Surgical resection is the consistent component of curative treatment strategies for primary malignant diseases of the stomach and the esophagus. The placement of anastomoses for the necessary reconstruction still accounts for substantial morbidity and in the case of a failure to rescue also for mortality, especially for esophagojejunostomy and esophagogastrostomy. The diagnostics of anastomotic leakage routinely involve computed tomography and endoscopy and timely performance appears to be essential. Endoscopy can simultaneously initiate the essential treatment step. A major reason for the improvement of postoperative outcomes after resection in the upper gastrointestinal tract in the last decades is the successful and mostly endoscopically performed management of anastomotic leakage, whereby different endoscopic treatment options are now available. Endoscopic vacuum therapy has become established as the standard, normally with an endoscopic vacuum sponge technique but is also now supplemented by a combination system of vacuum sponge and stent. Furthermore, a foil-coated multiple lumen nasogastric tube represents another available option, which can possibly especially be used as a prophylactic measure. The longest established endoscopic therapy option for anastomotic leaks, the endoluminal metal stent, has been replaced as the standard by the vacuum treatment but is still used in suitable situations. Additionally, there are endoscopic suture devices that are currently only used very occasionally. Surgical revision is always available as treatment escalation but is only recommended for very early occurrences and possibly technically related anastomotic leakage and in the case of failure of endoscopic treatment. This article describes and summarizes the diagnostics and treatment of anastomotic leakages after surgical procedures of the upper gastrointestinal tract.

Severe complications following hepato-pancreato-biliary surgery are frequently due to leakage of anastomoses. Local intraoperative and systematic measures can reduce the incidence of leaks and leak-related sequelae. The early identification of leak-related sequelae, such as hemorrhage is pivotal to reduce the mortality risk. Therefore, perioperative risk stratification incorporating surgical and patient risk factors is crucial. The management of anastomotic leaks is complex and an interdisciplinary treatment is therefore recommended. The treatment depends on the institutional expertise, localization, characteristic features of the anastomosis and the onset of insufficiency. This article describes the different concepts of the diagnostics, prevention, consequences and management of anastomotic leakage in hepato-pancreato-biliary surgery in more detail.

Background: Botulinum toxin application into the abdominal wall prior to major hernia repair can reduce the complexity of surgery and has been increasingly used in recent years, even if it is an off-label use.

Objective: To what extent is botulinum toxin used in hernia surgery in German-speaking countries and what is the current evidence in the literature?

Material and methods: In a voluntary online survey of German Society for General and Visceral Surgery (DGAV)-certified competence centers and reference centers for hernia surgery, aspects of botulinum toxin application were surveyed and the results analyzed.

Results: A total of 57 centers took part in the survey, of which 27 (47%) use botulinum toxin. The main reasons for not using it were lack of experience and reimbursement. Of the centers 85% have treated less than 50 patients with botulinum toxin. The main indications were midline hernias (M2-4 according to the EHS classification) with a hernia gap > 10 cm (W3 according to EHS classification) and loss of domain situations. The application was predominantly ultrasound-guided by designated hernia surgeons with 100-200 Allergan or 500 Speywood units 4-6 weeks preoperatively and without complications related to the botulinum toxin application.

Conclusion: Botulinum toxin injections in hernia surgery appear to be safe and effective. Ultrasound-guided preoperative bilateral administration is supported by the available data. Specific course and information formats should be offered by the hernia surgery institutions.

A leakage of a colorectal anastomosis represents a severe complication in visceral surgery. An anastomotic insufficiency (AI) is a potentially life-threatening complication for patients that carries a high risk of subsequent complications and long-term stoma care. Numerous factors influence the risk of AI. Knowing and being able to estimate these factors are essential for successful treatment in colorectal surgery as they help determine the surgical strategy. The recognition of an AI can be challenging for practitioners due to the variability in the clinical presentation. If the presence of AI is suspected appropriate diagnostic measures must therefore be taken. If an AI has occurred a colorectal specialist should definitely be involved in the treatment as this can significantly reduce further complications and the rate of permanent stomas.

Background: The incidence of syphilis has clearly increased in Germany in recent years. This infectious disease has many forms of manifestation and can imitate surgical diseases.

Material and methods: Comprehensive footage of experiences in a proctological center demonstrates these manifestations and explains the correct management.

Results: The likelihood of confusion of syphilis with anal fissures, anogenital warts, proctitis and rectal cancer is high.

Conclusion: Surgeons can encounter syphilis, the "chameleon of medicine" and must know the differential diagnoses.
