Aims:

To investigate the diagnostic accuracy of small bowel hydrosonography in the diagnosis of Inflammatory Bowel Disease.

Methods:

Sixty patients with suspected Inflammatory Bowel Disease were included. Following clinical assessment, patients were requested to fast for 6 – 8 hours, then a conventional ultrasound was performed. Then the patients were asked to ingest 1 litre of Mannitol 10% and a small bowel hydrosonography was done 30 minutes later. The procedure usually lasted 30 – 45 min. A convex array 5 MHz transducer was used followed by a high resolution linear array transducer 12 MHz. All abdominal quadrants were examined sequentially; the sonographer assessed the morphological and vascular aspect of the bowel wall and commented on the motility of the segments and perienteric tissue. The results of the small bowel hydrosonography were then compared to the results of the investigative techniques that lead to the definitive diagnosis, whether endoscopy, serology and/or imaging.

Results:

The preliminary diagnosis using hydrosonography was as follows: 28 cases (46.67%) were diagnosed as Crohn's disease, 9 cases (15%) as ulcerative colitis, 12 cases (20%) as small bowel tumors and in 11 cases (18.33%) a specific diagnosis could not be achieved. Following various investigational techniques, the definitive diagnosis of our patients was as follows: 31 cases (51.69%) were diagnosed as Crohn's disease, 8 cases (13.33%) were diagnosed as ulcerative colitis, 7 cases (11.67%) were diagnosed with small bowel tumors and in 14 cases (23.33%) no definite small bowel pathology could be recognized. Small bowel hydrosonography had a sensitivity of (95.65%), a specificity of (64.29%) and an overall accuracy of (93.75%)) for diagnosis of small bowel pathology.

Conclusions:

Hydrosonography has a high diagnostic accuracy in the preliminary diagnosis of Inflammatory Bowel Disease and with good preparation as well as experienced operators, it can serve as an initial tool of choice in screening for small bowel diseases.
