Late onset colono-gastric anastamotic strictures

Anastomotic strictures are the commonest late complication in colonic interposition, and has been reported in between 27% and 30% of patients over their lifetime so far. (183,184) The aetiology of these strictures includes cologastric reflux and food pooling in the colonic conduit. Both cause inflammation and then scarring of the anastomosis site, triggering the stricture. This is usually managed by endoscopic dilatation, but surgical resection is necessary in some patients.
