Sleeve Gastrectomy After Liver Transplantation: Feasibility and Outcomes.

BACKGROUND

Knowledge regarding the feasibility and safety of sleeve gastrectomy (SG) in obese liver transplant recipients is scarce. We report our experience of sleeve gastrectomy following liver transplantation (LT).

METHODS

All patients who had undergone LT and subsequently underwent SG at our institution were retrospectively reviewed. Surgical outcomes, liver and kidney function tests, outcomes of obesity-related comorbidities, and excess weight loss were analyzed.

RESULTS

Between May 2008 and February 2015, six consecutive patients underwent SG after LT. Three procedures (50%) were performed totally by laparoscopy, and three by upfront laparotomy for concomitant incisional hernia complex repair. Within the first 30 days, one complication occurred: early gastric fistula that required multiple endoscopic procedures and re-intervention, followed by death 19 months after SG due to multi-organ failure. Another patient had one late complication: chronic infection on a parietal mesh successfully controlled by mesh removal. Excess weight loss averaged 76% at 2 years with a median BMI of 28 (21-39) kg/m. Median follow-up was 37.2 months (range 13-101 months). Median length of stay was 9 days (range: 6-81 days).

CONCLUSIONS

SG is technically feasible after LT and resulted in weight loss without adversely affecting graft function and immunosuppression. However, morbidity and mortality are high.
