Bariatric surgery and end-stage organ failure

Area of Science:

• Transplant surgery
• Bariatric surgery
• Nephrology
• Hepatology

Background:

• Morbid obesity is a significant risk factor for complications and allograft failure in transplant recipients.
• Obesity negatively impacts transplant eligibility due to body mass index criteria.
• Existing data suggests bariatric surgery may be a viable option for pre-transplant weight management.

Purpose of the Study:

• To evaluate the safety and efficacy of bariatric surgery in patients with chronic kidney disease (CKD) and end-stage renal disease (ESRD).
• To assess the impact of bariatric surgery on transplant eligibility and postoperative immunosuppression.
• To review the role of bariatric surgery in patients with liver disease and portal hypertension.

Main Methods:

• Literature review of studies on bariatric surgery in pre- and post-transplant patients.
• Analysis of safety, efficacy, and complication rates associated with different bariatric procedures.
• Evaluation of impact on body mass index, kidney function, liver function, and immunosuppression.

Main Results:

• Bariatric surgery is safe and effective in CKD and ESRD patients, improving transplant eligibility without altering immunosuppressant needs.
• In liver disease patients, bariatric surgery is safe and effective, though portal hypertension remains a high-risk factor.
• Sleeve gastrectomy demonstrates low complication rates and significant weight loss, maintaining intestinal continuity.

Conclusions:

• Bariatric surgery can enhance transplant eligibility and outcomes for patients with morbid obesity and kidney or liver disease.
• Sleeve gastrectomy is a potentially valuable tool for pre- and post-transplant weight management due to its favorable safety and efficacy profile.
• Careful patient selection and consideration of comorbidities like portal hypertension are crucial for successful outcomes.
