"The purpose is to provide up-to-date information on the basics of colorectal surgery, covering a broad variety of topics. ... The audience seems to be practitioners who may encounter proctology in the office setting and those already with a knowledge base in colorectal or general surgery ... . this is a terrific reference. ...
