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:

2015年5月21日 · This review will focus on the most widely used imaging methods for the evaluation of LBO: radiography, contrast agent enema, and multidetector computed tomography (CT). The final portion of this review describes the major mimic of LBO, acute colonic pseudo-obstruction (ACPO).

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.

2020年9月1日 · Large bowel obstruction (LBO) is associated with high morbidity and mortality due to delayed diagnosis and/or treatment. MDCT has become the standard of care to identify the site, severity, and etiology of obstruction.

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.

2015年5月21日 · Acute complete large-bowel obstruction (LBO) is an abdominal emergency, and imaging with radiography, CT, and contrast agent enema are essential for identifying the cause of the obstruction and distinguish it from pseudo-obstruction; LBO commonly requires surgical or endoscopic decompression.

Abdominal radiography, MDCT, and contrast enema are the three commonly used imaging modalities in the evaluation of LBO. Abdominal radiograph is the first imaging performed in suspected cases of bowel obstruction and can diagnose LBO with a sensitivity and specificity of 84% and 72%, respectively. It can also help to differentiate LBO from SBO ...

2017年7月1日 · Abdominal radiography, MDCT, and contrast enema are the three commonly used imaging modalities in the evaluation of LBO. Abdominal radiograph is the first imaging performed in suspected cases of bowel obstruction and can diagnose LBO with a sensitivity and specificity of 84% and 72%, respectively.[3] .

2025年1月12日 · Colon cancer, diverticulitis, and sigmoid volvulus make up over 90% of large bowel obstructions (LBOs), but a wide spectrum of less common causes should be kept in mind (Verheyden et al. 2020). Both SBO and LBO can arise as the onset of an unknown neoplasm, a sign of advanced disease, or an iatrogenic complication (Scaglione et al. 2024).

2012年10月30日 · Large-bowel obstruction (LBO) is a relatively common abdominal emergency. The CT exam has become the most important imaging modality for the diagnosis of LBO, following abdominal ultrasound and plain radiography. The recent multi-detector CT (MD-CT) is able to clarify the etiology of LBO and to help in deciding how to treat LBO.
