Sub-hepatic Caecum with Extra-pelvic Looped Sigmoid Colon: An Embryological and Clinical Perspective

ABSTRACT

Introduction: We encountered variation in the placementof large intestine in abdominal cavity of a 76-years-old malecadaver during dissection of abdominal cavity. The workwas performed in Department of Anatomy during routineMBBS teaching sessions. The aim of this paper is to reportco-existence of error of mid-gut development and alongwith variant topo-morphology of sigmoid colon in the samecadaver.Case Report Sub-hepatic caecum with high riding vermiformappendix with absent ascending colon was seen on the rightside of abdominal cavity. Concomitantly on the left side of theabdominal cavity dilated, looped sigmoid colon occupied theleft hypochondrium, left lumbar region and left iliac fossa. Wereport these findings along with the embryological basis andclinical significance.Conclusion: An insight about the errors in development ofmid-gut resulting into the variant topography of caecum willfacilitate surgeons and radiologists in prompt diagnosis andquick modification of the protocol during invasive procedures.
