It is surrounded by peritoneum except posteriorly where the lateral cutaneous nerve of the thigh, usually, the fourth lumbar artery and sometimes, the ilioinguinal and iliohypogastric nerves cross behind it. Anteriorly, it is in relation with the convolutions of the ileum, the right edge of the greater omentum and the abdominal wall. ^’ The right colic flexure; It comprises the terminal part of the ascending colon and the commencement of the transverse colon, which turns downwards, forwards and to the left. ’ |
