RESUMEN

Nonalcoholic liver disease is a component of metabolic syndrome associated with obesity, insulin resistance, and hyperlipidemia. Excessive alcohol consumption may accelerate the progression of steatosis, steatohepatitis, and fibrosis. While simple steatosis is considered a benign condition, nonalcoholic steatohepatitis with inflammation and fibrosis may progress to cirrhosis, liver failure, and hepatocellular cancer. Studies in rodent experimental models and primary cell cultures have demonstrated several common cellular and molecular mechanisms in the pathogenesis and regression of liver fibrosis. Chronic injury and death of hepatocytes cause the recruitment of myeloid cells, secretion of inflammatory and fibrogenic cytokines, and activation of myofibroblasts, resulting in liver fibrosis. In this review, we discuss the role of metabolically injured hepatocytes in the pathogenesis of nonalcoholic steatohepatitis and alcohol-associated liver disease. Specifically, the role of chemokine production and de novo lipogenesis in the development of steatotic hepatocytes and the pathways of steatosis regulation are discussed.

RESUMEN

Limited case series describe conflicting results regarding the safety of checkpoint inhibitors (CPI) prior to liver transplantation (LT). We reviewed single-center data on all consecutive patients who underwent LT for hepatocellular carcinoma treated with CPI between January 1, 2018, and January 30, 2021. Time from CPI to LT, immunosuppression, biopsy-proven acute cellular rejection (BPACR), graft loss and death were evaluated. Five patients with a mean age 65 (range 61-71) years underwent LT after CPI with nivolumab. Time from last CPI to LT ranged from 0.3 to 11 months. Two patients with <3 months from the last dose of CPI to LT developed BPACR and severe hepatic necrosis, one of whom required retransplantation with recurrent BPACR but without recurrent graft loss over 38 months of follow up. None of the patients who underwent LT >3 months from the last dose of CPI had BPACR. In conclusion, pretransplant use of CPIs, particularly within 90 days of LT, was associated with BPACR and immune-mediated hepatic necrosis. Future multicenter studies should consider a sufficient interval from the last dose of CPI to LT to mitigate the risk for adverse immune-mediated outcomes and graft loss.

RESUMEN

INTRODUCTION: Complications are often under-reported at surgical morbidity and mortality (M&M) conferences due to the sole reliance on voluntary case submission. While most institutions have databases used for targeted initiatives in quality improvement, these are not routinely used for M&M. We aimed to increase case capture for M&M conferences by developing a novel system that augments the existing case submission system with cases representing complications from quality improvement databases and the electronic health record (EHR). METHODS: We developed and implemented a novel system for increasing the capture rate of complications for M&M conferences by developing custom software that combines data from the following sources: an existing voluntary case submission system for M&M, local quality databases-National Surgical Quality Improvement Program and Vizient, and an EHR-based case capture tool. We evaluated this system on a retrospective cohort of all postoperative complications at a single center in a 32-mo period and in a prospective cohort over a 4-mo period after system implementation. RESULTS: In the retrospective cohort, we identified 433 complications among all data sources. Inclusion of the new system introduced 280 new potential cases for M&M review over the 32-mo period. After implementation, the system provided 31% of cases presented at M&M conference that would have otherwise been omitted. CONCLUSIONS: A novel system that includes complications identified in the EHR and quality improvement databases increased the case capture volume for surgical M&M conference, which provides an objective case referral system that can identify complementary quality improvement opportunities.

RESUMEN

Growing research supports an increased survival benefit of combined heart and kidney transplantation in patients with both heart and renal failure. As a result, the frequency of these combined transplants continues to increase. Despite this trend, little has been done to quantify the impact of chronic illness in this population. We identified adult recipients of combined heart-kidney transplant from the Scientific Registry of Transplant Recipients (SRTR) database between 2005 and 2018. We focused on renal disease secondary to diabetes and duration of dialysis as markers of chronic illness. The primary outcome was post-transplant mortality. Our final multivariable Cox proportional hazard model found that diabetes-associated renal disease (HR 1.57, 95% CI 1.14-2.15, p = .01) and dialysis duration (HR 1.08, 95% CI 1.01-1.15, p = .02) were significant predictors of post-transplant mortality. Given the significant impact of dialysis duration and renal disease secondary to diabetes mellitus, these chronically ill patients should be closely examined for conditions such as peripheral vascular disease and frailty, which have been shown to affect mortality in heart transplant recipients and are prevalent in the chronic dialysis population.

