There is controversy about the usefulness of bursectomy and omentectomy during the surgical treatment of gastric cancer. Bursectomy, a procedure dissecting the peritoneal lining covering the pancreas and the anterior plane of the transverse mesocolon, is a major surgical aggression. There is no evidence that the procedure improves five years survival. It may be useful in serosal gastric cancer of the posterior wall. Excision or resection of all or part of an omentum does not have either an effect on survival. However, we recommend its use since its lack of benefit has not been completely ascertained.
