Morphology of Caecum in Human Fetuses at Different Gestational Ages
Journal Title: International Journal of Contemporary Medical Research - Year 2018, Vol 5, Issue 4
Abstract
Introduction: Limited information is available on developmental morphology of human fetal caecum. Embryologically, the caecal swelling appears as a small conical dilation of the caudal limb of primitive intestinal loop and it is the last part of the gut to return in the abdominal cavity. During rotation of gut it is located in the right upper quadrant below the right lobe of the liver. From here it descends into the right iliac fossa. The present study aims to locate the position and shape of caecum at different gestational ages of fetuses. Material and methods: Thirty eight human fetuses (n=38) of 11-40 wks gestational ages were procured from Dr. Sushila Tiwari Memorial Hospital, Haldwani. Fetuses were dissected, illeocaecal region was displayed. The position and shape of caecum were recorded in situ.Out of 38 fetuses caecum was conical in 19 fetuses.Quadrangular in 10 fetuses and in 9 fetuses caecum is right saccular. Position of caecum was right subhepatic in18 fetuses, right lumber in 15 fetuses and right iliac fossa in 5 foetuses. Results: The location of caecum in relation to abdominal regions presented higher incidence of subhepatic position in less than 30 weeks fetuses and right iliac fossa position in more than 30 weeks fetuses. With increasing gestational age position of caecum changes from right subhepatic position to right iliac fossa. Fetuses belonging to less gestational ages, caecum was conical in shape, however as the gestational age is increasing, caecum was noticed as quadrangular and right saccular in shape. Conclusion: The observations are in favor of developmental process on the localization of caecum.