RESUMEN

GOAL: We aimed to assess the incidence rate of coronavirus disease 2019 (COVID-19) in vaccinated versus unvaccinated solid organ transplant recipients (SOTR) at our center. METHODS: We abstracted the following clinical data from our transplant registry from 1/1/2021 to 6/2/2021: demographics, details of COVID-19 vaccination, incidence of COVID-19, and related mortality. We calculated incidence of symptomatic COVID-19 per 1000/person days at risk and incidence rate ratio (IRR). RESULTS: Among 2151 SOTRs, 912 were fully vaccinated, and 1239 were controls (1151 unvaccinated, 88 partially vaccinated). Almost 70% of vaccinated subjects received the mRNA-1273 vaccine. There were 65 cases of COVID-19 that occurred during the study period - four occurred among fully vaccinated individuals and 61 among controls (including two in partially vaccinated individuals). Incidence rate for COVID-19 was 0.065 (95% CI 0.024-0.17) per 1000 person days in vaccinated versus 0.34 (95% CI 0.26-0.44) per 1000/person days in the control group; IRR was 0.19 (95% CI 0.049 -0.503, p < 0.005). There were no COVID-19 related deaths in the four breakthrough infections and two of 61 (3.3%) among controls. CONCLUSION: We demonstrate real world clinical effectiveness of COVID-19 vaccination in SOTRs with an almost 80% reduction in the incidence of symptomatic COVID-19 versus unvaccinated SOTRs during the same time.

RESUMEN

BACKGROUND: Despite increased utilization of hepatitis C virus-infected (HCV+) organs for transplantation into HCV-uninfected recipients, there is lack of standardization in HCV-related patient education/consent and limited data on financial and social impact on patients. METHODS: We conducted a survey on patients with donor-derived HCV infection at our center transplanted between 4/1/2017 and 11/1/2019 to assess: why patients chose to accept HCV+ organ(s), the adequacy of their pre-transplant HCV education and informed consent process, financial issues related to copays after discharge, and social challenges they faced. RESULTS: Among 49 patients surveyed, transplanted organs included heart (n = 19), lung (n = 9), kidney (n = 11), liver (n = 4), heart/kidney (n = 4), and liver/kidney (n = 2). Many recipients accepted an HCV-viremic (HCV-V) organ due to perceived reduction in waitlist time (n = 33) and/or trust in their physician's recommendation (n = 29). Almost all (n = 47) felt that pre-transplant education and consent was appropriate. Thirty patients had no copay for direct-acting antivirals (DAA) for HCV, including 21 with household income <$20 000; seven had copays of <$100 and one had a copay >$1000. Two patients reported feeling isolated due to HCV infection and eight reported higher than anticipated medication costs. Patients' biggest concern was potential HCV transmission to partners (n = 18) and family/friends (n = 15). Overall almost all (n = 47) patients reported a positive experience with HCV-V organ transplantation. CONCLUSION: We demonstrate that real-world patient experiences surrounding HCV-V organ transplantation have been favorable. Almost all patients report comprehensive HCV-related pre-transplant consent and education. Additionally, medication costs and social isolation/exclusion were not barriers to the use of these organs.

RESUMEN

Every year the number of patients waiting for a heart transplant increases faster than the number of available donor organs. Some potential donor organs are from donors with active communicable diseases, including hepatitis C virus (HCV), potentially making donation prohibitive. The advent of direct-acting antiviral agents for HCV has drastically changed the treatment of HCV. Recently, these agents have been used to treat HCV in organ donor recipients who acquired the disease from the donor organ. We report a case of heart-kidney transplantation from an HCV viremic donor to HCV negative recipient with successful treatment and sustained virologic response.

