  After proper informed consent was obtained, the patient was brought to the Endoscopy Suite.  She was placed in the left lateral position and was given sedation by the Anesthesia Department.  A digital rectal exam was performed and there was no evidence of mass.  The colonoscope was then inserted into the rectum.  There was some solid stool encountered.  The scope was maneuvered around this.  There was relatively poor prep as the scope was advanced through the sigmoid colon and portions of the descending colon.  The scope was then passed through the transverse colon and ascending colon to the cecum.  No masses or polyps were noted.  Visualization of the portions of the colon was however somewhat limited.  There were scattered diverticuli noted in the sigmoid.
