Background and aims: In a pilot study the semi-quantitative classification of intestinal wall vascularisation as proposed by Limberg was evaluated.

Patients and methods: 20 patients with confirmed Crohn's disease and clinical activity (10 male, 10 female, mean age 30.0 +/- 7.72 years, range 21 - 49 years, mean time since onset of disease 4.6 years, range 0 - 15 years) were included. CDAI, CRP, ESR, and the blood count were evaluated. Two and six weeks after inclusion into the study these examinations were repeated. All patients were treated with anti-inflammatory drugs. The intestinal wall thickness was measured with ultrasound. The vascularisation following the Limberg classification and the number of blood vessels per square centimetre were assessed in the power-Doppler mode.

Results: The mean length of bowel segments with increased wall thickness (> 3 mm) at the beginning of the study was 20.3 cm (range 5 - 50 cm), the mean intestinal wall diameter 5.9 mm (range 4 - 9 mm). The mean density of blood vessels in the power-Doppler mode was 3.8 vessels/cm (2) (range 0 - 8 vessels/cm (2)), the median of Limberg levels was 2 (range 1 - 4). The density of blood vessels per cm (2) well correlated with the Limberg classification throughout the study (r = 0.2 at start; r = 0.94 at 1st follow-up; r = 0.91 at 2nd follow-up).

Conclusion: The classification for measuring intestinal wall vascularisation semi-quantitatively (as proposed by Limberg) proved to be easily applicable in routine sonography. Besides the measurement of intestinal wall thickness, activity indices, clinical and laboratory parameters, it may constitute an additional means for evaluation of disease activity.
