2024年10月13日 · Large bowel obstruction (LBO) is often impressive on imaging, on account of the ability of the large bowel to massively distend. This condition requires prompt diagnosis and treatment. Bowel obstruction may be complete or incomplete 6:

2016年3月2日 · In this chapter, you’ll learn how to recognize and categorize the four most common abnormal bowel gas patterns and their causes. These abnormal bowel gas patterns will appear the same whether imaged initially by conventional radiography or by CT scanning.

Large-bowel obstruction (LBO) differs substantially from small-bowel obstruction (SBO), and LBO is an abdominal emergency. Abdominal radiography can differentiate LBO from SBO. CT has become the standard imaging procedure for patients with both SBO and LBO.

2016年6月8日 · Differentiating between the small and large bowel on an abdominal X-ray is not always straightforward but there are a number of clues that may help you: The small bowel usually lies more centrally, with the large bowel framing it. The small bowel’s mucosal folds are known as valvulae conniventes and are visible across the full width of the bowel.

2019年2月12日 · Large bowel obstruction (LBO) occurs when there is mechanical obstruction of the large bowel and is often impressive on imaging on account of the ability of the large bowel to massively distend. This condition requires prompt diagnosis and treatment.

XR. Sensitivity of 69% to 80% for detecting bowel obstruction, but insensitive for diagnosing cause or location; Upright films can detect pneumoperitoneum, hollow viscus perforation; Distended colon (small bowel may appear distended as well if the ileocecal valve is competent)

As with all bowel obstructions, large bowel obstructions have three defining characteristics: partial or complete, intrinsic or extrinsic, benign or malignant. The work-up for a large bowel obstruction should focus on the etiology of the obstruction as well as severity.

Large-bowel obstruction (LBO) is a relatively common abdominal emergency. Computed tomography (CT) diagnosis of LBO is often easy, but it is essential to clarify LBO etiology and to decide how to treat it.

2018年11月8日 · Large-bowel obstruction (LBO) is much less common than small bowel obstruction but is considered an abdominal emergency. The etiology of bowel obstruction varies by age. In neonates, the most common causes include intestinal atresia, meconium ileus, Hirschsprung disease, and malrotation.
