Abstract
Background
Sleeve gastrectomy (SG) is one of the most commonly undertaken bariatric procedures.
Weight regain after bariatric surgery, when significant, may be associated with recurrence
of diabetes and deterioration in quality of life. Furthermore, it may be more common
after SG than bypass procedures. Yet the understanding of the significance of weight
regain is hampered by poor reporting and no consensus statements or guidelines.
Objectives
To illustrate how the lack of a standard definition significantly alters reported
SG outcomes and to contribute to the discussion of how weight regain should be defined.
Setting
Counties Manukau Health, a public teaching hospital that performs over 150 bariatric
procedures per year.
Methods
A retrospective cohort of SG patients followed up at 5 years was used to illustrate
how the presence of multiple definitions in the literature significantly affects outcome
reporting for weight regain. Post hoc analyses were used to explore the relationship
between weight change and clinical outcomes.
Results
Applying 6 definitions of weight regain to a retrospective cohort of SG patients resulted
in 6 different rates ranging from 9%–91%. Post hoc analyses revealed significant associations
between weight change and the Bariatric Analysis Reporting Outcome System (BAROS)
score as well as patient opinion.
Conclusion
The nonuniform reporting of weight regain appears to significantly affect SG outcome
reporting. Development of consensus statements and guidelines would ameliorate this
problem. Ideally, research groups with access to large robust databases would aid
in the development of any proposed weight regain definitions. In the interim, bariatric
literature would benefit by all published series clearly reporting how weight regain
is defined in the study population.
