Undetected and undiagnosed comorbidity in patients with obesity undergoing bariatric surgery-Results from the Berlin Bariatric Cohort study.

The quality of general obesity management before bariatric surgery (BS) is rarely investigated. Inadequate information regarding undetected and undiagnosed comorbidities (UUCs) in individuals with obesity may influence the penetration, risks, and outcomes of BS. We conducted a cohort study involving a pre-specified medical check-up in a cooperation between a BS department and an outpatient medical centre.

Evidence-based German guidelines for surgery for obesity.

Background: The young field of obesity surgery (bariatric surgery) in Germany expands as a consequence of the rapid increase of overweight and obesity. New surgical methods, minimal access techniques, and the enormous increase of scientific studies and evidence, all contribute to the success of bariatric surgery, which is the only realistic chance of permanent weight loss and regression of secondary diseases in many cases.

Methods: A systematic literature review, classification of evidence, graded recommendations, and interdisciplinary consensus.

Status of bariatric surgery in Germany--results of the nationwide survey on bariatric surgery 2005-2007.

Background: Most studies on bariatric surgery outcomes are performed as clinical trials or reflect the clinical experience in single centers. The status of bariatric surgery in Germany has been examined with the cooperation of clinics and hospitals at the Institute of Quality Assurance in Surgery at the Ottovon-Guericke University of Magdeburg (Germany) since January 1, 2005.

Methods: In this prospective multicenter observational study, the data obtained for all primary bariatric procedures, including all repeated operations, performed on consecutive patients with morbid obesity at participating hospitals from 2005 to 2007 were prospectively collected using an internet online data registry.
