Detection of intestinal ischemia in patients with acute small-bowel obstruction due to adhesions or hernia: efficacy of CT.

Abstract

OBJECTIVE.The purpose of this study was to determine whether CT can be used to diagnose ischemia of the small intestine in patients with small-bowel obstruction due to adhesions or hernia. SUBJECTS AND METHODS. During

The role of D-dimer in the diagnosis of strangulated small-bowel obstruction

“…Ultrasonography (US) and computer tomography (CT) are promising tools, but their definitive role in the diagnosis of strangulated obstruction has still to be established (16)(17)(18)(19). Some biochemical markers have been used for the diagnosis of mesenteric ischemia (20)(21)(22).…”

A Case of Trans-Omental Hernia: An Incarcerated Bowel Condition Detected by Computed Tomography

“…The development of CT has led to improved diagnostic accuracy for strangulated bowels [5]. Balthazar et al [4] reported a diagnostic accuracy of 60%.…”

“…Balthazar et al [4] reported a diagnostic accuracy of 60%. Frager et al [5] showed that CT can accurately detect intestinal ischemia based on the presence of bowel wall thickening and high attenuation of contrast enhancement. In our case, there was small bowel wall thickening and high attenuation of contrast enhancement, as well as swelling of the intestinal mesentery.…”

CT differentiation between necrotic and nonnecrotic small bowel in closed loop and strangulating obstruction

“…According to the literature [5][6][7][8][9][10][13][14][15], we selected the following six CT findings for the statistical analysis: bowel dilatation of strangulated loops (bowel dilatation), wall thickening of strangulated intestines (wall thickening), ascites, vascular dilatation of affected mesenteries (vascular dilatation), elevation of mesenteric attenuation (mesenteric attenuation), and radial distribution of the mesenteric vessels (radial distribution). We graded these findings by assigning the discrete categories shown in Table 1.…”

“…Several investigators have reported the findings of computed tomography (CT) in closed loop and strangulating obstruction [2][3][4][5][6][7][8][9][10][11][12][13]. The first objective of abdominal CT in patients with bowel obstruction is to evaluate the need for emergency surgery.…”
