The patient was turned and scope was changed for colonoscopy.  Prior to colonoscopy, it was noted that there was a perianal fistula at 7 o'clock.  The colonoscope was then inserted into the anal verge.  The colonic clean out was excellent.  The scope was advanced without difficulty to the cecum.  The cecal area had multiple ulcers with exudate.  The ileocecal valve was markedly distorted.  Biopsies were obtained x2 in the cecal area and then the scope was withdrawn through the ascending, transverse, descending, sigmoid, and rectum.  The colonic mucosa in these areas was well seen and there were a few scattered aphthous ulcers in the ascending and descending colon.  Biopsies were obtained in the cecum at 65 cm, transverse colon 50 cm, rectosigmoid 20 cm, and rectum at 5 cm.  No fistulas were noted in the colon.  Excess air was evacuated from the colon.  The scope was removed.  The patient tolerated the procedure well and was taken to recovery in satisfactory condition.
