Owing to the LSG procedure, the stomach is functionally divided into a sleeve without propulsive peristalsis and an accelerated antrum. Accelerated emptying seems to be caused by faster peristaltic folds.

Introduction Clostridium difficile infection (CDI) is the most common cause of health-care-associated infectious diarrhea. Recurrence rates are as high as 20–30% after standard treatment with metronidazole or vancomycin, and appear to be reduced for patients treated with fidaxomicin. According to the literature, the risk of CDI recurrence increases after the second relapse to 30–65%. Accurate data for Germany are not yet available.MethodsBased on the research database of arvato health analytics (Munich, Germany), a secondary data analysis for the incidence, treatment characteristics and course of CDI was performed. The database included high granular accounting information of about 1.46 million medically insured patients covering the period 2006–2013, being representative for Germany. The analysis was based on new-onset CDI in 2012 in patients which either received outpatient antibiotic therapy for CDI or were hospitalized.ResultsThe ICD-10 coded incidence of CDI in 2012 was 83 cases per 100,000 population. Overall mortality rates within the follow-up period of 1 year were 13.5% in inpatients with primary diagnosis of CDI, compared to 24.3% in inpatients with secondary diagnosis of CDI (P < 0.001), and 7.1% in outpatients (P < 0.001). In the median, patients with secondary diagnosis of CDI remained significantly longer hospitalized (24 vs. 9 days, P < 0.001). First recurrence of CDI was observed in 18.2% of cases with index events. There was a significantly increased risk to suffer a second and third recurrence, reaching 28.4% (P < 0.001), and 30.2% (P = 0.017), respectively. Antibiotic therapy of CDI in outpatients was performed mainly with metronidazole (in 90.8% of index events, 60.0% of first recurrences, and 43.5% of second recurrences).ConclusionThe reported incidence of CDI in Germany is higher than noted previously. The recurrence rates do increase with the number of relapses, but are lower than reported in the literature, despite dominance of metronidazole treatment in outpatients.FundingMSD Sharp & Dohme GmbH, Haar, Germany.

Background Pyogenic liver abscesses (PLAs) represent potentially life‐threatening abdominal conditions that require immediate diagnosis and therapy. European and American incidence figures vary between one and 15 per 100,000 per year. Structured epidemiological data for European countries are not available. Objective To systematically characterize the epidemiology and clinical outcome of PLA in Germany. Methods In representative statutory health insurance data from four million people in 2013–2019, the prevalence and incidence with clinical coding of International Statistical Classification of Diseases and Related Health Problems (ICD)‐10 code K75.0 were selected (n = 1118). Furthermore, demographics, relevant comorbidities, hospitalizations, mortality and complications were determined within one year. Results The incidence of PLA was approximately seven per 100,000. The average age at diagnosis was 66 years; 65% were male. Of these, biliary disease was documented in over 60% and infectious intestinal diseases were found in 21% within the same or previous calendar year. PLA patients had high comorbidity indices. Liver transplant status, malignancies of the liver and biliary system, liver cirrhosis and pancreatitis were strongly associated. Intensive care was documented in 27% of PLA cases. Nine percent died within 12 months, most with an underlying malignant disease. Conclusion Pyogenic liver abscess is a rare disease with high morbidity. Predisposing and risk factors include intestinal and biliary diseases as well as hepatic malignancies. Further research should focus on PLA therapy within prospective surveys and controlled clinical trials.
