explained to the patient, who indicated her understanding and signed the corresponding consent forms. the efficiency of a colonoscopy in detecting lesions was discussed with the patient and it was

the left lateral decubitus position and the colonoscope was introduced through the rectum and advanced under direct visualization until the cecum was reached. careful visualization of the colon was performed as the colonoscope was withdrawn. the colonoscope was retroflexed within the rectum. the procedure was not difficult. the quality of the preparation was good. the patient tolerated the procedure well. there were no complications. findings: contents: large amount of red blood and clots were seen in the rectum, sigmoid colon, descending colon and transverse colon. excavated lesions multiple diverticula were seen in the whole colon. diverticulosis appeared to be severe. other source of bleeding could not be identified, but most likely appears to be left sided diverticulosis. impression: blood in the rectum, sigmoid colon, descending colon and transverse colon diverticulosis of the whole colon source of bleeding could not be identified, but most likely appears to be left sided diverticulosis. recommendations: transfer to icu ir consult for angiogram today check hct and transfuse as needed. discussed with dr. brief hospital course: the patient is a 57 year old woman
