Bariatric analysis and reporting outcome system (baros) following biliopancreatic diversion

Background: The Bariatric Analysis and Reporting Outcome System (BAROS) has been recently introduced to assess the modifications of weight, comorbidities and quality of life (QOL) after bariatric surgery, in order to achieve a standard for comparison in the treatment of obesity. This study reports the Authors' experience, analyzing with BAROS a consecutive series of morbidly obese patients. Methods: From November 1998 to February 2001, 30 patients with morbid obesity underwent biliopancreatic diversion (BPD) in our Department. Patients were followed-up after 1, 3, 6, 9, 12 months and than yearly. Modifications of the Body Mass Index (BMI), percentage of the initial excess weight loss (IEW%L), comorbidities and type and incidence of complications were measured. The course and QOL were assessed using BAROS after a minimum follow-up of 18 months, or in absence of IEW%L modification at two consecutive scheduled visits. Results: According to the BAROS, the outcome was classified as Excellent in 10% of cases, Very Good in 63.3%, Good in 20%, Fair in 6.7%; no patients had Failure course. Ninety-three percent of patients had resolution of at least one of their major comorbidities, and an improvement of the medical conditions was registered in all the cases. The QOL was greatly improved in 55%, improved in 35% and did not change in 10% of the patients. Conclusion: BPD provides effective weight loss, improvement or resolution of major co-morbidities and increases the QOL of morbidly obese patients. BAROS is an useful tool to assess the outcome after bariatric surgery.
