BACKGROUND: @entity1 with @entity5845 are prone to weight-related disease, reduced quality of life and shortened life expectancy. Long-term weight loss is unsatisfactory with conservative treatment and weight-reducing surgery is increasingly performed in all Norwegian health regions. METHODS: This review is based on electronic database searches. We describe the two procedures most commonly performed in Norway, i.e. gastric bypass and biliopancreatic diversion with duodenal switch, including preoperative workup and expected results after surgery. The domestic use of different surgical techniques is also outlined. RESULTS: In Norway, around 750 bariatric procedures were planned in 2006. Gastric bypass yields a weight reduction of 30% two years after the operative. Resolution of type 2- @entity6 , @entity101 , @entity407 , @entity27 has been demonstrated in most @entity1 . A majority of @entity1 report improved quality of life. Procedure-related mortality is less than 1% and surgical complications occur in approximately 20%. @entity3147 are frequent. Weight loss is somewhat greater after biliopancreatic diversion with duodenal switch, but the procedure is more complex. Life-long follow-up is recommended after bariatric surgery. INTERPRETATION: In selected @entity1 with @entity5845 , bariatric surgery is a viable treatment. However, prospective long- term studies are needed.
