What's Your Perspective?

  • How Do I Get on an ASTS Committee?

    The American Society of Transplant Surgeons is our organization. It exists because of the dedication of transplant surgeons, physicians, and other transplant professionals, who work together with the highly skilled staff of the ASTS to support our primary goal: to advance the field of transplant surgery through leadership, advocacy, education, and training. While there are several organizations working on issues related to organ transplantation, the surgical perspective, particularly as it relates to training and advocacy, is uniquely represented by the ASTS.

    If we did not have members who wanted to be involved, the organization would cease to exist. Maintaining your membership in the ASTS and attending the Winter Meeting (January 26-29, 2017) are essential to being engaged. However, many of you may be ready to increase your participation in the ASTS by joining one of the many committees responsible for the carrying out the Society’s mission. However, you may not be entirely clear on how the ASTS committee process works. Below is a list of common questions you may have as well as a description of the main duties of the various committees. If you have additional questions, please don’t hesitate to contact us.

    Q: When does the committee nominations process take place?

    A: The committee nominations period varies from year to year, depending on when ATC takes place. Nominations will open several months prior to ATC. All ASTS members will receive notification via email when nominations open.  In 2017, nominations will open in early January.

    Q: How does the nominations process work?

    A: Once nominations are open, members can nominate either themselves or one of their peers for a committee position. Nominations are made through Survey Monkey. Nominations stay open for several weeks, then close to allow time for appointments to be made prior to ATC. All nominees are notified either way via email a few weeks later, and new committee members begin their appointments during the Business Meeting at ATC.

    Q: How are committee appointments made?

    A: Committee appointments are made at the discretion of the current ASTS president. The president considers all nominations before making appointments. The top 6 committee choices are indicated on the nomination form, and a great deal of effort is made to place nominees in their first choice; however, this is not always possible, and the president tries to place each person in a committee where their strengths can be put to the best possible use.  Typically, there are more nominees than committee slots, so you may not be selected when you are initially nominated. Last year, there were 146 people nominated for 73 open positions.

    Q: How are committee chair and co-chair appointments made?

    A: Committee co-chairs (similar to vice-chair) are usually selected from current members of the committee. If a person currently on a committee would like to be considered for the co-chair position, there is space to indicate this in the nomination form. Committee co-chairs usually move into the chair position when the chair slot is open.

    Q: How long do committee appointments last?

    A: Committee chairs and members all serve 3-year terms. Co-chairs are appointed for one-year terms but may be reappointed for up to 3 years.

    Q: Does it help if there multiple nominations for the same person, and does it matter who nominates you?

    A: It is not necessary for multiple people to nominate the same person for a committee appointment. Only one nomination is necessary for the president to consider someone for a position, and typically the qualifications of the nominee and the needs of the committee are the most important factors.

  • Waste Not, Want Not: Determining the Fate of the Marginal Liver Allograft

    Dr. John SealJohn Seal, MD
    Transplant Surgeon
    Ochsner Health System

    The primary goal of liver transplantation is to reduce mortality and significant morbidity associated with end stage liver disease and hepatocellular carcinoma. To that end, the current allocation system in the United States is designed to prioritize patients with the highest risk of death as estimated by the MELD scoring system. However, significant variability in the quality of donor organs complicates this process. The presence of extended criteria donor (ECD) features such as advanced age, abnormal liver function tests, steatosis, and donation-after-circulatory death can negatively impact early allograft function and overall graft survival. Many transplant surgeons avoid or very selectively use these grafts in the highest MELD patients out of concern for early organ dysfunction not well tolerated by sicker patients. In the environment of severe organ shortage, transplant centers are left with the onerous task of balancing the risk of death on the waitlist versus the potential risks associated with expanded criteria allografts.  Each organ offer prompts the questions: Will this liver work in my sickest patient? If not, will it work in any of my listed patients? And, if it will only work in my lowest MELD patients, am I really offering a survival benefit?

    For the past several years, our center has adopted an aggressive approach to organ utilization based on the hypothesis that the potentially deleterious effects of marginal features can be minimized through careful patient selection and minimization of cold ischemia time. Recipient selection is focused on limiting surgical complexity to facilitate a rapid hepatectomy with minimal blood loss. We carefully consider the patient’s overall functional status and co-morbidities to help predict an adequate physiologic reserve to support hemodynamic stability during clamp and reperfusion periods. During the transplant evaluation process, patients are assigned a score of surgical risk to facilitate recipient selection when an ECD offer is received. The second key principle, minimization of cold ischemia time, is more complex—it requires robust logistics and communications with procurement coordinators as well as an OR staff and anesthesia team able to mobilize quickly and on short notice. We also have a routine practice of having two attending surgeons available for every case. By executing these details well, we can avoid the cumulative effects of even small delays in the process that can add hours to cold ischemia time.

    While the upper limit of recipient selection for ECD is easier to define (high MELD, ICU, frail, etc.), the lower limit is less clear. In keeping with the priorities of the allocation system, we approach each offer systematically working our way down the list of potential recipients from high MELD score to low. Our goal is to transplant the graft into the most appropriate patient with the highest MELD on the list. A majority of the recipients of imported grafts at our center have MELD scores between 18-25, a range where the survival benefit from transplantation is clear. For the lowest MELD patients (<18), we focus on patients with a disease burden that is not reflected in their MELD score such as marked ascites, debilitating encephalopathy, or early stage HCC tumors waiting to accrue exception points. Also, it is important to consider the MELD history of the patient, including prior episodes of increased MELD suggesting instability in the degree of compensation and likelihood of progressive liver disease in the future.

