Summary
In this procedure, the provider examines the inner part of the anus, rectum, and the sigmoid colon using a proctosigmoidoscope, a short rigid instrument with a camera at its one end. He then decompresses the volvulus, an abnormal twisting of the loop of the intestine, which causes a bowel obstruction.
