ABSTRACT During the past decade, the field of bariatric surgery has changed dramatically. This study was intended to determine trends in the use of bariatric surgery in the United States. Data used were from the Nationwide Inpatient Sample from 2003 through 2008.
We used ICD-9 diagnosis and procedural codes to identify all hospitalizations during which a bariatric procedure was performed for the treatment of morbid obesity between 2003 and 2008. Data were reviewed for patient characteristics, annual number of bariatric procedures, and proportion of laparoscopic cases. US Census data were used to calculate the population-based annual rate of bariatric surgery per 100,000 adults. The number of surgeons performing bariatric surgery was estimated by the number of members in the American Society for Metabolic and Bariatric Surgery.
For the period between 2003 and 2008, the number of bariatric operations peaked in 2004 at 135,985 cases and plateaued at 124,838 cases in 2008. The annual rate of bariatric operations peaked at 63.9 procedures per 100,000 adults in 2004 and decreased to 54.2 procedures in 2008. The proportion of laparoscopic bariatric operations increased from 20.1% in 2003 to 90.2% in 2008. The number of bariatric surgeons with membership in the American Society for Metabolic and Bariatric Surgery increased from 931 to 1,819 during the 6 years studied. The in-hospital mortality rate decreased from 0.21% in 2003 to 0.10% in 2008.
In the United States, the number of bariatric operations peaked in 2004 and plateaued thereafter. Use of the laparoscopic approach to bariatric surgery has increased to >90% of bariatric operations. In-hospital mortality continually decreased throughout the 6-year period.

    • "In particular, it is not clear how bariatric surgery in one family member affects healthy lifestyle behavior modifications among the patient and family members in the patient's social network who have not had surgery. With the prevalence of bariatric surgery prominent [19], evaluating the effects of surgery on family members is of importance. The aim of the present study was to review and describe the state of the literature in terms of family-based approaches to improving metabolic outcomes in bariatric surgery patients and their families.

    ABSTRACT: Background Bariatric surgery must be partnered with post-operative lifestyle modifications for enduring weight loss and related health effects to be fully appreciated. Little is known about how these lifestyle modifications may be affected by the involvement of other family members living in the household; therefore, this review describes current family-based approaches to improving post-operative outcomes in bariatric surgery patients and their families. Methods A MEDLINE search of publications between 1999-to-2014 was conducted in January 2014. Retrieved titles and abstracts were assessed by two authors to determine relevance to the topic surrounding family-based approaches to improve post-bariatric surgery outcomes. All study designs except case studies were considered if they included some aspect of family as a predictor in relation to improved health outcomes after surgery. Results Initial searches yielded 650 publications (bariatric surgery + family n=193; bariatric surgery + child n=338; bariatric surgery + spouse n=4; bariatric surgery + social support n=115). Two studies met criteria for a family-based approach to improving metabolic outcomes in bariatric patients. Seven studies discussed the impact of bariatric surgery on families. All other studies were excluded for not discussing family-based approaches. Conclusions Despite limited documentation of family-based approaches on improving health outcomes in patients who underwent bariatric surgery, evidence suggests that such an approach may be advantageous if planned a priori to occur before, during, and after bariatric surgery. Future studies could test the combination of bariatric surgery and a family-based approach for improved metabolic outcomes in both the patient and involved family member(s).

    ABSTRACT: Zusammenfassung Adipositas wird mittlerweile als eigenständige Krankheit anerkannt. Die World Health Organization (WHO) spricht von einer weltweiten Epidemie. Folgeerkrankungen betreffen alle Organsysteme. Bariatrische Operationen führen bereits frühzeitig nach der Durchführung zu einer Verbesserung oder gar Remission der adipositasassoziierten Komorbiditäten. Bei bariatrischen Operationen wird zwischen restriktiven, das Magenvolumen verkleinernden Verfahren, malabsorptiven und gemischten Verfahren differenziert. Die präoperative anästhesiologische Evaluation der Begleiterkrankungen erfolgt mit besonderem Augenmerk auf bestehende Herz- und Lungenfunktionseinschränkungen (z. B. Kardiomyopathien, obstruktive Ventilationsstörungen). Bei extrem adipösen Patienten besteht erhöhte Aspirationsgefahr. Die Narkoseeinleitung kann konventionell, bei zusätzlichen Risikofaktoren fiberoptisch oder als „rapid sequence induction“ erfolgen. Die Pharmakokinetik aller eingesetzten Substanzen ist im Vergleich zum normalgewichtigen Patienten stark verändert. Postoperative Thromboembolien stellen das höchste Letalitätsrisiko dar; deshalb muss eine suffiziente medikamentöse und nichtmedikamentöse Thromboseprophylaxe erfolgen.

    ABSTRACT: Bariatric surgery is increasing at an enormous rate in all countries but the indications for the operation on the basis of metabolic derangements are not clear, as only one controlled randomized trial specifically for a comorbidity has been performed. Thus, it is not clear if bariatric surgery should be offered to all obese patients with long standing type 2 diabetes or poorly controlled hypertension or hypertriglyceridemia, even though these conditions clearly respond in most patients to bariatric surgery and weight loss. It would appear that patients with early type 2 diabetes with reasonable control and a greater body mass index gain more benefit from the operation. More randomized trials are required.