RESUMEN

On June 18, 2013, the United Network for Organ Sharing (UNOS) instituted a change in the liver transplant allocation policy known as "Share 35." The goal was to decrease waitlist mortality by increasing regional sharing of livers for patients with a model for end-stage liver disease (MELD) score of 35 or above. Several studies have shown Share 35 successful in reducing waitlist mortality, particularly in patients with high MELD. However, the MELD score at transplant has increased, resulting in sicker patients, more complications, and longer hospital stays. Our study aimed to explore factors, along with Share 35, that may affect the cost of liver transplantation. Our results show Share 35 has come with significantly increased cost to transplant centers across the nation, particularly in regions 2, 5, 10, and 11. Region 5 was the only region with a median MELD above 35 at transplant, and cost was significantly higher than other regions. Several other recipient factors had changes with Share 35 that may significantly affect the cost of liver transplant. While access to transplantation for the sickest patients has improved, it has come at a cost and regional disparities remain. Financial implications with proposed allocation system changes must be considered.

RESUMEN

IMT, previously known as IPT, is a relatively rare tumor that was originally described in the lungs, but case reports have reported the tumor in almost every organ system. Surgical resection is typically the mainstay of therapy; however, tumors have also been shown to respond to chemotherapy or anti-inflammatory therapy and some have spontaneously regressed. We present a literature review and case report representing the first documentation to date of liver transplant combined with PD for surgical resection of a myofibroblastic tumor non-responsive to medical therapy.

RESUMEN

Although intra-operative vascular complications during renal transplantation are rare, injuries associated with prolonged ischemia may lead to graft threatening early and late complications. This series describes a novel technique for intra-operative repair of vascular complications in five patients over a three-yr period. The method consists of rapid graft nephrectomy and re-preservation of the graft with cold University of Wisconsin solution, which allows for controlled/precise back table repair of the vascular injury without incurring prolonged warm ischemia time. In three cases, the donor renal vein (2) and donor renal artery (1) were damaged and required back table reconstruction. In two cases, the recipient iliac artery needed reconstruction. Three of the five cases used deceased donor iliac vessels from another donor for reconstruction. Two patients required postoperative dialysis for delayed graft function for three to nine d (average six d) and two patients had slow graft function. All grafts were functioning at 17 months (mean) after transplant, with a median serum of 1.61 mg/dL (0.74-3.69). This series demonstrates the effectiveness of kidney clamp, perfuse, resuscitate as an effective intra-operative technique to salvage grafts after vascular injury. Although the grafts may suffer from delayed or slow graft function, excellent long-term function is attainable.

RESUMEN

Improved outcomes have been associated with various methods of size matching between expanded criteria (ECD) donors and recipients. A novel method for improved functional based matching was developed utilizing manipulation of Cockcroft-Gault estimated creatinine clearances for donor and recipient. We hypothesized that optimal clearance-based matches would have superior outcomes for both immediate graft function and long-term graft survival. For the analysis, recipients of ECD kidneys in the Scientific Registry of Transplant Recipients (SRTR) transplanted between October 1, 1987 and August 31, 2011 were included. Univariate and multivariate analyses predicted the hazard ratio of graft failure and the odds ratio of requiring dialysis within the first week. A total of 25,640 ECD kidney transplants were analyzed. On multivariate analysis, higher creatinine clearance match ratio (CCMR) was associated with increased graft failure and odds of requiring dialysis within the first week (comparing highest ratio quintile versus lowest ratio quintile: HR 1.43, p < 0.001; OR 2.08, p < 0.001). This study suggests that ECD kidneys have improved outcomes when the recipient/donor CCMR is optimized.

