Evaluation of health status and quality of life after bariatric surgery: comparison of standard Roux-en-Y gastric bypass, vertical banded gastroplasty and laparoscopic adjustable silicone gastric banding.

Author information

AO. Krankenhaus Hallein, Austria.



This study is a trial to compare the effects and outcomes of three different bariatric procedures performed in two centers. Standard Roux-en-Y gastric bypass was performed by Dr. Norman Samuels in Fort Lauderdale (Florida); vertical banded gastroplasty and laparoscopic adjustable silicone gastric banding were done in Hallein (Salzburg) by Dr. Emanuel Hell and Dr. Karl Miller.


In a prospective comparative study 30 matched patients from each group were followed to assess post-operative improvement in health status and quality of life, to compare the three different techniques. The Bariatric Analysis and Reporting Outcome System (BAROS) as described by Oria and Moorehead has been used for evaluation.


The observation time was at least 3 years (3 to 8 years) in each individual case. A significant increase in quality of life and health status in 75% of the surgically-treated patients was observed when compared with a non-operated control group of morbidly obese patients.


By utilizing BAROS it has been found possible to compare the results of different procedures done by different surgeons with different techniques, utilizing patients from different cultures and with different languages. The results of this comparative study favor the standard gastric bypass for the treatment of morbid obesity. This operation is superior to purely gastric restrictive procedures in weight loss and improvement of quality of life.
