (Figure 4A); abnormal bowel peristalsis (Supplementary Video 1); interloop free fluids (Figure 4C); and thickened bowel wall (> 3 mm) (Figure ...

2021年3月1日 · Comparative quantitative assessment of global small bowel motility using magnetic resonance imaging in chronic intestinal pseudo-obstruction and healthy controls

2023年6月2日 · In patients with suspected pseudo-obstruction, the main differential to consider is a mechanical large bowel obstruction, such as from an obstructing colorectal cancer or diverticular stricture. Other differentials include a toxic megacolon or paralytic ileus (of the small bowel).

2007年1月24日 · Ultrasonography showed severe polyhydramnios with a deepest amniotic fluid pocket of 19 cm and multiple loops of dilated small bowel with visible peristalsis and no ascites or bowel-wall thickening. The scan was otherwise normal. Small bowel obstruction was suspected and the patient was counseled accordingly.
