Postoperative venous thromboembolism in Asia: a critical appraisal of its incidence.

Objectives: Venous thromboembolism (VTE) has historically been perceived to be a rare disorder in Asia. However, new evidence has emerged recently that contradicts this perception. The question of routine VTE prophylaxis has been hotly debated in Asia due to disagreement on its incidence.

Pharmacotherapy for chronic hemorrhagic radiation proctitis.

Endoscopic thermal therapy and formalin are being increasingly recommended for the treatment of chronic hemorrhagic radiation proctitis. It may be too early, however, to discard pharmacologic agents from the management process, especially in medical institutions where specialized equipment is unavailable. We prospectively assessed the effectiveness of medical therapy in 14 consecutive patients with chronic hemorrhagic radiation proctitis from July 1999 to June 2001.

Antibiotic prophylaxis in elective colorectal surgery.

The tendency for surgeons to prolong the administration of prophylactic antibiotic therapy in the postoperative period is a well-known fact. The aim of this study was to elucidate the pattern of prophylactic antibiotic utilization in elective colorectal surgery and to determine if evidence-based medicine is employed in relation to this practice.
