T1  - Einfluss der präoperativen Konditionierung mittels Magenballon vor bariatrischer Operation auf den Therapieerfolg bei extremer Adipositas –  Eine retrospektive Vergleichsstudie
T1  - Impact of preoperative weight loss achieved by gastric balloon on peri‑ and postoperative outcomes of bariatric surgery in super‑obese patients - a retrospective matched‑pair analysis
N2  - Die Adipositaschirurgie ist die effektivste Methode in der Behandlung der Adipositas. Bei extrem adipösen Patientin ist eine primäre Operation oftmals riskant. Die Anlage eines Magenballons als erster Schritt von Mehrstufenkonzepten kann die Operabilität gewährleisten und die perioperative Sicherheit erhöhen. Durch den Magenballon wird ein signifikanter Gewichtsverlust erreicht. Der postoperative Gewichtsverlust fällt allerdings schwächer aus. Es ist wichtig, den Patienten realistische Therapieergebnisse zu vermitteln, um überhöhte Erwartungen und Unzufriedenheit zu vermeiden. Die Sleevegastrektomie eignet sich besonders für extrem adipöse Patienten, da diese eine geringere Komplikationsrate aufweist und einfach in einen Roux-en-Y Bypass umzuwandeln ist.
N2  - Bariatric surgery is currently the most effective method in the treatment of obesity. In extreme obese patients, primary surgery is often challenging and risky. A treatment with gastric balloon as first of more-stage concepts can make surgery possible and increase the perioperative safety. As a result of the gastric balloon a significant weight loss can be achieved. However, postoperative weight loss is reduced. It is important to convey patients realistic results in order to avoid excessive expectations and dissatification. Laparoscopic sleeve gastrectomy is favourable for extrem obese patient because of its lower complication rate and good technical feasibility of conversion to roux-en-y gastric bypass.

T1  - Impact of preoperative weight loss achieved by gastric balloon on peri- and postoperative outcomes of bariatric surgery in super-obese patients: a retrospective matched-pair analysis
JF  - Langenbeck’s Archives of Surgery
N2  - Background
An intragastric balloon is used to cause weight loss in super-obese patients (BMI > 60 kg/m\(^2\)) prior to bariatric surgery. Whether weight loss from intragastric balloon influences that from bariatric surgery is poorly studied.

Methods
In this retrospective, single-center study, the effects of intragastric balloon in 26 patients (BMI 69.26 ± 6.81) on weight loss after bariatric surgery (primary endpoint), postoperative complications within 30 days, hospital readmission, operation time, and MTL30 (secondary endpoints) were evaluated. Fifty-two matched-pair patients without intragastric balloon prior to bariatric surgery were used as controls.

Results
Intragastric balloon resulted in a weight loss of 17.3 ± 14.1 kg (BMI 5.75 ± 4.66 kg/m\(^2\)) with a nadir after 5 months. Surgical and postoperative outcomes including complications were comparable between both groups. Total weight loss was similar in both groups (29.0% vs. 32.2%, p = 0.362). Direct postoperative weight loss was more pronounced in the control group compared to the gastric balloon group (29.16 ± 7.53% vs 23.78 ± 9.89% after 1 year, p < 0.05 and 32.13 ± 10.5% vs 22.21 ± 10.9% after 2 years, p < 0.05), who experienced an earlier nadir and started to regain weight during the follow-up.

Conclusion
A multi-stage therapeutic approach with gastric balloon prior to bariatric surgery in super-obese patients may be effective to facilitate safe surgery. However, with the gastric balloon, pre-treated patients experienced an attenuated postoperative weight loss with an earlier nadir and earlier body weight regain. This should be considered when choosing the appropriate therapeutic regime and managing patients’ expectations.
