Progress in the application of transrectal ultrasound in preoperative evaluation of anal preservation in low and middle rectal cancer surgery / 中国医师杂志

ABSTRACT

Rectal cancer is one of the most common malignant tumors in the digestive system, and mid to low rectal cancer has attracted great attention due to its unique anatomy, examination, and treatment. Accurate diagnosis and appropriate treatment are key to improving the prognosis of rectal cancer patients. One of the long-standing technical challenges in colorectal surgery is how to make a more accurate evaluation of the surgical plan for rectal cancer before surgery. Transrectal intracavitary ultrasound can provide some effective objective basis for the selection of surgical plans for middle and low rectal cancer. This article reviews the application value and progress of preoperative evaluation of preoperative staging and anal preservation of middle and low rectal cancer using transrectal intracavitary ultrasound.
