This study proposes a randomized prospective study comparing the Kono-S anastomosis to the standard side-to-side anastomosis.This will be a multi-center randomized prospective trial. Patients with Crohn's ileitis or Crohn's ileocolitis requiring resection will be randomized to undergo either the Kono-S anastomosis or the side-to-side functional end anastomosis.Read full original descriptionShow less
Prospective Randomized Study of the Kono-S Anastomosis Versus the Side-to-side Functional End Anastomosis in the Prevention of Post-operative Recurrence of Crohn's Disease
This study proposes a randomized prospective study comparing the Kono-S anastomosis to the standard side-to-side anastomosis.This will be a multi-center randomized prospective trial. Patients with Crohn's ileitis or Crohn's ileocolitis requiring resection will be randomized to undergo either the Kono-S anastomosis or the side-to-side functional end anastomosis.
Inclusion: Patients with Crohn's ileitis or ileocolitis requiring initial surgical resection; Age of 18 years and older, male and female; All Phenotypes of Crohn's diisease will be included: nonpenetrating (B1), stricturing (B2), and penetrating (fistulating) (B3), according to the Vienna classification; The patients can be on any medications coming into surgery, including prior anti- tumor necrosis factor(TNF) therapy.
Exclusion: Patients that need change of surgical procedure as per the surgeon at the time of the intraoperative abdominal evaluation; Patients with more than one non-contiguous site of active disease, thus requiring multiple resections or additional bowel sparing procedures at the time of surgery; Patients with Crohn's disease extending to the cecum and ascending colon; Patients under 18 years of age; Patients with recurrent Crohn's; Pregnant patients; Patients who will need preventive postoperative medical treatment.
