Gastrointestinal motility and transit times in patients with liver cirrhosis and in healthy controls
Patients with cirrhosis Healthy controls p
Gastric emptying time (minutes) 23 (5–131) 29 (11–182) 0.43
Magnet velocity during first 2 hours in the small intestine (meters/hour) 1.27 (0.82–2.68) 1.00 (0.46–1.88) 0.03
Magnet velocity during first 4 hours in the small intestine (meters/hour) 0.95 (0.60–1.79) 0.75 (0.30–1.34) 0.06
Total gastrointestinal transit time (days) 1.6 (0.5–2.9) 2.0 (1.0–3.9) 0.33
Duration of time in the small intestine with fast movements (minutes) 8 (3–18) 6 (2–14) 0.16
Distance travelled during fast movements during the first 4 hours (meters) 1.97 (1.28–4.98) 1.47 (0.27–3.23) 0.04
Duration of time in the small intestine with slow movements (minutes) 50 (19–87) 38 (10–76) 0.45
Distance travelled during slow movements during the first 4 hours (meters) 1.27 (0.58–2.07) 0.89 (0.30–1.66) 0.05
Basic frequency of small intestinal contractions (contractions/minute) 9.5 (8.8–10.9) 9.8 (8.7–10.4) 0.18

The magnet pill moved faster through the upper small intestine in patients than in healthy controls. All data expressed as median (range).
