Abstract

: Studies about histological changes in small intestine are still very limited. This study was aimed to obtain the histological changes of the small intestine in several time intervals during 24 hours postmortem. This was a descriptive observational study using domestic pig as model. Samples were obtained from the ileum section of the small intestine, taken at 0 hour, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 9 hours, 12 hours, 14 hours, 16 hours, 18 hours, 20 hours, 22 hours, and 24 hours postmortem. The results showed that the earliest histological change was identified at 0 hours postmortem as congestion of the intestinal glands and formation of subepithelial cell spaces, followed by destruction of basal membranes of the glands at 3 hours postmortem, lysis of the glands at 16 hours postmortem. At 18-24 hours postmortem, almorst all intestinal glands could not be identified. Conclusion: The earliest histological change of small intestine was identified at 0 hours postmortem as congestion of the intestinal glands, followed by necrosis of the glands at 3 hours postmortem, and lysis of the glands at 16 hours postmortem
