RESUMEN
Hospital-acquired conditions (HACs) are used to define hospital performance measures. Patient comorbidity may influence HAC development. The National Inpatient Sample database was used to investigate HACs for the patients who underwent liver transplantation. Multivariate analysis was used to identify HAC risk factors. We found a total of 13,816 patients who underwent liver transplantation during 2002-2014. Of these, 330 (2.4%) had a report of HACs. Most frequent HACs were vascular catheter-associated infection [220 (1.6%)], falls and trauma [66 (0.5%), catheter-associated UTI [24 (0.2%)], and pressure ulcer stage III/IV [22 (0.2%)]. Factors correlating with HACs included extreme loss function (AOR: 52.13, P < 0.01) and major loss function (AOR: 8.11, P = 0.04), hepatopulmonary syndrome (AOR: 3.39, P = 0.02), portal hypertension (AOR: 1.49, P = 0.02), and hospitalization length of stay before transplant (AOR: 1.01, P < 0.01). The rate of HACs for liver transplantation is three times higher than the reported overall rate of HACs for GI procedures. Multiple patient factors are associated with HACs, and HACs may not be a reliable measure to evaluate hospital performance. Vascular catheter-associated infection is the most common HAC after liver transplantation.

Chronic pancreatitis (CP), secondary to a wide variety of etiologies, is a progressive and irreversible disease. Initially, CP is managed with endoscopic interventions, long-term analgesia for its associated chronic abdominal pain syndrome and pancreatic enzyme replacement for exocrine dysfunction. As the disease advances, pancreatic drainage procedures and partial resections are considered, but they leave diseased tissue behind and usually result in short-term relief only. Total pancreatectomy alone is widely viewed as a last resort treatment option because it causes brittle diabetes mellitus. However, total pancreatectomy with islet autotransplantation (TPIAT) can prevent the development of diabetes and cure the chronic pain syndrome. One serious, albeit rare, complication of TPIAT is (partial) portal vein thrombosis. Its incidence is probably about 5%. To prevent the occurrence of portal vein thrombosis, we propose herein, and have successfully performed, continuous real-time Doppler ultrasonography during the islet infusion to study portal vein and intrahepatic flow patterns, as well as changes in Doppler signals. Flow and signal changes may allow for timely adjustment of the infusion rate, before a marked increase in portal vein pressure is noted and decrease the risk of portal vein thrombosis.

We describe a unique case of a 53-year-old woman who underwent a nonrelated living donor kidney transplant 9 years after a previous small bowel transplant from her sister. The patient had suffered from short bowel syndrome secondary to volvulus after undergoing bariatric surgery for morbid obesity. Her entire small bowel had to be resected emergently, but she also developed acute kidney failure at the time. This initial kidney injury associated with long-term exposure to calcineurin-inhibitor medication eventually led to end-stage renal disease. A successful kidney transplant from a different, nonrelated adult donor was performed. Of note, the unrelated kidney donor matched exactly the 2 HLA-A and HLA-B antigens that the recipient had not matched with her sister. We discuss the unique HLA configuration between the patient and her 2 living donors, the absence of posttransplant rejection and posttransplant immunosuppressive therapy. To our knowledge this is the first published report of a successful kidney after a previous bowel transplant using (2 different) living donors.

Appropriate metrics for performance analysis is an active topic of debate within the transplant community. This study explores current proposals on metric expansion as well as potential metrics and prospective collaborations that have not received widespread discussion within the transplant community. The premature introduction of additional, nonvalidated metrics risks behaviors that may undermine donor utilization and patient access to transplantation.

BACKGROUND: The Scientific Registry of Transplant Recipients (SRTR) has released a 5-tier performance ranking system based upon results of deceased-donor and living-donor liver transplantation. MATERIALS AND METHODS: An analysis of Spring 2017 SRTR Program Specific Reports for outcomes of adult living-donor and deceased-donor liver transplantation. RESULTS: Utilizing the current SRTR performance algorithm, living-donor liver transplant results may disproportionately affect transplant center performance ranking. CONCLUSION: Improvements in SRTR performance ranking including transparency in outcomes calculation, a calculating tool for transplant centers, and the potential reporting of living-donor outcomes as a separate report are necessary.

BACKGROUND: Until recently, transplantation from hepatitis C-positive donors was relatively contraindicated as eradication of active hepatitis C previously required an interferon-based regimen that has been associated with rejection in solid organ transplantation. New interferon-free treatment regimens for hepatitis C have fewer adverse events and higher cure rates than interferon-based regimens. Interferon-free regimens have been shown to be safe in the liver transplantation literature, but little is known about the safety and efficacy of treatment in heart transplantation. CASE DESCRIPTION AND DISCUSSION: Here we report a case of successful eradication of hepatitis C with a non-interferon-based regimen using ledipasvir-sofosbuvir following combined orthotopic heart and liver transplantation. Based on the prevalence of hepatitis C in the general population, inclusion of hepatitis C-positive donors for heart transplantation can expand this component of the donor pool 3- to 6-fold. CONCLUSIONS: In carefully selected patients and recipients, inclusion of hepatitis C-positive donors may allow for expansion of the donor pool.

