ABSTRACT
BACKGROUND AND STUDY AIM:
Although colonoscopy is reliable in identifying colorectal cancer (CRC), studies have demonstrated incorrect tumour localization in 21-34% of colonoscopies when compared with surgical localization. The aim of this study was to determine our accuracy in determining the position of CRCs detected at colonoscopy with the aid of the ScopeGuide endoscope positioning device. PATIENTS ANDMETHODS:
Cancers identified within the English National Bowel Cancer Screening Programme were studied. Retrospective analysis was undertaken of all patients diagnosed with CRC during the first screening round in Wolverhampton Bowel Cancer Screening Centre, England. ScopeGuide was used in all cases. Data from colonoscopy reports, computed tomography reports and surgical resection specimens were analysed.RESULTS:
A total of 82 cancers were identified within the surgical resection specimen in 80 patients. Two proximal cancers were not identified at colonoscopy due to obstruction by the distal cancers. Colonoscopy with the aid of the endoscopy positioning device correctly identified the tumour location in 93.75% of cases in which the tumour could be reached endoscopically. Abdominopelvic computed tomography localized 82.5% of CRC.CONCLUSION:
The ScopeGuide endoscopy positioning device enables accurate localization of cancers at colonoscopy. Tattooing of suspected cancer remains to be a best practice for localization during laparoscopic resection. The use of the endoscopic-positioning device may, however, result in greater confidence for localization of polypectomy sites, which have not been tattooed, in cases when cancer was not suspected but found histologically.
