Moral Inequity in Organ Donation: An Examination of Age-Based Denial.

The decision to donate an organ is often the decision to save a loved one's life. Frequently recognized as an ultimate act of altruism, a person's choice to donate is embedded in their right to make decisions about their own body and well-being, free of coercion. To ensure donors are truly acting out of altruism, transplant professionals will not allow someone to donate if there are concerns of duress or inability to consent.

Obesity, organ failure, and transplantation: a review of the role of metabolic and bariatric surgery in transplant candidates and recipients.

Obesity is a risk factor for kidney, liver, heart, and pulmonary diseases, as well as failure. Solid organ transplantation remains the definitive treatment for the end-stage presentation of these diseases. Among many criteria for organ transplant, efficient management of obesity is required for patients to acquire transplant eligibility.

Mesangial Expansion by Morphometry at 5 y After Kidney Transplantation: Incidence, Risk Factors, and Association With Graft Loss.

Background: Mesangial expansion (ME) is an understudied histologic lesion in renal allografts. The current Banff score is not reproducible and may miss important ME features. The study aimed to improve the quantification of ME using morphometry, assess changes over time, and determine its association with allograft loss.

Bariatric surgery and the diseased kidney: a 5-year assessment of safety and postoperative renal outcomes.

Background: Obesity and its related medical conditions are well-established contributors to the development of chronic kidney disease (CKD). Metabolic and bariatric surgery (MBS), including procedures such as sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB), is a potential intervention for these individuals. However, the heightened risk of postoperative complications casts doubts on the suitability of MBS in this population.

Outcomes of bariatric surgery in the setting of compensated advanced chronic liver disease associated with clinically significant portal hypertension: a multicenter, retrospective, cohort study on feasibility and safety.

Background: The obesity epidemic has led to an increase in the proportion of patients with chronic liver disease due to metabolic associated steatosic liver disease and in the prevalence of obesity in patients with cirrhosis. Metabolic and bariatric surgery (MBS) has been proven to determine weight loss, obesity-related medical problems remission, and liver steatosis, inflammation, and fibrosis improvement. However, cirrhosis and portal hypertension are well-known risk factors for increased morbidity and mortality after surgery.

Futility and poor outcomes are not the same thing: A clinical perspective of refined outcomes definitions in liver transplantation.

The term "futility" in liver transplantation is used inappropriately and inaccurately, as it is frequently applied to patient populations with suboptimal outcomes that are often not truly "futile." The term "futile" is used interchangeably with poor outcomes. Not all poor outcomes fulfill a definition of futility when considering all viewpoints.

Revitalizing pancreas transplantation: creation of a hands-on training course for pancreas allograft procurement, backbench preparation, and transplantation.

Despite a steady increase in the number of organs available for transplant in the United States, over the last two decades there has been a precipitous decrease in the annual number of pancreas transplants performed. One overlooked consequence of this decline in pancreas transplant volume has been a decrease in experience in proper pancreas procurement and transplantation techniques for transplant surgeons as well as fewer trained abdominal transplant fellows entering the workforce certified for pancreas procurement and transplantation, with those achieving certification having less-developed judgment, skills, and experience. To augment current fellowship training and provide a concentrated experience in pancreas procurement and transplantation, the ASTS developed a hands-on surgical skills workshop focused on proper techniques for pancreas allograft procurement and backbench preparation.

Obesity management for the hepatologist-What to do, how to do it and why?

Obesity is highly prevalent in hepatology clinics and has a significant impact on chronic liver disease and patient management. Hepatologists and gastroenterologists need to be actively engaged in the management of obesity. This review provides a detailed approach to this challenging comorbidity.

Nutritional Considerations for Patients With Renal Failure Undergoing Sleeve Gastrectomy.

Obesity is highly prevalent in patients with renal disease, as it contributes to or accelerates the progression of kidney disease and is frequently a barrier to kidney transplantation. Patients with renal disease have unique dietary needs due to various metabolic disturbances resulting from altered processing and clearance of nutrients. They also frequently present with physical disability, resulting in difficulty achieving adequate weight loss through lifestyle modifications.

Bariatric surgery and left ventricular assist device in patients with heart failure: A systematic review and meta-analysis.

Background: The role of metabolic and bariatric surgery (MBS), in synergy with left ventricular assist device (LVAD) implantation, in the scope of end-stage heart failure management for patients with severe obesity is not well elucidated.

Methods: We conducted a meta-analysis using Cochrane, Embase, PubMed, and Scopus databases to include articles from their inception to November 2022.

Results: A total of 271 patients who underwent MBS during or after the LVAD implantation were included from eleven separate studies.

Outcomes of Kidney Transplantation in Patients That Underwent Bariatric Surgery: A Systematic Review and Meta-analysis.

The impact of bariatric surgery (BS) on kidney transplantation (KT) outcomes in patients with obesity remains controversial. We systematically searched MEDLINE, EMBASE, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials for studies reporting outcomes of KT recipients that underwent prior BS. Common/random effects meta-analyses were performed to obtain summary ratios of the postoperative outcomes.

Guiding Kidney Transplantation Candidates for Effective Weight Loss: A Clinical Cohort Study.

Background: Obesity is increasingly common in kidney transplant candidates and may limit access to transplantation. Obesity and diabetes are associated with a high risk for post-transplant complications. The best approach to weight loss to facilitate active transplant listing is unknown, but bariatric surgery is rarely considered due to patient- and physician-related apprehension, among other factors.

Surprising neutral effect of shorter staple cartridges in laparoscopic sleeve gastrectomy.

Background: Consensus agreements regarding laparoscopic sleeve gastrectomy (LSG) advise against using staple loads less than 1.5 mm in closed staple height. However, few data exist to support this recommendation.

Increased staple loading pressures and reduced staple heights in laparoscopic sleeve gastrectomy reduce intraoperative bleeding.

Background: In laparoscopic sleeve gastrectomy, tissue thickness and closed staple height of the staple cartridge determine the pressure applied to the tissue. Prior studies have suggested 8 g/mm to be ideal to minimize leaks or bleeding.

Methods: We evaluated the relationship between staple loading pressure applied to gastric tissue and bleeding rate prospectively with a novel tissue measuring device and video-recorded operative findings for 116 patients undergoing laparoscopic sleeve gastrectomy performed by 2 surgeons at a single institution.

Impact of side-to-side cavocavostomy versus traditional piggyback implantation in liver transplantation.

Background: Traditional piggyback implantation has often been used in liver transplant; however, this technique may be hindered by difficult visualization and postoperative incidences of outflow obstruction. Side-to-side cavocavostomy is an alternative approach, but perioperative outcomes associated with this technique remain largely unknown.

Methods: In July 2017, side-to-side cavocavostomy was adopted as the standard implantation technique at our institution by all surgeons (n = 4).