The 2016 Annual Congress of the International Liver Transplantation Society was held in Seoul, South Korea in May. The 22nd Congress marked the largest multidisciplinary liver transplantation meeting in Asia since 2010. The principal themes were living donation, allocation, immunosuppression, machine preservation, novel treatment of hepatitis C, and expansion of the deceased-donor allograft pool. This report presents select abstracts from the scientific sessions within the context of the published literature to serve as a quick reference.

Hepatic function and pulmonary function are interrelated with failure of one organ system affecting the other. With improved therapies, patients with concomitant hepatic and pulmonary failure increasingly enjoy a good quality of life and life expectancy. Therefore, the prevalence of such patients is increasing with more presenting for both emergent and elective surgical procedures. Hypoxemia requires a thorough evaluation in patients with end-stage liver disease. The most common etiologies respond to appropriate therapy. Portopulmonary hypertension and hepatopulmonary syndrome are associated with increased perioperative morbidity and mortality. It is incumbent on the anesthesiologist to understand the physiology of liver failure and its early effect on pulmonary function to ensure a successful outcome.

Critical care of the general surgical patient requires synthesis of the patient's physiology, intraoperative events, and preexisting comorbidities. Evaluating an abdominal solid-organ transplant recipient after surgery adds a new dimension to clinical decisions because the transplanted allograft has undergone its own physiologic challenges and now must adapt to a new environment. This donor-recipient interaction forms the foundation for assessment of early allograft function (EAF). The intensivist must accurately assess and support EAF within the context of the recipient's current physiology and preexisting comorbidities. Optimizing EAF is essential because allograft failure is a significant predictor of recipient morbidity and mortality.

BACKGROUND: Primary abdominal wall reconstruction after liver transplantation presents a challenge in patients with size mismatch, multivisceral transplants, and prior recipient abdominal surgery. The authors report their experience with a novel technique for abdominal wall reconstruction with a new vascular composite allotransplant. METHODS: Five posterior rectus sheath-liver composite vascular allotransplants were procured by a multidisciplinary team and transplanted into four patients over the course of 2 years. Liver transplantation was performed in the standard manner, and the posterior rectus sheath was inset as an inlay flap. RESULTS: Abdominal wall integrity was reestablished with vascularized fascia in all five cases. In two cases, the fascia was closed immediately at the time of initial transplantation. In three cases, the abdomen was left open for a planned second look and closed definitively when the liver appeared satisfactory. In one patient, hepatic artery thrombosis was detected 11 days after transplantation, requiring a second posterior rectus sheath-liver transplant. Skin closure was performed for all transplants in either an immediate or a delayed fashion. Reoperation requiring elevation of the posterior rectus sheath flap for a suprahepatic vena cava stenosis was performed in one patient. CONCLUSIONS: Closure of the abdominal cavity is critical to the success of liver transplantation for organ survival and overall patient morbidity and mortality. The authors describe their institutional experience with a novel method of concurrent abdominal wall reconstruction and liver transplantation using the posterior rectus sheath-liver vascular composite allotransplant in situations of size mismatch, multivisceral transplants, and compromised abdominal wall of the recipient. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, V.

The disparity between organ supply and demand has necessitated more aggressive use of livers from extended criteria donors. Organ sharing between donor service areas and transplant centers in other regions is common. Confidence in the graft quality is greatly improved with a digital image taken in conjunction with the recovery surgeon's report and biopsy data. Three cases in which digital images of various levels of quality allowed the recipient's surgery to proceed, minimized the cold ischemia time, and yielded excellent outcomes are described. Another case in which a picture was not available and the liver was discarded after importation is also presented for comparison.

Clostridium perfringens sepsis following orthotopic liver transplantation (OLT) is a rare but reported complication that historically results in mortality or emergent retransplantation (ReTx). Complications from C. perfringens emphysematous gastritis have contributed to the death of a healthy live liver donor as well. Herein, we describe the first documented survivor of C. perfringens sepsis following OLT managed without laparotomy or emergent ReTx.

Transplantation-mediated alloimmune thrombocytopenia (TMAT) is donor-derived thrombocytopenia following solid-organ transplantation. To date, no clear consensus on the appropriateness of organ utilization from cadaver donors with a history of idiopathic thrombocytopenia purpura (ITP) has emerged. Herein is reported a devastating case of TMAT following liver transplantation utilizing an allograft from a donor with ITP that resulted in allograft failure. The literature is reviewed in this context to propose preliminary guidelines regarding utilization of allografts from cadaver donors with a history of ITP.

Because of organ shortage and a constant imbalance between available organs and candidates for liver transplantation, expanded criteria donors are needed. Experience shows that there are wide variations in the definitions, selection criteria, and use of expanded criteria donors according to different geographic areas and different centers. Overall, selection criteria for donors have tended to be relaxed in recent years. Consensus recommendations are needed. This article reports the conclusions of a consensus meeting held in Paris in March 2007 with the contribution of experts from Europe, the United States, and Asia. Definitions of expanded criteria donors with respect to donor variables (including age, liver function tests, steatosis, infections, malignancies, and heart-beating versus non-heart-beating, among others) are proposed. It is emphasized that donor quality represents a continuum of risk rather than "good or bad." A distinction is made between donor factors that generate increased risk of graft failure and factors independent of graft function, such as transmissible infectious disease or donor-derived malignancy, that may preclude a good outcome. Updated data concerning the risks associated with different donor variables in different recipient populations are given. Recommendations on how to safely expand donor selection criteria are proposed.
