Review article: indication and type of surgery in Crohn's disease.

The large majority of patients affected by Crohn's disease require surgery during their clinical history. Radical resection originally advocated for Crohn's disease does not decrease the recurrence rate, and repeated resections predispose patients to the development of short-bowel syndrome. Over the last few years, conservative surgery has become accepted by many authors as a safe means of treating obstructive Crohn's disease. In this review article we analyse the efficacy and safety of conservative techniques, in comparison with resective surgery. Indications, advantages and technical aspects of resective and conservative surgery are reported. The experience with 489 patients treated for complicated or treatment refractory Crohn's disease in our Institution suggests that strictureplasty is a safe and effective procedure in many cases, as reported by other authors. The risk of cancer in areas of active disease as in stenosis treated with strictureplasty seems to be negligible. Resective surgery still represents the 'gold standard' in patients with perforating Crohn's disease; however, conservative surgery, usually contraindicated in perforating Crohn's disease, can be advocated in patients with localized perforating disease presenting an actual risk of short bowel syndrome.
