ABSTRACT
Objective Patients with severe acute pancreatitis ( SAP) always suffer decrease in gastrointestinal motility , even gastrointestinal failure.The article aimed to investigate the changes of vasoactive intestinal peptide (VIP) in the myenteric plexus of the gastric antrum in rats with severe acute pancreatitis ( SAP) complicated by gastrointestinal dysmotility . Methods Twenty Sprague Dawley rats were randomly allocated into two groupscontrol group and SAP group .Acute pancreatitis was induced by intraductal infu-sion of 5%sodium taurodeoxycholate .24 h after operation , records were made on pathological evaluation of pancreatic lesion , amylase, C-reactive protein ( CRP) , gastric emptying rate and the percentage of VIP neurons in the total neurons . Results Compared with the control group, the gastric emptying rate in the SAP group was significantly lower ([31.49 ±3.96]% vs [70.99 ±1.82]%).The score of pancreatic lesion, amylase, CRP and the percentage of VIP neurons was significantly higher ([14.63 ±1.06]score vs [1.60 ± 0.52]score, [2061.25 ±434.86]U/L vs [360.20 ±30.29]U/L, [140.10 ±17.07]μg/mL vs [35.71 ±6.43]μg/mL, [22.45 ± 4.10]%vs [10.72 ±1.92]%)(P<0.05). Conclusion Plas-ticity took place in VIP neurons in the myenteric plexus of gastric an-trum in rats with SAP complicated by gastrointestinal dysmotility , which was connected with neural mechanism underlying SAP compli-cated by gastrointestinal dysmotility .
