Background: Despite advances in endoscopic treatment, many colonic adenomas are still referred for surgical resection. There is a paucity of data on the suitability of these lesions for endoscopic treatment.
Objective: To analyze the results of routine repeat colonoscopy in patients referred for surgical resection of colon polyps without biopsy-proven cancer.
Design: Retrospective review.
Setting: University hospital.
Patients: Patients referred to a colorectal surgeon for surgical resection of a polyp without biopsy-proven cancer.
Interventions: Repeat colonoscopy.
Main outcome measurements: The rate of successful endoscopic treatment.
Results: There were 38 lesions in 36 patients; 71% of the lesions were noncancerous and were successfully treated endoscopically. In 26% of the lesions, previous removal was attempted by the referring physician but was unsuccessful. The adenoma recurrence rate was 50%, but all recurrences were treated endoscopically and none were cancerous. Two patients were admitted for overnight observation. There were no major adverse events.
Limitations: Single center, retrospective.
Conclusions: In the absence of biopsy-proven invasive cancer, it is appropriate to reevaluate patients referred for surgical resection by repeat colonoscopy at an expert center.
