Rectal Villous Adenoma

  • Chad R. Launch

Villous adenomas are benign lesions that, if untreated, may progress to colon carcinoma. They tend to be sessile and may carpet a region of colon or rectum. Complete resection is necessary and may be accomplished endoscopically, surgically, or by endoscopic mucosal resection. This chapter uses a case of a distal rectal villous adenoma to explore alternatives in transanal management. A related topic, serial polypectomies, was discussed in Chapter 44, as applied to a sessile polyp of the cecum. In a way, these transanal excisions might be considered an example of natural orifice surgery, an area under active development at present.
