Intestinal gas may reflect the function of the gut. Using plain abdominal radiographs, we investigated whether intestinal gas volume is related to AP. METHODS: Plain abdominal radiographs of 68 patients with AP within 24 hours after admission and 21 normal controls were digitized and transmitted to a computer. The region of intestinal gas was identified by an image manipulation software and the gas volume score (GVS) was calculated. The relationships between the GVS values and various clinical factors of AP were analyzed. RESULTS: The GVS in the AP group was 0.084±0.016, in the mild AP (MAP) group 0.070±0.005, and in the severe AP (SAP) group 0.094±0.013; all values were higher than that in the control group (P<0.01). The GVS in the SAP group was higher than that in the MAP group. The GVSs were correlated to the Ranson’s scores (r=0.762, P<0.01) and the acute physiology and chronic health evaluation II (APACHE II) scores (r=0.801, P<0.01). In addition, the GVS in patients with secondary pancreatic and/or peripancreatic infection was 0.107±0.014, higher than that in patients without secondary infection (P<0.01). GVS was not related to gender, age, etiology or clinical outcome of AP. CONCLUSIONS: Intestinal gas volume is significantly elevated in patients with AP. It is closely related to Ranson’s and APACHE II score and secondary pancreatic and/or peripancreatic infection. GVS may be a new prognostic tool for assessing the severity of AP in the early course of the disease.展开更多

Both central and peripheral factors, including psychosocial factors, abnormal GI motility and secretion, and visceral hypersensitivity, are thought to contribute to the symptoms of IBS. Several studies have demonstrated altered GI motor function in IBS patients and the pattern differs between IBS subgroups based on the predominant bowel pattern. Few studies have so far addressed GI secretion in IBS, but there are some evidence supporting altered secretion in the small intestine of IBS patients. Visceral hypersensitivity is currently considered to be perhaps the most important pathophysiological factor in IBS. Importantly, several external and internal factors can modulate visceral sensitivity, as well as GI motility, and enhanced responsiveness within the GI tract to for instance stress and nutrients has been demonstrated in IBS patients. Today IBS is viewed upon as a disorder of dysregulation of the so-called brain-gut axis, involving abnormal function in the enteric, autonomic and/or central nervous systems, with peripheral alterations probably dominating in some patients and disturbed central processing of signals from the periphery in others.展开更多
