Purpose:
Prospective evaluation of colon double-contrast enemas in patients with incomplete colonoscopy during routine examination.
Materials And Methods:
From 1. February 1993 through 31. January 1994 we prospectively evaluated all patients undergoing a double-contrast barium enema following incomplete colonoscopy in the endoscopy unit of the Department of Surgery of the University Hospital Marburg. The examination was carried out using the typical double-contrast technique at least 24 h after colonoscopy. The results of the barium enema were correlated with the findings at colonoscopy with regard to completion of the diagnostic procedure and additional pathological findings.
Results:
Of 448 colonoscopies 168 remained incomplete. Sixty patients underwent an additional double-contrast study of the colon. In 43 patients this study was sufficient to complete the diagnostic procedure. Unknown pathological diagnoses were found in 11 patients. In 2 patients an adenocarcinoma and in 9 patients polypoid lesions were detected.
Conclusion:
After incomplete colonoscopy a double-contrast barium enema should be performed to complete the diagnostic examination of the whole colon and to reveal unknown additional pathological findings.
