Planes of sharp pelvic dissection for primary, locally advanced, or recurrent rectal cancer.
In the design of operations for rectal cancers, the focus is often on circumventing the local extent of disease and leaving the pelvis free of cancer. The local extent of disease may range from minimal intramural invasion to the direct extension of a primary tumor to pelvic sidewall structures, e.g., the internal iliac vessels. In the absence of distant spread, understanding the planes of pelvic anatomy may allow the knowledgeable surgeon to cure patients who would otherwise be declared unresectable. We present the four planes (and one rare situation) available for sharp dissection which allow for the resection of all but a few cases of locally advanced disease.