RESUMEN

INTRODUCTION: Effective communication in the operating room (OR) is crucial. Addressing a colleague by their name is respectful, humanising, entrusting and associated with improved clinical outcomes. We aimed to enhance team communication in the perioperative environment by offering personalised surgical caps labelled with name and provider role to all OR team members at a large academic medical centre. MATERIALS AND METHODS: This was a quasi-experimental, uncontrolled, before-and-after quality improvement study. A survey regarding perceptions of team communication, knowledge of names and roles, communication barriers, and culture was administered before and after cap delivery. Survey results were measured on a 5-point Likert Scale; descriptive statistics and mean scores were compared. All cause National Surgical Quality Improvement Project (NSQIP) morbidity and mortality outcomes for surgical specialties were examined. RESULTS: 1420 caps were delivered across the institution. Mean survey scores increased for knowing the names and roles of providers around the OR, feeling that people know my name and feeling comfortable communicating without barriers across disciplines. The mean score for team communication around the OR is excellent was unchanged. The highest score both before and after was knowing the name of an interdisciplinary team member is important for patient care. A total of 383 and 212 providers participated in the study before and after cap delivery, respectively. Participants agreed or strongly agreed that labelled surgical caps made it easier to talk to colleagues (64.9%) while improving communication (66.0%), team culture (60.5%) and patient care (56.8%). No significant differences were noted in NSQIP outcomes. CONCLUSIONS: Personalised labelled surgical caps are a simple, inexpensive tool that demonstrates promise in improving perioperative team communication. Creating highly reliable surgical teams with optimal communication channels requires a multifaceted approach with engaged leadership, empowered front-line providers and an institutional commitment to continuous process improvement.

RESUMEN

BACKGROUND: Living-donor liver transplantation (LDLT) has emerged as a viable strategy in an era of organ shortage. However, biliary strictures are a common complication of LDLT, and these strictures frequently require surgical revision after unsuccessful endoscopic therapy. The optimal endoscopic treatment for anastomotic biliary strictures (ABSs) after LDLT is undefined. OBJECTIVE: To determine the outcome of an aggressive endoscopic approach to ABSs after LDLT that uses endoscopic dilation followed by maximal stent placement. DESIGN: A retrospective study. SETTING: A tertiary-care academic medical center. PATIENTS: Forty-one patients with a diagnosis of ABS. INTERVENTIONS: Endoscopic retrograde cholangiography with balloon dilation and maximal stenting. MAIN OUTCOME MEASUREMENTS: Stricture resolution, stricture recurrence, and complication rates. RESULTS: Of 110 LDLTs completed, a biliary stricture developed after transplantation in 41 (37.3%), which included 38 patients with duct-to-duct anastomosis. The median (interquartile range [IQR]) follow-up time is 74.2 (2.5-120.8) months. Among them, 23 (60.5%) were male, and 20 (52.6%) had bile leakage associated with ABSs. The median time (IQR) to the development of an ABS after LDLT was 2.1 (1.2-4.1) months. Endoscopic retrograde cholangiography was attempted as initial therapy in all patients: 32 were managed entirely by endoscopic therapy, and 6 required initial percutaneous transhepatic cholangiography (PTC) to cross the biliary stricture, with endoscopic therapy performed thereafter. A median (IQR) of 4.0 (3.0-5.3) endoscopic interventions and 7.0 (4.0-10.3) stents were required to resolve the stricture. The time from the first intervention to stricture resolution was 5.3 (range 3.8-8.9) months. Biochemical markers including aspartate transaminase (76 vs 39 U/L, P = .001), alanine transaminase (127.5 vs 45.5 U/L, P < .001), alkaline phosphatase (590 vs 260 IU/L, P < .001), and total bilirubin (2.57 vs 1.73 mg/dL, P = .017) significantly improved after intervention. Recurrent stricture was observed after initial treatment in 8 (21%) patients. All recurrences were successfully re-treated endoscopically. All patients have been managed without surgical revision or retransplantation, resulting in 100% success by an intention-to-treat analysis. LIMITATIONS: Retrospective study, small sample size. CONCLUSIONS: In this series, aggressive endoscopy-based treatment with maximal stent placement strategy allows 100% resolution of all duct-to-duct ABSs after LDLT without the need for surgical intervention or retransplantation.

RESUMEN

Homeopathic remedies made primarily from eggshells, and therefore calcium, can be marketed for treatment of back pain and vaginal discharge. We present a case of a 23-year-old otherwise healthy woman who presented with acute liver failure (ALF) ultimately requiring liver transplantation as a result of taking increased doses of a homeopathic product with the primary ingredient of eggshells. Although relatively uncommon compared with medications such as acetaminophen, herbal supplements have been reported to cause drug-induced liver injury (DILI), thought to be primarily due to contaminants. This is the first known report of DILI resulting from a homeopathic product with the primary ingredient of eggshells, and it demonstrates the importance of early ALF recognition and treatment, as well as the importance of practicing caution when using homeopathic supplements.

