Potential long-term treatment for type 2 diabetes

According to this article at The Guardian, the Dutch have done a trial with 50 subjects with type 2 diabetes underwent an hour-long procedure that involved destroying the mucus membranes of the small intestine (probably not the whole small intestine, most likely the jejunum). In 2 weeks the body replaces the missing mucus membrane. After 1 year, 90% of patients still have stable blood sugar levels. It’s unknown yet if this can be a permanent treatment, or if the procedure needs to be repeated regularly.
