Abstract
Second-look surgery for recurrent colorectal carcinoma has been advocated for over four decades. Routine follow-up procedures gave way to clinically directed or carcinoembryonic (CEA)-directed procedures in the mid-1970's. In this paper, we review the results of second-look surgery for recurrent colorectal carcinoma and ask the question, "Is it worthwhile?" Excluding surgery for symptomatic patients, we conclude that second-look surgery should only be performed for recurrent colorectal carcinoma with the intent of rendering the patient disease-free. Without effective systemic therapy, "palliative" or "debulking" procedures probably do not increase survival. The most likely candidates for such a curative approach with second-look surgery are those with isolated liver, pulmonary, and, less frequently, regional recurrences.