RESUMEN

INTRODUCTION: Originally designed as a forum to discuss adverse patient events, Surgery Morbidity & Mortality Conference (M&M) has evolved into an integral tool within surgical education where trainees at all levels are taught to critically examine decision-making. Others have expanded the scope of subsets of M&M conferences to include additional factors that influence patient outcomes, such as social determinants of health, implicit bias and structural policies that contribute to health disparities. In this study, we implemented a disparities-based discussion into our surgical department's weekly M&M conference and examined the effect(s) on participants' understanding and perceptions of key disparities in access to surgical care. METHODS: An anonymous electronic survey was sent to attendees of the Department of Surgery's M&M conference including faculty, residents and medical students prior to implementation of the intervention. The survey queried perceptions of the presence and impact of disparities in access to surgical care and how these are addressed at the study institution. The standard presenter slide template was updated to include a "Disparities Factors" section within the "Reasons for Complication" slide. After over 1 year, a postintervention survey was sent to conference attendees that included the same questions as the initial survey, as well as new questions related to the intervention. Descriptive statistics were performed on survey results, and comparisons were made for paired pre-post items. RESULTS: Eighty conference attendees completed the pre-intervention survey, and 70 completed the postintervention survey (22 [27.5%]; 22 [31.4%] attendings, 24 [30.0%]; 21 [30.0%] residents, 34 [42.5%]; 27 [38.6%] medical students respectively). Socioeconomics and language were most commonly identified both pre- and postintervention as the most important factors contributing to disparities in care experienced by patients at the study institution. Respondents agreed disparities in access significantly impact surgical care, and there was an increase in the number of respondents who reported feeling that disparities are being addressed postintervention. A total of 69% (n = 48) of respondents thought that integrating discussion of disparities in access to surgical care into M&M improved their understanding of the role these disparities play, 66% (n = 46) felt that their own thinking or practice changed regarding patient disparities, 84% (n = 59) reported integrating these discussions of disparities into M&M has been helpful overall. CONCLUSION: The inclusion of a disparities discussion in weekly M&M conference has led to positive change at the study institution, fostering a more comprehensive and socially conscious dialogue within the Department of Surgery. Survey respondents agreed that disparities exist in access to surgical care, and that the intervention improved their perceptions of how the study institution addresses disparities. Respondents felt that the integration of a disparities discussion was overall helpful, improved their knowledge of disparities in access to surgical care, and impacted their plans to address disparities in their own practices.

RESUMEN

BACKGROUND AND OBJECTIVES: Turnover time (TOT), defined as the time between surgical cases in the same operating room (OR), is often perceived to be lengthy without clear cause. With the aim of optimising and standardising OR turnover processes and decreasing TOT, we developed an innovative and staff-interactive TOT measurement method. METHODS: We divided TOT into task-based segments and created buttons on the electronic health record (EHR) default prelogin screen for appropriate staff workflows to collect more granular data. We created submeasures, including 'clean-up start', 'clean-up complete', 'set-up start' and 'room ready for patient', to calculate environmental services (EVS) response time, EVS cleaning time, room set-up response time, room set-up time and time to room accordingly. RESULTS: Since developing and implementing these workflows, measures have demonstrated excellent staff adoption. Median times of EVS response and cleaning have decreased significantly at our main hospital ORs and ambulatory surgery centre. CONCLUSION: OR delays are costly to hospital systems. TOT, in particular, has been recognised as a potential dissatisfier and cause of delay in the perioperative environment. Viewing TOT as one finite entity and not a series of necessary tasks by a variety of team members limits the possibility of critical assessment and improvement. By dividing the measurement of TOT into respective segments necessary to transition the room at the completion of one case to the onset of another, valuable insight was gained into the causes associated with turnover delays, which increased awareness and improved accountability of staff members to complete assigned tasks efficiently.

RESUMEN

Here, we present a protocol for isolating human hepatocytes and neural progenitor cells from normal and nonalcoholic steatohepatitis livers. We describe steps for perfusion for scaled-up liver cell isolation and optimization of chemical digestion to achieve maximal yield and cell viability. We then detail a liver cell cryopreservation and potential applications, such as the use of human liver cells as a tool to link experimental and translational research.

