Modified subcutaneous suction drainage to prevent incisional surgical site infections after radical colorectal surgery

摘要

Background: Many studies have been performed to evaluate the effect of subcutaneous suction drainage to prevent incisional surgical site infections (SSIs) after radical colorectal surgery. However, the result has been controversial. The main reason may be that subcutaneous suction drainage is more prone to develop blockages, and the drainage tubes themselves serve as a conduit for bacteria into the wound. Therefore, we modified this method and evaluated this new method (subcutaneous suction drainage and intermittent irrigation) in patients who underwent radical colorectal surgery.
