Colorectal surgery for functional bowel disorders.

Surgery is a last-resort treatment for the management of severe constipation, an alternative after failure of medical treatment. We can distinguish two types of management: "conservative" colon-sparing surgery, i.e. the Malone procedure (MP), or sacral neuromodulation (SNM), and "radical" surgery such as colorectal resection. While the place of SNM remains to be defined, the MP is well codified and has shown very satisfactory results. For radical treatment, total colectomy with ileo-rectal anastomosis is the reference procedure because it is the best documented. The place of more limited segmental colectomies is poorly defined and needs a more precise identification of the colonic segment involved. Finally, it is imperative that any severe constipation be managed within a multidisciplinary radiology-medico-surgical consultative program. Indeed, a multidisciplinary strategy allows rigorous selection of patients, the only guarantee of better long-term functional results, even though they unfortunately remain uncertain.
