Zusammenfassung

Die metabolische/bariatrische Chirurgie führt bei dem Großteil der Patienten mit morbider Adipositas zu einem nachhaltigen und klinisch relevanten Gewichtsverlust, zu einer Verbesserung der adipositasassoziierten Morbidität, der Lebensqualität und der Funktionalität. Mit der Reduktion von Risikofaktoren für kardiovaskuläre Ereignisse und Krebserkrankungen wird die Lebenserwartung verlängert. Aufgrund der sehr guten antidiabetischen Wirkung wird in der aktuell gültigen S3-Leitlinie eine metabolisch/bariatrische Operation bei schlecht einstellbarem Diabetes bereits ab einem Body-Mass-Index (BMI) von 30 kg/m2 empfohlen. Mit dem Edmonton-Staging-System kann eine vom BMI unabhängige mehrdimensionale Betrachtung des Schweregrades der Adipositas für den individuellen Patienten vorgenommen werden. Patienten mit relevanten adipositasassoziierten Begleiterkrankungen sollten priorisiert therapiert werden und das möglichst bevor Endorganschäden vorliegen, die zum einen das perioperative Risiko erhöhen und zum anderen – zumindest teilweise – nicht mehr reversibel sind. Der Definition individueller Therapieziele und der Vermittlung einer realistischen Erwartungshaltung sollten bereits präoperativ – aber auch im Verlauf – viel Aufmerksamkeit gewidmet werden. Eine unrealistische Erwartungshaltung – „Operation löst meine Probleme“, „Operation macht mich schöner“, „Operation beseitigt Stigma“, „Operation garantiert Therapieerfolg“ – ist nicht selten. Sie kann zu Frustrationen und psychischen Dekompensationen führen und muss möglichst früh durch das interdisziplinäre Team adressiert werden. Redundanzen und eine stringente im Team gleichgerichtete empathische Kommunikation verbessern die Therapieadhärenz, die Erwartungshaltung und so das Outcome.

Abstract

In the majority of patients with morbid obesity, metabolic/bariatric surgery leads to relevant and sustained weight loss and improves obesity-related comorbidities, quality of life and functionality. Moreover, the associated reduction of risk factors for cardiovascular events and cancerous diseases has been shown to improve life expectations. Due to its excellent antidiabetic effect, the currently valid national S3 guidelines now recommend metabolic/bariatric surgery in patients who have a body mass index (BMI) ≥30 kg/m2 with poorly controlled diabetes. The Edmonton staging system enables a multidimensional consideration of the severity grade of obesity for each individual patient independent of the BMI. Patients with relevant obesity-related metabolic comorbidities should be prioritized for treatment and if possible before the occurrence of end-organ damage that is at least in some cases irreversible and which also increases the perioperative risk. Therapeutic goals for each individual patient should be carefully defined preoperatively in order to mediate realistic expectations. Unrealistic expectations, such as “surgery solves my problems”, “surgery makes me more beautiful”, “surgery eliminates stigma”, and “surgery guarantees success”, are common in bariatric surgery patients. These unrealistic expectations can lead to frustration and to severe psychological decompensation and need to be addressed as early as possible by an interdisciplinary team. Redundancies, conclusive and empathic communication in the team improve therapy adherence, the expectations and therefore the overall outcome.
