Colon examination

This is performed by bimanual examination with one hand in the posterior abdominal wall and the other in the anterior abdominal wall for retroperitoneal colon such as ascending and descending colon in the left and right paracolic gutters. The transverse colon is fully intraperitoneal and can be palpated from the anterior abdominal wall together with the  sigmoid colon. They are first inspected, then palpated before percussion and finally auscultation.
