methylcellulose and Intestinal-Obstruction

Adhesive bowel obstruction is one of the most frequent complications after radical cystectomy, prolonging hospital stay and fasting period and increasing medical expenses. This study evaluated the effectiveness of hyaluronic acid/carboxymethylcellulose (HA/CMC) in preventing adhesive bowel obstruction after laparoscopic radical cystectomy.. Randomized, controlled, single-blinded study was performed. Of 76 patients who underwent laparoscopic radical cystectomy for bladder cancer, 38 received HA/CMC instillation and 38 did not. The primary endpoint was the rate of postoperative adhesive bowel obstruction. The secondary endpoint was the rate of other postoperative outcomes.. None of the patients who received HA/CMC instillation experienced postoperative adhesive bowel obstructions, compared with six (15.79%) patients in the control group (p = 0.025). Of the six patients with ileus, two underwent adhesiolysis. There were no significant differences between the two groups in other postoperative outcomes.. HA/CMC instillation during laparoscopic radical cystectomy may reduce the incidence of postoperative adhesive bowel obstruction without adverse effects.

To compare small bowel lesions, especially stenoses, with conventional enteroclysis, static MRI and dynamic MR-enteroclysis.. Forty-two patients with Crohn's disease or other suspected small bowel lesions were examined. MRI was performed in a static and a dynamic way either within one hour after conventional enteroclysis (n = 30) or a few days afterwards (n = 12). In order to monitor bowel filling and to characterize stenoses in a dynamic fashion, 4 series of coronal T2w HASTE breath hold sequences were used, first without additional bowel opacification and then during administration of 1,5 l methyl cellulose via a naso-intestinal tube in the MR unit. Intravenously applied Buscopan was used to reduce bowel movement.. In 4 out of 42 Patients, application of methylcellulose was limited to 1000 ml because of gastrointestinal complaints or visible gastral reflux. All patients could be evaluated. Static MRI performed within one hour after conventional enteroclysis and no additional bowel opacification showed insufficient bowel distension. Distension was still better than in MRI without prior application of contrast medium. On the contrary, dynamic MR - enteroclysis lead to controlled and complete bowel distension which allowed for significantly better evaluation of normal bowel anatomy and pathological alterations of the gut. Because of a better bowel distension and dynamic evaluation, MR-enteroclysis revealed significantly more stenoses (n = 42) than MRI obtained with less distension (n = 27, p < 0.001), and characterization of lesions was comparable to conventional enteroclysis (p < 0.001). Fixed and non-fixed stenoses could be differentiated by dynamic MR-enteroclysis. Furthermore, extraluminal complication of Crohn's disease such as abscesses and fistulae or large bowel manifestation of disease were shown in 13 patients.. Dynamic MR-enteroclysis is feasible in routine diagnostic work-up of the small bowel. It is superior in depicting intra- and extraluminal manifestation of small bowel lesions and enables characterization of stenoses comparable to conventional enteroclysis.

Spiral computer tomography (SCT) became an important supplement to the Sellink examination. Multi slice computer tomography (MSCT) achieves a z-axis resolution of 1-2 mm without considerable increase in the acquisition time. In this paper, examination technique in first clinical results of CT-Sellink examination with MSCT, including the 3D-reconstruction are presented.. The investigations were carried out with the Somatom Plus 4 Volume Zoom (Siemens, Forchheim) scanner. The following parameters were employed: 4 parallel detector ledges, collimation 4 x 1 mm, tube power 140 mA, tube voltage 120 kV, pitch 5 up to 6 mm, slice thickness 1 mm and 2 mm, reconstruction with 50% overlap. Via a duodenal tube, the small intestine was distended by means of 1.5 up to 2.5 l methyl-cellulose suspension. The data were acquired 35 s after injection of 120 ml contrast media (Ultravist). Various methods of postprocessing were applied on a workstation.. As of yet, 16 patients were examined with MSCT-Sellink. In 4 cases pathological findings were detected with MSCT-Sellink, which were not recognized with X-ray Sellink.. Due to high z-axis resolution and short acquisition time, the morphological details of the small intestine can be visualized utilizing MSCT-Sellink. The data set is well suited for 3D postprocessing. Improvement of diagnostic accuracy can be anticipated.

An analysis of the records of 300 patients who had had 370 small-bowel radiologic examinations and a subsequent 102 patients examined by fluoroscopy and enteroclysis suggests that enteroclysis (small-bowel enema) is extremely valuable in the radiologic evaluation of small intestinal disease. Our results suggest that best results are obtained if the radiologist spends adequate time to participate in and observe the studies carefully. We believe that the fluoroscopic observation of low-density barium passing through distended small bowel gives a much clearer picture of its status than routine follow-through examinations. Disagreement exists concerning the choice of Sellink's method, using dilute barium, and Herlinger's technique, using a somewhat denser barium followed by methylcellulose. We prefer the latter. Enteroclysis probably should not be done in the presence of a high small-bowel obstruction because of the danger of reflux and aspiration. If intubation is unsuccessful, an oral study should be postponed until the effects of the topical anesthesia disappear. A controlled prospective study of the accuracy of fluoroscopic enteroclysis versus a good detailed independent follow-through examination is needed.

The value of double contrast small bowel enema via duodenal intubation using barium sulphate and methylcellulose as contrast media was assessed in 250 patients. In cases of small bowel obstruction it represented the first-line investigation after a plain abdominal film. It was performed electively in patients of painful bowel syndrome, in cases of malabsorption, in cases of endoscopically or radiologically diagnosed colitis and in patients with Crohn's disease. On the basis of our results we believe double contrast small bowel enema to be the most reliable investigation in the localization and identification of small bowel lesions.

A modification of the small-bowel enema with barium and methylcellulose is described and findings in 300 consecutive examinations compared with the clinical diagnoses. The radiograph was positive in 37% of cases and the clinical examination in 29%. Diseases and abnormalities of the small bowel, including motility disorders, can be diagnosed with high sensitivity and specificity using this technique.
