Cecal volvulus radiology

When seen on conventional radiographs or tomograms, the cecal volvulus is seen as a rounded focal collection of air-distended bowel with haustral creases in the left upper quadrant that resembles a coffee bean (Figs. 2A, 2B, 2C and 3A, 3B). Ileocolic vascular curvature and ectopic cecal location were the only features independently and significantly associated with cecal volvulus in multivariable regression (odds ratio 178, p = 0.014, and 63, p = 0.013, respectively) and also the only features with both sensitivity (12/14 [85.7%, 95% CI 57.2-98.2%] and 13/14 [92.9%, 95% CI 66.1-99 Radiology Masterclass 'Caecal Embryo Sign' In caecal volvulus, the dilated caecum takes on a shape similar to a mammalian embryo. That is, the formation of a large dilated caecal pole (head), with one or two further 'segments' (body and tail). This is seen in all the images on this page. Cecal Volvulus.

Bundschuh (7) collected 110 cases of cecal volvulus in 1913. For the period 1913–42, Wolfer, Beaton, and Anson (63) collected 194 cases, bringing the total to 304. Courty (11) cites an additional 75 examples from France since 1940, and a review of the readily available sources in the American and British literature since 1942 has yielded 68 cases.

© RSNA, 2010 Cecal volvulus accounts for approximately 1 % of the intestinal obstruction. Etiology includes congenital development of fixation, secondary to adhesion, scarring or mass lesions. Two types of torsion are described: axial torsion and cecal bascule.

There is a variant of cecal volvulus termed a "cecal bascule" that occurs when the cecum folds anteriorly without any torsion. A cecal bascule is often seen as a

CT demonstrates the large bowel mass is a grossly distended food-filled cecum that is not in the right iliac fossa but in the left side of the abdomen. The axial slices clearly show the ileum passing through a 360-degree rotation to enter the On axial CT images, cecal volvulus is suggested by the extreme dilatation of the cecum. When seen on conventional radiographs or tomograms, the cecal volvulus is seen as a rounded focal collection of air-distended bowel with haustral creases in the left upper quadrant that resembles a coffee bean (Figs. 2A, 2B, 2C and 3A, 3B). Se hela listan på emedicine.medscape.com Cecal Volvulus. A volvulus always extends away from the area of bowel twist.

The two limbs of the looped obstruction gradually taper and converge at the site of the torsion, resulting in the appearance of a bird's beak. When cecal volvulus is suspected, the absence of distal colonic decompression on CT topograms makes the diagnosis very unlikely. Whirl, ileocecal twist, transition points, X-marks-the-spot, and split wall have high specificity for cecal volvulus. © RSNA, 2010 Cecal volvulus accounts for approximately 1 % of the intestinal obstruction.

When cecal volvulus is suspected, the absence of distal colonic decompression on CT topograms makes the diagnosis very unlikely. Whirl, ileocecal twist, transition points, X-marks-the-spot, and split wall have high specificity for cecal volvulus. The diagnosis of cecal volvulus is confirmed surgically (Figure 3) and right hemicolectomy is performed with uneventful post-operative recovery. Interestingly, a review of the patient’s imaging data retrieves an abdominal CT performed five years earlier, already showing a wandering long ectopic cecum with neither distention nor volvulus Cecal volvulus is due to the cecum twisting around the ascending colon thus leading to small bowel obstruction. A long narrow based mesentery predisposes to volvulus.

We reviewed the clinical histories of 11 patients diagnosed with cecal volvulus at endoscopy or surgery. All CT findings were significantly more common in patients with cecal volvulus (p < 0.01) other than mesenteric engorgement for reader 1 (p = 0.332).

duction rates in cecal volvulus achieved through use of colonoscopy are much lower than those achieved in sigmoid volvulus, and in patients with cecal volvulus, the recurrence rate exceeds 50% [1]. In patients with uncom-plicated cecal volvulus, surgical options in-clude cecopexy, which has a low rate of morbidity (0–8%) and volvulus recurrence.
