Accordingly, precise handling of the dissected lymph nodes is important for histopathological work-up. The authors have developed a lymph node plastic tray shaping the abdomen and pelvis in which the dissected lymph nodes are placed in its determined location. This can be applied for any urologic cancer surgery. The research was designed to test the usage of a new histological tray. The objective was to assess how helpful it was for the surgical team and in the pathological process. The newly developed lymph node tray has been applied in 150 urological cancer surgeries and its efficacy and outcome have been evaluated in all these cases by involved doctors and assistants. This new tray simplifies lymph node removing and identification (staging), making it safer and quicker in any uro-oncological surgery. It facilitates the work of the pathologist and the flow of reliable information along the surgeon—pathologist-oncologist team. With usage of the tray, lymph node dissections are more structured by methodical means compared to any of the present methods.展开更多

The role of preoperative and palliative biliary drainage has long beendebated. The most common techniques are endoscopic retrograde cholangiopancreatography(ERCP) and percutaneous transhepatic biliary drainage (PTBD);however, recently developed endoscopic ultrasound-assisted methods are gainingmore atention. Selecting the best available method in any specific scenario iscrucial, yet sometimes challenging. Thus, this review aimed to discuss theavailable techniques, indications, perks, pitfalls, and timing-related issues in themanagement of hCCA. In a preoperative setting, PTBD appears to have someadvantages: low risk of postprocedural complications (namely cholangitis) andbetter priming for surgery. For palliative purposes, we propose ERCP/PTBDdepending on the experience of the operators, but also on other factors: the levelof bilirubin (if very high, rather PTBD), length of the stenosis and the presence ofcholangitis (PTBD), ERCP failure, or altered biliary anatomy.展开更多
