It is known from current pathophysiology that disease stages I and II of truncal varicosity of the great saphenous vein do not cause changes in venous pressure on dynamic phlebodynamometry. This is possibly also the case for mild cases of the disease in stage III. In pronounced cases of stage III and all cases of stage IV, however, venous hypertension occurs which triggers the symptoms of secondary deep venous insufficiency and all the complications of chronic venous insufficiency. From these facts the therapeutic consequence is inferred that in stages I and II and perhaps also in very mild cases of stage III disease, it is enough "merely" to remove varicose veins without expecting there to be any other serious complications in the patient’s further life caused by the varicosity. Recurrence rates are not included in this analysis. In marked cases of disease stages III and IV of the great saphenous vein, however, secondary deep venous insufficiency is to be expected sooner or later. The classical operation with saphenofemoral high ligation ("crossectomy") and stripping strictly adheres to the recognized pathophysiologic principles. It also takes into account in the greatest detail aspects of minimally invasive surgery and esthetics. In the past few years, developments have been advanced to further minimize surgical trauma and to replace the stripping maneuver using occlusion of the trunk vein which is left in place. Obliteration of the vessel is subsequently performed via transmission of energy through an inserted catheter. This includes the techniques of radiofrequency ablation and endovenous laser treatment. High ligation is not performed as a matter of principle. In a similar way, sclerotherapy using microfoam is minimally invasive in character. All these procedures may be indicated for disease stages I and II, and with reservations also in mild forms of stage III disease. Perhaps high ligation previously constituted overtreatment in some cases. Targeted studies are still needed to prove whether secondary deep venous insufficiency can be avoided in advanced stages of varicose vein disease without high ligation and thus without exclusion of the whole recirculation circuit.

Cholangiokarzinome oder cholangiozelluläre Karzinome (CCC) sind seltene Tumoren des biliären Systems mit einer Inzidenz von 2–4/100000 pro Jahr. Zu ihnen zählen die perihilären Gallengangskarzinome (Klatskin-Tumore), mit ca. 60% das häufigste CCC, die peripheren (intrahepatischen) Cholangiokarzinome, das Gallenblasenkarzinom, die Karzinome der extrahepatischen Gallengänge und das periampulläre Karzinom. Zum Zeitpunkt der Diagnose ist nur bei etwa 20% eine chirurgische Resektion als einzige kurative Therapieoption möglich. Die Lebertransplantation ist wegen der hohen Rezidivrate derzeit nicht indiziert. Die Prognose von nicht resektablen Cholangiokarzinomen ist mit einer mittleren Überlebenszeit von sechs bis acht Monaten schlecht. Eine wirksame Therapie zur Verlängerung der Überlebenszeit existiert aktuell nicht. Die wichtigste Massnahme im Rahmen der «best supportive care» ist die Beseitigung der Cholestase (endoskopisch, perkutan oder chirurgisch), um einer Cholangitis oder Cholangiosepsis vorzubeugen. Durch eine systemische Chemotherapie lassen sich Ansprechraten von ca. 20% erreichen. 5-FU und Gemcitabine sind die derzeit am häufigsten eingesetzten Substanzen, die mit einer perkutanen oder endoluminalen Bestrahlung kombiniert werden können. Multimodale Therapiekonzepte können im Einzellfall erfolgreich sein, müssen jedoch erst in Evidence-Based-Medicine-gerechten Studien evaluiert werden, bevor Therapieempfehlungen für die Praxis formuliert werden können.

The primary treatment of resectable CRC is surgical resection. Postoperative adjuvant therapies are recommended when lymph node metastases are found (stage III). There is evidence that about 20% of node negative CRC cases (stage II) are understaged, i.e., they are actually node positive (stage III). New intraoperative procedures (lymphatic mapping and sentinel node identification) that are able to detect occult macro- and micrometastases. Molecular assessment of nodal disease should improve the current staging criteria for colon cancer and could influence recommendation for adjuvant treatment.
