Abstract
Background Roux-en-Y gastric bypass (RYGBP) is usually considered as the procedure of choice for morbid obesity, but its use has been limited in Europe. It is not known whether results with European patients match those from the USA. Methods A total of 466 patients were followed prospectively regarding weight loss, co-morbidities, quality of life and morbidity after primary laparoscopic RYGBP. Overall assessment was done using the bariatric analysis and reporting outcome system (BAROS). Results Conversion to open surgery was necessary in three patients. The overall early morbidity rate was 17·0 per cent and the rate of major complications was 4·7 per cent. The mortality rate was 0·2 per cent. Major morbidity decreased over time. Excess weight loss of over 50 per cent was maintained for up to 4 years in 71·4 per cent of the morbidly obese and 65·2 per cent of the superobese patients. Co-morbidities resolved or improved in most patients and quality of life improved. At 3 years, the BAROS score was excellent or very good in 77·1 per cent and good in 22·8 per cent. Late complications leading to reoperation developed in 19 patients (4·1 per cent). Conclusion These results are satisfactory and comparable to those reported from the USA. Owing to limitations associated with purely restrictive bariatric procedures, laparoscopic RYGBP is likely to become the procedure of choice for treatment of morbid obesity in Europe.
