1 TITLE: Change in Disease Status Following Bariatric Surgery: Clinical Evidence DATE: 09 June 2010 RESEARCH QUESTION: What is the clinical evidence that bariatric surgery can improve the disease status of patients with endocrinological diseases? METHODS: A focused search (bariatric surgery concepts appeared in title or as a major subject heading) was conducted on key health technology assessment resources, including PubMed, the Cochrane Library (Issue 5, 2010), University of York Centre for Reviews and Dissemination (CRD) databases, ECRI (Health Devices Gold), EuroScan, international health technology agencies, and a focused Internet search. The search was limited to human, English language articles published between January 1, 2005 and June 6, Filters were applied to limit the retrieval to health technology assessments, systematic reviews, meta-analyses, randomized controlled trials, controlled clinical trials, and observational studies. Internet links were provided, where available. RESULTS: HTIS reports are organized so that the higher quality evidence is presented first. Therefore, health technology assessment reports, systematic reviews, and meta-analyses are presented first. These are followed by randomized controlled trials and non-randomized studies. Due to the large volume of relevant literature, inclusion was limited to studies in which endocrinological disease status was considered as an outcome, or if the authors were presenting long-term outcomes of bariatric surgery. Only studies published from 2008 to present were included. One health technology assessment, three systematic reviews, one randomized controlled trial, and 21 non-randomized studies were included. Additional articles of potential interest can be found in the appendix. Disclaimer: The Health Technology Inquiry Service (HTIS) is an information service for those involved in planning and providing health care in Canada. HTIS responses are based on a limited literature search and are not comprehensive, systematic reviews. The intent is to provide a list of sources of the best evidence on the topic that CADTH could identify using all reasonable efforts within the time allowed. HTIS responses should be considered along with other types of information and health care considerations. The information included in this response is not intended to replace professional medical advice, nor should it be construed as a recommendation for or against the use of a particular health technology. Readers are also cautioned that a lack of good quality evidence does not necessarily mean a lack of effectiveness particularly in the case of new and emerging health technologies, for which little information can be found, but which may in future prove to be effective.
