ABSTRACT
Sweden (2). The procedure was an important part of the
Swedish Obese Subjects (SOS) study (3). However, prob-
lems including erosion, obstruction, inadequate weight
loss, and maladaptive eating behaviors precluded wide-
spread acceptance of the approach. In particular, with lack
of adjustability, the band was either too tight and the
patient had copious vomiting and maladaptive eating, or it
was too loose, resulting in disappointing weight loss.
Something better was needed.
