Abstract

Background

Obese individuals suffering from advanced chronic kidney disease (CKD) may be precluded from accessing kidney transplantation. Bariatric surgery is an effective treatment for obesity and related conditions but its use in those with severe CKD remains limited due to morbidity concerns. We aimed to evaluate the safety and efficacy of sleeve gastrectomy (SG) in patients with severe CKD as a bridging strategy towards kidney transplant candidacy.

Methods

This is a single-center retrospective study of a prospectively collected database of obese patients referred by the multi-organ transplant team for surgical weight loss, who underwent SG during 2013–2018. The primary outcome was 90-day major morbidity. Secondary outcomes included weight loss, and successful kidney transplantation. Descriptive statistics are expressed as count (percent) or median (interquartile range).

Results

32 patients met inclusion criteria. 18 (56%) were male with a median age and BMI of 51 (11) years and 42.3 (5.2) kg/m2, respectively. 29 (91%) patients were on dialysis for a median duration of 28 months before SG. Diabetes, hypertension, and dyslipidemia were present in 15 (47%), 25 (78%), and 21 (66%) patients, respectively. At 90 days after SG, there were no leaks, reoperations, or mortality. The median length of stay was 2 (1.3) days. At 1 year, change in BMI and percent excess weight loss (EWL) were −9.8 (3.7) kg/m2 and 56% (27), respectively. In the year after SG, 20 (63%) patients were listed for transplant. 14 (44%) underwent successful kidney transplantation. One patient died while waiting for transplant. At time of transplant, median change in BMI and EWL were −9.0 (5.5) kg/m2 and 59% (30), respectively. After transplant, no patient required dialysis at a median follow-up of 17 (32) months.

Conclusion

SG is safe and effective for weight loss and bridging to candidacy for kidney transplantation in patients with severe CKD. The acceptable safety and efficiency of SG in this high-risk population makes it an optimal choice as a bridging procedure.
