A name given to the duplicatures of the peritoneum, which fix the different parts of the colon to the abdominal parietes. It has received different names, according to its situation. The right lumbar mesocolon fixes the ascending colon to the corresponding lumbar region. The transverse mesocolon arises from the concave arch of the colon, and forms a septum between the epigastric and umbilical regions. Its inferior portion is continuous with the mesentery. The left lumbar mesocolon, which contains the ascending colon, is continuous below with the Iliac mesocolon. The last includes between its layers the sigmoid flexure of the colon, and ends in the mesocrectum. Under the right kidney, it is narrow and firm, and forms the right ligament of the colon: at the under end of the left kidney, it forms the left ligament of the colon.
