Kono-S anastomosis after intestinal resection for Crohn's disease.

Kono's anastomosis seems to be a safe procedure with encouraging results on the reduction of the need for reoperation due to relapse, but the few existing studies do not allow to draw final conclusions. Further comparative, randomized studies, with appropriate sample size, follow up and endoscopic evaluation are necessary to establish the real benefits in the use of this hand-sewn antimesenteric anastomosis compared to a stapled wide lumen side-to-side anastomosis.