    What does it mean for a graft to “work”? Defining the terms of early allograft dysfunction is critical to evaluating the performance of ECD grafts. Since 2012, we have observed no significant difference in graft or patient survival comparing imported ECD grafts with standard donors, with both categories at or above expected. Certainly we have seen higher rates of elevated AST/ALT (>2000) in the ECD grafts, but typically it is transient and normalizes by the time of discharge from the hospital. At our center we put more weight on the markers of synthetic and metabolic function of the graft, namely INR, bilirubin, and lactate in the early post-transplant period. Using post-transplant MELD as a marker of graft function1, we see no difference in early graft function with ECD grafts.

    We believe nearly every donor liver offers a potential survival benefit for some listed patient. Accordingly, we have invested resources and experience to optimize outcomes using ECD grafts and to identify suitable recipients to achieve a survival benefit.  Currently in the United States, the distribution of aggressive centers and donor liver utilization varies significantly between regions.2,3 As we strive for parity in organ allocation across regions, some emphasis should be placed on the lack of uniformity in utilization. We should also continue to invest in the development of better diagnostics for graft assessment, including normothermic machine perfusion systems4 and metabolomic/proteomic approaches to biomarker discovery5. But in the meantime, the challenge is to employ donor-recipient matching strategies to optimize utilization of the non-perfect graft within an allocation system that prioritizes our sickest patients.

  • Should Pediatric Transplantation Have Separate Fellowship Surgical Requirements?

    Dr. Amy GalloAmy E. Gallo, MD
    Assistant Professor of Surgery (Abdominal Transplantation)
    Stanford University Medical Center

    Low case volume is being associated with worse surgical outcomes, and transplantation is not an exception to this finding (1,2). As programs continue to be scrutinized by regulatory bodies to meet outcome measures, there have been fewer programs in the United States committed to pediatric transplantation.  While the American Society of Transplant Surgeons has established surgical volume requirements for liver, kidney, pancreas, and small bowel for fellowship training program accreditation, there are no fellowship requirements specific to pediatric transplantation. Assuming that each organ requires specific individual training requirements—because of complexity of the underlying disease and technical variation—it can be argued that pediatric solid organ transplantation calls for vastly different medical and surgical approaches from those of the adult counterparts and, therefore, should have its own fellowship requirements per solid organ.

    In addition, the UNOS Pediatric Transplant Committee has recently gained momentum on a motion to improve the quality and safety of pediatric transplantation. By the current OPTN Bylaws, the primary surgeon and primary physician in a pediatric transplant program are not required to have pediatric training or experience. The Pediatric Transplant Committee identified that OPTN data from 1995-2010 showed significantly better unadjusted Kaplan-Meier graft and patient survival for kidney, liver, and heart recipients from 1995-2010 at higher volume centers. Higher volume centers were defined differently for each organ:  12 for kidney, 18 for livers, 8 for hearts, and 4 for lungs, respectively. Over the period from 1/1/05-7/31/14, 65.5% of kidney and 58.0% of liver programs performing pediatric transplants met these criteria. The proposal by the UNOS Pediatric Transplant Committee requires that each transplant center have a primary pediatric transplant surgeon who meets the current Bylaws for a Primary Surgeon in addition to having performed 12 pediatric kidneys or 18 pediatric livers and participated for at least 2 years in organ-specific pediatric transplantation care. This proposal was presented to the Membership and Professional Standards Committee (MPSC) in September 2015. The MPSC is supportive of the proposal overall with the caveat that there be at least one qualifying program in each region by the time the requirements take effect.

    If pediatric requirements are accepted, mandating similar volume criteria for surgical fellowship (performing 12 kidneys and 18 livers for pediatric certification) would convey the technical and management differences that exist in pediatric transplantation. Currently in the 119 modules the transplant fellows are required to complete in the ASTS Academic Universe, only 2 are specific to pediatric transplantation.

    With certification targets in place, applicants interested in pediatric transplantation can seek out programs that will satisfy the requirements.  Graduates of these programs may pave the way to a better understanding of these pediatric differences following completion of their training. They can embark on job opportunities that reflect their strengths or look to continue training with their deficits more clearly defined. That is not to say that someone with no pediatric fellowship training could not consider pediatrics as a job career, but like many graduates without pancreatic or intestine training, the understanding is that they will not lead a program without senior expertise and further exposure.

    What continues to set transplant surgeons apart from other surgical fields is their lifelong commitment to patients, the reason that many of us chose the field. Setting fellowship requirements in pediatric transplantation might emphasize to trainees that performing a transplant on children means understanding and commanding issues unique to this patient population, such as the impact of psychomotor development as well as psychosocial issues, bone disease, inherited and sporadic syndromes, metabolic diseases, urologic anomalies, the effects of life-long immunosuppression, non-adherence particularly amongst adolescents, post-transplant lymphoproliferative disorders, and anatomic considerations (3,4). Embracing this knowledge allows us to advance the field of pediatric transplantation and reinforce our commitment to take care of such a fragile patient population.
