Revisional bariatric surgery in a transplant patient.

Introduction: A BMI of over 35-45kg/m2 is deemed the upper limit for considering a patient for a renal transplant. Voluntary weight loss attempts are a major concern for patients while on hemodialysis, however, bariatric surgeries have opened up a new door to notable weight loss results, even demonstrating significant improvements of patients' diabetic profile and hypertension.

Case Report: Case of a 52-year-old male with a BMI of 42 in end-stage renal disease, that needed a kidney transplant but was ineligible to be placed on the waiting list due to his weight. A laparoscopic sleeve gastrectomy (LSG) was performed to aid with his weight loss. He also showed major improvements in his hypertension and diabetes profiles. The patient started gaining weight as well as showing deterioration in his diabetic control. He underwent the renal transplant 1.5 years post LSG, after which he showed improvements in his blood results, diabetic and hypertensive control. However, his weight began to increase again, for which he underwent gastric bypass. Since then, the patients' glucose, BUN and creatinine have normalized and his weight continued to drop, reaching a BMI of 31.83kg/m2 2 years post bypass.

Conclusion: Bariatric surgery is a safe and effective procedure to assist renal transplant patients in losing weight. In addition, it has proven to be effective in the management of the co-morbidities that are associated with renal failure. Our study was also able to prove that converting form an SG to a bypass in a transplant patient is a safe and feasible option.
