Approximately 20 % of the population are affected by gastroesophageal reflux disease (GERD). The subjective clinical and objective pathological extent of the disease is highly variable and the underlying pathophysiological mechanisms extraordinarily diverse. ⋯ Currently, additional relevant pathophysiological cofactors are being detected with the continuous improvement in diagnostic methods and used for therapeutic decision-making. Despite standardization of the operative technique and increasing criticism on long-term proton pump inhibitor (PPI) therapy, antireflux surgery still requires a very critical assessment of indications based on a comprehensive diagnostic evaluation.

Acromioclavicular joint (ACJ) dislocation is a common injury to the shoulder girdle, especially in contact and high velocity sports. Besides the severity of the injury, and particularly in competitive and elite athletes and the type of sports, individual career plans and in and out of season injuries have to be taken into account when advising treatment for athletes. ⋯ High-grade ACJ dislocations in athletes should be treated surgically. Arthroscopic and arthroscopically-assisted techniques can offer a lower risk of infection, a higher patient acceptance in terms of cosmetic perspectives and the potential to treat concomitant glenohumeral lesions and may avoid potential disadvantages of open techniques, such as secondary obligatory implant removal and extensive soft tissue preparation with a relevant approach morbidity.

The majority of emergency patients are admitted to hospital via the emergency department. Overcrowding in emergency departments results in dissatisfied patients, increased complication rates, and negative medicoeconomic consequences. To overcome these problems, sufficient personnel strength should be available depending on treatment duration and the patients' characteristics. ⋯ The duration of treatment of an average trauma and orthopedic patient depends on the level of care of the hospital and the qualification of the physician in charge. In order to avoid negative consequences of overcrowding in emergency departments, adequate personnel strength is essential. Personnel strength should be calculated based on the average duration of medical treatment of about 18 min.

The treatment of patients with aneurysms of the ascending aorta and aortic arch often represents a challenge due to their complexity. The clinical picture is characterized by further progression of the disease and severe complications, such as acute aortic dissection or even aortic rupture are not uncommon. ⋯ An aortic aneurysm of the ascending aorta is defined as a dilatation of all wall layers of the aorta of more than 50 % in comparison to the normal diameter. This is dependent on age, sex, body surface area and the underlying diseases. In most cases the cause is the presence of atherosclerosis. Connective tissue diseases, bicuspid or monocuspid aortic valves and aortitis represent additional risk factors. Surgical treatment of the ascending aorta, aortic root and aortic arch is carried out in patients without connective tissue diseases and a diameter of ≥ 55 mm and for patients with Marfan syndrome and bicuspid aortic valves with a diameter of ≥ 50 mm. Earlier indications for surgery are present with an aortic diameter of ≥ 45 mm in patients with the following risk factors: familial disposition for aortic dissection (often unrecognized as sudden cardiac death), annual growth rate of the aortic diameter of > 2 mm, comorbid severe aortic valve or mitral valve insufficiency and female patients with a desire to have children. The standard surgical procedures include aortic root replacement, aortic valve reconstruction with aortic root or ascending aorta replacement and partial or total aortic arch replacement depending on the extent of the aneurysm. The so-called hybrid procedures for aortic arch surgery include frozen elephant trunk (ET) techniques and debranching procedures. Good perioperative and postoperative results can be achieved by early diagnostics and an assessment of the indications depending on the individual etiology. Individual and valve-preserving treatment strategies have a favorable influence on the operative outcome.
