INTRODUCTION: Anastomotic surgical recurrence after bowel resection is a major problem in patients with Crohn's disease. The aim of this prospective observational study was to evaluate the efficacy of a novel technique for restoring bowel continuity after resection involving either the small or the large intestine. METHODS: The first case was instructed by Dr. Kono at Fujita Health University. The involved bowel segment was divided transversely with a linear stapler. The edges of two stapled lines are then connected to create a supporting column, which prevented surgical recurrence from anastomotic distortion due to mesenteric longitudinal ulcers. Thereafter, an antimesenteric longitudinal enterotomy was performed on each side to create a large-sized handsewn end-to-end anastomosis. RESULTS: Thirty consecutive patients underwent Kono-S anastomoses from December 2009 to August 2013. Neither anastomotic leakage nor surgical recurrence was observed during a median follow-up period of 35 months. Endoscopic surveillance was performed in 18 cases (69.2%) undergoing ileo-colonic or ileo-rectal anastomosis with an average Rutgeert's score of 0.78 (0-3) at a mean of 14.5 months postoperatively. CONCLUSION: The Kono-S anastomosis for Crohn's disease has been a safe and feasible technique. Long-term outcomes are required to confirm its advantage in preventing surgical recurrence at the anastomosis.
