“…Furthermore, the ability to accurately localize the adhesion site may be helpful when laparoscopic treatment of the adhesion is considered. In LBO, the differential diagnosis between tumoral stenosis and inflammatory stenosis is sometimes difficult [7]. Reformatting in a plane of the stenosis and colon immediately above it may be helpful for investigating the relationship between normal and involved colon (Fig.…”

Multidetector CT of bowel obstruction: value of post-processing

et al. 2005

The value of imaging in patients with suspicion of bowel obstruction is dependent on the ability to answer questions relevant to the clinical management of patients. Is there mechanical obstruction? Is it a small bowel obstruction (SBO) or a large bowel obstruction (LBO)? What is the transition point? What is the cause of the obstruction? What is the severity of the obstruction? The results of studies published more than 10 years ago using axial and single-slice helical CT gave rise to findings based on axial slices that enables CT to answer these different questions. With the recent advent of multislice CT, large numbers of thin sections can be generated with short image intervals, which is well suited to postprocessing. Postprocessing techniques include standard reformatting methods such as sagittal, coronal and oblique reformatting, curved reformatting, maximum and minimum-intensity projection, variable thickness viewing, and volume and surface rendering. This pictorial review illustrates the added value of postprocessing for answering different questions concerning patients with suspicion of bowel obstruction.

“…CT when associated with multiplanar reconstruction has a sensitivity of 83 %, specificity of 93 %, and an accuracy of 91 % in determining the presence of ischemic complications. [6][7][8][9] In addition, it helps to provide detailed information about the severity of obstruction from sources such as diverticular disease, obstructive masses, or internal hernias. CT is much more readily available and easier to order in most practices.…”

Introduction Traditionally, large bowel obstruction (LBO) has been managed as an operative emergency. Its causes and treatments are an important part of general surgical and colon and rectal surgery practices. Discussion While management has traditionally been emergent laparotomy with resection or removal of underlying pathology, newer methodologies and treatments over the last decade have required treating physicians to consider a number of other options, including nonoperative options such as stenting, when treating these patients. Conclusion Given these changes, treating a patient with LBO requires a thoughtful assessment and comprehensive understanding of underlying pathology, assessment of the patient's comorbidities and up-to-date knowledge of modern options for treatment.

“…6a, b Incarcerated crural hernia. Computed tomography shows a bowel loop passing through the left femoral canal, medially to the femoral vessels, and the hernia does not reach the superior part of the thigh however, contrast enema may be nondiagnostic because the patient could not hold the contrast or tolerate insertion of the rectal tube [19]. Additionally, the search for other more proximal tumors is difficult with contrast enema and the evaluation of the viability of the cecum is impossible.…”
