The angiographic anatomy of the small arteries and their collaterals in colorectal resections: some insights into anastomotic perfusion.

Objective: The aim of this study was to examine by screening angiography the anatomy of the small arteries and their collaterals in colorectal resections in order to identify factors that might be implicated in anastomotic leak.

Summary Background Data: Anastomotic leak is more frequent following low anterior resection. Vascular compromise is frequently implicated but poorly understood as a mechanism.

Metastatic prostate cancer masquerading clinically and radiologically as a primary caecal carcinoma.

Background: Prostatic carcinoma is the second most common cause of cancer-related deaths in males in the West. Approximately 20% of patients present with metastatic disease. We describe the case of a patient with metastatic prostate cancer to the bowel presenting clinically and radiologically as a primary caecal cancer.
