A Review of Current Research on Preoperative Bowel Preparation for Colorectal Cancer

Abstract

Colorectal cancer is one of the most common malignant tumors in China, and radical surgery is the first choice of treatment for colorectal cancer. With the development of the level of medical technology, colorectal cancer surgery has also undergone continuous improvement and has been widely used in clinical practice. However, surgical complications such as anastomotic leakage and postoperative infection are still the main problems of surgery, and there is still no thorough solution. Bowel preparation can clean the feces in the intestines and reduce the number of intestinal flora, which in turn reduces the incidence of postoperative complications. The current mainstream concept is that mechanical bowel preparation can effectively reduce the incidence of postoperative infection and anastomotic leakage, and is the preferred method of bowel preparation for colorectal surgery. There are many specific methods of preoperative bowel preparation, and since each method has its own advantages and disadvantages, there is still no recognized optimal solution, so it is necessary to choose the appropriate method according to the different conditions of individual patients.
