Zusammenfassung
Zielsetzung: Im Rahmen einer prospektiven Pilotstudie wurde die von Limberg vorgeschlagene semiquantitative Klassifikation zur Bestimmung der Darmwandvaskularisation evaluiert. Patienten und Methode: 20 Patienten mit gesichertem Morbus Crohn im akuten Schub (10 Frauen, 10 Männer; Durchschnittsalter 30,0 ± 7,72 Jahre; Altersspanne 21 - 49 Jahre, durchschnittliche Krankheitsdauer 4,6 Jahre [Spannweite 0 - 15 Jahre]). Bestimmt wurden CDAI, CRP, BSG und ein Blutbild. Zwei und sechs Wochen nach Aufnahme in die Studie wurden die Untersuchungen wiederholt. Alle Patienten erhielten eine antiinflammatorische Therapie. Sonographisch bestimmt wurde die Darmwanddicke; im Power-Doppler-Modus wurden die Vaskularisation nach der Limberg-Klassifikation und die Gefäßzahl pro Quadratzentimeter bestimmt. Ergebnisse: Die durchschnittliche Länge der wandverdickten Darmsegmente (> 3 mm) bei Aufnahme betrug 20,3 cm (Spannweite 5 - 50 cm), die Darmwanddicke 5,9 mm (Spannweite 4 - 9 mm). Die Gefäßdichte lag im Power-Doppler-Modus im Mittelwert bei 3,8 Gefäße/cm2 (Spannweite 0 - 8 Gefäße/cm2), der Median der Limberg-Stadien bei 2 (Spannweite 1 - 4). Die Gefäßdichte in cm2 korrelierte zu allen Untersuchungszeitpunkten sehr gut mit der Limberg-Klassifikation (r = 0,82 - Aufnahme; r = 0,94 - 1. Kontrolluntersuchung; r = 0,91 - 2. Kontrolluntersuchung). Schlussfolgerung: Die von Limberg vorgeschlagene Klassifikation zur semiquantitativen Bestimmung der Darmwandvaskularisation erweist sich in der Routinesonographie als einfach anzuwenden und stellt neben der Darmwanddicke, Aktivitätsindizes, klinischen und laborchemischen Parametern möglicherweise ein zusätzliches Instrument für die Beurteilung der Krankheitsaktivität dar.
Abstract
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/cm2 (range 0 - 8 vessels/cm2), the median of Limberg levels was 2 (range 1 - 4). The density of blood vessels per cm2 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.
