The caecum is involved in many surgical conditions such as carcinoma of caecum, lipoma of Caecum and volvulus of caecum. In spite of availability of modern diagnostic investigations, abdominal emergencies diagnosis mainly depends on clinical examination skills of the surgeon, who requires through knowledge of human anatomy; hence the present work is aimed to study the Caecum, its interior and arterial supply. Material and methods: Study includes 78 specimens, the dead foetuses (62) are obtained from labour rooms of the department of Obstetrics & Gynaecology, Government General Hospital and adult cadavers(16) are from dissection hall, Guntur medical college, Guntur. Results: Position of caecum in fetuses is mostly in the right lumbar region (70.96%) in some it is subhepatic, right iliac fossa and umbilical positions. In adults bodies it is in right iliac fossa 87.5%, and in 12.5% in the right lumbar region. Two fetuses showed Jackson’s veil. In 9.67% of fetal specimens the anterior caecal artery is arising directly from the inferior division of ileo- olic artery and in 1.61% anterior caecal artery is directly arising from ileal artery. In 6.45% fetal specimens, posterior caecal artery is arising directly from inferior division of ileo-colic artery and in 3.22% it is arising directly from ileal artery. In 1.61% it is arising directly from colic artery. Conclusion: The present study of caecum showed variations from the literature available in position and arterial supply. These findings may help the surgeons in avoiding the complications while performing the abdominal surgeries.
