(2) Kono\u2010S\u2009+\u2009close mesenteric resection. (3) Standard anastomosis + extended mesenteric resection. (4) Standard anastomosis + close mesenteric resection. The primary outcome is time to endoscopic recurrence of disease (up to 3\u2009years follow\u2010up). Secondary outcomes include rates of severe and symptomatic recurrence, complications, and quality of life scores. The locality of recurrence will be investigated using endoscopic assessment of the mucosa relative to mucosal tattoos placed at the time of operation. The degree and anastomotic locality of different immune cells will be compared before and after each intervention to better understand the mechanistic processes driving disease recurrence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study will robustly evaluate the efficacy of the Kono\u2010S anastomosis technique and extended mesenteric excision in reducing endoscopic recurrence rates.
