Background: With the increasing efficacy of systemic therapy, liver transplantation plays an important role not only for hepatocellular carcinoma (HCC) but also for nonresectable intrahepatic cholangiocellular carcinoma (iCC), perihilar cholangiocellular carcinoma (phCC) and colorectal liver metastases (CRLM)., Aim: To review the current state of knowledge regarding the indications, patient selection and expected outcomes of liver transplantation for HCC, iCC, phCC and CRLM., Results: When combined with neoadjuvant locoregional therapy (LRT) and/or systemic therapy, patients with nonresectable HCC, iCC, pCC and CRLM confined to the liver can be successfully transplanted with 5‑year survival rates exceeding 65%. The key to success is strict patient selection, which includes oncogenetic (e.g., BRAFV600E mutation status) and clinical criteria indicative of individual tumor biology (tumor markers: alpha-fetoprotein, AFP/carbohydrate antigen 19‑9, CA19-9/carcinoembryonic antigen, CEA, stable response to neoadjuvant therapy) in addition to morphometric criteria., Conclusion: Liver transplantation offers the possibility of curative treatment even for nonresectable hepatic malignancies. A major limitation of this treatment is the lack of donor organs. Crucial for success is patient selection based on individual tumor biology., (© 2024.

In times of an unprecedented energy crisis, sustainability is becoming increasingly important. This development does not stop at medicine and especially at the operating room, where a considerable amount of greenhouse gases is produced. Due to this development, the question arises whether sterility, safety and service can be reconciled with a resource-saving use of medical devices. One goal here must be to replace disposables, which offer a high degree of sterility, with safely reprocessable reusables. Due to rising energy costs as well as supply bottlenecks, reprocessing of products offers increasing independence for the hospital. Furthermore, the move towards renewable energy for reusable products is visibly improving the carbon footprint. The independence gained by clinics also offers greater safety for patients, as the risk of unavailable materials is reduced. In addition to the goal of increasing the use of reusable items, the recycling of disposable products will also play an increasing role. Life cycle assessments will increasingly guide the optimal choice of products in this regard. In summary, these options offer the possibility of implementing the increasing need for sustainability in the OR., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

Background: Climate neutrality is the major aim of our generation. In order to be able to achieve this a net zero emission should be strived for in operating theaters., Objective: What does zero emission implicate for the operative sector? Which structural approaches already exist? Can zero emission surgery be achieved?, Material and Methods: Evaluation of published studies, discussion of fundamental research and expert recommendations., Results: Studies in England and Germany show that by structural alterations and strict sustainability structures net zero emission surgery seems to be feasible. In Germany the attention and awareness of the topic are greatly increasing and the first projects and studies have been launched., Conclusion: To achieve the aim of net zero emission by 2050 we must rapidly and significantly increase our efforts., (© 2023.

The German Transplant Law is the legal basis of the liver allocation system in Germany and is specified by the guidelines of the German Medical Association. These guidelines are based on current medical knowledge. The procedure of developing these guidelines was formalised and made transparent.This survey with 502 participants examines how four current aspects of the allocation system are perceived by different stakeholders (medical staff, patients on the liver transplant list or already transplanted, medical students and non-medical university personnel and students). A great majority of respondents considered the current organ allocation system to be fair. Physicians were given a great say on allocation rules. Most respondents assessed the chances of a patient on the transplant list to receive a donor organ over time as being worse than it really was. The respondents supported six month alcohol abstinence before patients with alcohol-related liver cirrhosis are listed for liver transplantation. The findings suggest that people trust that physicians develop fair allocation rules and appreciate the current liver allocation system., Competing Interests: Die Autoren geben an, dass kein Interessenkonflikt besteht., (Georg Thieme Verlag KG Stuttgart · New York.)

Currently, there is no structured training plan to become a transplant surgeon in Germany. Similar to the Anglo-Saxonian educational system we have implemented a 3-year fellowship in transplant and hepatic-, pancreatic-, biliary (HPB) surgery. The educational curriculum is based on the guidelines of the European Board of Surgery (EBS) for transplant and HPB surgery. Here, we describe the underlying thoughts, the selection process, structure and curriculum for this fellowship. Furthermore, we critically compare our programme to the established international training standards. So far, our programme has proven valuable. We believe a fellowship for transplant and HPB surgery is a reasonable approach to ensure a high quality training of the following generations of surgeons in this field., (Georg Thieme Verlag KG Stuttgart · New York.)

The blatant problem of organ shortage leads to an increasing acceptance of organs from extended criteria donors. This increases the importance of the process of organ donation and retrieval. A working group of representatives of Bavarian retrieval surgeons and the procurement organization German Foundation of Organ Transplantation (DSO) was initiated to develop consensus-based recommendations for quality improvements in the field of organ retrieval on the basis of regional data. The main aim was to professionalize retrieval teams by specified training standards and to define objective qualifications for retrieval surgeons. Initial measures of the working group included agreement on standardized retrieval techniques and improvement of documentation in terms of quality forms and the return rate of the forms. Quality data are being analyzed prospectively with a new categorization of complications. Communication among centers and teams and complication reporting has already been improved and initial structural changes have been set up.

Surgical problems during organ procurement may propagate complications in the transplant recipient. Ultimately, these problems may result in the complete loss of already scarce donor organs.Donor reports (Eurotransplant donor report) of 1,492 donor organs from January 2010 to August 2012 in the German Foundation of Organ Transplantation (DSO) region of Bavaria and corresponding organ quality forms were analyzed. Surgical problems were classified into 3 categories: (I) surgical problems recognized and reported by the donor surgeon, (II) surgical problems observed by the recipient surgeon but not reported by the donor surgeon and (III) surgical problems leading to organ loss. Surgical problems during this 20-month time period were reported for 17.6  % of organs; category I in 5.5  %, category II in 11.1  % and category III in 1  %. Damage of graft vasculature in 9.1  % was the most frequently reported problem. The mean error index for individual surgeons was 16  % and one out of the five Bavarian organ procurement centers had significantly more problems in all categories (30  %). Interestingly, surgeons who performed rapid retrieval procedures had more problems with quality than surgeons who took more time. Organ retrieval is prone to surgical problems. Especially in a system of organ transport, consistent reporting of surgical problems and quality assurance is needed to maintain and to improve surgical quality.

Malignant tumors represent a serious problem in transplantation medicine. Tumors passed on by the donor or present in the recipient's history may reappear after transplantation with its need for immunosuppression. On the other hand, in patients with hepatocellular carcinoma (HCC), transplantation is the sole curative therapeutic option. Chronic immunosuppression promotes not only a tendency for the disease to recur, but also the development of various solid and hematological malignancies, and thus makes rigorous prophylactic measures a must. The use of new immunosuppressants (mTOR inhibitors) might, in future, be useful in helping resolve the problem of malignant diseases in organ transplantation.
