Abstract
OBJECTIVE: CT colonography (CTC) has been recognized as a complementary approach to evaluating the entire colon after incomplete colonoscopy (IC) in patients with occlusive colorectal cancer (CRC). The objective of this study is to evaluate changes in preoperative surgical planning after CTC is performed for patients with occlusive CRC and IC in an oncologic hospital. MATERIALS AND METHODS: This retrospective study included 65 consecutive patients with occlusive CRC who underwent CTC after IC at our institution from February 2000 to April 2016. CTC examinations and radiology reports were reviewed by an abdominal radiologist. Clinical information was obtained from a review of the electronic medical record. RESULTS: CTC contributed to a change in the initial surgical plan of the surgeon for 14 of 65 patients (21.5%). In these 14 patients, CTC detected five synchronous proximal colon polyps (35.7%), five synchronous proximal cancers (35.7%), two imprecise CRC locations (14.3%), one case of proximal colon ischemia (7.1%), and one instance of tumor infiltration of the urinary bladder (7.1%). All CTC findings were confirmed at surgery, and all proximal colon polyps were subsequently confirmed to be advanced adenomas. CONCLUSION: The preoperative CTC findings optimized the surgical management plan for 21.5% of patients with occlusive CRC and IC.
