[Current Situation of Antibiotic Prophylaxis in Obesity and Metabolic Surgery - Data Analysis from the Study for Quality Assurance in Operative Treatment of Obesity in Germany]. / Aktueller Stand der Antibiotikaprophylaxe in der Adipositas- und metabolischen Chirurgie - Datenanalyse aus der Studie zur Qualitätskontrolle der operativen Therapie der Adipositas in Deutschland.

ABSTRACT

BACKGROUND: Since January 2005, the situation of metabolic and obesity surgery in Germany has been constantly evaluated by the German Bariatric Surgery Registry (GBSR). Data registration is performed using an internet online database with prospective data collection. All registered data were analysed in cooperation with the Institute of Quality Assurance at the Otto-von-Guericke University Magdeburg. METHODS: Data collection includes primary and revision/redo-procedures. A main focus of the current study is the analysis of data regarding the perioperative management, in particular, administration of antibiotics. RESULTS: Since 2005 a significant increase of primary bariatric procedures has been reported. For evaluation of the antibiotic regimen 12 296 primary operations including 684 balloons (BIB), 2950 gastric bandings (GB), 5115 Roux-en-Y-gastric bypasses (RYGBP), 120 Scopinaro's biliopancreatic diversions (BPD), 164 duodenal switches (DS), 3125 sleeve gastrectomies (SG) and 138 other procedures were analysed. In total 77.3 % of the patients with primary procedures received perioperative antibiotics. Patients without concomitant comorbidities received antibiotics significantly less often compared to those with comorbidities. Wound infection rates were comparable for patients who underwent either gastric banding or sleeve gastrectomy. CONCLUSION: Surgery has been accepted step by step as a treatment for morbid obesity and its comorbidities in Germany during the last few years. There is only little experience in the literature regarding antibiotic therapy as well as prophylaxis in bariatric surgery. Based on the results of the current study we recommend rather the selective than the routine use of antibiotics depending on different parameters, e.g., operative time, preoperative BMI and concomitant comorbidities.
