A new model of strictureplasty for multiple and long stenoses in Crohn's ileitis: side-to-side diseased to disease-free anastomosis.

Conservative surgery has become the treatment of choice for diffuse jejunoileal Crohn's Disease. Previous research described a conservative approach both for multiple strictures located in close proximity to each other and for long stenoses. The side-to-side enteroenteric anastomosis has gained popularity and has lead to nonresectional surgery even for those patients who, until now, were considered suitable only for resection. This technique however, presents in our hands some disadvantages represented mainly by early restenosis at the two edges of the strictureplasty, probably caused by the sutures between the diseased and the thickened part of the bowel. We propose a new technique called "side-to-side diseased to disease-free anastomosis," which consists of dividing the bowel and the mesentery at the beginning of the stenoses and suturing the disease-free bowel above the stenoses to the diseased bowel. This procedure could avoid early restenosis at the two ends of the strictureplasty. Moreover, it is faster and safer to perform because the knots of the sutures are tied to the normal bowel with less risk of bleeding.
