Laparoscopic pancreatic surgery is not common practice in Germany and is only carried out in approximately 20 clinics but with an increasing trend. The reasons for this are manifold, such as the current selection of patients and both skills in laparoscopic and pancreatic surgery are necessary to perform this operation safely. In 2008 a registry called "Laparoscopic pancreatic surgery" was implemented to collect enough data in Germany to find out whether the resection is safe, feasible and beneficial for the patient.For further development of new laparoscopic techniques new data is needed. A group of experts performing laparoscopic pancreatic surgery in Germany supplied their data for the German registry for laparoscopic pancreatic resection and a consensus conference about the indications became necessary. This consensus conference discussed in particular the indications for laparoscopic pancreatic resection. A consensus was found by all members of the conference utilizing currently available evidence-based data.It was suggested that all data of laparoscopic pancreatic surgery should be evaluated in the German Registry. A consensus was made which diseases were either suitable for laparoscopic resection or not suitable or suitable in selected cases.

Diagnostics and therapy of anorectal disorders remain a surgical question. In close cooperation between different departments (radiology and gastroenterology, urology and gynecology, dermatology and psychology), the role of radiologic imaging is of growing importance. Exact knowledge of functional anatomy and precise clinical examination constitute the basis of the according therapeutic strategies. In this context radiology has contributed decisively. Developments in imaging techniques, e.g. dynamic MRI, highly contributed to better understanding of complex functional pelvic floor disorders. The combination of nanotechnology and high-resolution imaging allows precise staging, especially in rectal cancer. Furthermore, advances in virtual colonoscopy could lead to widely acceptable and patient-friendly screening for colorectal malignancies.

Diagnostics and therapy of anorectal disorders are still questions of surgery. Exact knowledge of functional anatomy and precise clinical examination constitute the basis for the resulting therapeutic strategies. Three-dimensional endosonography and technical advances in flexible endoscopy using high-resolution chromoendoscopy and narrow-band imaging enable exact staging and diagnosis, even of malignancies in earliest stages. Furthermore new in-vivo staining methods combined with high-resolution imaging facilitate the discrimination of inflammatory and neoplastic lesions, which often lead to diagnostic difficulties in chronic inflammatory bowel disease. Developments in neurologic testing, including surface electromyography and sacral nerve stimulation, complement the diagnostic armamentarium.

Applying the principle "practice makes perfect" to interventional medicine would mean that surgeons and departments with high treatment volumes for special procedures should have better results than low-volume institutions. In the last three decades several studies were published dealing with the association of therapy volume and treatment quality, e.g. in oncologic and vascular surgery as well as interventional cardiology. Concerning colorectal cancer it has been shown that an individual surgeon's case load is important but by far not the only therapy-associated prognostic factor. For example interdisciplinarity and multimodality including adequate pathological classification are no less important. For continual improvement of clinical outcome, quality management and control will grow in importance. Thus, it is necessary to develop structures and to specify standards for colorectal surgery. Based on the data available it is not yet possible to define minimum volumes for colorectal surgery.

Minimizing the access trauma of surgical interventions is becoming an essential task in modern surgery in order to make the treatment more comfortable for the patient. Minimally invasive surgery has had a major impact on the improvement of surgical results over the last decade. This is why such surgery is often named as the third patient friendly revolution in surgery after the introduction of asepsis and anesthesia. Operations that caused a huge strain on the patients in the past and led to immense costs for society because of the patient's lost working time and extensive rehabilitation, have lost their fear thanks to this technique. The physical strain is lower, the cosmetic effect is considerable and the costs for society might be reduced due to the significantly shorter duration of convalescence. Despite its known advantages, which have been reported in numerous studies, minimally invasive surgery has recently gained increased interest because of the installation of new accounting systems as well as strict budgeting and restricted resources. Realistic cost-benefit analysis and objectified quality controls are needed in order to guarantee innovative and patient friendly basic approaches in medicine in the future.

Acute abdomen is not a disease in itself but a description of a complex of symptoms combined with severe abdominal pain developed within a time frame of less than 24 h. All strategies for the management of acute abdomen underline the need for an interdisciplinary approach to diagnosis and therapy. This requires focused and intelligent use of efficient diagnostic procedures. Diagnostic laparoscopy may be a key to solving the diagnostic dilemma of unspecific acute abdomen. Furthermore, it allows not only direct inspection of the abdominal cavity but also surgical intervention, if needed. In particular the rate of negative laparotomies can be reduced.

It is not easy to define haemorrhoidal complaints precisely since this automatically means the entire aetiology and pathogenesis. What Stelzner describes as a complex compound of arteriovenous links in the rectal mucosa with an interlace of unstriated muscles, elastic fibres and connective tissue forms the anatomic base of the "corpus cavernosum recti". This cavernous vascular padding is a crucial component of the continence organ and ensures a gas-tight seal. According to Thomson's studies, haemorrhoids are to be regarded as a consequence of the disintegration of muscular and elastic components, caused by a distal shift of the vascular padding. The changes can cause growth up to prolapse, as well as haemorrhage or congestion. The reasons have not yet been conclusively clarified. Malfunctioning intestines--in particular constipational changes with hard stool--seem to be causal factors. The mechanisms of function and control of arteriovenous links as well as the influence of hereditary, social and cultural disposition continue to be unclear.

Within the framework of interdisciplinary palliative treatment strategies for gastrointestinal neoplasms, surgical therapeutic options are of essential importance. They are dominated by the reconstruction of the gastrointestinal passage, ensuring drainage of secretion and the alleviation of pain. Conventional, minimal-invasive and endoscopic procedures are employed individually or in a combined way, integrating all conservative therapies. In many cases, an unnecessary laparotomy with its high morbidity, mortality and prolonged hospitalisation can thus be avoided. This paper describes and discusses current surgical and endoscopic techniques for the palliative treatment of patients suffering from advanced gastrointestinal malignant tumours.
