With the almost universal adoption of "left colectomy" rather than segmental resections of carcinomas of the sigmoid and left colon there is still some discrepancy in the type of operation advocated. Diversity of techniques of the component parts of a "left colectomy" results in disagreement as to what constitutes an adequate resection and leads to difficulties in the evaluation of the results of surgical treatment. As compared with resections of the right colon, there is no standardized left colectomy.
An adequate and satisfactory resection for carcinoma of the colon should have for its purpose (1) the wide removal of the primary lesion in continuity with appropriate tissue pathways (venous and lymphatic) of potential secondary spread compatible with minimal morbidity and mortality; (2) the prevention of spread occurring as embolization or "seeding" during operation; (3) the recognition and removal of precursors of potential new growths, and (4) the salvage of as
