The sigmoid colon has an inverted V shaped mesentery by which it is attached to the posterior abdominal wall. The mesosigmoid begins at formation of the sigmoid colon. At its junction with the descending colon, the sigmoid colon becomes completely intraperitonealized with the formation of the mesosigmoid or sigmoid mesocolon.
