Abstract
BackgroundThe parasympathetic nervous system exerts and controls intestinal tone. Several studies have suggested that the coefficient of the R–R intervals (CVRR) is useful for evaluating the parasympathetic nervous system.ObjectivesThis study aimed to evaluate the relationship between gastrointestinal emergencies, specifically ischemic colitis (IC) and small bowel obstruction (SBO), and the autonomic nervous system.MethodsIn this retrospective study, a total of 13 patients with IC or SBO aged ≧65 years were analyzed. CVRR was measured in patients with IC and SBO and controls.ResultsCVRR averaged to 8.8% ± 2.5% in controls, 1.4% ± 0.4% in patients with IC, and 2.4% ± 1.0% in SBO groups (p < 0.001). CVRR was significantly lower in patients with IC and SBO than that in controls.ConclusionThe results of this study demonstrate the possibility that CVRR may serve as a clinical index for assessing the functioning of the parasympathetic nervous system in patients with IC or SBO.

Summary
Gut mobility is controlled by the autonomic nervous system. Gastrointestinal diseases such as irritable bowel syndrome (IBS) and paralytic bowel obstruction (BO) are caused by autonomic nervous dysfunction [1,2,3]. This study aimed to evaluate the relationship between gastrointestinal emergencies, ischemic colitis (IC) and small bowel obstruction (SBO), and the autonomic nervous system. A total of 13 patients with IC or SBO aged ≧65 years were analyzed. CVRR was measured in patients with IC and SBO and controls.
