Strategies to evaluate synchronous carcinomas of the colon and rectum in patients that present for emergent surgery.

Abstract

It is not always possible to evaluate patients that present acutely with carcinoma of the colon and rectum for synchronous lesions. Patients that require emergent surgery necessitate urgent and efficient operation. Patients with lower gastrointestinal bleeding, perforation, or obstruction represent a challenging subset of patients with colorectal cancer. An organized approach to these patients in the effort not to overlook a synchronous carcinoma is important. The present paper provides an evidenced-based approach to this special situation.
