Abstract
Background
Among organ transplant recipients, a common side effect of immunosuppressive therapy
is the development of obesity, which affects a third of the patients within 3 years
after transplantation. Bariatric surgery represents a possible surgical option for
weight loss among posttransplant patients.
Objectives
The aim of this study was to examine percent excess weight loss (%EWL), and percent
weight loss (%WL) and perioperative and postoperative complications in posttransplant
obese patients after sleeve gastrectomy (SG) compared with nontransplant patients.
We hypothesize that transplant patients who undergo SG will not significantly differ
in their perioperative or postoperative complications or in their %EWL and %WL compared
with nontransplant patients who undergo SG. The second aim was to evaluate the impact
of SG on graft function and immunosuppressive therapy in transplant patients.
Setting
University hospital.
Methods
Among 500 consecutive patients who underwent SG from January 2008 to June 2014, 10
patients were organ transplant recipients. The following variables were compared between
groups: patient demographic characteristics and co-morbidities, type of transplant
surgery, date of transplant surgery, pretransplant body mass index (BMI), date of
bariatric surgery, prebariatric surgery BMI, operative time, length of hospitalization,
postoperative complications, and change in BMI, %EWL, and %WL. Data were also collected
on renal, liver, and pancreas graft function parameters and changes in immunosuppressive
medications.
Results
Six patients had a kidney transplant, 2 patients had a liver transplant, and 2 had
a pancreas transplant. No significant differences were observed in %EWL or %WL at
6 and 12 months follow-up between transplant and nontransplant patients. No transplant
patients were lost to follow-up at 6 and 12 months. Among nontransplant patients,
36.7% and 35.7% were lost to follow-up at 6 and 12 months, respectively. No postoperative
complications were registered in the transplant group. SG did not negatively affect
the graft function.
Conclusion
Initials results found that there were no significant differences in %EWL or %WL at
6 and 12 months follow-up between transplant and nontransplant patients. There were
also no perioperative and postoperative complications among transplant patients after
SG.
