Results
Global life satisfaction
 Satisfaction with Life Scale
(Diener, Emmons, Larsen, &
Griffin, 1985)
 Scores range from 5 (low
satisfaction) to 35 (high
satisfaction)
Groups did not differ significantly on:
 Time since most recent surgery
(7.6±1.7 yrs)
 Preoperative BMI at time of most
recent surgery (50.8±8.8 kg/m2)
 Current age (55.8±9.7 yrs)
 % Female (80.4)
Overall surgery satisfaction
 Assessed using a single 0-10
point Likert-type item
Groups differed significantly or trended
toward differing significantly on:

Discussion
Among RYGB bariatric surgery candidates,
previous history of bariatric surgery
appears to predict poorer weight loss and
satisfaction with surgery. The conclusion
regarding poorer weight loss is supported
by the findings that the groups in the
present study did not significantly differ
on key variables linked to postsurgical
weight loss, including age, time since
most recent surgery, and preoperative
BMI at time of most recent surgery.
Although those who received revisional
surgery to RYGB demonstrated outcomes
less favorable than primary patients, they
did nonetheless achieve significant
benefit and were relatively satisfied
overall. Results support the importance
of optimizing outcomes after primary
bariatric surgery and providing realistic
expectations about revision surgery
outcomes to
revisional
surgery
candidates.

Long-term outcome questionnaires were
collected from St. Vincent Bariatric Center
of Excellence bariatic surgery patients. All
patients received his/her most recent
bariatric surgery at St. Vincent Carmel’s
Bariatric Center of Excellence.

Overall Satisfaction with Surgery
A subset of bariatric surgery patients
undergo one or more revision surgeries for
inadequate
weight
loss
and/or
complications. Despite this, there are few
direct comparisons of weight loss and
psychological
functioning
outcomes
between primary bariatric surgery and
revision bariatric surgery patients. This
information may be useful in providing
revision bariatric candidates with more
accurate expectations for surgical
outcomes.

Revision Group
The present study defined presurgical
weight as the weight at the time of
revision surgery. Therefore, it is not clear
how weight loss outcomes between these
two groups would have compared had
presurgical weight been defined as weight
at time of first surgery. Future research
should address this question, as it may be
relevant to both primary and revisional
bariatric surgery candidates.
