BAROS: An effective system to evaluate the results of patients after bariatric surgery

Background: Success in bariatric surgery is most. often evaluated by a sufficient loss of excess weight and an improvement in the medical conditions. The expected increase in quality of life (QoL) after weight loss, however, has not often been systematically analyzed. BAROS (Bariatric Analysis and Reporting Outcome System) is a scoring system which, along with easy handling, allows comparisons to be made internationally. Methods: 386 morbidly obese patients who had undergone bariatric surgery in our hospital were evaluated with BAROS. Five categories-failure, fair, good, very good, excellent-were taken from the scoring system that BAROS offers. This system has three major points: excess weight loss, medical co-morbidities and QoL. Points are subtracted for reoperations and defined complications. The operations performed were silastic ring vertical gastroplasty (72%), adjustable gastric banding (23%), biliopancreatic diversion (3%), vertical banded gastroplasty (1%) and gastric banding of Molina (1%). Results: In 1991 and 1993, we had a fair result in 3% and 10% of the patients. A good score with a mean of 3.6 to 4.1 was reached in 1992, 1994 and 1995. In the last 3 years, 1996 to 1998, the mean score was 5.0 to 5.7, which is a very good result when compared with the scoring key. Conclusion: BAROS is a valuable tool to access the QoL of patients who have undergone bariatric surgery.
