[The acute (surgical) abdomen - epidemiology, diagnosis and general principles of management].
This review comments on epidemiology, diagnosis and general principles of surgical management in patients with acute abdomen. DEFINITION AND EPIDEMIOLOGY: The most common cause of acute abdominal pain is non-specific abdominal pain (24 - 44.3 % of the study populations), followed by acute appendicitis (15.9 - 28.1 %), acute biliary disease (2.9 - 9.7 %) and bowel obstruction or diverticulitits in elderly patients. Acute appendicitis represents the cause of surgical intervention in two-thirds of the children with acute abdomen. ⋯ Acute small bowel obstruction has previously been considered as a relative contraindication for laparoscopic management, but it has been shown in the meantime that laparoscopic treatment is an elegant tool for the management of simple band small bowel obstruction. Bedside diagnostic laparoscopy is recommended in intensive care unit (ICU) patients with acute abdomen or sepsis of unknown origin, in suspicion of acute cholecystitis, diffuse gut hypoperfusion and mesenteric ischaemia or in refractory lactic acidosis, especially after cardiac surgery. Early administration of analgesia to patients with acute abdominal pain in the emergency department will reduce the patient's discomfort without impairing clinically important diagnostic accuracy and is recommended on the basis of some prospective randomised trials. However, the impact on diagnostic accuracy depends on dosage, kind of application and cause of acute abdominal pain. A practice of judicious provision of analgesia therefore appears safe. There are significant differences between the knowledge of the current literature and the routine practice of providing analgesia as a survey has shown demonstrating that less than 50 % of paediatric emergency physicians and paediatric surgeons are usually willing to provide analgesia before definitive diagnosis.

The use of sedation (e. g., of short-acting propofol) for gastrointestinal endoscopy has shown an upward trend in the United States and Europe over the last decade. This survey aimed at providing nationwide data on the current practice of endoscopic sedation and monitoring in Germany. ⋯ Besides the common administration of short-acting benzodiazepines, sedation with propofol is also gaining ground in Germany; it is applied mainly in low doses (up to 150 mg). German endoscopists are highly satisfied with these sedation regimens, with propofol significantly leading the score. Patient monitoring predominantly follows currently prevailing guidelines.

International studies in the 1990 s and the HYGEA study from Germany in 2002 revealed prevalences of around 50 % of microbiological contaminations in reprocessed flexible endoscopes. Before introducing the colorectal cancer screening programme by colonoscopy in Germany in 2002, the Kassenärztliche Bundesvereinigung (KBV) and the key stakeholders of the public health insurance system agreed on a quality assessment assurance for reprocessing endoscopes where the qualification for refund for colonoscopies from the public health system was made conditional on adequate qualifications of the gastroenterologist; on a minimum number of performed procedures per year; and on adequate endoscope reprocessing documented by negative surveillance cultures two times per year. This study is an implementation and outcome evaluation of the quality assessment assurance in colonoscopy in Germany. ⋯ This study evidences 1. the successful implementation of the quality assessment assurance in Germany and 2. a substantial improvement in the quality of reprocessing flexible endoscopes achieved by these measures with a drop from 50 % of failed tests observed before the introduction in 2000 - 2001 to below 4 % in 2007.