Extirpation of polycystic kidneys for various medical reasons has been performed using many different approaches in attempts to limit morbidity from such a large operation. In indicated patients, it has usually been offered in a staged approach with renal transplantation to avoid graft complications. We published the first case of simultaneous laparoscopic bilateral native nephrectomy with kidney transplant in 2008. The present study shows our continued experience with offering this minimally invasive, single surgery alternative. The results are comparable to a staged laparoscopic approach with significantly shorter total hospital stay and one recovery for the patient and his/her family. OBJECTIVE: • To analyse the perioperative outcomes of native bilateral laparoscopic nephrectomy (BLN) with simultaneous kidney transplantation. PATIENTS AND METHODS: • From November 2000 to April 2011, 37 patients were seen for renal failure secondary to autosomal-dominant polycystic kidney disease (ADPKD) and underwent renal transplant with native nephrectomies at a single tertiary academic centre. • In all, 15 patients underwent BLN for ADPKD followed by simultaneous kidney transplantation. • The other 22 patients underwent BLN for ADPKD with kidney transplant performed at a separate setting. • Demographic data, perioperative outcomes, complications regardless of need for intervention, and graft function were analysed in both groups. RESULTS: • The combined surgery was completed without intraoperative complication in all cases. • The median total operative duration was 372 min, estimated blood loss was 300 mL with two patients requiring transfusion, and the median (range) hospital stay was 5 (3-7) days. • All patients had immediate graft function with additional relief of compressive symptoms. • In comparison to our staged cohort, the simultaneous group had a significantly shorter total hospital stay. • All other outcomes and complication rates were comparable. CONCLUSION: • In ADPKD, a less invasive laparoscopic approach for native nephrectomies with simultaneous renal transplant offers comparable morbidity without graft compromise and the convenience of one operation and one recovery for the patient.

RESUMEN

BACKGROUND: Adherence to opioid prescribing protocols after operations remains challenging despite published guidelines. Integration of these guidelines with the electronic health record could potentially improve their adoption. We hypothesize that implementing an electronic health record order set containing prepopulated tablet quantities tailored to surgical procedures based on published guidelines will decrease postoperative opioid prescription. METHODS: We conducted a 12-month prepost intervention study on adult patients who underwent appendectomy, cholecystectomy, inguinal or umbilical hernia repair, thyroidectomy, or parathyroidectomy at a single institution. An electronic health record order set was developed with prepopulated opioid tablet quantities reflecting the upper limit of published recommendations. The primary endpoint was change in morphine milligram equivalent prescribed postintervention and was analyzed using linear regression adjusting for age, race, procedure, and prescriber training level. Secondary endpoints were emergency department visits for pain-related issues and opioid refill rates. RESULTS: We identified 524 patients (mean age = 53, 51% male) in our baseline cohort and 433 patients (mean age = 52, 58% male) in our postintervention group. The mean morphine milligram equivalent prescribed was 62.6 and 50.4 for the preintervention and postintervention cohorts, respectively (P = .049). Thyroidectomies and parathyroidectomies achieved the largest decrease after intervention, which decreased to 42.6 morphine milligram equivalent from 79.7 morphine milligram equivalent preintervention (P < .001). Refill rate was 1.6% postintervention compared to 3.1% preintervention (P = .20), and emergency department visit for pain control rate was 0.2% post intervention and 2.5% preintervention (P = .005). CONCLUSION: An electronic health record tailored order set based on prescription guidelines is a safe, effective, and scalable intervention for decreasing opioid prescriptions after operations.

RESUMEN

Value-based, outcome-oriented care supported with innovative technology is the future of surgery. We established a novel fellowship in Perioperative Administration, Quality, and Informatics. The aim is to equip future surgeon scholars with the requisite knowledge base and skillset to serve as institutional leaders capable of transforming surgical healthcare delivery. The model was designed as a project-based, "operations-focused" education with supplemental didactics and mentored by surgical leaders and institutional executives. We describe our initial experience, successes, and challenges such that a similar model may be replicated elsewhere.
